This paper aims to elucidate the important economic and political aspects of an extremely complex policy issue involving biological prospecting (bioprospecting) in Antarctica. In addressing this rapidly growing global industry, which searches for commercially valuable biological and genetic resources in a world of biological diversity, it becomes obvious that a critical interface exists between Antarctica and the intertwined bioprospecting policies brought forth during recent decades by two treaties, the Convention on Biological Diversity and the United Nations Convention on the Law of the Sea. The analytical framework of the paper builds upon the economic concept of public goods within a political framework of international treaties and law. The concept of a national public good, associated with the sovereignty of a state (nation) over its biological and genetic resources, is the basis of such policy under the Biological Diversity Treaty. In practice, this jurisdiction applies both to the land area of a state and to the exclusive economic zone of a coastal state. The Law of the Sea Treaty, on the other hand, provides both a national public good connotation to exclusive economic zones while creating a global public good connotation for deep seabed mineral resources, with a related potential application to bioprospecting in the deep seabed. While the Antarctic Treaty System possesses several institutions that could be adapted to a bioprospecting policy regime, no such regime has been established up to the present. The paper concludes with a consideration of the critical question: is bioprospecting in Antarctica a national or global public good? While logic would appear to lead one toward the ‘global’ answer, multinational economic and political realities in today's world suggest that either a national public good approach, or a largely unregulated open access approach, is more likely to prevail.

Abstract This paper explores economic aspects of a recent proposal to shift fisheries to a “Balanced Harvesting” (BH) strategy, as a means to achieve the goal, set by the Convention on Biological Diversity and related to the Ecosystem Approach to Fisheries, of “conservation of ecosystem structure and functioning” within fishery ecosystems. Studies indicate that a BH strategy—broadening the range of species and sizes caught in the aquatic ecosystem, and lowering exploitation rates for some conventionally targeted species—may provide improved ecological performance relative to conventional harvesting strategies. However, the potential economic implications have received little attention to date. This paper provides a preliminary economic assessment of BH, focusing on six main themes: (i) assessing benefits and costs, (ii) factors affecting the economics of BH, (iii) economic issues in implementing the ingredients of BH, (iv) effects of incremental and/or partial implementation of BH, (v) transition options within the harvesting sector of the fishery, and (vi) distributional impacts arising across fisheries, fleet sectors, and fishing gears, and between the present and the future.

Tropical rain forests are rich in plant and animal species. The sustainable extraction of non-timber forest products has been advocated as a strategy to best conserve this diversity. However, the development and implementation of such exploitation systems, which aim to reconcile conservation and economic development, are still hampered by the lack of information on the biological sustainability of these systems, the impact of these exploitation systems on the biological diversity and the insufficient knowledge of the role of forest products in the household economy of forest dependent people and hence their prospects for economic development. Whether the exploitation of non-timber forest products from tropical rain forests is sustainable or not is still open to question, but data presently available on the biological, social and economic aspects of these extraction systems point at an interesting question: does diversity come at a price? Namely, low density of conspecifics, and thus products, and hence low productivity for those involved in the collection of forest resources. The paper will further discuss whether domestication of forest species provides an alternative for some of these species. Species are part of a complex ecosystem and their functioning is partly depended on the presence of other species in the system. The attributes of the species which have to be taken into account in order to make domestication of forest species successful are considered. Finally, the paper returns to the question of how to reconcile conservation and use of tropical rain forests. It will present a case for domesticating the forest instead of the species or, in other words, changing the forest composition without changing its structure and functioning, and maintaining acceptable levels of biodiversity.

Abstract Development of ecological network of different taxonomic ranks is a weighty contribution to regional sustainable development. It proved to be among the most efficient ways to help preserve biological and landscape diversity. National eco-network in Ukraine is being formed alongside with European network. However, its development in this country is connected with certain problems existing on both national and local levels. Our analysis of national eco-network’s present-day state showed that Ukraine is rather successful in the concept’s realization. The network’s territory dynamically increases; legal and regulatory framework and methodical/applied approaches are being developed; and neighboring states are closely and intensely cooperated with in questions of formation of econetwork elements within boundary territories. However, the major goal - formation of eco-network as an integral system with its maximally possible continuity and inter-linkage of component elements - has not yet been achieved. The situation is explained by a number of problems occurring in juridical, economic and organizational spaces.

Both Southern Italy and Central China feature historic rural settlements characterized by underground constructions with residential and service functions. Many of these areas are currently tackling economic, social and environmental problems, resulting in unemployment, disengagement, depopulation, marginalization or loss of cultural and biological diversity. Both in Europe and in China, policies for rural development address three core areas of intervention: agricultural competitiveness, environmental protection and the promotion of rural amenities through strengthening and diversifying the economic base of rural communities. The challenge is to create innovative pathways for regeneration based on raising awareness to inspire local rural communities to develop alternative actions to reduce poverty while preserving the unique aspects of their local environment and culture. In this view, cultural heritage can be a catalyst for the sustainable growth of the rural community. Through a series of projects on a national and international scale, the authors have addressed some of these problems by exchanging best practices in conservation, sustainable use and the enhancement of the underground heritage.

The Bronze Age in Europe is characterized by major socio-economic changes, including certain aspects of animal husbandry. In the Alpine region archaeozoological data, though not very abundant, reveal that cattle were the most important domestic animals in this time period. They were probably used differently in the lowlands than at higher altitude, traction became more important and people increasingly exploited them for dairy products rather than for meat. Thus, a crucial question in this context is whether these major events are accompanied by changes in genetic diversity of cattle. Here we report partial mtDNA d-loop data (320 bp) obtained by PCR from 40 alpine cattle excavated at different sites in South Tyrol, Italy, and Grisons, Switzerland. Most cattle belong to the main European taurine T3 haplogroup, but a few members of T2 and Q haplogroups were identified. Moreover, genetic diversity measures and population genetic statistics indicate different cattle histories at different sites, including bottlenecks and potential admixture. However, Bronze Age Alpine cattle appear to be linked to modern rural cattle mainly from Italy.

Insects not only play a significant role in the ecological process of nature but since pre-historic times have also formed a part of the human diet. With a still growing population and skewed demographic structures across most societies of the world, their role as nutrient-rich food has been increasingly advocated by researchers and policymakers globally. In this study, we examine the edible insect diversity and entomophagy attitudes of ethnic people in Manas National Park, a UNESCO Natural World Heritage Site, located in Assam (India). The study involved a field investigation through which the pattern of entomophagy and the attitude towards insect-eating was studied. Following this, we examined the edible insect diversity and abundance at different sampling points. A total of 22 species of edible insects belonging to fifteen families and eight orders were recorded from different habitat types. Out of these 22 species, Orthopterans showed a maximum number of eight species followed by Hymenoptera (four), Hemiptera (three), Lepidoptera (two), Blattodea (two) and one species each from Coleoptera, Odonata, and Mantodea. Dominance, diversity, and equitability indices were computed along with the relative abundance of the insects concerning four habitat types. Aspects of the economic significance of entomophagy were also observed during the field investigation. To manage insects in the interest of food security, more attention should be given to sustainable collecting and rearing methods emphasizing their economic, nutritional, and ecological advantages.

