    With worldwide concerns about water scarcity, agriculture is under pressure to improve water management and explore available options to match supply and demand. Desalination is a technical option to increase the availability of freshwater both in coastal areas with limited resources and in areas where brackish waters are available. Water desalination is the main source of potable water in some countries and in many islands around the world and it is also being used in certain coun tries to irrigate high-value crops. However, it has proven much less economic for agricultural application than the reuse of treated wastewater, even where the capital costs of the desalination plants are subsidized.

    The integration of desalination into agricultural practices presents a transformative opportunity to address water scarcity in a rapidly changing climate. This guidance document has highlighted the technological advances, agronomic opportunities, economic challenges, environmental impacts and social considerations associated with doing so.Technologically, desalination has evolved significantly, offering viable solutions for both seawater and brackish water, with reverse osmosis leading the way. However, the high costs and energy requirements of desalination remain significant challenges, particularly for widespread agricultural use. Innovations in energy efficiency, brine management, and the potential for resource recovery from brine are promising developments that could lower costs and environmental impacts in the future.Agronomically, desalinated water can support high-value crops, and it has the potential to support food security in regions facing severe water scarcity. However, the unique chemical composition of desalinated water, including low nutrient content and the potential for phytotoxicity, necessitates careful management to avoid adverse effects on soil health and crop productivity. Blending desalinated water with water from other sources and adjusting fertilization practices can mitigate some of these concerns.Economically, the viability of desalination for agriculture depends on the value of the crops being irrigated, the proximity of desalination plants to agricultural lands, and the availability of financing mechanisms. The high cost of desalinated water requires targeted subsidies, public–private partnerships, and innovative financing models to make it accessible and sustainable for farmers, particularly in developing regions. Further research is needed to analyse the costs and benefits of desalination for “strategic” crops in water-scarce areas – such as cereals and animal fodder – which are intended to contribute to food security.Environmental sustainability is a critical consideration, with desalination’s energy intensity and brine disposal posing significant risks. The shift towards renewable energy sources and the development of brine valorization strategies are essential steps towards reducing the environmental footprint of desalination. Moreover, the potential for desalination to contribute to aquifer recharge and prevent overextraction of freshwater resources offers additional environmental benefits.

    The State of Food Security and Nutrition in the World 2021
    Transforming food systems for food security, improved nutrition and affordable healthy diets for all
    2021
    In 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.

    The Protocol of 8-9 July 1946 relative to the dissolution of the International Institute of Agriculture, transferred the functions and assets of the said Institute to FAO. Of these assets, the Library is unquestionably the most outstanding and is a lasting record of the Institute's work and its achievement in the field of agriculture. This catalogue will undoubtedly contribute towards a better knowledge of this international Library. This volume in its present form, represents the systematic card-index, by subject of the Brussels Decimal Classification, in French and English, and it's supplemented by the general alphabetical index of authors.

    This is Part 2 of 4 - Books - section Pure Sciences, Applied Sciences, Hygiene, Fine Arts, Literature, History, Geography and Biography.

    FAO Strategy on Climate Change 2022–2031 2022
    The FAO Strategy on Climate Change 2022–2031 was endorsed by FAO Council in June 2022. This new strategy replaces the previous strategy from 2017 to better FAO's climate action with the Strategic Framework 2022-2031, and other FAO strategies that have been developed since then. The Strategy was elaborated following an inclusive process of consultation with FAO Members, FAO staff from headquarters and decentralized offices, as well as external partners. It articulates FAO's vision for agrifood systems by 2050, around three main pillars of action: at global and regional level, at country level, and at local level. The Strategy also encourages key guiding principles for action, such as science and innovation, inclusiveness, partnerships, and access to finance.
