    État des forêts méditerranéennes 2018 2020

    The Mediterranean region has more than 25 million hectares of Mediterranean forests and about 50 million hectares of other Mediterranean wooded lands. They make crucial contributions to rural development, poverty alleviation, food security, as well as, the agricultural, water, tourism, and energy sectors. Changes in climate, societies, and lifestyles to create appropriate financial incentives and tools. in the Mediterranean region could have serious negative consequences for forests, with the potential to lead to the loss or diminution of those contributions and to a wide range of economic, social and environmental problems. In the future, Mediterranean forests will support agriculture and human wellbeing. It is therefore crucial to improve policies, practices, and to promote sustainable management to provide social and economic benefits as well as to increase the resilience of ecosystems and societies. This new edition of the State of Mediterranean Forests aims to demonstrate the importance of Mediterranean forests to implementing solutions to tackle global issues such as climate change and population increase. Part 1: The Mediterranean landscape: importance and threats. Despite the important natural capital provided by Mediterranean forests, they are under threats from climate change and population increase and other subsidiary drivers of forest degradation. Part 2: Mediterranean forest-based solutions. Forests and landscape restoration, adaptation of forests and adaptation using forests, climate change mitigation, and conserving biodiversity are additional and complementary approaches to address the drivers of forest degradation to the benefit of populations and the environment. Part 3: Creating an enabling environment to scale up solutions. To scale up and replicate forest-based solutions, there is a need to change the way we see the role of forests in the economy, to put in place relevant policies, more widespread participatory approaches, to recognize the economic value of the goods and services provided by forests and, ultimately, to create appropriate financial incentives and tools.

    La FAO et les objectifs de développement durable
    Autonomiser les communautés locales pour réaliser le Programme 2030
    2022
    Les objectifs de développement durable (ODD) nous concernent chacun individuellement. Mais du fait de la résurgence de conflits, du dérèglement climatique et des crises sociales et sanitaires, nous risquons de les perdre de vue. Or ils sont notre meilleure arme pour améliorer l’avenir des populations et de la planète. La présente publication montre comment la FAO et ses partenaires poursuivent leurs efforts en vue de réaliser les ODD, projet après projet, secteur après secteur, et pays après pays.

    Sols et biodiversité
    Les sols abritent un quart de la biodiversité de la planète
    2015
    La diversité biologique ou biodiversité est décrite comme «la variabilité des organismes vivants de toutes origines – terrestre, aquatique ou marine». Cela comprend la diversité au sein des espèces (diversité génétique), entre les espèces (diversité des organismes) et des écosystèmes (diversité écologique). Les sols constituent l’un des écosystèmes les plus complexes de la nature, et l’un des habitats les plus diversifiés sur terre: ils abritent des milliers d’organismes différents, qui interagi ssent et contribuent aux cycles globaux qui rendent possible la vie. Nulle part dans la nature on ne retrouve une densité d’espèces aussi importante que dans les communautés du sol. Toutefois, cette biodiversité reste peu connue du fait qu’elle est souterraine et en grande partie invisible à l’oeil nu.

    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.

    What will be needed to realize the vision of a world free from hunger and malnutrition? After shedding light on the nature of the challenges that agriculture and food systems are facing now and throughout the 21st century, the study provides insights into what is at stake and what needs to be done. “Business as usual” is not an option. Major transformations in agricultural systems, rural economies, and natural resources management are necessary. The present study was undertaken for the quadrennial review of FAO’s strategic framework and for the preparation of the Organization Medium-Term plan 2018-2021.