ABSTRACTNew possibilities for economic development have been identified by the Greenland Home Rule Government in recent years. One of these is the potential for development of biotechnology based on Greenland's biodiversity. To ensure that Greenland shares in benefits derived from the exploitation of these resources the Home Rule Parliament recently enacted legislation on commercial and research-related use of biological resources that is premised on rights recognised by the 1992 Convention on Biological Diversity. This legislation represents the first law in an Arctic jurisdiction specifically to create a mechanism for access and benefit sharing in relation to Arctic genetic resources. The main area of research and commercial interest so far relates to potential developments in biotechnology from the microbial diversity of ikaite tufa columns located in the Ikka Fjord in southwest Greenland. The legislation seeks to provide a mechanism for regulating access to such biological resources and a means for Greenland to share in the potential benefits that may come from scientific research on them and subsequent commercialisation. Much research in Greenland now falls within the scope of this legislation. The purpose of this article is to explain the provisions of the legislation to the polar research community as well as to review its implications for research in the International Polar Year and later. The legislation imposes many new obligations on researchers in Greenland including obligations to obtain survey licences, obligations on reporting and the regulation of publication of scientific research. Commercially focussed research is also tightly regulated with a particular emphasis on patent rights. However, many aspects of the legislation are uncertain and it is unclear how much of the legislation will be implemented in practice.

Particular species of living organisms contribute to our natural environment in respective particular ways. Joined together, these species form biocenoses, able to run vital natural functions. Biogeocenoses that tightly link living and non-living organisms are the basis of ecosystems, our planet and human beings as biological species in particular, as later ones are fully dependent on the environmental condition. Determining the contributions of specific species and, subsequently, ecosystems is an essential aspect of human environmental policy. Determining the importance and value of biological diversity as well as understanding of its existence is a mandatory element of environmental policy of major industrial corporations and the basis of future economic decisions of all countries.

Diversity and habitat characteristics of macrozoobenthos in the mangrove forest of Lubuk Kertang Village, North Sumatra, Indonesia. Biodiversitas 19: 311-317. Mangrove plays an important role in coastal ecosystems including ecological, social, and economic aspects. This study aimed to determine the diversity of macrozoobenthos and water quality based on diversity index (H’), similarity Index (E), and dominance index (D) in the mangrove of Lubuk Kertang Village North Sumatra, Indonesia. The samples of macrozoobenthos (biological parameter) and water quality (physical and chemical parameters) were collected from fifteen plots in three different stations. Macrozoobenthos were collected in 1 m × 1 m transect in the mangrove forest. The biota was taken by using a shovel, inserted into a plastic bag, and identified. Results showed that eight species of macrozoobenthos were found and classified into three classes of Gastropod, Bivalvia, and Malacostraca. The highest diversity index (H′) of macrozoobenthos was found at Station II (2.39), the highest evenness index (E) was located at Station I (0.54), and the highest dominance index (D) was found at Station II (0.34). Principal component analysis (PCA) was used to determine the habitat characteristics of macrozoobenthos. PCA confirmed that station III was a habitat with suitable characteristics for the life of macrozoobenthos indicating the negative axis. The present study suggested four parameters namely salinity, clay temperature, and dissolved oxygen that should be preserved to support the survival of macrozoobenthos in the mangrove forests.

SummaryThe concept of risk requires preventative measures as well as measures of liability and redress in the case that damage is actually caused. The Cartagena Protocol on Biosecurity limits itself in Article 27 to the establishment of a mandate for the elaboration of norms and procedures in regard to liability and redress. The fulfillment of this mandate requires, first, a definition of the concept of damage to the conservation and sustainable use of biological diversity; second, a survey of the extent of damage to health; and, third, the consideration of socio-economic aspects. In this context, this article analyzes the concept of damage in the international instruments that deal with this material, taking into account levels of implantation. The article concludes by presenting a definition of damage for use in the context of the development of the content of Article 27, using an administrative focus in regard to the concept of damage for civil liability in domestic law.

Mycotoxins are ubiquitous and unavoidable harmful fungal products with the ability to cause disease in both animals and humans, and are found in almost all types of foods, with a greater prevalence in hot humid environments. These mycotoxins vary greatly in structure and biochemical effects; therefore, by better understanding the toxicological and pathological aspects of mycotoxins, we can be better equipped to fight the diseases, as well as the biological and economic devastations, they induce. Multiple studies point to the association between a recent increase in male infertility and the increased occurrence of these mycotoxins in the environment. Furthermore, understanding how mycotoxins may induce an accumulation of epimutations during parental lifetimes can shed light on their implications with respect to fertility and reproductive efficiency. By acknowledging the diversity of mycotoxin molecular function and mode of action, this review aims to address the current limited knowledge on the effects of these chemicals on spermatogenesis and the various endocrine and epigenetics patterns associated with their disruptions.

The rabbit (Oryctolagus cuniculus) is a unique multipurpose domestic species that has relevant economic impacts in several contexts. This review is focused on rabbit genetic resources that have been mainly bred for the fixation of differentiating features (e.g., exterior traits) that have been already genetically characterized. Several naturally occurring rabbit mutants could be useful as animal models for the investigation of the biological mechanisms determining their characterizing aspects, with translational potentials. A historical overview of the origin of the domesticated rabbit populations and of their genetic differentiation into many breeds is summarized. Then, a detailed analysis of the genetic features that characterize the different breeds is reported, starting from coat color and coat structure affecting genes (MC1R, ASIP, TYR, MLPH, TYRP1, KIT, LIPH, and FGF5), determining major loci described by classical genetic studies. Mutations in these genes have implications in pigmentation features, hair growth, and related defects. Other gene mutations affecting body size or shapes (HMGA2) and other physiological disfunctions (RORB and BCO2) are also described Additional studies are needed to complete the genetic characterization of some of these loci and to investigate the large genetic variability available in fancy breeds and commercial meat and fur lines.

As a signatory to Agenda 21, the Rio Declaration on Environment and Development, the 2030 Agenda for Sustainable Development (including the Sustainable Development Goals) and the Convention on Biological Diversity, Australia has an international obligation to ensure sustainable development. Biodiversity offsets are one tool used by Australian regulators to allow development to continue, whilst ensuring international obligations for sustainable development are met. In this study, legislation, policy and published guidelines for the Australian Commonwealth, states and territories were analysed to determine if the application of biodiversity offsets was consistent with the principles of sustainable development (environmentally, socially, economically) and if the allowance of biodiversity offsets in different jurisdictions created gaps in biodiversity and environmental protection across Australia. Regulation of biodiversity offsets was found to be inconsistent between the Commonwealth and the states and territories, with most jurisdictions having less than 50% similarity. This inconsistency in offset policy and legislation between jurisdictions could lead to loss of biodiversity. Additionally, jurisdictions did not adequately consider the social and economic aspects of sustainability in relation to biodiversity offsets, meaning that, through the allowance of biodiversity offsets, Australia may not be meeting their international obligations related to sustainable development. Further legislative development for biodiversity offsets is required in Australia to improve environmental protection and to adequately consider all aspects of sustainability. The Council of Australian Governments is a mechanism that could be used to ensure all jurisdictions consider the aspects of sustainability consistently in relation to biodiversity offsets.

Global climate change has the potential to substantially alter the production and community structure of marine fisheries and modify the ongoing impacts of fishing. Fish community composition is already changing in some tropical, temperate and polar ecosystems, where local combinations of warming trends and higher environmental variation anticipate the changes likely to occur more widely over coming decades. Using case studies from the Western Indian Ocean, the North Sea and the Bering Sea, we contextualize the direct and indirect effects of climate change on production and biodiversity and, in turn, on the social and economic aspects of marine fisheries. Climate warming is expected to lead to (i) yield and species losses in tropical reef fisheries, driven primarily by habitat loss; (ii) community turnover in temperate fisheries, owing to the arrival and increasing dominance of warm-water species as well as the reduced dominance and departure of cold-water species; and (iii) increased diversity and yield in Arctic fisheries, arising from invasions of southern species and increased primary production resulting from ice-free summer conditions. How societies deal with such changes will depend largely on their capacity to adapt—to plan and implement effective responses to change—a process heavily influenced by social, economic, political and cultural conditions.

Current awareness about the environmental impact of intensive agriculture, mainly pesticides and herbicides, has driven the research community and the government institutions to program and develop new eco-friendly agronomic practices for pest control. In this scenario, integrated pest management and integrated weed management (IWM) have become mandatory. Weeds are commonly recognized as the most important biotic factor affecting crop production, especially in organic farming and low-input agriculture. In herbaceous field crops, comprising a wide diversity of plant species playing a significant economic importance, a compendium of the specific IWM systems is missing, that, on the contrary, have been developed for single species. The main goal of this review is to fill such gap by discussing the general principles and basic aspects of IWM to develop the most appropriate strategy for herbaceous field crops. In particular, a 4-step approach is proposed: (i) prevention, based on the management of the soil seedbank and the improvement of the crop competitiveness against weeds, (ii) weed mapping, aiming at knowing the biological and ecological characteristics of weeds present in the field, (iii) the decision-making process on the basis of the critical period of weed control and weed thresholds and iv) direct control (mechanical, physical, biological and chemical). Moreover, the last paragraph discusses and suggests possible integrations of allelopathic mechanisms in IWM systems.

This study to examine legal aspect, why always happen and impact of forest fire in Indonesia. The conclusion are, even though there is a forestry law as regulated in Law No. 41/1999 on Forestry, as amended by Law Number 19/2004, forest fires have been repeated several large scale since the early 1980s until now. The case of Indonesia which was experiencing forest fires is a manifestation of unclear and poorly enforced policies, economic forces that push business to use fire to clear land, lack of technological alternatives, poor public participation and aggravated by climatic condition such as the extended drought. Although many policies have already been formulated and special management agencies have been established, policies implementation remain weak, coordination is poor and the current system is inefficient. Added to these factors, is the reality that government official’s business leader and general public lack a sense of urgency about the fires. Fires can impede national economic performance and increase poverty at the local level. It is mostly that disaster until now will repeat/recur unless definitive steps are taken to encourage short term and long term prevention strategies. Fires cause tremendous ecological impacts such as air quality, hydrological cycle, biological diversity, natural succession, disruption of the production and decomposition of organic materials, soil, disruption in the nutrient cycle, climate regulation and carbon sink; social impact such as food security, impact on health such as death, asthma, ARI, and impact on economic such as, agriculture, forestry, health, transmigration, transportation and tourism.

Sustainability in animal breeding can be understood as continuous availability of breeding animals and their germinal products for commercial production, that now and in the future, meet the requirements of a broad range of stakeholders: breeders, farmers, livestock keepers, producers, consumers and others, while respecting animal welfare and promoting more sustainable agriculture. Breeding goals are established to contribute to fulfilling various aspects of sustainability: quality, diversity, acceptability, environment and economics. Government policies and strategies have major impacts on animal breeding; they provide the basis for establishing the legal landscape for national priorities for livestock sector development and provide for institutional arrangements and control measures. Implementation of international agreements supports policy development for sustainability in animal breeding and production. The Global Plan of Action for Animal Genetic Resources was prepared to directly contribute to sustainable management of livestock calling for improved characterization, monitoring, breeding and conservation. The Convention on Biological Diversity calls for the conservation of genetic diversity, including agricultural genetic resources. Animal breeding and strategies for livestock development require long-term policy perspectives, as poor decisions can have lasting detrimental effects. This paper is intended to highlight the importance of policy development in efforts to achieve sustainability in the livestock sector.

In order to operationalise the concept of biodiversity for biological variety, it has been applied at three levels: ecosystems, species and genetic diversity. In most cases the debate has been reduced to the aspect of the variety of species, ignoring the fact that the interactions are considerably more complex. In order to do justice to our responsibility for diversity, further efforts are needed, which could be subsumed under the heading “sustainable development”. At the moment, however, our ecological footprint is clearly too big. A strong focus must therefore be placed on such ecosystem services as fertility of the soil, carbon sequestration, maintenance of the hydrological balance, etc. That ultimately leads to economic arguments, which in turn will have massive impacts on current land use policies. Climate change and the increasing cultivation of biofuels are creating new effects, whose impacts on biodiversity were until recently unforeseeable. The underlying message must accordingly be that in the biodiversity debate we must focus on the landscape as such and an appropriate land use policy.

