Impact of Climate Change Additional people with Increased water stress (5 0 C) 20 to 30% species at inc. high risk of extinction (2-3 0 C) Decrease (low latitudes) (1-2 0 C) Increase (mid & high latitudes) (1-2 0 C) (impact is beneficial) 30% loss of coastal wetlands (3-4 0 C) Increased mortality due to heatwaves, floods and drought ( 1 0 C) Reconfiguration of coastlines and inundation of low-lying areas (5 0 C)

Climate Change and other development issues

Climate Change and its linkages with Sustainable Development

SD and Climate Change Sustainable Climate � Alternative development pathways Climate � Sectoral environment/ economic policies development change � Institutional/managerial changes change policies policies � Innovation/ technological change Sustainable � Avoided climate change damage � Ancillary benefits/costs development � Spillovers/trade effects � Innovation/technological change Two-way linkages between climate change and sustainable development. Source: Swart et.al (2003)

Efforts to cope with the impacts of climate change and attempts to promote sustainable development share common goals and determinants • Access to resources • Equity in the distribution of resources (i.e. human and social capital) • Access to risk-sharing mechanisms • Abilities of decision- support mechanisms to cope with uncertainty

Nonetheless, some development activities exacerbate climate-related vulnerabilities High rise building in Processing urban areas plants Road Land use change/Mining development in natural forests (Irresponsible mining)

Climate change will result in net costs into the future; these costs will grow over time By 2080, it is likely that : 1.1 to 3.2 billion people will be experiencing water scarcity 200 to 600 million will be hungry 2 to 7 million more per year affected by coastal flooding

Climate change will impede nations’ abilities to achieve sustainable development pathways as measured, for example, by long-term progress towards the Millennium Development Goals
