Sustainable solution to decline in tea production
Mr. Jayampathy Molligoda, (JM) Chairman, Sri Lanka Tea Board, in his article on a Sustainable solution to decline in tea production, export revenue and livelihood issues, in The Island of 17 May, concludes that there has been a gradual decline in tea productivity measured in terms of the yield per hectare in Sri Lankan tea estates, partly due to continuous application of chemical fertilizer.
It is correct that there is a gradual decline in the productivity of tea lands during the last few years. But, Mr. JM assumes that the decline in tea production is due to continuous application of chemical fertilizer. This assumption cannot be correct, as the Tea Research Institute (TRI) by the advisory circular SP 10 issued in August 2016, recommends application of mixed fertilizer containing nitrogen, phosphorus and potassium as urea, Eppawala Rock Phosphate and muriate of potash respectively, for mature tea fields in 2 to 5 splits per annum. This recommendation must be based on field trials conducted by research staff of the TRI. If the Chairman, Sri Lanka Tea Board assumes that continuous application of chemical fertilizer causes a decline in productivity, it is difficult to understand the above recommendation of the TRI.
Application of inorganic fertilizer is essential for growth of plants. This is adequately highlighted in the publication titled ” Effects of Fertilizers on Tea Yields and Quality: A Review with Special Reference to Africa and Sri Lanka by Okinda Owuorl, Principal Scientist, Tea Research Foundation of Kenya. Ref. https://repository.up.ac.za/bitstream/handle/2263/8222/Owuor_2001.pdf?sequence=1
The average tea yields of Sri Lanka are considerably lower than the potential yields. It has been reported that some of the cultivars developed by the TRI had been yielding around 8,000 kg/ha in South India under commercial conditions.. However, the average tea yield in Sri Lanka is much lower. Productivity of tea lands indicated by kg/ha/year has fluctuated around 1,600. In fact it has decreased from 1,736 kg/ha in 2014 to 1,602 kg/ha 2017, possibly due to undesirable weather, soil erosion leading to infertile soils, pests and diseases, etc. A study of the agricultural profile of the Corporate Tea sector was carried out a few years by the TRI. According to the findings of this study, the productivity of tea estates indicated by kg/ha/year, was less than 1500 in 183 estates. It is necessary that the RPCs implement an effective programme to increase the productivity of those estates giving low yields, after a detailed study to determine the reasons for the low yields so that appropriate action could be taken. Low per hectare yields could be due to a number of factors, such as soil degradation, old age of the crop, water shortage, etc
Soil degradation
Soil degradation in tea lands is mainly due to soil erosion, soil compaction, nutrition depletion, and loss of biodiversity, etc. According to a paper presented by Dr. M.A. Wijeratna of the TRI, at the first national symposium on Land Degradation held a few years ago, the loss of topsoil due to water erosion in the mid and up country tea lands could be in the range of 30-50cm, and this alone has been responsible for reduction of land productivity of tea by around 30-50%. If productivity of tea lands is to be sustained, it is essential that appropriate measures are taken to reduce soil degradation.
In view of the importance of soil degradation, the Ministry of Environment, in 2005, established an expert committee on Land Degradation. This committee comprised a number of experts in the field of land management, and its main role was to advise the Ministry of Environment, on issues related to controlling land degradation. This committee has not met since Feb. 2013. There are many ministries, departments and other institutions such as the TRI, which are expected to take appropriate measures to control land degradation. During the last few years a large number of seminars, workshops have been held on this topic. In spite of all these, land degradation continues to take place, evident by the common occurrence of landslides, depleted topsoil, siltation of tanks and reservoirs, decline in crop yields, etc. The Ministry of Environment (ME) needs to activate the already established Committee on Land Degradation, which would make appropriate recommendations to reduce land degradation to be implemented by the ME and other organizations. A land use policy has been formulated, but is not effectively implemented to reduce land degradation, which has serious repercussions on productivity. The land use policy needs to be implemented as an integrated programme in increasing the productivity of the tea sector.
Age of crops
A considerable part of the tea crop is old. For example, about 40% of the tea extent is under seedling tea and about 90% of the seedling teas are over 60 years old, and need replanting. Around 30% of the VP tea is more than 30 years old, and these also need replanting. According to the Ministry of Plantation Crops, during 2010-2012 the average annual replanting in the corporate tea sector was 1.1% , in the smallholder sector it was 0.7%. and the national average is 0.9%. Ideally this should be around 2%. If productivity of tea lands is to be sustained, it is essential that a replanting programme is implemented during the coming years.
