Declining Output Despite Privatization
Table of Contents
Sri Lanka’s natural rubber production dropped from 37,800 tons in 1990 to 24,300 tons in 2019, a decline of 13,500 tonssince rubber plantations were handed over to private management.
Most rubber-growing land in Sri Lanka is managed by 22 private plantation companies, which control the majority of the country’s estates.
Historical Background: From Colonial to Private Management
Rubber was first introduced to Sri Lanka in 1876 by Henry Wickham, who brought 1,700 seedlings to the island. The crop rapidly gained popularity, and by 1907, the total planted area had reached 65,000 hectares.
Smallholders (owning less than 20 hectares) now account for around two-thirds of the nation’s natural rubber output, while foreign-owned plantations once held about 35% of total acreage.
In 1970, all foreign-owned estates were nationalized, and management was transferred to the Janatha Estates Development Board (JEDB) and the State Plantations Corporation (SLSPC). However, after two decades of state control, both yield and area declined—production fell to 123 million kg and the cultivated area to 200,000 ha.
Yields were low due to reliance on the PB 86 clone, excessive rainfall disrupting tapping, low tree density, and outdated tapping systems.
Privatization and Restructuring in 1992
As part of economic liberalization, the Sri Lankan government leased out 22 plantation management companies in 1992, each holding 53-year leases (ending in 2045). The government retained a major shareholding, while private operators were expected to modernize production and improve efficiency.
Early performance reports from the World Bank–funded plantation restructuring project showed significant improvement in infrastructure and agricultural conditions. High-yielding clones, optimized fertilizer programs, and improved tapping systems were gradually introduced.
However, despite these reforms, output failed to recover to pre-privatization levels.
Key Performance Trends (1990–2019)
-
Total rubber area: Decreased by 23,110 ha (−1.4% annually)
-
Harvested area: Only 68.6% of total rubber area in 2019 (down from 1990 levels)
-
National rubber output: Fell from 37,800 tons (1990) to 24,300 tons (2019), an average decline of 1.2% per year
-
Yield: Decreased from 886 kg/ha/year to 830 kg/ha/year, or −0.2% annually
-
Replanting rate: Dropped by 10,000 ha between 1990 and 2019
This trend suggests that Sri Lanka’s national rubber output will continue to decline unless new replanting programs and processing facilities are introduced.
Processing Growth but Supply Shortfall
While Sri Lanka’s rubber processing industry has developed rapidly, domestic rubber production cannot meet demand. Manufacturers currently import around 60,000 tons of natural rubber annually, resulting in significant foreign exchange losses.
Boosting domestic production is thus essential to support the rubber goods industry and reduce dependence on imports.
Need for Policy and Management Reform
The performance of private-managed estates has not met expectations, even though private entities have access to modern technologies such as:
-
High-yielding clones,
-
Rain guards to minimize weather disruptions,
-
High-density planting techniques,
-
Low-frequency tapping systems to optimize labor productivity.
Some companies, however, have achieved positive results by implementing sound agronomic practices, reinvesting capital, and maintaining effective management structures.
To realize the goals of privatization, these successful models must be replicated across the sector. The government, as a key shareholder, must create an enabling environment for long-term investment, ensuring that the remaining 22 years of lease tenure do not hinder sustainability or reinvestment in Sri Lanka’s natural rubber industry.
