Abstract: Gold mining brings several benefits to developing countries like Ethiopia, which could be manifested mainly as employment opportunity and income generation but simultaneously there has been high negative impact on the environment especially on the biodiversity. This study was conducted to investigate the impacts of the ongoing traditional gold mining (TGM) on the natural vegetation in the Kafta-Shiraro National Park (KSNP). A comparative vegetation analysis was conducted between th...
Abstract: Solid waste, which is a consequence of day-to-day activity of human kind, needs to be managed properly. The improper management of the MSW is a major cause for water, air and soil pollution. Municipal solid wastes (MSW) generations and characterization of its composition is essential for proper management of municipal solid waste in the study area. This study aims to determine generation rate and physico-chemical characterization of Municipal Solid Waste in Fonko Town. In present s...
Abstract: Throwing unsorted and untreated municipal solid waste on streets is a threat to human health and environment in rapidly growing towns. Determining the generation rates and characterization of physicochemical properties is essential to figure out the adverse effects solid waste in the environment. The purpose of this study was to characterize physicochemical properties of municipal solid waste and determination of its generation rate at Jajura Town. In order to achieve this objectiv...
Abstract: Investigating the dynamics of meteorological variables in the context of changing climate, particularly in countries where rainfed agriculture is predominant, vital to assess climateinduced changes and suggest feasible adaptation strategies. To that end, this study was conducted in Gibe Woreda of Hadiya Zone, Southern Ethiopia to analyze rainfall and temperature variability impacts on Wheat (Triticum aestivum L.) productivity and adaptation strategies among smallholder farmers. Dat...
Abstract: P. juliflora is an evergreen exotic poisonous weed species and its alarming rate of invasiveness had affecting the livelihood of pastoral communities in Amibara rangeland of Afar Region. This study aims to investigate effects of P. juliflora on soil seedbank flora and its allelopathic potential on seed germination, growth and biomass production of Cenchrus cillaris, paspalidium desertorum and Litonia nutans. A total of 20 Soil samples were collected from five sites measuring sample...
Abstract: Deforestation has significant negative impacts on the livelihood of the local community. The rate and extent of deforestation is much higher today than in the past. However, the impact of deforestation on community livelihood is not documented. Therefore, this study was aimed to address and fill the existing theoretical and practical research gap. That means by providing the necessary information about the impact of deforestation on rural livelihood. This research was carried out w...
Abstract: Water scarcity is a critical issue for many developing countries in general and for those in the arid to semi-arid areas of the world in particular. It is a key challenge and a major constraint to economic and human development in the ASA areas of Ethiopia. To mitigate the threat from water scarcity, there have been extensive efforts and attention given towards rainwaterharvesting technologies because of its potential as a viable option to address the problem. This study focuses on...
Abstract: Watershed management practice was taken as the basic operational unit to rehabilitate the degraded land and improve agricultural productivity of land in Ethiopia. However, its impacts in rehabilitation of degraded land were rarely evaluated. This study was designed to assessed the impact of watershed management practices on woody plant composition, farmers’ perception and identify the factors that affect the adoption of soil and water conservation practices based on comparative a...
Net Surface Shortwave Radiation (NSSR) is a key quantity for the estimation of net radiation (𝑅𝑛) and 𝑅𝑛 is a key component of the Earth energy balance. The most practical and reliable method for estimating solar radiation is based on remote sensing because remote sensing observation values are practical than location based measurements. It has been observed that existing ancillary data are not sufficient to have an accurate solar radiation estimates due to the limited amount of g...
Ecosystem services are the beneficial outcomes, for the natural environment or people that result from ecosystem functions. Some examples of ecosystem services are support of the food chain, harvesting of animals or plants, and the provision of clean water or scenic views. In order for an ecosystem to provide services to humans, some interaction with, or at least some appreciation by humans is required. Thus, functions of ecosystems are value-neutral, while their services have value to...
ABSTRACT Rapid growth of businesses and population in and around Arua town has led to increased production of solid waste consequently giving rise to increased volume of waste dumped in recipient communities. The most attractive and environmentally friendly option to get rid of this huge pileup of garbage and subsequent ones is through composting. The perceptions of recipient communities are crucial to understanding how municipal solid waste management problems might be resolved. Since Arua...
ABSTRACT The study in Gishwati forest Reserve aimed at determining the effect of anthropogenic activities on tree species diversity. Three areas within the forest were described as Disturbed Forest (DF), Natural forest (NF) and secondary forest (SF) in consideration of level of human disturbance. Data collection was done using plot sampling based on enumerating tree species (with a diameter at breast height ≥10 cm) within the forest, and observations to improve on validity and reliability o...
ABSTRACT The study was conducted in the months of July-September 2017 to assess the socioeconomic impacts of the invasive Typha domingensis (Uchytil 1992) on local communities in Nguru, Kakori and Dogon Kuka towns all along the Nguru wetland in Nguru Local Government Area, Yobe State, Nigeria. A total of 171 respondents comprising of local communities and officials of the Hadejia Nguru Wetland Conservation Project (HNWCP) and Komodougu Yobe Basin Wetlands Development Initiative (KYB-WDI) part...
ABSTRACT The study sought to assess the solid waste disposal pattern of sellers in Mile One Market Port Harcourt in order to: identify the solid waste disposal habits of sellers, determine the frequency of clearing dumpsters from the market, determine accessibilityof waste dumpsters to market sellers and ascertain if the pattern of waste disposal significantly vary from different section of the markets.Data wereobtained throughinterviews, questionnaires and on the spot observation. A total of...
ABSTRACT The indiscriminate dumping of urban wastes in surface water bodies in urban and semiurban areas in Nigeria has become a growing menace to humans and natural ecosystem. This study tried to access the effect of urban waste on Mmiriocha river quality located in Abakpa, Enugu state. Water samples were collected at four different points considering various human activities that generate and discharge wastes into the river such as abattoir, raw sewage from homes, open dumps along the river...
