| Technique: |
INTEGRATED USE OF MARGINAL AREAS |
|
Definition characters description and diffusion
Forests and other marginal apparently non-productive areas, such as steppes and marshes, provide large quantities of food and water resources, and fodder and fertilizers for agriculture. They are also convenient to live in.
General characters description and diffusion
Calcutta's wetlands case is a good example within this framework. In the moist areas in the west of Calcutta, the traditional fishing and agricultural practices cover approximately 10,000 ha of the territory. Here the world's largest network of urban sewage water re-use takes place. Thousands of peasants convey millions of liters of sewage water from Calcutta towards their land. They consider these waters an advantageous nutrient supply and not as something harmful they should get rid of.
Advantages and sustainability
Otherwise discarded territories become very useful in the production of humus, food, and water collection in order to support populations of people.
