Résumé :

Abstract River water pollution has been reported globally. In suggestion to adapt sustainability approach, this study carry out to tests the structural equation model between sustainable development and water resources management in the Malacca River basin (Malaysia). The model consists of six latent constructs (anthropogenic activities; law, regulation and policy; land and water ecosystem; Malacca River; river water pollution; sustainability) and twenty four items based on 400 questionnaires which were completed and returned by the local residents of Malacca state. Selected study area is within Malacca River basin. The result show the Malacca River is influenced by water law-regulation-policy (β = 0.546, p < 0.001), anthropogenic activities (β = 0.145, p < 0.001), river water pollution (β = 0.142, p < 0.001), land and water ecosystem (β = 0.105, p < 0.01), as well as sustainable approach (β = 0.127, p < 0.5). It was found that a sustainable approach and water law-regulation-policy have a direct influence on anthropogenic activities, river water pollution, as well as the land and water ecosystem. In conclusion, this study suggests developing an earlier approach of the model involved with water resources management and sustainable development.

Résumé :

The concept of driving force-state-response (DSR) framework was used to identify and develop the assessment model of water-land environment carrying capacity (WLECC) for a river basin. The river basin water-land management (RBWLM) decision support system was developed, based on the assessment model of WLECC, as a decision making tool. The Chung-Kang river basin, located in northern Taiwan, was used as a case study to generate a sustainable water-land management strategy. This strategy simultaneously derives the optimal solutions for land use management, water demand allocation, and water quality management. Furthermore, the sustainable WLECC can also be obtained. The WLECC can be used as the area-based indicator of sustainability to accurately measure the progress towards sustainable development for a river basin.

Résumé :

Dynamic changes of landscape structure affect the abundance and distribution of organisms. Currently, changing land-use is one of the major forces altering ecosystem services in landscapes globally. Human activities are transforming land at a faster rate and greater extent than at any time in history. This is a perspective challenge for research in the field of emerging sustainability science. The human conversion of natural habitats and land use change is not only a local/regional phenomenon but can be considered as one of important global change drivers. Some of the impacts of global change on biodiversity can be studied only at the landscape scale, such as the climate change-induced shift of vegetation zones. A landscape perspective fosters a multi-scale approach to sustainable landscape management and landscape planning. Additionally, a landscape scale is very useful for the innovative application of the common management paradigm to multiple uses in agriculture, forestry and water resource management. The need for sustainable landscape management and planning is now obvious. Landscape conservation seems to be a new paradigm for the conservation of biodiversity. This Special Issue (SI) of the Sustainability journal is focused on building a bridge between scientific theory and the practice of landscape management and planning based on the application of sustainability as a key conceptual framework. Papers dealing with various theoretical studies and case studies of the best practice for sustainable landscape management and planning across diverse landscapes around the world are included.

Résumé :

Sustainability in terms of water management implies the study of all interrelated parameters (social, environmental, economic, engineering and political) in a comprehensive way. Although Greece is presented in the international rankings as a water-rich country, it has significant water problems due to its high temporal and spatial distribution of water resources and its unsustainable management practices characterized by a fragmented and sector-oriented water management system. This problem has been significantly improved by the adoption of the EU WFD and the development of management plans at the river basin scale. Nevertheless, because of the climate change effects, there is still a long way to go, and radical changes are needed in order to reach sustainability. Adaptation is a vital response toward sustainability. The Mygdonia agricultural basin is a case study of a highly negative water balance system that highlights the shortcomings of both water management and adaptation in Greece. Analysis of the hydrology of the basin, as well as the climate projections until 2100, revealed the urgent need for concerted action. A set of different development adaptation strategies was applied and assessed concerning their effectiveness. According to the outputs of this research, integrated watershed management is a prerequisite for a successful adaptation policy. Radical reform is needed in the agricultural sector by decreasing the agricultural land and changing crops. Demand management is the solution rather than focusing on supply options.

Résumé :

The sustainable management of Land-Water-Energy-Food (LWEF) nexus requires an environmental characterization that allows the comparison of complex interlinkages between nexus resources and livelihoods. This complexity makes this characterization difficult coupled with limited study in quantifying sustainability of LWEF nexus and its linkage with livelihood. Therefore, the present study aimed to investigate the link between sustainable LWEF nexus and livelihoods. In order to address the objective the proposed methodology starts with a detailed identification of LWEF and livelihood indicators which depicts well-defined, shared, and holistic methods to evaluate sustainability. With this we used analytical hierarchy process and pair wise comparison matrix in combination with weighting model. The result of composite LWEF nexus index was 0.083 representing, low sustainability. Besides, this composite index implies the use and management of LWEF nexus resources in the study area is very low, as the composite index approach to 1, the use and management of nexus resources are in a good condition which characterized by sustainability. This could be linked with nexus resources consumption, use, and management. From the analysis of the weight of land, water, energy and food nexus resources, the highest weight was observed for food. The focus of on food production only shows no clear synergy on provisioning, supporting or regulating nexus resources to address livelihoods. The result further showed that LWEF nexus resources have strong correlation with livelihoods. This was evidenced by social (r > 0.8, p < 0.01), natural (r > 0.3, p < 0.05) and physical (r > 0.6, p < 0.01) livelihood indicators showed strong positive correlation with LWEF nexus resources. Based on the finding of the study, it was observed that managing nexus resources not only provide a significant contribution to achieve sustainable LWEF nexus, but also be effective for enhancing livelihood through food security. This could be attained by strong evidence based policy to ensure sustainable use of nexus resources. The results provided by this study would serve as the foundation for future study, policy formulation and implementation.

Résumé :

Abstract Environmental Quality Guidelines for environmental sustainability are often lacking in many management or environmental policies. These are clear measures or indicators of the quality of the system. In Canada, national soil, water, tissue and sediment guidelines are developed to protect and sustain specific uses of land and water and provide direct measures of sustainability which can be incorporated into an overall ecosystem management framework. This short communication focusses on the use of pesticide Water Quality Guidelines for agricultural sustainability, especially with regard to surface and ground water contamination. Furthermore, this address introduces the new Canadian protocols for deriving Water Quality Guidelines for Irrigation and for Livestock Watering.