Water Management
Rainfall variability is an inherent challenge for farming in tropical and sub-tropical agricultural systems. The variable rainfall also results in poor crop water availability, reducing yields to 25-50% of potential yields. Sri Lanka has been experiencing frequent droughts and floods over the last few years. Climate change prediction studies have indicated that Sri Lanka will experience high variability of rainfall. Some areas will get more rain during some months, and during the rest of the year the soil will be dry, affecting the crop. The simple solution in this case, is to increase the retention of water that is received during the rainy periods to be used during the dry periods. Around 40-60% of the amount of the rain that falls on land is lost due to run off, and only the balance of the total rainfall is infiltrated into the soil profile. Hence, harvesting the rainfall as much as possible would increase the availability of water in the soil, which will sustain the productivity of crops. The water retained by the soil profile is related to its depth, structure and also its organic matter (O.M) content. Hence strategies to increase soil depth and O.M levels would greatly enhance the water retention capacity, thereby increasing RW harvesting. If productivity of tea lands is to be sustained, it is essential that an effective water management programme is implemented in all the tea estates.
A Database on plantation sector
A complete and updated database on the corporate tea sector would be extremely useful in the endeavours to increase the productivity of this sector. Such a database will be of much use in planning, making policy decisions and management practices, such as replanting, diversification and identifying the development needs of the plantation sector; and would enable the relevant authorities to channel investments to sustain productivity of the sector.
The proposed database would mainly include data related to Land Use ( extent of uncultivated land, extent under forest and different crops, extent under nurseries) total annual production, YPH during the last five years, age categories of the crop, extent replanted during the last five years, source of water and degree of soil degradation etc. for each estate. I hope that the Chairman, Sri Lanka Tea Board will get the RPCs to develop an appropriate database, which will be extremely useful in sustaining tea yields.

Missing 52%: Why Women are absent from Pettah’s business landscape
Walking through Pettah market in Colombo, I have noticed something both obvious and troubling. Shop after shop sells bags, shoes, electronics, even sarees, and yet all shops are owned and run by men. Even businesses catering exclusively to women, like jewelry stores and bridal boutiques, have men behind the counter. This is not just my observation but it’s a reality where most Sri Lankans have observed as normal. What makes this observation more important is when we examine the demographics where women population constitute approximately 52% of Sri Lanka’s population, but their representation as business owners remains significantly low. According to the Global Entrepreneurship Monitor 2023 report, Sri Lanka’s Total Early Stage Entrepreneurial Activity rate for women is just 8.2%, compared to 14.7% for men.
Despite of being the majority, women are clearly underrepresented in the entrepreneurial aspect. This mismatch between population size and economic participation create a question that why aren’t more women starting ventures? The answer is not about capability or intelligence. Rather, it’s deeply in social and cultural barriers that have been shaping women’s mindsets for generations. From childhood, many Sri Lankan girls are raised to believe that their primary role is as homemakers.
In families, schools, and even universities, the message has been same or slightly different, woman’s success is measured by how well she manages a household, not by her ability to generate income or lead a business. Financial independence is rarely taught as essential for women the way it has been for men. Over time, this messaging gets internalised. Many women grew up without ever being encouraged to think seriously about ownership, leadership, or earning their own money. These cultural influences eventually manifest as psychological barriers as well.
Years of conditioning have led many skilled women to develop what researchers call “imposter syndrome”, a persistent fear of failure and feel that they don’t deserve success kind of feeling. Even when they have the right skills and resources, self-doubt holds them back. They question whether they can run a business independently or not. Whether they will be taken seriously, whether they are making the right choice. This does not mean that women should leave their families or reject traditional roles. But lack of thinking in a confident way and make bold decisions has real consequences. Many talented women either never start a business or limit themselves to small, informal ventures that barely survive. This is not about men versus women. It’s about the economic cost of underutilising 52% of the population. If our country is genuinely serious about sustainable growth. we must build an inclusive entrepreneurial ecosystem through confidence building programs, better finance access to women, and a long term societal mindset shift. Until a young girl walking through Pettah can see herself as a future shop owner rather than just a customer, we will continue to waste our country’s greatest untapped resource.

Molten Salt Reactors
Some essential points made to indicate its future in Power Generation
The hard facts are that:
1) Coal supplies cannot last for more than 70- 100 years more at most, with the price rising as demand exceeds supply.
