Land-cover and Forest in Nepal (I)

Case
Between 1978 and 1992 dramatic forest conversion occurred in two adjacent sub-basins of the Kair Khola watershed in the Chitwan District of Nepal. However, the form of conversion differed significantly. In the Kair sub-basin dense forest was most often converted to maize-based agriculture, while in the Shakti sub-basin dense forest most often became degraded forest. This study undertook a village-level investigation of forest governance to determine whether community and institutional...

Loma Alta community forest, western Equador

Case
This paper provides an explanation for the lack of institutions regulating the Loma Alta Forest. The community has not yet created any rules regarding forest use. The members of the community with the biggest economic stake in the forest have no reason to limit their exploitative practices, and thus little demand exists for forest regulation at the local level. The Loma Alta Forest is in danger of being more severely degraded in the near future because of the lack of forestry institutions....

Marine Protected Areas in the Gulf of California, Sonora, Mexico

Case
Marine protected areas remain as one of the most popular tools for the conservation and management of natural resources in marine ecosystems. However, mere establishment of MPAs without the proper design, management, or enforcement tools may give a false sense of security that such MPAs will be enough to sustain marine resources. The Gulf of California (GOC), in Mexico, has received a great deal of attention over the past 20 years as a region where conservation and resource management efforts...

Mathematical Models in Social Ecological Systems

Case
This case is an umbrella to capture a range of models of ecological, social, social-ecological, and other natural systems (e.g. climate).  In addition, there are several models whose main purpose is to demonstrate model visualization features related to a number of famous mathematical models including the Lorenz Model, the discrete logistic, and predator prey models. The Lorenz Model, probably the most famous of all simple models, is the first ever model of a chaotic dynamical system....

Matsigenka agriculture, Manu Biosphere Reserve, Peru

Case
Arable land among the Matsigenka is a public good (Ostrom 2005: 24). At base the Matsigenka do not have institutions that regulate who can access arable land. Anyone who has been incorporated into a community has the right to access arable land. The only requirement before opening up a new field is that people must state their intent. This practice decreases the probability of clearing a plot of land that someone else was planning to clear. In short, use of arable land does not affect the...
