Abstract/ Executive Summary:

Development was conventionally driven by one particular need, without fully considering the wider or future impacts. This kind of approach has now been considered to be responsible for the economic and environmental catastrophes that humans are facing: from large scale financial crises caused by irresponsible banking to the changes in global climate resulting from our dependence on fossil fuel based energy sources. Soils provide essential ecosystem services such as primary production, regulation of biogeochemical cycles (with consequences for the climate), water filtration, resistance to diseases and pests, and regulation of above-ground biodiversity. Changing of the climate systems is unequivocal. Adaptation to global climate change through improved soil quality by adoption of improved management practices is key to maintaining sustainable agricultural production. A holistic approach to soil management as the engine for increasing productivity by increasing resource use efficiency and making agriculture environmentally compatible is more important than ever before. Strategies of greenhouse gas emission reduction include those that increase the use efficiency of inputs. Herein, we discussed how management and protection of soil resources can contribute to sustainable development through sustainable agricultural production while maintaining sustenance of soil fertility.

Achievement/Findings:

Sustainable agriculture needs to protect the natural resource base, prevent the degradation of soil and water; conserve biodiversity; contribute to the economic and social well-being of all; ensure a safe and high-quality supply of agricultural products; and safeguard the livelihood and well-being of the nation. The world now faces modern soil crisis that eclipses those of the past. The challenges that agriculture is facing in sustainable development are working out ways of bringing about a society that is materially sufficient, socially equitable and ecologically sustainable and one that is not obsessed by growth only, but motivated by satisfying human needs and equity in resource allocation and use. Soils are crucial resources for sustainable development and need to be managed and protected. Sustainable agriculture must nurture healthy ecosystems and support the sustainable management of soil resources while ensuring global food security and environmental safety. In order to adequately address the utterly important role of soils for sustainable development a holistic approach is needed. Sustainable development can be possible by an integrated approach of soil management to address the social, economic and environmental dimensions. Soil carbon should be linked with soil function not only as a potential mechanism for climate change mitigation but also with fundamental provision of food, fibre, water and biodiversity provides insights into a far broader set of environmental, economic and social outcomes for the planet. Adaptation to climate change can be enhanced through mulch farming, agroforestry systems, INM, and soil water conservation. Improved soil management practices for economic, social and environmental sustainability require combating desertification, soil erosion assessment, soil fertility enhancement, fertilizer evaluation and soil conservation measures and adopting integrated soil-crop-water management package to increase crop productivity in harsh environments. Agricultural package comprising of reduced tillage, cover crop, crop rotation, INM and application of organics can be best soil management and protection tool.
