Direct drivers of deforestation in Amazon countries Cattle ranching Cattle ranching is the leading cause of deforestation in the Amazon rainforest. In Brazil, this has been the case since at least the 1970s: government figures attributed 38 percent of deforestation from 1966-1975 to large-scale cattle ranching.
The sampling frequency or sampling rate, fs, is the average number of samples obtained in one second (samples per second), thus fs = 1/T. Reconstructing a continuous function from samples is done by interpolation algorithms.
This sampling is carried out when the parameters of the entire population are not required. This type of sampling is easy, cheap and quick but not accurate. Non-probability sampling can be classified into 5 types. Convenience sampling: In this sampling subjects are selected on the convenience of the researcher.
