Recent research from HOORC

Water resources management model for Okavango River Basin from Kiker, Munoz-Carpena, Wolski, Cathey, Gaughan and Kim article

Published results of research by HOORC staff and associates recently added to the HOORC Library catalogue cover a wide range of topics relevant to management of the Okavango.

A study reported in The effects of soil cover on soil respiration and microbial population in the mopane (colophospermum mopane) woodland of North Western Botswana by Mabiletswane P. Siele, Tabo Mubyana-John and HOORC ecologist Casper Bonyongo in Dynamic Soil, Dynamic Plant found that fungi contribute significantly to soil structure and respiration under mopane tree canopy.

HOORC Deputy Director Moses Chimbari and C.J. Shiff's investigation of the potential use of the fruit of Jatropha curcas to kill snails that transmit schistosomiasis, A laboratory assessment of the potential molluscicidal potency of Jatropha curcas aqueous extracts, was published in the African journal of aquatic science.

Incorporating uncertainty into adaptive, transboundary water challenges : a conceptual design for the Okavango River basin by Gregory A. Kiker, HOORC researcher Piotr Wolski and associates, published in the International journal of risk assessment and management, explores models for management of transboundary water issues in the Okavango River Basin.

HOORC researchers Philippa Huntsman-Mapila and Susan Ringrose joined associates Tiercelin, Benoit, Diskin, Cotten and Hemond in investigating the origins of the formation of the Okavango's alluvial fan, reported in the African journal of earth sciences, Sediment geochemistry and tectonic setting: application of discrimination diagrams to early stages of intracontinental rift evolution, with examples from the Okavango and Southern Tanganyika rift basins.

HOORC researchers Susan Ringrose, Philippa Huntsman-Mapila and Cornelis Vanderpost also contributed to a study of changes in sediments that sheds light on palaeo-environmental change in the Okavango, reported in Diagenesis in Okavango fan and adjacent dune deposits with implications for the reccord of palaeo-environmental change in Makgadikgadi - Okavango - Zambezi basin, northern Botswana in the journal Geomorphology.

HOORC associate Michael Heinl collaborated with Mike Murray-Hudson, Jan Sliva and Budzanani Tacheba to find that fire plays a secondary role to flooding in affecting vegetation structure and tree density in the Okavango floodplain, reported as The relevance of fire frequency for the floodplain vegetation of the Okavango Delta, Botswana in the African journal of ecology.

HOORC researchers Ketlhatlogile and Belda Mosepele worked with associates Peter Moyle, Glenn Merron and David Purkey to write Fish, floods, and ecosystem engineers : aquatic conservation in the Okavango Delta, Botswana in Bioscience, an argument for fisheries as a key issue when analysing environmental flows in the Delta.

Communicating integrated water resources management : from global discourse to local practice -- chronicling an experience from the Boteti River sub-Basin, Botswana by Larry Swatuk and HOORC researcher Moseki Motsholapheko, published in Physics and chemistry of the earth, reviews the challenges of influencing opinion and beliefs in the context of integrated water resources management.

The same issue of Physics and chemistry of the earth, edited by HOORC researcher Dominic Mazvimavi, featured an article by Mazvimavi and HOORC environmental chemist Wellington Masamba, Impact on water quality of land uses along Thamalakane - Boteti river : an outlet of the Okavango Delta, calling for increased monitoring of fluctuations in water quality of the rivers flowing from the Delta.

You can find all these resources in HOORC's Library.
