Okavango Research Institute (ORI)
Browse by
HOORC, now ORI, is a centre for the study and conservation of one of the world's largest and most intact wetland ecosystem -the Okavango Delta- as well as other wetlands, riverbasins and watersheds in southern Africa. Situated near Maun, Botswana's northwestern Ngamiland capital on the fringe of the Okavango, it specialises in natural resource management research, with a primary focus on influencing policy makers on the region's most pressing environmental issues.

Assessing long-term conservation impacts on adaptive capacity in a flagship community-based natural resources management area in Botswana
(Ecology and Society, https://ecologyandsociety.org/, 2023)Over the past three decades community-based natural resources management (CBNRM) has sought to address the concurrent needs of economic development and ecological protection at the local level, but there is often strong ... -
An assessment of the extent to which agricultural farms meet the requirements for sustainable agritourism in Zimbabwe
(Taylor & Francis, https://taylorandfrancis.com/, 2024)The purpose of this study was to assess the extent to which agricultural farms meet the requirements for sustainable agritourism in Zimbabwe. This study was motivated by the realisation that despite that the country is ... -
Agrotourism as peripheral and ultraperipheral community livelihoods diversification strategy: insights from the Okavango Delta, Botswana
(Elservier, https://www.elsevier.com, 2023)The potential of agrotourism for livelihoods diversification in remote (peripheral) and extremely remote (ultraperipheral) traditional, agrarian communities is indeed a testament of its uniqueness to enhance rural ... -
From sink to source: high inter-annual variability in the carbon budget of a Southern African wetland
(The Royal Society Publishing, https://royalsocietypublishing.org, 2021-05-26)We report on three years of continuous monitoring of carbon dioxide (CO2) and methane (CH4) emissions in two contrasting wetland areas of the Okavango Delta, Botswana: a perennial swamp and a seasonal floodplain. The ... -

(Oxford University Press, https://academic.oup.com, 2021-01-16)We compared diets of marabou storks Leptoptilos crumenifer foraging from urban landfills and natural areas in northern Botswana using stable isotope analyses and inductively coupled plasma mass spectrometry on moulted ... -
Trace metal enrichments in water of the Okavango Delta (Botswana): hydrological consequences
(Wiley Open Access, https://agupubs.onlinelibrary.wiley.com, 2021-05-03)he Okavango Delta in northern Botswana is an endorheic ecosystem formed by 150,000 islands surrounded by a flood plain. The vegetation of these islands displays an external tree ring enclosing a barren interior domain with ... -
Low oxygen: A (tough) way of life for Okavango fishes
(Public Library of Science, http://www.plosone.org/, 2020-07-30)Botswana’s Okavango Delta is a World Heritage Site and biodiverse wilderness. In 2016–2018, following arrival of the annual flood of rainwater from Angola’s highlands, and using continuous oxygen logging, we documented ... -
Physicochemical controls of diffusive methane fluxes in the Okavango Delta, Botswana
(Springer Link, https://link.springer.com, 2015-01-29)Atmospheric methane (CH4) is one of the three key greenhouse gases (GHGs) driving global climate change. The atmospheric concentration of CH4 has increased by about 150 % above pre-industrial levels of 400–700 ppb due to ... -
Local residents’ pride, tourists’ playground: the misrepresentation and exclusion of local residents in tourism
(Taylor & Francis (Routlegde), https://www.tandfonline.com, 2019-05-11)In most studies, Africans and other local residents in the Global South are often considered merely as hosts, and as a result, they are often misrepresented in shaping tourism in their own countries. Using Botswana as an ... -
