Climate change can have severe consequences for South Asia
WASHINGTON: South Asian crop yields could fall
by as much as 30 percent by the middle of the century on account of
global warming, according to a new report issued by the World Bank.
Other findings say that glacier melting in the Himalayas is projected
to increase flooding and will affect water resources within the next
two to three decades. Climate change will compound the pressures on
natural resources and the environment due to rapid urbanisation, industrialisation,
and economic development. Mortality due to diarrhoea, primarily associated
with floods and droughts, will rise. Sea-level rise will exacerbate
inundation, storm surge, erosion and other coastal hazards. The impact
of these changes, says the report, will be quite devastating. The
consequences for the poor include: decreased water availability and
water quality in many arid and semi-arid regions, an increased risk
of floods and droughts in many regions, reduction in water regulation
in mountain habitats, decreases in reliability of hydropower and biomass
production, increased incidence of waterborne diseases such as malaria,
dengue, and cholera, increased damages and deaths caused by extreme
weather events, decreased agricultural productivity, adverse impacts
on fisheries and adverse effects on many ecological systems. The World
Bank report said that as a result of these changes, climate change
could hamper the achievement of many Millennium Development Goals,
including those on poverty eradication, child mortality, malaria,
and other diseases, and environmental sustainability. Much of this
damage would come in the form of severe economic shocks. In addition,
the impact of climate change will exacerbate existing social and environmental
problems and lead to migration within and across national borders.
