Valuing Agroforestry Systems Methods and Applications
Agroforestry, the purposeful growing of trees and crops in interacting combinations, began to attain prominence in the late 1970s. when the international scientific community embraced its potentials in the tropics and recognized it as a practice in search of science. During the 1990s the relevance of agroforestry for solving problems related to deterioration of family farms, increased soil eros...
متن کاملApplications of GIS in Forestry: A Review
In fact, the development of a fully operational GIS for forest management will likely incorporate each activity as two distinct stages in its development (see Crain and MacDonald 1983, Jordan and Erdle 1990). For example, spatial data input, editing, and simple maps characterize the inventory and monitoring stage. In the modeling stage, overlays, reclassifications and suitability analyses are i...
متن کاملForestry applications of ground-penetrating radar
Ground-penetrating radar (GPR) is a geophysical and close-range remote sensing technique based on the use of radar pulses to obtain cross-section images of underground features. This method is characterized by the transmission of an electromagnetic short length pulse (1-2 ns), presenting a centre frequency ranging from 10 MHz to 2.5 GHz. The principles of GPR operation are based on the ability ...
متن کامل3D Point clouds for forestry applications
This article gives an overview of the state of the art 3D data acquisition systems (i. e. airborne laser scanning and digital aerial cameras) and the derivation of forestry related information from the derived 3D points clouds. The described examples are focusing on forest area delineation, growing stock and biomass estimation, forest growth assessment, forest road extraction as well as its cha...
متن کاملMeteorology and Agroforestry Meteorology and Agroforestry
The physical environment affects and interacts with agroforestry systems through tree and crop growth, animal performance, management operations and interactions between the tree/shrub and non-tree components (abbreviated to tree/crop interactions). Interactions take place mainly through the media of microclimate, soil moisture and soil. They may have beneficial or adverse effects, for tree and...
