    • Improving peri­urban soils with re­cycled organic city waste: A case study from India Vincent Schmitt1, Priyanie Amerasinghe2, Dionys Forster3, Bharadwaja Vadloori2, Urs Niggli3Figure 1: Municipal wastedumped on the road side Background and rationale Hyderabads current urbanization rate is 4.7 %. This has resulted in benefits, but has also led to pollution problems associated with solid waste management. Urbanization has also impacted peri­urban agriculture, with land fragmentation and high production costs. This paper looks at opportunities for improved sanitation, entrepreneur development and soil enrichment for increasing agriculture productivity, by recyclingFigure 2: Promoter group the organic waste of city municipalities. Objective Results The aim of the study was to revitalise ­ In the municipality of Patancheru (GHMC), peri­urban agriculture soils with the organic fraction of the municipal waste is organic compost prepared from city estimated at 14280 kg per day.

Yet, in order to improve peri­urban soils, the final product has to be popularised, as the beneficial effects are not well known.
