This chapter investigates the widespread and unchecked environmental abuse in India. Nearly a third of India’s land area has been degraded through deforestation, over-cultivation, soil erosion, and depletion of wetlands. Reckless industrialization, mining, and urbanization, as well as deeply flawed agricultural policies and skewed land distribution have reaped a bitter harvest of dislocation and deprivation. This dispossession adds to India’s historically unequal land holdings. Along with the poisoning of life-giving water and air, land alienation and destruction create a hierarchy of citizens suffering unequal access to the fundamental ingredients of social life. The destruction of the elements by the entanglement of the state and big business, and the priority given to private profit over public good, have contributed to the systematic evisceration of democracy-defining social equality. The chapter raises the important question of whether people can be said to have the same right to vote and enjoy equal social dignity if they don’t have the same right to breathe or have equal access to water.

Vinh Linh, the northern district of Quang Tri province is characterized by a diversified topography with a large variety of elevations, high rainfall, and decreasing land cover due to forest exploiting for cultivation land. Thus, there is a high risk of erosion, soil fertility washout. With the support of GIS technology, the authors used the rMMF model to measure soil erosion. The input data of model including 15 coefficients related to topography, soil properties, climate and land cover. The simulations of rMMF include estimates of rainfall energy, runoff, soil particle detachment by raindrop, soil particle detachment by runoff, sediment transport capacity of runoff and soil loss. The result showed that amount of soil loss in year is estimated to vary between 0 kg/m2 minimum and 149 kg/m2 maximum and is divided into 4-classes of erosion. Light class almost covers the region researched (75.9% of total area), while moderate class occupies 8.1% of total area, strong classes only hold small area (16% of total area). Therefore, protection of the forest floor in sloping areas is one of the most effective methods to reduce soil erosion.

The article considers the issues of solving the problems of the development of the erosive danger of soil in Azerbaijan, which is why it should be understood that the human mind is unable to change the force of nature, but can only learn and correctly use the laws of nature, use the acting natural force and improve the ways of controlling them. At the same time, in the process of development, methods are struggling with soil erosion in the first stage, which is necessary for studying the causes of occurrence and patterns in its development

the presented research is dedicate to confirming the hypothesis about increase in extreme precipitation of recent decades, affecting the degree of soil erosion in crop rotations.
