crops effect from climate change
this era of rapid climate change the importance of climate projections in policy making,
resource management, economic activity and technological advancement cannot be denied.
Information about changes in climate change and variability is required to better anticipate
potential impacts of climate change on the water resources, agriculture, energy, economic,
health, industrial and private sectors. Global warming is bringing lot of interactive changes to the
physical processes responsible for the climate system dynamics. Such changes, sometimes,
appear as occurrence of extreme events of unprecedented intensity casting irreversible loss to the
natural resources. Pakistan is one of the most vulnerable countries to the consequences of the
climatic change because of its diverse geographical and climatic features. The north of Pakistan
hosts more than 5000 glaciers while the south is composed of hyper deserts despite the closet
vicinity of the Arabian Sea. Precipitation and temperature gradients are converse of each other as
winter and summer precipitation concentrates in the northern half. The upstream and
downstream interaction, under increasing frequency and intensity of extreme hydrological
events, makes the Indus Delta highly risky zone for sustainable crop production.
This is the first comprehensive report linking global changes to Pakistan’s climate system
dynamics including the future climate projections at the finest temporal and spatial resolutions
for temperature and precipitation. Almost all climate change related risks likely for the Indus
Deltaic are discussed in detail backed by scientific evidence based on the output of Global
Climate Models. I believe that the report will help the scientists, researchers, planners and policy
makers to devise future strategies for climate change impact assessment and adaptation in
various sectors of vital interest for the economy of Pakistan. For future climate projections, mild
climate change scenarios are selected because lots of efforts are underway by the global
community to develop consensus on curtailing the emission levels of Green House Gases
to optimum limits. Although, there are uncertainties in the outputs of Global Climate
Models (errors much enhanced on centurion scale) yet the decadal outputs may be of great value
