Soil is a living, naturally occurring dynamic system at the interface of air and rock. Soil forms in response to forces of climate and organisms that act on parent material in a specific landscape (topography) over a period of time. Soil is the most fundamental and basic resource. Although erroneously dubbed as “dirt” or perceived as something of insignificant value, humans cannot survive without soil because it is the basis of all terrestrial life. Soil and land, whether it is biomass in the form of food, feed, bio energy, or biomaterials, play a crucial role in today’s life and underpin global efforts towards sustainable development. It underpins food security and environmental quality, both essential to human existence. Essentiality of soil to human well-being is often not realized until the production of food drops or is geopardised when the soil is severely eroded or degraded to the level that it loses its inherent resilience. Management and conservation of soil resources is critical to human well-being. Their prudent use and management is more important now than ever before to meet the high demands for food production and satisfy the needs of an increasing world population. Despite the extensive research and abundant literature on soil conservation strategies, concerns of worldwide soil degradation and environmental pollution remain high.
