The study was confined to the 3 major rubber growing districts of Sri Lanka, namely; Kegalle, Kalutara and Ratnapura districts. The methodologies involved in this study were Participatory Rural Appraisal (PRA) and questionnaire surveys. Substandard growth in immature lands, low productivity in mature lands, low quality in produced rubber, low societal involvement and improper marketing were identified as major issues at local and regional level while depletion of the rubber extent was of national concern. Appropriate institutional responses to combat adverse impacts of these issues are also discussed to improve the well being of rubber smallholders and the country as a whole.

The total land area under smallholder sector provides a share of rubber is 115,992 ha which accounts for about 33% to the national rubber about 8% of the total cultivated extent production.
