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
Humanity’s greatest challenge

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

Managing Variability
TOO LITTLE… TOO MUCH…

Water scarcity is already common Physical scarcity: Water resource development approaching or exceeding sustainable limits
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

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)
Adaptive Capacity Index based on: education level, poverty incidence, level of infrastructure development
0 – lowest vulnerability 100 – highest vulnerability
![Page 9: Institutions and policies: Game changers needed for climate risk management in agriculture](https://reader035.vdocuments.us/reader035/viewer/2022070303/54b83c9f4a7959f8628b45e8/html5/thumbnails/9.jpg)

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
• Primary food producing areas - rely heavily on water availability for agriculture

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

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

Need to re-think water storage to manage rainfall variability – but institutional complexity
![Page 14: Institutions and policies: Game changers needed for climate risk management in agriculture](https://reader035.vdocuments.us/reader035/viewer/2022070303/54b83c9f4a7959f8628b45e8/html5/thumbnails/14.jpg)
Game changers for adaptive water management –
do the right incentives exist?
![Page 15: Institutions and policies: Game changers needed for climate risk management in agriculture](https://reader035.vdocuments.us/reader035/viewer/2022070303/54b83c9f4a7959f8628b45e8/html5/thumbnails/15.jpg)
Sustainable Agricultural Intensification
![Page 16: Institutions and policies: Game changers needed for climate risk management in agriculture](https://reader035.vdocuments.us/reader035/viewer/2022070303/54b83c9f4a7959f8628b45e8/html5/thumbnails/16.jpg)
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.

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
![Page 18: Institutions and policies: Game changers needed for climate risk management in agriculture](https://reader035.vdocuments.us/reader035/viewer/2022070303/54b83c9f4a7959f8628b45e8/html5/thumbnails/18.jpg)
What if the potential for
increasing the productivity of
agriculture in Sub-Saharan Africa
can be realized?
Identify policy measures and
business models
![Page 19: Institutions and policies: Game changers needed for climate risk management in agriculture](https://reader035.vdocuments.us/reader035/viewer/2022070303/54b83c9f4a7959f8628b45e8/html5/thumbnails/19.jpg)
What if conjunctively managed surface
and ground water resources becomes a
reality?
Address both over-abstraction
and under-utilization
![Page 20: Institutions and policies: Game changers needed for climate risk management in agriculture](https://reader035.vdocuments.us/reader035/viewer/2022070303/54b83c9f4a7959f8628b45e8/html5/thumbnails/20.jpg)
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

growth exist….
others are being developed…
and more are needed

– “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.

Ground water policy reform in West Bengal
1. Why groundwater (GW) based solution for Bengal? • High underutilized GW potential • Low agricultural productivity
2. 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
