Land use and land cover (LULC) changes have severely threatened ecological and economic sustainability in highland Ethiopia. A clear insight into its extent and rate is, therefore, a crucial step for effective land use planning and decision making. The main objective of this study was to analyse the nature of LULC change and its impacts in north‐western highland Ethiopia over the last four decades, using the integrated approach of remote sensing and geographic information system in combination with field data. Multidate Landsat images were used for spatio‐temporal change detection through the help of ArcGIS 10.3 and ERDAS IMAGINE 2014 software. A pixel‐based statistical analysis was used to measure class‐to‐class changes and total losses and gains of each LULC class during the study period. The results show that a significant and widespread change of LULC has occurred in the study area during the period 1973–2016. The cropland, grassland, and shrubland were the dominant LULC types taking more than 95% in total over the entire study period. The cropland and built‐up land showed a significant increase from 1973 to 2016, whereas grassland and shrubland decreased gradually over the same time period. The LULC change in the study area has caused severe environmental degradation, which in turn has affected ecological sustainability, agricultural productivity, food security, and rural livelihoods. The results of this study are expected to provide local‐level current information on the extent, rate, and impacts of LULC change for decision makers seeking to ensure ecological, social, and economic sustainability.

“…In the past few decades, rapid population growth and rising demand for food in Ethiopia have led to a considerable expansion of cropland at the expense of forest, shrubland/woodlands and grasslands in various part of the country [25][26][27][28][29][30][31]. More than 23 million ha of forest and shrubland/woodlands were cleared since the second half of the twentieth century to make way for agricultural production in the country [32].…”

This study evaluated the effect of Land Use and Land Cover (LULC) dynamics on the value of ecosystem services in Abaya-Chamo basin over 1985-2050. The main objectives of the study were to estimate the value of ecosystem services of Abaya-Chamo basin using local and global ecosystem service value coefficients, assess how it changes over time, and develop tools to inform policy and public decision-making to protect lands and waters in the region. The study utilized observed (1985 and 2010) and predicted (2030 and 2050) LULC datasets and ecosystem service value coefficients obtained from publications in peer-reviewed scientific journals. The results indicated that the total ecosystem service value of Abaya-Chamo basin was 12.13 billion USD in 1985 and 12.45 billion USD in 2010. The value is predicted to increase to 12.47 billion USD by the year 2050, which is 2.84% (344.5 million USD) higher than the total value of ecosystem services of the basin in 1985. Although the total ecosystem service value of the basin showed a slight increase over the study period, it was observed that the total value of services obtained from natural ecosystems is expected to decline by 36.24% between 1985 and 2050. The losses of services obtained from natural ecosystems, such as water regulation and erosion control, are major concern as the consequence has already been reported in the basin in the form of reduced water quality and productivity of the lakes due to an increased soil erosion and sediment transport in the basin. Therefore, special attention should be given to the rehabilitation of degraded ecosystems and the protection of remaining natural vegetation and water bodies to enhance natural capital and ecosystem services in the basin. A large-scale dissemination of eco-agricultural land use practices, which provide multiple ecosystem services (such as agroforestry and heterogeneous agricultural areas) in the basin, needs to be considered in the future.

“…For example, Ariti et al and Garedew et al [9,15] reported the expansion of cropland at the expense of forest, woodlands, grasslands, and water in the Central Rift Valley. Similarly, Gashaw et al [16] reported a reduction of forest, shrubland, and grassland between 1985 and 2015 in Andassa watershed in the Blue Nile Basin as a result of the expansion of cultivated land in the area. Increases in cultivated land at the expense of pastureland, forestland, and woodland were also observed in hilly-mountainous areas in the central highlands [14].…”

This study uses a combination of remote sensing data, field interviews and observations, and landscape indices to examine the dynamics of land use and land cover (LULC), identify their driving forces, and analyze their effects on the landscape of Abaya-Chamo Basin (ACB) between 1985, 1995, and 2010. The results reveal that the landscape of ACB has changed considerably during the past 25 years between 1985 and 2010. The main changes observed imply a rapid reduction in shrubland (28.82%) and natural grassland (33.13%), and an increase in arable land (59.15%). The basin has become more fragmented and formed less connected patches in 2010 compared to 1985. Rapid population growth, internal migration, policy shifts, and regime change were identified as the key driving forces of LULC changes in ACB. The LULC changes and related trend of increasing landscape fragmentation in the basin increased soil erosion, the volume of surface runoff, and sediment transport in the landscape and, consequently, affected the levels and water quality of the lakes found in the rift floor. Furthermore, the destruction and fragmentation of shrubland and natural grassland led to the decline of wild plants and animals previously prominent in the basin. Therefore, protective measures that take into consideration the economic, social, and ecological dynamics of the basin are urgently needed to save the aquatic and terrestrial ecosystems of the basin from further damage.
