About Tamil Nadu SAPCC
SAPCC Overview
Tamil Nadu SAPCC 1.0 was prepared through a Steering Committee, seven sector working groups and public and departmental review. It records its finalisation and formal submission to MoEFCC in July 2014, while the portal metadata lists a 2015 release. The Department of Environment was designated as the nodal department. Its institutional proposals relate to the original five-year implementation period and should not automatically be presented as current arrangements.
Climate profile
- Tamil Nadu includes eastern coastal plains, the hilly Western Ghats and drier central and south-central plains. The Western Ghats restrict much of the southwest monsoon rainfall from reaching the interior and eastern parts of the state.
- The state receives rain from both monsoons. The northeast monsoon supplies the largest share of annual rainfall, making Tamil Nadu's seasonal rainfall pattern different from that of many other Indian states.
- Tamil Nadu SAPCC 1.0 projects continuing increases in maximum and minimum temperatures. It also indicates a slight long-term decrease in total rainfall, accompanied by substantial district-level variation and the possibility of more intense northeast-monsoon rainfall.
- Tamil Nadu's long Bay of Bengal coast is exposed to cyclones, storm surge, coastal flooding, erosion, salinity and sea-level rise. Tamil Nadu SAPCC 1.0 indicates that future cyclones may become more intense even if their overall number decreases.
Climate stress at a glance
- Monsoon failure and rainfall variability affect drinking water, irrigation, agriculture and groundwater recharge, while intense rain can produce urban and coastal flooding.
- The Western and Eastern Ghats, forests, mangroves, wetlands, coral reefs and other coastal ecosystems are important to biodiversity and climate resilience.
- Agriculture, livestock and fisheries are exposed to drought, heat, salinity and changing rainfall.
- Chennai and other growing urban and industrial centres require resilient water, drainage, transport, energy and waste-management systems.
