Book excerpt: "The unprecedented rate of contemporary climate warming is affecting ecosystems globally; and inland waters are predicted to be among the most vulnerable as they are already heavily exploited by humans for numerous ecosystem services. My doctoral research examined the effects of climate change on the inland fisheries of continental Africa, with a special focus on the ecological and social consequences for the Lake Victoria basin of East Africa. First, I used a trait-based climate-change vulnerability assessment (CCVA) of African freshwater fishes to document biogeographical patterns of climate change threats across the continent. By integrating species traits with projected climatic changes, I identified regions and species that are most at risk, and demonstrated that nearly 40% of African freshwater fish species are highly vulnerable to climate change. This study was also important in highlighting several cases where classic conservation approaches have overlooked species and regions of climate change concern. In the remainder of this dissertation, I focused on the Lake Victoria basin of East Africa, a region that emerged as highly threatened in the CCVA. In a suite of short- and long-term acclimation experiments, I tested the capacity of a commercially harvested species (the Nile perch, Lates niloticus), to cope with climate change stresses through physiological adjustments of their thermal tolerance limits. I acclimated Nile perch to a wide range of temperatures over various exposure times (3-days, 3-weeks, 3-months), and measured changes to upper thermal tolerance, metabolic performance, growth, and organ development among temperatures and acclimation times. I found that Nile perch showed evidence for compensation in upper thermal tolerance and metabolic rate over all exposure times, and demonstrated that temperature-induced cardiac remodelling influenced aerobic function in this species. The key findings of this work challenge long-held assumptions that tropical species have limited thermal plasticity for coping with climate change-related stressors. Finally, I investigated vulnerability and resilience of fishery-based social-ecological systems in the Lake Victoria basin. Household surveys, focus group discussions, and key informant interviews were conducted in five villages ranging from low to high-dependence of fishing to determine how households and communities are affected by and respond to climate-mediated changes in the fishery. I found that climate change is highly disruptive to fishery-based livelihoods, causing social-ecological feedbacks that tend to entrench households and communities into a singular dependence on an already threatened and declining resource. However, fishers' growing awareness of these interactions can lead to adaptive actions that improve resilience to the ongoing changes in this ecosystem. Overall this thesis provides critical insight into climate change vulnerability of Africa's inland aquatic environments, and highlights several mechanisms that may underlie resilience in fish species and the human communities that rely on them." --

Available in PDF, EPUB and Kindle. Book excerpt: This book employs a suite of remotely sensed products and advanced technologies to provide the first comprehensive space-based sensing of Lake Victoria, the world’s second largest freshwater lake that supports a livelihood of more than 42 million people, modulates regional climate, but faces myriads of challenges. Proper understanding of the lake and changes in its physical dynamics (e.g., water level, shorelines and areal dynamics) resulting from the impacts of climate variation and climate change as well as anthropogenic (e.g., hydropower and irrigation) is important for its management as well as for strategic development before, during and after climate extremes (e.g., floods and droughts) in order to inform policy formulations, planning and mitigation measures. Owing to its sheer size, and lack of research resources commitment by regional governments that hamper its observations, however, it is a daunting task to undertake studies on Lake Victoria relying solely on in-situ “boots on the ground” measurements, which are sparse, missing in most cases, inconsistent or restricted by governmental red tapes. To unlock the potentials of Lake Victoria, this book argues for the removal of obsolete Nile treaties signed between Britain, Egypt and Sudan in the 1920s and 1950s, which prohibits its utilization by the upstream countries. The book is useful to those in water resources management and policy formulations, hydrologists, environmentalists, engineers and researchers. In a unique cross-disciplinary approach, the Book articulates the various climatic impacts and explanations from natural and anthropogenic origins, which affected Lake Victoria and its vicinity, including the drastic increase and depletion of water level in the Lake and dams, floods and droughts, water quality/security, crop health, food security, and economic implications. With no exception as in his many publications, Joseph L. Awange used data analysis methodologies including filtering, adjustment theory, and robust statistics, to quantify the hydrologic and other parameters, and their estimated uncertainties. The Book is recommended for readers from a diverse disciplines, including physical and social sciences, policy, law, engineering, and disaster management. Professor C.K. Shum, Ohio State University.

