Climate-Smart Agriculture: Best path forward for South Asia and Sub-Saharan Africa, study finds
A new study highlights Climate-Smart Agriculture (CSA) as the most effective approach to address the intertwined challenges of climate change, food security, and rural development in South Asia and Sub-Saharan Africa.
The study released on Sunday said that by focusing on sustainably increasing agricultural productivity, enhancing resilience to climate change, and reducing greenhouse gas emissions, CSA emerges as a transformative solution for two of the world’s most climate-vulnerable regions. With growing commitments from national governments and international non-profit organizations to invest in CSA, these regions stand to benefit significantly from financial and technical resources that support sustainable agricultural practices and climate adaptation.
The study, titled ‘The Role of Digital and Climate-Smart Agriculture in Climate Change Mitigation: A Systematic Mapping Protocol’ aims to explore the potential of digital agriculture technologies in achieving climate change mitigation, while balancing food security and on-farm adaptation in South Asia and Sub-Saharan Africa. The report, authored by Maaz Gardezi, Xinjing Yu, Pablo Carcamo, and Sheetal Kumari, highlights the need for evidence-based strategies to maximize the benefits of these technologies for smallholders in vulnerable regions.
Climate-Smart Agriculture (CSA) is recognized as a global policy priority due to its potential to address climate change while ensuring food security. Recent advancements in digital agriculture technologies, such as precision agriculture and data analytics, are helping implement CSA practices. However, the study notes a significant knowledge gap regarding how these innovations can support small-scale farmers in achieving climate mitigation goals without compromising their food security or adaptation efforts.
The lack of clarity on the scope, drivers, barriers, and on-farm impacts of digital CSA, poses a challenge for policymakers in designing strategies to address its potential risks and benefits effectively.
The study outlines a methodology to create a systematic map that compiles evidence on the evolution and impacts of digital Climate-Smart Agriculture in South Asia and Sub-Saharan Africa. It will employ two search strategies: Systematic bibliographic search to gather relevant literature and Citation chase approach to trace interconnected studies.
Articles will be selected based on a pre-defined framework aligned with the Population, Intervention, and Outcome (PIO) model. The systematic map will identify knowledge gaps and clusters, presenting findings through narrative synthesis, an evidence atlas, and visualizations.
By synthesizing evidence, this research seeks to inform policymakers about the role of digital agriculture in climate change mitigation, helping them develop strategies that maximize benefits while minimizing risks. It also aims to address critical gaps in understanding how smallholders can adopt these technologies to improve resilience and reduce greenhouse gas emissions.
The study underscores the need for targeted interventions in South Asia and Sub-Saharan Africa, where climate change poses severe risks to agriculture and livelihoods, particularly for small-scale farmers. The findings are expected to provide a roadmap for integrating digital innovations into climate-smart agricultural policies and practices.
The report has been published by the CGIAR, a global research partnership for a food-secure future. CGIAR science is dedicated to transforming food, land, and water systems in a climate crisis. Its research is carried out by 13 CGIAR Centers/Alliances in close collaboration with hundreds of partners, including national and regional research institutes, civil society organizations, academia, development organizations and the private sector.

SJB asks Prez not to reduce MR’s security for criticising govt.
The SJB yesterday urged the government to reconsider its decision to scale back the security provided to former President Mahinda Rajapaksa.
Addressing a press conference at the SJB Headquarters, Colombo District MP Mujibur Rahuman criticized President Anura Dissanayake for his recent remarks suggesting that Rajapaksa’s security could be withdrawn if he became increasingly critical of the government.
“Such a statement is unbecoming of a President. The President claimed that security arrangements for former Presidents and MPs would be based on intelligence reports. However, his comments about Mahinda Rajapaksa suggest that no such intelligence report was taken into consideration,” Rahuman said.
He accused President Dissanayake and his Ministers of continuing to act as if they were in the Opposition rather than leading the government. “It seems that President Dissanayake has forgotten that he is now the President of the country. Similarly, the Ministers in the government seem to have forgotten that they are part of the government. There is no difference between the speeches the President made during his time in the Opposition and the ones he makes now. It is hard to discern whether the person speaking is the President or the former Opposition MP,” Rahuman said.
Rahuman emphasised that the President must now focus on governance and prioritise the safety of the general public. He highlighted the recent spate of gun violence across the country, noting that eight people had been killed in shooting incidents in January alone. “Ensuring the safety of the general public remains an unachieved goal of this government,” he said.

Natural disasters affect 17,000 in 11 districts
Most reservoirs are overflowing causing widespread flooding
Close to 17,000 people have been adversely impacted by natural disasters, triggered by heavy rains across Sri Lanka, the Disaster Management Centre (DMC) reported on Monday morning. A total of 16,930 individuals from 5,738 families, in 11 districts, have been affected, with one death and three injuries recorded. The Meteorology Department has forecast thundershowers in several provinces, while landslide and flood warnings issued on Sunday remain in effect for the next 24 hours.
The North-East monsoon has unleashed heavy rains across the country’s East, North Central, and Eastern slopes of the central hills, causing widespread flooding, reservoir spills, and disruptions. More than 50 major tanks and reservoirs are overflowing, inundating downstream towns and agricultural areas, according to the Irrigation Department and Disaster Management Centre (DMC).
Four major reservoirs in the north—Iranamadu Reservoir (Kilinochchi), Pavakkulam Reservoir (Vavuniya), Vavunikulam Reservoir (Mullaitivu), and Muthaiyankattu Reservoir—have fully opened their spill gates. Water flowing through medium and small reservoirs has damaged paddy fields for the third time this season and submerged several key roads, disrupting transportation and daily activities.
Director of Irrigation (Water Management) H.F.P.S.D. Herath reported that 54 out of 73 major reservoirs, controlled by the Department, are overflowing. Additionally, 43 mid-sized reservoirs have reached their discharge limits, with 93% of total reservoir capacities currently retained. The Rajanganaya reservoir is overflowing at a rate of 17,000 cubic feet per second, while the Deduru Oya reservoir is spilling at 16,000 cubic feet per second, raising flood risks in multiple areas.
Herath said that the low-lying areas in the Kala Oya valley, Deduru Oya valley, and Gal Oya region face imminent flood threats. Roads in areas, such as Batticaloa-Polonnaruwa, Malwatu Oya, and Nachchaduwa, have been inundated, making crossings dangerous. Flood warnings have been issued for Vengalacheddikulam, Madu, Mussalei, and Nanaddan DS divisions.
Residents in vulnerable areas, including Wariyapola, Chilaw, Akkareipattu, and Karuwalagaswewa, have been urged to remain vigilant, he said.
Schools in the North Central Province have been closed, according to Education Director S.M.W. Samarakoon, as a precautionary measure. Traffic on the Batticaloa-Polonnaruwa main road has also been suspended due to the rising water level in the Mahaweli River.
The Department of Meteorology reported reduced rainfall in parts of the island on Monday but warned of continued rains in the Northern, North Central, Eastern, Uva, and Central provinces. Cloudy skies and temporary localized strong winds, with lightning during thunderstorms ,remain a concern.
Residents and vehicle drivers in affected areas are requested to take precautions, while disaster management authorities have been instructed to take proactive measures.
As conditions remain volatile, authorities are monitoring the situation closely and responding to emerging challenges.
A navy boat reaches to people affected by severe whether conditions at Buddhangala in Padvaiya. Navy relief teams deployed in affected areas, equipped with dinghies, facilitated transportation and extended essential support to communities, enabling them to carry out their daily activities. Additionally, 49 Navy relief teams are ready and on alert to be deployed immediately to provide assistance to the public in case of flooding, the Navy said.
