Conference Themes: Soil erosion is one of the main forms of land degradation. Area under cultivation is 21.59 m.ha. Ongoing spatial and temporal measurements of greenhouse gases at both point and regional scales is important for clarification of climate change mechanisms and accounting. Soil is loosely defined, by scientists and environmental agencies, as the ‘physically altered top 1.2m of the earth’s crust’.1 Indeed, the British Society of Soil Science calls it ‘the dynamic skin of the earth’2: this dynamism comes from the interaction of the different components of soil, including minerals, organic materials and living organisms. 0000015629 00000 n It addresses the implications of soil erosion with emphasis on global hotspots and synthesizes available from developed and developing countries. The amount is of course important to the overall hydrologic cycle and replenishment of the soil water, and the amount is an accumulation or product of the intensity times the duration. Farmyard manure, green manure and composts etc. Surface shear strength, represented by the penetration depth of fall-cone penetrometer, appeared to be a key factor involved in this process. Crop yields and income increased with, integrated land and water conservation appr, source of income is fruit trees. About 1.68% of the areas (4714 ha) in the river basin were identified with moderate to high erosion severity (>5 t ha ⁻¹ year ⁻¹ ) class which urgently need measures to control soil erosion. 0000062537 00000 n About this page. Importance of soil. Lands with moderate to high soil erosion classes were mostly found in Bulathsinghala , Kuruwita , and Rathnapura divisional secretarial divisions. With the addition of a quarter of a million people each day, the world population's food "Principles of Soil Management and Conservation" comprehensively reviews the state-of-knowledge on soil erosion and management. Conservation of soil and water resources is important for sustainability of agriculture and environment. The increased frequency and severity of climate related hazards and risks induced by climate change are adding a new dimension to the existing disaster risk profile of India. 2.
