Title: Recent resettlement programs, as drivers for Afromontane forest loss in the Hawa-Galan district of Ethiopia Authors: Yadeta, Teferi; Tsegay Deribew, Kiros; Getahun, Kefelegn; Getahun, Kefelegn; Debesa, Gemechu; Abreha, Girmay Abstract: Abstract: Ethiopia has been experiencing resettlement programs primarily as a response to the tragedy of land degradation. The program, however, resulted in massive deforestation in the resettled sites. This study, therefore, aimed at evalu- ating the impact of resettlement on the moist evergreen Afromontane forest cover between 2000 and 2018 in the Hawa-Galan district. Landsat TM of 2000, ETM+ of 2010, and OLI of 2018 were used to detect forest cover change. Likewise, an explanatory sequential approach of mixed research design was used. Hence, 118 participants out of the total 2232 indigenous and resettled households were employed to survey the impact of deforestation.The study area lost 55% of its total area over the last two decades, corresponding to average deforestation rates of 2.06, 6.75, and 4.14% for the corresponding periods: 2000–2010, 2010–2018, and 2000–2018, respectively. Our findings also revealed the demographic, socioeco- nomic, and backgrounds of the resettlers were the prominent triggers. Conversion of forests to other uses will have far-reaching impacts on the residual biodiversity and ecosystem services. Therefore, in the light of resettlement, it is high time for the Ethiopian government to revisit its intervention strategies and resettlement policies in the forest priority areas.

Title: Stochastic modeling of urban growth using the CA- Markov chain and multi-scenario prospects in the tropical humid region of Ethiopia: Mettu Authors: Megersa, Wendiwesen; Tsegay Deribew, Kiros; Abreha, Girmay; Liqa, Tebarek; Badasa Moisa, Mitiku; Hailu, Samuel; Worku, Kenate Abstract: Urban expansion possesses significant negative impacts on the environment, particularly in forest areas worldwide. This study aimed to analyze urban expansion by using stochastic modeling with the CA-Markov chain and multi-scenario prospects in Mettu area, Ethiopia. The Landsat images of 1986, 2000, and 2021 were used. The results reveal built-up areas gained 27.2%, of which cropland and forest accounted for 11.4 and 6.4%, respectively, within the 1986–2021 period. Despite the potential decline in urban growth rates, the model revealed that the spatial extent will likely expand twofold before the 2040s. In the rapid develop- ment (RD) scenario, urban development due to population increase will occur, which is also prevalent in the proposed suit- able urban expansion (PSUE) scenario, but the ecological and eco- nomic protection (EEP) scenario reveals very limited. The findings of this study will have far-reaching impacts on ecological and eco- nomic livelihoods unless green economy principles are effectively implemented.

Title: Spatial modeling of soil loss as a response to land use-land cover change in Didessa sub-basin, the agricultural watershed of Ethiopia Authors: Usman, Kelil; Tsegay Deribew, Kiros; Alemu, Girma; Hailu, Samuel Abstract: Soil erosion is a vector of disturbances to agricultural productivity and economic development in the western highlands of Ethiopia. Yet, tough vegetation cover loss swapped to other land uses could have amplified the soil loss rate at which land cover change preceded, but little is known about their effects on soil loss in the Limu-Seqa watershed. This study was designed to evaluate the historical trends of the effects of land use-land cover change on soil erosion dynamics as a threshold for potential monitoring of soil loss. Satellite image data of 1987, 2002, 2021, and DEM-20 m resolution were used. The RUSLE model was applied with primary parameters to generate soil loss. Findings show that average annual soil loss increased from 4.5 in 1987 to 13.5 t ha− 1 yr− 1 in 2002 and surpassed to 45.35 t ha− 1 yr− 1 in 2021 as a result of LULC changes, particularly the transition of forest and overgrazed land to cropland (43.83%) and dense-forest to poor-open-up forest (6.92%) between 1987 and 2021. Soil loss during the recent study period was substantially affected by a substantial LULC change, from forest to cropland. The severe and very severe erosion risk categories jointly cover more than half of the entire catchment, which con- tributes to two-thirds of the total mean annual soil loss in the watershed, which is found to be over and above soil loss tolerance (SLT) in Ethiopia and tropical regions. Therefore, given the robust economic and political status of priority conservation measures, red hues areas are significant.