The Red Sea is one of the key areas of biodiversity in the world. It is a hotspot for speciation and biological invasions. In the current work, a pilot, random sampling trial was carried out to characterize some species in the landings reaching the fish market in Suez city, which is one of the largest fish markets in the Northern Red Sea. Samples of different fish species were subjected to the standard procedures of DNA barcoding, applying the sequencing of the cytochrome oxidase subunit 1 mitochondrial gene (COI). DNA barcoding could successfully identify all the targeted fishes to the species-level (>98%). The results exhibited a taxonomically-versatile commercial trends in this market, being the collected species belonging to 7 different fish families and 3 orders. These species were Coris aygula, Papilloculiceps longiceps, Priacanthus sagittarious, Gerres longirostris, Alepes djedaba, Psettodes erumei Cheilinus trilobatus, Calotomus viridescens, and Pardachirus marmoratus. Haplotype diversities in the first six species were moderate. However, their nucleotide diversities were low. This may have resulted from fishing from bottlenecked populations, or from areas that do not hinder the genetic flow. Also, possible cryptic speciation could be detected in P. sagittarius, P. erumei and G. longirostris. Applying the DNA barcoding for species identification in Suez city fish market could then detect various aspects of fish species diversity. More works using the applied analyses can be strongly recommended to aid proper conservation and management of economic fisheries in the Red Sea.

The article deals with the features of the current state and development of the Caspian geopolitical space, which is known as "Greater Caspian Region". The uniqueness of the natural complex is distinguished by the unity of the Caspian ecosystem, biological diversity, and inexhaustible recreational opportunities. The natural resource and capacities in transportation and communication links of the region represent the Great Caspian Sea as one of "the world's largest oil and gas hydrocarbon deposits" (Hoagland, 2019, p. 10-11). As a special geopolitical and economic space, the Caspian Sea is also united by a long shared history, culture and identity of the peoples who lived within the territory. (Romanova, 2012). "Greater Caspian Region" or "the Central Region of Eurasia", through which new models of international relations is constructed between the world leaders in this area, takes a new look at the Eurasian space and allows to describe the region through modern science paradigm considering the latest geopolitical developments and interdisciplinary research. Under the emergence of new world economic order, the Caspian Sea can be represented as an "island of interfacing worlds" - "East and West", as a geopolitical space that attracts the world's leading players and where a new multipolar world order that is based on the "rift" of the technological and world economic structures develops (Markelov, Golovina, 2020, p.16). This paper studies a set of basic aspects of a new approach to assessing the Caspian region, establishing its current geopolitical and geo-economic positions, as well as promising areas for strategic research and development. The object of this study is the geopolitical concept of the " Greater Caspian Region", the subject is the problems of: The Greater Caspian Sea; Eurasia; space; security; development strategy; geopolitics; the new world economic order. The objective of this research is to create an integrated analytical security system in the Caspian region that takes into account political and geographical factors, in their relation to economy, environment and information flows.

Microorganisms area treasure in terms of theproduction of various bioactive compounds which are being explored in different arenas of applied sciences. In agriculture, microbes and their bioactive compounds are being utilized in growth promotion and health promotion withnutrient fortification and its acquisition. Exhaustive explorations are unraveling the vast diversity of microbialcompounds with their potential usage in solving multiferous problems incrop production. Lipopeptides are one of such microbial compounds which havestrong antimicrobial properties against different plant pathogens. These compounds are reported to be produced by bacteria, cyanobacteria, fungi, and few other microorganisms; however, genus Bacillus alone produces a majority of diverse lipopeptides. Lipopeptides are low molecular weight compounds which havemultiple industrial roles apart from being usedas biosurfactants and antimicrobials. In plant protection, lipopeptides have wide prospects owing totheirpore-forming ability in pathogens, siderophore activity, biofilm inhibition, and dislodging activity, preventing colonization bypathogens, antiviral activity, etc. Microbes with lipopeptides that haveall these actions are good biocontrol agents. Exploring these antimicrobial compounds could widen the vistasof biological pest control for existing and emerging plant pathogens. The broader diversity and strong antimicrobial behavior of lipopeptides could be a boon for dealing withcomplex pathosystems and controlling diseases of greater economic importance. Understanding which and how these compounds modulate the synthesis and production of defense-related biomolecules in the plants is a key question—the answer of whichneeds in-depth investigation. The present reviewprovides a comprehensive picture of important lipopeptides produced by plant microbiome, their isolation, characterization, mechanisms of disease control, behavior against phytopathogens to understand different aspects of antagonism, and potential prospects for future explorations as antimicrobial agents. Understanding and exploring the antimicrobial lipopeptides from bacteria and fungi could also open upan entire new arena of biopesticides for effective control of devastating plant diseases.

Purpose. To determine the key principles of environmental security of aquatic ecosystems in the context of sustainable use of natural resources and socio-economic development. Methodology. Comparative analysis and systematic approach. Findings. Principal aspects of water resources management in the states of the world are analyzed in the context of the provisions of the sustainable development concept. Comparison of countries with different levels of development has allowed identifying key methodological provisions that are implemented in the environmental policy ofwater. An approach to determination of the limiting indices of the impact on the environment is proposed. It was revealed that most post-Soviet countries do not use the concept of ecological system and ecosystem services in their legislative framework, which today are an integral part of the environmental policy and legislation of developed countries. The basic principles of the ecological safety of aquatic ecosystems are as follows: a water body (surface or underground ones) is a complex, functionally integrated and self-regulating ecological system. It cannot be considered as a volume with a resource for biological and amenity needs; priority in the water use should be given to the living components that exist in it and ensure its functional integrity. Any aquatic ecosystem should be economically assessed not only in terms of available water resources, but also considering other ecosystem services, particularly, the diversity of its biotic components. All these principles and the approach presented, if introduced into domestic legislation, will allow achieving progress in the field of ecological safety of aquatic ecosystems and sustainable social economic development. Originality. An approach has been improved which determines the efficiency of environmental policy in the field of water resources safety through a correlation analysis of water consumption and population size. Practical value. The research results allow for quantitative assessment of water resource management. The results of the study on the influence of the factor of freshwater resources on the socio-economic development of countries and regions of the world suggest that there is a strong statistically significant correlation in this system of connections.

The Lepidoptera is one of the most widespread and recognisable insect orders. Due to their remarkable diversity, economic and ecological importance, moths and butterflies have been studied extensively over the last 200 years. More recently, the relationship between Lepidoptera and their heritable microbial endosymbionts has received increasing attention. Heritable endosymbionts reside within the host’s body and are often, but not exclusively, inherited through the female line. Advancements in molecular genetics have revealed that host-associated microbes are both extremely prevalent among arthropods and highly diverse. Furthermore, heritable endosymbionts have been repeatedly demonstrated to play an integral role in many aspects of host biology, particularly host reproduction. Here, we review the major findings of research of heritable microbial endosymbionts of butterflies and moths. We promote the Lepidoptera as important models in the study of reproductive manipulations employed by heritable endosymbionts, with the mechanisms underlying male-killing and feminisation currently being elucidated in moths and butterflies. We also reveal that the vast majority of research undertaken of Lepidopteran endosymbionts concernsWolbachia. While this highly prevalent bacterium is undoubtedly important, studies should move towards investigating the presence of other, and interacting endosymbionts, and we discuss the merits of examining the microbiome of Lepidoptera to this end. We finally consider the importance of understanding the influence of endosymbionts under global environmental change and when planning conservation management of endangered Lepidoptera species.

