| The heterogeneous nature of even small communities has been acknowledged, yet how such heterogeneity is reflected in local ecological knowledge (LEK) among groups of resource users in a community is poorly studied. This study examines the ecological knowledge held by fisher groups using differing gear and operating in different subsystems of a coastal seascape in south Kenya. Knowledge is compared to that of nonfishing groups and is analyzed with respect to the scales of ecological processes and disturbances affecting the ecosystem to identify mismatches of scale between local knowledge and ecological processes, as well as points of convergence upon which emerging scientific and local community information exchange can build and develop. Results reveal... |

| Landowner classifications based on their objectives have been used to describe the heterogeneous group of landowners. As the accurate information on landowners preferences is essential in policy planning and evaluation of the effects of various policy instruments, there is a need to develop feasible methods for classifying land owners. In this study we apply objective based classification to farmland owners using the data of Finnish farmland owners. We compare two classification methods, traditional cluster analysis and latent class analysis, in terms of their criterion validity. The comparison of criterion validity, consisting from convergent, concurrent, discriminant and predictive components of validity, revealed that latent class analysis was superior... |
