The livestock sector plays a central role in food systems and in the livelihoods of around 1B people

The livestock sector plays a central role in food systems and in the livelihoods of around one billion people, and thus is the subject of plenty of interventions looking at increasing food supply and improving those livelihoods. Traditionally, most efforts have focused on increasing productivity per animal and/or per hectare and a range of technological options, now part of what we call ’sustainable intensification’ have come to dominate the research for development agenda. The Sustainable Development Goals (SDGs) recognize that in the pursuit of food security and further increases in food production, planetary boundaries have to be respected, making sustainability science targets a central part of the development agenda. However, little, if any, attention is placed on the environmental impact of these interventions. This increases the risk of unforeseen negative environmental consequences that could affect vulnerable people in the same region and across the globe.

Project Overview

It uses state-of-the-art modeling approaches, and high-quality global datasets of livestock production systems and their impacts, in combination with information gathered through conversations with the funders, grantees and experts, in order to extract the theory of change behind the intervention and to characterize the production systems before and after the intervention.

The tool currently includes the evaluation of land and water use and greenhouse gas emissions. We are working on integrating the evaluation of other dimensions, like biodiversity and soil health.

MERLIN will be used across the livestock portfolio of the Bill and Melinda Gates Foundation (BMGF), helping to limit or minimize potential negative environmental impacts of their contributions to the agricultural development strategic goals. Furthermore, it will be made available to the wider community, to be used and improved across the sector.
