Soil erosion is one of the most serious environmental and public health problems facing human society. Humans obtain more than 99.7% of their food (calories) from the land and less than 0.3% from the oceans and other aquatic ecosystems. Each year about 10 million ha of cropland are lost due to soil erosion, thus reducing the cropland available for food production. The loss of cropland is a serious problem because the World Health Organization reports that more than 3.7 billion people are… 

Soil Erosion Threatens Food Production

Since humans worldwide obtain more than 99.7% of their food (calories) from the land and less than 0.3% from the oceans and aquatic ecosystems, preserving cropland and maintaining soil fertility

Soil Erosion and Conservation in Global Agriculture

About one-sixth of the world’s land area, that is, about one-third of the land used for agriculture, has been affected by soil degradation in the historic past. While most of this damage was caused

Understanding Land Degradation: An Overview

Much of the Earth’s population has become dependent on agriculture as it provides food for the sustenance of animals including man. Land and climate determine to a great extent successful crop

The analysis of the mechanism of soil erosion is given, based on which the situation of soil eroded and the current conservation of it in China is further analyzed.

Input constraints to food production: the impact of soil degradation

Global demand for food is increasing in terms of the quantity, quality and reliability of supplies. Currently, over 90 % of our food is grown on (or in) a virtually irreplaceable, non-renewable

A review on soil erosion conservation measures in Nepal

Soil erosion is one of the most serious environmental problems in Nepal. It has resulted to the loss of agricultural crops and top soil every year. Different soil conservation techniques are being

Controlling Soil Erosion Using No-Till Farming Systems

Soil erosion is a natural phenomenon that has been thrown off balance by human activity and particularly by agriculture. It is associated with severe environmental impacts, high economic costs,

Soil and Water Conservation

Soil is the most fundamental and basic resource. Although erroneously dubbed as “dirt” or perceived as something of insignificant value, humans can not survive without soil because it is the basis of

Wildlife in the perspective of environmental degradation: A review

After the existence of an organism, it strives hard to live in its surrounding environment. All the animals interact with its environment for energy gain and loss, to protect itself, and for all



Ecology of Soil Erosion in Ecosystems

ABSTRACT Each year, about 75 billion tons of soil are eroded from the world's terrestrial ecosystems. Most agricultural land in the world is losing soil at rates ranging from 13 tons/ha/year to 40

Environmental and Economic Costs of Soil Erosion and Conservation Benefits

With the addition of a quarter of a million people each day, the world population's food demand is increasing at a time when per capita food productivity is beginning to decline.

Water Resources: Agricultural and Environmental Issues

The increasing demands placed on the global water supply threaten biodiversity and the supply of water for food production and other vital human needs, and new water supplies are likely to result from conservation, recycling, and improved water-use efficiency rather than from large development projects.

Erosion and soil productivity in Africa

ASIA probably has suffered more from human-induced soil erosion than any other continent. As one of the first to describe the impacts of erosion on early civilizations, Walter Lowermilk noted the

ABSTRACT Soil erosion has both on-farm and off-farm impacts. Reduction of soil depth can impair the land's productivity, and the transport of sediments can degrade streams, lakes, and estuaries.

Water Resources: Agriculture, the Environment, and Society

This paper analyzes consumption of water by individuals agriculture and energy production by assessing the status of water resources and the relationship between water availability and biodiversity and concludes that the freshwater problem can be prevented.

The carbon sink capacity of the world's agricultural and degraded soils is 50 to 66% of the historic carbon loss of 42 to 78 gigatons of carbon. The rate of soil organic carbon sequestration with

Managing U.S. cropland to sequester carbon in soil

The effects of human activities on atmospheric concentrations of carbon dioxide (CO2) and other greenhouse gases (GHGs) are under intensive study in the United States and worldwide. Since conversion

Soil erosion and productivity research : A regional approach

Soil erosion is occurring at an alarming rate and threatens soil productivity and crop growth. A regional research committee was formed in the North Central region of the US in 1983 to develop a
