Balancing irrigation and hydropower: Case study from Southern Sri Lanka AgEcon
Molle, Francois; Jayakody, Priyantha; Ariyaratne, Badugodahewa Ranjith; Somatilake, H.S..
This report analyzes a case from southern Sri Lanka, where the Samanalawewa dam and the Kaltota Irrigation Scheme (KIS) compete for the water of the Walawe river. At the catchment level, it is shown that dam releases are well attuned to the needs of KIS and to the occurrences of natural runoff, and that little of the dam water is "lost" to the river.

Institutional changes to reduce land preparation delay in the North Central Province of Sri Lanka. AgEcon
Loeve, Ronald; Somaratne, Pallewatte G.; Ariyaratne, Badugodahewa Ranjith; Anputhas, Markandu; Jinapala, Kiribandage.
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.

Institutions, impact synergies and food security: a methodology with results from the Kala Oya Basin, Sri Lanka AgEcon
Saleth, Rathinasamy Maria; Dinar, Ariel; Neubert, Susanne; Kamaiah, Bandi; Manoharan, Seenithamby; Abayawardana, Sarath; Ariyaratne, Badugodahewa Ranjith; de Silva, Shyamalie.
The success of development programs depends on the role of underlying institutions and the impact synergies from closely related programs. Existing literature has limitations in accounting for these critical factors. This paper fills this gap by developing a methodology, which can quantify both the institutional roles in impact generation and the impact synergies from related programs. The methodology is applied to the Kala Oya Basin in Sri Lanka for evaluating the impacts of three development programs and 11 institutions on food security. The results provide valuable insights on the relative roles of institutions and the varying flow of impact synergies both within and across impact pathways.
