Nessa obra, foram analisadas as formações vegetais em Angola levando em consideração dois níveis de classificação, o de fitofisionomia (N1) e o de uso e cobertura da terra (N2). As áreas representadas por vegetação nativa como florestas, savanas e formações de estepes apresentaram maiores áreas se comparadas com as restantes classes como solo exposto, água e deserto no nível N1, e dunas arenosas, corpos d ́água e agricultura no nível N2. As estações chuvosas apresentaram influência tanto na Evapotranspiração normal como na duração da estação do crescimento da vegetação, mas com uma alta variabilidade espaço-temporal. No entanto, as classes de vegetação nativa tanto em nível N1 como em nível N2 mostraram uma resposta do início do aumento do verdor mais rápido após o início das chuvas, quando comparadas com as outras classes de vegetação antropizadas. Portanto, a partir deste estudo é possível entender como se dá a distribuição espacial da vegetação em Angola e entender como diversos fatores ambientais contribuem para a sua explicação.
This volume comprises an outstanding variety of chapters on Earth Observation based time series analyses, undertaken to reveal past and current land surface dynamics for large areas. What exactly are time series of Earth Observation data? Which sensors are available to generate real time series? How can they be processed to reveal their valuable hidden information? Which challenges are encountered on the way and which pre-processing is needed? And last but not least: which processes can be observed? How are large regions of our planet changing over time and which dynamics and trends are visible? These and many other questions are answered within this book “Remote Sensing Time Series Analys...
Environmental Soil Physics is a completely updated and modified edition of the Daniel Hillels previous, successful books, Introduction to Soil Physics and Fundamentals of Soil Physics. Hillel is a Pulitzer Prize-winning author, one of the true leaders in the field of environmental sciences. The new version includes a chapter and problems on computational techniques, addresses current environmental concerns and trends. - Updates and expands the scope of Hillel's prior works, Fundamentals of Soil Physics (1980)and Applications of Soil Physics (1980) - Explores the wide range of interactions among the phases in the soil and the dynamic interconnections of the soil with the subterranean and atmospheric domains - Draws attention to historical and contemporary issues concerning the human management of soil and water resources - Directs readers toward solution of practical problems in terrestrial ecology, field-scale hydrology, agronomy, and civil engineering - Incorporates contributions by leading scientists in the areas of spatial variability, soil remediation, and the inclusion of land-surface processes in global climate models
This study explores policies, incentives and options for the rural poor who depend on the miombo woodlands of Southern Africa. Because of the important role of forests as social safety nets, planners must keep in mind the cost of deforestation and degradation to rural populations.
Using original sources--such as newspaper articles, silent movies, letters, autobiographies, and interviews--Ilaria Serra depicts a large tapestry of images that accompanied mass Italian migration to the U.S. at the turn of the twentieth century. She chooses to translate the Italian concept of immaginario with the Latin imago that felicitously blends the double English translation of the word as "imagery" and "imaginary." Imago is a complex knot of collective representations of the immigrant subject, a mental production that finds concrete expression; impalpable, yet real. The "imagined immigrant" walks alongside the real one in flesh and rags.
