Droughts, insect infestations, and fires are increasingly common in Mexico’s forests. Communities whose residents manage these forests can develop strategies to protect their forests and ecosystems, which are critical in the fight against climate change. The society forest management strategy check also provide livelihoods and boost economies, scientist explain . In some autochthonous languages, two speech are just not sufficient to convey everything encompassed by the phrase “climate change. ” Alejo López, who says one of the species of Chinantec that is spoken in Mexico’s Oaxaca state, told Mongabay Latam that he refers to climate change with a longer phrase: “ Ni ka li remembered ja lee ee lï ´ mïï hui ´. ” In English, these speech mean, “We keep what we have, and we make happy use of our forest, our water and our air.” The Chinantec folks residing in the Sierra Juárez mountain range in Oaxaca refer to themselves as tsa ju jmí’, which means “people of the past word.” Their tonal language is mostly spoken, but a few years ago, López began to learn its written form. The Chinantec dialect is far from being López’s only area of expertise. Like various of his line in Santiago Comaltepec, Oaxaca, he also understands about trees and community organization. He is the leader of the administrative council of the Union of Zapotec and Chinantec Forestry Communities (UZACHI) . term ago, showing to López, rain was almost continual in the forest. “ It employed to rainstorm for most of the year, but now a lot has changed. Just this year, already, it has almost been a month without rain. That is due to deforestation,” López said. López’s notice of the change in rainfall coincides with scientists’ warnings of the effects of global climate change for some time. One of these effects is the increased intensity of droughts. corresponding to Julián Andrés Velasco Vinasco, who use with the Climate Change and Solar Radiation Group at the racial Autonomous University of Mexico, there is still much to be learned about the specific effects of climate change in Mexico. It is thought that some groups of plants could disappear, “but we do not have detailed information about which species are most susceptible to this phenomenon,” Velasco Vinasco said. Those who live around community forests, like López, have already observed some of the consequences of climate change. The development of infestations In Chinantec, mo´ means “forest,” and ´mah means “tree.” The nature in the Sierra Juárez mountain range in Oaxaca have also facinged senior insects recently, and some of them, like the round-headed pine beetle (Dendroctonus adjunctus) and the “defoliator” (Zdiprino spp.), are considered infestations because of the damage they cause to the trees. “Before, the nasty age was senior marked, and in low temperatures, these infestations declined [in terms of] their population; the nature sustained their vigor,” said Salvador Anta Fonseca, a member of the Mexican civilian Council for Sustainable Forestry (CCMSS) and the senior counselor on forest policy for the organization Environmental Policy and Legislation. Now, with elder prolonged cycle of true temperatures and droughts, the infestations have a greater capacity for growth and, obviously, for affecting the forests.” Manuel Herrera Santiago, technical director of UZACHI, said climate change fosters the growth of the infestations. “ The time of the round-headed pine beetle have shifted; that is very noticeable,” he said. “ It is an infestation that we already have, but right now, with the changes in temperature, the months of incidence of this insect are not as entered as before.” The age to be capable to effectively combat the insect in its larval stage employed to be from January to June, “but now, in those months, there are already adults, or the larvae appear later. The situation is being assessed since it is possible that there is another species of Dendroctonus,” said Laura Jiménez Bautista, technical subdirector of UZACHI. In addition, an infestation by a various insect has emerged to appear in Oaxaca: the defoliator. “ It first appeared in a community, and there are already going to be 20,000 affected hectares [nearly 50,000 acres],” Anta Fonseca said. Herrera Santiago explained the mountainous forests, which had warm conditions in the past, are now facing higher temperatures. The cozy limitation have appeased these infestations. “ The defoliators did not employed to exceed 2,200 bar [about 7,200 feet] above sea level, and now we have them at up to 2,800 meters [about 9,200 feet] above sea level. It is something extraordinary, and people are not formulated to confront an infestation that will appear overnight. This is something that strikes very strongly,” Herrera Santiago said. The insecticides employed to attack the defoliator are made with fungal spores and are dispersed using helicopters above the trees. From the ground, people also scatter them to disrupt the insect’s larval phase. For the communities that own these forests and make sustainable use of them, these threats come with new costs and processes. “ Those insecticides stick in the bodies of the [defoliator] caterpillars. They perforate fiber and kill them. They are not chemical insecticides, because in those forests there are springs, and people drink water from there,” Anta Fonseca, who collaborates closely with these communities, said. Constant vigilance, monitoring and combating the insect — by authorities and experts — are some strategies being used to confront the infestations. Herrera Santiago explained the society are also innovating in their fight against the infestations by using alternative tactics. These include the application of mechanical treatments, like the purification of forested areas, controlled burns, and killing the insects manually. The multiplication of forest firesSince mid-April and early May, smoke from the forest fires in the Sierra Juárez has saturated the air, or gih, as the Chinantec call it. “A melody that is relating the country, and strongly [ affecting] Oaxaca, is forest fires. Right now, we have forest fires, one after the other. We are starting to have 40 fires at the state level simultaneously,” Herrera Santiago said. Enrique Jardel, a researcher and professor at the Department of Ecology and Natural Resources at the University of Guadalajara, said that 2019 had some of the hottest temperatures ever recorded, which has fostered a higher incidence of fires in Mexico. corresponding to Jardel, “The climate is the top factor that controls fire regimes, and what is being observed on a global scale are changes in seasonality. For example, [there are] longer aridity seasons, and this boosts the propagation of fires. In countless cases, ultimate famine for several years create the conditions for the propagation of very severe fires.”
