Saline Agriculture for Climate Adaptation (SACA) Malawi

对马拉维农村社区来说，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。Chikwawa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。我们的创新可以恢复退化的土地，在不使用任何淡水的情况下将盐渍化土壤转化为高利润和健康的生态系统。我们通过使用来自传统威尔斯井和现代钻孔的含盐地下水来做到这一点，这些钻孔随着时间的推移已经变成含盐的，或者那些已经被挖到含盐地下水沉积物中的地下水。虽然这些“盐水威尔斯”可能不再使用，由于其高盐度，该项目使用它们来建立基于生态系统的盐水农场，其中营养作物和水产养殖结合在循环生产模式中。SACA马拉维是该团队在过去两年中在孟加拉国和越南等国家领导的项目的后续，这些国家解决了类似的威胁，执行创新的土地管理做法，综合恢复盐碱威尔斯，以恢复退化的土地，并创造宝贵的生态系统，加强农村社区的气候适应能力。

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.
