The foremost aim of the present study was the development of a tool to detect daily deforestation in the Amazon rainforest, using satellite images from the MODIS/TERRA sensor and Artificial Neural Networks. The developed tool provides parameterization of the configuration for the neural network training to enable us to select the best neural architecture to address the problem. The tool makes use of confusion matrices to determine the degree of success of the network. A spectrum-temporal analysis of the study area was done on 57 images from May 20 to July 15, 2003 using the trained neural network. The analysis enabled verification of quality of the implemented neural network classification and also aided in understanding the dynamics of deforestation in the Amazon rainforest, thereby highlighting the vast potential of neural networks for image classification. However, the complex task of detection of predatory actions at the beginning, i.e., generation of consistent alarms, instead of false alarms has not been solved yet. Thus, the present article provides a theoretical basis and elaboration of practical use of neural networks and satellite images to combat illegal deforestation.

Forest of the world is under serious threat owing to deforestation and fire. It is vital to understand the extent and pattern of deforestation to devise strategies before the problem results in massive environmental impact. On top of this identifying the degree of susceptibility of the forest to forest fire is also plays the same role. However, determining the extent and pattern of deforestation and identifying the level of susceptibility of the forest to fire is challenging by traditional approach. Thus, this book provides a technique to determine the extent, pattern and rate of deforestation. Moreover, it provides a method to analyze the degree susceptibility of the forest to forest fire. Although fire is one of the devastating factors for most vegetation,surprisingly it creates favorable condition for ericaceous vegetation of Ethiopian highland. The analysis in this book provides help to utilize GIS and remote sensing for forest fire susceptibility analysis, cover change detection and land cover pattern analysis. Particularly it offers useful information to professionals in GIS and remote sensing ,forestry, and agriculture fields.

Implications of Deforestation to the Livelihood...

This manuscript is a MSc. Dissertation which highlights the implications of deforestation to the livelihoods of local communities in Kasulu District, Tanzania. It presents spatial and temporal forest cover changes, underlying and immediate causes of deforestation, and impacts of deforestation to socio-economic activities, and evaluate forest conservation measures. Field surveys were conducted using both qualitative and quantitative approaches. Remote sensing and GIS analysis show that Kasulu district has been facing deforestation since 1980s, and there was no uniform forest cover from 1986 to 2009 in the study area. Deforestation has been largely attributed to rapid population growth including large influxes of refugees, and poor implementation of forest conservation and management strategies, agricultural expansion, and poverty. As a result, deforestation has been undermining economic, social and natural resources base. This study recommended awareness creation,promoting aforestation, reforestation and agro-forestry, participatory forest management strategies, and promoting income generating activities to reduce pressure on forest resources.

A Tale of Two Communities
50,40 € *
ggf. zzgl. Versand

The depletion of forests in developing countries hasbeen of increasing concern to policymakers over thepast 25 years. As society searches for ways toaddress climate change, deforestation has become acentral part of this discussion. This book focuses onthe causes of deforestation in common propertyforests in Mexico, presenting a detailed, empiricaleconomic analysis of forest loss in Mexico between1994 and 2000. Understanding the driving forcesbehind deforestation, and pinpointing the location offorests at risk provides crucial information fordeveloping effective forest protection policy. Theanalysis in the first part of this book provides thefoundation for a discussion of potential and actualpolicies to address deforestation in Mexico. Althoughthe data come from a particular place and point intime, the lessons learned contribute to ourunderstanding of resource depletion and degradationin a variety of contexts.

The purpose of this book is to summarize and analyze the competing positions about the consequences of continued deforestation in the Brazilian Amazon as these positions are presented in scholarly books on the subject published between 2000 and 2010. The analysis of the competing positions on the consequences of deforestation in the Brazilian Amazon focuses on and is guided by the search for answers to two critical questions: Which groups of people in the world benefit from the ways in which the consequences of deforestation in the Brazilian Amazon are presented in the books reviewed, and which groups of people are neglected or harmed by the ways in which this issue has been presented? Which assumptions about the consequences of deforestation in the Brazilian Amazon have been accepted as truth and have not been questioned by the authors of the books? This book is a critical study of ideological bias and how ideological bias affects the contemporary debate about the consequences of deforestation in the Brazilian Amazon.
