Abstract
Small-scale fisheries in Kenya support more than 1.5 million livelihoods but face mounting climate and market shocks that threaten food security and income stability. Research led by Duke University and the University of Nairobi evaluated the Keep IT Cool model—a private enterprise linking fishing communities around Lake Victoria and Lake Turkana to higher value markets trough solar-powered cold storage and logistics. Results show that access to cooling reduced post-harvest losses, improved nutritional diversity, and strengthened households’ ability to recover from shocks, though short-term income effects remain modest. The findings highlight the importance of pairing cold-chain technologies with financial tools and policy supports that lower capital costs and make resilience an investable outcome.

Marc A. Jeuland
Marc Jeuland is a Professor in the Sanford School of Public Policy, with a joint appointment in the Duke Global Health Institute. His research interests include nonmarket valuation, water and sanitation, environmental health, energy poverty and transitions, trans-boundary water resource planning and management, and the impacts and economics of climate change.
Jeuland's recent research includes work to understand the economic implications of climate change for water resources projects on transboundary river systems, a range of primary data collection projects related to analysis of adoption of environmental health improving technology, and analysis of the costs and benefits of environmental health interventions in developing countries. He has conducted multiple field experiments on issues such as: the role of water quality information in affecting household water and hygiene behaviors; the demand for, and impacts of cleaner cookstoves on household well-being; the long-term sustainability and effects of rural sanitation and water supply projects. He has also collected data on preferences for a range of environmental health improvements including cholera vaccines, household water treatment technologies and improved cookstoves. In the energy and development domain, he is currently working on several projects with the Energy Access Project at Duke, and is a co-founder of the Sustainable Energy Transitions Initiative (SETI), along with Professor Subhrendu Pattanayak and scholars from Chile, China and Ethiopia. His energy portfolio includes work related to evaluation of cleaner cooking interventions, measuring energy access and reliability, and reviews of the drivers and impacts literature related to energy.
Jeuland has worked in the past with the World Bank, USAID, the Millennium Challenge Corporation, UNICEF, and many field-based NGOs and community-based implementing organizations.
Prior to his graduate studies and work with the World Bank, Jeuland was a Peace Corps volunteer in Mali, West Africa, where he designed and monitored construction of a pilot wastewater treatment system and trained management personnel at the plant’s managing firm.
