Available in PDF, EPUB and Kindle. Book excerpt: Mankind has evolved both genetically and culturally to become a most successful and dominant species. But we are now so numerous and our technology is so p- erful that we are having major effects on the planet, its environment, and the b- sphere. For some years prophets have warned of the possible detrimental consequences of our activities, such as pollution, deforestation, and overfishing, and recently it has become clear that we are even changing the atmosphere (e. g. ozone, carbon dioxide). This is worrying since the planet’s life systems are involved and dependent on its functioning. Current climate change – global w arming – is one recognised consequence of this larger problem. To face this major challenge, we will need the research and advice of many disciplines – Physics, Chemistry, Earth Sciences, Biology, and Sociology – and particularly the commitment of wise politicians such as US Senator Al Gore. An important aspect of this global problem that has been researched for several decades is the loss of species and the impoverishment of our ecosystems, and hence their ability to sustain themselves, and more particularly us! Through evolutionary time new species have been generated and some have gone extinct. Such extinction and regeneration are moulded by changes in the earth’s crust, atmosphere, and resultant climate. Some extinctions have been massive, particularly those asso- ated with catastrophic meteoric impacts like the end of the Cretaceous Period 65Mya.

Book excerpt: The 2010 State of the Forest report (SOF) benefited from financial support from the European Union, the United States, Germany, France and UNESCO. It represents the collaborative effort of over 100 individuals from a diversity of institutions and the forestry administrations of the Central African countries. The SOF process began with the selection and definition of indicators relevant to monitoring the state of forests in Central Africa. The indicators are structured around three thematic areas: (i) forest cover; (ii) management of production forests; and (iii) conservation and biodiversity. They are presented in a hierarchical structure at the regional, national and management unit (i.e. logging concessions and protected areas) levels. The indicators were vetted by a representative panel of stakeholders of forest management in Central Africa. The indicators are used to guide an annual data collection process carried out between April and August by national groups of four to ten individuals working within the forestry administrations. The data reported on in the 2010 SOF were primarily collected in 2009 and 2010. Results were validated in national workshops attended by government officials as well as representatives of environmental NGOs, the private sector and development projects. The data provided an important basis for the authors of the 11 chapters of the 2010 SOF, which were under the coordination of a scientific committee of international renown. A final workshop was held 29-30 March, 2011 in Douala to review a draft report. Following amendments based on comments from a wide audience of experts the final layout was completed.

Download or read book Cameroon written by Boniface Essama-Nssah and published by World Bank Publications. This book was released on 2000-01-01 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This country case study, part of the Operations Evaluation Department (OED) A Review of the 1991 World Bank Forest Strategy and Its Implementation, evaluates World Bank operations in Cameroon for their consistency with the strategy. The strategic aspects of those operations are judged here on their relevance, effectiveness, efficiency, institutional development, and sustainability. The fundamental objective of the forest policy reform in Cameroon was to establish a transparent, equitable, and sustainable management system for forest resources. The outcome of the reform process was limited, for four reasons. First, the government of Cameroon lacked genuine commitment and the capacity to carry out the reform. Second, key actors in the reform process (particularly foreign logging companies and the parliament) chose to oppose it. Third, partners such as the World Bank failed to devise an implementation strategy compatible with the underlying dynamics of political and socioeconomic changes in Cameroon. Finally, while Cameroon's forest policy is well codified in documents, it is poorly implemented. Although the reforms have led to increased tax revenues and increased the share of GDP attributable to the forest sector, the structural underpinnings of the sector have been little affected. Government agencies in the sector continue to be weak. The international logging companies that dominate the sector continue to have a free hand in the development and use of the forest resources of Cameroon. Local communities were left out of the reform process, despite the declared objective to include them in forest resource management. Overall, the interventions of the Bank inside and outside the forest sector in Cameroon were relevant to its strategic objectives, but they were neither efficacious nor efficient. Because of weak institutional development, the achievements are unlikely to be sustained. The Bank should focus its future reform efforts in Cameroon on the collection and dissemination of relevant and reliable information, working with a larger set of stakeholders, and using more Cameroonian expertise to gain local perspective and build capacity. The success of such an approach hinges on government commitment and the cooperation of other donor countries, including those with timber interests in Cameroon.

Download or read book Agroclimatology written by Jerry L. Hatfield and published by John Wiley & Sons. This book was released on 2020-01-22 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: Can we unlock resilience to climate stress by better understanding linkages between the environment and biological systems? Agroclimatology allows us to explore how different processes determine plant response to climate and how climate drives the distribution of crops and their productivity. Editors Jerry L. Hatfield, Mannava V.K. Sivakumar, and John H. Prueger have taken a comprehensive view of agroclimatology to assist and challenge researchers in this important area of study. Major themes include: principles of energy exchange and climatology, understanding climate change and agriculture, linkages of specific biological systems to climatology, the context of pests and diseases, methods of agroclimatology, and the application of agroclimatic principles to problem-solving in agriculture.

Download or read book Recreational Hunting Conservation and Rural Livelihoods written by Barney Dickson and published by John Wiley & Sons. This book was released on 2009-01-22 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recreational hunting has long been a controversial issue. Is it a threat to biodiversity or can it be a tool for conservation, giving value to species and habitats that might otherwise be lost? Are the moral objections to hunting for pleasure well founded? Does recreational hunting support rural livelihoods in developing countries, or are these benefits exaggerated by proponents? For the first time, this book addresses many of the issues that are fundamental to an understanding of the real role of recreational hunting in conservation and rural development. It examines the key issues, asks the difficult questions, and seeks to present the answers to guide policy. Where the answers are not available, it highlights gaps in our knowledge and lays out the research agenda for the next decade.

Download or read book The African Roots of Marijuana written by Chris S. Duvall and published by Duke University Press. This book was released on 2019-05-09 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: After arriving from South Asia approximately a thousand years ago, cannabis quickly spread throughout the African continent. European accounts of cannabis in Africa—often fictionalized and reliant upon racial stereotypes—shaped widespread myths about the plant and were used to depict the continent as a cultural backwater and Africans as predisposed to drug use. These myths continue to influence contemporary thinking about cannabis. In The African Roots of Marijuana, Chris S. Duvall corrects common misconceptions while providing an authoritative history of cannabis as it flowed into, throughout, and out of Africa. Duvall shows how preexisting smoking cultures in Africa transformed the plant into a fast-acting and easily dosed drug and how it later became linked with global capitalism and the slave trade. People often used cannabis to cope with oppressive working conditions under colonialism, as a recreational drug, and in religious and political movements. This expansive look at Africa's importance to the development of human knowledge about marijuana will challenge everything readers thought they knew about one of the world's most ubiquitous plants.