Résumé :

The current management of Lahumoko Watershed is still conventional. Mainly, in agricultural land management, the practices do not use the principles of soil and water conservation. This is not sufficient in supporting people’s lives so that the biological, physical, social, economic and institutional dimensions do not support the sustainability of the Lahumoko Watershed. This study aimed to analyze the sustainability and the factors that have multidimensional influence on the sustainability of the Lahumoko Watershed, North Buton Regency, Southeast Sulawesi, Indonesia. The method used was Rapid Appraisal for Watersheds, adopted from Rapid Appraisal for Fisheries using the Multi-Dimensional Scaling technique. The sustainability status of the Lahumoko Watershed management for the physical, economic and institutional dimensions were still less sustainable, while the biological and social dimensions were fairly sustainable. Some leverage attributes contributing to improving the sustainability of watershed management were patterns of agricultural crop cultivation, plant diversity in forest, management of protected organisms, river biota, management of forest cover, soil and water conservation technologies, agricultural infrastructure, runoff, sedimentation, water quality, education level, relationship pattern of the community, conflict status, land dependency, agricultural productivity, access to resources, access to markets, resource management planning and rule comprehensiveness for watershed management.

Résumé :

Effective and efficient water resources management is unquestionably required to meet the high demand of water to support rapid population growth and socio-economic expansion. The water supply availability is slowly decreased due to plantation land clearing, construction projects, and land-change activities in the watershed area. This study aimed to analyze the sustainability of irrigation management in Bali and outside of Bali (Bolaang Mongondow Regency, North Sulawesi). Primary and secondary data were employed in this study. In-depth interview and focus group discussion sessions conducted to collect the primary data. The literature review technique applied to gather secondary data to support the study result and discussion. We recruited the committee of subak, farmers, and stakeholders or policymakers from the Local Board of Agriculture and Public Works and Public Housing (sub-irrigation division) to participate in this study. Multi-Dimensional Scaling method employed to analyze the study data. Results revealed that the sustainability prospective of the irrigation system management in Mongondow was relatively weak, especially on the physical-ecological, infrastructure-technology, and policy-institutional dimensions. However, we noticed that the economy and social dimension of the watershed area was relatively sustainable. Contrary situations were found on Saba Watershed in Buleleng Regency, Bali Province. We found that the sustainability prospective on the physical-ecological and infrastructure-technology dimension was relatively weak. But the dimension of the economy, socio-cultural, and policy-institutional was adequately sustainable.

Résumé :

<p>With the rapid pace of urbanization and drastic transformation of economic form, Wuhan, a central city of China is facing serious inland inundation problems in recent decades. This study intends to alleviate Wuhan’s storm water management problems in a sustainable way and give suggestions as to the improvement of residential area storm water management and lakeside wetland protection. Based on the data provided by Geographical Information System, analysis is done to the land form of the whole city and the change of its lake areas, which evidently demonstrates the influences of economic development on the natural environment of the city and reveals the causes of the inundation problems. Taking the population growth, land use and climate change into consideration, this research argues that strategies such as green roof fostering, neighbor-hood water reuse and wetland conservation can make a difference in stormwater drainage and prevention of inland inundation in Wuhan.</p>

Résumé :

AbstractGroundwater sustainability initiatives, including sustainable yield and watershed policy protection policies, are growing globally in response to increasing demand for groundwater, coupled with concerns about the effects of climate and land-cover change on groundwater supply. Improved understanding of the impacts of watershed management on groundwater yields and management costs—particularly in the broader context of climate and land-cover change—is critical to inform these initiatives and facilitate integrated land and water management. This study develops a novel, spatially explicit groundwater hydrologic ecosystem services framework, which combines stakeholder-defined land-cover scenarios, sustainable yield estimation using a groundwater simulation optimization approach, and economic valuation, and applies it in the most heavily utilized aquifer Hawai‘i (USA). Sustainable yield estimates and resulting differences in replacement costs are estimated for six land-cover scenarios (with varying levels of urban development and watershed management) crossed with two water demand scenarios in a context of a dry future climate (Representative Concentration Pathway [RCP] 8.5 mid-century). Land-cover change is found to be an important, though less significant drive of changes in groundwater recharge than climate change. The degree of watershed protection, through preventing the spread of high-water-use, invasive plant species, is projected to be a much stronger land-cover signal than urban development. Specifically, full forest protection increases sustainable yield by 7–11% (30–45 million liters per day) and substantially decreases treatment costs compared with no forest protection. Collectively, this study demonstrates the hydrologic and economic value of watershed protection in a context of a dry future climate, providing insights for integrated land and water policy and management in Hawai‘i and other regions, particularly where species invasions threaten source watersheds.

Résumé :

With the growing population and climate change, increasing demands for water are intensifying competition between agricultural stakeholders. Since the mid-20th century, numerous crop models and modeling techniques have emerged for the quantitative assessment of cropping systems. This article introduces a collection of articles that explore current research in model applications for sustainable agricultural water use. The collection includes articles from model development to regional and field-scale applications addressing management effects, model uncertainty, irrigation decision support systems, and new methods for simulating salt balances. Further work is needed to integrate data science, modern sensor systems, and remote sensing technologies with the models in order to investigate the sustainability of agricultural systems in regions affected by land-use change and climate change.

Résumé :

In the last few decades, the increase in the world’s population has created a need to produce more food, generating, consequently, greater pressure on agricultural production. In addition, problems related to climate change, water scarcity or decreasing amounts of arable land have serious implications for farming sustainability. Weeds can affect food production in agricultural systems, decreasing the product quality and productivity due to the competition for natural resources. On the other hand, weeds can also be considered to be valuable indicators of biodiversity because of their role in providing ecosystem services. In this sense, there is a need to carry out an effective and sustainable weed management process, integrating the various control methods (i.e., cultural, mechanical and chemical) in a harmonious way, without harming the entire agrarian ecosystem. Thus, intensive mechanization and herbicide use should be avoided. Herbicide resistance in some weed biotypes is a major concern today and must be tackled. On the other hand, the recent development of weed control technologies can promote higher levels of food production, lower the amount of inputs needed and reduce environmental damage, invariably bringing us closer to more sustainable agricultural systems. In this paper, we review the most common conventional and non-conventional weed control strategies from a sustainability perspective, highlighting the application of the precision and automated weed control technologies associated with precision weed management (PWM).

