|Description=Inland aquatic ecosystems, including rivers, natural lakes, reservoirs, and wetlands, cover about 8 to 9% of the Earth’s continental surface ([[Lehner and Döll, 2004]]). The wetland area has declined considerably in the last century ([[Moser et al., 1998]]). Freshwater systems are dynamic and spatially interrelated , and the drivers of biodiversity loss partly differ from those of terrestrial ecosystems (see Section 7.2). Therefore, the effects of human-induced changes on the biodiversity of freshwater aquatic ecosystems is covered in a separate model in the IMAGE framework. | |Description=Inland aquatic ecosystems, including rivers, natural lakes, reservoirs, and wetlands, cover about 8 to 9% of the Earth’s continental surface ([[Lehner and Döll, 2004]]).

Key policy issues
- How will the biodiversity in freshwater bodies develop in the absence of additional policies and measures?
- What are the key pressure factors causing loss of aquatic biodiversity?
- How will policies and measures to reduce the key pressure factors contribute to meeting the internationally agreed targets of the UN Convention on Biological Diversity (CBD)?
