In fact, droughts and floods have increased in frequency, intensity and magnitude over the past two or three decades in the southern African region.

They have adversely impacted on food and water security, water quality, energy and sustainable livelihoods of the most rural communities. Currently, the majority of rural communities are experiencing chronic food deficits in many parts of the region on a year-round basis because of the effects of floods and droughts.

This increasing prevalence of recurrent floods and droughts has had far-reaching consequences for poor people in terms of food, water, health and energy in South Africa both in rural and urban areas.

The plight of the poor who dwell in informal settlements on the Cape Flats, near Cape Town, is, according to the government, "indeed a stark reminder of the fact that the world's poorest people are the most vulnerable to the increasingly frequent natural disasters such as flooding and droughts attributed to climate change."

Thus, climate change poses a serious threat to sustainable development in South Africa, largely due to the lack of capacity to manage the impacts of global climate change on the most vulnerable that sadly appear to constitute the vast majority of the South African population.

South Africa has acknowledged its role in the emission of greenhouse gases (GHGs) through its excessive dependence on coal. It has noted the immediate need for the country to move from being an energy-intensive economy to a low-carbon growth economy.

Current and proposed interventions on the ground for mitigating climate change have mainly focused on the energy sector due to the increasing realization that energy production is the primary and major route for GHG emissions in South Africa.

This has culminated in the formulation and adoption of various interventions, including the White Paper on the Renewable Energy Policy for South Africa, by the Department of Minerals and Energy, which aims to realize energy security through progressive switch from fossil fuels to renewable energy resources such as biomass, hydro, solar and wind.

The National Climate Change Response Strategy for South Africa does not only perceive energy-induced climate change as a threat to sustainable development, but also as an opportunity for realizing sustainable development, especially when activities for climate change mitigation are linked to poverty eradication and human capital development.

The collaborative approaches proposed for mitigating and/or managing the impacts of climate change in the National Climate Change Response Strategy for South Africa, reflecting such a perception in the government.

The investment opportunities created by the Clean Development Mechanism projects and the associated skills development initiatives and recruitment offers provided by these projects demonstrated the strategic opportunities that South Africa has for harnessing sustainable development through appropriate climate change interventions.

Having signed the convention, South Africa was obliged to fulfill certain commitments, including the launching of a Country Study Programme, which it did in 1997.

South Africa prepared an Initial National Communication on Climate Change in 2000, as required by Article 12 of the UNFCCC. Right now it is preparing its Second National Communication which is expected to be submitted by 2011.