Résumé :

This analysis suggests that a holistic or life-cycle approach be taken when assessing the long-term sustainability of sludge reuse options. Issues such as compliance with world best practice environmental/health standards, energyusage, greenhouse gas emissions, odour control and volume reduction must now be taken into account when assessing the long-term sustainability and public acceptability of the various management options. Four major criteria for the assessment of sludge reuse options are proposed and five management options are assessed using these criteria. The results indicate that traditional land application reuse options must be evaluated in more detail to confirm whether they offer a long-term sustainable management option. Newer thermal based management options may however provide long-term sustainable management options.

Résumé :

Research on sustainable transport and water projects, conducted in North America during 1999, identified four key considerations common to a number of projects. These four considerations are the pre-conditions necessary to achieve sustainability in a given location. These preconditions (BAPP) are boundary definition, administrative alignment, protection of non-urban lands, and the participation of all interested parties. This paper considers the perceived attitudes of various catchment stakeholders and focuses on planners and planning. The results of questionnaire surveys based on BAPP concepts suggest that local government is perceived as having the highest priority for protection of riparian lands and waterways (as individual Councils and Regional Organisations of Councils). Thus local government is the preferred arena for coordination, responsibility and jurisdiction of waterways and riparian land. The opportunity exists to examine the differing roles of local and state government. The paper concludes by outlining the implications of this research for land use planning and institutional structures in sustainable river management.

Résumé :

Abstract Crop intensification is required to meet the food demands of an increasing population. This paper presents data from three paired scaling-up initiatives to compare the benefits of landscape-based interventions over individual plot-level interventions using evidence generated in the Indian semi-arid tropics. A range of soil and water conservation interventions were implemented in a decentralized manner following the landscape-based approach. The plot-level approach focused only on balanced fertilizer application and improved crop cultivars while the landscape-based interventions primarily addressed moisture availability, which was the key to reducing risks of crop failure besides aiding productivity gain and enhanced land and water-use efficiency. These interventions have additionally harvested 50–150 mm of surface runoff and facilitated groundwater recharge in 550–800 mm rainfall zones. Individual plot-level interventions also improved the crop yield significantly over the control plots. However, crop intensification was not achieved due to limited moisture availability. Landscape-based interventions produced 100%–300% higher crop production per year, greater income generation (>100%), and improved water productivity. Landscape-based interventions were also found to be beneficial in terms of reducing soil loss by 75%–90% and improving base flow availability additionally by 20–75 d in a year compared to untreated watersheds. With increased moisture availability, fallow lands in respective watersheds have been utilized for cultivation, thereby enhancing crop intensification. The findings of the study provide critical insights into the design of approaches suitable for scaling-up projects in order to both create impact and target the United Nations Sustainable Development Goals.

Résumé :

Land degradation caused by improper land use management is a critical worldwide problem that has revived the issue of resources sustainability. Soil degradation, which involves physical, chemical, and biological degradation, is the key component of land degradation. Assessment of soil quality (SQ) indicators that distinguish soil degradation in different land use (LU) types is enviable to achieve sustainable land management strategies. The objective of this study was to assess the effects of land uses on soil quality indicators in the Geshy subcatchment of the Gojeb River Catchment, Omo-Gibe Basin, Ethiopia. The LU types identified for evaluation included natural forest, cultivation, and grazing lands. Accordingly, a total of 54 soil samples (three LU types × three slope classes (blocks) × three replications × two soil depths) were collected with an “X” plot design for data analysis. Statistical differences in SQ indicators were analyzed among LU types, slope classes, and soil depths and tested using univariate analysis of variance and Pearson’s correlation coefficient, following the general linear model. The results showed that a number of SQ indicators were significantly influenced by LU changes and soil depths. The sand, dry soil bulk densityρb, volumetric soil water contents (VSWC), total porosity, water infiltration rates, cumulative infiltration, and total nitrogen showed significant variations between the natural forest and the other LU types and soil depths (p<0.05). However, silt, clay, soil pH, SOC contents, carbon-to-nitrogen ratio, and available phosphorus did not show significant variations between LU types and soil depths (p>0.05). The overall qualities of the soils under the cultivation land were inferior in VSWC, TP, water infiltration rates, SOC contents, and TN soil attributes of the adjacent natural forest and grazing lands. The studied soils were found to be dominantly of clays with slightly acidic and low SOC contents and slow in their infiltration rate. Thus, integrated and sustainable land management, aimed at enhancing proper LU systems, is crucial for the sustainable ecosystem functioning and is the most effective way in reversing of soil quality deterioration.

Résumé :

SUMMARYThere is a need for coordinated research for the sustainable management of tropical peatland. Malaysia has 6% of global tropical peat by area and peatlands there are subject to land use change at an unprecedented rate. This paper describes a stakeholder engagement exercise that identified 95 priority research questions for peatland in Malaysia, organized into nine themes. Analysis revealed the need for fundamental scientific research, with strong representation across the themes of environmental change, ecosystem services, and conversion, disturbance and degradation. Considerable uncertainty remains about Malaysia's baseline conditions for peatland, including questions over total remaining area of peatland, water table depths, soil characteristics, hydrological function, biogeochemical processes and ecology. More applied and multidisciplinary studies involving researchers from the social sciences are required. The future sustainability of Malaysian peatland relies on coordinating research agendas via a ‘knowledge hub’ of researchers, strengthening the role of peatlands in land-use planning and development processes, stricter policy enforcement, and bridging the divide between national and provincial governance. Integration of the economic value of peatlands into existing planning regimes is also a stakeholder priority. Finally, current research needs to be better communicated for the benefit of the research community, for improved societal understanding and to inform policy processes.

