Short description of the intervention
The Nyashishi wetland is located on the western side of Lake Victoria some 15 km from Mwanza, a port city of the lake. The area is characterized by a double maxima rainfall, with heavy rains occurring during October to December. The wetland is traversed by the Nyashishi River, which is an intermittent river draining stormy waters and domestic waste water into Lake Victoria. Increased human socio-economic activities in Mwanza, such as horticulture, overgrazing and discharge of industrial effluents, have degraded the Nyashishi wetland. As a result, vegetation specifically elephantiasis and papyrus that used to flourish in the wetland and provide fish breeding grounds have disappeared. The crocodiles, large lizards and a host of other creatures that used to populate those areas cannot be seen today. Since the wetland and the river are part of the Lake Victoria Basin, both have been subjected to floods and droughts, impacting livelihoods, public health and the environment. The root causes of floods are irregular seasonal and year to year variability in rainfall patterns, combined with mismanagement of land and water resources, leading to soil erosion and increased run-off. Therefore restoration efforts in the area are much needed. (1, 5)

Goals of the intervention
The project's primary objective was to contribute to the conservation of Nyashishi wetland with the view of restoring fish breeding grounds and prevent biodiversity loss under a vision of fighting climate change, and protecting and restoring natural biodiversity for social economic sustainability. This project also intended to contribute to the restoration of the Nyashishi wetland through strong advocacy, awareness creation actions, grass seeding and planting of indigenous trees.In this sense, the specific objectives of the intervention were:
1. Reducing the destruction of the wetland
2. Reduction of the soil erosion (in direct connection with agricultural work in the region)
3. Creating awareness for the marginalised communities that inhabit the area
4. Empowering local communities in environmental activities.
5. Enhancing capacity building for fisherfolks to manage marine resources in a sustainable manner
6. Plant indigenous trees (1,2,3)

Quantitative targets
Restoring 1200 ha of wetland of which 500 ha are permanent swamp
Serving approx. 20,000 people directly (in the peri-urban communities) and approx. 1 mil. people indirectly (in the urban area) (3,4)

Implementation activities
The wetland has two distinct components: an extensive floodplain and a permanent swamp abutting the waters of the Mwanza Gulf. The Wetland is compact, surrounded by hills, with a relatively well-defined edge. It has one obvious seasonal river inflow, the Nyashishi River, subtending two different vegetation zones, i.e. that of the floodplain vegetation and that of the permanent swamp. The surrounding communities have converted the seasonal wetland to agricultural and grazing land.
The project activities started in February 2014 and ended in December 2015. They included: organisation of workshops with the involvement of the communities in the area and planting native local trees involving local people (the number of trees is not mentioned in the sources). The objective in planting trees was to establish a forestation process applicable to the area, considering local species and climatic conditions (1,2).

Comments and notes
Additional insights
The NGO who staged the intervention mentioned that there were a series of challenges to address:
1. Low level of voluntary spirit leading to high cost of operational costs.
2. Lack of proper organization of civic groups working on the Lake Victoria Basin wetlands.
3. Wetland environmental aspects.
4. Scarcity of resources to meet the actual project and other operational costs. (2)

The United Nations Development Program (UNDP) website mentions that the intervention was completed satisfactorily but does not provide more information. (1)
