Although many irrigation systems in the dry zone of Sri Lanka have water shortage problems, water consumption is very high during land preparation. This paper analyzes the impact of institutional interventions on efficient water management, especially during the land preparation period. It provides a comprehensive understanding of the factors behind prolonged periods of land preparation so that system managers and farmers communities can develop appropriate interventions to reduce water consumption

The global prevalence of chronic kidney disease (CKD) of uncertain etiology may be underreported. Communitylevel epidemiological studies are few due to the lack of national registries and poor focus on the reporting of noncommunicable diseases. Here we describe the prevalence of proteinuric-CKD and disease characteristics of three rural populations in the North Central, Central, and Southern Provinces of Sri Lanka. Patients were selected using the random cluster sampling method and those older than 19 years of age were screened for persistent dipstick proteinuria. The prevalence of proteinuric-CKD in the Medawachchiya region (North Central) was 130 of 2600 patients, 68 of 709 patients in the Yatinuwara region (Central), and 66 of 2844 patients in the Hambantota region (Southern). The mean ages of these patients with CKD ranged from 44 to 52 years. Diabetes and long-standing hypertension were the main risk factors of CKD in the Yatinuwara and Hambantota regions. Age, exceeding 60 years, and farming were strongly associated with proteinuric-CKD in the Medawachchiya region; however, major risk factors were uncertain in 87% of these patients. Of these patients, 26 underwent renal biopsy; histology indicated tubulointerstitial disease. Thus, proteinuric-CKD of uncertain etiology is prevalent in the North Central Province of Sri Lanka. In contrast, known risk factors were associated with CKD in the Central and Southern Provinces.

Agricultural practices are changing at an unprecedented rate in small pockets of the dry zone of Sri Lanka. Commercial vegetable production is flourishing underwritten by groundwater accessed via agro-wells, increased market access and new business opportunities. Since the early 1990s, small-holder farmers have been excavating agro-wells for highland field irrigation and reaping unprecedented returns. Highland fields were previously subject to rain-fed shifting cultivation with long fallow periods. Water from agro-wells with the addition of chemical inputs, along with the advent of mobile phones, reliable road transport, new markets, greater access to credit and a more secure post-conflict environment, have now made frequent highland cropping viable and profitable. This has ignited the entrepreneurial spirit of farmers whose financial inputs and investments and labour is bringing rapid socio-economic transformation. In a country where the dry zone constitutes roughly a third of the land area, and where many dry zone households lack surface water for dry season cropping, these pockets of groundwater driven dry season production may pose a way out of poverty. While acknowledging the significant impact of agro-well-based farming in lifting farmers out of poverty, the paper ends on a cautionary note. This type of agricultural intensification is predicated on a social-ecological system linked to a specific institutional architecture and an aquifer with highly variable water availability. Current success in poverty alleviation masks an inherent fragility and risk that warrants further investigation before attempts are made to scale out groundwater based dry season farming to other parts of the dry zone.

This paper assesses how the Huruluwewa tank (HWT) irrigation system in the North Central Province of Sri Lanka adapts to climate variability. The lessons learned in the HWT will be helpful for many water-scarce irrigation systems in the country, which bear high climate risks. Recurrent droughts are the bane of agriculture in the Dry Zone, comprising three-fourths of the land area spread over the Northern, North Central and Eastern provinces. In the HWT, the fifteenth largest canal irrigation system in the country, adaptation to climate variability happens on several fronts: changes made by the irrigation management to the water release regime; changes in the cropping patterns practiced by farmers in the command area; and the use of groundwater, which is recharged from rainfall, reservoir storage and canal irrigation, as supplemental irrigation. Such adaptation measures ensure that the available water supply in the reservoir is adequate for 100% cropping intensity over two cropping seasons, even in drought years, and enhances economic water productivity in terms of value per unit of consumptive water use. Moreover, irrigation management should consider groundwater recharge through canal irrigation as a resource, which brings substantial agricultural and economic benefits not only for the command area but also outside the command area. The adaptation patterns implemented in HWT demonstrate how water-scarce irrigation systems can achieve higher economic water productivity, i.e., generate ‘more income per drop’ to enhance climate resilience for people in and outside the canal command areas.

Drought is an almost annual phenomenon in Sri Lanka, occurring at varying degrees of severity and affecting many parts of the country. These droughts cause significant damage to agriculture and other economic and social activities. This paper assesses the effectiveness of satellite-based weather Index insurance (WII) bundled with real-time climate and agronomic advisory services provided to farmers’ mobile phones. The aim is to enhance the drought resilience of diverse groups of farmers by providing solutions and strategies to extend bundled insurance products to more people and address equity issues.
In this pilot, an insurance product was introduced to farmers in a village in the North Central Dry Zone of Sri Lanka. WII products are seen as a part of the solution to reducing farmers’ risk to climate change. However, in many places, the structure of insurance schemes in the agriculture sector has failed to reach small-scale and marginal farmers who are most in need of risk transfer mechanisms. Based on a farmer survey, we extracted lessons from implementing a bundled insurance scheme as a pilot project to explore the utility of farmer organizations as an entry point for engaging different farmer groups and ensuring they can understand the WII insurance products and can make informed choices.
The survey results show that efforts made at the outset to understand contextual issues and challenges contributed to an effective product design and rollout approach. The rollout was more effective due in part to a partnership with an established local organization while adopting an aggregator model. Covid-19 mobility restrictions prevented full implementation of the rollout.
Index insurance bundled with mobile weather and agronomic advisories increased farmer resilience and reached diverse groups. Farmers emphasized that being able to assess the costs and benefits based on understanding how key elements of the product work is key to their future engagement with such products, which highlights the importance of investing in awareness raising through a blend of print, verbal and visual tools that make complex products understandable to stakeholders with low levels of literacy.

