Biodiversity, Crop Yields & Climate Change

Climate risks pose unprecedented risks to agricultural food production. Farmers cope with climate risks through adjustments in farm management practices. In recent years, Climate-Smart Agriculture (CSA) has also been proposed as a framework to manage climate risks. Transformations in agricultural landscapes due to changes in farm management or through the adoption of new CSA technologies are likely to affect agricultural biodiversity, and in turn, food system sustainability and resilience. Understanding of how farm-level management practices and CSA affect biodiversity is poor, yet it is crucial for identifying the trade-offs and synergies among food production, biodiversity, and food system sustainability under climate change in order to inform a more sustainable and resilient food system of the future.

In this GCRF-AFRICAP seminar, Dr Hemant Tripathi unpacks AFRICAP’s agroecology research on the effects of farm management and CSA practices on invertebrate diversity and crop yields in the East Usambara Mountains of Tanzania. He will provide insights into the ecological implications of CSA and traditional farm management at the local and landscape scales. The future of crop pests and diseases, associated crop yield losses, and biological control mechanisms under different land, climate, and trade scenarios in Africa will also be discussed. The event will close with a response from seminar discussant Sina Luchen (FAO), followed by an audience Q&A, facilitated by the event chair, Dr Susannah Sallu.

Register to attend Biodiversity, Crop Yields & Climate Change on Thursday 27 May from 13:30 – 14:45 (BST).



Dr Hemant Tripathi, Research Fellow in African Agricultural Ecology, University of Leeds 

Hemant is a postdoctoral fellow in African agroecology at the University of Leeds. As part of GCRF-AFRICAP’s agroecology team in the UK, South Africa and Tanzania, his research focuses on evaluating the effects of farm-level management practices on invertebrate communities. Specifically, he studies the implications of conservation and climate-smart agriculture practices on food production, biodiversity, crop pests and natural enemies. He also collaborates with other interdisciplinary AFRICAP researchers to understand the socio-ecological aspects of agricultural systems, such as how farmers respond, cope and adapt to environmental shocks like drought and COVID-19.