Abstract The main goal of this article is to investigate sustainable urban development of the Central European city (Wrocław/Poland) through an environmental engineering application of SUDS (Sustainable Urban Drainage Systems) measures to managing stormwater in city sections with various land use in the same watershed area (the Ślęża River Valley). The author presents a study made in three different parts of the city (single housing district – Oporów, multihousing district – Nowy Dwór, public service district – Stadion), which were constructed in different historical periods. The analyses were supported by city masterplan, GIS software (Quantum GIS 1.7.4) and calculations made according to up-to-date specific regulations. They demonstrate the current sustainable stormwater management scenarios for areas of different land use, historical periods and function in the city. The proposed research method aims to compare sustainable urban development of the new urban district with the quarters, which had been built before the term “sustainability” became common in water and land development practice. The conducted study can be practically used as a supportive tool for urban planning authorities in Poland. The paper investigates a novel in the Polish realities method of assessment sustainability of the area through green infrastructure application in district scale.

Résumé :

Abstract. Developments such as climate change and a growing demand for drinking water threaten the sustainability of drinking water supply worldwide. To deal with this threat, adaptation of drinking water supply systems is imperative, not only on a global and national scale but particularly on a local scale. This investigation sought to establish characteristics that describe the sustainability of local drinking water supply. The hypothesis of this research was that sustainability characteristics depend on the context that is analysed, and therefore, a variety of cases must be analysed to reach a better understanding of the sustainability of drinking water supply in the Netherlands. Therefore, three divergent cases on drinking water supply in the Netherlands were analysed. One case related to a short-term development (2018 summer drought), and two concerned long-term phenomena (changes in water quality and growth in drinking water demand). We used an integrated systems approach, describing the local drinking water supply system in terms of hydrological, technical, and socio-economic characteristics that determine the sustainability of a local drinking water supply system. To gain a perspective on the case study findings that are broader than the Dutch context, the sustainability aspects identified were paired with global aspects concerning sustainable drinking water supply. This resulted in the following set of hydrological, technical, and socio-economic sustainability characteristics: (1) water quality, water resource availability, and impact of drinking water abstraction; (2) reliability and resilience of the technical system and energy use and environmental impact; (3) drinking water availability, water governance, and land and water use. Elaboration of these sustainability characteristics and criteria into a sustainability assessment can provide information on the challenges and trade-offs inherent in the sustainable development and management of a local drinking water supply system.

Résumé :

Agricultural land expansion is a solution to address global food security challenges in the context of climate change. However, the sustainability of expansion in arid countries is difficult because of scarce surface water resources, groundwater salinity, and the health of salt-affected soil. Developing expansion and sustainability plans for agriculture requires systems thinking, considering the complex feedback interactions between saline groundwater, salt-affected soil, plant growth, freshwater mixing with saline groundwater, irrigation systems, and the application of soil amendments to alleviate the salinity impacts. This study presents an extensive literature review on the effects of salinity on soil and plant health, the constraints and opportunities for sustainable agriculture in Egypt, and a systems thinking approach to the feedback interactions between saline water, salt-affected soil, and the application of soil amendments to achieve required crop yields. Insights and strategies are discussed, including a system-dynamics-based decision model, irrigation systems with diversified and decentralized water sources, urban water demand management, energy availability, smart irrigation systems, and active participation of stakeholders to achieve sustainable agriculture under climate and socioeconomic changes. The insights are expected to encourage stakeholders and academic communities in the water, agriculture, and related food security sectors to develop a quantitative and systematic decision-making framework for sustainable agriculture systems in arid regions.

Sustainable land use and rational soil management, including an up-to-date soil moisture control requires continuous actions. This permanent control may prevent, eliminate or at least reduce undesirable soil processes and their harmful economical/ecological/environmental/social consequences; utilizing the unique soil characteristic, resilience, may satisfy the conditions for the “quality maintenance” of this “conditionally renewable” natural resource. Control can be efficient only on the basis of comprehensive risk assessment, impact analysis and exact prognosis. These have to be the main research priorities! The successful prevention, elimination or moderation of undesirable soil degradation processes and extreme moisture regimes can be efficient only in a well-coordinated multidisciplinary international cooperation in the Carpathian Basin. The realization of the sustainability concept in the rational land use and soil management gives reality for a better life: healthy, good quality food, clean water and pleasant environment.

Résumé :

Climate change forcings are having significant impacts in coastal Louisiana today and increasingly affect the future of New Orleans, a deltaic city mostly below sea level, which depends on levee and pumps to protect from a host of water-related threats. Precipitation has increased in the Mississippi River basin generally, increasing runoff, so that in recent years the Mississippi River has been above flood stage for longer periods of time both earlier and later in the year, increasing the likelihood that hurricane surge, traditionally confined to summer and fall, may compound effects of prolonged high water on river levees. The Bonnet Carré Spillway, just upstream of New Orleans has been operated more often and for longer periods of time in recent years than ever before in its nearly 100-year history. Because all rain that falls within the city must be pumped out, residents have been exposed to interior flooding more frequently as high-intensity precipitation events can occur in any season. A sustainable path for New Orleans should involve elevating people and sensitive infrastructure above flood levels, raising some land levels, and creating water storage areas within the city. Management of the lower Mississippi River in the future must include consideration that the river will exceed its design capacity on a regular basis. The river must also be used to restore coastal wetlands through the use of diversions, which will also relieve pressure on levees.

Résumé :

Recognition of sustainability issues around water resource consumption is gaining traction under global warming and land utilization complexities. These concerns increase the challenge of gaining an appropriate comprehension of the anthropogenic activities and natural processes, as well as how they influence the quality of surface water and groundwater systems. The characteristics of water resources cause difficulties in the comprehensive assessment regarding the source types, pathways, and pollutants behaviors. As the behavior and prediction of widely known contaminants in the water resources remain challenging, some new issues have developed regarding heavy metal pollutants. The main aim of this review is to focus on certain essential pollutants’ discharge from anthropogenic activities categorized based on land-use sectors such as industrial applications (solid/liquid wastes, chemical compounds, mining activities, spills, and leaks), urban development (municipal wastes, land use practices, and others), and agricultural practices (pesticides and fertilizers). Further, important pollutants released from natural processes classified based on climate change, natural disasters, geological factors, soil/matrix, and hyporheic exchange in the aquatic environment, are also discussed. Moreover, this study addresses the major inorganic substances (nitrogen, fluoride, and heavy metals concentrations). This study also emphasizes the necessity of transdisciplinary research and cross-border communication to achieve sustainable water quality using sound science, adaptable legislation, and management systems.

