![]() The population comprises several ethnic groups: (1) Amhara, (2) Tigraians, (3) Oromo form an ancient population group in the Raya graben that has been partly assimilated to the surrounding Amhara and Tigraians – the language is not anymore used on a daily basis they live in dispersed villages east of Kobo and on the Zobel mountains, (4) Afar share settlements on the mountains east of Raya. On 10 September 1989: 21 killed, 100 wounded (market day). ![]() In December 2008, construction on a 2.5 kilometer flood wall was completed, which would protect hundreds of hectares of farmland from frequent flooding by the Dikalla river.ĭuring the Ethiopian Civil War, the town of Gobiye in Kobo woreda was bombed repeatedly from the air by the Ethiopian National Defence Forces: A similar program initiated a few years previously led to a decline in the number of farmers migrating to the Afar Region, Djibouti and Sudan. This would use 23.3 million birr of Regional funds to develop basin and degraded mountains, construct all weather roads and irrigation diversion canals, improve springs as well as various "water harvesting structures". The woreda Agriculture and Rural Development Office announced 8 April 2007 that it was starting a program to improve the livelihood of woreda inhabitants, affecting 53,000 farmers. The river passes south of Zobil Mountains. The northern part of Kobo woreda is traversed from west to southeast by Hormat River. To combat increasing droughts and improve crop yields, two irrigation projects have been undertaken in this woreda by the Commission for Sustainable Agriculture and Environmental Rehabilitation in the Amhara Region and the NGO Lutheran World Federation, affecting 302 hectares and benefiting 1,017 households. Kobo, as well as the other seven rural woredas of this Zone, has been grouped amongst the 48 woredas identified as the most drought prone and food insecure in the Amhara Region. In general, the altitude of Kobo ranges from 1100 meters on the plains to slightly more than 3000 meters above sea level along the border with Gidan. The landscape of this woreda is characterized by a broad fertile plain which is separated from the lowlands of the Afar Region by the Zobil mountains, which are over 2000 meters high. Towns in Kobo include Gobiye, Kobo and Robit (Kobo Robit). Located in the northeast corner of the Semien Wollo Zone, Kobo is bordered on the south by the Logiya River which separates it from Habru and Guba Lafto, on the west by Gidan, on the north by Tigray Region, and on the east by the Afar Region. This study also attempts to map malaria risk level of kebeles in the study area, to make malaria control and eradication program of the Woreda time and cost efficient.Kobo or Raya Kobo (Amharic: ራያ ቆቦ) is one of the woredas in the Amhara Region of Ethiopia. In other words, according to the result of the findings large area of the study area (29.41%) is located in very high and high risk area of malaria. The final risk map indicates that from the total of the study area 12.13 % is mapped as very high, 17.28 % as high, 26.71% as moderate, 25.91 % as low and 17.97%as very low malaria risk level. To generate malaria risk map of the woreda, land use land cover map which is the element at risk in the woreda, the vulnerability map and the hazard map were overlaid using weighted overlay analysis technique in ArcGIS. For vulnerability analysis, health station location in Spatial Analyst was used to generate factor maps and land use land cover map was used to generate element at risk map. ![]() To generate malaria hazard map, elevation, slope, temperature, rainfall, soil and distance to streams factors are weighted and then weighted overlay technique was computed. Weights were assigned for these parameters by pair wise comparison method and weighted overlay was used in Arc GIS spatial analyst tools to produce the final malaria risk map of the study area. The analysis was computed using multi criteria evaluation (MCE). The environmental factors considered for the analysis are temperature, rainfall, elevation, slope, soil, land use land cover, distance to streams and distance from health stations. The purpose of this study was to generate malaria risk map of Raya Kobo woreda using GIS & RS techniques. Due to its tropical location and other environmental factors, part of Ethiopia is favorable for mosquito breeding and malaria transmission. Malaria is one of the world’s serious and complex public health problems and it remains one of the greatest killers of human beings in developing countries. ![]()
