Many studies in Africa use the river basin as a unit of analysis at scale and adopt sophisticated model-based techniques to assess climate change impacts on hydrology under different climate and development scenarios, thereby presenting trade-offs between competing uses such as hydropower generation, irrigation and ecosystem requirements ( [[#9.12.1|Section 9.12.1]] ; [[#Yang--2018|Yang and Wi, 2018]] ; [[#Ahmed--2020|Ahmed, 2020]] ). However, longer (multi-decadal) hydrological datasets and model improvements are required ( [[#Taye--2015|Taye et al., 2015]] ), and models should incorporate the quantification of the wider benefits, risks and political opportunities arising from reservoir development to better inform decision makers to achieve a higher level of (transboundary) cooperation ( [[#Digna--2016|Digna et al., 2016]] ; [[#Nijsten--2018|Nijsten et al., 2018]] ). Collaboration between scientists and policymakers to address the complexity of decision making under uncertainty ( [[#Steynor--2016|Steynor et al., 2016]] ) ( [[#Pienaar--2017|Pienaar and Hughes, 2017]] ), coupled with community involvement in participatory scenario development and participatory GIS to aid in collaborative planning that is context specific ( [[#Muhati--2018|Muhati et al., 2018]] ; [[#Álvarez%20Larrain--2019|Álvarez Larrain and McCall, 2019]] ) are powerful tools for more beneficial adaptive and resilience-building actions.
