Utilização de imagens multispectrais na avaliação das ocorrências de queimadas e incêndios florestais na Terra Indígena Krahôlandia (2003-2014). As ações humanas alteram as ocorrências naturais dos incêndios e queimadas. Os povos indígenas, quando da ocupação do Cerrado, provavelmente usavam o fogo para manipular a paisagem e os seus recursos em várias épocas do ano. Este trabalho teve por objetivo analisar e mapear a distribuição espacial de áreas queimadas na Terra Indígena Krahôlandia, no período de 2003 a 2014, utilizando ferramentas de sensoriamento remoto e SIG. Nos 12 anos avaliados, a área queimada total foi de 1.516.872,51 ha, que representa 4,94 vezes a área total da TI Krahôlandia (306.871,02 ha). A média anual de área queimada foi de 126.406,04 ha (41,19%) com o ano da maior área queimada com 185,297 ha (60,4%) e o ano da área menor com 71,764 ha (23,4%). Houve 29.764 ha (9,7%) que nunca tinham sido queimadas durante os 12 anos, e 1.693 ha (0,6%) que tinham sido queimados todos os doze anos. Além disso, as áreas que registraram a maior frequência de ocorrência de incêndios e queimadas não foram surpreendentemente aquelas que produziram as maiores áreas queimadas ao longo do período. Os dados de sensoriamento remoto aliados com metodologia empregada conseguiu identificar a frequência de ocorrência de queimadas e incêndios florestais na terra indígena Krahôlandia. |

Brazil is the largest citrus producer in the world, and leprosis is currently considered the main viral disease for the Brazilian citrus industry due to the high costs spent for the chemical control of its vector, the tenuipalpid mite Brevipalpus sp. The global importance of leprosis has significantly increased in the last years, with the northbound spread of the virus to new regions of the American Continent. However, despite the worldwide distribution of its vector, there is no confirmation of the disease outside the Americas. Leprosis is endemic to the main citrus producing areas of Brazil and, even though there are several strategies available for its management, such as pruning of symptomatic branches, reduction of Brevipalpus populations with predaceous mites etc., the control of the disease is fundamentally based on the spray of pesticides after the action threshold for the mite is reached. Recent studies on the epidemiology of leprosis and on virus-vector interactions, however, strongly suggest that growers should take into consideration the presence of the disease ? and not only the vector - in the field for its proper control. Hence, the correct diagnosis of leprosis is essential for its management. Typical symptoms can be easily recognized by experienced personnel in endemic areas. Nevertheless, particularly for new areas, identifying leprosis symptoms may be somewhat challenging. In recent years, however, in addition to the examination of lesions using a transmission electron microscope, other molecular- or serological- based tools have being successfully used to confirm new cases of the disease. This workshop on citrus quarantine pests will bring several aspects on leprosis including a historical view of the disease, its main characteristics, alternatives for its management, its increasing economical importance in Brazil and abroad, and the new data on the search for understanding the interactions amongst the mite vector, the virus, and the plant host.
