Última Economic valuation of the Emas waterfall, Mogi-Guaçu River, SP, Brazil Anais da ABC (AABC) Peixer,Janice; Giacomini,Henrique C.; Petrere Jr,Miguel. The Emas waterfall in Mogi-Guaçu River is regionally recognized as an important fishing spot and touristic place. The first reports of the professional and sport fishing there date back from the 30's, which is the same period when the tourism took place. The present paper provides an environmental valuation of this place and an assessment of the differences among the major groups of people using the area. During 2006 we interviewed 33 professional fishers, 107 sport fishers, 45 tourists and 103 excursionists in order to estimate the Willingness to Pay (WTP) for each category and to analyze the influence of socioeconomic factors by means of logistic regressions and ANCOVAs. The WTP of professional fisher was significantly influenced by age and education,...

Spittlebugs are the most damaging pasture pests in tropical America where extensive monocultures of Brachiaria decumbens cv. Basilisk have favoured the buildup of spittlebug populations. Under severe spittlebug attack, the entire above-ground portion of the plant appears dry and dead, reducing the stocking rates of damaged pastures. Host plant resistance is a low-cost method of controlling spittlebugs, which farmers can easily adopt. High level of spittlebug resistance is found in the cultivar B. brizantha cv. Marandu, but it requires more fertile soils. A Brachiaria germplasm provided by the International Center for Tropical Agriculture and available at the National Center for Beef Cattle Research (CNPGC) has been screened for spittlebug resistance.
