Progress on resilience was monitored using indicators created to track the performance of the system, actors and institutions, which facilitated fulfilment of one of the most important requirements under this model: continuous review of the implementation of interventions to ensure that they contributed to producing the expected results. This kind of process of iteration helps to identify problems as they arise and to ensure the incorporation of new information so as to improve project implementation, which is particularly important as new information on climate impacts is continuously evolving. In Sri Lanka, for example, while the introduction of high-yielding hybrid varieties of rice seeds had initially had a beneficial effect on yields, support for their use led to an undermining of the ability of farmers to adapt to changing conditions.
