Comparative research looks at two or more similar groups, individuals, or conditions by comparing them. This comparison often focuses on a few specific characteristics. This method can also be used to compare the same group, condition, or individual over time (also called longitudinal comparison). Comparisons may be qualitative or quantitative.
The use of comparative research in resource management can be applied in many ways. Managers can compare certain characteristics of one area to another area to determine how well a management strategy is working. For example a manager could compare two neighboring Marine Protected Areas - one in which artisanal fishing is regulated and another where no regulations are in place.
