Focal point
Location
The Food and Agriculture Organization of the United Nations leads international efforts to defeat hunger. Serving both developed and developing countries, FAO acts as a neutral forum where all nations meet as equals to negotiate agreements and debate policy. FAO is also a source of knowledge and information. We help developing countries and countries in transition modernize and improve agriculture, forestry and fisheries practices and ensure good nutrition for all. Since our founding in 1945, we have focused special attention on developing rural areas, home to 70 percent of the world's poor and hungry people.

This publications presents a methodology and software for assessing carbon sequestration that were developed and tested in pilot field studies in Mexico and Cuba. The models and tools enable the analysis of land use change scenarios in order to identifyin a given area (watershed or district) land use alternatives and land management practices that simultaneously maximize food production, maximize soil carbon sequestration, maximize biodiversity conservation and minimize land degradation.
Report of the FAO/OXFAM GB Wokshop on Women's Land Rights in Southern and Eastern Africa
The report summarises the papers, presentations and discussions of a workshop on failures and achievements at securing women’s land rights. In particular, it addresses the following issues: Land rights and legal reforms,legal aid and land administration practice, women's land rights in an HIV/AIDS context,women's land rights from a food security and livelihoods context. Organised by the FAO and Oxfam, the workshop seeks to establish global and multi-sectoral alliances and multiple strategies as a means of breaking out of the present impasse in this matter.
Global estimates of gaseous emissions of NH3, NO and N2O from agricultural land
Plants take up only 50 percent of the nitrogen fertilizer applied to agricultural land. Part of this inefficiency is a result of emissions of ammonia (NH3), nitrous oxide (N2O) and nitric oxide (NO). Quantifying these emisions is important, both as part of an attempt to improve fertilizer use efficiency and because of their influence on ecosystems, atmospheric pollution and the so-called greenhouse effect. This report provides a comprehensive review of the literature about emissions of NH3, N2O and NO, and examines the regulating factors, measurement techniques and models.
Impact of shrimp farming on arable land and rehabilitation of resultant salt-affected soils/integrated soil management for sustainable use of salt-affected soils
The development of agricultural technologies and a better appreciation of the existing but under-utilised knowledge of resource management will be crucial in meeting the ecological needs and in achieving the anticipated food demands of the growing population in the future. The greatest challenge for the coming decades lies in the fact that the production environments are unstable and degrading. Land degradation is proceeding so fast that unless policies and approaches change, many countries will not be able to achieve sustainable agriculture in the foreseeable future.
Guidelines: land evaluation for extensive grazing
Extensive grazing is the predominant form of land use on at least a quarter of the world’s land surface, in which livestock are raised on food that comes mainly from rangelands. Extensive grazing differs from crop or forestry production, in which the produce remains in situ whilst growing. Evaluation for extensive grazing, unlike that for cropping or forestry, must take into account the production of both grazing forage, termed primary production, and the livestock that feed on this forage, termed secondary production.
