note = {Recent development in agricultural und industrial production leads to increasing pollution of the water sources in the Mekong Delta of Vietnam. According to the "Vietnam Environment Monitor 2003 - Water", no safe drinking water is provided to approximately 40 % of the total population. Thus, environmental institutions and governments became aware of the looming fresh water crisis. As a result, the "National Rural Clean Water Supply and Sanitation Strategy" (NRWSS) was elaborated as part of the national "Poverty Reduction Strategy Paper" to take responsibility for the Millennium Development Goals.
The reuse of waste/wastewater for agriculture may be a low cost solution in water treatment and at the same time a significant contribution to food production. The presented socio-economic study was conducted during the course of the interdisciplinary SANSED-Project in 2003/04, aiming to identify criteria for a sustainable wastewater treatment system. Therefore, User- and Non-User-operating farm households' (OFH) attitudes towards and acceptance behavior of biogas plants (BGP), modern latrines (ML) and biogas sludge (BGS) as principal components of an ecological wastewater management system were analyzed and evaluated. Referring to the latter, the use of human feces in the biogas technology was a major point of interest. By means of a detailed questionnaire, the survey aimed to achieve information about the OFHs' environment and interactions. LANGENHEDER'S decision-making-theory together with KOLLMANN'S use-acceptance-model on the OFH defined by DOPPLER as socio-economic system constitutes the basis of this research approach. Within the sample 218 OFHs in three selected communities of the Mekong Delta as well as representatives of the local government, universities and other institutions were interviewed. The study leads to the following results and recommendations:
80 % of the surveyed OFHs have no ML, 10 % have no latrine at all. Generally, the population is aware of the hygienic and environmental threats, but real commitments to solve the problem are still missing. The User OFHs dispose of a higher living standard and educational level. Apart from their farming activity, they hold down a non-farm job and thus, dispose of more steady income and have easier creditworthiness. The principal OFHs' problems are lack of capital and professional knowledge as well as shortcomings in the access to further training.
Most of the households know about the governmental intentions to substitute fishpond-latrines and to promote the use of organic fertilizer instead of untreated feces. In general the OFHs perceive BGP, ML and BGS-use as progressive, but restraining factors for their investment and sustainable utilization do exist. The principal restricting determinants are:
BGP: Lack of capital and therefore of a customized microfinance system, the dependency on piggery as substrate input source and its market instability as well as the lack of monitored construction quality standards and difficult emptying procedure of the system.
ML: Lack of economic inducement, ML-inappropriateness i.e. luxury good that doesn't fit to the living standard (average dwelling) on the countryside.
BGS: Lack of information, specifically nescience about BGS-use and earthworm breeding, difficult, space intensive and time-consuming handling, small produced quantity, relatively low market value.
The acceptance of these components suffer shortcomings in communication including reliable technical assistance and professional training using demonstration units for capacity building as well as choices of models for adaptability.
The Health Care Centre, the Agricultural Extension Service and research institutions should work closer together on the standardization and general widespread introduction of BGP with connected ML as it would provide an efficient solution with synergy effects reducing the installation and fix costs, superseding the emptying procedure, enabling the safe reuse of night soil and alleviating the strong dependency of BGP-utilization on piggery. The Agricultural Extension Service already tries to offer and transmit information accordingly, but the institutional structure and efficiency referring on its internal organization, available quantity of field service staff and its capacity are insufficient.
Further recommendations to improve the acceptance and dissemination rates include the establishment of user-societies/groups, demand-oriented offers of custom-to-fit-system, economic inducement and service network for microfinance at the grassroots level. The second phase of SANSED-Project offers the opportunity to consider the recommendations and to tackle the need for acceptance and dissemination research.},
