Résumé :

The problem of creating a methodology for integrated management of land and water resources as one of the important components of the methodology of sustainable development is considered. The existing methodological approaches to integrated land and water resources management are analyzed and their main shortcomings are revealed. The methodology of integrated land and water resources management is based on contour-reclamation and functional-cost management principles. Analogs of the first, contour-ameliorative, principle are chosen the basic provisions of contour-ameliorative agriculture and the basin principle of water resources management. This principle consists of the contour principle, according to which integrated land management is carried out in the contours of certain land plots, and water resources – in the contours of river basins or sub-basins, and reclamation principle, according to which integrated management is carried out by developing and implementing measures to improve social, environmental and economic indicators of land and water use, using the term "reclamation" in a broader sense (Latin melioratio – improvement). The functional-cost principle is chosen as the main principle of the methodology of integrated resource management. The foundations of scientific and methodological tools of integrated management of land and water resources in the form of algorithms of local, zonal and regional integrated management of land and water resources are laid. The obtained research results are recommended for research institutions, design and environmental organizations, as well as specialists who deal with the problem of identifying and implementing strategic priorities for sustainable development of land and water resources.

Résumé :

Sustainable land management requires that water and matter (nutrients and base cations) are efficiently recycled within ecosystems so that irreversible losses of matter from topsoils are minimised. Matter losses are connected to water flow. The division of water into evapotranspiration that is loss-free, and seepage to groundwater or surface water flow that both carry material losses, is decisive in determining total losses of dissolved matter in a given catchment. Investigations of areal matter losses confirmed the instrumental role of vegetation cover. Areal matter losses measured in agricultural catchments in Germany were on average between 1–1.5 tons of dissolved matter per ha per year, i.e. some 50 to 100 times higher than those from unmanaged land in a virgin forest. Such high losses continuously reduce soil fertility and can hardly be compensated by fertilisation. Some suggestions on how to achieve sustainable management of agricultural land and maintain high soil fertility are presented – the priority is to close water and matter cycles through the incorporation of more natural vegetation cover into our landscapes and to restore the energy-dissipative properties of ecosystems.

Résumé :

This paper starts from the fact that spatial and urban planning promote rational land use planning and express interests in the sustainable development of land, water and related resources and infrastructure. The authors here look for sustainable land use planning solutions in the domain of water management within the spatial plans. A starting point of this paper is the fact that integration of water management issues (i.e. drinking water management) into land use planning is essential in achieving sustainable development. Considering this, the paper focuses on analysis of land use planning solutions given within three spatial plans that include areas of water supply reservoirs. The authors give an analysis of the set of measures prescribed by zoning ordinances within spatial plans concerning water protection and protection from water (i.e. flood water evacuation). The authors conclude that analyzed spatial planning documents give sustainable land use solutions, since land use planning, through the zoning, represent a starting point in water protection.Keywords: Spatial Planning, Sustainable Land Use, Water Management, Water Reservoirs, Serbia

Résumé :

Rural environmental protection has received increasing attention in recent years. The economic development and population growth of rural areas results in many problems, such as environmental pollution, land degradation, resource depletion, biodiversity loss, income loss, and public health risks. Although much progress has been made, many major challenges to rural environmental management remain to be addressed. The question of how to deal with these problems through sustainable approaches has become an urgent issue in rural areas. This Special Issue, “Rural Sustainable Environmental Management”, was dedicated to the perception of rural, sustainable environmental management based on the integration of economic, environmental, and social considerations. The Special Issue covered the topics about the rural land management and planning, sustainable rural water resources management, integrated simulation and optimization, rural environmental risk assessment and vulnerability analysis, rural water and wastewater treatment, rural environmental policy analysis, rural ecosystem protection and biodiversity recovery, and the characterization of emerging rural environmental problems and related solutions. A total of 24 high-quality papers were accepted after strict and rigorous review. These accepted papers focused on various perspectives of rural sustainable environmental management.

