Due to Unusually heavy rain, coastal storms, or storm surges water resources (river, lake, pond) or water systems(dams) gets flushed with too much water beyond it’s carrying capacity, which overflows to the nearby land causing damage to people and property. Floods may develop slowly or quickly – Flash floods can come with no warning....
Know thy-self, know thy competition, and get it right almost every time. Know thy-self, not know thy competition, and get it right about half the time. Not know thy-self, not know thy competition, and get it wrong almost every time As food is one of the paramount need of humankind, a substantial emphasis has...
Land procurement refers to the process by which the private land is acquired for the purpose of industrialization or expansion of infrastructural amenities by providing compensation to the landowners. Procurement of land for different projects should proceed with minimal socio-economic and environmental impact on the local communities. Environmental impacts of land acquisition need to...
Accurate and faster estimation of crop area is a great utility in the farming process as it helps in estimating crop production in advance of the harvest. As Indian agriculture is mainly characterized by fragmentation and land holdings whose size is less than 1 ha a much finer spatial resolution is necessary. The required...
Accounting for about 70 percent of freshwater withdrawal, irrigation is probably the largest use of water globally. Unlike other uses, only half of the water used for irrigation is reusable. The remaining is lost by evaporation, evapotranspiration, or is lost in transit, by a leaking pipe. With an increasingly scarce water supply, irrigation management...
An aquifer is a water-bearing stratum that releases water in appreciable amounts. Wells are usually drilled into aquifers to fetch water. Aquifers are one of the most important sources of freshwater. Abstraction of groundwater through excessive pumping at a rate faster than it’s recharging rate will result in the overexploitation or persistent depletion of...
With the increase in population, the demand for food is also increasing. The critical challenges in attaining food security include the conversion of agricultural land to built-up land and diminishing agricultural yield due to several factors such as shortage of water, climate change, pests, and other diseases. These issues can be solved to a...
Land degradation is the temporary or permanent loss of ecosystem function and productivity from which the land cannot recover unaided (Bai et al.,2008). Degradation occurs slowly and cumulatively and can exacerbate climate change and threaten agricultural productivity, water quality, among other effects. In India, it is officially estimated that about 44 % of the...
The share of the farm sector in GDP has declined from 29% in 1990 to about 17% in 2016 . The productivity of various crops in the country is less as compared to countries to that some countries in Europe, the US, and China. Crop yield of wheat and rice are less as compared...
The knowledge about the effect of hydrologic and anthropogenic activities on Earth system is of utmost importance as it influences earth’s surface water and energy budgets by altering the near-surface climate, agro-hydrological parameters etc. Many times, the spatial-temporal variation of yield is observed in the same agriculture land because of the spatiotemporal variation of...