Résumé :

South Tarawa is a town on an isolated Pacific atoll of approximately 46,000 people, with absolute water scarcity, poor water safety and consequently water-related problems. It relies on shallow groundwater, with contributions from rainwater tanks and desalination. Due to a combination of factors such as small scale, limited human resources, system complexity, isolation and lack of financial resources, water management capacity is inadequate. Sustainability of groundwater resources is also uncertain and there are indications that groundwater has been extracted above the sustainable pumping rates. Social complexity is highlighted by the resistance from traditional landowners to the attempts to deal with the supply-side deficit through establishment of new infiltration galleries. In this paper, issues relating to water management in South Tarawa are reviewed. This follows on to an exploration of possible strategies to improve the existing situation. This research forms an empirical building block in the foundation of a larger study, aiming at developing a framework for strategic and adaptive small town water management. In particular, the larger study explores the options and viability of co-management of water and land resources in small scale urban areas as an alternative to traditional urban management approaches.

Résumé :

Of the renewable resources of The Biosphere, agricultural land, including its water resources, is very high among the most important, because it is elemental for human and domestic-animal life. The stability and sustained fertility of the soil largely depend on both prevailing soil–climate conditions and on anthropogenic influences.There are strict limits to the human interference which soil substrates, ground, soil, and surface water, flora, fauna, and microorganisms, can tolerate under moderate, let alone subtropical and tropical, soil–climate conditions. Economic, social, and aesthetic, yield of agricultural resources is limited even where economically and technically optimal use is made of capital and labour. A ‘maximum sustainable yield’ varies as a function of the soil–climate location, the established land-use system, and the technology applied, but only as long as this yield is not exceeded is the enduring availability of the resource ensured.With the demand for land and energy to produce food and agricultural raw materials rising throughout the world, per caput food production continuing to fall (especially in Africa), and the cultivated area per caput declining worldwide, the urgent question for the long term is how to preserve the natural resources of water, soil, and vegetation cover, and how to arrest desertification, deforestation, salinization, soil degradation, and soil erosion.These reflections centre on the call for farming systems which are suited to given locations and do no harm to the environment, and also for sustainability of agricultural production—two aspects which have been badly neglected in the past. The necessary simultaneous tasks of developing farming systems and preserving resources, can be tackled only in relation to specific locations and in a conducive development ‘climate’, where appropriate general conditions prevail. As a rule, the microeconomic development options for coping with these tasks can be improved only at a supra-farm and community level, and require new, environmentally oriented national agricultural and rural development policies.

Résumé :

A prerequisite for achieving the objectives of sustainable development is knowledge of the nature, extent, geographical distribution, along with the potentials and limits of natural resources. The mapping, monitoring, measuring, and management of many elements of the built, natural, and biophysical environments are all made possible through satellite remote sensing. Remote sensing is a crucial tool for advancing solutions and offers useful insights into urgent environmental concerns. Thus, data collection for efficient resource management in Ghana has shown to be greatly aided by remote sensing, which may also be used for environmental monitoring and management. Because of this, it is crucial for remote sensing technology to progress in order to acquire data more effectively and efficiently, which helps with rapid change detection, sustainable environmental management, and sustainability. This review's goal was to provide a thorough analysis of the literature on Ghana's use of remote sensing for environmental management and sustainability. Wiley, Taylor & Francis, Science Direct (Elsevier), and Scopus (Elsevier) were a few of the databases used for the review. The findings indicate that there are numerous remote sensing applications for sustainable environmental management in Ghana, including environmental impact assessments of various projects, analyses of changes in land use and land cover, mapping of watersheds and hydrologic features, estimation of soil loss, management of water resources, management of forestry resources, and management of natural disasters. The outcomes also demonstrate that natural, biophysical, and constructed ecosystems might be appropriately monitored and sustainably managed for the benefit of both the present and future generations with the use of remote sensing technology. Governments, municipal managers, environmentalists, and planners may develop useful plans and strategies for sustainable development and effective environmental management with the aid of the information supplied by remote sensing.

Résumé :

Organic waste management is a growing issue due to the unsustainable practices of its disposal. Sewage treatment plants are designed to treat wastewater to produce a safe effluent. However, one of the by-products, the sewage sludge which is disposed off in landfill or used as fertilizer in agricultural operation is high in pathogens. Sustainability can be achieved by Vermicomposting of organic matter which involves accelerated cycling of nutrients though a closed cycle whereby waste products are put to productive end use. Vermicomposting and vermifiltration are natural waste management processes relying on the use of worms to convert organic wastes to stable soil enriching compounds. Domestic wastewater management can be accommodated through these processes in a sustainable manner. A considerable reduction in pathogens has been noticed in the end product to a level that it can be safely applied to land. This paper provides an overview of the system characteristics of management systems utilising vermiculture, to manage wastewater. The process can be used in a small scale for household waste treatment to rural or urban waste management.

Résumé :

Universitas Sebelas Maret (UNS) is the biggest university in Surakarta Central Java Indonesia, which was established on March 11th, 1976 through Presidential Decree No. 10 of 1976. Commitmen of UNS toward Green Campus began in 2012 by Rector Decree 7nd of August 2012. Land size of UNS, whis is only 60 ha becomes constraints in development of Green Campus Initiatives. In 2030 agenda of Sustainable Development Goals gives attention to huge increased of urbanization thus cities and human settlements face the problems of high density, economies of agglomeration link economy, energy, environment, science, technology and social and economic output [2]. The Problem of Water and Sanitation becomes big issues of Sustainable Development Goals (SDGs), which is stated in the Goal 6 out of 17 Goals. Goal 6 not only addresses Clean water sanitation and health but also quality and sustainability of water resources all over the world. Universitas Sebelas Maret is one of Campus in Indonesia, which has awareness toward water and sanitation, especially related to the problem of waste. Liquid waste has become problems for a long time in UNS, when domestic liquid waste has come from residential areas surrounding campus passed through the lake in campus before finally flowing to Bengawan Solo River. This causes euthropication and sedimentation of the lake of UNS, which had impact on extremelly decreased the function of the pond estetically and functionally. By partnership with the Ministry of Public Works anad Spatial Planning in 2017, UNS has built Integrated Waste Water Treatment, which treats domestic liquid waste from residential area surrounding campus and internal campus becomes recycled clean water. In spite of that, UNS also treats organic waste of fall leafs through composting units and manages chemical hazardous waste according to the Indonesian regulation issued by Ministry of Environment. Several efforts of UNS related to Waste Management have contribution to achieving SDGs especially Goal 6: ensure availability and sustainable management of water a sanitation for all [2]. This contributes for improving water quality by reducing pollutions, dumping, minimizing chemical hazardous waste, increasing recycled and safe reuse of water on Campus.

