Abstract:
Continuous and unabated land degradation in India is a threat to agricultural sustainability while increasing temperatures, changing rainfall patterns and precipitation intensification are going to further aggravate degradation in future. The timely adoption of integrated land and water conservation technologies minimises erosion and provides significant adaptation and mitigation co‐benefits. The objectives of this study were to assess the mitigation potential of soil and water conservation technologies and also the feasibility of making villages carbon positive. The extent of minimisation of soil loss due to soil conservation technologies ranges from 0.10 to 21.65 Mg ha −1 yr −1 , while carbon emissions minimised range from 0.73 to 158.77 kg ha −1 yr −1 . Emission minimisation from various water management technologies in rice ranges from 73.0 to 507.9 kg CO 2 equivalents ha −1 yr −1 . Agroforestry practices can sequester 8.64 to 52.77 Mg CO 2 ha −1 yr −1 besides enhancing system productivity, arresting soil erosion and carbon loss through erosion. Integration of multiple technologies in a farming system further enhances the adaptation and mitigation benefits. Adoption of conservation technologies resulted in a net carbon balance of 0.05–1.23 CO 2 Mg ha −1 yr −1 in 9 villages in India, indicating net positive carbon balance due to reduction of greenhouse gas emissions and carbon sequestration. Building carbon positive villages is a potential approach for preventing land degradation, while enhancing productivity, mitigating climate change and realising the sustainable development goals. Building capacities of communities and establishing institutions in villages are essential for upscaling and maintaining of soil and water conservation structures and community assets in the village. Furthermore, prioritisation and scaling of location specific land and water conservation technologies hold the key to establish carbon‐positive villages.
