Saline Agriculture for Climate Adaptation (SACA) Malawi

对于马拉维的农村社区来说，土地退化以及气候变化和自然灾害的影响是主要的生计挑战。奇夸瓦地区特别容易受到环境压力的影响，因为它比该国其他地区更干燥、更低、更干旱。地下水和土壤中的盐分威胁着该地区本已紧张的耕地资源和植被。我们的创新恢复了退化的土地，将盐碱化的土壤变成了高利润和健康的生态系统，而不需要使用任何淡水。我们通过使用传统井和现代井眼中的咸水地下水来做到这一点，这些井眼随着时间的推移已经变成了盐分，或者那些已经被挖掘到咸水沉积物中的地下水。虽然这些“盐井”可能不再使用，但由于它们的高含盐量，本项目利用它们来建设基于生态系统的咸水农场，在这些农场中，营养作物和水产养殖以循环生产模式结合在一起。过去两年，SACA马拉维延续了该小组在孟加拉国和越南等国领导的项目，这些项目解决了类似的威胁，并实施了创新的土地管理做法，以综合修复盐井，以恢复退化的土地，并创建能够增强农村社区气候适应能力的宝贵生态系统。

For rural communities in Malawi land degradation and the impacts of climate change and natural hazards are key livelihood challenges. The region of Chikwawa is especially prone to environmental strains as it is dryer, lower, and more arid than other regions of the country. Salinity in groundwater and soils threatens the region's already strained arable land resources and vegetation.Our innovation restores degraded land, turning salinized soils into highly profitable and healthy ecosystems without using any freshwater. We do this by using saline groundwater from traditional wells and modern boreholes which have become saline over time, or those that have been dug into deposits of saline water. While these 'saline wells' may no longer be in use, due to their high salinity levels, this project uses them to build ecosystems-based saltwater farms in which nutritious crops and aquaculture are combined in circular production models.SACA Malawi follows on from projects led by the team in the last two years in countries like Bangladesh and Vietnam which addresses similar threats, and implements innovative land management practices for the integrated restoration of saline wells to restore degraded land, and create invaluable ecosystems that strengthen the climate resilience of rural communities.