Résumé :

The Sustainable Development Goals (SDGs) can be grouped into three domains, the environmental domain, the social domain and the economic domain. These different layers influence each other; hence sustainable progress in the economic layer cannot be achieved without good progress in the two other layers. To achieve the SDGs, transitions in the current system are needed and actions should be taken that support transitions and contribute to short term needs and long term (global) goals. Therefore, it is necessary to have knowledge of transitions and understand the different phases of transition. In this paper we discuss the key role of the soil-water system in these transitions and the achievement of the SDGs by 2030. The increasing pressure on land calls for multi-use of land and for the restoration of degraded land. Healthy soils and healthy land are the basic conditions for the successful implementation and realization of the SDGs. To enable a sustainable management of the soil and water system a transition approach is a prerequisite. In the X-curve used to describe transitions, soil and land stakeholders are given a framework, which provides perspective for action, specifically for science and governance stakeholders in each phase of the transition. This framework can provide the required intensive guidance to (1) analyze the impact of provided incentives, (2) identify new reference points in the transition and (3) stimulate transition catalysts, and (iv) innovate by testing cutting edge policy instruments in close cooperation with society. The key to make the necessary transitions and realize the SDGs by 2030 lies in the intensive guidance to combining initiatives, steering knowledge flows and continuously assessing the stage of the transition, in order to plan specific steps needed to progress in the transition framework. Both scientist and policy makers have an important role in this guidance.

Résumé :

How will we be fed in the future? Without a doubt, the recent development has to undergo a change, to stick to the aims of sustainable development. Modern agriculture is in the compulsion of its consumers’ behaviour and the constantly growing amount of food required for feeding the world population. This nutrition is taken into individual responsibility, but to be able to make decisions regarding sustainable nutrition, educational work is required. By determining the environmental impact of different ingredients, Burger.i.doo contributes to the Education of Sustainable Nutrition and empowers its gamers to gain and extend their knowledge about the consumption of capabilities. It is designed for students aged 14 to 18. The aim is to create the most sustainable burger, which is measured in five categories: greenhouse gas emission, water consumption, land use, price and taste, by comparing the different categories of vegan, vegetarian, pescetarian and different meat options of burgers. To evaluate the impact of the game, a survey was conducted. It shows that the key targets of the construction of the game are fulfilled: the gamers had fun, learned about the impact of food on the environment and the game had a positive influence on their environmental consciousness.

Résumé :

Nuclear science and technology (NST) offers a multitude of applications and tools and has a high level of regulation. However, its contribution to the achievement of global development goals is still incipient. Although its application is directly related to many fields, especially sustainability, the current literature does not relate it to socio-environmental issues, hindering the adoption of public policies based on isotopic and nuclear solutions. In large and megacities, the promotion of human well-being and the conservation of ecosystems are urgent global challenges, especially as a function of the growing expansion of land use modification, water scarcity, and climate change. The relationship between society and NST is addressed in this study, which aims to show how and in what ways the emerging and innovative nuclear and isotopic solutions contribute to the urban dimension of the United Nations 2030 Agenda, expressed by SDG 11 (Sustainable Cities and Communities), and its connection to land, water, and climate change in cities. This gap in knowledge compromises the targeting of resources to improve NST as a development strategy. Demystifying NST and increasing collaboration between ecosystem services and other issues related to sustainability in cities are key to implementing global development policies, especially at the local governance level.

Résumé :

The article discusses key aspects to be considered for the orientation of sustainable resource policies. Resource management at the local scale needs to be supplemented by governmental action in order to adjust production and consumption toward acceptable levels of global resource use. What is acceptable is being informed by scientific findings on environmental degradation and relevant cause–effect relationships. However, the desired state of the environment, the tolerable level of uncertainties about environmental impacts, risks of societal conflicts, and ethical considerations all involve normative considerations. Policy decisions for sustainable global resource use must be taken on the basis of imperfect information. A wider systems perspective, longer time horizon, and broader involvement of available knowledge could provide a sufficiently valid basis to derive directionally safe targets. Possible proxy targets for global biotic and abiotic resource use, considering land, biodiversity, and water issues, are presented on a per-person basis for 2050 for further discussion and research. These values could be used to assess the resource footprints of countries with regard to sustainability, providing orientation for governments and industry.

Résumé :

Abstract In Uganda, upgrading smallholder agriculture is a necessary step to achieve the interlinked sustainable development goals of hunger eradication, poverty reduction and land degradation neutrality. However, targeting the right restoration practices and estimate their cost-benefit at the national scale is difficult given the highly contextual nature of restoration practices and the diversity of small-scale interventions to be adopted. By analysing the context-specific outcomes of 82 successful case studies on different sustainable land and water management (SLWM) in Uganda, we estimated that out-scaling of existing successful practices to 75% of agricultural land would require a one-time investment of US$ 4.4 billion from smallholders. Our results show that, besides the many social and environmental benefit commonly associated to SLWM, a wide outscale of SLWM could generate US$ 4.7 billion every year, once the practices are fully operational. Our context-specific estimates highlight the profitability of investing in smallholder farming to achieve the sustainable development goals in Uganda, with geographical differences coming from specific social-ecological conditions. This study can guide sustainable intensification development by targeting the most suitable SLWM practices and plan for adequate financial support from government, investors and international development aids to smallholder farming.

