Ecosystem restoration and inland food fisheries in developing countries by Food and Agriculture Organization of the United Nations Pdf
The review presents the strong business case for inland food fisheries in developing countries to be either a co-benefit, or very often the main benefit, of ecosystem restoration. In view of the current state of inland water aquatic habitats the potential for restoration is high. Realizing this potential requires concerted action to overcome current challenges, foremost of which is the invisibility of inland fisheries in many policy arenas as well as technical and scientific fora. The drivers of ecosystem degradation, ecosystem services valuation frameworks and the main technical tools for implementing interventions are presented. Experiences in developed countries dominate the literature but are not necessarily applicable to developing country inland food fisheries. Local communities that have high dependency on inland fisheries and live in close association with inland water fisheries habitats not only provide much higher fisheries values but a management asset that is unavailable in developed countries and the mainstay of many successful restoration programmes. Ten case studies, representing effective restoration of food fisheries from local to basin scale are used to illustrate what can be achieved. The prospects of inland fisheries benefiting from, or contributing to, the UN Decade on Ecosystem Restoration (2021–2030) are good but upscaling the existing progress will require increased and sustained efforts to mainstream the values of inland fisheries including their co-benefits for biodiversity conservation.

Global drylands, covering over 40% of Earth’s land surface, are important among worldwide ecoregions and support large human and livestock populations. However, these ecologically sensitive ecoregions are undergoing a rapid transformation resulting from climate change, socioeconomic and political factors, increases in population, and ever-growing demands for goods and services. Managing Soil Drought addresses basic processes and provides specific case studies throughout covering the protection, restoration, and sustainable management goals of global drylands under changing and harsh climatic conditions, including fragile and vulnerable ecosystems. The book is written by numerous researchers, academicians, practitioners, advocates, land managers, and policymakers involved in bringing about transformation in these regions important to human and nature. It includes information on basic strategies of sustainable management of global drylands aimed at improving water use efficiency through choosing appropriate species, developing new varieties, using organic and inorganic amendments, and scaling up innovative farming systems. This volume in the Advances in Soil Sciences series is an essential read for development organizations and policymakers involved in improving crop productivity and sustainability in drought-prone regions; students, researchers, and academicians interested in sustainable management of water resources; and those involved in emerging concepts of regenerative agriculture, agroecology, and conservation agriculture.
The State of the World’s Land and Water Resources for Food and Agriculture 2021 – Systems at breaking point by Food and Agriculture Organization of the United Nations Pdf
Satisfying the changing food habits and increased demand for food intensifies pressure on the world’s water, land and soil resources. However, agriculture bears great promise to alleviate these pressures and provide multiple opportunities to contribute to global goals. Sustainable agricultural practices lead to water saving, soil conservation, sustainable land management, conservation of natural resources, ecosystem and climate change benefits. Accomplishing this requires accurate information and a major change in how we manage these resources. It also requires complementing efforts from outside the natural resources management domain to maximize synergies and manage trade-offs. The objective of SOLAW 2021 is to build awareness of the status of land and water resources, highlighting the risks, and informing on related opportunities and challenges, also underlining the essential contribution of appropriate policies, institutions and investments. Recent assessments, projections and scenarios from the international community show the continued and increasing depletion of land and water resources, loss of biodiversity, associated degradation and pollution, and scarcity in the primary natural resources. SOLAW 2021 highlights the major risks and trends related to land and water and presents means of resolving competition among users and generating multiple benefits for people and the environment. The DPSIR framework was followed in order to identify the Drivers, Pressures, Status, Impact and Responses. SOLAW 2021 provides an update of the knowledge base and presents a suite of responses and actions to inform decision-makers in the public, private, and civil sectors for a transformation from degradation and vulnerability toward sustainability and resilience.
