Abstract:
llage Tank Cascade Systems (VTCSs) evolved as interconnected eco-
logically compatible hydraulic systems in the dry and intermediate zones in Sri
Lanka. These VTCSs are vital to enhancing climate-resilient livelihood and food se-
curity for rural peasant communities. Water scarcity has had a detrimental effect on
irrigation-based paddy cultivation in dry zone areas and currently, it has become a
global scenario. Sustainable Development Goals (SDG) 2 and 6 are highly concen-
trated on overcoming water-related issues and providing equal opportunities for the
community in the next couple of years, especially in developing countries. VTCSs
are playing a dominant role at the micro level in enhancing the coping capacity of
rural peasant communities in dry and intermediate zones in Sri Lanka. Therefore, the
effectiveness of the Ovilana village tank to achieve SDG at the rural level through
VTCS Sri Lanka was studied in this research. Ovilana Tank is fed by the Murutawela
Reservoir, and it provides irrigation facilities for 48 paddy farmers to continue paddy
cultivation and animal husbandry. Questionnaire survey and interview methods were
followed for the primary data collection in Madagama GND in Weeraketiya DSD.
Data were analyzed by using descriptive statistics and thematic analysis. Based on
the Ovilana tank 32 acres of paddy lands were cultivated by 48 traditional farmers
during the Yala and Maha seasons without any interruptions. Drought resilient “AT
362” paddy variety, the systematic role of farming society, incorporation with tradi-
tional knowledge and rituals during all stages of cultivation, water and tank conser-
vation strategies, animal husbandry, crop rotation, equality, and accountability caused
accelerated socioeconomic and ecological sustainability of the Ovilana tank. Moreo-
ver, this case study proved the suitability of VTCSs for achieving sustainable devel-
opment and empowering the rural communities in Sri Lanka
