Book (series)General interest bookNature-Based Solutions for Agricultural Water Management and Food Security 2018
Also available in:
No results found.Accessibility to clean and sufficient water resources for agriculture is key in feeding the steadily increasing world population in a sustainable manner. Nature-Based Solutions (NBS) offer a promising contribution to enhance availability and quality of water for productive purposes and human consumption, while simultaneously striving to preserve the integrity and intrinsic value of the ecosystems. Implementing successful NBS for water management, however, is not an easy task since many ecosystems are already severely degraded, and exploited beyond their regenerative capacity. Furthermore, ecosystems are large and complex and the many stakeholders involved might have conflicting interests. Hence, implementation of NBS requires a structured and comprehensive approach that starts with the valuation of the services provided by the ecosystem. The whole set of use and non-use values, in monetary terms, provides a factual basis to guide the implementation of NBS, which ideally is done according to transdisciplinary principles, i.e. complemented with scientific and case-specific knowledge of the eco-system in an adaptive decision-making process that involves the relevant stakeholders. This discussion paper evaluated twenty-one NBS case studies using a non-representative sample, to learn from successful and failed experiences and to identify possible causalities among factors that characterize the implementation of NBS. The case studies give a minor role to valuation of ecosystem services, an area for which the literature is still developing guidance. Less successful water management projects tend to suffer from inadequate factual and scientific basis and uncoordinated or insufficient stakeholder involvement and lack of long term planning. Successful case studies point to satisfactory understanding of the functioning of ecosystems and importance of multi-stakeholder platforms, well-identified funding schemes, realistic monitoring and evaluation systems and endurance of its promoters. -
Brochure, flyer, fact-sheetBrochureObservations and key messages on Nature-Based Solutions for agricultural water management and food security 2018

No results found.Food and agricultural systems are under a set of pressures to feed an increasingly hungry population and to cope with an intensifying competition over natural, human and financial resources, all subject to impacts of climate change. The natural resource base is already degraded to significant levels, and ‘’business as usual’’ is no longer an option. FAO has been emphasizing the need to accelerate a global transition to sustainable food and agriculture systems, advocating an integrated approach to ensure sustainability in production and subsequent value chains processes, taking into account the sustainable management of natural resources, and water resources in particular. This document focuses on the management of water for agricultural use, which holds the largest share of total water demand for many countries as illustrated by Figure 1. Moreover, for many countries, the prospects of improving water availability under changing climatic conditions remain a challenge, as both droughts and flood hazards are expected to increase. Conventional interventions founded on ‘hard’ water engineering and infrastructural development provided valuable lessons but often showed that they compromise the very ecosystem services that are required for stable water flows. Hence, calls for a paradigm shift in water management are justified and should be a priority on the political agendas. -

Webinar 5: Nature-based solutions for agricultural water management and food security
2018Also available in:
No results found.The 2018 edition of the World Water Development Report seeks to inform policy and decision makers, inside and outside the water community, about the potential of nature-based solutions (NBS) to address contemporary water resource management challenges across all sectors, and particularly regarding water for agriculture, sustainable cities, disaster risk reduction and water quality. Water resource management remains heavily dominated by traditional, human-built (i.e. ‘grey’) infrastructure and the enormous potential for NBS remains under-utilized. NBS include green infrastructure that can substitute, augment or work in parallel with grey infrastructure in a cost-effective manner. The goal is to find the most appropriate blend of green and grey investments to maximize benefits and system efficiency while minimizing costs and trade-offs.

Book (series)FlagshipThe State of Food Security and Nutrition in the World 2021
Transforming food systems for food security, improved nutrition and affordable healthy diets for all
2021In recent years, several major drivers have put the world off track to ending world hunger and malnutrition in all its forms by 2030. The challenges have grown with the COVID-19 pandemic and related containment measures. This report presents the first global assessment of food insecurity and malnutrition for 2020 and offers some indication of what hunger might look like by 2030 in a scenario further complicated by the enduring effects of the COVID-19 pandemic. It also includes new estimates of the cost and affordability of healthy diets, which provide an important link between the food security and nutrition indicators and the analysis of their trends. Altogether, the report highlights the need for a deeper reflection on how to better address the global food security and nutrition situation.To understand how hunger and malnutrition have reached these critical levels, this report draws on the analyses of the past four editions, which have produced a vast, evidence-based body of knowledge of the major drivers behind the recent changes in food security and nutrition. These drivers, which are increasing in frequency and intensity, include conflicts, climate variability and extremes, and economic slowdowns and downturns – all exacerbated by the underlying causes of poverty and very high and persistent levels of inequality. In addition, millions of people around the world suffer from food insecurity and different forms of malnutrition because they cannot afford the cost of healthy diets. From a synthesized understanding of this knowledge, updates and additional analyses are generated to create a holistic view of the combined effects of these drivers, both on each other and on food systems, and how they negatively affect food security and nutrition around the world.In turn, the evidence informs an in-depth look at how to move from silo solutions to integrated food systems solutions. In this regard, the report proposes transformative pathways that specifically address the challenges posed by the major drivers, also highlighting the types of policy and investment portfolios required to transform food systems for food security, improved nutrition, and affordable healthy diets for all. The report observes that, while the pandemic has caused major setbacks, there is much to be learned from the vulnerabilities and inequalities it has laid bare. If taken to heart, these new insights and wisdom can help get the world back on track towards the goal of ending hunger, food insecurity, and malnutrition in all its forms. -

Also available in:
No results found.These country reports are prepared as a contribution to the FAO publication, The State of the World’s Biodiversity for Food and Agriculture. The preparation of Country Reports provided an overview of existing information gaps and helped to establish a baseline information on biodiversity for food and agriculture. They also provided information on the role of biodiversity for food and agriculture in the provision of multiple ecosystem services. These country reports helped to address the following questions: • What is the state of the conservation and use of biodiversity for food security and nutrition, ecosystem services and sustainability? • What trends can be identified in the conservation and use of biodiversity for food and agriculture and in the effects of major drivers of change? • How can conservation and use of biodiversity for food and agriculture be improved and the contributions of biodiversity to food security and nutrition, ecosystem services, sustainability and the improvement of livelihoods of farmers, pastoralists, forest dwellers and fisher folk be enhanced? -
