Aim: - Build capacity in Assessing Impacts of Climate Change - Provide a pool of locally relevant information on: Impacts of Climate Change on food and Water, The degree of vulnerability & the capacity to adapt to climate change in the Limpopo basin locally based adaptation strategies & how these can be enhance Overall goal: Assist decision makers and international efforts to address climate change impacts, vulnerability& adaptation
Kgatleng District Site
Why Limpopo Basin? • One of the 5 largest surface water bodies in sub-Saharan Africa found in Southern Africa - covers 3720 000 km2of Bots., Zim., SA & Mozambique. • Subjected to frequent climate extremes e.g.:1991/92 droughts & the 1999/2000 floods. • Forms all river systems in eastern Botswana - Major source of water and alluvial deposits for >70% of rainfed and irrigation agriculture. • Over half of Botswana’s population and major urban growth centres occur in the Limpopo Basin

General Questions: • What will be the impact of climate Change on food and water in the Limpopo Basin? • How vulnerable is food production/ food security and water supply to climate change? • What is the adaptation capacity/options for communities in the Limpopo basin?
Basic Approach: • Establish past (20 years) and current status • Model future trends - 20 years - under climate change • Use findings from 1 and 2 determine vulnerability - discuss results with communities and other stakeholders. • Work out adaptation strategies and implementation schemes at different levels – includes active stakeholder participation. • Communicate results widely in the basin at national, regional and international level.
General objectives: • Establish past & present status of food (F) production, water (W) supply & demand in the Basin • Establish past & recent responses to climate variability in the F & W sectors. • Determine impacts of climate change (CC) on W & F using a range of IPCC based climate & national socio-economic scenarios. • Establish the level of vulnerability of Limpopo basin to CC on the F & W sectors • Determine indigenous adaptation capacity & mitigation options against adverse impacts • Contribute in increasing awareness to CC issues in southern Africa
Acquisition of relevant local scale data – A time consuming process • Climate data – in digital format & available within a short time - this is exceptional • For other data sets the situation is different – • Phane caterpiller- No production figures for such forest products - Phane export figures from Government’s Customs & Excise Dept. are aggregated with other exported different types of small protein sources. - Original Phane records are destroyed every 3 Yrs -lack of storage & computerisation. • Livestock Wildlife - locality statistics is lost -Aggregates over administration regions, not in digital form are kept -Problem of a basin study – the administrative regions usually overlap with other areas outside the basin.
Fire data - No system of archiving fire data although visual based fire reports are made every year. - Existingrecords are inconsistent, incomplete in terms of seasons or for a particular fire report & available for recent years - 1996-2001 - Areal extent and location of burn are only rough estimates.

Some progress • Water supply: Past climate, evaporation and soil data assembled and a stable research assistant secured. • SomeResults: Declining trend in annual rainfall over 28 years but no clear trend for runoff coefficient. • Water Demand: Hardcopy information converted to digital form. Resultsfrom one site: • Domestic sector - 50% of water demand & within this Private Connections takes over 70%
Phane Caterpiller –adaptation option for periods of crop failure
Phane caterpillar = Larvae of Imbrasia belina Westwood moth (Emperor Moth) (Lepidoptera: Saturniidae) Fig. 1 (Ditlhogo, 1996) **The reproduction cycle is sensitive to climate
Vulnerability and adaptation • Eco-tourism: An MSc students works on potential of ecotourism in the basin. • Results- The basin is rich in cultural heritage sites but these under utilized. - Flourishing tourism is wildlfe based -has limited direct benefit to local communities • Institutions & Policy: Msc student focusing on: Institutional and policy framework impact on vulnerability and adaptation capacity • Results-Most policies do not consider vulnerability to climate. - There are some short-term drought relief schemes implemented from time to time - Another MSc student - Sources of rural livelihoods - vulnerability and adaption to drought over time
Vulnerability and adaptation sections provide a gateway to access & involving stakeholder • Other links to stakeholders & National Communications: • Stakeholder meeting - June 2002 • AF42 – participated in 1st Meeting of the GEF/SGP on Climate Change Networking Group linked to the National Climate Change Committee (NCCC) • AF42 PI represents the University of Botswana (UB) at NCCC & also at the National Conservation Strategy Board • Research Permit – comments from Office of the Presidents • At a regional – information on AF42 disseminated via the Southern Africa Network – AF42 fire component
Constrains • Internet services • IT services • Institutional backing • Manpower resources
Next Focus of the study: • Determine impacts of climate change (CC) on Water & Food Climate & socio-economic scenarios. • Establish the level of vulnerability of Limpopo basin communities to CC on the Food & Water • Work out adaptation strategies & mitigation options against adverse impacts
