Brochure, flyer, fact-sheetBrochureNota informativa de la FAO sobre el gusano cogollero del maíz en África 2017El gusano cogollero del maíz (Spodoptera frugiperda) es una plaga de insectos que se alimenta de más de 80 especies de cultivos y causa daños a cereales cultivados de importancia económica –como el maíz, el arroz y el sorgo– y también a las leguminosas, así como a los cultivos de hortalizas y al algodón. Es nativo de las regiones tropicales y subtropicales de las Américas, y la polilla adulta puede trasladarse más de 100 km por noche. Deposita sus huevos en las plantas, de las cuales comienzan a alimentarse las larvas una vez han eclosionado. Las infestaciones fuertes pueden generar pérdidas significativas de rendimiento. En las Américas, los agricultores vienen manejando la plaga desde hace años, pero con costos considerables.

Book (series)Technical reportStatus and Prospects for Smallholder Milk Production
A Global Perspective
2010Also available in:
In 2005, some 1.4 billion people lived in absolute poverty and that nearly 1 billion were affected by chronic mal- or undernutrition. An estimated 75 percent of the world’s poor live in rural areas, and at least 600 million of these keep livestock that enable them to produce food, generate cash income, manage risks and build up assets. With the valuable contribution that livestock makes to sustaining livelihoods, especially in rural areas, the development of small-scale livestock enter prises could be a key element of efforts to eradicate extreme poverty and hunger. Milk production is an important livestock-sector activity and it is estimated that nearly 150 million farm households throughout the world are engaged in milk production. Small-scale milk production not only improves food security of milk producing households but also creates significant amounts of employment in the entire dairy chain, which comprises many small-scale rural processors and intermediaries . On the other hand, demand for milk and milk products is steadily growing, particularly in developing countries. If supply is to keep pace with the growth in demand, milk production will need to grow by close to 2 percent per year. -

Book (series)Manual / guideA guide to forest–water management 2021Many people worldwide lack adequate access to clean water to meet basic needs, and many important economic activities, such as energy production and agriculture, also require water. Climate change is likely to aggravate water stress. As temperatures rise, ecosystems and the human, plant, and animal communities that depend on them will need more water to maintain their health and to thrive. Forests and trees are integral to the global water cycle and therefore vital for water security – they regulate water quantity, quality, and timing and provide protective functions against (for example) soil and coastal erosion, flooding, and avalanches. Forested watersheds provide 75 percent of our freshwater, delivering water to over half the world’s population. The purpose of A Guide to Forest–Water Management is to improve the global information base on the protective functions of forests for soil and water. It reviews emerging techniques and methodologies, provides guidance and recommendations on how to manage forests for their water ecosystem services, and offers insights into the business and economic cases for managing forests for water ecosystem services. Intact native forests and well-managed planted forests can be a relatively cheap approach to water management while generating multiple co-benefits. Water security is a significant global challenge, but this paper argues that water-centered forests can provide nature-based solutions to ensuring global water resilience.