Title: POTENTIAL OF NON-TIMNER FOREST PRODUCTS OF THE MAGO NATIONALPARKAS AN IMPLICATION FOR BIODIVERSITY CONSERVATION, LIVELIHOOIMRROVEMENTAND SUSTAIABLE USE OF NATURAL RESOURCES. THE CASE OF MAGO NATIONAL PARK, SOUTH, WEST, ETHIOPIA Authors: Gulilat Kefelegn, Meseret Abstract: 1. Introduction 1.1 Background and justification Forest ecosystems offer ample goods and services; timber and non-timber forest products (NTFPs) being the most common forest products. NTFPs have been studied by researchers from many different academic fields and each field used a slightly different definition of NTFPs. Non timber forest products (NTFPs) are, in broadest sense, any biological resources collected from wild by people for direct consumption or income generation on a small scale (Shackleton and Shackleton, 2004). NTFPs are any products other than timber that is produced in a forest (CIFOR, 2004). NTFPs include different types of food (wild edible mushrooms, fruits, and nuts), medicinal plants, floral greenery, horticultural stock, fiber and dye plants, lichens and fungi, oils, resins and other chemical extracts from plants, firewood and small-diameter wood used for poles, posts and carvings (McLain and Jones, 2005). NTFPs are an indispensable part of the livelihood strategy of communities living in and near forests. Non-timber forest products (NTFPs) constitute an important source of livelihood for millions of people across the world. For centuries, people of the tropical rainforest have been collecting NTFPs either for their subsistence or in exchange for manufactured products and income generation (Pfund and Robinson, 2005). Nevertheless, NTFPs were for long overshadowed by timber products and has received increased policy and research attention only in the last few decades. This policy and research attention was based on three propositions (Arnold and Ruiz-Perez, 2001): The first was that NTFP contribute significantly to the livelihood and welfare for households living in and adjacent to forest. Secondly exploitation of NTFP has ecologically less destructive than timber harvesting and other forest uses, and the third point was that NTFP production and development by giving a foundation for sustainable economic development could reduce tropical deforestation. These propositions encouraged researchers to put much effort on the determination of monetary values of NTFPs as well as their contribution to overall livelihoods. Therefore, recently, there is a growing agreement that NTFPs play an important role in the livelihoods of rural poor as a source of food, medicine, construction materials and income. The interaction between forest and forest dwelling communities has received increasing attention from academicians and policy makers. Owing to the importance of NTFPs from 2 view point of community welfare and sustainable forest management, sustainable management of NTFPs is crucial for sustaining livelihood of rural poor. Ethiopia is one of the tropical countries endowed with rich biodiversity resources that have numerous NTFPs. The rich NTFPs of the country play substantial roles in food security and in poverty alleviation for a large number of communities in the country (Vivero, 2002). For instance, over 80% (approximately 60,000,000) of the population of Ethiopia depend on herbal/wild medicines for their primary health care and biomass-derived fuel for their energy (Demel and Mulugeta, 2005). However, like in other developing countries, the rationales for forest conservation and developments in Ethiopia have been primarily the production of fuelwood and environmental protection. The values and roles of NTFPs in general have been neglected at all times. Indeed, the capacity to promote sustainable NTFPs production and utilization and to facilitate increased financial benefits to local and national users as an incentive for forest conservation has been very low or nonexistent in the country. On the other hand, a closer assessment of the real socio-economic significance of the forest and woodland resources of the country clearly reveals their greater importance with regard to the supply of NTFPs. For instance, Ethiopia’s forest-products-related export materials were mainly NTFPs, such as gums, incense, spices, honey and wax (Mulugeta, 2006). Despite these significances, little information is available on management of the forest resources such as herbaceous plants, shrubs or trees for NTFPs. Only few studies have been conducted on the importance of NTFPs in Ethiopia from the lowlands, from the southwestern moist forest and eastern highlands (Mulugeta et al., 2003; Tadesse and Ararsa, 2004; Tsegaye et al., 2004). In mago national park there is little documented information regarding the diversity NTFPS contribution of NTFPs in particular to the livelihood of the local community and for sustainable natural resources of the park .The local communities the around park is essentially based on agriculture and animal husbandry the feed grass from park used as the, demand for fire wood from the park and also are also beekeepers who own hives in the park.Those area are responsible factors for deforestation park vegetation (tree bush,shrbus) ,loss biodiversity of the park and subsequent consequences such as soil erosion, soil degradation. To avoid or minimize deforestation related negative consequence of the park ,for sustainable use of natural resources and to diversify the livelihoods of rural households, NTFPs can be a right alternative that deserves investigation at the study area. Comprehensive study on the type of NTFPs found in Mago national park, their diversity and their improving 3 the livelihood of the local communities is lacking. Indeed, there is a need to study the NTFP resources and the roles they can play in improving the uses natural resources in sustainable way, which may be used as a strategy for the conservation of the biodiversity of forest park.Therefore, to exploit the multifaceted roles of NTFPs and to ensure NTFPs-based forest management, the diversity and socio-economic significances of the major NTFPs need to be explored. With this rationale, this study is initiated in Mago national park.