Résumé :

Human uses of land and water are directly linked and must, therefore, be managed with each other in mind. This paper puts forward an approach for integrating sustainable water resource management into local land use decision-making in the Potomac basin. The approach includes developing a clear understanding of the current regulatory, programmatic, and financial approaches to land use management; identifying opportunities from innovation; and developing a flexible, stakeholder-based framework for moving forward. Four opportunities for innovation were identified in the Potomac basin utilizing this approach, including enhancing coordination and access to information, promoting incentives to achieve desired outcomes, encouraging and promoting innovation, and integrating programs to achieve multiple objectives. The successful integration of land and water decision-making requires a sustained, long-term commitment to improvement rather than a one-time fix mentality. Initial steps for implementation include identifying and engaging diverse partners, as well as establishing channels for information dissemination. The lessons learned from this work may prove valuable to decision-makers in other regions to holistically manage diverse land and water resources.

Résumé :

Population growth, rapid urbanization, changing diets, and economic development are among the major driving factors of increased demand for water, food and land. In this study, an integrated model was developed for managing land-water-food nexus. A water footprint-based fuzzy fractional programming (WFFP) is developed for optimizing resource allocations toward sustainable food and water security under the agricultural, food, socioeconomic, and natural resource constraints. By calculating the blue and green water footprint of each crop, optimum food requirements were converted into optimal cropping options. The WFFP method can tackle ratio optimization problems associated with fuzzy information, in which fuzzy possibilistic programming is integrated into a linear fractional programming framework. The method is applied to a case study of the Three (Yangtze-Yellow-Lantsang) Rivers Headwaters Region of China. The results can provide the basis for water and agricultural policies formulation and land-water-food nexus management in the study region.

Résumé :

Over the past years, rapid growth due to urbanization and industrialization, the changes in Land over and land use patterns have resulted in permanent environmental pollution to the hydrological processes. The hydrological cycle in cities is seriously affected due to increasing impervious areas as a result of urban development which has enhanced the risk of urban flooding. The increase in the impermeable area decreases infiltration, increases the runoff and reduces the time of concentration. Hence, for a given amount of rainfall, greater flooding is generated. Understanding the scope and limitation of sustainable stormwater management techniques detailed literature review is carried out. Site suitability is based on spatial analysis of data like geomorphology, slope, recharge condition, landuse and Landover map. Then analyzing local site conditions possible techniques that could be used to manage stormwater runoff are recommended and conclusions are drawn on the same.

Résumé :

Soil hydrology determines the water–soil–plant interactions in the Earth’s system, because porous medium acts as an interface within the atmosphere and lithosphere, regulates main processes such as runoff discharge, aquifer recharge, movement of water and solutes into the soil and, ultimately, the amount of water retained and available for plants growth. Soil hydrology can be strongly affected by land management. Therefore, investigations aimed at assessing the impact of land management changes on soil hydrology are necessary, especially with a view to optimize water resources. This Special Issue collects 12 original contributions addressing the state of the art of soil hydrology for sustainable land management. These contributions cover a wide range of topics including (i) effects of land-use change, (ii) water use efficiency, (iii) erosion risk, (iv) solute transport, and (v) new methods and devices for improved characterization of soil physical and hydraulic properties. They involve both field and laboratory experiments, as well as modelling studies. Also, different spatial scales, i.e., from the field- to regional-scales, as well as a wide range of geographic regions are also covered. The collection of these manuscripts presented in this Special Issue provides a relevant knowledge contribution for effective saving water resources and sustainable land management.

Résumé :

The agricultural community has a challenge of increasing food production by more than 70% to meet demand from the global population increase by the mid-21st century. Sustainable food production involves the sustained availability of resources, such as water and energy, to agriculture. The key challenges to sustainable food production are population increase, increasing demands for food, climate change, and climate variability, decreasing per capita land and water resources. To discuss more details on (a) the challenges for sustainable food production and (b) mitigation options available, a special issue on “Water Management for Sustainable Food Production” was assembled. The special issue focused on issues such as irrigation using brackish water, virtual water trade, allocation of water resources, consequences of excess precipitation on crop yields, strategies to increase water productivity, rainwater harvesting, irrigation water management, deficit irrigation, and fertilization, environmental and socio-economic impacts, and irrigation water quality. Articles covered several water-related issues across the U.S., Asia, Middle-East, Africa, and Pakistan for sustainable food production. The articles in the special issue highlight the substantial impacts on agricultural production, water availability, and water quality in the face of increasing demands for food and energy.

