Home gardening must shift from production fix to nutrition strategy – Prof. Marambe
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 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.

Govt. urged to halt ‘illegal’ presidential pardons
By Shamindra Ferdinando
The government is coming under pressure from civil society organisations to formulate a clear ‘mechanism’ to deal with requests for presidential pardons.
Representing civil society organisations, Gamini Viyangoda yesterday flayed the NPP government for the delay in taking action against Ven. Galagoda Aththe Gnanasara Thera, after the Supreme Court declared the 2019 presidential pardon granted to him by President Maithripala Sirisena null and void. He said successive Presidents had abused their executive power to release convicted persons from prison.
Purawesi Balaya activist Viyangoda pointed out that the Supreme Court ruled that President Sirisena had acted arbitrarily and failed to independently consider the relevant materials before exercising his executive power.
The Court of Appeal, in August 2018, sentenced Gnanasara Thera, General Secretary of the Bodu Bala Sena (BBS), to six years rigorous imprisonment for contempt of court over his conduct during proceedings concerning missing journalist Prageeth Ekneligoda. Viyangoda said that those who had been affected by the monk’s conduct have the right to know on what basis the President released him, in May 2019.
The Court of Appeal yesterday (05) ordered the relevant authorities to enforce the remaining period of imprisonment imposed on the Thera.
Gnanasara Thera, who had been subject to an open warrant for his arrest, was produced before the Court of Appeal, today, by prison officials.
Having considered the submissions made before it, the Court of Appeal directed the Commissioner General of Prisons to take the necessary steps to enforce the remaining period of the sentence imposed on Gnanasara Thera. Police on Saturday (03) apprehended the monk at a forest monastery in Kalutara. The Colombo Magistrate’s Court on Sunday (04) ordered the Thera to be remanded in custody till Monday.
Appearing for Gnanasara Thera, Attorney-at-Law Iresh Seneviratne, together with Attorney-at-Law Pasan Karunaratne, told the court yesterday that his client had been experiencing severe mental distress and had therefore gone to an ‘Aranya Senasanaya’, where he had been staying.
Viyangoda said that examination of presidential pardons, executed over the years, would reveal how successive leaders exploited the executive power to appease their own. Responding to The Island queries, Viyangoda said that Sirisena, in Sept. 2019, just two months before the presidential election, granted Jude Shramantha Jayamaha a Presidential pardon.
Jude Shramantha Jayamaha was sentenced to 12 years by the High Court, but the Court of Appeal revised that sentence to death, in July 2012, which the Supreme Court later upheld. Viyangoda said that though the Supreme Court, in June 2024, declared that the particular Presidential action was illegal and arbitrary, law enoforcement authorities were yet to take tangible measures to enforce the court directive.
Viyangoda stressed that no President should exercise the right to pardon a convicted on his or her own without following laid out procedures. According to him, Sirisena appeared to have simply ordered the monk, and the convicted murderer, released in response to appeals received by him. A comprehensive investigation could identify those who had been involved in these wrongdoings.

GL urges cautious handling of Saudi death row case, blasts govt. over BRICS affair
Convenor of Janathawadi Joint Opposition, Prof. G. L. Peiris, yesterday (05) emphasised the responsibility on the part of the government and others to act cautiously when making representations in respect of Sivarasa Anojan facing death sentence in Saudi Arabia over a controversial social media post.
Addressing the media at former President Ranil Wickremesinghe’s Flower Road Office, Prof. Peiris emphasised that whatever representations should be made through the Foreign Ministry.
The one-time External Affairs Minister warned of dire consequences of political party leaders, members of Parliament and civil society making direct representations and trying to get in touch with various Saudi authorities over the phone.
Prof. Peiris said that those who intervened on behalf of Anojan should keep in mind that Sri Lanka should be mindful of the Saudi way of governance and sensitivities.
The former Minister questioned the circumstances Sri Lanka was left out of the recent BRICS summit held in New Delhi. He recalled how former President Wickremesinghe discussed Sri Lanka’s entry into BRICS with Russian President Putin and received an invitation for the Summit there but as a result of the change of government, in Sept. 2024, Sri Lanka ignored that invitation.
That resulted in Sri Lanka being left out from the New Delhi summit, Prof. Peris said.
Prof. Peiris pointed out the absurdity in sending the Foreign Secretary to the BRICS Summit in Russia instead of the President, PM or the Foreign Minister to represent the country.
Referring to the forthcoming conclusion of the current IMF programme, initiated during Wickremesinghe’s time, Prof. Peiris said that Sri Lanka lost a great opportunity to benefit from BRICS by failing to represent the country at a higher level at the Russian summit.
The BRICS nations established the New Development Bank (NDB), originally called the BRICS Development Bank, Prof. Peiris said.
Dismissing NPP government’s explanation regarding Iranian ships awaiting necessary supplies but deprived by US imposed restrictions, the former Minister strongly criticised the administration’s response. According to him, this government responded in a similar manner when the US sank an unarmed Iranian frigate just outside Sri Lankan territorial waters in March this year.
Prof. Peiris declared that the government’s assertion that the US restrictions weren’t only directed at Sri Lanka but all Iranian vessels in other regions as well was not acceptable (SF)
