Soil Ecology: Remote Sensing and Geographic Information System in Management

Ecosystem Management and Conservation of Soil Ecology is an extremely important and complex issue; and this require integrated approach. The fast urbanization and industrialization due to heavy migration in the Delhi (study area) have resulted in the loss of fertile soil and thus have changed fertility, productivity and bio-diversity because soil and land have disturbed the ecosystem. Accelerated soil degradation and erosion is a serious global problem that is widely recognized. Sustainable soil management is not possible without water, land and soil conservation, well planning and development because soil is a complex system where its productivity and fertility depends upon physical, chemical and biological reactions. The present study demonstrate a conservation approach which opens ways for sustainability of resources through mapping, estimation and assessment and the applicability of remote sensing and Geographic Information system (GIS) to assess and estimate for management of degraded soil for sustainable Development. Sustainable soil management is a complex process. There is no soil management without water resources management. The concept, criteria and meaning of sustainable development & bio-diversity are explained. Degradation and structural aspects of soil, impact of urbanization and industrialization, management economics and possible strategies and discussed. Management of soil toxicology is a challenging job. Soil fertility (nutrients) assessment in terms of N,P,K, etc., pH and conservation approach for management of degraded soil, hydromorphology, groundwater level status, generation of integrated map for suitable site for water management through check dams in GIS (Modular GIS Environment) system for sustainable water management etc. has been explained.
