Ranaweera, Emeritus Professor, University of Sri Jayawardenapura and Dr Hiranya S. Jayawickrama Consultant Community Physician, Family Health Bureau.

The notion that home gardening can be treated as a blanket remedy for Sri Lanka’s deepening agricultural crisis is fundamentally misplaced, Senior Professor of Crop Science at the University of Peradeniya, Buddhi Marambe has warned.

Delivering the keynote address at the Science Forum on Food Security held at the National Science Foundation (NSF) on 29 April 2026, Prof. Marambe cautioned that while home gardens have an important role, they cannot substitute systemic solutions required to address structural weaknesses in the country’s food production sector.

Speaking at the forum, held under the theme, ‘Facing Agriculture Crisis – Home Gardening as a Tool’, Prof. Marambe said Sri Lanka’s food security challenges were increasingly shaped by shrinking agricultural land per capita, climate volatility and rising input costs.

He noted that global agricultural land per person had fallen sharply from about 1.45 hectares in 1961 to 0.6 hectares in 2023, while in Asia it had declined to 0.35 hectares. In Sri Lanka, he said, the figure had dropped further from 0.17 hectares to just 0.13 hectares over the same period, underscoring severe land constraints.

Against this backdrop, Prof Marambe said home gardening could not be expected to compensate for the loss of large-scale production systems such as paddy cultivation, which depended on wetlands that could not be replicated in residential spaces.

He also pointed to the growing impact of extreme weather events, citing Cyclone Ditwah (2025), which brought record 24-hour rainfall of 375 mm in parts of the country and caused extensive damage to paddy and other field crops. Climate-related losses in paddy production were estimated at 35.4 per cent, with policy-related disruptions accounting for a further 34.1 per cent.

Several districts, including Anuradhapura, Polonnaruwa and Batticaloa, recorded damage to over 20,000 hectares of cultivated land, he noted, warning that such shocks are becoming more frequent and unpredictable.

Prof. Marambe speaking at the science forum

Prof. Marambe highlighted economic pressures on agriculture, particularly the volatility in fertiliser prices. Citing global market data, he said urea prices had peaked at nearly USD 750 per tonne in early 2026 before easing marginally, placing additional strain on farmers.

Referring to the COVID-19 pandemic experience, he cautioned against unstructured promotion of home gardening, noting that during lockdowns many households had turned to cultivating crops such as ginger and turmeric, eventually leading to market gluts that disrupted livelihoods of commercial producers.

“Different crises require different solutions,” he said, arguing that home gardening should not be seen as a universal production substitute but rather as a targeted intervention.

He stressed that the most practical and sustainable role of home gardening lay in addressing household nutrition rather than bulk food production. At a time when rising food prices were contributing to nutritional decline, he said, home gardens should be reoriented towards improving dietary diversity.

“Even small-scale interventions such as keeping a few hens for eggs to obtain daily protein requirement or cultivating leafy vegetables in limited space can significantly strengthen household nutrition security,” he said.

Prof. Marambe advocated a shift towards “nutrition-focused home gardening”, integrating crops and small livestock within urban and rural homesteads. He also pointed to successful models of urban farming, community gardens in Colombo flats, and school gardening initiatives supported by development partners.

He said such systems, if properly structured, could play a meaningful role in cushioning vulnerable populations against food price shocks while improving dietary outcomes.

However, he reiterated that home gardening must be viewed as one component within a broader agricultural strategy rather than a standalone solution to Sri Lanka’s food security challenges.

The forum, organised by the Media and Event Management Division of NSF under the purview of the Ministry of Science and Technology, brought together leading experts in food science including Emeritus Professor K. K. D. S. Ranaweera, Prof. Renuka Silva and Dr Hiranya Jayawickrema, alongside representatives from print, electronic and social media.

Renewable energy producers left high and dry as CEB prioritises spending on oil-fired power plants

Published

Sri Lanka could face a serious electricity supply crisis if outstanding payments owed to renewable energy producers are not settled urgently, industry representatives have warned.

According to renewable energy sector sources, the National System Operator (Private) Company has not paid more than Rs. 10 billion due to renewable power producers for electricity supplied to the national grid between December 2025 and April 2026.

The Federation of Renewable Energy Developers said the prolonged delay in payments had placed severe financial strain on producers and threatened the continued supply of renewable power to the national system.

Speaking to The Island, Federation Vice President Prabath Wickramasinghe said the payment crisis had emerged as authorities prioritised expenditure on diesel and furnace oil generation to offset a daily electricity shortfall of nearly 150 megawatts caused by inefficiencies in coal power generation.

He said the escalating conflict in the Middle East had sharply increased global fuel prices, resulting in a steep rise in thermal power generation costs, estimated at close to or above Rs. 10 per unit.

“In this situation, greater focus on renewable energy has become essential,” Wickramasinghe said.

He noted that the issue affected not only large-scale renewable projects but also ground-mounted solar power plants, mini-hydropower projects, wind farms and biomass power stations operating across the country. According to the Federation, 389 renewable energy plants with a combined installed capacity of 1,073.9 megawatts were currently affected.

Wickramasinghe warned that continued non-payment could lead to plant owners defaulting on bank loans and other financial obligations, while also undermining investor confidence and destabilizing the renewable energy sector.

He further cautioned that the crisis could ultimately contribute to future electricity shortages if renewable energy suppliers reduce or suspend generation.

When contacted by The Island, Chairman of the National System Operator (Private) Company Dr. B.L. Pradeep Priyadarshana Perera acknowledged delays in payments and said discussions were underway with the Ministry of Finance to resolve the issue promptly.

PM Amarasuriya

Prime Minister Dr. Harini Amarasuriya told Parliament on Wednesday that the government was planning to reform the higher education sector in line with the ongoing transformation of the primary and secondary education systems.

Responding to questions raised by Digamadulla District NPP MP Manjula Sugath Rathnayaka, the Prime Minister said a special expert committee appointed to review the higher education sector had been functioning over the past six months and was expected to submit recommendations aimed at addressing long-standing structural and administrative issues.

“A special expert committee appointed for this purpose has been in operation over the past six months, and based on the report of this panel, existing issues in the higher education sector will be identified and the necessary reforms will be implemented,” she said.

Providing details on university admissions, Dr. Amarasuriya said 281,810 students had sat the 2025 GCE A/L Examination, and out of them 176,538 were qualified for university admission. However, only 42,937 students could gain admission to state universities.

The Prime Minister said the highest number of qualified students was from the Arts stream (58,269) candidates, followed by Commerce stream (39,608), Biological Sciences (32,935), and Physical Sciences (23,012). In addition, 12,472 students were qualified in the Engineering Technology

stream, 6,043 in the Bio-Systems Technology, and 4,199 in the General Stream.
