1.0 Background to the project

This research is being conducted by the School of Public Policy, University of Birmingham, the Centre for Arid Zone Studies, University of Wales, Bangor, the University of Agricultural Sciences, Dharwad and S.D.M. College of Science and Technology, Dharwad, India.

The research commenced in January 1998 and aims to improve the utilisation of urban waste by near-urban farmers in the Hubli-Dharwad city-region of Karnataka, India. The research is particularly concerned with the problems associated with access to urban waste by small and marginal farmers, including transportation costs and the poor quality of the mixed municipal waste from the dumpsites in Hubli and Dharwad.

This is a summary of a recently completed Inception Report, which details the design of the research and some preliminary findings. The report outlines the current situation in the Hubli-Dharwad city-region regarding the management and use of urban waste, composting practices currently employed, a review of the use of urban waste in other city-regions of South Asia, a review of relevant soil fertility issues and sets out the research activities for the first six months of the research.

2.0 Use of urban waste

Urban waste has been utilised by farmers in the Hubli-Dharwad city-region for many years. The waste was purchased from the Hubli dumpsite by tractor loads and from the Dharwad dumpsite via an annual auction system managed by the Hubli-Dharwad Municipal Corporation (HDMC), selling waste by the pit load.

The sale and use of urban waste is declining as the waste is increasingly being contaminated by non-compostable waste, particularly plastics. However, there are several other factors which have affected the ability of the HDMC to sell the waste and the farmers' willingness to buy the waste. These include:

There are, however, some farmers who continue to purchase urban waste. These farmers are relatively wealthy, have their own tractors and are able to hire labour to transport and sometimes sort the waste. Small and marginal farmers do not presently have access to this potentially useful resource to use as a soil ameliorant.

In December 1997, the HDMC advertised for private sector companies to tender for waste disposal and treatment services. The preferred response intends to develop vermicomposting on a commercial basis in both Hubli and Dharwad. This will potentially continue to limit the access of urban waste by small and marginal farmers. HDMC, together with local NGOs, has also initiated trials of source separation and composting within a number of suburban localities within the two cities. The research project will seek to complement and build on the experiences of these trials.

3.0 Literature review

A brief review of literature regarding both solid waste and soil fertility issues is set out in the report. Key points arising from the literature reviews include:

4.0 Research activities in Phase 1

The report sets out the key research activities being undertaken during the first phase of the research, including analysis of waste, pilot composting trials and observation of farmers' activities and crop development during the kharif (rainy) season. A more extensive understanding of the generation, recovery and treatment of solid waste will be developed, particularly of the roles and interactions of the many stakeholders, including the Corporation, waste pickers, private sector contractors and farmers who have bought urban waste.

The observation of farmers is crucial in developing a more participatory approach to the research, thus generating:

It is intended that phase 1 of the research project will conclude at the end of September 1998, to enable a review of the research with a view to planning further stages with more detailed information and objectives.

5.0 Preliminary findings

A number of preliminary findings were derived from the inception visit and associated literature reviews. The key findings include:
