Net Surface Shortwave Radiation (NSSR) is a key quantity for the estimation of net radiation (đť‘…đť‘›) and đť‘…đť‘› 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...
ABSTRACTÂ 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...
Abstract Apparently Gabiley District undergoes water crisis where the demand of water outstrips the available water. This has resulted in number of consequences in various aspects in the life of the people, but most importantly hindering their agricultural productivity despite the agriculture contributes 70% of the economy of the county as the people predominantly graze animals (goat, sheep, camel, cattle). However, the major purpose of this study was to examine the Impact of prevailing water...
ABSTRACT Seaweed has many uses which including source of food, in agriculture is used as organic fertilizer and also has been used in medicinal products. However, seaweed farming has side effects on environment and most coastal communities who involved in this farming do not well know. The general objective of this study was to assess environmental impacts of seaweed farming. The specific objectives of the study were including; to identify types of seaweed and activities related to seaweed f...
ABSTRACT This study investigated hospital solid waste management systems and practices at University Teaching Hospital of Kigali (CHUK) for improving environmental management by promoting the safe and appropriate management of waste from hospitals. A combination of quantitative and qualitative methodologies was used to record necessary information. Data were analyzed with SPSS version 18.0 statistical software. Student t test and chi-squared tests were mainly applied to assess the data. The r...
ABSTRACT Gas flaring is one of the associated activities of the oils and gas industry, which poses negative impacts on the environment such as climate change, impact on health and economic loss. The Nigerian government has tried putting a stop to gas flaring but to no avail, there is a continuous flaring of gas by oil companies operating in the Niger delta. Â This research answers the question of the volume gas flared by Oil Company and also the increased or decreased volume flared. The re...
ABSTRACTÂ This study was conducted in Itaphe hills in Kogi state and Birnin Gwari in Kaduna state, Nigeria to assess the effects of mining activities on land cover changes. There is a conflict between economic gains as a result of mining activities on land cover changes resulting in environmental degradation. Therefore this study was an attempt to fill the existing knowledge gap. According to Kibuuka M, (2012), research Gap(s) is a problem which has not been addressed so far in this particul...

ABSTRACTÂ The pattern and profile of energy use prevailing today raises important questions about linkages between energy and the economy, social issues, security and above all, environmental protection. Rwanda has a number of potential energy resources from biomass, hydro, solar, petroleum, methane gas, wind and geothermal. However, the major issue in this regard is the technological exploitation and scientific data on this potential. The widespread and inefficient use of traditional biomas...
ABSTRACTÂ This study was undertaken to determine the quality of water by determining the e physicochemical parameters, chemical parameters and bacteriological properties of piped water, and boreholes water in Dar es Salaam city, as well as determination of the seasonal variation of raw water quality. Piped water samples were purposively collected at the point of treatment to the point of use. However all the operational boreholes water samples were sampled. Chlorine, conductivity, temperatur...
