Les For Ts Du Bassin Du Congo

Starting in 1994, Cameroon introduced regulatory and market-based reforms to regulate access to its rainforests, balance public and private interests in those forests, and integrate wider economic, cultural, and environmental perspectives of the value of forests. Based on historical data and extensive interviews, this report concludes that the reforms brought order over the most aggressively competing interests and started to address deeper social and environmental issues, but a significant unfinished agenda remains. On the positive side, information on the boundaries, ownership, use rights, and management of Cameroon s rainforests has become available for public scrutiny, along with information on detection and prosecution of illegal activities. Better and better known rules of the game have improved forest governance and collaboration between forest institutions and civil society. More than 60 percent of Cameroon s rainforests are under management systems that emphasize sustainability. Illegal logging has declined sharply managed parks and production forests, although it persists in rural areas. The restructured forest industry has adopted internationally recognized management practices that have started to align logging with the forest s capacity to regenerate. Cameroon has established rules to preserve customary rights to forests, and community forests have progressed despite unanticipated challenges. Yet further reform is needed. Deeper recognition of the customary rights of all people who depend on Cameroon s forests, regardless of ethnicity, is vital. Timber and nontimber forest products like medicinal plants and bush meat remain subject to illegal exploitation outside state forests. Cameroon needs qualified eco-investors to sustain conservation and diminish reliance on timber production. Community involvement in the management of all types of forests should expand further. Great attention to local markets and small firms will strengthen forest governance and the forest industry in important ways. Rewarding responsible corporate behavior with more lenient bank guarantees and tax incentives may prove as important for conserving forests as punishing corporate misbehavior.

This book summarizes the geomorphology, geology, geochronology, geophysics and mineral resources of the Congo Basin, one of the world’s most enigmatic and poorly understood major intra-continental sedimentary basins, and its flanking areas of Central Africa. It provides an up to date analysis of the large region’s origin and evolution. The book’s nineteen chapters take the reader through the entire basement history, as well as the Basin’s ca. 700 million years of cover sequences. Starting from its Archean cratons and Proterozoic mobile belts, and proceeding through the Phanerozoic sequences, including the most recent Cenozoic successions, the book also explores the present drainage systems and the subtle but complex topography of the Congo Basin. It also presents and evaluates new basin models and related dynamic processes, as well as revised correlation schemes with its Gondwana counterparts in South America, all of which provide key insights into its rich diamond deposits and other mineral wealth, which are documented in the final chapters. A specific feature of this book is its synthesis, performed by teams of active experts, of a vast amount of geoscientific data previously only recorded in research reports, company reports, survey bulletins, and scattered journal articles and books. The sheer size of the Congo Basin (ca.1.8 million km2, or just under half the area of the EU) and Central Africa (some 7 million km2, or more than 70% of the area of the USA) will make this a sought-after source of information and inspiration on this unique region.

Human well-being and the prerequisite sustainable environmental management are currently at stake, reaching a bottleneck when trying to cope with (i) the ever-growing world population, (ii) the constantly increasing need for natural resources (and the subsequent overexploitation of species, habitats, ecosystems, and landscapes) and (iii) the documented and on-going impacts of climate change. By this, the role of conservation and management practices for the environment is characterized as a crucial and top issue and should deal with (a) promoting best practices from the local to the global level, (b) identifying spatial and temporal knowledge gaps, (c) multidisciplinary aspects for sustainable management practices, (d) identifying and interpreting the role of stakeholders and socio-economic parameters in the decision-making process, and (e) methods and practices to integrate the concept of ecosystem services into natural capital assessment and accounting, conservation and management strategies. Modern literature highlights that land use change and prioritization, the restoration of natural areas and cultural landscape identification and maintenance, should be considered at the top of the scientific and policy agenda, as well as at the epicenter of novel awareness-raising strategies for the environment in the near future.

This calendar, with illustrations, is a reference service focusing on multilateral treaties concluded by more than two parties. It covers a period of almost 350 years of multilateral diplomacy, from the Peace of Westphalia of 1648 to the end of 1995. It lists chronologically all multilateral treaties concluded during that period, provides information on the location of their printed text in various collections (with parallel citations), adds data on duration, depository arrangements, & status, & provides extensive notes on their amendment, modification, extension, termination, & other details (with related references). It ends with appendices & a detailed index.
