Extreme weather events -ranging from flash floods, droughts, to extreme temperatures and dust storms- have had tangible impacts on Khartoum.
Ideas should be focused on finding solutions to these pressing areas:
• Energy Supply and Consumption • Water Infrastructure • Efficient Use of Public and Private Spaces High Temperatures
Amongst the various climatic factors which may affect energy consumption, temperature is the most dominant one in Khartoum. Increases in temperature will increase our energy demand to run cooling devices in the summer. Extreme heat poses a threat to the livability and sustainability of cities, and disproportionally harms marginalized groups. The frequency of extreme heat events is expected to increase in the future as climate change exacerbates urban heat island (UHI) effects. Targeted solutions: energy conservation solutions, innovative methods to increase the reliance on renewable sources of energy and microclimate mitigation strategies (i.e. eco-friendly cooling systems) that could reduce the impacts of climate change and extreme weather on the energy system.
Heavy Rains and Flash Floods
Flash floods caused by heavy rains have always been a serious weather event that have extremely affected many parts of Sudan, including Khartoum and other neighboring areas (1988 and 2013 floods). The adverse impact of droughts and floods in Sudan, threatens sustainable livelihoods. Khartoum is vulnerable to flash floods because of poor drainage and urban planning. The 2013 floods were particularly severe where more than 15,000 homes in Khartoum were reported to have been destroyed, with thousands more damaged. Targeted solutions pertaining to sustainable urbanism with special focus on drainage systems, flood resilient construction and adaptation of buildings, strengthening climate information and early warning systems, and efficient water harvesting techniques to capture excess water.

Desertification and Dust Storms
Khartoum city underwent a considerable population growth during the last decades, as a result, a part of the green belt South of Khartoum has been chopped down and converted into residential areas. Green Belt before its removal offered protection of the population from wind blowing dust, providing shades, decreasing the rise of temperature through the evapotranspiration of trees, conserving the soil removal from erosion by wind and rainy water. Targeted solutions: efficient use of public and private spaces to increase green spaces, and sustainable land management ‐ Integrated landscape management ‐ Integrated water management.
