Digital Earth Partnership Technology Challenge

Get the chance to work with the World Bank to explore the use of your innovative technologies to better measure and assess the Urban Heat Island effect in the East Asian region


This year, the World Bank is increasingly concerned about the impact of extreme heat on East Asian countries and has embarked on the EAP Regional Extreme Urban Heat Study to better assess the impacts of extreme heat exposure in the region and to inform city-level strategies to mitigate and adapt to such negative impacts. To support this study, SSTL and the World Bank, with the support of the Global Facility for Disaster Reduction and Recovery (GFDRR), are launching the Digital Earth Partnership Technology Challenge to source solutions from companies and research organizations to better measure temperatures in cities and analyze the strength of the UHI effect in the region. Satellite data should be used to augment or support the final solution.


Like the rest of the world, Asia is getting warmer due to climate change. As urbanization and climate change progress, extreme heat in cities will become an even more widespread and urgent problem. The Urban Heat Island (UHI) effect, which is caused mainly by the modification of land surfaces due to urbanisation, is exacerbating this trend. The removal of trees and other green spaces to make way for buildings and roads, the addition of heat-absorbing materials, and waste heat from energy use in buildings and transportation are adding to the already rising ambient temperature.

Urban heat results in reduced productivity, worse education and health outcomes, and greater energy requirements for cooling, leading to more carbon emissions, and also correlates with increased crime, conflict, domestic violence, and poorer mental health. The UHI effect disproportionately impacts poor or otherwise marginalized communities and is a particular problem for the region’s developing countries.

Propose an innovative approach for:

NOT all deliverables need to be met. Feasible objectives that can be executed should be highlighted and the limitations behind the unmet objectives should be addressed.

Who Can Participate


The winner will collaborate with the World Bank to execute the project and have their analysis included in the World Bank’s EAP Regional Extreme Urban Heat Study by August 2022.
