Drought In India
Drought in India has resulted in tens of millions of deaths over the 18th, 19th, and 20th centuries. Indian agriculture is heavily dependent on the country's climate: a favorable monsoon is critical to securing water for irrigating India's crops. In parts of India, failure of the monsoons causes water shortages, resulting in poor yields. This is particularly true of major drought-prone regions southeastern Maharashtra, northern Karnataka, Andhra Pradesh, Odisha, Gujarat, Telangana, and Rajasthan. History Only about 35% of total agricultural land in India is irrigated and two-thirds of cultivated land is entirely dependent on rainfall. As such, the agricultural production system in the country is more vulnerable to damage from extreme climatic events, which causes increased water stress leading to inadequate water supplies for irrigation. Already, rises in average temperatures, changes in rainfall patterns, increasing frequency of extreme weather events, such as severe droughts ...

El Niño–Southern Oscillation
El Niño–Southern Oscillation (ENSO) is an irregular periodic variation in winds and sea surface temperatures over the tropical eastern Pacific Ocean, affecting the climate of much of the tropics and subtropics. The warming phase of the sea temperature is known as ''El Niño'' and the cooling phase as ''La Niña''. The ''Southern Oscillation'' is the accompanying atmospheric component, coupled with the sea temperature change: ''El Niño'' is accompanied by high air surface pressure in the tropical western Pacific and ''La Niña'' with low air surface pressure there. The two periods last several months each and typically occur every few years with varying intensity per period. The two phases relate to the Walker circulation, which was discovered by Gilbert Walker during the early twentieth century. The Walker circulation is caused by the pressure gradient force that results from a high-pressure area over the eastern Pacific Ocean, and a low-pressure system over Indonesia. Weak ...

Interstate River Water Disputes Act
The Interstate River Water Disputes Act, 1956 (IRWD Act) is an Act of the Parliament of India enacted under Article 262 of Constitution of India on the eve of reorganization of states on linguistic basis to resolve the water disputes that would arise in the use, control and distribution of an interstate river or river valley. Article 262 of the Indian Constitution provides a role for the union government in adjudicating conflicts surrounding interstate rivers that arise among the state/regional governments. This Act further has undergone amendments subsequently and its most recent amendment took place in the year 2002. River waters use / harnessing is included in states jurisdiction (entry 17 of state list, Schedule 7 of Indian Constitution). However, the union government with parliament approval can make laws on regulation and development of interstate rivers and river valleys to the extent such water resources are directly under its control when expedient in the ...

Indian Rivers Interlinking Project
The Indian Rivers Inter-link is a proposed large-scale civil engineering project that aims to effectively manage water resources in India by linking Indian rivers by a network of reservoirs and canals to enhance irrigation and groundwater recharge, reduce persistent floods in some parts and water shortages in other parts of India.Jayanta Bandyopadhyay and Shama Perveen (2003)The Interlinking of Indian Rivers: Some Questions on the Scientific, Economic and Environmental Dimensions of the Proposal IIM Calcutta, IISWBM, Kolkata India accounts for 18% of the world population and about 4% of the world’s water resources. One of the solutions to solve the country’s water woes is to link rivers and lakes. The Inter-link project has been split into three parts: a northern Himalayan rivers inter-link component, a southern Peninsular component and starting 2005, an intrastate rivers linking component. The project is being managed by India's National Water Development Agency Minist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Groundwater
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater in the world is groundwater. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, perma ...

Dissolved Load
Dissolved load is the portion of a stream's total sediment load that is carried in solution, especially ions from chemical weathering. It is a major contributor to the total amount of material removed from a river's drainage basin, along with suspended load and bed load. The amount of material carried as dissolved load is typically much smaller than the suspended load, though this is not always the case, particularly when the available river flow is mostly harnessed for purposes such as irrigation or industrial uses. Dissolved load comprises a significant portion of the total material flux out of a landscape, and its composition is important in regulating the chemistry and biology of the stream water. The dissolved load is primarily controlled by the rate of chemical weathering, which depends on climate and weather conditions such as moisture and temperature. Dissolved load has many useful applications within the field of geology, including erosion, denudation, and reconstructing c ...

Kalpasar Project
The Kalpasar Project or the Gulf of Khambhat Development Project envisages building a 30 km dam across the Gulf of Khambat in India for establishing a huge fresh water coastal reservoir for irrigation, drinking and industrial purposes. The project with 30 km sea dam will have the capacity to store 10,000 million cubic meters fresh water, equating to 25% of Gujarat’s average annual rainwater flow, from the rivers like Narmada, Mahi, Dhadhar, Sabarmati, Limbdi-Bhagovo, and two other minor rivers. A 10 lane road link will also be set up over the dam, greatly reducing the distance between Saurashtra and South Gujarat. The project, which will create world's largest freshwater lake in marine environment, will cost INR90,000 crore or US$12.75 billion (2015-16 estimates with 8% annual inflation) excluding the cost of tidal power plant. Project entails construction of the main ''"Kalpasar dam"'' across Gulf of Khambat and another Bhadbhut barrage on Narmada river, as wel ...

Peak Water
Peak water is a concept that underlines the growing constraints on the availability, quality, and use of freshwater resources. Peak water was defined in a 2010 peer-reviewed article in the ''Proceedings of the National Academy of Sciences'' by Peter Gleick and Meena Palaniappan. They distinguish between peak renewable, peak non-renewable, and peak ecological water in order to demonstrate the fact that although there is a vast amount of water on the planet, sustainably managed water is becoming scarce. Lester R. Brown, president of the Earth Policy Institute, wrote in 2013 that although there was extensive literature on peak oil, it was peak water that is "the real threat to our future".Brown, Lester R"Peak Water: What Happens When the Wells Go Dry?" ''Earth Policy Institute, July 9, 2013'' An assessment was published in August 2011 in the Stockholm International Water Institute's journal. Much of the world's water in underground aquifers and in lakes can be depleted and thus re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Change In India
Climate change in India is having profound effects on India, which is ranked fourth among the list of countries most affected by climate change in 2015. India emits about 3 gigatonnes (Gigatonne, Gt) Carbon dioxide equivalent, CO2eq of greenhouse gases each year; about two and a half tons per person, which is less than the world average. The country emits 7% of global emissions, despite having 17% of the world population. Temperature rises on the Tibetan Plateau are causing retreat of glaciers since 1850, Himalayan glaciers to retreat, threatening the flow rate of the Ganges, Brahmaputra, Yamuna and other major rivers. A 2007 World Wide Fund for Nature (WWF) report states that the Indus River may run dry for the same reason. Heat waves' frequency and intensity are increasing in India because of climate change. Severe landslides and floods are projected to become increasingly common in such states as Assam. Climate change performance index of India ranks eighth among 63 countries wh ...

List Of Cleanest Cities In India
The Ministry of Urban Development, Government of India, and the Central Pollution Control Board (CPCB) of India, annually publish National City Rating under the Swachh Bharat Abhiyan scheme. The rating includes around 500 cities, covering 72 percent of the urban population in India. Until 2017, India was divided into five zones for the purpose of this survey and each city was scored on 19 indicators. The cities were classified into four colours: green, blue, black, and red, green being the cleanest city, and red the most polluted. None of the cities was rated as green—the best category in the exercise. However, during the 2017-18 senses survey, the parameters of assessment were modified, and cities were categorised, based on population, into metropolis, large, medium, and small cities, and assessment took place according to this categorisation. The latest ranking of 2022 by the cleanliness survey ''Swachh Survekshan'' marks Indore as the cleanest city of India. Indore has he ...
