Over the coming decades, a changing climate, growing global population, increasing incomes, changes in food choices, rising food prices, and environmental stressors, such as increased water scarcity and land degradation, will have significant yet uncertain impacts on food security. There are different aspects having direct links to meeting food security at the global level, including globalization of markets. Growing per capita incomes in emerging economies such as Brazil, China, India and Russia imply additional pressure on global food production due to changing food habits. Increased food production has to come from the available and finite water and land resources that are declining in quality (Wani etal., For example, in India, the per capita water availability has declined from 5 177 m3 in 1951 to 1 820 m3 in 2001, with the population increasing from 361 million in 1951 to 1.02 billion in 2001. India’s population is expected to rise to 1.39 billion by 2025 and to 1.64 billion by 2050, with associated reductions in per capita water availability of 1 341 m3 by 2025 and 1 140 m3 by 2050.
