Decadal Impacts of Climate Change on Rainfed Agriculture Community in Western Somaliland, Africa

The western region of Somaliland is prone to climate change and variability due to the widespread use of rainfed agriculture, which has been the practice historically since the colonization era; however, this mode of livelihood is losing its significance due to climate change. This research aims to examine the impact of climate elements’ trends (rainfall and temperature) on rainfed agriculture communities and how these changes affect the rainfed agriculture community. The specific objectives of this study are to determine the major trends of precipitation and temperature over the past three decades, and to assess the level of awareness of climate change in communities’ perception of environmental change in terms of rainfed agriculture. Hence, the study adopted a mixed-methodology approach to concluding the quantitative and qualitative aspects of the research. The main outcome of this study was that climate change has been an active challenge in western rainfed agriculture regions of Somaliland for the last three decades. Decadal precipitation and temperature trend analysis (1985–2015) indicated reduced rainfall both annual and seasonal, and an increase in annual temperature, both in terms of the maximum and minimum. The decrease in annual total rainfall from the Awdal and Waqooyi Galbeed regions was 2 mm/year and 1.5 mm/year, respectively, while in the long rainy season, the decrease of rainfall was 1.4 mm per season and 0.88 mm per season, respectively. In the case of maximum and minimum annual temperatures, both stations depict an increase in temperature. This increase in temperature was 0.043–0.045 °C for the Awdal region and 0.06–0.02 °C for the Waqooyi Galbeed. The qualitative phase of this study supported the quantitative observations, and respondents (≥45 years of age) reported decreasing annual rainfall, a declining long rainy season, and increasing maximum and minimum temperatures. Furthermore, participants mentioned an increase in the occurrence of drought, a reduction of rainfed agriculture productivity, the disappearance of indigenous plants and animals, and an increase of exotic plant species. In addition to that, respondents outlined current adaptation practices; however, these adaptation strategies are short-term, and farmers need more appropriate and practical adaptation practices in the future.
