2. Agriculture and risk Production risk: expressed as yield and/or output variability due to diseases, higher quality requirement, climate change
Price risk: expressed as price volatility due to increasing liberalisation, reduced support etc.
Objective vs. Subjective risk
3. Risk Management Risk= exposure X hazard
exposure: probability distribution of the event
hazard: entity of the damage
Risk management strategies can be directed to reduce the level of exposure (mitigation) or the hazard (adaptation)
4. Risk Management Risk-sharing strategies:
Vertical integration
Contracts: marketing and/or production
Futures
Insurance: problems due to asymmetric information, systemic risks and catastrophes
Mutual funds
5. Risk Management On-farm strategies:
diversification (1): alternative crops to main cash-crops
diversification (2): alternative sources of income outside the agricultural sector
6. Agricultural Diversification
7. Industrial crops and diversification The uptake of industrial crops could bring benefits to
Agriculture: new value added products
Environment: increasing biodiversity and promoting sustainability
Economy: break-through in R&D

9. Sustainability and Resilience Sustainability is a measure of the ability of a stochastic system to function under a range of different environmental conditions, without flipping to a more degraded state: without losing its resilience (Arrow, 1995)
Resilience can be measured by the size of the disturbance that can be absorbed before the system flips into another state (Holling, 1973)

16. Conclusions Increasing diversification (biodiversity) could have significant effects on the ability of agro-ecosystems to withstand environmental and economic variability
Over the years, increasing specialisation in agriculture has meant a reduction of interspecific diversity in agro-ecosystems in the South of Italy and consequent loss of resilience
Increasing the ability of agro-ecosystems to face variability and to absorb exogenous shocks is a fundamental step towards a more sustainable agriculture