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 :

This paper provides a brief overview of how traditional concepts and approaches of land use planning have evolved into a more widely accepted vision of ‘land resources planning’ and its requirements for participatory processes, involvement of multi-sectoral stakeholders, and multi-thematic information at appropriate scales. Given its comprehensive ambitions, land resource planning (LRP) has a growing demand for a wide-ranging toolset, encompassing different tools in the biophysical, socio-economic, and governance (in a form of guidelines, methods, approaches and support tools). In order to collate knowledge, experiences and lessons from the LRP tools users, the Food and Agriculture Organization of the United Nations (FAO) - Land and Water Division held a consultation process through a survey among a range of stakeholders operating at different levels, sectors and regions. The survey evidenced limited awareness about the current availability of tools for land use planning. To remedy this situation, FAO developed the Land Resources Planning Toolbox (LRPT), a web-based inventory of existing tools. The Toolbox makes distinguishing between the tools in the socio-economic domain, those in the biophysical and the ones combining the two domains. The Toolbox explains the ability and restrictions of the LRP tools and their appropriateness to different regions, stakeholders and levels, and can be searched according to several criteria. It is concluded that, the Toolbox offers a useful mechanism for knowledge sharing and exchange of recent tools to enhance participatory LRP. It also has a great potential to support sustainable land management and landscape restoration. In this way it addresses, indirectly, conflicts and competition over resources.

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 :

Globally, the changes exerted on the land cover have shown greater impacts on the quality and quantity of water resources and thus affecting catchment’s hydrological response (i.e., runoff, evapotranspiration, infiltration, amongst others). South Africa is a water-scarce country faced with domestic water supply challenges. A systematic review was conducted on the overview impacts of land use/land cover changes on water resources. Despite the country’s best efforts in ensuring the protection and sustainable use of water resources, the review indicated that water quality has been compromised in most parts of the country thus affecting water availability. The increase in water demand with development presents the need for better integrated strategic approaches and a change in behaviour towards water resource and land management. Thus, the review suggested a few possible solutions that will promote sustainable development, while protecting and preserving the integrity of South African water resources.

Résumé :

AbstractAn agricultural facility aimed at sustainable production of crops in arid environments was built and tested in Hatzeva, Israel. The facility relies on solar-powered desalination with nanofiltration membranes to treat the local brackish water (EC=2.32 dS m−1) and produce high-quality irrigation water (EC=0.71 dS m−1). Red beet, a salt-tolerant crop, was grown with the concentrate stream (EC=4.73 dS m−1), eliminating the need for concentrate disposal and with potential net economic benefits. Agricultural experiments with variable irrigation water quality, application rate, and four staple crops (potato, maize, millet and sorghum) were conducted over two growing seasons between September 2010 and June 2011. The desalination plant operated at low pressure (4.3 bar) and energy consumption (1.37 kWh m−3) and with little maintenance over the entire study period. The results of the agricultural experiments consistently showed that irrigation with desalinated water promoted more efficient use of resources such as water and inorganic fertilizers. A reduction of 25% in the irrigation rate and use of fertilizers compared with best-practice guidelines was achieved with desalinated water, with no detectable detrimental effect on the marketable yield. On the contrary, a statistically significant yield increase was observed for sorghum (+10%). An increase in water productivity with desalinated water was observed for all four staple crops.

Résumé :

Abstract. The Tarim Basin in Xinjiang province in northwest China is characterized by a hyper arid climate. Climate change and a strong increase in agricultural land use are major challenges for sustainable water management. The largest competition for water resources exists between irrigated fields and natural riparian vegetation, which is dependent on seasonal flooding of the Tarim River. In addition to numerous water management measures implemented by the Chinese government, the Sino-German project SuMaRiO (Sustainable Management of River Oases along the Tarim River) provided a decision support system based on ecosystem services for the Chinese stakeholders. This tool will help to implement sustainable land and water management measures in the next 5-year plan.