The tropical western South Atlantic, which includes a substantial portion of the Brazilian Exclusive Economic Zone, is a region of endemism broadly recognized as being of prime importance for the conservation of the marine biodiversity. The north coast of Brazil, which comprises the states of Amapá, Pará and Maranhão from the mouth of the rio Oiapoque to the mouth of the rio Parnaíba, harbors the largest continuous mangrove in the world, with approximately 8,900 km2. The high discharge of freshwater and continental sediments in the delta of the Amazonas affects the regime of tides, ocean currents, and several oceanographic processes of the north coast, with direct impact on the composition of the biota found in the region. Despite its economic value and intrinsic biological relevance, several aspects of the diversity of the marine and estuarine fishes of the region are poorly known. This situation results mainly from a historical imbalance in terms of the number of studies devoted to increasing the knowledge of the marine biota along the Brazilian coast, such as those dealing with species inventory and taxonomic revisions, which are typically concentrated in the south and southwestern portions of the country. The scientific production focused on marine organisms of the north coast is also imbalanced, and reflects the relatively small number of taxonomists and research groups working on that subject. The insufficient knowledge of the biodiversity of the marine and estuarine fishes of the north coast is an impediment to the implementation of adequate public policies aimed at the management of natural resources in the region. In the long term, that situation is potentially harmful in terms of conservation of a still poorly known biota. A better understanding of the marine fish fauna of the north coast of Brazil will be achieved only through the investment in scientific research and personnel training in systematics and biogeography, coupled with the modernization of the current infrastructure and expansion of scientific collections of the region.

The National Biodiversity Strategy and Action Plan (NBSAP), formulated from 2000 to 2003, was envisaged as a comprehensive action plan for conserving biodiversity in India, that would adequately reflect the aspirations of the hitherto marginalised peoples who have a direct stake in biodiversity conservation. For the first time, a truly participatory approach was adopted for environmental conservation and planning in India. For a country of India's size, biological and cultural diversity and immense social and economic divides, this has been no easy task for Kalpavriksh Environmental Action Group, the NGO with whom the Government of India is collaborating to formulate the NBSAP. In this article, the process and products of the NBSAP are reviewed, outlining its aims, the extent to which these have been met and the limitations in the process of its formulation. Through 33 state-level, 18 local-level and 10 inter-state level plans, the draft National Biodiversity Strategy and Action Plan (NBSAP) recommends a series of bold measures to ensure that the country's ecological security is ensured. These measures call for a major reorientation of the process of economic development and of governance of natural resources, such that the health of the environment, and the livelihoods of biomass-dependent communities become central to all planning. The NBSAP process has been highly successful with respect to degree of involvement of local communities, development of linkages with ongoing conservation action, integration of cross-cutting issues such as globalisation and livelihood into conservation planning, and comprehensive assessment of various aspects of biodiversity. Implementation of the NBSAP has already begun in parts of nine states without external support, showing the high level of impact it has had on active citizens’ groups and governmental bodies. However, the planning process suffered from a number of inadequacies such as ineffective networking with some critical sections of the public such as religious leaders and corporate houses and unsatisfactory degree of involvement of women.

Lindera glauca (Lauraceae) is a tree of economic and ecological significance that reproduces sexually and asexually via apomictic seeds. It is widely distributed in the low-altitude montane forests of East Asia. Despite the potential implications of a mixed reproductive system in terms of genetic diversity, few studies have focused on this aspect. In this study, the genetic structure of wild populations of L. glauca was investigated via genetic analyses. Overall, 13 nuclear microsatellites (nSSRs) and five chloroplast microsatellites (cpSSRs) were used to genotype 300 individual plants, taken from 20 wild populations (a small sample size in some wild populations is due to the limitation of its specific reproduction, leading to certain limitations in the results of this study) and two cultivated populations ranging across nearly the entire natural distribution of mainland China. The populations exhibited low levels of genetic diversity (nSSR: AR = 1.75, Ho = 0.32, He = 0.36; cpSSR: Nb = 2.01, Hrs = 0.40), and no significant effect of isolation by distance between populations existed, regardless of marker type (nSSR: R2 = 0.0401, P = 0.068; cpSSR: R2 = 0.033, P = 0.091). Haplotype networks showed complex relationships among populations, and the H12 haplotype was predominant in most populations. Analyses of molecular variance obtained with nuclear markers (Fsc = 0.293, FST = 0.362) and chloroplast markers (Fsc = 0.299, FST = 0.312) were similar. The migration ratio of pollen flow versus seed flow in this study was negative (r = −1.149). Results suggest that weak barriers of dispersal between populations and/or the similarity of founders shared between neighbors and distant populations are indicative of the gene flow between populations more likely involving seeds. Wild L. glauca in mainland China was inferred to have highly skewed sex ratios with predominant females. In addition, some populations experienced a recent bottleneck effect, especially in Gujianshan, Chongqing, and southwest China (population GJS). It is suggested that few wild male individuals should be conserved in order to maintain overall genetic diversity in the wild populations of this species. These findings provide important information for the sustainable utilization and preservation of the overall genetic diversity of L. glauca.

Shade tolerance (the capacity to survive and grow over long periods under shade) is a key component of plant fitness and the foundation of current theories of forest succession in tropical rain forests. It serves as a paradigm to understand the optimal allocation of limited resources under dynamic light regimes. I analyze how tropical rain forest succession influences the expression of ecophysiological mechanisms leading to shade tolerance, and identify future areas that will increase our understanding of the ecological and evolutionary consequences of this phenomenon. Shade tolerance is a multivariate, continuous functional trait reflecting the growth-mortality trade-off of investing resources under limited light vs. exploiting high light conditions. I propose the life cycle successional trajectory model of Gómez-Pompa & Vázquez-Yanes as an integrative tool to understand tropical rain forest succession. This model shows how species distribute along the successional environmental gradient based on their degree of shade tolerance and represents a more integrative paradigm to understand the interface between different aspects of species diversity (ontogenetic variation and functional diversity) throughout succession. It proposes that different trait combinations determining shade tolerance are expressed at different stages of the life cycle, which affects how and when plants enter the successional trajectory. Models explaining the expression of shade tolerance (resource availability, carbon gain, CSR, resource competition) are based on whole-plant economics and are not mutually exclusive. The analysis of shade tolerance is biased towards tree seedlings in the understory of mature forests. Other life stages (juvenile and adult trees), life forms, and microhabitats throughout the forest profile are almost always excluded from these analyses. More integrative explanations based on the distribution of functional traits among species, ontogenetic stages, and the nature of the environmental gradient are being developed based on long-term data and chronosequence comparisons. In summary, shade-tolerance is a complex phenomenon, is determined by multiple characters that change ontogenetically over space and time and entails considerable plasticity. Current methods do not account for this plasticity. Understanding the nature of shade tolerance and its functional basis is critical to comprehending plant performance and improving the management, restoration and conservation of tropical rain forests given the combined threats of global warming and habitat loss

