Presentation by Jeremy Bird, DG, International Water Management Institute, at the CCAFS Workshop on Institutions and Policies to Scale out Climate Smart Agriculture held between 2-5 December 2013 in Colombo, Sri Lanka.

1. Institutions and Policies for Scientific Water Use:
Game changers for climate risk management in agriculture

CCAFS Workshop
Colombo, 2-3 December 2013

2. Humanity’s greatest challenge
To feed 9 billion people in
2050, we need to produce
50-70% more food and raise
nutrition levels…
…and at the same time
reverse environmental
degradation
…and reduce vulnerability to
climate shocks

3. Climate change is an additional stress
AR5: Global surface temperature change for the end of the
21st century is likely to exceed 1.5oC

4. Managing Variability
TOO LITTLE…
TOO MUCH…

5. Physical scarcity:
Water resource
development approaching
or exceeding sustainable
limits
Water scarcity is already common
Economic scarcity:
Water resources can meet
needs; but human,
institutional and financial
capital lacking to actually
harness and use these
resources
Institutional scarcity:
Institutions limit access to
certain groups and exclude
others

8. CLIMATE CHANGE VULNERABILITY HOTSPOTS -1
Exposure Index based on:
Frequency of exposure to
historical droughts, floods,
cyclones
Sensitivity Index based on: Population
density, % employed in agriculture,
irrigation water availability, agricultural
diversity (crops diversity, livestock
farming, fishing)
0 – lowest vulnerability
Adaptive Capacity Index
based on: education level,
poverty incidence, level of
infrastructure development
100 – highest vulnerability

9. CLIMATE CHANGE VULNERABILITY HOTSPOTS -3
Highly vulnerable areas are:
• Typical farming areas
• Have low socioeconomic and
infrastructural assets (low adaptive
capacity)
• Show high levels of exposure to
historical climate extremes
Anuradhapura
Nuwara-Eliya
• Primary food producing areas - rely
heavily on water availability for
agriculture

11. One response has been irrigation, but…
…. we seem to be reaching the limit of ‘formal’ irrigated area

12. Instead, look at a broader perspective – the rainfed to
irrigated continuum

13. Need to re-think water storage to manage rainfall variability
– but institutional complexity

14. Game changers for adaptive water management –
do the right incentives exist?

15. Sustainable Agricultural Intensification

16. Unleashing the potential of 2 billion small-scale
farmers who collectively produce 70% of current
global food. WLE tackles 3 key issues.
1. Ensuring the efficient use of resources so that farmers can profit with limited
environmental impact.
2. Restoring productive capacity of degraded rainfed and irrigated landscapes and
impaired water systems to improve incomes and livelihoods of farmer.
3. Reducing risk and uncertainty of poor farmers within rainfed and irrigated
landscapes resulting in improved productivity through the sustainable management of
land, water and ecosystems.

17. What if the benefits of canal
commands increase to meet
higher demand within the
resilience of natural ecosystems?
Identify incentives to influence
behaviour at all levels

18. What if the potential for
increasing the productivity of
agriculture in Sub-Saharan Africa
can be realized?
Identify policy measures and
business models

19. What if conjunctively managed surface
and ground water resources becomes a
reality?
Address both over-abstraction
and under-utilization

20. What if there is a greater balance
between natural capital and the
built environment?
Bringing ecosystem services
into the discussion on
sustainable intensification of
agriculture

21. Natural and built infrastructure… striking a
balance – increasing the total benefit stream

22. Examples of institutional and policy reforms
leading to more sustainable agriculture
growth exist….
others are being developed…
and more are needed

23. The Bright Spots Initiative
Comprehensive study of 286
cases in 57 countries where
individuals and communities
that have adopted sustainable
crop intensification systems.
Bright spots influenced:
12.6 million households
covering 37 million hectares
increased yields by an average
of 79% with average carbon
sequestration of 0.35 t C ha-1
yr-1.

24. #1: Jyotigram in Gujarat, India
Upscaling the recovery of groundwater tables and reduced
electricity usage
– “Free’’ electricity led to groundwater
overdraft
– Recommended separation of electricity
supply to villages and pumps and
rationing of pump supply
– It has brought substantial improvement in
and outside the water sector:
• Ground water balance improved
• Electricity distribution losses down from 31%
to 21%
• Farmers get continuous good quality electricity
schedules. Domestic supply 24/7
• Yield increases -recent agricultural growth rate
is 9.6%, the highest in India.

25. Ground water policy reform in West Bengal
1. Why groundwater (GW) based solution for
Bengal?
•
•
2.
High underutilized GW potential
Low agricultural productivity
Research led to removal of water permits
and rationalization of capital costs of
initial electrification including tariffs
3. Policy change could benefit more than 5.6
million smallholders farmers
4. After policy implementation, the demand
for electric pumps has risen rapidly
5. Need efficient irrigation to minimize
energy use

26. Small-scale irrigation in Africa
Back on the agenda in Ghana, Tanzania, Zambia,
Ethiopia, Burkina Faso and elsewhere
Unlocking the potential for
smallholder agriculture to
improve the lives of
smallholder farmers in 5
countries in sub-Saharan
Africa and 2 states in India
(Giordano et al, 2012)

27. Outputs
Smallholder Agricultural Water Management: Potential to Impact

SSA: motor pumps
• 122 million potential rural beneficiaries
• Net revenues up to US$7.5 billion/yr.
Tanzania: motor pumps could benefit 2-3