2) Reactor grade Uranium is in short supply, also with the price rising. The cost is comparable to burning platinum as a fuel.
3) 440 standard Uranium reactors around the world are 25-30 years old – coming to the end of their working life and need to be replaced.
4) Climate Change is increasingly making itself felt and forecasts can only be for continuing deterioration due to existing levels of CO2 being continuously added to the atmosphere. It is important to mention the more serious problems associated with the release of methane gases – a more harmful gas than CO2 – arising from several sources.
5) Air pollution (ash, chemicals, etc.) of the atmosphere by coal-fired plants is highly dangerous for human health and should be eliminated for very good health reasons. Pollution created by India travels to Sri Lankans by the NE monsoon causing widespread lung irritations and Chinese pollution travels all around the world and affects everybody.
6) Many (thousands) of new sources of electric power generation need to be built to meet increasing demand. But the waste Plutonium 239 (the Satan Stuff) material has also to be moved around each country by lorry with police escort at each stage, as it is recovered, stored, processed and formed into blocks for long term storage. The problem of security of transport for Plutonium at each stage to prevent theft becomes an impossible nightmare.
The positive strengths to Thorium Power generation are:
1) Thorium is quite abundant on the planet – 100 times more than Uranium 238, therefore supplies will last thousands of years.
2) Cleaning or refining the Thorium is not a difficult process.
3) It is not highly radioactive having a very slow rate of isotope decay. There is little danger from radiation poisoning. It can be safely stored in the open, unaffected by rain. It is not harmful when ingested.
4) The processes involved with power generation are quite different and are a lot less complex.
5) Power units can be quite small, the size of a modern detached house. One of these can be located close to each town, thus eliminating high voltage cross-country transmission lines with their huge power losses (up to 20%).
6) Thorium is ‘fertile’ not fissile: therefore, the energy cycle has to be kick-started by a source of Neutrons, e.g., fissile material, to get it started. It is definitely not as dangerous as Uranium.
7) It is “Fail – Safe”. It has walk-away safety. If the reactor overheats, cooled drain plugs unfreeze and the liquid drains away to storage tanks below. There can be no “Chernobyl/ Fukoshima” type disasters.
8) It is not a pressurized system; it works at atmospheric pressure.
9) As long as reactor temperatures are kept around 600 oC there are little effects of corrosion in the Hastalloy metal tanks, vessels and pipe work. China, it appears, has overcome the corrosion problem at high temperatures.
10) At no stage in the whole chain of operations is there an opportunity for material to be stolen and converted and used as a weapon. The waste products have a half- life of 300 years, not the millions of years for Plutonium.
11) Production of MEDICAL ISOTOPE Bismuth 213 is available to be isolated and used to fight cancer. The nastiest cancers canbe cured with this Bismuth 213 as Targetted Alpha therapy.
12) A hydrogen generation unit can be added.

Foreign degrees and UGC
There are three key issues regarding foreign degrees:
Recognition: Is the awarding university recognized by our UGC?
Authenticity: Is the degree genuine or bogus?
Quality: Is it a standard, credible qualification?
1. The Recognition Issue (UGC Role)
The UGC addresses the first issue. If a foreign university is listed in the Commonwealth Universities Yearbook or the International Handbook of Universities, the UGC issues a letter confirming that the university is recognized. However, it is crucial to understand that a recognized university does not automatically imply that every degree it issues is recognized.
2. The Authenticity Issue (Employer Role)
The second issue rests with the employer. It is the employer’s responsibility to send a copy of the foreign degree to the issuing university to get it authenticated. This is a straightforward verification process.
3. The Quality Assurance Gap
The third issue
—the standard and quality of the degree—has become a matter for no one. The UGC only certifies whether a foreign university is recognized; they do not assess the quality of the degree itself.
This creates a serious loophole. For example:
Does a one-year “top-up” degree meet standard criteria?
Is a degree obtained completely online considered equivalent?
Should we recognize institutions with weak invigilation, allowing students to cheat?
What about curricula that are heavy on “notional hours” but light on functional, practical knowledge?
What if the medium of instruction is English, but the graduates have no functional English proficiency?
Members of the UGC need to seriously rethink this approach. A rubber-stamp certification of a foreign university is insufficient. The current system ignores the need for strict quality assurance. When looking at the origins of some of these foreign institutions (Campuchia, Cambodia, Costa Rica, Sudan..) the intentions behind these “academic” offerings become very clear. Quality assurance is urgently needed. Foreign universities offering substandard degrees can be delisted.