The rapid appraisal for program modified from rapid appraisal for fisheries program using the multidimensional scaling (MDS) method was used as the analytical instrument. MDS ordination analysis results showed the sustainability index value of each dimension, namely ecology (37.30), economic (40.90), social (31.74), and technology (34.33) were categorized as less sustainable with an average index value of all dimensions was 36.07. The leverage analysis visualizes that 9 out of 17 attributes has shown to be sensitive attributes that affect the business sustainability of ornamental plant in Makassar, namely frequency of crop waste management, water sources, utilization of plant waste, market scale, profitability, business land status, company registration certificate, use of modern technology, and frequency of environmentally friendly technology usage. Government should provide special business zones for ornamental plant so that all ornamental plant farmer in Makassar can be grouped into one zone. Furthermore, it can increase gross regional domestic product, employment opportunities, and opening up opportunities of other industrial sectors growth.

Résumé :

Understanding farm-level efficiencies of resource use is critical in comparisons of the sustainability of aquaculture production systems. We developed a set of practical resource-use efficiency metrics to calculate and compare resource-use efficiency with resource-cost efficiency across major species and production systems in US aquaculture. Results showed that no one production system used all resources most efficiently. Intensive pond production of channel catfish Ictalurus punctatus demonstrated the greatest efficiency in the use of water, energy, labor, management, and capital resources, while RAS production was most efficient in terms of land and feed use. Among the wide array of pond scenarios examined, more intensive scenarios generally were more efficient in terms of several metrics, but economic sustainability also depends upon business models that effectively meet differing demand requirements of customers. Thus, less intensive production systems were economically sustainable in areas with relatively abundant land and water resources available at lower cost. Labor efficiencies varied widely across scenarios analyzed. Given increasing concerns related to the availability of labor for aquaculture farming in the USA, greater attention to the efficiency of labor on farms is warranted. The metrics used were aligned with common farm management tools (e.g. enterprise budgets) that allow for ease of use by farms and researchers to assess effects on comparative resource-use efficiencies of new farming practices and technologies under development.

Résumé :

AbstractThe agricultural community is confronted with dual challenges; increasing production of nutritionally dense food and decreasing the impacts of these crop production systems on the land, water, and climate. Control of plant pathogens will figure prominently in meeting these challenges as plant diseases cause significant yield and economic losses to crops responsible for feeding a large portion of the world population. New approaches and technologies to enhance sustainability of crop production systems and, importantly, plant disease control need to be developed and adopted. By leveraging advanced geoinformatic techniques, advances in computing and sensing infrastructure (e.g., cloud-based, big data-driven applications) will aid in the monitoring and management of pesticides and biologicals, such as cover crops and beneficial microbes, to reduce the impact of plant disease control and cropping systems on the environment. This includes geospatial tools being developed to aid the farmer in managing cropping system and disease management strategies that are more sustainable but increasingly complex. Geoinformatics and cloud-based, big data-driven applications are also being enlisted to speed up crop germplasm improvement; crop germplasm that has enhanced tolerance to pathogens and abiotic stress and is in tune with different cropping systems and environmental conditions is needed. Finally, advanced geoinformatic techniques and advances in computing infrastructure allow a more collaborative framework amongst scientists, policymakers, and the agricultural community to speed the development, transfer, and adoption of these sustainable technologies.

Résumé :

The study of runoff under the influence of human activities is a research hot spot in the field of water science. Land-use change is one of the main forms of human activities and it is also the major driver of changes to the runoff process. As for the relationship between land use and the runoff process, runoff yield theories pointed out that the runoff yield capacity is spatially heterogeneous. The present work hypothesizes that the distribution of the runoff yield can be divided by land use, which is, areas with the same land-use type are similar in runoff yield, while areas of different land uses are significantly different. To prove it, we proposed a land-use-based framework for runoff yield calculations based on a conceptual rainfall–runoff model, the Xin’anjiang (XAJ) model. Based on the framework, the modified land-use-based Xin’anjiang (L-XAJ) model was constructed by replacing the yielding area (f/F) in the water storage capacity curve of the XAJ model with the area ratio of different land-use types (L/F; L is the area of specific land-use types, F is the whole basin area). The L-XAJ model was then applied to the typical cultivated–urban binary land-use-type basin (Taipingchi basin) to evaluate its performance. Results showed great success of the L-XAJ model, which demonstrated the area ratio of different land-use types can represent the corresponding yielding area in the XAJ model. The L-XAJ model enhanced the physical meaning of the runoff generation in the XAJ model and was expected to be used in the sustainable development of basin water resources.

Résumé :

The paper aims to understand the combination of biomimicry and the BREEAM category of energy to identify innovative solutions for sustainable architecture and sustainable urbanism. It purposes to find similarities between biomimicry and the BREEAM category of energy by selecting and analyzing literature. The study aims to indicate potential applications of biomimicry, and the BREEAM category of energy focused on building design. The main question of this research is to discover how biomimicry and the BREEAM category of energy could combine to identify innovative solutions to address sustainable architecture and sustainable urbanism? The research required a systematic literature review for identifying, collecting, and analyzing relevant studies. JSTOR, Science Direct, and Microsoft Academic were used as repositories and led to the identification of 3855 studies. After screening, eligibility, and inclusion, 39 studies were included in the systematic literature review. More studies discussed sustainable architecture and required classification through subthemes: biomimetic design and associated principles; building skin; integrated framework; designing with BREEAM. The paper provides insight into biomimetic design approaches and energy management combining to ensure sustainability ranging from a building to an urban environment. The chosen research method causes the research results to lack generalizability since it does not associate with other BREEAM categories such as health and wellbeing, innovation, land use, materials, management, pollution, transport, waste, and water. The research fulfills the need to study the combination of biomimicry and one of the BREEAM categories to identify innovative solutions for sustainable architecture and sustainable urbanism.