Increasing the benefits and sustainability of irrigation through integration of fisheries by Food and Agriculture Organization of the United Nations ,WorldFish, International Water Management Institute Pdf
There is increasing recognition of the need to bring about changes across the full spectrum of agricultural practices to ensure that, in future, food production systems are more diverse, sustainable and resilient. In this context, the objectives of irrigation need to be much more ambitious, shifting away from simply maximizing crop yields to maximizing net benefits across a range of uses of irrigation water, including ecosystems and nature-based solutions. One important way to achieve this is by better integrating fisheries into the planning, design, construction, operation and management of irrigation systems. Irrigation – a major contributor to the Green Revolution – has significantly improved agricultural production worldwide, with consequent benefits for food security, livelihoods and poverty alleviation. Today, irrigated agriculture represents about 21 percent of cultivated land, but contributes approximately 40% of the total global crop production. Many governments continue to invest in irrigation as a cornerstone of food security and rural development. Investments in irrigation often represent a pragmatic form of adaptation to changing climatic conditions. This guide focuses on how to sustainably optimize and broaden the range of benefits from irrigation development - not only economic but also social and environmental benefits . It emphasizes the opportunities that fisheries could provide to increase food production and economic returns, enhance livelihoods and public health outcomes, and maintain key ecosystem services. The guide considers possible trade-offs between irrigation and fisheries, and provides recommendations on how these could be minimized.

Mais contrairement à la plupart des autres ressources naturelles, il s’est avéré extrêmement difficile de déterminer sa véritable «valeur». L'édition 2021 du rapport mondial sur la mise en valeur de l'eau des Nations Unies, intitulée «Valuing Water» évalue l'état actuel et les défis de la valorisation de l'eau dans différents secteurs et perspectives et identifie les moyens de promouvoir sa valorisation en tant qu'outil pour aider à améliorer sa gestion et parvenir à un développement durable à l’échelle mondiale.
Source-to-Sea Management by Josh Weinberg,Fang Qinhua,Sarantuyaa Zandaryaa,Greg Leslie,James E. Nickum Pdf
This book is the first of its kind on the emerging topic of source-to-sea management. It showcases different applications of the concept to improve the environmental health of freshwater, land and coastal and marine systems, drawing upon research performed across Europe, Africa and Asia. Improved management of land, freshwater, coasts and oceans is a key environmental challenge of our time. It is needed to prevent the millions of tons of plastic and other pollutants that enter the ocean from land-based sources each year. It is essential to reduce highly polluted, oxygen-depleted “dead zones” in our coastal and marine waters. Extensive diversions of the flows of rivers need to be avoided to ensure that little or no water reaches the sea. Source-to-sea (S2S) is an emerging concept to improve understanding of how to effectively manage freshwater, land, coastal and marine systems. The collected works in this book explore experiences with S2S management in diverse regions across Europe, Asia, Africa and Australia, addressing sedimentation, nutrient and pharmaceutical pollution in freshwater and marine aquatic environments, and marine debris on the coasts and in the seas. It provides key insights into a few areas that should be of interest to those who want to learn from the lessons from case studies of applied S2S interventions. This book will be of great value to scholars, students and researchers interested in global freshwater, coastal zone, ocean management, sustainable development and environmental governance. The chapters in this book were originally published as a special issue of the journal Water International.
The Omo-Turkana Basin by Jonathan Lautze,Matthew McCartney,Julie Gibson Pdf
This book provides a comprehensive examination of water resource management in the Omo-Turkana Basin, linking together biophysical, socioeconomic, policy, institutional and governance issues in a solutions-oriented manner. The Omo-Turkana Basin is one of the most important lake basins in Africa, and despite the likely transboundary impacts associated with the management of dams, it is the largest lake basin in Africa without a cooperative water agreement. This volume provides a foundation for integrated decision-making in the management of development in the Lake Turkana Basin. Chapters cover water-related conditions, hydropower, agriculture, ecosystems, resilience and transboundary governance. The final chapter proposes ways forward in light of the potential benefits that can be achieved through cooperation, and practical realities that cooperation is slow and may take time to achieve. This book will be of great interest to students and scholars of water and natural resource management, environmental policy, sustainable development and African studies. It will also be relevant to water management professionals.
