Avaliação do desmatamento dunar de Chizavane, distrito de Mandlakaze - Gaza

Abstract

Results found in the study area at the beginning of the study were 761 hectares in total, respectively. Not only but also, in a gesture of observing the problem in this area it was noted that from 2009- 2016, the dense vegetation area suffered a deforestation of 57 hectares, the less dense vegetation suffered a deforestation of 71 hectares and the total deforested area was 128 hectares and in the 2009-2016 interval, the average annual deforestation rate was 18.2 hectares. The dense vegetation suffered an average annual rate of 8.2 of change and the less dense vegetation, suffered an average annual rate of 10.1 hectares of change. Projections indicate that there is deforestation of dune vegetation of 18.2 hectares per year, so some structures will be destroyed and may be affected coastal zone. It is recommended that some intervention be made such as lectures to local community, control in the practice of tourism and replacement of native vegetation. With this work, the present work was developed applying the most advanced techniques to determine and propose measures the process that occurs through the destruction of the coastal dunes in the locality of Chizavane district of Mandlakaze province of Gaza, whose main objective was to evaluate the deforestation of dune vegetation in Chizavane district of Mandlakaze Gaza province using satellites images (Google Earth images) in order to contribute to the identification of potential factors related to coastal deforestation in the district, erosion and made analysis of oceanographic agents using historical data being them the temperature, precipitation and through the data of intensity of the wind collected in the national institute of meteorology - Gaza and after analysis, it was verified that the prevailing winds are coming from South and SE with average monthly speeds of 12.6 km / h. During the execution of the work it was found that the destruction of the dunes in Chizavane is a very delicate case, since the dune is visible dunes in disappearance of coastal protection in a state quite advanced of deterioration due to lack of protection walls and roots of exposed trees indicating that in the past they were covered with land, the coastal zone is the boundary region between the dry land and the adjacent sea where the coastal processes interact with the terrestrial processes
