    2020年粮食及农业状况
    应对农业中的水资源挑战
    2020
    愈演愈烈的缺水问题对粮食安全和营养构成威胁。因此,迫切需要采取行动,在农业生产中更可持续、更公平地利用水资源。灌溉农业依然是淡水资源的最大用户,但随着对淡水资源的需求和竞争不断升级,淡水资源短缺问题正日益加重。同时,雨养农业正面临气候变化带来的降雨波动幅度不断加大的问题。这些趋势将加剧水资源使用者之间的矛盾纠纷和水资源获取方面的不平等,尤其对小农、农村贫困人口及其他弱势群体而言。《2020年粮食及农业状况》就灌溉农业中普遍存在的水资源短缺问题、雨养农业中普遍存在的水资源不足问题以及受影响人口数量提供了新的估计数字。报告发现,各国之间存在巨大差异,各国内部同样也存在巨大的空间差异。这一实证可为各方提供参考依据,去探讨各国应如何根据问题的性质和大小以及包括农业生产系统类型、国家发展水平和政治结构在内的其他因素制定合理的政策和干预措施。在此基础上,本报告就各国应如何对各项政策和干预措施进行优先排序提供了指导意见,以应对农业中的缺水问题,确保人们能高效、可持续、公平地获取水资源。

    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.

    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.

    Emissions due to agriculture
    Global, regional and country trends 2000–2018
    2021
    Also available in:
    No results found.

    The FAOSTAT emissions database is composed of several data domains covering the categories of the IPCC Agriculture, Forestry and Other Land Use (AFOLU) sector of the national GHG inventory. Energy use in agriculture is additionally included as relevant to emissions from agriculture as an economic production sector under the ISIC A statistical classification, though recognizing that, in terms of IPCC, they are instead part of the Energy sector of the national GHG inventory. FAO emissions estimates are available over the period 1961–2018 for agriculture production processes from crop and livestock activities. Land use emissions and removals are generally available only for the period 1990–2019. This analytical brief focuses on overall trends over the period 2000–2018.
