Climate Change & Resilient Ecosystems Securing ecosystem services for human well-being E-parliament hearing, Mabula Lodge, South Africa 12-13 April 2008 What legislators can do for the sustainable use of THE DRYLANDS Dr. Juliane Zeidler, IECN, Namibia
What is special about drylands? • Naturally arid climates, prevailing droughts are normal • Water is scarce and often the limited factor for sustainable development o f drylands • Traditionally, people mainly live on livestock (pastoralists), game and some plants and fruits - relatively low impact • Agriculture depends heavily on water - drylands agriculture is seldom sustainable and requires high inputs • Biodiversity is uniquely adapted to the climatic and environmental conditions
Did you know …. • That drylands occupy approximately 50% of the Earth’s land surface around the world?(excl. the Arctic and certain Tundra areas) • That about 70% of the drylands worldwide are affected land degradation and loss of biodiversity? • That all drylands are faced with climate change impacts and have to adapt to them accordingly? • That more than 35% of the world’s population is living in drylands, many directly depending on natural resources and biodiversity for their daily survival – food, water & health? • That a majority of people living in drylands are living poverty?
A majority of people living in drylands are living in poverty: people’s development and ecosystem objectives need to be addressed together!
CC Risks and Impacts to be expected • Increase in temperature; reduced rainfall • Increased rainfall; increased temperature • Increased rainfall • More extreme events (droughts & floods) • Changes in growing season; ecosystem shifts
CCA action areas (a) Water resources (b) Food security and agriculture (c) Health (d) Disaster preparedness and risk management (e) Infrastructure (f) Natural resources management (g) Community level adaptation
Some case studies from Africa • Namibia: Wildlife as drylands compatible land use • Eritrea: Options for water usage and range development
A Growing Land Management Option: CBNRM & Wildlife • 50 Conservancies gazetted to date • ~118,276 km2 (13% of Namibia’s land mass) now falls within communal area conservancies • 212,000 people living in conservancies
Some key policy option areas • Community Empowerment and strengthening of adaptive capacities incl. Community-based Natural Resources Management (CBNRM) • Appropriate and compatible land uses • Safeguards: SEA/EIAs; feasibility assessments; “red flags” • Mainstreaming CC and drylands concerns into key national development policies; focus on adaptation • Reducing carbon emissions: SLM, sustainable energies and energy efficiency, watershed management and conservation
