Most parts of Uganda are currently faced by rapid deforestation. An estimated 120,000 hectares of   trees are cut down every year in Uganda to cover wood charcoal and also for firewood .This has left region bear and very vulnerable to climate change.


Energy Access

The use of firewood and wood charcoal for cooking has the greatest negative effect on women and girls. Women and girls walk long distances every day in search for firewood, keeping girls out of school and preventing women from performing more productive chores.
