It has led to drying up of water wells and streams and lowering of the water table like in Butaleja, Pallisa and Iganga were Naigombya, Lumbuye and Mpologoma swamps have been reclaimed. This in turn is leading to the spread of the negative environmental phenomenon of desertification.
It has led to a change in water quality of such swamps and wetlands. Also since wetlands act as a filter to lakes, their reclamation increases water pollution into lakes like Victoria affecting aquatic life.
It has led to change in climatic regimes since swamp reclamation reduces rainfall received like in Pallisa and Iganga. This has discouraged crop growing and famine and drought are beginning to hit such places.
Reclamation of swamps affects the life of thousands of marine animals and plants whose habitat has been removed. Foristance reclaiming of Kachido and upper Murchison bay wetlands, Lutembe wetland has affected crested cranes and migrant birds from Europe hindering tourism.
The practice has led to floods in areas of Bwaise and Kalerwe, Kyambogo and Nakawa, etc. this has resulted into water borne diseases like dysentery, bilharzia and cholera in such areas of Kampala.
Reclamation affects the source of building materials such as papyrus, sand and clay. This has resulted into high costs of building materials and construction like clay bricks from Kajjansi, Lweza and Kawempe are expensive.
Swamp reclamation increases the rate of siltation of rivers and streams like in Walukuba, Makenke, and Magamag. Also the reclamation of Doho and Kibimba swamps has led to siltation of R. Manafa thus floods and loss of aquatic life.
It leads to reduction in fishing grounds.
Lowering of the water table which leads to drying up of streams and wells.
Leads to easy spread of diseases since it causes pests invasion.
