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. -
Book (stand-alone)Report of the regional workshop on salt-affected soils from sea water intrusion: strategies for rehabilitation and management 2005
Also available in:
No results found.The 26 December 2004 earthquake and tsunami devastated the lives of millions. With considerable determination, local communities have joined national and international organizations and governments to bring relief and start the recovery work. FAO has been involved in assisting the affected countries in numerous ways so that agricultural activities may be resumed. While short-term assistance is indispensable, strategic planning for medium and long-term rehabilitation in collaboration with partner s and governments is required for appropriate intervention. To strengthen regional coordination and collaboration in support of rural development and food security, the above workshop was organized in Bangkok, Thailand from 31 March to 1 April 2005. The overall goal was to enhance rehabilitation efforts for the reclamation of salt-affected soils in tsunami-affected areas and to identify suitable management practices for sustainable crop production. A major outcome of the workshop was a regional strategic framework for coordinating the actions to be taken at the regional level for the rehabilitation and reconstruction of the affected areas. -
Book (stand-alone)Proceedings of the Second Meeting of the International Network of Salt-Affected Soils (INSAS)
Managing salt-affected soils for a sustainable future
2023Also available in:
No results found.The proceedings of the second meeting of the International Network of Salt-Affected Soils (INSAS) contain the abstracts of the papers presented during the workshop in Tashkent (22–26 May, 2023). The papers provide the up-to-date scientific knowledge and practical solutions for four topics: (1) mapping, assessing and monitoring of salt-affected soils; (2) sustainable management of salt-affected soils: practices and policy; (3) halophyte and saline agriculture and its effect on soil health; (4) integrated soil and water management under saline/sodic conditions.Under the first topic, modern techniques (geophysics, remote sensing, NIR spectroscopy) for mapping and monitroing of salt-affected soils as wel as mapping of environmental susceptibility to soil salinization in dry regions were presented. Under the second topic, different approaches to reclaim saline and sodic soils and improve seed germination including the use of different organic and inorganic amendments, organic biostimulants, biochar and phytoremediation were discussed. Moreover, biodiversity of salt-affected soils and its change along salinity gradient as well as the impact of soil enzymes on the structure and function of soil microbial communities and how soil degradation is associated with specific soil microbiota were reported. Policy gaps on addressing soil salinity were analyzed and further steps how to integrate agenda on SAS into existing agricultural policies were proposed. The results of Participatory Rural Appraisal approach to survey among farmers were provided. Under the third topic, the results on testing different conventional and non-conventional crops in field trials on salt-affected soils irrigated by fresh and saline water were reported. The influence of soil properties on growing halophytes was considered. Under the fourth topic, the ways to optimize the use of poor-quality irrigation water in agriculture were discussed. Some studies reported about the results of modeling of salt and water transport in soils for estimation of leaching requirement or root zone soil salinity. Several studies reported about the negative aspects of using brackish water leading to secondary soil salinization and sodification. For salt-affected areas with groundwater use for irrigation, the approach combining the Food Systems Approach and integrated water resources management was proposed to address the interdependent challenges of food and water security.
