Soil conservation planning on watershed basis Watershed development activity was taken up in the country prior to independence in the state of Maharashtra (then Bombay state) as a scarcity relief work during drought years in which contour binding programme for conservation of moisture and control of soil erosion was mostly undertaken, After independence, … Read more
Scientific Water Harvesting What is Water Harvesting It means capturing rain where it falls or capturing the run off in your own village or town. And taking measures to keep that water clean by not allowing polluting activities to take place in the catchment. Therefore, water harvesting can be undertaken through a variety … Read more
Rainfall: With an Average annual rainfall of 1,170 mm, India is one of the wettest countries in the world. At one extreme are areas like Cherrapunji, in the northeast, which is drenched each year with 11,000 mm of rainfall, and at the other extreme are places like Jaisalmer, in the west, which receives barely … Read more
Wetland Farming: A Sustainable Approach to Agriculture The world’s population is growing, and with it, the demand for food. Conventional agriculture, however, is facing increasing pressure from climate change, resource depletion, and environmental degradation. This has led to a growing interest in sustainable agricultural practices, including wetland farming. Wetland farming, also known as paddy rice … Read more
Waterlogging: A Silent Threat to Global Food Security and Environmental Sustainability Waterlogging, the saturation of soil with water to the point where air is displaced, is a pervasive and often overlooked environmental problem with far-reaching consequences. While often associated with agricultural practices, waterlogging can occur naturally due to heavy rainfall or flooding, or be exacerbated … Read more
The Unseen Threat: Splash Erosion and Its Impact on Soil Health Soil, the foundation of our food systems and ecosystems, is under constant threat from various forms of erosion. While wind and water erosion are often recognized as major culprits, a less visible but equally damaging force lurks beneath the surface: splash erosion. This article … Read more
