Land and Water Use Interactions Emerging Trends and Impact on Land-use Changes in the Tungabhadra and Tagus River Basins
2016
The paper provides a comprehensive analysis of the issues, current status and complex interlinkages
in land and water management, emerging trends and its impact in two river basins1 -
the Tungabhadra sub-basin in India and the Tagus basin in Spain and Portugal. The paper
covers a wide range of issues including changing water demands affected by erratic hydrological
cycles, frequent fires affecting forests, biodiversity and soil thus influencing the livelihoods of
marginal communities. The paper also brings to the forefront the need for integrated water
management in view of poor integration across and within sectors. Therefore, an attempt is
made to understand the dynamics of rain fed and irrigated farming highlighting the technological
and institutional options required for improving water-use efficiency. There is still a long way to
go in both the basins before suitable integration can be achieved leading to an effective
Integrated Water Resource Management strategy.
