I read some articles which conclude Adaptation and Resilience have the same meaning and in some others, adaptation is just one aspect of resilience.i just want to know what features separate these two topics.
Resilience has multiple components including adaptation (microevolutionary change--relies upon heritable changes in genes or gene expression) and phenotypic plasticity (acclimatization--organismal alteration in morphology, physiology etc. that does not require genomic changes for expression of the 'new' phenotype). Separating the relative importance of these two processes to organismal resilience is equally important and challenging.
Adaptation is where you make changes (adapt) to fit with the new circumstances. Resilience is how able you are to cope with the new circumstances.
For instance if your food supply is cut from two loafs per day to one loaf per day, you may be resilient enough to survive. If it is then cut to half a loaf per day you would starve to death unless you adapted by eating cake!
The more you can adapt the more resilient you are.
An important distinction here is that adaptation requires evolutionary change i.e., genetic change, whereas the other aspect of species resilience (acclimation) represents phenotypic plasticity and thus does not require genetic alteration.
Adaptation refers to those crucial actions or plans that a commuinty or household or individual will employ against a current or anticipated impact of climate change whilst resilience refers to the ability to recover (bounce back to the original state before the exposure to shock) from the effect of climate change.
