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...

Life table

Model
The life table model is one of the type of survival analysis which pertains to "time to event". The information that were accumulated throughout the study is one of the advatage of this method.This often used in demographics and epidemiology but can also be used on agricultural economics. Sperling and Loevinsohn (1992) used this method in analyzing varietal diffusion for beans in which the main objective is to know howm nay technology adopters remains after a time period.

Living in a network of scaling cities and finite resources

Case
This is a placeholder case for the model of the same name. A quantitative model of a multiple consumer-resource system with multiple consumer-consumer and consumer-resource couplings. Consumers are "cities" that display non-linear scaling behaviors and inter-city migration.

Living in a network of scaling cities and finite resources

Model
A modified Lotka-Volterra system in which multiple consumers and resource systems are connected by both consumer-consumer and consumer-resource links. Consumers represent cities, and thus exhibit nonlinear scaling behaviors as population increases w.r.t. harvest rate and harvest conversion efficiency. Populations can also migrate between cities along a welfare-dependent gradient.Analysis of the model for a simple dyadic network reveals that the basic Lotka-Volterra formulation can lead to...

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....
