Book (stand-alone)Impact of shrimp farming on arable land and rehabilitation of resultant salt-affected soils/integrated soil management for sustainable use of salt-affected soils 2000
Also available in:
No results found.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. Soil salinization has been identified as a major process of land degradation. The greatest technical causes of decreasing production on many irrigated projects particularly in arid-semi-arid areas, or failure of large areas in rainfed agriculture, are waterlogging, salinization and sodication. -
MeetingRegional Workshop on Management of Salt-Affected Soils in the Arab Gulf States

No results found.Salinity is a global problem highly affecting 20 to 30 million ha., rendering them unfit for food production. According to FAO, as much as double that area is classified as "less affected" by salinity but remains vulnerable and susceptible to improper irrigation practices, deforestation, overgrazing and other abuses. In arid and semi-arid areas, such as in the Near East Region, irrigation plays an important role in the overall agriculture sector by producing over 1/3 of the agricultural output. In some countries where rainfall is scanty, irrigated areas are the backbone of their agricultural activity and the main contributors to food security. In its Continuous efforts to combat hunger, F AO recently launched the "Food For All Campaign. Irrigation was given prime attention in the Campaign's Special Programme for Food Security (SPFS). Soil conservation/rehabilitation, water harvesting and small scale irrigation schemes also figured in prominently in SPFS. The present volume documents fo r the "Regional Workshop on Management of Salt-Affected Soils in the Arab Gulf States". The F AO Regional Office sponsored the workshop in response to a request made by the Gulf States themselves. It is our hope that the review of the latest on monitoring and evaluating the effects of salinity would contribute positively to national activities. Especially in adopting feasible practices to combating soil and water salinization. -
Book (stand-alone)Thematic 1: Farmers’ guidelines on soil and water management in salt-affected areas 2023
Also available in:
No results found.The threats posed by salt-affected soils to global food security are dire. According to the recent Global salt-affected soils map, over 424 million hectares of topsoil (0–30 cm) and 833 million hectares of subsoil (30–100 cm) are currently salt-affected. This practical guide to soil and water management in salt-affected areas provides vital information to farmers dealing with salinity and sodicity issues on their farms and assists them in following suggested practices to mitigate or/and to adapt to these unfavourable conditions without compromising further losses in yields.
