Lake Chilwa
Lake Chilwa, nestled in southeastern Malawi, occupies a depression between the Shire Highlands and the Mozambique border, making it the second-largest lake in Malawi. It extends north-northeast from the foothills of the Mulanje Mountains through Lake Chiuta to the Lugenda Valley in Mozambique, covering 1,000 square miles.聽
Characterized by swamp and mixed savanna vegetation, the lake is a shallow freshwater expanse fed by perennial sources such as the Sombani, Phalombe, and Likangala rivers. The lake undergoes significant seasonal fluctuations, doubling in size during the rainy season and contracting during the dry season, leaving marshes and floodplains.聽
This dynamic landscape profoundly impacts the livelihoods of surrounding communities. Cultivation along the lake margins, particularly with rice in the dry season, is widespread, and commercial fishing is thriving. In the late 1990s, the Danish International Development Agency contributed funds to preserve the wetland environment, improve crop production, and safeguard the diverse flora and fauna of the lake region.