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 :

Land cover and population is key in considering sustainable management of the environment. An assessment focusing on the two may aid planning for sustainable management of the ecosystems. This is particularly vital for the water tower ecosystems which are extremely vulnerable. This paper provides a scientific assessment on the extent of land cover change in Mau Water Tower Ecosystem from 1986 to 2015 using satellite images. It analyzes the implications of observed population dynamics and forecasts the extent of land cover change in this resource. The results indicate a sharp increase in the area covered by grassland with a drastic decline in forest cover. Cropland showed marked fluctuations during the entire period. The change in forest cover had a very strong significant negative relationship with the rapid population increase. Forecast on land cover change, based on a “Business as Usual” (BAU) scenario, indicated further decline in forest cover and an increase in the area covered by grassland. The results of the study suggest that land cover change and population growth within the water towers are closely interlinked and cause significant effects on these ecosystems. These findings lay the foundation for a review of conservation and agricultural policies in order to enhance sustainable management of Mau Water Tower.

Résumé :

Purpose – Temporary and permanent decline in the productive capacity of the land due to natural and human-induced activities such as soil erosion, changing cropping practices and less use of organic matter (OM) has been the greatest challenge faced by mankind in recent years, particularly in the hills and mountains of Nepal. Hence, the purpose of this paper is to examine the effectiveness of sustainable soil management practices to mitigate desertification process in the hills of Nepal. Design/methodology/approach – Promotion of sustainable soil management (SSM) practices through a decentralised agriculture extension approach by involving all the stakeholders in a participatory way. Findings – SSM practices mainly: OM management, fodder and forage promotion, increased biomass production systems, integrated plant nutrition systems, and bioengineering for soil and water conservation are identified as the most appropriate and relevant technologies in mitigating the desertification process without deteriorating land quality, particularly conserving the top-soils effectively and efficiently in the hills and mountains of the country. Research limitations/implications – This research is focus on the overall effect of SSM practices due to time and budget constraints. There is scope for doing research on the different aspects of SSM practices and the extent of their effect on different soil parameters (chemical, biological and physical). Practical implications – SSM interventions clearly indicated that there is significant impact in increasing soil fertility, conserving fertile top-soils and mitigating physical, chemical and biologic desertification processes. These are possible through maintaining and improving the soil organic matter, which is the most important indicator for soil health. SSM practices have resulted in an increase of up to 30 per cent in crop yield compared to yields without SSM practices. This might be due to the improvement in SOC which improves soil texture, increases nutrient supply from organic source and conserves water quality, thus, improving soil quality. Social implications – This has created awareness among farmers. Hence, farmers are mitigating pH through increased use of organic manures, where there is less availability of agriculture lime and they are far from road access. Originality/value – SSM practices significantly contributes to combat soil desertification in the hills of Nepal.

Résumé :

Tianjin, due to its severe shortage and inefficient use of water resource, is now facing many problems such as land substance, pollutions of wastewater irrigation etc., which will restrict its sustainable development of social economy. As a newly, useful, and potential unconventional water resource, reclaimed water can be used broadly to improve the unsatisfied situation of water utilization in Tianjin. In this paper, based on an analysis of the status of present reclaimed water use project and associated plans of future reclaimed water utilization, the authors gave a detailed discuss on the existed problem of reclaimed water use, and then put forward some relative suggestions and recommendations about the sustainable management of reclaimed water utilization in Tianjin, such as management mechanism, reclaimed water price and economic stimulating mechanism, constructions of infrastructure, supporting of science and technology, laws and policies, and supervision system and public participation.