SummaryBrazil’s rich biological and cultural diversity makes it an exceptional location for examining the commerce in live wild birds and its implications for conservation. This paper catalogues the live bird species being traded in Brazil, characterises the trade in these animals, and discusses the implications for avian conservation. In spite of being illegal, capturing and selling birds is still a very common practice in Brazil and involves many actors who make up part of a large commercial network that distributes wild animals to every corner of the country. Our survey revealed that at least 295 bird species are illegally sold as pets in Brazil, with estimates derived from this data pointing to a total of more than 400 species - about 23% of the number of extant bird species in the country. Of the bird species recorded, two were classified as “Critically Endangered”, nine as “Endangered”, six as “Vulnerable”, and 19 as “Near Threatened” according to the most recent IUCN Red List. Most of the species recorded in this study as being widely bought and sold (including on the international market) are not listed by CITES even though many of them are in fact threatened. In light of the widespread illegal trade in wild birds in Brazil and the conservation implications for the species involved, there is an urgent need for actions that can control these activities. Steps should be taken to address the illegal traffic directly and these must include monitoring, law enforcement, effective sentencing (including deterrent sentences), targeting end-users, captive breeding, and education at all levels, taking into account the cultural, economic, social, and ecological aspects of the human populations involved.

The ecological model theory highlights that human development (or a given behavior) is the result of the interaction of variables derived from different levels, comprising those directly related to the subjects and those related to the environment. Given that, the purpose of this study is to establish whether runners’ performance may vary among different Brazilian states, as the factors associated with this difference. The sample comprised 1151 Brazilian runners (61.8% men) that completed an online questionnaire, providing information about biological (sex, age, height, and weight), training (running pace, frequency and volume/week, and motivation), sociodemographic (place of residence and wage) aspects, and perceptions about the environmental influences on the practice. Information about state variables was obtained from official institutes, and comprised the human development index (HDI), athletics events, and violence index. Multilevel analysis was conducted in HLM software. State-level characteristics explained ≈3% of the total variance in running performance. Of the total variance explained for the individual level, 56.4% was associated with male sex (β = −54.98; p < 0.001), age (β = 1.09; p < 0.001), body mass index (β = 6.86; p < 0.001), economic status (β = 6.23; p = 0.003), the perception of the natural environment (β = 7.58; p = 0.02), training frequency (β = −16.64; p < 0.001), and weekly volume (β = −0.30; p < 0.001). At the state level, only athletics events presented a positive and significant influence on performance. There is a significant role of the environment on the explanation of running performance variability, and given the diversity across states, environmental variables should not be neglected, as they are relevant to the exploration of other variables possibly related to running performance.

Proceedings of the International conference (ИнтерКарто. ИнтерГИС, Russia) devoted to geographical information systems for sustainable development of territories have been published annually since 1994. The articles discuss theoretical and methodological aspects of geoinformation support for environmental, economic and social aspects of sustainable development, issues of geoinformatics, cartography, remote sensing of the Earth, problems of environmental sustainability and environmental impact assessment. Over a quarter of a century, the conference proceedings got more than 125 articles related to the use of geoinformation technologies to the study and mapping of vegetation. The review of proceedings gives the concrete examples how to solve problems of vegetation mapping using GIS, it is focused on publications providing some examples of GIS application to the vegetation studies. The review is organized into thematic sections according the field of application of Geoinformatics: 1.Vegetation, 2. Dynamics, state and ecological functions of vegetation, 3. Biodiversity and its assessment, 4. Plant resources, 5. Monitoring of vegetation. The Vegetation section contains publications on vegetation studies and mapping performed for some regions of Russia — the North of the Far East, the Republic of Sakha (Yakutia), the Tyva Republic, Central Siberia, and others. More than half of the articles are devoted to vegetation dynamics, state and ecological functions of vegetation at different hierarchical levels. Some papers present the results of the studies based on new types of information sources (photographs) and visualization methods (animation). The use of geoinformation technologies to study biological diversity was included in the agenda of five conference sessions and later reflected in more than ten publications. They cover the development and creation of GIS, the use of geoinformation technologies for the analysis, assessment and mapping of biodiversity, for its monitoring and conservation. Quite a large number of articles are devoted to the study of forest resources. GIS technologies were used to solve problems of forest management, cartometric analysis of forested areas, determination of taxation indicators, systematization of forest conditions, etc. Examples of geoinformation versatile research for medicinal plant resources are given to assess their quality, resources and productivity in the region, to identify growing areas, including ones to be protected. Most of the published materials concerning to vegetation monitoring mainly relate to forests and forest management.

Biobanks, which contain human biological samples and/or data, provide a crucial contribution to the progress of biomedical research. However, the effective and efficient use of biobank resources depends on their accessibility. In fact, making bio-resources promptly accessible to everybody may increase the benefits for society. Furthermore, optimizing their use and ensuring their quality will promote scientific creativity and, in general, contribute to the progress of bio-medical research. Although this has become a rather common belief, several laboratories are still secretive and continue to withhold samples and data. In this study, we conducted a questionnaire-based survey in order to investigate sample and data accessibility in research biobanks operating all over the world. The survey involved a total of 46 biobanks. Most of them gave permission to access their samples (95.7%) and data (85.4%), but free and unconditioned accessibility seemed not to be common practice. The analysis of the guidelines regarding the accessibility to resources of the biobanks that responded to the survey highlights three issues: (i) the request for applicants to explain what they would like to do with the resources requested; (ii) the role of funding, public or private, in the establishment of fruitful collaborations between biobanks and research labs; (iii) the request of co-authorship in order to give access to their data. These results suggest that economic and academic aspects are involved in determining the extent of sample and data sharing stored in biobanks. As a second step of this study, we investigated the reasons behind the high diversity of requirements to access biobank resources. The analysis of informative answers suggested that the different modalities of resource accessibility seem to be largely influenced by both social context and legislation of the countries where the biobanks operate.

