tansa valleybest & worst case
best scenario
_if we have an average rainfall and all our tanks are
full
worst scenario
_if we have too much rainfall (more than the decade
highest)
_if we have too little rainfall (less than the decade
lowest)
problems
-
_dams are to small to stop
the water
_flooding
_our tanks are not full and
we cannot provide enough
water for the locals
solutions
_we have enough water for 2 cycles of agri-
culture
_we open up the dams to avoid breaking
and save only the amount of water needed
_we provide percolation pits at regular inter-
vals
_it helps in ground water recharge
_we have to use our back up tank which will
need to be replinished the next monsoon

1. awareness and motivation
2. identification with the project
3. trust the organisation and the government
4. understand the sense of the project
5. through instruction the locals learn a responsible and sustaina-

6. ensure/ guarantee the one‘s own initiative
during
1. the project is meant for the benefit of the people. their in
terests are central for the project and not the ones of the organisa-
tion or the government
2. participation and collaboration of the locals are essentially
for the achievement of the project. the locals must join the
discussions and must be allowed to take decisions
3. through participation the locals start to identify with the project
4. periodic meetings with the locals help to clarify questions
or doubts. the locals are taken serious and trust the project
5. locals must be proactive

risks
1. if we support one village, the villages in the neighbourhood
might be less strong
2. rich become richer - poorer become poorer
3. we have to make sure that the maintenance is done in a
propper way
4. the local people won‘t trust us from the beginning on. we
have to win their confidence
5. the interventions could cost a lot of money and time
6. unthought risks
if we don‘t achieve some of the goals of the project, at
least there will be an improvement for future develop-
ment.

tansa valleysustainability | ecology
risks
destruction/ interruption of the natural water circle
=> include locals in the planning process because they
know the site conditions. also involve people with
specific knowledge about the conservation of
bio- diversity.
destruction of the landscape (partially)
=> try to select the site which will have the least impact on
the environment.
more hotels and tourists produce more waste
=> waste management concept for the hotels
(waste management for a hotel is mandatory)
chances
the project facilitates a healthier living environment in the village
the site will be much greener, which will attract a lot of non-religious
tourists as well
it supports the ground water recharge
the generating of new landscapes will create living habitats for new
animals
the project can be applied in other villages as well

tansa valleysustainability | social impact
risks
Division of the social castes to achieve the ownership for the
water harvesting facilities
=> the design should provide an equal distribution of water
to all locals which are involved in the project
too strong control of an external investor
=> make the locals (agrarian economy) stronger and let
them become the investors
water theft
=> provide an interim body (between the government and
locals) for the supervision of the tanks and its use in
terms of distribution fights etc.
Some regulations which have to be implemented:
the interim body will be helpful in regulating:
1) equal wages for all hierarchy of workers within the village
2) make sure there is equal distribution of water
chances
the fund flow which will be initiated with the agrarian economy can
be invested in the social infrastructure like:
_schools
_workshops to develop local skills
_roads
_hospitals
_community sales centres
due to the equal distribution of water there is less corruption
it will help in integrating the local communities