Résumé :

<p>Systematic humanitarian demining carried out with care is an essential prerequisite for sustainable land management in post conflict settings. Degradation of land and pollution of water, soil and vegetation, as well as poisonous gas emissions that may even contribute to climate change, can be reduced significantly by humanitarian demining practices. Such practices simultaneously conserve natural resources and increase yields which results to sustainable land management. Mine Risk Education which is a major component of humanitarian demining, will have a lasting impact on people’s knowledge, attitudes and practices related to landmines making a positive contribution towards sustainable land management. This paper utilizes research publications from refereed journals and mine action authorities as well as ground information using the systematic literature review (SLR) method. The study investigates relations between humanitarian demining and sustainable land management in post conflict settings with a classic example from North East Sri Lanka. The practical implications for demining operators are that they can implement the strategies to improve the prevailing sustainable land management conditions of the communities in Sri Lanka and elsewhere.</p>

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 :

<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 :

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 :

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 :

The UN Sustainable Development Goals (SDGs) identify the need to restore degraded soils in order to improve productivity and the provision of ecosystem services. The aim is to support food production, store and supply clean water, conserve biodiversity, sequester carbon, and improve soil resilience in a context of climate change. Within this framework, in order to achieve the SDGs and to correct land management in the long-term, soil management is considered mandatory. The reduction of land degradation should be based on various sustainable soil management practices that improve and maintain soil organic matter levels, increase water infiltration, and improve soil water management. This technical review - a policy paper - summarizes the sustainable and territorial impact of soil degradation, including soil water erosion, from the global level to the European and National levels. Furthermore, with the aim of sharing ongoing soil and water management actions, instruments, and initiatives, we provide information on soil and water conservation activities and prospects in Italy.

Résumé :

Abstract In the open-pit mining system that is being carried out by a company in the mining sector with gold and silver commodities, PT Citra Palu Minerals, land clearing can cause soil erosion which can lead to soil sedimentation, increased turbidity of water that will be released into the environment and potential entry soil eroded into the tailings pond at the Dry Tailing Management Facility (DTMF). Therefore, further action is needed to control erosion and sedimentation as well as water management so that the water to be released into the environment is following environmental quality standards that have been set by the government. Before determining and controlling erosion, it is necessary to know the rate of erosion that occurs at the research location, in this study the USLE (Universal Soil Loss Equation) method was used to predict the rate of erosion with the results obtained, namely 17.07 tonnes/ha on the North DTMF slopes and 21.04 tonnes/ha for DTMF South slopes. To reduce the rate of erosion, it is necessary to control erosion by revegetation of the land, create a water drainage system to the sedimentation pond and treat the collected water using biophytoremediation of land with the use of chemicals to accelerate the deposition process, constructed swamp forest to the latest sustainable technology recommended by the Indonesian Academy of Sciences (LIPI).

Résumé :

Land degradation and desertification (LDD) and climate change are having increased effects in the Near East and North Africa (NENA) impacting the livelihoods of about 410 million people. Agriculture is a vital sector, contributing on average 14% to the Gross Domestic Product (GDP) (excluding oil producing countries) and providing jobs and incomes for 38% of the region’s economically active population. Nevertheless, most NENA countries import at least 50% of the calories they consume. Furthermore, it is estimated that the total area that is desertified or is vulnerable to desertification cover 9.84 million km2 or about 86.7% of the total NENA region. Soil erosion by water, wind, and sand and dust storms (SDS) cause losses of about USD 13 billion of GDP each year. To confront these hardships, the region must endorse proper land use planning, prioritization of target areas for restoration and adoption of sustainable land and water management (SLWM) to reverse the situation. This paper analyses the inter-linkages between LDD, resource base management and food security under different scenarios and offers mitigation and remediation options. These include knowledge management and sharing; establishment of a regional platform to facilitate dialogue; public and private investment opportunities; provision of tools to scale-out sustainable land and water management options; and creation of a conducive enabling environment supported by policies and strategies. The paper provides policy and decision-makers with priority actions and options to enhance productivity, and combat land degradation to improve food security in the region.

