Assessing farm responses to the uncertainty of climate change: application to an irrigated area in Northern Tunisia
Résumé
Decision-makers are often confronted with contradictory demands when it comes to developing projects to evaluate and foster suitable strategies for adapting to global warming. In fact, few quantitative methods for assessing the impact of climate change on resilience and adaptive capacity have been defined and used. Furthermore, the tendency has been to treat the impact of climate change as a stand-alone activity, whereas it should be integrated into development projects, plans, policies, and strategies, in order to reach a compromise solution, a trade-off between the costs and benefits of different criteria (economic, social, environmental etc.). This paper presents a study using a bio-economic model to assess, at farm level, the impact of climate change in northern Tunisia by analysing farm production systems behaviours as well as economic and environmental variables.
