Growth Models For Tropical Forests: A Synthesis Of Models And Methods, Jerome K. Vanclay
Growth Models For Tropical Forests: A Synthesis Of Models And Methods, Jerome K. Vanclay
Professor Jerome K Vanclay
Tropical forests may have many species, indeterminate ages, and a wide range of growth habits and stem sizes and thus require special modeling techniques. But technique contributes only part of model quality, and much depends on the calibration data and access to the model. Whole stand models have limited utility in these forests, as it is hard to describe the forest adequately with few stand-level variables. Stand table projection and matrix models may be useful where summarized data are available and computer resources are limited, but the many classes required detract from the method. Tree list models offer greater flexibility, …
Why Model Landscapes At The Level Of Households And Fields?, Jerome K. Vanclay
Why Model Landscapes At The Level Of Households And Fields?, Jerome K. Vanclay
Professor Jerome K Vanclay
Sustainable resource management relies upon many disciplines and deals with complex interactions at the landscape scale. Many of the issues at the landscape scale arise from decisions taken at the household level and affect land use in fields and in small patches of forest. Spatially-explicit modelling of these units is desirable because it enables rigorous testing of model predictions, and thus of underlying propositions. The greatest insights may be obtained by participatory modelling of these processes as we understand them. Despite this, few models simulate dynamics at the household and field level. FLORES, the Forest Land Oriented Resource Envisioning System, …
