New research has found that smallholder farmers in Malawi can grow bigger maize crops if they plant maize with legumes in deep beds with natural ditches to catch water alongside.
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.
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?
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.
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.
