Climate change ' will reduce water for farmers: United Nations (AFP)

ROME (AFP)-l' food Thursday UN Agency warned climate change will limit the availability of water for agriculture in the coming decades, including in the Mediterranean region urged Governments to take measures.

A report by the Food and Agriculture Organization (FAO), said climate change will reduce runoff refills and the aquifer of the River, adding that the loss of glaciers "will ultimately impact on the quantity of available surface water."

The report said that in Asia "large areas of irrigated land-based glaciers from melting snow and the mountain of water are also affected."

She added "densely populated river deltas are exposed to a combination of flows of water, increased sanity and rising waters".

FAO also revealed that while the increased temperatures will extend the growing season in temperate zones of the North that they will be reducing it almost everywhere, leading potential productivity and water of the yield to decline.

It is said that Governments should enhance the capacity of countries to measure their water resources, and to encourage farmers to change their cropping patterns to allow for earlier or later planting and reduce their water consumption.

"Farm size and access to capital set the limits of the scope and extent of adaptation and change at the farm level", said the report.
