URBAN AGRICULTURE AS A TOOL FOR SUSTAINABLE
MDG 7 calls for 'ensuring environmental sustainability', particularly through integrating
principles of sustainable development into policies and programmes, reversing the loss of
environmental resources, and significantly improving the lives of at least 100 million
slum dwellers (improved sanitation and secure tenure). Lack of access to improved
sanitation is more severe in the crowded cities of South and East Asia but progress in
sub-Saharan Africa was stalled in the 1990s.
Because UA links cities and their environment, it can be an increasingly acceptable,
affordable and effective tool for sustainable urbanization (Deelstra and Girardet, 1999).
Poor sanitation, unsafe water supply, uncollected garbage and polluted rivers, all create
environmental health hazards, reduce living standards, increase costs, reduce productivity
and inhibit socio-economic development. The production of trees, shrubs, flowers and
ornamental plants and food crops can beautify the city, cool its climate, curb erosion and
