The growing menace of pollution, especially plastic is threatening many fragile ecosystems—be it the natural flow of rivers, surface drainage or marine life. The article explores the problem and the consequential damage arising out of dumping about 5 to 13 million tonnes of plastic into the ocean each year.
A total of 19 states in India have introduced a ban on plastic bags. Maharashtra and Uttar Pradesh too have recently joined the fight against plastic waste. However, plastic usage continues unhindered in the absence of rigorous implementation considerably undermining the effectiveness of the ban.
Three humongous landfills of Delhi—Ghazipur, Okhla and Bhalaswa, are way past their capacity. Yet they continue to grow. As their collapse appears imminent with each passing day, threatening to sink the city under its own weight, authorities are suggesting measures for alternative spaces that are clearly not viable.
A June 2018 study published by the National Bank for Agriculture and Rural Development (NABARD) suggests that analysing land productivity of a region and yield of a crop is not sufficient to calculate the efficiency with which water is being used for cultivation. It is also important to analyse whether irrigation water being applied to the crop is resulting in adequate output and if cropping patterns are aligned with water endowments of a region.
In Odisha, where access to piped water supply is low, engaging communities for building their own water supply systems have yielded results that can be emulated on a larger scale.
Presently, the Cauvery River is the city’s sole water source located at a distance of 100 km. But with a population expected to reach 20 million by 2031, the rising demand for water presents unique challenges, calling for participation at all levels.
The answer to India’s perennial drought problem despite high rainfall lies in addressing policy failures and formulating measures not just for mitigating problems, but drought proofing the entire country.
Soil erosion in India Excessive soil erosion in India combined with consequent high rate of sedimentation in reservoirs and decreased soil fertility has led to grave environmental problems. Soil erosion mostly affects practically all kinds of lands such as the forest lands, agricultural lands, arid and semi-arid lands, surface mines, roads, construction sites, coastal areas etc. Further, since soil formation is a very slow process, the erosion of the upper layer of the soil leaves it barren for a long...
Conventional approaches to conservation of groundwater have not considered the need to involve an understanding of aquifer measurement and hydrogeology. Considering India’s diverse geography, it is pertinent to develop a scientific understanding of underlying geology of groundwater resources and how aquifers work.
In colonial India, water ownership became entrenched with the State, a practice that continued post-Independence. For ensuring sustainable and assured supply addressing the needs of communities, decentralised practices such as rainwater harvesting can be beneficial.