Résumé :

One of the tasks of sustainable water-quality and resources management must be to resolve conflicts between its demands and those of agriculture and ecology. In most industrial countries, there are conflicts between the different requirements of water supply, i.e. water quality, and those of agriculture and the conservation of wetlands, i.e. water quantity. Solving these conflicts means a reorganisation of land use. A non-governmental committee has initiated a voluntary compromise program for the water-protection zone of the Donauried. On the basis of criteria assessing the significance of areas of land, a plan for the reorganisation of land use has been developed. Moreover, an action plan has been prepared; it includes steps for reducing nitrate, a program for reducing land-use intensity, a concept for re-wetting bog areas and an investigation into measures for optimising local water resources using a numerical groundwater model. This was accompanied by an economic evaluation of the measures.

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 :

The significance of the security of electrical energy, water, and food resources in the future, which are inextricably connected, has led to increasing attention to this important issue in studies. This is an issue inattention to which can have irreparable consequences in the future. One of the sectors where electrical energy, water, and food are very closely associated is agriculture. Undoubtedly, the ability to properly manage electrical energy, hydropower, and food resources that have many uncertainties brings about the development of agriculture on the one hand and the optimal allocation of electrical energy, water, and land resources on the other. Thus, while reaching the highest economic profit, the greenhouse gas emissions reach the minimum possible value too. In this study, via robust optimization and by precisely considering the existing uncertainties, a model was developed for the optimal allocation of electrical energy, water, and land resources for a region in the north of China. In addition to acknowledging the close relationship between electrical energy, water, and food sources, the results show the method’s effectiveness for sustainable management in agriculture.

Résumé :

Location-specific forms of agroforestry management can reduce problems in the forest–water–people nexus, by balancing upstream and downstream interests, but social and ecological finetuning is needed. New ways of achieving shared understanding of the underlying ecological and social-ecological relations is needed to adapt and contextualize generic solutions. Addressing these challenges between thirteen cases of tropical agroforestry scenario development across three continents requires exploration of generic aspects of issues, knowledge and participative approaches. Participative projects with local stakeholders increasingly use ‘serious gaming’. Although helpful, serious games so far (1) appear to be ad hoc, case dependent, with poorly defined extrapolation domains, (2) require heavy research investment, (3) have untested cultural limitations and (4) lack clarity on where and how they can be used in policy making. We classify the main forest–water–people nexus issues and the types of land-use solutions that shape local discourses and that are to be brought to life in the games. Four ‘prototype’ games will be further used to test hypotheses about the four problems identified constraining game use. The resulting generic forest–water–people games will be the outcome of the project “Scenario evaluation for sustainable agroforestry management through forest-water-people games” (SESAM), for which this article provides a preview.

Résumé :

Purpose – The purpose of this paper was to enhance and complement teaching about resource system feedbacks and environmental modelling. Students were given an interactive exercise based on a research model (ForeseerTM), developed by an inter-disciplinary research team, that explores the interconnectivity of water, energy and land resources. Two groups of students were involved, one of undergraduates and the other of graduates. Design/methodology/approach – The Foreseer model represents physical flows of the three resources (water, energy and land) using an interactive visual interface. The exercise was set up by giving students short instructions about how to use the tool to create four scenarios, and an online questionnaire was used to capture their understanding and their ability to extract information from the model. Findings – The exercise proved to be a helpful way to connect research and teaching in higher education, to the benefit of both. For students, it was an interactive and engaging way to learn about these complex sustainability issues. At the same time, it provided tangible feedback to researchers working on the model about the clarity of its user interface and its pedagogic value. Originality/value – This exercise represents a novel use of a resource model as a teaching tool in the study of the water, energy and land nexus, and is relevant to sustainability educators as an example of a model-centred learning approach on this topic.

Résumé :

Due to its complex and often difficult nature, suboptimal lands are either under-utilized and left as abandoned space or over-utilized and generate environment problems. In reality, it can be the answer to the future challenge in 2050, where the growing population needs more food to survive. It results in intense competition in land conversion to agricultural and nonagricultural purposes. This paper introduces Water Management Trinity as an integrated water management system applied to exert the highest benefits from sustainable suboptimal lands cultivation in Pulau Burung District for at least the last 50 years. The three main components: the canal, the dike, also the dam and water gate principally regulate the freshwater from the precipitation events. With a cumulative length of more than 4000 km, the canals hold a volume of at least 45 million m3 of freshwater. Combined with the soil technology, the current agriculture practice is proven to reduce environmental damage by maintaining the land humidity so that the fire and flooding risk are both diminished while the land subsidence rate is kept under 0-4 cm/year in the last ten years. Simultaneously, the local socioeconomic sector flourishes as the system secures the water requirement for plant commodities production and supports freshwater supply.

