Abstract:

Abstract. This study examines the interface between groundwater hydrology and ecology, and addresses a scientific grand challenge to develop a comprehensive, systematic understanding of continental water dynamics by linking the hydrosphere and biosphere. There exists a current lack of data interoperability between groundwater modeling tools due to differences in numerical techniques – Analytic Element Method (AEM), Finite Difference Method (FDM), and Finite Element Method (FEM) – which lend themselves well to either vector or raster data, and legacy input/output file formats that are not well suited across models. Nonetheless, investigative computational tools are all founded in the same conceptualization of hydrologic properties associated with mass, flux, pathways and residence time. A consistent framework is developed using modern Geographic Information Science (GIScience) methods to organize and archive important information from international datasets and previous groundwater ecohydrology studies organized around aquifer and water point, line, polygon and raster features. Case studies illustrate the efficacy of this platform to address existing data interoperability issues for representative groundwater ecohydrology problems of global significance including the impact of human-induced forcings, change in species, and forcings by natural processes on groundwater ecohydrology. In North America, we study the relationships between groundwater pumping in the Ogallala Aquifer and changes in riparian habitat and phreatophyte species composition. In Europe, we study the impacts of changes in forest species composition on groundwater recharge and baseflow to biologically diverse fens and wetlands in the Veluwe sand hill region of The Netherlands. In Africa, we study the wetlands of the Okavango Delta in Botswana that forms an oasis in the midst of the Kalahari Desert and the role of groundwater in flushing salts from this freshwater ecosystem. In each study, we document the current state of knowledge, identify pertinent datasets and previous studies, develop new conceptual and computer models, and summarize findings. This computational platform provides a framework to study sustainability, to forecast the impacts of changes in forcings, and to provide a scientific underpinning that informs management and public policy debate.

Abstract:

In Botswana, tourism is the second most important economic activity after diamond mining and trading. The Okavango Delta in northern Botswana is the largest single tourist centre in the country. This study estimates the total economic value of tourism in the Okavango Delta and compares this value to that of other sectors in the economy of Botswana. The results are compared to results of similar studies for tourist destinations elsewhere in the world, and the policy implications of the findings are highlighted. The study uses secondary data to estimate the direct consumptive and non-consumptive use value, and a survey among tourists to determine the existence value of the Okavango Delta.

Abstract:

Gnathostomiasis is a zoonotic nematode parasite disease, most commonly acquired by eating raw or undercooked fish. Although the disease is well known in parts of Asia and Central and South America, relatively few cases have been reported from Africa. Raw fish consumed in the Okavango River delta area of Botswana, and in nearby western Zambia, has previously produced laboratory-proven gnathostomiasis in tourists. The purpose of this communication is to record additional cases of the infection acquired in the Okavango delta, and to alert visitors to the inadvisability of eating raw freshwater fish in the southern African region.

Abstract:

Purpose – Climate change continues to pose a serious challenge to mankind. Given their socio-economic and vulnerable situations, resource-poor farmers will be hard hit and likely to be the most affected group in Africa – a continent that will bear the full brunt of inclement weather conditions. The purpose of this paper is to address the questions of how local farmers read and predict the weather, and how best they can collaborate with weather scientists in adapting to climate change and variability in the Okavango Delta of Botswana. Design/methodology/approach – A multi-stage sampling procedure was employed in sampling a total of 592 households heads (both men and women) in eight rural communities in the Okavango Delta, Botswana. Findings – Analysis indicates that about 80 per cent of the farmers had a good knowledge of weather forecasting. In a knowledge validation workshop organised and implemented in early August 2012, farmers and scientists identified a nine-point agenda and strategies for addressing the challenges posed by climate change to community well-being and agricultural production. Knowledge sharing, installation of community weather stations and local-level capacity building are amongst the strategies identified. Research limitations/implications – The research is only limited to the Okavango Delta, Botswana. Originality/value – The paper emanates from original field research. The outcome of the paper provides pertinent information for policy formulation on how best to enhance small farmers’ adaptation to climate change.

Full text

Abstract:

Managing any inland fishery requires reliable age data and accurate estimates of growth rate. Clarias gariepinus, the largest catfish species in most tropical African floodplain river systems, is an important constituent of subsistence fishery catches. We used otolith-derived age estimates to describe patterns of age and growth for C. gariepinus from the Lower Okavango Delta in northern Botswana. Edge analysis of sectioned sagittal otoliths showed that growth zone deposition occurred during the annual flood peak between July and September. The maximum recorded age was 8 years. Growth was best described by the von Bertalanffy Growth Model of the form E[L|age] = 528.70(1–e–0.72(age+1.35)). A comparison of growth parameters from this study with those from previous studies suggests two distinct populations of C. gariepinus between the Upper and Lower Okavango Delta, emphasising the importance of regional stock assessment for key fishery species. The fairly short life span and high variability in growth of C. gariepinus are important indicators that it is imperative to maintain natural habitat and flow regime for sustainable management of fishery resources in the Lower Okavango Delta.

Abstract:

Desiccation of river channels, resulting from low inflows, is among the major shocks affecting household livelihoods in the Okavango Delta, Botswana. Household coping and adaptive strategies against this shock are believed to be inadequate owing to changes in policy, land use and environmental conditions. This paper aims to improve knowledge on household capacity to adapt to desiccation in the Okavango Delta. It identifies and assesses the impacts of desiccation on rural livelihoods, the household strategies, and the impacts of institutional changes on household responses. Informed by the sustainable livelihood and socio-ecological frameworks, the study used a survey of 526 households and other qualitative methods. The results show that desiccation adversely affected livelihood activities. Household responses included livestock relocation to wetter areas, livelihood diversification, digging of wells and boreholes, and switching from flood recession to rain-fed cultivation. Land use and institutional changes inhibited household adaptation to desiccation. Additionally, households did not sufficiently use opportunities resulting from desiccation. The study concludes that the ability to capitalise on opportunities created by climatic shocks needs to be developed at all levels, as this can improve adaptation to the impacts of, and reduce losses from, future climate variability and change in Botswana and other developing countries.

Abstract:

Drying floodplains that were not inundated for more than 10 y were investigated to relate plant species and vegetation structure to time-since-fire for the southern Okavango Delta wetland in Botswana. The aims of the research were to study post-fire succession on savanna habitats in the Okavango Delta and to investigate the mechanisms behind vegetation changes with time-since-fire. We hypothesize that vegetation structure rather than species occurrence is affected by the fire event and that the driving forces of post-fire succession change from fire-driven to competition-driven with increasing time-since-fire. A total number of 153 study sites were investigated, representing areas of 2–12 y without a fire. Both woody and herbaceous plant species were recorded and cover/abundance values were measured. The vegetation changes with time-since-fire could be assigned to three different successional stages: (1) the post-fire conditions shortly after fire, supporting high species numbers due to open space and little competition; (2) the dominance of competitive perennial grass species (e.g. Urochloa mosambicensis) after 6–8 y; and (3) the enhanced establishment of woody species after about 10 y, creating new habitats in their vicinity. High species numbers were found after short and long fire-free periods, and different species occurred shortly after the fire event and at late stages of the post-fire succession. A variety of different inter-fire intervals is therefore expected to be responsible for sustaining plant species richness and habitat diversity in the study area. Post-fire succession could be described as not only being driven by the life history of the species, but also by seedbank dynamics and plant mobility in early successional stages and by competition and niche differentiation in late-successional stages.
