Target 1: Integrate the principles of sustainable development into country policies and programmes and reverse the loss of environmental resources.
Target 2: Halve, by 2015, the proportion of the people without sustainable access to safe drinking water and basic sanitation.
Target 3: By 2020, to have achieved a significant improvement in the lives of at least 100 million slum-dwellers.
Sustainable development can only be achieved with careful management of resources and ecosystems – but scientists warn that rates of land degradation are increasing and plant and animal species are being lost.
Urbanisation in developing countries has seen billions of people move to cities in search of better opportunities. However, many find themselves living in poor conditions in vast slums on the margins of urban areas.
Here they are likely to have little or no access to clean water or sanitation, increasing the incidence of preventable water-borne disease.
