Résumé partiel
Climate change – A Global concern
Climate change’ refers to the observed increase in the average temperature of the
air near earth’s surface and oceans in recent decades. Its effect, particularly on
developing countries, is adverse as their capacity and resources to deal with the
challenge are limited. While all people are vulnerable to the impacts of climate
change, those living in low-lying coasts, deltas and resource fragile areas such as
arid and semi-arid regions (dry lands) in India are particularly vulnerable. This is
because, the bulk of people living in these areas draw their sustenance and
livelihood from land, water and biotic resources which would be the first to be
impacted by climate-induced changes. While rising seas will inundate and
submerge these low-lying areas, atmospheric dynamics will subject dry lands to
even more variable and scantier rainfall regimes.
Significance of the study
Vedasandur block has been selected for the present study to assess the impact of
climate change on the farming community. It is a drought prone zone with very
unreliable rainfall which varies from 600 to 800 mm annually and an average
annual rainfall of 791.97 mm. Even this little quantity is not properly collected,
conserved and utilized and hence Vedasandur has become water starved area
which mainly depends on rainfall for crop production. Soil erosion is one of the
major problems in the study area that leads to low organic matter content with
reduced water holding capacity. Lack of irrigation facilities and support services in
water management make farming operation in many parts of the block an exercise
in futility. This study presents the overall problems caused due to climate change
among farming communities in Vedasandur and suggested adaptation measures for
the farmers to cope up with the climate change.
