Land Suitability Assessment For Stormwater Management, Mayiladuthurai District, Tamil Nadu

Land is a finite resource, and its uncontrolled and unscientific use can worsen climate change and lead to disasters like droughts and floods. To address these challenges and achieve social, economic, and environmental development goals, responsible and sustainable land-use policies are crucial. Conducting a comprehensive land suitability assessment can guide such practices and policies. As India faces water scarcity for over 600 million people, the National Water Mission (NWM) aims to secure water resources through various programs, including surface and groundwater management and wetland conservation. To mitigate freshwater depletion, storm water management strategies and water harvesting infrastructure should be implemented. A report focusing on Mayiladuthurai district identifies unused lands that could be utilized for storm water management to improve water security, forestation, and agriculture. 

The report analyzes the water harvesting potential of unused lands in Mayiladuthurai district, which encompasses 10% of the total geographical area. The district experiences an annual rainfall of 1,393 mm. The land suitability analysis reveals that 9,816 acres of unused land have the technical potential for storm water harvesting, distributed across 2,179 plots. These lands could capture 84.28 million cubic meters (MCM) of water per year, equivalent to 54% of the set water harvesting target of 156 MCM/year. Most of the plots are suitable for surface water harvesting, which can aid in meeting the district's long-term water security goals.

ENVISIONING TAMIL NADU’S RENEWABLE ENERGY SCENARIOS FOR 2030

Image
Tamil Nadu’s rapid industrial growth and economic development have led to a surge in electricity demand, further fueled by the increasing use of air conditioning (AC) and the adoption of electric vehicles (EVs).   India cooling action plan   anticipates an eightfold rise in nationwide cooling demand by 2037-38, with Tamil Nadu experiencing substantial growth in this regard. Additionally, 2030   NITI Aayog’s ambitious targets   significant EV penetration, shaping the state’s transportation landscape. These shifting demand dynamics present both challenges and opportunities for Tamil Nadu’s electricity sector planning. This report endeavors to forecast the state’s electricity demand in 2030, considering the expected rise in AC and EV usage, thereby providing valuable insights for informed decision-making. In alignment with climate goals, Tamil Nadu aims to derive  50% of its energy from renewable sources   2030, capitalizing on its ample wind and solar resourc...
