Over the years, many countries across the world have increasingly experienced the collapse of their ecosystems, leading to an elevated increase on the demand for freshwater resources. Botswana is not an exception. The problem of disrupted potable water supply is widespread across the country. However, the physical shortage of water in the country is arguably coupled by lack of effective and efficient water supply and management institutions and water infrastructure. Most of the research on water scarcity in Botswana is mostly inclined towards physical water scarcity, while little is investigated on how the design of institutions for water management in developing countries leads to water scarcity. Furthermore, the premises of most research is neoclassical economics ideas, thereby offering solutions as developing and/or reforming water markets and water pricing mechanisms, among other findings. This paper analyses potable water supply and access in Botswana within a new institutional economics paradigm. The study examines key features of water institutions in Botswana on how they affect water supply and access, applying new institutional economics fundamentals. The study extensively uses various secondary data sources including weather and climate reports, policy documents, maps and charts and survey data, among others. The paper argues that to achieve effective water allocation in Botswana, there is a need to balance social and environmental water resource needs through water policies and other statutory enactments, as well as the crafting of practical management strategies. The country, therefore, requires not only a swift institutional transformation in the water sector, but also needs practical governance structure necessary for implementing integrated water resources management and driving water resources towards sustainability.

Tourism is an important economic sector in the Global South. It is however vulnerable to the risks and variations associated with global climate change. The paper qualitatively investigates how issues surrounding uncertainty in the climate change discourse have influenced policy makers' response to climate change in Botswana's tourism sector. The analysis of the empirical data derived from in-depth interviews demonstrates that some policy makers remain skeptical about climate change and its impacts on tourism despite growing evidence from regional scientific research and the Intergovernmental Panel on Climate Change (IPCC). Constraints that hamper progress in policy response measures include inadequate knowledge of, and the extent to which, climate science can be trusted. [ABSTRACT FROM AUTHOR]

Central parts of southern Africa are expected to face major environmental and economic changes in the near future, calling for proactive thinking on how local people could diversify their livelihoods. In Botswana, the tourism industry is considered as a major option for economic diversification and current tourism policies include a strong emphasis on tourism that participates in and benefits communities. The developmental impact of tourism depends on how the local communities perceive their livelihood options and the role of tourism. This paper analyses how community members in selected villages in Kalahari Desert perceive the current and estimated future impacts of climate change and how these impacts may influence their livelihoods in future and what role the tourism industry may play in that process. Based on the results, there are minimal local benefits and participation in tourism, which limits the potential of tourism to work for sustainable local development in practice.

Climate change and variability threaten the sustainability of agricultural and food production, especially in agrarian communities. In Southern Africa, rainfall is expected to decline by almost 10% by the year 2050 and the largest increase in temperature can be experienced. Despite the potential risks of climate change on agricultural productivity, Botswana does not have a dedicated policy to respond to climate change. Furthermore, there is a dearth of research done in Botswana to provide an understanding of factors that shape farmers' adaptation to climate change and institutional link to the adaptive capacity of farming households. Therefore, the aim of this article is to analyse institutions that influence farmers' adaptation strategies of farmers in Botswana, using Ngamiland East as a case study. The paper relies on empirical data collected from purposively selected key informants and 300 households. The results show that the majority of farmers who have climate variability adaptation strategies in place are largely influenced by indigenous knowledge. Women and low-income earners are less likely to employ climate change adaptation strategies in order to improve their agricultural productivity. This article gives a better perspective of the strengths, weaknesses, opportunities and threats facing institutions designed to enable agricultural productivity. It recommends that macro-level and local government institutions should acknowledge the indigenous knowledge, community-level institutions and farmers' adaptive capacity in policy formulation processes.

Climate change will impact rural livelihoods in Southern Africa in unprecedented ways. Successful responses must account for intersecting social and ecological factors that determine natural resource access for people living in changing social-ecological systems. However, much of the existing scholarly literature treats natural resource access as a dynamic social process, while often failing to account for how it is also ecologically variable. The social-ecological systems literature more holistically considers social and ecological aspects of resource use, but rarely considers how livelihoods themselves are social-ecological. This paper advances the argument that livelihoods are a useful entry point for understanding the complex and intersecting social-ecological factors that impact natural resource use. Findings are presented from a mixed-methods research project in the variable wetland environment of the Okavango Delta of Botswana to show how participation in various fishing practices is determined by a complex combination of flooding variability, environmental governance, and social relations tied to gender and ethnicity. This article contributes to the literatures on natural resource access and social-ecological systems, increases knowledge about rural livelihoods in Botswana, and provides broader insight into how governance of social-ecological livelihood systems throughout southern Africa are likely to be challenged by climate change.

Purpose – This paper aims to report on the results of a case study in Botswana, aimed at raising awareness on climate issues. Higher-education institutions play a leading role in sustainability efforts, as their research role often lays the groundwork for social transformation. Design/methodology/approach – The Clean Air-Cool Planet (CACP) campus calculator was used to calculate emissions from various sections within the college. Findings – Total greenhouse gas (GHG) emissions from the college is 3,432.66 metric tons CO2e resulting in per capita GHG emissions of 3.20 metric tons CO2e, which is high compared to other universities. Options for reducing emissions are proposed. Practical implications – The procedure in carrying out the study provided learners with an opportunity to appreciate emissions from developing countries and also gain technical skills in conducting a GHG inventory. It also sensitized campus administrators about the scale of emissions and possible ways of reducing them. Originality/value – This paper is original in that it provides campus greenhouse inventory within a developing country, a unique undertaking. Furthermore, it highlights the fact that developing countries also produce significant emissions, hence the need for mitigation measures. [ABSTRACT FROM AUTHOR]

