Résumé : International audience
Several assessments of vulnerability and resilience have been attempted at a country level through composite indices but they are barely in accord with a holistic view of sustainable development. We suggest graph theory to structure a network of variables that depict vulnerability and resilience from a sustainable development perspective. Vulnerability is defined as the propensity to incur adverse shocks whereas resilience is the capacity to cope with their negative effects. We identify two control dimensions of vulnerability–resilience (economic and political) and three contingency factors (the social, environmental and the peripheral dimensions). The specificity of the control dimensions is rooted in their impact on all other sides of the pentagon. We propose an algorithm to select the key variables useful in building a composite index that conforms to the structure of these five dimensions while preventing loss of information. An application is provided on Singapore, which has been specified as a typical case of resilience.

Résumé : International audience
Vulnerability–resilience indexes fail to grasp all dimensions of sustainability, whereas sustainable development has gained momentum. We fill this gap with a hierarchical multimetric composite index (Net Vulnerability Resilience Index: NVRI) whose robustness relies on a mathematical algorithm based on graph theory. A worldwide application shows that (i) both vulnerability and resilience are policy-responsive and that (ii) there is no determinism for a country to remain vulnerable or resilient. The NVRI enables us to identify a country’s strengths and weaknesses and determine the policy orientations that should be implemented to achieve sustainability.

Résumé : Identify specific aspects of mixed farming systems. At the same time, certain practices seem to transcend the whole territory and relate little to the activities that dominate a zone. To be able to organize a follow-up of these promising complex systems at farmer and experimental level situation a first evolutionary assessment grid was sketched to enable the selection of the situations. This should allow a more detailed study of the functionality of farms where estimates can be made on the the performances and robustness of systems in terms ofsustainable development.

Résumé : International audience
The paper is an empirical study on contagion during the 1997–1998 Asian crisis. In line with Sander and Kleimeier [Sander, H., Kleimeier, S., 2003. Contagion and causality: an empirical investigation of four Asian crisis episodes. International Financial Markets, Institution and Money 13, 171–186], Granger causality among Asian economies on sovereign debt market is tested. Using a new measure of causality, we attempt to show the existence of shift contagion defined as significant differences in cross-markets links between tranquil and crisis periods. Firstly, non-existent links during the tranquil period play a key role during the crisis. Secondly, causality directions give evidence of the major influence of the South Korean crisis which seems to prevail on investors to reassess the whole region.
