The remote Bassari community, located between Senegal and Guinea, experiences climate change as one of many changes. They are best placed to come up with solutions that work for them.
Only 5% of South Africa’s energy comes from solar power while 85% is generated from coal. Loans, more subsidies and security for rooftop solar panels need to be put in place.
As renewable energy becomes cheaper and climate change affects water availability, the contribution of hydropower will decline.
The carbon stored by forests can be bought by polluting companies to offset their emissions. This can displace communities who depend on natural forests for their livelihoods.
Kenya, Ethiopia, Djibouti, South Sudan and Uganda are investigating whether deep groundwater bores could support drought stricken communities. Could a networked approach help?
Sweet sorghum has multipurpose post-harvest uses. It can produce grains, animal feed and sugary juice, making it unique among crops.
Baby corals may hold promise for building coral reef resilience in Seychelles and beyond.
In Madagascar, communities and scientists are growing tens of thousands of baobab seedlings to restore the 1,000-year-old forests.
Business and management graduates can become the kind of sustainability champions the world needs today.
Planting millions of trees in natural grassland is largely ineffective in the battle against global warming because it adds little or no additional carbon storage.
A growing number of people are opting to generate their own renewable energy and escape load shedding.
Wetlands can prevent flooding, trap carbon and support livelihoods, as long as they are protected and managed.
Just three plant species – wheat, maize and rice – account for 60% of all food eaten globally. A crop science expert argues that many of Africa’s 30,000 edible plants must be revived.
Garbage is decomposing in landfill sites across sub-Saharan Africa, releasing methane gas. If governments harnessed this as clean energy, Africa would avoid environmental damage worth US$6.7 billion.
Some geoengineering techniques are better understood than others. The US is investing in capturing carbon dioxide from the air, but ideas to block the Sun’s rays are raising big concerns.
Climate change board games can help players grasp the issues by experiencing them first-hand.
Climate innovation prizes only make up a small amount of climate research funding but are very high-profile events.
Two experts in policy and technology who were also co-authors of an international climate assessment see reasons for optimism.
Climate change and its solutions are complex. One way to understand them — and the decisions that come with them — is through “systemic storytelling.”
