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.

This manuscript undertakes a review of current published information (peer-reviewed and grey literature) on Chronic Kidney Disease of Unknown Etiology (CKDu) in Sri Lanka. It attempts to provide an overview of the possible environmentally-induced causal factors that have been implicated in the development of the disease, and identifies the gaps in research and recommends potential areas for future research. The review specifically captures the potential role that agriculture and water resources may play as causal factors in the development of the disease, and calls for a systematic approach and stresses the need for an integrated multi-disciplinary research effort to address the problem.

A reliable supply of water is critical for agricultural intensification and yield improvement. Technological devices that lift, transport and apply water contribute to increased yield from improved crop varieties and high input cultivation. The increasing use of motor pumps is a significant contribution to the development of small-scale irrigation. The objective of this study was to identify and analyze the trajectories of technological innovations and uptake for agricultural water management in farming systems in Sri Lanka, with a special focus on identifying impacts, emerging issues and potential responses to the rapid proliferation of motor pumps in the intensification of agriculture in the country. The Government of Sri Lanka promoted the rapid adoption of water pumps through interventions such as the development of groundwater wells for agriculture; provision of subsidies and credit facilities for purchasing micro-irrigation equipment; and government policies on tax, tariffs and extension support. At the same time, the high profit margin realized from cash crop cultivation motivated farmers to invest in water lifting and related technologies. Finally, water scarcity and restrictions on the use of surface water, i.e., canals, prompted a shift to using water-lifting technologies to pump groundwater. The use of water pumps in agriculture has expanded the area under cultivation; increased cropping intensity, especially during the dry seasons; changed the cropping pattern from low-return rice cultivation to high-return cash crop cultivation; and enhanced household incomes. Expanded and intensified cultivation has provided more opportunities for women to participate in agriculture, generating additional income, and enhancing their purchasing power and decision-making at the household level. Some farmers do not have groundwater wells and water pumps because they lack the necessary capital to make the initial investment. Smallholder farmers, in particular, are reluctant to risk their limited income on new technologies. This may lead to the further marginalization of poor farmers. Inclusive intensification will require helping farmers to access irrigation technology, for example, through carefully targeted subsidies and access to credit. Using water pumps can provide benefits to both users and non-users, but uncontrolled groundwater extraction may also create new problems by putting enormous pressure on common property resources. The government will need to take on a dual role to both promote the inclusive growth of small-scale irrigation, and to prevent and mitigate its negative environmental impacts. This second role may include establishing a regulatory system, setting standards for well construction, and monitoring and enforcing standards on extraction and water quality. There is an urgent need for institutional measures and governance arrangements to guide and regulate groundwater irrigation, especially in the context of intensive cultivation using shallow aquifers.
