Water rights from which river are already claimed, limiting irrigation?

• A. Nile River
• B. Zambezi River
• C. Usutu River
• D. Limpopo River

Answer: (C)

Water rights and licenses determine how much water can be drawn from a river. If rights are already claimed by existing users, there isn’t free water left to allocate for new irrigation without violating agreements or harming ecosystems. In the southern African context, the Usutu River basin already has established licenses and allocations tied to existing uses, including cross-border arrangements with South Africa and current irrigation schemes. Those pre-existing rights mean there is limited water available for additional irrigation projects, so irrigation development on this river is constrained by those existing claims.

Rivers like the Nile, Zambezi, and Limpopo have their own sets of agreements and uses, but in this scenario the Usutu River is the one where the water has already been allocated to other users, making it the limiting factor for expanding irrigation.
