    The climate change challenge in Africa:- impacts, mitigation and adaptation
    (Asian Economic and Social Society, 2012) Adebamowo, M.; Uduma-Olugu, N.; Oginni, A.
    Climate change is now a reality, and is already having devastating effects on the natural environment and human populations across the world. Many studies (Maathai, 2006; UNFCC 2006; CCDI 2007; IPCC 2007 and UNDP 2009) have confirmed that Africa contributes the least to global warming but the region is the most vulnerable and most adversely affected by climate change. Unpredictable rains and floods, prolonged droughts, subsequent crop failures and rapid desertification among others have in fact already begun to change the face of the continent. Africa’s poor and vulnerable will be particularly hit by the effects of the rising temperatures. This paper examines the problem of climate change in Africa; its impacts, mitigation and adaptation measures are equally investigated. The paper explains that neither mitigation nor adaptation alone can avoid significant impacts but together they can compliment each other and reduce significantly the risks of climate change. Finally it concludes with recommendation to African Countries to enable them reduce vulnerability and increase capacity to adapt while suggesting the need to integrate climate change concerns into all planning whether it be infrastructure, education or health.

    Reducing heat-load in buildings through the use of solar screens: Case study of bookshop house, Lagos
    (David Publishing Company, 2012) Adebamowo, M.; Godwin, J.; Oginni, A.
    Abstract: Technology advancement has ensured a better means of livelihood essentially in certain parts of West Africa, specifically Nigeria, where the climate is predominantly hot in most parts throughout the year. Air-conditioning has reduced the harshness of indoor discomforts to the barest minimum. It is no more uncommon to find it regularly in use in most homes and offices. Currently, theeconomy has the centrality of its power supply hinged on generator plants. The enigma of the current situation is how this alternative problem has catastrophic after effects on the environment. This and many more add up to the greatest of all the threats now evading our environment and the world — Global warming. The threat of Global warming is real and the need to find less environmentally destructive sources of energy cannot be overemphasized. This paper is a contribution towards energy saving in buildings through the reduction of solar radiation incident on buildings. Sustainable Building calls for an integrated planning approach for operating buildings economically, substantially reducing their impact on the environment by reducing energy/power consumption, amongst others, and enhancing the well-being of their inhabitants. Only buildings that reconcile all of the above factors are fit for the future. A case study of the CMS (Catholic Mission School) Book Shop house in Lagos was carried out. The methodology involved the use of asolar chart and shadow angle protractor to determine the overheated periods represented by the shading masks and data collected. From this analysis, it was decided to accept the use of external sun shading and preliminary designs and specifications were prepared by the architects. The use of external solar screens made a saving of up to 75% of the energy input which would otherwise have been required by air-conditioning.
