ANALYSIS SUMARY: This analysis shows the town of Abyei in South Sudan. The analyzed very high resolution satellite imagery was acquired on the 23rd of January 2011 and compared against two earlier images; from the 19th of December 2010 and the 22nd of June 2008. Returnee areas and
infrastructure development can be identified and are marked with annotations. New buildings and road works are the main changes.

ANALYSIS BACKGROUND: This is a satellite based qualitative analysis map series showing new structures and infrastructure developments in Abyei, Sudan, occurring between 22 June 2008 and 23 January 2011. During this period significant numbers of people returned to the Abyei area from which they were displaced by civil war and its aftermath. According to the UN Office for the Coordination of Humanitarian Affairs 26,270 people had returned to the Abyei area since October 2010. These influxes have resulted in significant development and at the same time have stressed humanitarian relief operations.

Notably, the analysis period follows a brief but intense episode of conflict occurring in May, 2008. At that time, soldiers of the Sudanese Army and the Sudan People's Liberation Movement, and militias allied with both sides, caused significant destruction to the town following intense fighting. Up to 90% of the housing was destroyed at that time and many shops and facilities looted, according to sources quoted by the UN High Commissioner for Refugees. Analysis of Abyei by UNOSAT using a pre-conflict imagery indicates a strong recovery from this violence as well as significant expansion from its pre-conflict size.

Infrastructure Changes
Abyei saw significant development to infrastructure within the time period from 22 June 2008 and 23 January 2011 as the town increased in size, facilities expanded, roads multiplied in number and were often paved, and water availability was enhanced. A rapid UNOSAT mapping exercise documented almost 2 millions square metres of significant development within 21 areas of new buildings and expanded compounds, more than 32 kilometres of new roads including 17 new or significantly expanded unpaved roads as well as 5 newly paved road segments, 15 water reservoirs, and one new water canal.
