“…As a result, there are large dependencies of farmers on farming. This circumstance is in agreement with studies conducted in other regions [17][18][19][20]. In addition, interviewed government officials and residents responded that high population has led to shortage of land resources and subsequent continuous cropping of farmland.…”

This study assessed current and historic land use, land cover (LULC) dynamics and the level of urbanization in Wolaita Sodo and its peripheries since 1985 up to 2016. Thus, it's aimed to offer an increased understanding of the growing dynamics of land use changes in relation to the level of urbanization. The study primarily employed advanced technologies like GIS and RS to collect and analyze accurate and reliable information. In addition, survey questionnaire was used to gather quantitative and qualitative data from 200 respondents and then linear regression model and descriptive analysis was done by using SPSS v.21 software. The study showed that the area under forestland, bare land, grassland and cropland were declined while the area under built-up area was increased. The spatial coverage of built-up area (Wolaita Sodo) increased from 8.9% in 1985 to 32% in 2016 and increased by 216.8% (8.4ha yr -1 ) between 1985 and 2016. In addition, linear regression analysis also showed that changes in land use were strongly correlated with population growth, except rural settlement. Particularly, the strong positive relationship between urbanization and population growth suggested that demographic and economic factors are the primary drivers of urbanization. The findings of this study possibly indicated that appropriate planning policy should be devised to manage the expansion of the urbanized area so that land is used efficiently as population grows and ensure that urban development also benefits local communities.

“…Values of G p and L p greater than one imply that a given LC has a higher probability of changing to another LC class than persisting in its current condition [67]. If the value of N p were negative, the LC class would have a higher probability of losing area to other LC types than gaining from them [69]. Furthermore, to compute the annual rate of LC changes at different periods, the compound-interest-rate formula proposed by Puyravaud (2003) [70] was used since it provides a standard method for making LC change comparisons that are insensitive to the different periods between observation dates [57].…”

Forests provide multiple ecosystem services ranging from local livelihoods and socio-economic benefits to global ecological services. Despite these benefits, human activities have put immense strain on forest resources, resulting in forest degradation, impoverishment of the environment, and loss of livelihoods. Hence, monitoring forest cover change and identifying its drivers are essential for developing sustainable forest management strategies that restore forest resources and ecosystem services. This study examined the trends of forest cover changes and its drivers in and around the Semien Mountains National Park, Northwest Ethiopia, from 1984 to 2020. Data from Landsat satellite images of 1984, 1996, 2008, and 2020 were used for forest cover mapping and quantifying the changes using remote sensing techniques. A household survey and key informant interviews were also used to identify the drivers of forest cover change. Results showed an overall decline in forest cover and grasslands while cultivated lands, bare lands and built-up areas have registered gains in the study area. The percentage area under forests declined by about 31% (33,084 ha) over the past 36 years. This loss translates to an annual average forest loss of about 1.02% (919 ha). Conversely, cultivated land, bare land, and built-up areas have experienced an increase of about 159% (33,387 ha), 220% (10,121 ha), and 366% (6356 ha), respectively, over the last 36 years. Analysis of the 36-year change detection matrix revealed that about 62% of the study area experienced a transition, of which 21% and 41% were attributable to net change and swap change, respectively. The observed reduction in forest cover was driven by agricultural expansion, population growth, growing demand for fuelwood, livestock pressure, and forest fires. Such drastic changes in forest cover have a detrimental impact on the community’s well-being, biodiversity, climate, and the availability of forest ecosystem services. Thus, the study recommends concerted efforts by stakeholders to develop participatory forest management and public awareness that consider the co-existence of nature conservation and sustainable livelihoods.

Land use/land cover (LULC) changes influence the ecological function, consequence on ecosystem services, which are tightly linked to human wellbeing. However, quantification of the LULC changes and identifying the underlying factors remain patchy particularly in developing nations, despite this information is crucial to propose a feasible restoration action. Therefore, this study investigates the land use/land cover changes and its drivers in central Rift Valley, Ethiopia. GIS and Remote sensors i.e. Landsat 5 (TM), and Landsat 8 (OLI/TIRs) imagery sensors acquired from USGS, and field observation were used. Using the supervised classification method and the support of ArcGIS 10.5 and ERDAS IMAGINE 2014, all images were classified into various land cover types. Focus group discussions, key informant interviews, and structured questionnaire surveys were used to investigate the drivers of LULC change. NDVI was used to detect the vegetation cover change. Woodland, grassland, and barren lands were the major LULC types identified in this study. After 28 years, the woodland cover increased from 20.6% to 40.2% whereas the barren land decreased from 43.4% to 22.6%. Grassland showed very slight increment, i.e. from 35.9% to 36.9%. This implies that area enclosure plays a significant role in the restoration of degraded lands. The highest NDVI values (0.6) were determined in the year 2022 at the end of the classification. Focus group discussants and key informants confirmed that human-induced factors were the major drivers of LULC changes in the study area. Our findings indicated that human interventions are the key determinants of land use/land cover dynamics, and as a result, enforcement of the law and public education campaigns to change human behavior in support of the area enclosure approach are essential to restoring degraded land for the benefit and wellbeing of humans and nature while also advancing the achievement of the global goals.
