There are a number of refugee camps located in Gambela region housing around 268,000 refugees from South Sudan in August 2016: From August 2016 to August 2018, the numbers increased from 268,000 to 402,000 refugees, almost equaling the native population of Gambela Region. Economy The CSA reported that for 2004-2005 3,734 tons of coffee were produced in Gambela, based on inspection records from the Ethiopian Coffee and Tea authority. This represents 1.64% of the total production in Ethiopia. The CSA could not provide livestock estimates for Gambela. In a 26 May 2000 report, the FAO observed that at the time Trypanosomiasis was a major problem in cattle for this region. There was an epidemic of this disease in the area during 1970. Gambela is believed to have major oil resources. In June 2003, the Ethiopian government signed an agreement with Petronas of Malaysia for the joint exploration and development of oil resources in Gambella region. Petronas then awarded a contract for seismic data acquisition to China’s Zhongyuan Petroleum Exploration Bureau (ZPEB) October of that year. The Water and Mines Resources Development Bureau of Gambela announced January 2007 that it was initiating a program that would drill 13 new manually operated wells, 54 new deep water wells, and develop four springs. This would provide access to drinking water for 26,000 inhabitants, increasing coverage for the state to 42 percent from the existing 27 percent, at a cost of 6 million Birr. Construction of an asphalt road 102 kilometers in length and connecting Gambela City with Jikawo by way of Itang was begun in 2008 with a budget over 446 million Birr. As of 2015, Indian investors have acquired 6,000 square km of land in the Gambela region, following other investors, for agricultural land from the central government. This has led to conflict with regional government officials and local communities. Not all the land is actually being farmed, as per the agreement, and there are accusations of investors illegally clearing trees in the Gambella National Park in a blog. Administrative subdivisions While Gambela is subdivided into administrative zones and woredas as other regions in Ethiopia are, this region has seen the most changes in these subdivisions of any region, to the point they can confuse anyone tracing their development. Originally, Gambela was subdivided into four administrative zones without proper names (1, 2, 3 and 4) and one special woreda (Godere special woreda).
