Abstract: This study was conducted in Awash National Park, Ethiopia, to analyse woody species composition and estimate carbon stock potential of woody species in different vegetation types. A total of 80 quadrats of 20m x 20 m, 5m x 5m and 1m x 1m with 16 horizontal transect lines were used to collect information on tree, shrub, and litters and soil respectively in the four vegetation types. A total of 52 woody species belonging into 23 families with stem number of 1369 individual/ha were re...
Abstract: Urban vegetation stands as a pivotal ecosystem for the provision and support of ecosystem services in towns and cities leading to the attainment of SDG 11: “Make cities and human settlements inclusive, safe, resilient and sustainable.” In pursuit of this goal, this study aimed at determining the present urban tree species richness, diversity and carbon stock potential in Lilongwe City, Malawi. Six distinct urban forest types were identified: Cemeteries, Institutional lands, Par...
Abstract: Land degradation and climate change is the global challenge, where their impact is profoundly seen in developing countries including our country (Woolf et al., 2018). The Ethiopian Productive Safety Net Program (PSNP) is one of the national climate smart initiatives (CSI) implemented to address the persistent land degradation and climate challenges in the country. However, the PSNP effect on Land Use Land Cover (LULC) changes and its carbon storage potential is not yet studied at l...
Abstract: Previous vegetation studies and their ecosystem services have concentrated largely on natural ecosystems, with less emphasis on managed areas like agricultural systems. Moreover, the protection and conservation of vegetation would be not only successful in protected areas alone but also in the agriculture environment and surrounding it. More recently, human-altered ecosystems such as conventional agroforestry like agri-silviculture have become increasingly conscious of their abilit...
Abstract: Common bean is an essential crop for food security, nutrition, and country economy mainly for Sub-Saharan African’s smallholder farmers. However, the production and productivity of common bean is mainly constrained by post-harvest loss induced by Mexican bean beetle. Thus, the objectives of this study were to evaluate the effectiveness of Plant seed powders (neem, Hochst and wild marigold), leaf powders (sweet fennel and broad-leaved croton), plant essential oils (neem and Hochst...
Abstract: Understanding the influence rainfall variability on agricultural production is needed to cope with current and future changes in rainfall variables especially in countries that largely rely on rain fed agriculture. The objective of this study was to analysis rainfall variability, farmers’ perception and adaptation strategies in the Daro Lebu Woreda. To achieve this objective, historical climate data from 1995-2019 were obtained from Ethiopian National Metrological Agency. In addi...
Abstract: The aim of this study was to assess the dynamics of land-use-land-cover change and its effect on the rangeland ecosystem services of Shinile district. Landsat images of 1999, 2009, 2019 were downloaded from USGS earth explorer with a spatial resolution of 30 m and preprocessed and classified by using ERDAS imagine software to identify land cover types. The ground control points were collected from the field to assist the land use-land cover classification. In addition, a key inform...
Abstract: The issues of a social network, pluralism in the seed system, and adaptation to climate change are becoming more commanding in the tragedy of climate change and variability. Adaptation decisions are often based on interactions between people and their collective activities, which are mediated through informal networks from which resources may be derived and facilitate access to information needed for adaptation. The objective of this study was to analyze the role of social networks...
Abstract: A study was conducted in Dikicha Kebele, Miyo District, Borana Zone of Southern Ethiopia, to compare woody species diversity, uses, and regeneration status, and soil organic carbon of conserved and non -conserved adjacent sub-watersheds. In each sub-watersheds, four transect lines were systematically laid parallel to each other at 200 m interval. Ten nested sample plots were established at interval of 50m along each transect lines. The main plots had 30m X 30m while sub-plots had 5...
Abstract: Evaluating the effect of land uses on the soil physicochemical properties and organic carbon stock under different land use types are crucial option for sustainable soil and land management, and fighting climate change by improving soil health and quality. In the Liben District of southern Ethiopia, a study was carried out to investigate the spatial variability of selected soil physicochemical properties and organic carbon stock under different land use types. In total, 81 undistur...
Abstract: Soil salinity problem is predominantly severe in developing countries, particularly in arid and semiarid regions, resulting in short-term damage to people's livelihoods and long-term repercussions on the country's food security. It is also a major challenge in Ethiopia and west Hararghe in particular where small-scale irrigated agriculture is practiced. Against this backdrop, this study was conducted to assess the soil salinity and irrigation water quality in dry season wheat produ...
Abstract: In Ethiopia agriculture is highly vulnerable to climate variability. This is mainly due to its mere dependence on rainfall and low level of technology adoption. Thus, the aim of this study was to investigate farmers’ resilience to climate variability and their perception towards adoption of climate smart agricultural practices in the study area. A multistage sampling technique was employed to select sample households. Accordingly, 204 sample households were selected using simple ...
Abstract: Solid waste management is critical issue faced by urban areas worldwide. The rapid increases of population size, urbanization and industrialization resulted in increased generation of solid wastes. Consequently, solid wastes and its management became major public health, environmental and socio-economic concern.This study aimed to investigatethe solid waste management system and associated risk factor of the environment, public health and socio economic aspects;in the case of Adama...
Abstract: The dry Afromonatane natural forests of East and West Hararghe are under severe degradation. There are some remnant mountain forests in West Hararghe, which are under increasing anthropogenic threats and call up urgent conservation actions. This study was conducted at Hades dry Afromontane natural forest, West Hararghe zone of Oromia Regional state, Ethiopia with the objective of determining the woody species composition along altitudinal gradients and conservation status. The data...
Abstract: Continuous conversion of land for different agricultural production purpose has resulted in degradation of soil resources. The decline of soil fertility and soil organic carbon stock become notable phenomena in the highlands of Ethiopia. The present study was conducted to analyse and quantify the land use/land cover changes over the periods of 28 years and to investigate the influence of A. decurrens tree-based farming system on selected soil properties and soil organic carbon stoc...
