Available in PDF, EPUB and Kindle. Book excerpt: Tropical forests are certainly the fastest shrinking ecosystems on earth. At the same time, they are the least studied habitats on continental earth. For most areas, we even don't have complete inventories for the best-known groups of organisms, such as the angiosperms, not even mentioning less well-known groups. These examples show how many facets of forest biology must be investigated - and how few of them have been studied to date. Even fewer have been explored in a comparative manner in different regions, so that we normally still don't know whether an effect has general or more or less local character. However, these studies also provide a roadmap for future investigations in forest ecosystems.

Download or read book The European Landscape Convention written by Michael Jones and published by Springer Science & Business Media. This book was released on 2011-02-09 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important and insightful book provides, for the first time, a broad presentation of ongoing research into public participation in landscape conservation, management and planning, following the 2000 European Landscape Convention which came into force in 2004. The book examines both the theory of participation and what lessons can be learnt from specific European examples. It explores in what manner and to what extent the provisions for participation in the European Landscape Convention have been followed up and implemented. It also presents and compares different experiences of participation in selected countries from northern, southern, eastern and western Europe, and provides a critical examination of public participation in practice. However, while the book’s focus is necessarily on Europe, many of the conclusions drawn are of global relevance. The book provides a valuable reference for researchers and advanced students in landscape policies and management, as well as for professionals and others interested in land-use planning and environmental management.

Download or read book Desertification: Causes, Impacts and Consequences written by Roy H. Behnke and published by Springer. This book was released on 2015-12-07 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: It now seems incontrovertible (as Alessandra Giannini has demonstrated) that the series of Sahelian droughts that began in the early 1970s were driven by changes in sea surface temperatures and that they were not caused by local land use mismanagement in the Sahel itself. Combined with the apparent re-greening of the Sahel, these findings effectively close a long-standing policy and scientific debate (in which the lead authors of this book participated) on the causes and extent of desertification in the Sahel. The opportunity now presents itself to treat this debate as a historical object lesson in the relationship between science, the formation of public opinion, and international policy-making in the context of climate change. In short, what might the ‘great Sahelian desertification boondoggle’ have to tell us about current attempts to come to grips with climate change?

Download or read book Traditional Forest-Related Knowledge written by John A. Parrotta and published by Springer Science & Business Media. This book was released on 2011-10-14 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploring a topic of vital and ongoing importance, Traditional Forest Knowledge examines the history, current status and trends in the development and application of traditional forest knowledge by local and indigenous communities worldwide. It considers the interplay between traditional beliefs and practices and formal forest science and interrogates the often uneasy relationship between these different knowledge systems. The contents also highlight efforts to conserve and promote traditional forest management practices that balance the environmental, economic and social objectives of forest management. It places these efforts in the context of recent trends towards the devolution of forest management authority in many parts of the world. The book includes regional chapters covering North America, South America, Africa, Europe, Asia and the Australia-Pacific region. As well as relating the general factors mentioned above to these specific areas, these chapters cover issues of special regional significance, such as the importance of traditional knowledge and practices for food security, economic development and cultural identity. Other chapters examine topics ranging from key policy issues to the significant programs of regional and international organisations, and from research ethics and best practices for scientific study of traditional knowledge to the adaptation of traditional forest knowledge to climate change and globalisation.

Download or read book Pastoralism and Socio-technological Transformations in Northern Benin written by Georges Djohy and published by Göttingen University Press. This book was released on 2017 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pastoralists throughout Africa face increasing pressures. In Benin, governmental development policies and programmes in crop farming are changing power relations between herders and farmers to favour the latter. How are the Fulani pastoralists responding to these threats to their existence? Georges Djohy explores the dynamics in local use of natural resources and in inter-ethnic relations resulting from development interventions. He combines the approaches of science and technology studies – looking at the co-construction of society and technology – and political ecology – looking at the power relations shaping the dynamics of economic, environmental and social change – so as to throw light on the forces of marginalisation, adaptation and innovation at work in northern Benin. Having worked there for many years, Djohy has been able to uncover gradual processes of socio-technological change that are happening “behind the scenes” of agricultural development involving mechanisation, herbicide use, tree planting, land registration and natural resource conservation. He reveals how farmers are using these interventions as “weapons” in order to gain more rights over larger areas of land, in other words, to support indigenous land grabbing from herders who had been using the land since decades for grazing. He documents how the Fulani are innovating to ensure their survival, e.g. by using new technologies for transport and communication, developing new strategies of livestock feeding and herd movement, and developing complementary sources of household income. The Fulani are organising themselves from local to national level to provide technological and socio-cultural services, manage conflicts and gain a stronger political voice, e.g. to be able to achieve demarcation of corridors for moving livestock through cultivated areas. They even use non-functioning mini-dairies – another example of development intervention – to demonstrate their modernity and to open up other opportunities to transform their pastoral systems. This book provides insights into normally hidden technical and social dynamics that are unexpected outcomes of development interventions.
