Introduction of community water supply projects, implemented and managed by the community with an initial support from governments or international organizations has been considered as a useful strategy to provide access to safe drinking water to rural communities. Sri Lanka has also adopted this strategy through the Community Water Supply & Sanitation Project. Since there were concerns about the sustainability of numerous water schemes implemented throughout the country, a research was carried out in 20 community managed water schemes in eight Divisional Secretariat divisions in Kandy district to assess the sustainability of community based rural water supply projects using a methodology adopted by the UNDP and World Bank in six other countries. Participatory research methodology tools were used for the assessment based on 5 sub-indicators, such as physical condition, operation and maintenance, consumer satisfaction, financial management and willingness-to-sustain the system. The results show that the community water supply projects to provide water to rural areas of Kandy district has been a success since 14 out of 20 schemes were found to be sustainable indicating that the strategies followed during the project implementation have succeeded. However, the study has also highlighted areas which require further attention to ensure that these systems would continue to provide the expected services and improve the functioning of other potentially sustainable schemes in the longrun. A capacity building program along with an institutional arrangement to provide the support services by the authorities, at least in the short term, is considered vital to help improve the Community Based Organizations and to make them capable and mature entities.
Sri Lanka, with more than 2500 years of hydraulic civilization, has constructed highly complex systems of irrigation in the Dry Zone. Kings formulated the rules in consultation with high officials in the Kings' court. The King was the source of the laws. This ancient administrative system gradually changed after colonization and attention focused more on written rules and regulations of the government legislations than those based on customs, norms, and traditions of Sri Lanka. There are more than 50 legislations enacted in relation to the development and management of water resources along with the establishment of a large number of institutions. Despite all these, water resources are being degraded at an alarming rate. A preliminary study showed that there were adequate legal mechanisms and institutions to prevent water resources degradation. This study was carried out to determine the effectiveness of regulations and associated institutional arrangements to prevent stream encroachments. Two villages between Peradeniya and Gampola along the Mahaweli river were selected for the study. Questionnaire surveys, focus group discussions among institutional officers and interviews were conducted in these villages. The results showed that the existing regulatory mechanisms to protect stream reservation covered all aspects including eviction of encroachers. However, there are serious deficiencies in implementation of such regulations such as the lack of coordination among institutions, procedural lapses, political interference, and less enthusiasm of state employees to implement rules and regulations. The encroachers tend to occupy the reservations due to landlessness, poverty, and the social cohesion among their own communities.
Performance assessment of irrigation systems plays a vital role to self-evaluate them so that interventions could be made to improve the functioning of the systems. This study was conducted to assess water delivery and supply performances and the agricultural productivity in three major irrigation systems, namely, Batalagoda, Hakwatuna Oya and Kimbulwana Oya in the upper Deduru Oya river basin and comparatively evaluate them based on the estimated values of selected performance indicators. Secondary data were collected from these three systems with respect to rainfall, yield, cultivation performances, water supply and delivery for the period of 2012/2013 Maha and 2013 Yala seasons. The results showed that the relative yield of more than 1.0 was achieved only during Maha season at Batalagoda and Hakwatuna Oya irrigation systems. None of the systems were able to reach the indicative paddy yield of 5 Mt/ha during the Yala season. The overall comparison of performance indicators during both seasons have shown that the performance of Hakwatuna Oya irrigation system was relatively better compared to Batalagoda irrigation system followed by Kimbulwana Oya irrigation system. The water scarcity during Yala season at Batalagoda and Hakwatuna Oya irrigation systems has resulted lower crop productivity. Irrespective of high relative water supply, the actual yield is much less than the indicative yield during both seasons at Kimbulwana Oya irrigation system. The reasons for poor water and crop productivity during both seasons at Kimbulwana Oya irrigation system needs to be explored in detail so that interventions could be made to improve the system performance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