Résumé :

Management of land and water resources has emerged as a vital issue in promoting biodiversity and ecological security programmes. The basic message of ecological security is not of containing development to save ecology but of managing ecology to promote development. What is good for development is equally good for ecology. Developmentalists point out that development not only provides for all-round expansion of the economy but also brings capacity for improving the quality of ecology. Therefore the basic issue is that the wheel of development must move on but it should advance within the supportive capacity of the ecosystem. Any desired development should have the ingredients of efficiency, equity and democracy. When this is done the people tend to take ecology-friendly decisions. The validity of the above ideas is tested through a case study on Palar river basin. Management of Palar river basin against water pollution requires effective monitoring and implementation of protective measures not only for the management of water care but also for the land care as well. In doing so, this study analyses the grave problems posed by tannery effluents and suggest measures for achieving sustainable development, environment and livelihood security.

Résumé :

The circumstance of suboptimal land, due to its complex and often difficult nature, is either under-utilized and becomes abandoned space or over-utilized and generates environmental problems. In fact, suboptimal land, including peatlands, can be an alternative amid the decreasing area of arable land per capita for agriculture. This study aims to assess the contribution of sustainable agriculture for coconut commodities in the peatlands area, Pulau Burung District, Indragiri Hilir Regency, Riau Province. Data on environmental aspects were obtained from secondary data provided by the local company. Data on socio-economic aspects were obtained using focus group discussions (FGD) in five villages through semi-structured interview to 29 residents from various backgrounds. As a result, agricultural practices in this area can be deemed as sustainable based on water management indicators. The environmental impact is very minimal, biodiversity is preserved, and the subsidence rate is very low at 1.7 cm per year. In terms of socio-economic aspect, it can be concluded that the community perceives the environmental and social aspects are well maintained. Referring to the results of the FGD on agricultural practices, land fire control, food access, waste management, and water access are aspects that are considered adequate for the community. In contrast, land governance scored the lowest due to the difficulties in obtaining land certificates. Keywords: peatland, suboptimal land, sustainable agriculture, water management

Résumé :

Agricultural production can only be sustained on a long term basis if the land, water and forests on which it is based are not degraded further. Improvements in water resources management are essential to raise agricultural productivity and reduce land degradation and water pollution. Salinization, alkalization and water logging should be addressed by a more careful approach to drainage and the regulation of water quantities through efficient use of irrigation water, which require that water be applied to growing crops at appropriate times and in adequate. The integrated management of water resources could only be possible through adoption of efficient and optimum use of irrigation water, which could only be ensured by judicious and economic use of irrigation potential whatsoever created to increase crop production. The integrated water resources management also includes the concept of rainwater management that has got an immense important on the way to develop the rainfed farming system. It has got relevancy particularly in installing small-scale irrigation system based on farmers’ participatory approach for sustainable crop production for maintaining sustainable growth and development of agriculture. Modern irrigation techniques like sprinkler and drip should be promoted when water is scarce and the topographic and soil conditions do not permit efficient irrigation by conventional methods. Promotions of such water saving devices should be an objective of the national water policy. Water resource management is a integrated and multidisciplinary activity, managing irrigation water that needs agronomy and crop husbandry, efficient methods and system of irrigation needs soils scientists and engineers. More than 98% of the irrigated lands are under the coverage of surface irrigation where more than 50% of water as considered as wastages wherein effective minimization of wastage of water used for irrigation and application of right quantity of water at right time will be the key to successful management of this crucial resource. So question of judicious management of water is pertinent while prioritizing researchable issues became of national importance.