Purpose – The purpose of writing this paper is to present a comparative but critical assessment of the applicability of the precautionary principle (PP) under the SPS Agreement, which is a part of the WTO regime by implication, and under the Cartagena Protocol, which has been made under the Convention on Biological Diversity. Design/methodology/approach – The paper presents an analytical exposition of both the sets of laws, trade law and environmental law. The methodology adopted is library based. The approach is to bring about an amicable co-existence of both the laws so that they could serve the dual purpose, i.e. promotion of trade and protection of “human, animal and plant life and health” and conservation of the environment. Findings – The DSB of the WTO should give due importance to the PP and should apply it liberally, keeping also in view the environmental aspects, so that along with free trade human, animal and plant health and life, and conservation of the environment are also protected. Practical implications – It will change the present paradigm and will bring both the sets of laws together. Originality/value – It focuses on the life and heath of poor people around the world.

Abstract In Brazil, given its privileged hydrology, the unexplored economic use of water resources has many dimensions, such as hydroelectric power. This energy will face increasingly rigorous social and environmental impact assessments (40% of potential is located in the Amazon region). Hydropower inventory studies conducted over decades, with solutions such as ecological river flows, that flood smaller areas and reduce natural river flows modifications, are being reviewed. The river extension from dam to the point where the waters are returned after the powerhouse is known as the Reduced Flow Stretch (RFS). Even mega-projects, such as the 11.3 GW Belo Monte dam, are designed with deviating flows reaching an astounding 13,000 m 3/s (excavated material higher than Panama Canal). RFS requires to be carefully studied to achieve appropriate ecological flows, since RFS flows increased reduces the plant's electricity production to the same installed capacity. Balancing RFS requirements and hydroelectric power remains a challenge and, clearly, there is no consensus. Here, we performed an analysis of the main environmental impacts caused by RFS requirements, considering the multiple water use specific for each dam site. The natural variability of river flows provides diversity of habitats and maintains the richness and complexity of biological communities. Therefore, the present study has great ecological, social and economic relevance, since proper evaluation of the RFS requirements avoids potential destabilization of biological communities and even loss of biodiversity. This type of arrangement was more common in dams located in headwaters of rivers, as in the slopes of the Andes mountain range, and in regions like the Alps. There are many hydroelectric plants in South America and Europe that have this type of arrangement of engineering works. But the times are different and the environmental impacts have to be better evaluated. A final aspect also involves the maintenance of ecological flows downstream of dams. Regularization reservoirs need to keep downstream, even if they do not have a TVR, adequate flows that represent minimally the seasonality of the river, with floods and droughts, that propitiate the maintenance of the ecosystems downstream. There are cases such as the Sobradinho Plant in the São Francisco River that has been much questioned in this regard, especially when the climate is changing in the basin, with long periods of drought, and with increasing water use. So this is a very important and increasingly current issue.

Much of the current innovation in advanced materials is occurring at the nanoscale, specifically in manufactured nanomaterials (MNs). MNs display unique attributes and behaviors, and may be biologically and physically unique, making them valuable across a wide range of applications. However, as the number, diversity and complexity of MNs coming to market continue to grow, assessing their health and environmental risks with traditional animal testing approaches is too time- and cost-intensive to be practical, and is undesirable for ethical reasons. New approaches are needed that meet current requirements for regulatory risk assessment while reducing reliance on animal testing and enabling safer-by-design product development strategies to be implemented. The adverse outcome pathway (AOP) framework presents a sound model for the advancement of MN decision making. Yet, there are currently gaps in technical and policy aspects of AOPs that hinder the adoption and use for MN risk assessment and regulatory decision making. This review outlines the current status and next steps for the development and use of the AOP framework in decision making regarding the safety of MNs. Opportunities and challenges are identified concerning the advancement and adoption of AOPs as part of an integrated approach to testing and assessing (IATA) MNs, as are specific actions proposed to advance the development, use and acceptance of the AOP framework and associated testing strategies for MN risk assessment and decision making. The intention of this review is to reflect the views of a diversity of stakeholders including experts, researchers, policymakers, regulators, risk assessors and industry representatives on the current status, needs and requirements to facilitate the future use of AOPs in MN risk assessment. It incorporates the views and feedback of experts that participated in two workshops hosted as part of an Organization for Economic Cooperation and Development (OECD) Working Party on Manufactured Nanomaterials (WPMN) project titled, “Advancing AOP Development for Nanomaterial Risk Assessment and Categorization”, as well as input from several EU-funded nanosafety research consortia.

Ecological and socioeconomic aspects of subterranean hydrosystems have changed during the past 40–50 years. The major environmental pressures (mainly anthropogenic ones) impact the quantity and quality of groundwater resources and the state of subsurface ecosystems, and it is expected that the environmental pressures on groundwater will continue, at least until 2025, unless new environmental policies change this state of affairs. The world demographic increase and the general rise of water demand constitute one of the major environmental pressures on groundwater ecosystems especially in less developed countries in Africa, Asia and South America. Specific human activities leading to the depletion of groundwater reserves include agricultural practices, landscape alteration, urbanization demand for domestic and public drinking water, various industrial activities such as thermoelectric production and mining, and the rise of tourism in coastal areas. Climate change is contributing to the water crisis too, especially in areas with arid climate and/or in some humid monsoonal countries. The overload of aquifers with pollutants derived from agriculture (fertilizers and pesticides), from industry (release of hydrocarbon chemicals, especially spills), from waste and industrial waters, from domestic and industrial landfills, from the infiltration of pollutants from surface and from the intrusion of saline water affect groundwater quality. The dangerous increase in contaminated subsurface sites with chemicals and microbial pathogens brings with it health risks to humans. Changes of redox condition in groundwater zones, changes of biological diversity, vegetation changes with modification of agriculture practices and impacts at the biosphere scale, such as the increase in the concentration of nitrous oxides in the atmosphere, all impact groundwater ecosystems. Groundwater ecosystems must be better investigated and understood. Economic, social and ecological lines of thinking have to be combined in order to achieve meaningful policies for the sustainable development of groundwater reserves and for the protection of subsurface ecosystems. Practical measures and ideas for the development of policies up to the 2025 time-horizon should improve the sustainable usage of the world's groundwater resources.

