Climate, agriculture, and food security Climate change is one

stress among many affecting agriculture and the population that depends on it

Observations: Increased drought Persistent drying trend in parts of Africa has

affected food production, including freshwater fisheries, industrial and domestic water supplies, hydropower generation (Magazda, 1986; Benson and Clay, 1998; Chifamba, 2000; Iglesias and Moneo, 2005)

Conclusions

While global production appears stable, . . .

. . . regional differences in crop production are likely to grow stronger through time, leading to a significant polarization of effects, . . .

. . . with substantial increases in prices and risk of hunger amongst the poorer nations

Most serious effects are at the margins (vulnerable regions and groups)

Key differential vulnerabilities Climate change is one stress among many now

affecting agriculture and the population that depends on it

Integration of results and stakeholder definition of adaptation strategies are essential to formulate assessments relevant to policy

Potential future consequences depend on: The region and the agricultural system [Where?, The

baseline is important] The magnitude [How much? Scenarios are important] The socio-economic response [What happens in response

to change? Adaptive capacity (internal adaptation) and planned stakeholder adaptation and policy]

Check list and ranking of potential vulnerabilities - Examples

Components of the farming system particularly vulnerable Stress on water/irrigation systems Domestic agricultural production Food shortages that lead to an increase in hunger Agricultural exports Prices to consumers Government policies such as agricultural pricing, support,

research and development Greater stress on natural resources or contribute to environmental

degradation (e.g., through land-use change, soil degradation, changes in water supply and water quality, pesticide use, etc.)

Research/extension system capability for providing adaptation advice to farmers

Technological options in place

Key vulnerabilities

Individuals particularly vulnerable to environmental change are those with ….

• Relatively high exposures to changes• High sensitivities to changes• Low coping and adaptive capacities• Low resilience and recovery potential

Current vulnerability• Dependence on the Nile as the primary water source• Large traditional agricultural base• Long coastline already undergoing both intensifying

development and erosion• Problems derived from population increase• Agriculture entirely based on irrigation (water from

Assisting tools to stakeholders

Need quantitative estimates Models are assisting tools Surveys to stakeholders are assisting tools

for designing bottom-up adaptation options

Key variables for agronomic and socio-economic studies: crop production, land suitability, water availability, farm income, …

Before getting started ….

Models are assisting tools, stakeholder participation is essential

The use of models requires high degree of technical expertise

The merits of each model and approach vary according to the objective of the study, and they may frequently be mutually supportive

Therefore, a mix of tools and approaches is often the most rewarding

Quantitative methods and tools

Experimental Analogues (spatial and temporal) Production functions (statistically derived) Agro-climatic indices Crop simulation models (generic and crop-

specific) Economic models (farm, national, and regional)

– Provide results that are relevant to policy Social analysis tools (surveys and interviews) –

Allow the direct input of stakeholders (demand-driven science), provide expert judgment

Experimental: Effect of Increased CO2

Near Phoenix, Arizona, scientists measure the growth of wheat surrounded by elevated levels of atmospheric CO2. The study, called Free Air Carbon Dioxide Enrichment (FACE), is to measure CO2 effects on plants. It is the largest experiment of this type ever undertaken. http://www.ars.usda.gov

Models - Advantages

Models are assisting tools, stakeholder interaction is essential

Models allow to ask “what if” questions, the relative benefit of alternative management can be highlighted: Improve planning and decision making Assist in applying lessons learned to policy

issues Models permit integration across scales,

sectors, and users

Models - Limitations

Models need to be calibrated and validated to represent reality

Models need data and technical expertise

Models alone do not provide an answer, stakeholder interaction is essential

Economic models

Consider both producers and consumers of agricultural goods (supply and demand)

Economic measures of interest include: How do prices respond to production amounts? How is income maximized with different

production and consumption opportunities? Microeconomic: Farm Macroeconomic: Regional economies All: Crop yield is a primary input (demand is

Use the DSSAT models to evaluate the use of alternative existing varieties and changes in the timing of planting to optimize yield levels or water use

Applications of CROPWAT to answer adaptation questions

• Can the water/irrigation systems meet the stress of changes in water supply/demand?
