2. What is it
 Diversion based irrigation (DBI) is a concept based on gravity led
irrigation system which diverts portion of water from a natural source
like spring/ mountainous stream or any Water Harvesting Structure
and uses it with or without intermediate storage for the purpose of
irrigating crops.

3. Why DBI
 Providing protective irrigation during Kharif season.
 Increase income of the poor farmers by ensuring irrigation during Rabi
as lack of access to irrigation is one the most predominant causal factor
for the low levels of productivity.
 Higher levels of un-certainty in the whole agriculture of this region.
 It require small investments and lesser maintainace cost
 It has the potential of addressing food security issues of small and
marginal land holders.
 Zero energy irrigation system

4. Objective of the DBI Project
 To develop water management skill and management of crop planning.
 To increase the irrigation command area.
 To reduce water losses in existing DBI System.
 To reduce the soil erosion in command area by doing various treatment
of soil and water conservation.
 To adopt the new technique of improved agriculture. Improved seed,
use of bio-pesticides for vegetable plots.

5. Location of the Project Area

6. Indigenous DBI System
 The indigenous DBI is basically a conveyance of
irrigation water through channels drawn from
mountainous perennial streams.
It is adopted in hilly terrain, mostly in the upper
reach by constructing a temporary barrier across
stream made out of stone and mud.
divert a portion of post monsoon delayed flow of
natural stream from main flow line.
Diverted water is then fed into a channel passing
almost along the contour line.
The channel excavation is done through ‘Lahya’
system (practice of working together on each
others field by the benefiting families. It is
prevalent in tribal areas of Nandurbar district)

7. Limitation of Indigenous DBI System
 Seepage losses, leakages at critical sections of channel
and on nallas crossing.
 Inadequate discharge is resulted from insufficient
head of a temporary barrier and also requires
maintenance.
 The lesser carrying capacity of channel provides
irrigation to limited area.
 Existing DBI had limited area under irrigation and
constraint of loss in valuable irrigation water thereby
benefiting limited tribal families.

8. Process Followed
 Formation of water user groups (UGs) at village level.
 Mobilized the user group for participation in implementation of the system right from the
planning stage.
 Technical Survey of the sites as well as prepared the designs and estimates.
 Construction work had carried out under the supervision and active participation of UGs.
 Proper orientation and trainings imparted to the UGs to develop better management skills
especially operation and maintenance of the assets as well as effective utilization of
developed resource etc.
 Introduced democratic decentralization in decision-making about the equitable water
distribution with regard to the crop cultivated and area covered.
 Introduced the Crop Planning and integrated the promotion of agriculture and allied
activities.

9. Key Component of the Project
 IMPOUNDING STRUTURE –Small, Medium and spring.
 CHANNEL DEVELOPMENT
 LAND DEVELOPMENT-Area treatment, seeding and
plantation.
 IMPROVED AGRICULTURE-Improved Variety and bio
pesticides
 Capacity Building- Training and exposure etc.

10. Water impounding structure
To create sufficient head to divert a portion of
delayed flow of natural stream.
 it is a small weir type permanent barrier of
about 1.0m height with the provision of open gate
is constructed across a stream.
Inbuilt opening in accordance with water
requirement of command area is provided to water
impound structure to which channel or pipes are
connected.

11. Channel Development
Channels are laid almost along the contour
line with gradient of about 2.50 m to 10 m per
kilometer is kept for keeping velocity of flowing
water under control.
The provision of pipes is aimed to reduce
losses of valuable irrigation water at critical
section of channel and while crossing nallas.
In most cases pipes are dismantled after Rabi
season and reinstalled in next season.
 Two sides are developed with whole pipeline
for channel development.

12. Land Development
The landscapes in DBI command are treated with
measures like field bund repair, construction of new
field bunds, stone bund, proper field outlets to bund
and plantation to reduce soil erosion and to improve
water retention.
The treatments were executed by tribal farmers in
accordance with land slope and soil type.
 Plantation of the horticulture plant like mango and
apple ber is done the waste land.

13. Improved Agriculture
introduced improved variety of Gram, Maize and
vegetables like Chilly, Brinjal, Tomato, Okra, Cluster
bean, Onion, Garlic, and Cauliflower etc.
 High valued crops like Ginger and Strawberry were
also introduced to enhance the crop productivity.
 Providing the Package of Practice of Vegetables.

14. Capacity building of UGs
 Training program major focus was the
adaptation of the POPs of various
vegetable species
 Organized the exposure for the farmers of
the user groups
 On field Demostration

15. Impact of the DBI Project
After the intervention, 46 DBI
structures directly benefits
628families covering areas of 1106
acres of land against the 392 families
covering 628 acres earlier.
60.20 % more families benefitted
76.11% more land brought under
irrigation to pursue Rabi Cultivation.

18. Benefits to the community
 The farmers have transformed from subsistence to surplus producers.
In case of Kharif crop they are no longer dependent on rain water as
facility of protective irrigation available.
 Most of the farmers started cultivating vegetable for their home
consumption. In addition to that they are cultivating Maize, Gram,
wheat, etc in Rabi that adds to their food sufficiency and security.
 Farmers have also started growing high value crops gradually like
Ginger, Strawberry and other seasonal vegetables.
 Soil erosion is reduced and better water efficiency achieved due to the
farm bunding / Land development work in the command area of DBI
Scheme.
