Forest cover in East Africa has dropped by 9.3 percent from 2001-2009, according to a new paper published in the open-access journal PLoS ONE. Looking at 12 countries in the region, the scientists found that, worryingly, forests were particularly hard hit near protected areas. Usually thought of as a region of vast savannas, such as the Serengeti, East Africa is also home to incredibly biodiverse tropical forests, including coastal forests, rich montane forests, and the eastern portion of the Congo Rainforest.

"Large areas of evergreen forests have been lost from East Africa during the 20th century resulting in carbon emissions, reduced habitat for forest dependent biodiversity, and reduced availability of essential ecosystem services," the researchers write. "Initial conservation efforts in East Africa, like elsewhere, focused on creating protected areas."


However, the study finds that protected areas do not always live up to conservation goals. According to the study, 46 percent of East Africa's National Parks lost forest cover in the last decades. Worse still, 50 percent of Nature Reserves (losing a cumulative 5.3 percent of forest cover), 61 percent of Forest Reserves (-3.5 percent), and 92 percent of Game Parks (-24.4 percent) lost forests. Just outside of protected areas, forests were particularly vulnerable, with buffer zones losing forest at an even faster clip.

The study also found some evidence for leakage — that protecting forests in parks simply lead to increased deforestation outside protected boundaries — but cautions that more research is needed.

Booming populations and the ease of accessing a particular were the two main drivers for deforestation in the region, according to the study. Local people clear forests for agriculture, grazing land, and for charcoal to burn. Roads are bringing more people to the edges of protected areas, where, in some cases, forest loss was more severe than national rates. Commercial logging, both legal and illegal, is also taking a toll.

The best way to mitigate deforestation in the region is not to keep locals out however, says the study. In fact, current data "suggests that involving local communities in forest management improves forest conservation outcomes," the scientists write. They point to Kenya's Mukogodo Forest Reserve and Tanzania's Vumari Forest Reserve as innovative conservation areas that allow community participation and resource collection, and note that Tanzania's Participatory Forest Management (PFM) program is a model worth emulating.

"[PFM] increases decision-making powers of villages on the use of forest resources and empowers them to declare, own and manage their forests," the authors write.

Deforestation was most severe in Rwanda and Uganda, but South Sudan actually saw forest cover increase during the time period in question.

Ten African nations pledge to transform their economies to take nature into account

(06/11/2012) Last month ten African nations, led by Botswana, pledged to incorporate "natural capital" into their economies. Natural capital, which seeks to measure the economic worth of the services provided by ecosystems and biodiversity—for example pollination, clean water, and carbon—is a nascent, but growing, method to curtail environmental damage and ensure more sustainable development. Dubbed the Gaborone Declaration, the pledge was signed by Botswana, Liberia, Namibia, Mozambique, Rwanda, Gabon, Ghana, Kenya, South Africa, and Tanzania following a two day summit.

The government of Tanzania has proposed a controversial highway that would bifurcate the northern part of the Serengeti National, only to see their plans stalled by a lawsuit filed by the Kenyan-based NGO, Africa Network for Animal Welfare (ANAW), which argues that the road could have massive consequences for the entire Serengeti ecosystem, a view shared by many scientists.


Africa Wildlife Foundation faces lawsuit from indigenous community in Kenya

The hearing, originally scheduled for January 23, has now been postponed to later this month. The dispute is over an area of land in Laikipia District in Kenya, one of Africa’s most wildlife rich areas. Until recently, it was also the homeland of some 2,000 semi nomadic members of the Samburu tribe. At least according to the Samburu.
