Points to Remember:
- Total potential capacity involves assessing both surface water and groundwater resources.
- Chhattisgarh’s geography and rainfall patterns significantly influence its water resources.
- Data availability and accuracy are crucial for reliable evaluation.
- Sustainable management practices are essential for long-term water security.
Introduction:
Chhattisgarh, a state in central India, possesses significant water resources, crucial for its agricultural economy and overall development. Evaluating the total potential capacity of its surface and groundwater requires analyzing various factors, including rainfall, river systems, aquifer characteristics, and existing water usage. Accurate assessment is challenging due to data limitations and the dynamic nature of water resources. However, various government reports and studies provide insights into the state’s water potential. The assessment needs to consider both the renewable and non-renewable aspects of these resources.
Body:
1. Surface Water Resources:
Chhattisgarh’s surface water resources are primarily fed by the Mahanadi River system and its tributaries. The Mahanadi basin covers a significant portion of the state. The total surface water availability varies considerably depending on the monsoon season. Several major and minor rivers and reservoirs contribute to the state’s surface water potential. However, uneven distribution across the state, coupled with seasonal variations, poses a challenge. Data from the Central Water Commission (CWC) or state water resources department would be crucial for quantifying the total potential capacity of surface water, including potential for irrigation, hydropower generation, and domestic use. The potential is further impacted by factors like water loss due to evaporation and seepage.
2. Groundwater Resources:
Chhattisgarh has extensive groundwater resources, primarily confined to alluvial aquifers in the plains and fractured rock aquifers in the hilly regions. The Central Ground Water Board (CGWB) conducts regular assessments of groundwater potential. Their reports would provide data on the total groundwater recharge, storage capacity, and sustainable yield. However, over-exploitation in certain areas, particularly for agriculture, has led to declining water tables in some regions. The quality of groundwater is also a concern, with issues of salinity and fluoride contamination reported in some areas. A detailed analysis of aquifer characteristics, recharge rates, and current extraction rates is necessary to accurately assess the total potential capacity of groundwater resources.
3. Challenges and Limitations:
- Data Scarcity: Comprehensive and reliable data on both surface and groundwater resources in Chhattisgarh may be limited. Data collection and monitoring need improvement.
- Uneven Distribution: Water resources are not evenly distributed across the state, leading to regional disparities in availability.
- Over-exploitation: Over-extraction of groundwater for irrigation and other purposes has led to depletion in some areas.
- Water Quality: Issues of water quality, including salinity and contamination, affect the usability of water resources.
- Climate Change: Climate change impacts, such as altered rainfall patterns and increased frequency of droughts, pose a significant threat to water security.
Conclusion:
Determining the precise total potential capacity of surface and groundwater in Chhattisgarh requires a comprehensive and integrated assessment using data from various sources, including the CWC and CGWB. While the state possesses substantial water resources, uneven distribution, over-exploitation, and water quality issues pose significant challenges. A sustainable water management strategy is crucial, incorporating measures like rainwater harvesting, efficient irrigation techniques (drip irrigation, sprinkler irrigation), groundwater recharge, and watershed management. Strengthening data collection and monitoring systems is essential for informed decision-making. Promoting water conservation awareness among the public and implementing stringent regulations to prevent over-exploitation are vital for ensuring long-term water security and sustainable development in Chhattisgarh, aligning with the principles of holistic development and environmental sustainability.
