Citrus variegated chlorosis (CVC) is one of the most important diseases for Brazilian citricultureIt is caused by Xylella fastidiosa subsp. pauca, a xylem limited, cycadelid and budwood transmitted bacterium. In Bahia, the second most important citrus region in Brazil, CVC has been present since 1997. Our objectives were to characterize the regional spatial pattern of CVC and to establish a relationship between epidemiological variables and horticultural practices, as well as to evaluate whether control measures used so far have been effective and, based on that, to conceive suitable control measures. A series of surveys were performed in two regions of Bahia State (Recôncavo Baiano and Litoral Norte), along with a survey of horticultural and control practices associated with sampled groves. CVC was restricted to Litoral Norte region, especially to three municipalities along the border between Bahia and Sergipe States.The mean CVC incidence in these municipalities followed a gradient, higher in the countryside and decreasing along the coast. Presence and dissemination of CVC was related to poor nursery practices, a massive use of a susceptible orange variety, and an extreme concentration of orange groves in high incidence municipalities, as well as to the absence of specific CVC control. Considering that CVC was not found in Recôncavo Baiano, this region could be considered a "CVC free zone" by the local government. |

Human activities pose a major threat to tropical forest biodiversity and ecosystem serv-ices. Although the impacts of deforestation are well studied, multiple land-use andland-cover transitions (LULCTs) occur in tropical landscapes, and we do not knowhow LULCTs differ in their rates or impacts on key ecosystem components. Here, wequantified the impacts of 18 LULCTs on three ecosystem components (biodiversity,carbon, and soil), based on 18 variables collected from 310 sites in the BrazilianAmazon. Across all LULCTs, biodiversity was the most affected ecosystem component,followed by carbon stocks, but the magnitude of change differed widely amongLULCTs and individual variables. Forest clearance for pasture was the most prevalentand high-impact transition, but we also identified other LULCTs with high impact butlower prevalence (e.g., forest to agriculture). Our study demonstrates the importanceof considering multiple ecosystem components and LULCTs to understand the conse-quences of human activities in tropical landscapes |
