It's mainly industrial nations that are responsible for producing greenhouse gases such as CO2 that contribute to climate change. But the main victims of climate change are in the countries of the global South. As Africa is hit by drought, storms, erosion and desertification, people there are starting initiatives to combat climate change.

Mozambique is the African country most affected by extreme weather events. Entire neighborhoods in the coastal town of Beira are already endangered by rising sea levels and flooding from heavy rain. Experts say weather related disasters force twice as many people from their homes than conflict and violence. It's estimated Africa will experience some 20 million climate refugees within ten years.

The world's leading climate change advisory body, the IPCC, estimates sea levels will rise by 40 to 80 cm by 2100. To improve water drainage, Beira is rehabilitating the river which flows through its center, carrying out reforestation and constructing a new canal. It is also building a barrier which can be closed at high tide to protect the town.

The yellow sands of the Sahara desert continue to creep their way south, encroaching on the farmlands of sub-Saharan Africa. Eleven African countries are trying to stop this drift with a 7,750 kilometer long and 15 kilometer wall of trees. Tree roots stabilize and aerate the soil, allowing the absorption of water and stopping desertification. It will also provide people with new livelihoods.

Soil erosion and desertification threatens the livelihood of farmers in many parts of Africa. Using a special irrigation system, Sounna Moussa from Niger is making his soil fertile again. His technique is centuries old but had been virtually forgotten. Experts also recommend growing traditional crops better suited to the soil.

Hydropower is the world's largest source of renewable energy. Traditionally, it is seen as a reliable and clean way of generating power. But now hydropower is meeting more resistance from environmental groups and local communities. Sometimes whole forests are cut down or villages are relocated to make way for a new hydroelectric dam.

All of Africa will have access to power by 2030. This ambitious goal was set by 55 African heads of state and government at the 2015 Climate Change Conference in Paris. The Africa Renewable Energy Initiative plans to feed 300 gigawatts of green electricity per year into power grids across Africa. Wind farms like this one here in Ethiopia are just the beginning.

People across Africa are increasingly generating their own green electricity rather than relying on dirty generators or unreliable grid power. Dramatic drops in the price of solar power now make renewable electricity more affordable, whether it's powering a hospital or school with a row of solar panels or lighting a home with a small solar lamp.

In Africa, the upcycling trend hasn't just conquered the fashion world but also the construction industry. In Nigeria, people are building whole houses from used plastic bottles that otherwise litter the environment. It's estimated that a million plastic bottles are bought every minute around the world.

Getrude Clement is committed to protecting the environment. Once a week, the Tanzanian teenager produces an environmental program for her local radio station. "I hope my listeners are doing something to change the situation here - to protect the environment and keep our water clean," she told DW. She's seen here speaking to the UN General Assembly in New York in April, 2016.

To make Africa more resistant to climate change, its effects need to be better understood at local and regional levels. The southern African scientific organization SASSCAL is working on this, with support from Germany. SASSCAL aims to lessen the impact of climate change on agriculture and water.

Hurricane Irma has killed dozens of people and injured many more since the record-breaking storm roared over the French Caribbean islands. With its powerful winds having topped 185 miles (295 kilometers) per hour, Irma is the strongest storm ever recorded in the Atlantic Ocean, according to the US National Hurricane Center based in Miami.

The Franco-Dutch island of Saint Martin suffered the full fury of the storm. Rescuers on the French side said at least eight people died and some 95 percent of homes were destroyed. The Netherlands and France both sent troops and medics to help with rescue efforts.

Prime Minister Gaston Browne said Barbuda was a "scene of total carnage." Officials on the tiny two-island nation said it will seek international assistance. He further reported that about half of Barbuda's 1,800 population were homeless while nine out of 10 buildings had suffered damage, many of them destroyed.

Puerto Rico Governor Ricardo Rossello said about two-thirds of the island's 3.4 million inhabitants lost electricity in the storm. Shelters have been set up for about 62,000 people whose homes were destroyed.

Irma crawled across Cuba's northern coast, bearing down on the island nation as a Category 5 hurricane. It left thousands of homes, businesses and hotels flooded. The hurricane's storm surge topped Malecon, the iconic seaside boulevard in the capital of Havana. Cuba is often hit by hurricanes that strike the Caribbean.

Irma made US landfall in Key West, then again on Marcos Island on the US state of Florida's Gulf Coast. The storm brought several tornadoes, which leveled homes in the eastern city of Palm Bay. In Miami, hurricane-force winds brought down two cranes. State authorities have vowed a swift response to aid victims of the hurricane and cleanup its devastation.

Although Georgia and South Carolina avoided the worst of Irma's destructive path, Georgia Governor Nathan Deal declared a state of emergency after 340,000 were left without electricity and four people died. Atlanta's Hartsfield-Jackson International Airport, one the world's busiest airports, was forced to cancel some 800 flights on Monday.

The destructive storm also left other victims in its wake, namely marine wildlife. The hurricane caused water levels to rise and fall much quicker than normal, leaving some animals, like this manatee, behind to die on land.

Irma follows hot on the heels of Hurricane Harvey which devastated large swathes of Texas and Louisiana in late August. Before Irma made landfall in the US, two other storms, Jose in the Atlantic Ocean and Katia in the Gulf of Mexico, were upgraded to hurricane status. Weather forecasters believe Jose could still pose a threat to the continental US.
