The sustainability of rice–wheat (RW) production system in the Indo-Gangetic Plains (IGP) of India is being threatened by climate change, and land and water degradation. Conservation agriculture practices provide a nature-based solution by addressing these challenges without affecting food security. In this study, a meta-analysis framework was employed to assess the on-farm economic and environmental impacts of CA in the RW system of the Indian IGP. Results show a higher on-farm yield response of CA in wheat (+5.6%) and a slight reduction in rice yield (–0.4%) compared to conventional tillage (CT). Nevertheless, the Eastern IGP witnessed a positive rice yield (+4.3%) under CA. Carbon sequestration potential of the RW system was found to be significantly higher (+22.70%) in CA. Implementation of CA practices resulted in a substantial reduction of carbon dioxide (–18.80%) and global warming potential (–23.26%). A significant amount of water was saved following CA practices on farms (+19.78%). From an economic point of view, CA practices were found to be more cost-effective with higher net returns compared to conventional tillage in the study region. Outscaling CA represents a win-win strategy for mitigating climate change without affecting food and livelihood security in the region. Providing payment for ecosystem services and developing cost-effective technologies are critical for the outscaling of CA in the IGP.Keywords

The Himalayan ecosystem is one of the most climate change-affected ecosystems in the world. The present study focuses on farmers’ perceptions of climate risks and adaptation strategies in Uttarakhand, mid-Himalaya, India. Using district-level long-term climate data along with village-level surveys, we explored the major trends in climatic variables with farmers’ perception and adaptation practices against climate change vagaries. Farmers noticed changes in the environment that were consistent with trends in the climate data. Farmers’ adaptation measures included changes in crop varieties, reduced number of livestock, shifting to non-farm activities, shifting planting dates and changing the cultivable land size. Stronger extension services, use of mobile advisory for increasing extension contact, inexpensive credit, community-focused agricultural training were the most important factors for effective climate change adaptation behaviour. Farmers’ perception was significantly influenced by number of crops grown, training experience and extension contact. This study emphasizes the need for policymakers to take into account local knowledge of climate change and strategies to speed up communities’ shift towards resilience and the extension mechanism must adapt their strategies for promoting resilience based on locally constrained and unconstrained measures.Keywords
