Innovation Key to Nigerian Start-up to Keep Food Fresh

| Nov. 21, 2022

ColdHubs, an innovative Nigerian agricultural enterprise that uses solar-powered refrigerated storage units to keep food from spoiling, is slowly but surely expanding to nearby West African countries. But it faces big challenges to scale up and finance its operations, company founder and CEO Nnaemeka Ikegwuonu told a Harvard Kennedy School audience celebrating the 2022 Roy Award winner.

Climate change, especially the variability of rainfall patterns, poses a threat to maize production in Ghana. Some farmers harvest rainwater and store it for maize production to cope with unpredicted rainfall patterns. However, there are only a few studies on the adoption of rainwater harvesting for maize production. This study analyses the factors that influence farmers' decision to harvest rainwater for maize production in Ghana.

Forests, Trees, and Agroforestry: Their Roles in India's Sustainable Development and Climate Action

| May 2022

This research note provides insights on the role of nature-based solutions for carbon mitigation in India, including scenario simulations by 2050. The results show that forests, trees, and agroforestry can provide major carbon reductions through sustainable land use nationwide, helping India to offset carbon emissions from hard-to-abate sectors.

Arctic Innovation Lab: Bright Ideas for the Future of the Arctic

| Mar. 14, 2022

What if we could repurpose oil and gas pipelines to supply remote Arctic communities with clean water? What if Arctic entrepreneurs could connect with investors and raise capital over an online crowdfunding platform? These were some of the novel solutions to Arctic challenges proposed by Harvard Kennedy School students during this year’s Arctic Innovation Lab in January.

Mexico’s Energy Reforms: A Blow to Realizing the Most Competitive and Dynamic Region in the World

| Feb. 28, 2022

In late 2017, Mexico made headlines as Italian company Enel bid what was then a world-record low price for renewable energy in the country’s third such energy auction. This development was possible due to the historical and sweeping energy reforms passed with broad support in Mexico in 2013. Then-President Enrique Peña Nieto had succeeded where previous Mexican presidents had failed, reversing decades of resource nationalism and overhauling the energy sector through constitutional reforms that gave the private sector a larger role and advantaged renewable energy in Mexico’s economy. The 2017 auction seemed to indicate Mexico’s bright future not only as a conventional oil producer, but also as a clean energy power.

Energy Generation in the Canal Irrigation Network in India: Integrated Spatial Planning Framework on the Upper Ganga Canal Corridor

| December 2021

An extensive canal irrigation network in South Asia has developed over the past 170 years that consists of thousands of kilometers of constructed channels and distributaries. These canals cut across many energy-poor regions along their paths. In India, this canal network provides a unique opportunity for renewable energy generation that is yet to be realized.