Abstract: Climate change is expected to alter rainfall regimes across most parts of the world. The implications of this could be more severe in arid environments where rainfall is limited and highly variable in space and time. However, lack of good quality data, of sufficient record length and spatial coverage usually restricts model development and performance geared towards assessing the effects of climate change in these areas. This paper presents an analysis of rainfall and climate data in order to determine the time of change in rainfall series and identify possible correlations between rainfall and temperature. In addition, the paper aims to make predictions of future rainfall patterns in Botswana. This is achieved by using historical rainfall and climate data from rainfall stations spread across Botswana from 1965 to 2008. In addition, large scale reanalysis data from NCAR/NCEP and El Nino Southern Oscillation (ENSO) data were used to augment the limited observed spatial climate data series when developing a rainfall model. Temperature and ENSO indices have been used to predict rainfall regimes for the present climate. Based on these, the effects of climate change were quantified using a stochastic generalised linear rainfall model (GLM) driven by outputs of global climate models (GCMs). The results indicate that temperature is a significant rainfall predictor in Botswana compared to ENSO indices. [Copyright &y& Elsevier]

Abstract: Rainfall variability is an important feature of semi-arid climates, and climate change is likely to increase that variability in many of these regions. An understanding of rainfall variability and trends in that variability is needed to help vulnerable dryland agriculturalists and policymakers address current climate variation and future climate change. The goals of this paper are to examine this climatic phenomenon in semi-arid Botswana, to investigate these results for signs of climate change, and to explore the policy implications for climate adaptation. To reach these goals, the paper determines rainfall variability and monthly and annual trends in that variability. The results agree with earlier work showing gradients in rainfall and rainfall variability across Botswana. The results also identify a trend towards decreased rainfall throughout the nation, which is associated with decreases in the number of rainy days. Both the drying trend and decrease in rainy days agree with climate change projections for southern Africa. The paper discusses policies that the government could adopt to help its farmers adapt to climate change. [ABSTRACT FROM AUTHOR]

Tourism is a key sector for most southern African economies endowed with unique natural capital, and the industry is increasingly being used for socio-economic development and diversification of national economies in the region. However, it has become clearly evident that the natural capital upon which the sector depends is highly vulnerable to climate change. This has created urgent governmental needs to take action through policy formulation and implementation. The paper uses in-depth interviews to determine Botswana policy-makers’ perceptions of climate change and tourism with the aim of determining policy needs and constraints. The results reveal that the policy-makers do see climate change as a concern requiring urgent establishment of relevant policy. However, they foresee inadequate information as well as uncertainties surrounding the impacts of climate change on the natural capital. This may hamper the formulation and effective implementation of such a policy. [ABSTRACT FROM PUBLISHER]

The rise in world population growth and its attendant rise in demand for food and living standards in addition to climate change scenarios continue to warrant the need for sustainable management of natural resources. The paper, therefore, analysed climate change actions and water demand management approaches employed by Botswana Stock Exchange (BSE) listed companies to manage water resources. Fourteen of the twenty-four domestic companies were reviewed using self-completed, open ended questionnaires and secondary data. Thematic Analysis method of qualitative research was employed to analyse the textual data. The results revealed that water demand management (WDM) practices and strategies among companies ranged from, rainwater harvesting, water reclamation and reuse, water efficient fixtures and appliances, awareness/knowledge creation strategies and risk management. The unearthed information on private companies' holistic water use strategies could facilitate environmental sustainability and operational economic gains. • Limited water resources compel private sector to practice Water Demand Management. • Examples include rainwater harvesting, water reclamation and reuse. • Stock exchanges assist in shaping company's responses to water scarcity. • Climate action is an integral component of Water Demand Management.

This paper assesses the role of livelihood diversification in household adaptation to flood variability in the Okavango Delta, and locates it within the global discourse on adaptation to climate variability and change in developing countries. The contribution of livelihood activities to household income, level of livelihood diversity and the relationship between livelihood diversification and adaptation to flood variability was determined. Data from a survey of 623 households in five villages, focus group discussions and key informant interviews confirmed livelihood diversification as an important strategy for household adaptation to flood variability in the Delta. However, the household income portfolio was dominated by public transfers, underscoring the weak socio-economic status of the households and the effects of multiple shocks over and above flood variability. The study concludes that livelihood diversification and other household adaptive strategies may be sufficient for current flood variations, but may be inadequate for dealing with global climate variability and change in future.

The natural resources of the Okavango Delta, a large wetland in semi-arid Botswana, form the basis of livelihoods of the local population and support economically important high-end tourism. The hydro-ecological system is dynamic at various time scales, responding to climate variability, and both flood and drought conditions have in the past put pressure on the system's users. Human-induced climate change can potentially exacerbate the effects of existing climate variability. In this paper, we present simulated future hydro-ecological conditions in the Okavango Delta generated by a step-wise modelling procedure. The outputs of three different global climate models are used to drive a suite of hydrological models. Lastly, a rule-based dynamic model relates hydroperiod conditions to vegetation assemblages. The simulated future conditions vary from much drier to much wetter than those recorded in the past. Models indicate that climatic change would result in change in both extent and distribution of the major ecotopes of the Okavango Delta. Importantly, the different ecotopes will be affected to varying degrees. The projected changes will have consequences for the wildlife-based management of the system. They will affect, for example, available grazing and migration/movement patterns of large herbivores, as well as fish. Such consequences can have rapid up-trophic level effects, ultimately leading to potentially substantial impacts on the economy. The main conclusion to be drawn is that management planning and land-use systems should be as flexible as possible. [ABSTRACT FROM AUTHOR]
