ABSTRACT The impact of climate change is now posing a greater threat on the hydrological cycle leading to drought and water stress in small basins. Matters of climate change have now become a primary concern to most nations due to the implication on society and humanity. The study used 17 ensemble climate model from the Coupled Model Intercompersion Project Phase 5 (CMIP5) to estimate the future climatic condition for the 2050s (2035 to 2065) under Representative Concentration Pathways (RCP) ...
ABSTRACT A sufficient, clean drinking water supply is essential to life but millions of people throughout the world do not have access to this basic necessity. Even after the intensive efforts of engineers, planners, builders, governmental and non-governmental organisations (NGOs) to bring potable water to the poorer people of the world, the situation is still a challenge. The problem becomes exacerbated especially in developing countries with an increasing population growth trend. This study...
ABSTRACT Agriculture, which is the main source of livelihood of peri-urban dwellers in Sekondi-Takoradi Metropolis is seriously being threatened by rapid urbanization due to the discovery of oil in the Tano Basin.
