Climate change has evolved in an unpredictable trend and droughts have occurred more and more severely in the central provinces of Vietnam. Determining the irrigated area and water requirement for various crops and the growth stage of each crop is an urgent need as water resources for irrigation are getting scarce year by year. This research examines the application of Sentinel-2 and Sentinel-1 images to map crop areas and identify the current development stage of paddy rice areas. The images are collected and pre-processed from 2017 to 2018 for Ha Tinh Province in Vietnam. The Maximus Likelihood method is used to interpret Sentinel-2 imagery for mapping agricultural crop distribution status. The research presents a new approach for identifying rice maturity using the Sentinel-1 image series. The Overall Accuracy (OA) and Kappa coefficient methods are used to evaluate the generated maps of the agricultural crop’s distribution status. This study shows the relationship between the Sentinel-1 VH band and the growth of rice. From the image bands, we could calculate the slope of the line correlating between the VH backscattering value and the growth time of rice. Along with the local planting schedule, rice life cycle, and simple deduction, we could determine the rice growth stage at each time of image acquisition. The results identifying the rice maturity progression are illustrated for Cam Hoa commune in Cam Xuyen district and Thach Hoi commune in Thach Ha district, Ha Tinh Province.

This paper examined the influence of local governance on residents’ environmental sanitation behavior in Ile-Ife, Nigeria. This was with a view to suggesting policy response in furtherance of a sustainable environmental behavior among residents in the city and others with similar background. Four residential zones were identified in the study area. A total of 2,881 buildings were identified comprising 739, 154, 357 and 431 respectively in the low income, middle income, high income and post crisis residential area. One out of every 10th residential building was sampled in each residential area. A total of 288 residents were selected for survey using systematically sampling technique. The study revealed that residents’ socio-economic characteristics varied significantly across residential areas. The study also found that there is low level of access to environmental sanitation facilities/services in the low income, middle income and post crisis residential areas. The study established that a relationship exist between residents’ environmental sanitation behavior and their place of residence. The study also established a variation in the level of agreement of the functions of the mandated monthly environmental sanitation exercise. In general, the maintenance of dumpsites within the city by government was not satisfactory to the residents across the four identified residential areas. The study recommended a synergy of strategies among environmentally-concerned institutions in the study area in provision of facilities/services, environmental awareness and enforcement of sanitation legislations in the study area.

Background. This study examines factors responsible for poor environmental health among vulnerable residents of Ondo, Nigeria. This was with a view to suggesting policy response capable of enhancing healthy environment in the city and others with similar background. Materials and Methods. Systematic sampling was used to collect data from a total of 196 households having stratified the study area into the high, medium and low densities residential neighbourhoods. Both descriptive and inferential statistics were utilized. Results. Findings showed that low government intervention was the most important factor responsible for poor urban environmental health in the study area. Results showed that environmental factors are significantly related to health situation of vulnerable people in the study area. Conclusion. The study concluded that poverty tends to breed poor environmental and unhygienic conditions that have great impact on human health. The study therefore suggests some policy guidelines, including redevelopment (in some parts of the study area), upgrading and provision of basic infrastructural amenities and facilities.

This research aimed to study the bioactivity of crude extracts of stem bark of Vetillariaparadoxa “Shea-nut tree” as used in traditional medicine for treatment of stomach ache and control of diarrhea, using hexane, acetone and ethanol as the extraction solvents. Phytochemical screening of stem bark of extracts of Vitellariaparadoxa revealed the presence of alkaloids, steroids, phenolic compounds, flavonoids, saponins, tannins, and cardiac glycosides. Ethanol, acetone, and hexane extracts inhibited the growth of pathogenic Escherichia coli, salmonella typhi, and staphilycoccusaureus with varying degrees of activity with the ethanol extract demonstrating the highest activity against all the tested bacterial organisms.

These days, the building and construction industry is a main provider to the source of national economy in most countries. Though, incorrect construction waste management lead to numerous difficulties such as prohibited dumping along the roadsides, demolition waste and disposal of construction at landfills as Malaysia is facing severe deficiency of landfill space and lately the matter has developed more serious through the country, which these have caused major government sources and environmental problem. Sustainable waste management aids construction key players to diminish and making better use of material on their construction project. The waste minimization strategy is not only implemented during the construction stage, but it record and estimates the use materials through whole project delivery process. This paper will discuss and elaborate on waste minimization and management in the context of Malaysian construction sector. Waste minimization plan is necessary to reduce present and future risks to human health and the environment which presents guidelines that can be used by professional personnel and organizations to decrease the amount and perniciousness of wastes generated.
