Hydrological regimes, including inter- and intra-annual water level fluctuations, are key drivers of productivity and structure in freshwater ecosystems in Africa, where inland fisheries are a vital source of income and protein. Using a synthesis of seventeen standardized food web models of thirteen African lakes and reservoirs, this study explored the relationship between inter- and intra-annual water level fluctuations and sixteen ecological attributes associated with ecosystem configuration, productivity and maturity.

Indicator 6.6.1 tracks changes over time in the extent of water-related ecosystems. It uses the imminent date of 2020 in order to align with the Aichi Targets of the Convention of Biodiversity, but will continue beyond that date to align with the rest of the SDG Targets set at 2030. Whereas all ecosystems depend on water, some ecosystems play a more prominent role in the provision of water-related services to society. Consequently, one of the focuses for global monitoring of this indicator is lakes.

Population, Health, and the Environment (PHE) is a community-based development model that uses integrated approaches to improve access to health services, especially family planning and reproductive health, while helping communities manage natural resources and conserve the critical ecosystems on which they depend. PHE is a last mile approach that reaches vulnerable populations in rural areas that are typically beyond the reach of government services and large-scale development projects. For over two decades, diverse organizations around the world have carried out PHE projects.

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.

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.

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 Economics of Land Degradation (ELD) Initiative focuses on the economic benefits of land and land-based ecosystems. The initiative highlights the value of sustainable land management and provides a global approach for analysis of the economics of land degradation. It aims to make economics of land degradation an integral part of policy strategies and decision making by increasing the political and public awareness of the costs and benefits of land and land-based ecosystems.
