Données sur le projet
The project examined how climate variability and change contribute to changes in aquatic productivity, fisheries, and livelihoods. The project integrating secondary and primary data obtained from two satellite lakes, Wamala in Central and Kawi in North-eastern Uganda. The lakes acted as case studies because they have manifested changes in water levels associated with variability and change in climate. The aim of the project was to mainstream climate change issues into fisheries management in Uganda.

| Identifiant | Project No: 2011 CPR 209 |
| Financement | The project was supprted by the Rockefeller Foundation |
| Description du domaine d'étude / de recherche | The project was implemented on Lake Wamala. Lake Wamala is an environmental change hotspot within the Lake Victoria watershed. The lake has an area of 250 sq. km, an average depth of 5m and a catchment of ≈2000 sq. km. |
| Description du design | Field data collection was conducted on biotic communities including macroinvertebrates to provide field evidence of impacts of climate change on aquatic productivity processes. Representative sites were sampled quarterly in 2012 and 2013. The intention was to obtain data comparable to historical data to deduce shifts in biotic communities attributed to impacts of climate change. |

Méthodes d'échantillonnage
At each site, a sample of macroinvertebrates was collected using a Ponar grab (238 cm2 open-jaw area). Three vertical hauls of sediment at each site were taken. These were mixed to form one composite. Each composite sample was sieved through a 400µm nitex mesh to concentrate the sample. All the samples were placed in labeled sample bottles and preserved with 5% sugar formalin solution for taxonomic identification and enumeration in the laboratory. In the laboratory, the formalin-fixed benthic macroinvertebrate samples were rinsed by tap water to remove preservatives before the sorting of the organisms. All the animals were separated, counted, and identified to the smallest taxonomic level under a dissecting microscope. Appropriate taxonomic keys were used (Mandahl-Barth, 1954; Pennak, 1953; Merritt & Cummins, 1997). Numerical abundance (individuals per square metre, Ind.m-2) was estimated for each taxon.
| Etendue de l'étude | Data was collected between 2012 and 2013 is representative sites, covering near shore, offshore, and river mouths habitats. |
|---|---|
| Contrôle qualité | In the field, samples were immediately treated with formalin to keep the organisms intact. To avoid loss of organisms during sample processing, appropriate mesh sizes during sieving. Appropriate taxonomic keys were used. |
Description des étapes de la méthode:
- In the field, sediment samples were collected using a Ponar grab with an open jaw surface area of 238 cm2. At each site, three sediment samples were obtained. The three samples were mixed and concentrated to form one composite sample for each site.
