    Documento sobre el proceso de FRA 2015 2017

    Desde su fundación, la FAO ha reunido, analizado, interpretado y divulgado periódicamente información sobre la situación y las tendencias de los recursos forestales mundiales por medio de la Evaluación de los recursos forestales mundiales (FRA). El alcance de las evaluaciones y los métodos que se emplean en ellas han evolucionado con el tiempo para responder a los cambios producidos en las necesidades de información, aumentar el nivel de participación de los países, así como modernizar y armoniz ar las definiciones y la presentación de informes en colaboración con otras organizaciones y procesos internacionales de presentación de informes. El FRA 2015 es la Evaluación de los recursos forestales mundiales de la FAO más reciente, en la que se siguió aplicando y se mejoró este enfoque participativo integral, más amplio. En el presente documento se ofrece un resumen de las distintas fases por las que se pasó para completar el FRA 2015, desde el proceso de diseño a la aplicación y la difusió n de los resultados.

    Los bosques y el agua: Estudio temático elaborado en el ámbito de la Evaluación de los recursos forestales mundiales 2005

    En muchas regiones del mundo, la disponibilidad y calidad del agua potable cada vez está más amenazada por su explotación excesiva, el mal uso y la contaminación. En este contexto, la relación entre los bosques y el agua debe recibir una gran prioridad. Las cuencas de captación forestales suministran una gran parte del agua destinada a satisfacer las necesidades domésticas, agrícolas, industriales y ecológicas, tanto en las zonas de río arriba como en las de río abajo. Un desafío importante que afrontan los responsables de la ordenación de las tierras, los bosques y el agua es elevar al máximo los beneficios que ofrecen los bosques sin menoscabo de los recursos hídricos y la función del ecosistema. Es urgente comprender mejor la interacción entre los bosques y los árboles con el agua e incorporar este conocimiento en las políticas. Este estudio, iniciado en el ámbito de la Evaluación de los recursos forestales mundiales 2005, destaca la necesidad de una ordenación integral de los compl ejos ecosistemas de las cuencas hidrográficas que tenga en cuenta la interacción entre el agua, los bosques y otros usos de la tierra, así como los factores socioeconómicos. Explica la función de los bosques en el ciclo hidrológico, con atención particular a las situaciones críticas de alerta forestal, como los terrenos montañosos o empinados, las zonas fluviales y costeras y los ecosistemas palustres, así como el caso especial de las islas pequeñas montañosas. Trata la protección del suministro municipal de agua y los nuevos sistemas de pago por servicios de cuenca. Esta publicación de los conocimientos más avanzados será de interés para una amplia gama de expertos técnicos, científicos y responsables de tomar las decisiones.

    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.

    Restoring the Earth - The next decade
    Unasylva No. 252 - Vol. 71 2020/1
    2020
    This Unasylva issue aims at showcasing forest and landscape restoration (FLR) opportunities and recent developments that have the power to upscale restoration, in order to achieving the Bonn Challenge pledge and other national and international commitments (Sustainable Development Goals (SDGs), the Convention for Biological Diversity (CBD) Post-2020 Agenda, the United Nations Convention to Combat Desertification (UNCCD) Land Degradation Neutrality, Paris Agreement under the United Nations Framework Convention on Climate Change (UNFCCC)) and addressing the needs of the UN Decade 2021-2030 on Ecosystem Restoration. The content adresses thematics of relevance to various audiences: i) flagship restoration initiatives that differ from the so-called “business-as-usual” as they channel more funds, better empower local stakeholders and provide enhanced technical assistance through partners’ coalitions; ii) technical advances that can spread FLR and have a huge potential to be mainstreamed for different reasons (low cost, adaptability, relevance to many ecosystems and contexts, ease of implementation…); iii) the enabling factors for restoration, i.e. coordination, policy environment, resources, knowledge and capacities, as these are the enabling conditions for action to take place on the ground.

    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.
