Subsistence farmers in Africa, victims of changing weather patterns, are caught in a stormy global debate over a special climate fund for which few want to pay.

Throughout the continent, farming groups are trying to adapt to seasons that are more unpredictable than ever. Frequent droughts or rainy seasons that last too long have decimated crops. Scientists forecast even worse weather in Africa over the next 50 years.

These are some of the problems the United Nations’ Green Climate Fund was supposed to address. On Monday, representatives of the 192 countries plus the European Union, parties to the U.N.’s climate body, gathered in Durban, South Africa, at a U.N.-sponsored climate talk to try—among other things—to elicit $100 billion in pledges.
