Cage fish farming is growing fish in net enclosures suspended in water at high density in low volume (LVHD) or low density in high volume (HVLD) cages while maintaining free water exchange between the enclosure and the water body. Cage fish farming has increased in the African Great Lakes (AGL) region, since the beginning of the 21st century and has in less than 20 years, demonstrated capacity to increase fish production to more than 40 kg m-3 compared to ~5 kg m-3 from ponds which started more than 60 years ago.
Commitments to deliver climate finance to developing countries are longstanding. Developed countries pledged to deliver finance approaching $30 billion between 2010 and 2012, in the context of a commitment to mobilise $100 billion per year from public and private sources by 2020 in the Copenhagen Accord of 2009. These commitments were affirmed in the Cancun Agreements of 2010.
While fish catches in Lake Victoria are declining mainly from overfishing and pollution, demand for fish protein has been on a gradual increase as a result of rapid human population growth. To bridge the gap, aquaculture production mainly in ponds and tanks has tremendously increased. Recently, cages have sprung in Lake Victoria, Kenya to augment the growing demand.
The African Great Lakes region has been experiencing extreme rainfall. Sometimes, it might result in floods or it might be very dry weather. But by 2050 the whole region will be experiencing significant changes in the water cycle. Water is the lifeblood of this region with large lakes and rivers. The state of water resources affects all natural, social and economic systems. Water serves as the fundamental link between the climate system, human society and the environment. Climate change is severely impacting the hydrological cycle and consequently, water management in the region.
Lake Malawi in the Africa Great Lakes region is one of the deepest lakes in the world. The total number of fish species in Lake Malawi is estimated at approximately 15% of the global total of freshwater species and approximately 4% of the worlds fishes. Particularly noteworthy are the high diversity of haplochromine cichlids. It is listed as a world heritage site due to its outstanding universal values. Lake Malawi is about 586 km long and 16-80 km wide covering 20% of Malawis earth surface.
The TerrAfrica Partnership leverages funds to scale up sustainable land management in sub-Saharan Africa. It is a regional initiative to help African countries develop harmonised and programme-based initiatives in sustainable land and water management (SLWM). TerrAfrica also works to improve coordination between African governments, the international development community and other global and regional stakeholders. The programme contributes to realising the objectives of CAADP and the Action Plan of the NEPAD Environment Initiative.
The Nile Basin Initiative (NBI) is a partnership of the riparian states that has been active since 1999. It seeks to develop the river in a cooperative manner, share substantial socioeconomic benefits, and promote regional peace and security through its shared vision of sustainable socioeconomic development through the equitable utilization of, and benefit from, the common Nile Basin water resources. The NBI is based in Entebbe, Uganda and includes Burundi, Democratic Republic of Congo, Egypt, Ethiopia, Kenya, Rwanda, Sudan, Tanzania and Uganda.
The Niger Basin Authority (NBA) works to ensure integrated development of the Niger Basin in the fields of energy, water resources, agriculture, animal husbandry, fishing and fisheries, forestry, transport, communications and industry. NBA Member States include the following countries that border the Niger River: Niger, Benin, Chad, Guinea, Cote d 'Ivoire, Mali, Nigeria, Cameroon and Burkina Faso.
The East African Community has designated Lake Victoria and its Basin as an "area of common economic interest" and a "regional economic growth zone" to be developed jointly by the Partner States. Lake Victoria is the focus of new attention following the declaration by the East African Community Heads of State that a joint programme be developed for the overall management and rational utilization of the shared resources of the Lake.
