Abstract. Regional economic indicators and incentives for agricultural landowners in the Brazilian Pantanal were explored in order to understand better the observed increases in deforestation for the implantation of cultivated pastures to assist in the extensive management of beef cattle. About 95% of Pantanal lands are privately owned and about 80% are used as extensively managed cattle ranches. The mean size of agricultural property in the Pantanal is increasing, the cattle density and numbers are decreasing, the proportion of land in cultivated pastures is decreasing, but the area is increasing, land and animal wealth is highly concentrated, and the amount and proportion of land in natural pastures is decreasing. Statistical analyses reveal that land and animal wealth, intensification of agricultural effort, human population, natural pastures and location relative to infrastructure and regional markets influence either the magnitude or the proportion of Pantanal lands deforested for the purpose of implanting cultivated pastures or both. A nonlinear link between wealth measures and deforestation was not established. Improving the profitability of forestland should unambiguously improve the likelihood of its continued management as forest and the maintenance of biological diversity. Potential sustainable uses of forested lands and native biological diversity in the Pantanal include the sustainable extraction of forest species, ranching of wild and feral species, and tourism. |

The objective of this study was to evaluate the viability of using transponders for the electronic identification of water buffaloes and compare their efficiency when used in animals of different age groups. Electronic transponders with RFID technology (2.1 × 12.2 mm) were implanted subcutaneously (D0) in the scutiform cartilage. The animals consisted of four groups: CLF-I (17 calves; 2.1 ± 1.9 months), CLF-II (20 calves; 5.1 ± 3.2 months), HFR (20 heifers; 22 ± 4.7 months) and STR (19 steers; 26.6 ± 6.7 months). The animals were kept under pasture grazing, a part of the year in the dryland and a part in the floodplain, and were monitored for up to 350 days. The average time required for individual transponder implant was 49.46 s, while the time required for reading the code was 3.76 s. The older calves required higher time for individual implant (P = 0.0001) and closer approximation of the reader in the D150 (P = 0.0001). The mean read distance was 2.98 cm in D0 and 1.94 cm in D150. The magnitude of the subcutaneous transponder migration was minimal, and was within an area of 17.2 mm2. A slight bleeding was observed in 15.79% of the animals during the implant. A decreasing incidence of edema was observed until D21, with the heifers being more sensitive until that time (P = 0.0099). Considering the results, it is preferred to implant electronic transponders in calves up to two months of age. The physical rate of transponder loss was 1.3% and the loss of functionality was 9.2%. High reading rate was achieved when animals were raised both in dryland (93.9%) and floodplain (97.2%). Thus, the electronic identification of water buffaloes is a technique capable of replacing traditional and rudimentary methods to identify buffaloes and can provide safe identification of animals.
