Negative Effects of Land Subsidence on Agriculture LAND SUBSIDENCE - WHAT IS IT AND WHY IS IT IMPORTANT? Land subsidence is a condition in which there is a loss of support from water pressure below the ground. As we withdraw ground water and the water table drops‚ the soil collapses‚ compacts‚ and drops resulting in the decrease of land-surface elevation. Subsidence causes permanent inundation of land‚ aggravates flooding‚ changes topographic gradients‚ ruptures the land surface‚ and reduces

Soil Porosity & Density Objective: To determine if the porosity of soil is related to the density. Hypothesis: I think that that the porosity of soil is related to the density because the higher the density of the sand the lower the porosity of the sand‚ which are both componets for the water to rise. Materials: • Sand and Loam samples • 2 large containers • Plastic cups • Water • Scale Procedure: Loam 1) The loam without the water was fresh ‚ it had different shades of black‚ and

Land degradation will remain an important global issue for the 21st century because of its adverse impact on agronomic productivity‚ the environment‚ and its effect on food security and the quality of life. Productivity impacts of land degradation are due to a decline in land quality on site where degradation occurs (e.g. erosion) and off site where sediments are deposited. However‚ the on-site impacts of land degradation on productivity are easily masked due to use of additional inputs and adoption

What is land pollution? Land pollution is the deterioration (destruction) of the earth’s land surfaces‚ often directly or indirectly as a result of man’s activities and their misuse of land resources. It occurs when waste is not disposed off properly‚ or can occur when humans throw chemicals unto the soil in the form of pesticides‚ insecticides and fertilizers during agricultural practices. Exploitation of minerals (mining activities) has also contributed to the destruction of the earth’s surface
