As if Africa doesn’t already have enough problems, now climate change is destroying African farm land!
A new study by researchers from the Nairobi-based International Livestock Research Institute (ILRI) and the United Kingdom’s Waen Associates has found that by 2050, hotter conditions, coupled with shifting rainfall patterns, could make anywhere from 500,000 to one million square kilometers of marginal African farmland no longer able to support even a subsistence level of food crops. …
The researchers then considered the impact of climate change in these regions and found that even in situations where climate change is moderated somewhat by global reductions in carbon emissions, a large number of farmers most likely will still face a considerable deterioration in growing conditions. The key measure was whether climate change under two widely used climate models—which offer projections based on high and low greenhouse-gas emission scenarios—would cause the number of “reliable crop growing days” to drop below 90 days between 2000 and 2050.
They concluded that under scenarios in which carbon emissions remain high, the number of reliable growing days would drop below 90 for almost one million square kilometers of marginal growing lands in Africa. Assuming a “lower emission scenario,” they project about 500,000 square kilometers would fail to reach the 90-day mark.
This study is just more evidence that the governments of the world aren’t going to be able to solve this problem on their own. The problem of climate change belongs to all of us, and we’ve each got to make a contribution to the solution. One of the easiest first steps you can take is to buy carbon credits to offset your personal carbon use. Carbon offsets also make great gifts for your earth-conscious friends, or even skeptics!