One of the main reasons for the priority of science education is the change of priorities in relation to person with his environment, the transition from anthropocentric to ecocentric environmental consciousness. Construction of the content of ecological education, formation of ecological culture is determined on the basis of a set of principles: philosophical and methodological, methodical and didactic and organizational and pedagogical. The new paradigm of higher education is organizationally embodied in multilevel and diversification. The semantic and technological components of the restoration of education have not yet been fully worked out, and therefore require in-depth study and psychological and pedagogical justification, without which new initiatives risk remaining more or less successful empirical inclusions in the traditional education system. The basic principles of innovative education can and should be the basis for the analysis of new functions and new content of science education. Within the new paradigm, science education can and should become a socially and personally significant factor, thanks to the huge content, cognitive, ideological and methodological potential of its foundations. The new paradigm of science education, based on its conceptually new principles, should, at the same time, contributes to reaching a qualitatively new level of the most important characteristic of modern education – its integrity. Preservation of the integrity and diversity of natural ecosystems is a condition for maintaining the spiritual and physical health of man, its biological existence. Therefore, there is a need to create a stable balance between human economic interests, on the one hand, and the preservation of its environment – on the other. A person must change himself to eliminate the existing priorities of the economy over the environment. To do this, it is necessary to fill the education system with new content, to form a knowledge base through which the individual and society as a whole could come to balance. The supra-subject and integrative nature of ecology and economy in many aspects determines their system-forming role in the educational process.

<p class="Corpoica">Múltiples estudios han mostrado los beneficios ambientales, económicos y productivos que se pueden generar al incluir vegetación natural en los márgenes de los cultivos. Esto se debe principalmente a que la presencia de hábitats naturales favorece factores bióticos y abióticos que pueden afectar negativamente las plagas. Con base en lo anterior, esta investigación tuvo como objetivo evaluar y comparar el efecto de márgenes compuestos por plantaciones de palma de aceite y bosques de galería sobre el control biológico natural de <em>Spodoptera frugiperda </em>en cultivos de arroz. Para esto, se seleccionó un área de estudio en el piedemonte llanero colombiano (Villanueva, Casanare), compuesta por grandes extensiones de cultivos de arroz rodeados por plantaciones de palma de aceite y bosques de galería. Se evaluó la abundancia de <em>S. frugiperda </em>en estados de larva y adulto, el parasitismo de huevos y larvas, y la diversidad de enemigos naturales y de otros artrópodos. Se observó aumento en la presencia de insectos benéficos y disminución de la población de la plaga en los estadios de larva y adulto en cercanías a los márgenes. Se identificó la importancia de parasitoides como <em>Apanteles marginiventris </em>y depredadores, en especial correspondientes al orden Odonata para el control natural de <em>S. frugiperda</em>. Se encontró que tanto las plantaciones de palma de aceite como los bosques de galería promueven el control biológico natural de <em>S. frugiperda</em>; sin embargo, aspectos como la baja calidad del hábitat y la aplicación constante de insumos químicos afectaron los resultados significativamente<em>.</em></p><p class="Corpoica"><em> </em></p><p class="Corpoica"><strong>Incidence of the margins on the natural biological control of </strong><strong><em>Spodoptera frugiperda </em></strong><strong>(J. E. Smith) (Lepidoptera: Noctuidae) in rice crops</strong></p><p class="Corpoica">Multiple researches have shown the environmental, economic and productive benefits that can be generated when including natural vegetation in the margins of the crops. This happens thanks to the presence of natural habitats, which are the ones that promote biotic factors such as natural enemies and abiotic ones as temperature, humidity o rain that can affect negatively the pests. The objective of this research was to evaluate and compare the effect of other natural systems present at the same landscape such as crop of oil palm and gallery forests over the natural biological control of <em>Spodoptera frugiperda </em>in growing areas of rice. For this purpose, an area of study was selected at the Colombian plain foothills (Villanueva, Casanare), a place that is characterized for having big extensions of rice, surrounded by oil palms plantations and gallery forests. The abundance of <em>S. frugiperda </em>in the stages of larva and imago was evaluated, as well as the parasitism of eggs and larvae and the diversity of natural enemies and other arthropods. It was found that plantations of oil palm, as the gallery forests promote the natural biological control of <em>S. frugiperda </em>by increasing the diversity of the natural enemies and reduction of the pest population in the borders of the crop. The importance of parasitoids as <em>Apanteles marginiventris </em>and predators of the order Odonata in the control of <em>S. frugiperda </em>was identified. It is highlighted the importance to associate perennial crops as oil palm with transitory crops as rice in the planning of agroecosystems on the region and promote the conservation of gallery forest, as long as they can become key factors in the natural biological control of pests. Nevertheless, aspects as the low quality of the habitat and frequently use of chemical pesticides affected the results. </p>

European health systems face important challenges related to the sustainability of health care, both from an economic point of view and in relation to the quality of health services provided in terms of continuous improvement of effectiveness, safety, clinical and organisational appropriateness. The ability of EU Member States to continue to provide high quality care to all, whatever their biological and socio-cultural characteristics, depends on their health systems becoming more sustainable. Therefore, there is a need to strengthen health promotion and disease prevention, to invest in primary care systems, to move health care out of the hospital and into more accessible ambulatory and domestic care, and to develop integrated care practices. Starting from these premises, the aim of this paper is to present a narrative overview of the main aspects related to Gender Medicine and its evolution over time. Our critical overview is, therefore, aimed at providing a general picture of what has been developed by health systems on Gender Medicine, with a particular focus on the relationship between social sustainability and Gender Medicine. To achieve our goal, we carry out a systematic literature review in order to understand what has been developed so far in the area and to highlight the possible evolution of studies in the field and to strengthen the awareness of the importance of encouraging prevention, training and information programs shared with hospitals, institutions, health professionals and patient associations. To the best of the authors' knowledge, this is among the first studies that investigate through a systematic literature review the phenomenon of gender medicine, especially with reference to the sustainability of the health care system. Although our analysis needs further investigation, due to the fact that the topic is not yet fully mature, our initial and preliminary results underline the importance of further investigating gender diversity and assessing the possibility of promoting a clinical pathway to personalised treatment. In fact, only through a “gender medicine” approach it is possible to guarantee a real right to health and an effective personalisation of treatments, thus reinforcing the concept of patient focussed care and contributing to the sustainability of the whole health system.

This paper develops a theoretical critique of the varieties of capitalism (VoC) approach from the perspective of ideas sourced from Marxian political economy. In particular, the concept of economic surplus as formulated by Paul Baran is used to question the social ontology implicit in VoC, which, it is argued, is severely constrained by its imprecise definitions of both capitalism itself and capitalist diversity as a specific phenomenon. The result of these two failures is that VoC’s theoretical apparatus is unable to perceive the true significance of capitalist diversity, and is thus likewise incapable of telling us anything new about capitalism itself. In this way, key aspects of the institutionalist take on capitalist diversity are questioned, and an alternative analytical approach based on the labour theory of value is put forward.
