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. 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. 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. 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 NGOLutheran World Federation, affecting 302 hectares and benefiting 1,017 households. The northern part of Kobo woreda is traversed from west to southeast by Hormat River. The river passes south of Zobil Mountains. 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. 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". 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. 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.
