Climatic change presents a serious threat to African wildlife and ecosystems in the coming decades.
Among those wildlife reserves likely to be affected are Kruger National Park, the Zambezi basin, and the Okavango delta. In Zambia in 1991, grazing species , such as hartebeest, wildebeest and zebra came under severe stress from droughts. Global warming is already affecting much of southern Africa. Temperatures have risen by over 0.5 C over the past hundred years, with the last decade being the warmest and driest ever. Over the past 20 years, there has been noticeably less rainfall, and wa ter has become much harder to come by for many communities.
