Abstract
This study attempts to determine the willingness to pay of downstream households under
irrigation for improved irrigation water supply from protected Uluguru Mountains’
watersheds in the upstream. A total of four villages, under traditional irrigation system,
and the other two under improved traditional irrigation system, were randomly and
purposefully, selected for survey. Primary data were collected using Contingent Valuation
method (CVM) by combining close-and open-ended question format. Excel and STATA
10.0 packages were employed in the analysis of descriptive and inferential data
respectively. Paddy and tomatoes were the most grown crops under irrigation system while.
banana and eggplants were the least grown crops under the system. Bid price and income
from irrigated crops had the strongest negative and positive significant (P<0.01)
relationship respectively, with WTP for improved irrigation water supply for both closeand
open-ended question formats across the two micro-irrigation systems. It was also
found out that the households, in the Uluguru downstream, would be willing to pay for
improved irrigation water supply if the new fee ranged between TAS 14 545.95 and TAS
17 900.80 per household per year and aggregate WTP was TAS 78 519 038.00 per year for
5 398 households under irrigation systems. Majority of households across the two systems
were aware of the presence of water governing institution, however, the institutions were
rather weak. A few respondents, (21.3%) and (21.2%), believed that the association of
irrigation farmers and village water committee respectively were at least performing well
amongst water-governing institutions. Most of households, across the two systems,
believed that the price of improved irrigation water supply should be volume-based and
that water user association (WUA) should be given the mandate to collect the fee and
manage water resources.
