Abstract:
Abstract: The main objective of this study was to assess the present status of
knowledge and perceptions of the communities on tank cascade management and
ecosystem services provided by tank cascade systems. Aluthhalmilla wewa, Palu-
gaswewa, and Bandarakumbukwewa tank cascade systems situated in the Anuradha-
pura District were selected for the study. These cascades are under the jurisdiction of
the Department of Agrarian Development. Secondary and primary data were col-
lected on the tank cascade's socio-economic, ecological and managerial environment
and related areas. Primary data were gathered using key informant interviews. Mixed
methods were used to analyse data. According to the findings, most village commu-
nities use tanks for farming related activities, bathing and washing, etc. However,
none of them use the tank water for drinking as they think water is polluted. A statis-
tically significant relationship (P<0.05) was not observed between the occupation and
age of the communities with their knowledge of the ecosystem services of the tanks,
while the education level of households showed a positive relationship (P<0.05).
However, there was a lack of knowledge on the full range of ecosystem services of
the tank cascades, which needed to be enhanced. All the respondents were in view of
the tank and associated environment need to be improved, and while they were fairly
satisfied with the activities of the farmer organisations and the officials of the Depart-
ment of Agrarian Development. Farmers agreed that this needed improvement to
foster the full potential of the tank cascade systems. All the respondents were willing
to contribute to improvement and conservation the tanks' ecosystems. Therefore, it
could be recommended that it is required to enhance the knowledge among the stake-
holders and follow an inclusive and integrated approach with the participation of
farmers and farmer organisations and the officials of the Department of Agrarian Ser-
vices.
