Opis

Land in the tropics and sub tropics occupy approximately 40 percent of the Earth's surface and is currently home to a a large portion of the world's population. This book provides a detail ed scientific account of the current state and condition of land change in the Tropics. The main themes of tropical land change science include not only extensification and intensifi cation, butal so diversification and co mpetition for land; resilience of land systems; the multiple roles of institutions, markets, societies, and individu als; andth e effects of decisions made at manifold spatial, temporal, and organizational scales in influencing land change. These themes together with issues such as frontier settleme nt, dynamics of plant invasions and other changes in environmental qualitya ssociated with alternate land uses clearly demonstrate the importanceof an integrateda nd interdisciplinary understanding of socio economic and human systems aswell as environ mental systems. This book takes such a coupled approach to human and natural systems and investigates land change as anexe mplar oft he funda mental interdependence of society, economy, and environment. Development of methodologies required for achieving a more integrated and interdisciplinary understanding of land change in coupled natural and human systems are an important effort in the international land change sci ence community. This book addresses and explores manyof t hese meth odologies, provi ding detailed case studies that demonstrate the importance of strong methodologies.

Wendy Jepson is an Assistant Professor in the Department of Geography at Texas A&M University. She earned her doctorate from the Department of Geography at the University of California, Los Angeles in 2003. Her research focuses on land-use and land-cover change along South America’s modern agricultural frontier, particularly the savannas and dry tropical forests, and the transformation of landscapes in the Lower Rio Grande Valley, Texas. She also examines the relationship between water, society, and equity on the US-Mexico Border. She serves on the editorial board of GeoJournal: An International Journal of Geography

Land use and land-cover change research over the past decade has focused mainly on contemporary primary land-cover conversions in the tropics and sub-tropics, with considerable resources dedicated to the explanation and prediction of tropical deforestation and often ignoring the dynamism in the world’s agro-pastoral landscapes. This collection integrates cutting-edge research in the social, biogeophysical, and geographical information sciences to understand the human and environmental dynamics that change the type, magnitude and location of land uses and land covers in the changing countryside. Our contributors are from across the globe and draw on diverse empirical pan-tropical case studies and disciplinary influences. The research reported examines land-use and land-cover change in Bolivia, Brazil, China, Colombia, Côte d’Ivoire, India, Malawi, Mexico, Pakistan, Peru, Senegal and Thailand. Each chapter in this book advances one of three themes: (i) adaptations and change in settled agricultural zones, (ii) agricultural intensification, and (iii) markets and institutions. This book describes the monitoring of land-cover changes, explains the processes through which land is altered, and describes the development of spatially-explicit models to predict land change. This book illustrates how practitioners have integrated knowledge from the three scientific realms - social, biophysical, and GIScience - that underpin land-change science.
