Crop in Nepal
Downstream impacts of changes in water flow from
high mountain glaciers may affect different aspects of human
livelihoods. The agricultural and food production systems will
be affected by water stress. UNDP (2006) has estimated a 30%
decrease in crop yields in Central and South Asia by the mid
21st century due to increased temperatures and water stress. At
the same time, crop yields may increase at higher altitudes and
latitudes because of decreased frost and cold damage.