CONTEXT: Dairy farmers are affected by climate change (CC). To reduce the negative effects of CC, farmers need to take numerous adaptive measures. The ability to adapt is context-specific and there is a dearth of research on the adaptation and adaptive capacity (AC) of dairy farmers in village tank cascade systems (VTCS).
OBJECTIVE: The study investigates dairy farmers' perception of CC, their AC, adaptation, and the social and institutional drivers of AC and adaptation in the two selected VTCS in Sri Lanka. The knowledge of this is vital in planning specific interventions to enhance the climate resilience of farmers.
METHODS: The level of CC adaptation and AC was measured using the Activity-based Adaptation Index and Adaptive Capacity Index. Using an ordered logistic regression model, the determinants of the CC adaptation were examined. Social dimensions of AC are studied by comparing AC scores across social groups differentiated by income and gender. Data were collected from 200 dairy farmers in two VTCS in the Anuradhapura District, North Central Province of Sri Lanka, where dairy farming is predominantly practiced. Pre-tested structured questionnaires were used for data collection.
RESULTS AND CONCLUSION: Pasture shortage, reduction in milk yield, and growth retardation of animals are reported as perceived CC effects by a majority of dairy farmers. The adaptation strategies mostly implemented by dairy farmers are aimed at reducing the effects of CC on animal physiology. A lesser number of farmers implement adaptation strategies that address pasture shortages. Farmer's perception of CC, socioeconomic characteristics and resource endowment determine the level of adaptation, while the AC moderates the relationship between perception and response to CC. The institutional and social context in which dairy farmers operate differentiates the AC of farmers. Women and poorer farmers tend to have a lower AC. The difference in AC across these social groups is explained by access to resources. The study recommends interventions to address social gaps in AC and highlights the importance of strengthening and expanding extension services and rural credit facilities.
SIGNIFICANCE: Globally, fewer studies have been conducted on the impacts of climate-related risks on dairy farming systems and adaptation in comparison with such risks and adaptation in crop farming. This study provides insights into resource-poor dairy farmers' responses to CC and potential solutions in using common resources in VTCS to reduce vulnerability to CC.

This study focused on fulfilling the demand for a comprehensive investigation of groundwater quality in the North Central Province (NCP) of Sri Lanka to achieve United Nations Sustainable Development Goal 6 (Ensure availability and sustainable management of water and sanitation for all). The NCP was selected as the study area due to its highest prevalence of chronic kidney disease with unknown etiology within Sri Lanka. Here, 334 shallow and deep groundwater samples were collected at the end of wet and dry seasons, respectively. Results revealed that elevated and unexpected levels of salinity, hardness, fluoride, nitrate, sulfate, and dissolved organic carbon and the alkaline nature of groundwater were the main issues, and the Ca-HCO3 type was dominant in the groundwater. Water quality index analyses showed that 8.9% and 13.8% of wells had poor quality undrinkable groundwater in wet and dry seasons, respectively. Only 7% of samples were susceptible to sodium and salinity hazards for irrigational use. Reverse osmosis technology with a softening and activated carbon pretreatment process was identified as the most suitable way to treat groundwater with high salinity for many regions of the NCP. The groundwater quality atlas for the NCP created by this study was very useful for making a master plan of safe drinking water supplies and developing and implementing cost-effective water purification technologies in the NCP.

Drought is an almost annual phenomenon affecting many parts of Sri Lanka, causing huge damage to agriculture and losses to the broader economy in general and farmers in particular. Climate change threatens to exacerbate these risks. Risk transfer mechanisms, such as crop insurance schemes, may help buffer farmers against these hazards and has gained attention as an adaptation response to become an important element in agricultural risk management. Despite the numerous efforts over several decades to popularize crop insurance as a risk transfer tool in the country under heavy subsidies, farmers’ voluntary enrollment in crop insurance has been very low. Therefore, understanding the farmers’ behaviors and attitudes towards crop insurance and the potential of such programs in emerging climate-induced vulnerabilities is critical to enhancing the welfare of the farming community. This paper assesses the factors that influence willingness to enroll for crop insurance among farmers in irrigated and rainfed farming system in the drought-prone North Central Province of Sri Lanka using a logistic regression model. The study sample consisted of 149 irrigated farmers and 51 rainfed farmers selected randomly. Regression results show that farmer’s age, agriculture as the primary source of income, irrigation as the source of water, and availability of supplementary water source are significantly related to willingness to pay (WTP) for insurance. The overall results indicate the role of household socioeconomic factors and their contextualized risk perceptions shape the adoption decision of crop insurance. The findings of the paper contribute to that end through primary data from a rainfed and irrigated areas in the province. Although the present research was carried out in a limited area, the study area is dominated by the traditional nature of agricultural practices by smallholder farmers in a drought exposed environment, the findings of the study should apply to the rest of the dry zone areas in the country. The results on factors affecting farmers’ willingness to purchase crop insurance assist the practitioners and policymakers to draft the guidelines and strategies for more inclusive interventions for agriculture risk management and building farmer resilience.
