DocumentOther documentCómo aumentar la regeneración de árboles maderables en potreros? 2001
Also available in:
No results found.La producción ganadera es una de las formas de uso de la tierra más frecuentes en América Latina, especialmente la ganadería vacuna. En cada uno de los países existen desde pequeños productores, hasta explotaciones de gran escala con procesos integrados, los cuales en su mayoría están basados en pasturas naturales o establecidas, muchas veces incluyendo árboles dentro de estos sistemas. Sin embargo, hasta hace poco no eran valorados los beneficios de los árboles dentro de las pasturas. Hoy en d ía se han documentado muchas ventajas de los arboles en estos sistemas silvopastoriles como protección de los animales del calor o del frío a lo largo del día y de las estaciones, alimentación en épocas de escasez de forraje, producción de madera y leña, mejoras en las pasturas, reciclaje de nutrientes, etc. Manejar la regeneración natural de árboles maderables dentro de las pasturas es una alternativa para el mejoramiento de este tipo de sistemas. -

No results found.Los árboles dispersos son una característica común del paisaje agrícola en América CentraL. Algunos son remanentes del bosque primario original, Otros son producto de la regeneración natural dentro de los potreros o han sido plantados por los finqueros para la producción de madera o forraje. Los árboles dispersos facilitan la conservación de animales y plantas del bosque dentro del paisaje agrícola, proporcionando importantes hábitats y recursos alimenticios. Estos árboles favorecen la conservac ión y multiplicación de plantas del bosque, debido a que varios animales los visitan regurgitando y defecando semillas, aumentado así la dispersión desde los bosques hacia los campos agrícolas. El estudio se realizó en 24 fincas lecheras en tres comunidades (Santa Elena, Cañitas y La Cruz) ubicadas en Monteverde, Costa Rica (10’18´´N, 84’ 48´´W, 1200- 1350 msnm, 2500 mm de precipitación media anual y 18.5°C de temperatura promedio). Las fincas tienen un promedio de 17 ha; en cada una, se midiero n, contaron e identificaron los árboles dispersos (>2m altura) que se encontraron dentro de potreros. Se concluye que los finqueros de Monteverde han dejado una alta diversidad de árboles dentro de sus potreros, los que son utilizados como fuente de madera, postes, leña y sombra para el ganado principalmente. Muchos de los árboles en los potreros son remanentes del bosque original. -
DocumentOther documentGuayaba en potreros: Establecimiento de cercas vivas y recuperación de pasturas degradadas 1995
Also available in:
No results found.La adaptación de guayaba (Psidium guajava L.) al ambiente de los potreros permite utilizarla en cercas vivas o para recuperar potreros degradados. La agresividad y rusticidad de las plántulas de guayaba pueden aprovecharse para el establecimiento de cercas vivas, que además de delimitar potreros y propiedades, producen leña y frutos. La transformación de pastizales improductivos en áreas reforestadas es un tema de actualidad y la utilización del potencial invasor de los árboles de guayaba, podrí a aprovecharse para este fin.

BookletCorporate general interestEmissions due to agriculture
Global, regional and country trends 2000–2018
2021Also 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. -

No results found.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. -
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.
