This publication presents a meta-analysis of global scientific literature with the aim to develop a clear understanding of the impacts and benefits of the two most common types of agriculture, traditional tillage agriculture and Conservation Agriculture with respect to their effects on soil carbon pools.
Conservation scientists and foresters manage the overall land quality of forests, parks, rangelands, and other natural resources.
4. SOIL CONSERVATION 4.1 PRINCIPLES 4.1.1 The Extent of Erosion. The lower rainfall in semi-arid areas compared with that in humid climates does not mean a corresponding low level of soil erosion by water.
Erosion in the context of soil and watershed conservation is the detachment and movement of soil particles by natural forces, primarily water and wind.

Soil erosion is a serious problem arising from agricultural intensification, land degradation and other anthropogenic activities. Assessment of soil erosion is useful in planning and conservation works in a watershed or basin.
In this lesson, students study the availability of fresh water on Earth and the methods that can be used to purify and conserve it. They also assess how much water they and their families typically use and think about ways to reduce water usage ...
Salinity Concentration of dissolved salts found in a sample of water. Measured as the total amount of dissolved salts in parts per thousand.
1. Introduction  The supply of freshwater that supports human health and enterprise is basically constant, representing only about 1% of the water available worldwide.
Effects of conservation tillage on soil properties vary, and these variations depend on the particular system chosen. No-till (NT) systems, which maintain high surface soil coverage, have resulted in significant change in soil properties, especially in the upper few centimeters (Anikwe & Ubochi, 2007).
Water is a vital part of the natural world. The lives of animals, plants and people depend on healthy water sources.
5. WATER CONSERVATION. This chapter deals with methods to increase the amount of water stored in the soil profile by trapping or holding rain where it falls, or where there is some small movement as surface run-off.

Conservation tillage refers to a number of strategies and techniques for establishing crops in a previous crop's residues, which are purposely left on the soil surface (see Figure 1 and Figure 2).
The California bearing ratio (CBR) is a penetration test for evaluation of the mechanical strength of natural ground, subgrades and base courses beneath new carriageway construction.
Tillage is the agricultural preparation of soil by mechanical agitation of various types, such as digging, stirring, and overturning. Examples of human-powered tilling methods using hand tools include shovelling, picking, mattock work, hoeing, and raking.
