Globally, agriculture accounts for some 70% of global water diversions, and the agricultural sector is the single largest consumer of water in most countries. In addition, water used in agriculture is typically considered to have lower economic value than when applied for “new” uses. As a result, the agricultural sector is often the loser when pressures for reallocation occur, both because it has the most to give and because reallocation away from agriculture can increase overall water productivity.

In addition, farmers must continue to find ways to maintain incomes and meet their livelihood needs.
