The rainmakers in Nassapir village, in northeastern Uganda's semi-arid and under-developed Karamoja region are convinced the rain god is angry.

"We don't know why the god is no longer answering our requests," said Laurien Lokwareng, an elder of the Jie ethnic group. "For years, we used to ask the god for rain and we got it in abundance, but we have had four years without enough rain now, and this is very strange."

In a new report, global aid agency Oxfam says impoverished communities like Nassapir are already being hit hard by the effects of global warming, including increased drought.

Without international funding to help them cope and tough targets for cuts in greenhouse gas emissions, the food, water, health and livelihoods of hundreds of millions of the world's poorest people will be put at even greater risk.

Oxfam says interviews it carried out with farmers in 15 countries in Africa, Asia and Latin America show that seasons are shrinking in number and variety.

Rainfall is reported to be more erratic, shorter and more violent. Unusual weather events -- including storms, drier spells and fluctuating temperatures -- are happening more often. And farmers say winds and storms have got stronger.

Increased hunger

Savio Carvalho, Oxfam's climate change adviser for the developing world, told Reuters global warming was already affecting people across Africa, and would wipe out efforts to tackle poverty without urgent action like massive tree planting.

"In sub-Saharan Africa, (yields of) maize, which is a staple crop, will decrease by 15 percent by 2020 and that is a big number," he said.

"Drought is now happening on a yearly basis, and there is increased hunger and starvation because of declining food stocks, as we see here in Karamoja," added Carvalho.

Uganda's Health Ministry says the malnutrition rate in the region -- which has experienced 14 droughts in 25 years -- is 19 percent. The U.N. World Food Programme provides food aid to at least 970,000 of Karamoja's 1.1 million people.

Oxfam also warns that in places like Karamoja - already plagued by high levels of violence due to armed cattle raids between ethnic groups - failure to improve access to water is likely to exacerbate conflict.

The report says the worst effects of climate change on hunger and poverty can be avoided if communities and governments start adapting now.

The agency is taking practical steps, building a dam in Nassapir to capture any rain that does fall for people and animals.

Oxfam's Carvalho also recommended developing drought-tolerant maize seeds, and experimenting with alternative sources of energy in poor rural areas, where most people rely on cutting down trees for firewood and construction.

He said there were several possibilities in Kotido, the district that includes Nassapir.
"Poverty is compounded when people don't have access to energy, and people in places like Kotido could start exploring bio-gas from cow dung and solar energy from the abundant sunshine, with a bit of investment," Carvalho said.
