CLIMATE CHANGE AND BLUE CARBON: ABOVE-GROUND CARBON STOCK OF MANGROVES IN THE LOWER VOLTA AREA

ABSTRACT Mangroves and other blue carbon systems are under high pressure due to population pressure and coastal development. The continuous degradation of mangroves leads to the loss of the carbon stocks stored in the mangrove ecosystem. In this study, GIS based analysis using Landsat images and allometric equations were used to estimate the above-ground carbon stock of mangroves in the Lower Volta area in Ghana. The Landsat images were classified to obtain the mangrove area. An ASTER GDEM co...

PUBLIC EXPOSURE TO HAZARDS ASSOCIATED WITH NATURALLY OCCURRING RADIOACTIVE MATERIALS IN MINING: DOSE ASSESSMENT AND CANCER RISK ESTIMATION

ABSTRACT Human beings are always exposed to background radiation that comes both from natural and man-made sources. Natural radioactivity is widespread in the earth environment and it exists in various geological formations such as earth’s crust, rocks, soils, plants, water and air. Mining has been identified as one of the potential sources of exposure to naturally occurring radioactive materials (NORM). However, mining activities are not being monitored and regulated for NORM in Ghana. Mos...

THE EFFECTS OF ADRA’S MANGO PROJECT ON LIVELIHOODS IN THE YILO KROBO DISTRICT

ABSTRACT Although recent statistics reveal a decline in poverty in Ghana, many people still live below the poverty line. Rural small-holder food crop farmers are the most vulnerable groups affected by poverty. This is due to their limited access to micro-credits. The Adventist Development and Relief Agency (ADRA) is a Non Governmental Organization in Ghana and has been working with small-holder farmers in the Yilo Krobo District with the aim of improving rural income and improving the well-be...

Reasons for renova...

Evaluation of Isolated Fungal Entomopathogens and Seed Extracts of Piper Guineense Against Larvae of Helicoverpa armigera (Lepidoptera: Noctuidae) in the Laboratory

ABSTRACT A major constraint to increased and sustainable production of tomatoes is its infestation by insect pests particularly the tomato fruit worm Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae). The control of this insect relies heavily on the use of synthetic insecticides which have negative environmental effects. Some insects have developed resistance to certain insecticides. Efforts are therefore being made to look for alternative control strategies that are environmentally-safe...

PATTERNS OF PESTICIDE USE AND RESIDUE LEVELS IN EXPORTABLE PINEAPPLE (Ananas comosus L. Merr.)

ABSTRACT Pesticide use pattern on exportable pineapple (Ananas comosus L. Merr.) (Smooth Cayenne) was studied in the Akwapim South District of Ghana through administration of questionnaires. Among the several pesticides listed as being used, only nine, representing 43%, had been provisionally approved for use on exportable pineapples. Farmers handled pesticides carelessly without necessary caution though they had general awareness of hazards of pesticides. Residue levels of chlorpyrifos...
