    Learning for climate change adptation among selected communities of Lusaka Province in Zambia
    (AJOL, 2017-09-03) Muchanga, Manoah
    This research was aimed at surveying perceptions of climate change and educational themes that would be contextually relevant for climate change adaptation. It locates within the United Nations’ Educational, Scientific and Cultural Organization’s (UNESCO’s) Balaclava recommendations on Climate Change Education for Sustainable Development (2013). Uncertainty as to how residents of selected households understood the causes and effects of climate change as well as the content structure of learning for climate change adaptation constituted the problem. Using social constructivism, hermeneutics, survey design, semi- structured interviews and constant comparative analysis, the article shows that the challenges of climate change are comprehended in diverse ways. It also shows that drawing knowledge from diverse sources or cross-disciplines can evoke behavioural and social change that is critical in order to nurture best thinking and practices regarding adaptation.

    Occurence , severity and magnitude of hydrological drought in Zambia :impacts and implications
    (1999) Sichingabula, Henry
    Persistent occurrence of drought under increasing water supply demands for municipalities and agriculture, and under increased threat of global warming, requires increased understanding of drought characteristics and sustainable use of water resources. Using the theory of runs, several hydroiogical drought parameters of frequency of occurrence, run length, magnitude and run intensity, were investigated for the Kafue and Zambezi rivers. Objectives were to (a) determine magnitude-frequency characteristics of hydroiogical droughts; (b) determine some drought run parameters and frequency of their occurrence; and (c) propose a new approach for increasing Zambia's utilization of its water resources without jeopardizing international relations with neighbouring countries. Better understanding of droughts and assessment of Zambia's present and future water requirements will enable planners and decision makers to bring increased economic benefits to citizens. Zambia's drought and water scarcity problems are outlined and linked to some proposed regional water projects designed to divert water from the Zambezi River system. One possible solution to problems of drought and dwindling water levels on Kafue River is proposed.