Résumé :

Human activities mostly impact the trend and direction of rainwater, groundwater, and other river basin resources in the watershed in Africa. These activities alter river flows and the quality of usable water supplies at both highlands and lowlands. A watershed is indeed a conserved area of land that collects rain, sleet and snow, and empties or penetrates groundwater sources. The act of managing the activities around the watershed is integrated watershed management, which considers the social, economic, and environmental issues in tandem with the human, institutional, natural, and sustainability systems, which are the key drivers as identified in this study, as well as community interests and participation, to manage groundwater resources sustainably. These watersheds, river basins, and groundwater resources provide important services for communities and biodiversity. This paper reveals that the best way to protect groundwater resources is on a watershed basis using sustainable management measures. This technique enables us to handle a variety of concerns and objectives while also allowing us to plan in a complicated and uncertain environment. Sustaining a regional and sub-regional watershed involves cooperation and participation from a wide range of community interests and water users, including municipalities, companies, people, agencies, and landowners, for stakeholders’ input to be successful. All of the strategies and plans are produced with regard to one another, as well as the overall conditions of the watershed, local land uses, and specific regional transboundary issues.

Résumé :

Sustainability of Vietnam agriculture value chain will be dependent on various factors such as skills and experience of farmers, advanced technology, agricultural engineering, standards and models such as VIETGAP or GLOBAL GAP, etc. The role is still important, but Vietnam's agricultural production still has many Weakness points compared to other countries in the region when comparing resource use efficiency (land, water and labor). As a result, the efficiency of agricultural production tends to decrease recently. Specifically, the growth in average agricultural labor productivity annual rate of Vietnam also decreased correspondingly from 2.7% in the period 1990-1999 to 2.5% in the period 2000-2013 (World Bank, 2016). In Vietnam, we will evaluate the effectiveness of VIETGAP and GLOBAL GAP models, principles and standards applying in Vietnam agriculture value chain in a specific case study. The research results show a strict condition for applying VIETGAP and GLOBAL GAP for better quality in agriculture, including: Conditions for soil, irrigation water, fertilizers, pest control, etc. Last but not least, we also use an econometric model to measure impacts of multi macro factors on lychee price in Vietnam market over past years 2014-2019. Regression results show that we need to control inflation at low level, stable GDP growth and trade balance and exchange rate to stabilize lychee price. The research findings are of value to policy makers, farmers and investors in making decisions to invest for sustainability of Vietnam agriculture value chain. We will also make suggestions for commercial bank system in agriculture sector development.

Résumé :

Climate and land use changes have substantially affected hydrologic cycles and increased the risk of drought. Reservoirs are one of the important means to provide resilience against hydrologic variability and achieve sustainable water management. Therefore, adaptive reservoir operating rules are needed to mitigate their adverse effects. In this study, the Hanjiang River Basin in southeast China was selected as the study area. Future climate and land use projections were produced by the Delta method and CA-Markov model, respectively. Future climate forcings and land use patterns were then incorporated into a distributed hydrologic model to evaluate river flow regime shifts. Results revealed that climate and land use changes may lead to severe drought conditions in the future. Lower flows are shown to be more sensitive to environmental changes and a decline of monthly flows could reach up to nearly 30% in the dry season. To address the threat of increasing drought uncertainties in the water supply system, the aggregation-decomposition method incorporated with hedging rules was applied to guide the multi-reservoir operation. Parameters of optimal hedging rules were obtained by a multi-objective optimization algorithm. The performance of hedging rules was evaluated by comparison to standard operating policies and conventional operating rules with respect to reliability, resiliency, vulnerability, and sustainability indices. Results showed that the multi-reservoir system guided by hedging rules can be more adaptive to the environmental changes.

Résumé :

Urban India produced around 62 MT of municipal solid waste (MSW) (450 gcapita-1day-1) in 2015. Approximately 82% of the generated MSW was collected and only 28% of the collected waste was treated and the remaining 72% was openly dumped. Open dumping is the popular MSW disposal practice in India due to budget constraints and lack of technological advancement. Open dumpsites are considered a potential threat to environment and human health since they contaminate land and water resources during migration of leachate and create air pollution in terms of release of landfill gases (LFGs) with high percentages of greenhouse gases and thus contribute to climate change. It also consumes valuable land which could be converted into revenue generated assets. In 2011, India needed 380 km2 areas for waste disposal which will be 660 km2 by 2030. In 2016, the India Government has amended the Solid Waste Management Rules (SWM) for effective and proper management of MSW and reclaim the large old dumps by closure and recommend rehabilitate by a feasible solution in terms of reduction of waste by biomining. Biomining concept is an innovative, environmentally acceptable, economically and practically feasible and rapid measure to remediate the old open landfill site to successfully bring to zero emission of LFGs and leachate and also reclaim the land reusability and zero maintenance. In this study, the concept and utility of biomining as a key part of sustainable landfill management especially for the rehabilitation of MSW dumpsites in different megacities in India have been discussed.

Résumé :

The fisheries sector significantly contributes to global food security, nutrition, and livelihood of people. Its importance for economic benefits, healthy diets, and nutrition, and achieving sustainable food systems is highlighted by several Sustainable Development Goals (SDGs), i.e., SDG 1 (No Poverty), SDG 2 (Zero Hunger), and SDG 14 (Life Below Water). However, due to unprecedented population levels, the contribution of the fisheries sector to fulfills these roles is challenging, particularly given additional concerns regarding environmental well-being and sustainability. From this perspective, this study aims to identify the links and trade-offs between the development of this sector and the environmental sustainability in Thailand via a critical analysis of their trends, current ecological impacts, and more importantly, their contributions to several individual SDGs. A time-series of Thailand’s fisheries production from 1995 to 2015 indicates a recent reduction from around 3.0 million tons in 1995 to 1.5 million tons in 2015 of wild fish and shellfish from marine and freshwater habitats. The maximum sustainable yield of these species has been exceeded. Conversely, Thailand’s aquaculture production has continued to grow over the last decade, resulting in a reduction of mangrove forest area, wild fish stocks, and water quality. While capture fisheries and aquaculture production significantly contribute to several SDG targets, there are potential trade-offs between their development and the achievement of SDGs within the planet dimension, i.e., SDG 6 (Clean Water and Sanitation), SDG 12 (Responsible Consumption and Production), SDG 13 (Climate Action), SDG 14, and SDG 15 (Life on Land). On the one hand, the mitigation of overfishing will be beneficial for the targets of SDG 14, leading to more sustainable resource management. On the other hand, it might cause a decrease in the volume of marine catches and economic and social profits. We conclude that the SDGs can serve as a framework for both policymakers and industrial workers to monitor and compromise on regulations that will optimize productivity in the context of sustainable development.