Download or read book Influence of Climate Change and Human induced Environmental Degradation on Lake Victoria written by Julius B. Lejju and published by African Books Collective. This book was released on 2012 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Victoria basin, an international water body that offers the riparian communities a large number of important benefits, has in the last four decades experienced drastic environmental changes, with a significant drop in its water level in the more recent years. The changes in water level have significantly affected the energy supply in the region and threatened the lives of the riparian population engaged, directly and indirectly, in subsistence and commercial fishing, and the agricultural and industrial sectors. The reduction in lake levels has attracted conflicting speculation. Environmentalists attribute it to reduced rainfall experienced in the East African region, while hydrologists blame it on environmental degradation and excessive water release through the operations of the Kiira-Nalubale hydroelectric power dams at Jinja. This research provides evidence of long-term environment changes in Lake Victoria and a contribution to the understanding of the past environmental conditions in the lake basin. It provides the history of human environment interactions, including the possible cause for the dynamics of the lake levels, giving possible options that can help to remedy and/or mitigate the environmental degradation in the region.

Available in PDF, EPUB and Kindle. Book excerpt: Climate change is having increasing impacts on water, sanitation, and hygiene (WASH) worldwide, rendering health-friendly behaviours less achievable in low-resource settings, disrupting WASH service provision, and reversing global progress on improving WASH infrastructure and controlling waterborne diseases. Much of these impacts are mediated through climate-driven changes in rainfall, which lead to both intensified and lengthier droughts, alongside heavier bouts of rain, and more frequent storms and extreme weather events. The impacts of both extreme and minimal rainfall on water quality and access and on sanitation and hygiene maintenance are myriad and have gained increased attention owing to a growing body of literature presenting important social, health, and environmental consequences. In recent years, a rising number of actors have pointed to the need for climate adaptation to be mainstreamed into the WASH sector, to ensure that WASH services, technologies, practices, and infrastructures are maximally resilient to the impending impacts of climate-driven rainfall changes. In the Lake Victoria Basin (LVB), which encompasses parts of Kenya, Uganda, Tanzania, Rwanda, and Burundi, both WASH and, more recently, climate change have been placed relatively high on the agenda of development bodies. A history of WASH progress in this region has notably reduced waterborne disease incidence, but ongoing threats still produce significant morbidity and mortality burdens. Meanwhile, the region is highly vulnerable to climate change due to a combination of geographic, hydrological, and socioeconomic factors. Not surprisingly, East African governments have had to devote increased attention to climate adaptation goal-setting, as the impacts of climate change on the region become more pressing and the United Nations Framework Convention on Climate Change pushes for regular submission of National Adaptation Plans and National Adaptation Programmes of Action. Given the importance of both climate adaptation and WASH in the LVB context, and the growing impetus for climate-WASH integration, this study sought to assess the progress thus far achieved in integrating WASH and climate adaptation agendas in the LVB, and outstanding barriers to progress. A secondary objective was to better understand how lakeside communities are adapting their own WASH behaviours and practices in response to the new threats posed by climate change-driven changes in rainfall, so that any positive adaptations could be documented, and associated innovations later tapped in regional climate adaptation planning efforts. Through a collaboration with a community-based organization in Western Kenya named Kar Geno- Center for Hope, a quantitative WASH practice survey was conducted, followed by 17 qualitative interviews and 17 focus groups with community members residing in the lakeside village of Mabinju, located in Siaya County. Collaborations were additionally forged with a network of organizations working on WASH and/or climate adaptation in the wider LVB region, from which knowledgeable stakeholders were interviewed. Interviews and focus groups, which were conducted in Luo but translated into English, were recorded and transcribed, and a qualitative thematic content analysis was conducted on all transcripts. This involved inductive coding using Dedoose qualitative data analysis software and a grounded theory analysis framework. The results of the study affirmed the cross-cutting impacts that climate change is having on WASH in the region, at both community and governance levels, and illuminated how it has interacted with other environmental threats to accelerate longstanding trends of environmental degradation and socioeconomic vulnerability. The responses of community members in Mabinju to these impacts were found to be wide in scope, and included both positive and maladaptive behaviour changes. On an institutional level, sectoral siloes and a lack of interdisciplinary collaboration, among other factors related to funding and international priorities, were found to restrain full climate-WASH integration in the region, despite evidence of early progress. Attention paid to sanitation was also found to be notably lacking, paralleling a global trend of disproportionate focus on water within the broader climate adaptation agenda. These findings hold implications for regional climate adaptation planning efforts, and offer global lessons on how governance structures can be made more conducive to climate-WASH integration and on how community knowledge, insights, and innovation potential can be better tapped in the development of novel climate resiliency promoting measures in the WASH sector.
