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



tansa valleylocals

before

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-

ble use with water

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

after

1. a few people are responsible for the project

2. controlling


tansa valley

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
