Water Access, Water Scarcity, and Climate Change

Water access, water scarcity, and climate change.

This article investigates the approaches of the various discourses operating in the water sector and how they address the issues of scarcity and equitable access under projected climate change impacts. Little synergy exists between the different approaches dealing with these issues. Whilst being a sustainable development and water resources management issue, a holistic view of access, scarcity ...

Multimodel assessment of water scarcity under climate change.

Water scarcity severely impairs food security and economic prosperity in many countries today. Expected future population changes will, in many countries as well as globally, increase the pressure on available water resources. On the supply side, renewable water resources will be affected by projected changes in precipitation patterns, temperature, and other climate variables. Here we use a lar...

Growing sensitivity of maize to water scarcity under climate change

Climate change can reduce crop yields and thereby threaten food security. The current measures used to adapt to climate change involve avoiding crops yield decrease, however, the limitations of such measures due to water and other resources scarcity have not been well understood. Here, we quantify how the sensitivity of maize to water availability has increased because of the shift toward longe...

Water and Climate Change

Are there ecological problems that technology cannot solve? Water scarcity and dams, climate change and biofuels

This paper illustrates through a comparative case study how contemporary engineers working on a technological response to climate change—biofuel production—continue to be guided by traditional ethical and historical principles of efficiency and growth in spite of the uniqueness of climate change as a problem unbounded globally in space and time. The comparative study reveals that in the past en...
