India ranked the second highest for the rate of deforestation after losing almost 660000 hectares of forest cover in the last 30 years as per studies. Deforestation has significant effects on both the environment and the pattern of agriculture in India.
India ranked the second highest for the rate of deforestation after losing almost 660,000 hectares of forest cover in the last 30 years as per studies. Deforestation has significant effects on both the environment and the pattern of agriculture in India.
Causes of Deforestation in India:
- Agricultural Expansion:
- One of the primary causes of deforestation.
- With a growing population and increasing demand for food, there is pressure to clear forests to make way for cultivation.
- For example, in states like Madhya Pradesh and Chhattisgarh, forests are being cleared to make room for agricultural activities such as rice cultivation and cash crops like soybean.
- Illegal Logging and Timber Extraction:
- Commercial and illegal logging for timber and wood products contributes to deforestation, particularly in states like Assam, Arunachal Pradesh, and Kerala.
- Urbanization and Infrastructure Development:
- Rapid urbanization and infrastructure development, including the construction of roads, highways, dams, and industrial facilities, result in the clearing of forests.
- For example, the construction of the Polavaram Dam in Andhra Pradesh and the expansion of cities like Mumbai and Delhi have led to significant deforestation in their surrounding areas.
Effects of Deforestation in India:
- Loss of Biodiversity:
- Deforestation results in the loss of biodiversity as it destroys habitats for numerous plant and animal species.
- India, with its rich biodiversity, suffers from the loss of endemic species due to deforestation. For example, the Western Ghats, a biodiversity hotspot, is facing significant habitat loss due to deforestation for agriculture and urbanization.
- Soil Erosion and Degradation:
- The removal of forest cover exposes the soil to erosion by wind and water, leading to soil degradation and reduced fertility.
- For example, in states like Uttarakhand and Himachal Pradesh, deforestation has resulted in soil erosion, landslides, and loss of agricultural land.
- Water Resources Disruptions:
- Forests act as natural watersheds, regulating the flow of water and maintaining hydrological cycles.
- Deforestation disrupts these cycles, leading to changes in water availability and quality.
- For example, in states like Rajasthan and Gujarat, deforestation in the Aravalli Range has resulted in reduced groundwater recharge and water scarcity, affecting agricultural practices in the region.
Impact of Deforestation on Agriculture:
- Loss of Agroecological Diversity:
- Deforestation reduces agroecological diversity by eliminating forests that provide valuable ecosystem services such as pollination, pest control, and soil fertility maintenance.
- This loss of biodiversity affects crop yields and agricultural resilience to pests and diseases.
- Changes in Microclimate:
- Deforestation alters local microclimates, leading to changes in temperature, humidity, and rainfall patterns.
- These changes can affect crop suitability and productivity, influencing the choice of crops grown in a particular region.
- For example, deforestation in the Western Ghats has led to changes in rainfall patterns, affecting the cultivation of crops like coffee and spices in the region.
- Water Management Issues:
- Deforestation disrupts hydrological cycles and watersheds, leading to changes in water availability for irrigation.
- This can result in water scarcity or excess water, both of which negatively impact agricultural productivity.
- For example, in states like Punjab and Haryana, deforestation has contributed to groundwater depletion, affecting the sustainability of agriculture in these regions.
Progressive Steps Taken by the Indian Government to Combat Deforestation in India:
National Afforestation Programme, National Mission for a Green India, Compensatory Afforestation Fund Management and Planning Authority, Joint Forest Management, and Sub-Mission on Agroforestry are progressive steps taken by the Indian government to combat deforestation in India.
