Introduction
Freshwater resources, which include rivers, lakes, groundwater, and glaciers, are essential for drinking, irrigation, industry, and ecological stability. However, approximately 1.1 billion people lack consistent access to clean drinking water, and around 2.7 billion face recurring water scarcity, highlighting a significant crisis in both availability and access to freshwater resources.
Reasons Behind the Crisis of Availability of Freshwater Resources
- Growing Demand vs. Limited Supply: The global population is projected to increase by nearly 2 billion over the next 30 years, leading to a surge in demand for freshwater while the available supply remains relatively constant.
- Climate Change and Altered Precipitation Patterns: Climate change is causing unpredictable rainfall and prolonged droughts, disrupting the natural replenishment of freshwater sources. For example, in August 2023, India experienced a rainfall shortfall of 36% below normal levels.
- Over-Extraction and Depletion of Aquifers: Many regions are over-pumping groundwater faster than it can be replenished. It is projected that approximately 60% of India’s aquifers will be in a critical state within the next two decades if current patterns persist.
- Pollution and Contamination: Industrial, agricultural, and domestic pollutants make freshwater sources unsuitable for consumption. The World Bank reports that over 80% of wastewater in developing countries is discharged untreated into rivers and lakes.
- Inefficient Water Management: Inadequate infrastructure and wasteful irrigation practices contribute to inefficient use of available freshwater resources. For instance, poorly maintained irrigation systems can waste approximately 25,000 gallons of water annually.
Reasons Behind the Crisis of Access to Freshwater Resources
- Inadequate Infrastructure: Many regions, especially rural and marginalized communities, lack the necessary infrastructure to provide freshwater. For example, the Democratic Republic of Congo, despite having 50% of Africa’s water resources, struggles with access to potable water.
- Economic Disparities: Low-income communities often cannot afford water services. In urban slums of Mumbai, families rely on limited and contaminated water sources due to high costs.
- Political and Social Conflicts: Disputes over water rights can restrict access to shared resources, as seen in the ongoing conflict between Ethiopia, Sudan, and Egypt over the Grand Ethiopian Renaissance Dam on the Nile River.
- Natural Disasters and Conflicts: Events like floods and earthquakes can disrupt water infrastructure, limiting access to freshwater.
- Lack of Education and Awareness: Limited understanding of water hygiene and conservation practices hinders efforts to improve access to freshwater in certain communities.
Conclusion
Addressing the crisis of freshwater availability and access is urgent, given its vital role in sustaining life and socio-economic development. Collaborative efforts and effective management strategies are essential to ensure that clean and accessible freshwater is available for all.

Introduction
Watershed management refers to the strategic management of land and water resources within a watershed to protect and enhance their quality and sustainability. Integrated resource management (IRM) takes a holistic approach by considering the interdependencies between various natural resources. Watershed management plays a crucial role in supporting integrated resource management by balancing and optimizing the use of land, water, and other resources in a coordinated way.
Role of Watershed Management in Integrated Resource Management:
Watershed management ensures that all resources within the watershed are used effectively. By understanding the interconnections between water, soil, vegetation, and wildlife, watershed management enables decisions that promote the sustainable use of resources.
Example: Integrated practices like water-efficient irrigation and crop diversification increase agricultural productivity and optimize water usage in areas with limited water resources.
Watershed management takes into account the entire ecosystem, recognizing that activities in one area of the watershed can affect other areas. This approach helps to balance the needs of different stakeholders, such as farmers, industries, and communities, while protecting the ecosystem.
Example: Riparian zone protection helps reduce soil erosion, stabilize riverbanks, and improve water quality, benefiting both natural ecosystems and human populations.
An essential aspect of watershed management is the involvement of all affected parties. By collaborating, stakeholders can jointly make decisions that benefit the entire watershed, ensuring that resource use is equitable and sustainable.
Example: Community-based programs like Arvary Pani Sansad in Rajasthan encourage local participation in water management, fostering better cooperation and resource sharing.
Watershed management identifies ecologically harmful activities and works to mitigate their impacts. This includes regulating agricultural practices that contribute to water pollution or soil degradation.
Example: The IWMP in India promotes soil conservation measures such as terracing and contour ploughing to prevent soil erosion, improving both land productivity and water quality.
Conclusion
Watershed management ensures the integrated management of natural resources by considering their interconnectedness. It promotes sustainability, balances competing needs, and helps achieve inclusive growth. Successful programs like the Neeru-Meeru initiative in Andhra Pradesh highlight the potential of watershed management to drive positive outcomes in resource conservation and rural development.
