Remote sensing based tech being introduced in Pakistan to forecast floods


Remote sensing based climate and flood warning technology is being introduced to upgrade flood management. This project will help build the capacity of Pakistan Meteorological Department and other agencies responsible for flood forecasting, early warning and management at the national, provincial and district levels.
This could be a milestone in achieving the better capacity to mitigate extreme floods not only in areas like Pakistan but even in Africa where flooding is a constant phenomenon. The article is available at:http://www.thenews.com.pk/NewsDetail.aspx?ID=20594&title=High-tech-sys-to-forecast-floods

Fieldwork along the Southern Buffalo fence between Habu and Matsibe




HOORC staff recently spent 9 days in the field collecting data on woody vegetation at 20 pairs of transect either side of the buffalo fence, as part of a study on "Fence Induced Change in Biodiversity and Range Quality in the Southern Okavango" with implications for policy and management. The team comprised of Lin Cassidy, Richard Fynn, Bongani Sethebe, Thebe Kemosedile, Senhenyi Tlotlego and Mompati Kupe. Information on plant species and structure was collected to establish differences in diversity of woody plants between the two sides of the fence. The timing for the field work was excellent, with most of the plants either flowering of fruiting, facilitating identification. Grewia berries provided the team with extra energy as they spent hours every day walking and recording in the blistering heat. Bongani Sethebe also used this time to collect unusual plant museums for the herbarium. Other field trips on this study have focused on collecting soil samples, conducting training samples for ground truthing satellite imagery, collecting herbaceous layer samples to assess nutrient quality and grass species, and undertaking a bird survey. the results of this data will be used in the overall assessment of the degree to which vegetation inside the fence has changes as a result of the truncation of wild animal movements.

Web based community based GIS applications


As resource managers search for strategies to meet the challenges posed by intense competition for scarce local resources, the implementation of Community-based GIS applications have become widespread. Besides mapping, the Participatory GIS (PGIS) projects create a peaceful medium for community groups and public officials to meet, exchange views and also learn to develop trust for each other. However, PGIS projects face many problems including the lack of basic supporting infrastructure and services. The adoption of the Internet as a platform for PGIS applications therefore raises concerns about the future of PGIS projects. While the Internet may open the participatory process, it can also hinder participation among local groups. In an era when PGIS applications have become important in the management of local resources, there is an urgent need to examine implications of the On-line PGIS project. Accordingly, in their paper, Dr. Peter Kyem and Dr. James Saku assess the potential benefits and drawbacks of on-line PGIS applications within local communities. Full report available on

7th Southern Africa Fire Network (SAFNet) Workshop

The 7th Southern Africa Fire Network (SAFNet) Workshop will be held in Caprivi, Namibia on 22-26th September 2008. The workshop, Towards Effective Regional Fire Management, Policies and Operations Status aims to foster more effective and appropriate fire management policies and practices in Southern Africa through the use of remote sensing, GIS and other geo-spatial information technologies. Fire monitoring and research remains sporadic and fractured in Southern Africa, as is the case for the rest of the continent. Building capacity on fire research, generation of up to date fire information and formulating informed fire management policies and strategies are key to sustainable development and climate change mitigation and adaptation in Africa.

The workshop will include a demonstration on controlled burning and training sessions on the use of MODIS and Landsat satellite fire products for operational fire management.

The workshop organizers are calling for abstracts for oral presentations and posters. Those who wish to be considered for training sessions should provide their CV and a brief explanation on why they need this training. Abstracts and applications for training should be forwarded by 25th July 2008 to: Mark Tadross, University of Cape Town, South Africa with a copy to Opha Pauline Dube, University of Botswana.

LandSat TM mapping of mopane

Mapping of colophospermum mopane using Landsat TM in eastern Botswana recently published in the South African Geographical Journal by Reuben J. Sebego, Wolter Arnberg, Bengt Lunden and HOORC researcher Susan Ringrose, reports results of a study of the range of mopane trees and related soils in Botswana. Methods applied in the exercise used the possibilities of integrated applications of geographic information systems and remote sensing to detect and delineate spectral classes of C. mopane and of soils. Results demonstrated the utility of CIR photographs in selecting training areas for the classification of Landsat TM imagery, that Landsat TM can be used to map the distribution pattern of mopane, that the much needed inventorying of vegetation in Botswana can be carried out using remote sensing, and that spectral classes of soil and vegetation have a positive relationship. You can find the article in HOORC's Library.

New in HOORC's Library: remote sensing dissertation

Landcover classification product aggregated to vegetation type from Neuenschwander dissertation
Remote sensing of vegetation dynamics in response to flooding and fire in the Okavango Delta, Botswana, Amy Neuenschwander's PhD dissertation for the University of Texas at Austin, assesses the spatio-temporal distribution of flooding and fire and their subsequent influences on
vegetation as represented by vegetation index trajectories in the Okavango Delta. The work's characterization of spatio-temporal distribution of flooding and fire regimes with the temporal dynamics of vegetation spectral response via a time-series of remotely sensed data informs ecosystem and disturbance theory and presents new methodological applications for
multi-temporal change analysis. You can find the dissertation in HOORC's Library.

Remote sensing of groundwater programmes

The World Resources Institute's Earthtrends weblog has a story about NASA's Gravity Recovery and Climate Experiment (GRACE) that has predicted river flows and freshwater storage continuously since 2002. Recent data from the project showed drying along the Zambezi and Nile basins in Africa. GRACE measurements have also been able to predict water availability for farmers in the Lake Chad basin. In Botswana, the European Space Agency's TIGER Initiative project is supporting Remote sensing as a data source for surface and groundwater modelling in Botswana, a Botswana Department of Water Affairs / HOORC study of connections between Okavango swamp and groundwater, the faulting and thickness of the Kalahari sandbeds and topology and topography of the Okavango Delta's channel network.
