DOWNLOAD EBOOKThe United Nations has declared 2018-2028 as the International Decade for Action on Water for Sustainable Development. This is a timely designation. In an increasingly thirsty world, the subject of forest-water interactions is of critical importance to the achievement of sustainability goals. The central underlying tenet of this book is that the hydrologic community can conduct better science and make a more meaningful impact to the world’s water crisis if scientists are: (1) better equipped to utilize new methods and harness big data from either or both high-frequency sensors and long-term research watersheds; and (2) aware of new developments in our process-based understanding of the hydrological cycle in both natural and urban settings. Accordingly, this forward-looking book delves into forest-water interactions from multiple methodological, statistical, and process-based perspectives (with some chapters featuring data sets and open-source R code), concluding with a chapter on future forest hydrology under global change. Thus, this book describes the opportunities of convergence in high-frequency sensing, big data, and open source software to catalyze more comprehensive understanding of forest-water interactions. The book will be of interest to researchers, graduate students, and advanced undergraduates in an array of disciplines, including hydrology, forestry, ecology, botany, and environmental engineering.

DOWNLOAD EBOOKDeforestation in the Democratic Republic of the Congo (DRC) is significantly lower than in other heavily forested tropical countries. However, there is increasing concern that this rate is likely to accelerate. Many of those concerned about future deforestation argue that shifting cultivation is the primary driver and that if nothing is done to change the practice, it will cause even more forest loss. This study reviews the evidence in support of these claims. In the first section, we compare the results of the most recent remote sensing-based studies on the rate of change in forest cover and try to explain why and how they differ. We then review the literature on the relationship between agriculture and deforestation in the DRC, with particular attention to the role of shifting cultivation. Finally, we integrate the insights from both the remote sensing studies and the broader literature to arrive at a general picture of the current state of the forest in the DRC and the risks for its future. Overall, we find that while there is substantial variation in the recent deforestation estimates for the DRC depending on definitions, methods and approaches, some deforestation is taking place albeit at a slower rate than in the rest of the tropics. This deforestation is concentrated in Kinshasa and Bas-Congo provinces, in the eastern DRC and around medium-sized cities along the Congo River. Agriculture appears to be the main driver of deforestation and its impact will likely increase as the countrys population grows. While some researchers argue that this presents a real threat to the future of the DRCs forests, there is a lack of strong evidence to show the magnitude of this threat. If the impact continues to be felt mainly in the areas where it is currently taking place, the overall ensuing deforestation may not be very extensive. While the local impacts may be real, given the vast size of the DRC and the location of its large tracts of forests, there is a strong possibility that the overall biodiversity and carbon impacts of such deforestation will be limited.

DOWNLOAD EBOOKSince 2000 and the implementation of China’s ‘going abroad’ policy, mainland Chinese state-owned and private companies have significantly increased their interests in the resources and investment opportunities of the Congo Basin, bringing new opportunities as well as potential social and environmental costs. This report is a synthesis of some main findings of preliminary scoping studies conducted by CIFOR and partners in Cameroon, Democratic Republic of Congo and Gabon. It focuses on how Chinese trade and investment in the forestry, mining and agricultural sectors might relate to effects on forests and forest-dependent communities in the region. All studies were conducted under the CIFOR project ‘Chinese trade and investment in Africa: Assessing and governing trade-offs to national economies, local livelihoods and forest ecosystems’, initiated in 2010. The scoping studies yielded useful results, including an increased understanding of the main trends in natural resources trade between the target countries and China, and the major land-based productive sectors targeted by Chinese investors. The studies also considered the role of national agencies tasked with promoting investment and overseeing corporate adherence to environmental and social requirements, and provided a better understanding of the informal processes surrounding investment and acquisition of land and other resources.

DOWNLOAD EBOOKGlobal environmental change (GEC) represents an immediate and unprecedented threat to the food security of hundreds of millions of people, especially those who depend on small-scale agriculture for their livelihoods. As this book shows, at the same time, agriculture and related activities also contribute to GEC by, for example, intensifying greenhouse gas emissions and altering the land surface. Responses aimed at adapting to GEC may have negative consequences for food security, just as measures taken to increase food security may exacerbate GEC. The authors show that this complex and dynamic relationship between GEC and food security is also influenced by additional factors; food systems are heavily influenced by socioeconomic conditions, which in turn are affected by multiple processes such as macro-level economic policies, political conflicts and other important drivers. The book provides a major, accessible synthesis of the current state of knowledge and thinking on the relationships between GEC and food security. Most other books addressing the subject concentrate on the links between climate change and agricultural production, and do not extend to an analysis of the wider food system which underpins food security; this book addresses the broader issues, based on a novel food system concept and stressing the need for actions at a regional, rather than just an international or local, level. It reviews new thinking which has emerged over the last decade, analyses research methods for stakeholder engagement and for undertaking studies at the regional level, and looks forward by reviewing a number of emerging 'hot topics' in the food security-GEC debate which help set new agendas for the research community at large.

DOWNLOAD EBOOKMineral deposits are not only primary sources of wealth generation, but also act as windows through which to view the evolution and interrelationships of the Earth system. Deposits formed throughout the last 3.8 billion years of the Earth's history preserve key evidence with which to test fundamental questions about the evolution of the Earth. These include: the nature of early magmatic and tectonic processes, supercontinent reconstructions, the state of the atmosphere and hydrosphere with time, and the emergence and development of life. The interlinking processes that form mineral deposits have always sat at the heart of the Earth system and the potential for using deposits as tools to understand that evolving system over geological time is increasingly recognized. This volume contains research aimed both at understanding the origins of mineral deposits and at using mineral deposits as tools to explore different long-term Earth processes.
