Available in PDF, EPUB and Kindle. Book excerpt: Presenting the latest research on cross-cultural people-plant relationships, this volume conveys the psychological, physiological, and social responses to plants and the significant role these responses play in improved physical and mental health. With chapters written by field experts, it identifies research priorities and methodologies and outlines the steps for developing a research agenda to aid horticulturalists in their work with social scientists to gain a better understanding of people-plant relationships. This resource covers a wide array of topics including home horticulture and Lyme disease, indoor plants and pollution reduction, and plants and therapy.

This book was released on 2024-01-09 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 2 of the book ‘Sand Dunes of the Northern Hemisphere’ is sub-titled Characteristics, Dynamics and Provenance of Sand Dunes in the Northern Hemisphere. It brings together a vast body of information and insight into sand dune and desert systems from North Asia, Central Asia, North Africa and the Middle East. Chapters from the Russian Federation include studies on dune systems within the permafrost zone and there is a case study from temperate zone dune system in coastal Japan. Volume 2: Characteristics, Dynamics and Provenance of Sand Dunes in the Northern Hemisphere of 16 chapters in three Parts, focusses on Saharan Africa, Egypt, and Middle East and gives attention to sand mobility and encroachment with case studies from a number of countries where these matters are of concern. We also include chapters on the remote dunes in the permafrost zone and in the hyper-arid deserts of Iran. Case studies are used to highlight the characteristics of dunes and their interaction with humans in several widely divergent settings. Volume 2 concludes with some musing on the value of study of the past as key to the future and speculates on what the future might hold in the light of a warmer and drier Earth and a rise in sea level that threaten large tracts of low-lying land with marine incursions and destruction from storm surge. PART 4 Sand Mobility and Encroachment The seven chapters in this Part examine the real-world impact of sand encroachment and dune migration on people and their economic activities and the health, welfare and financial implications related to destruction of infrastructure, including human habitations. PART 5 Sand Dune Landscapes Distribution, Formation and Management Seven Case studies from several geographic regions in Africa, the Middle East, north-east Asia are presented here to demonstrate the underlying mechanisms in dune formation and the diverse approaches to their management. Human impacts such as sand mining, tourism development, combine with natural forces like climate variability to challenge the realization of an optimum management strategy. PART 6 Concluding Thoughts: Coping with an Unknown Future from a Little-known Past The two chapters in Part 6 have special roles. We are privileged to publish new research findings that are summarized here in Chapter 38 from extensive and detailed work conducted in the Kyzyl Kum, and Karakum sand seas of Central Asia. There is a strong belief that further study of the little-known past such as revealed in this study could unlock clues as to what a future Earth might look like. This leads on to speculation in Chapter 39 about the implications of what we already know about global change (not only climate change) and the impact of the Anthropocene on the dune systems, both inland and coastal. Sea level rise, marine incursions and an increase in extreme weather events will affect dune systems and sand seas on the Northern Hemisphere (and beyond).

Download or read book Sustainable Agriculture and the Environment in the Humid Tropics written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 721 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rainforests are rapidly being cleared in the humid tropics to keep pace with food demands, economic needs, and population growth. Without proper management, these forests and other natural resources will be seriously depleted within the next 50 years. Sustainable Agriculture and the Environment in the Humid Tropics provides critically needed direction for developing strategies that both mitigate land degradation, deforestation, and biological resource losses and help the economic status of tropical countries through promotion of sustainable agricultural practices. The book includes: A practical discussion of 12 major land use options for boosting food production and enhancing local economies while protecting the natural resource base. Recommendations for developing technologies needed for sustainable agriculture. A strategy for changing policies that discourage conserving and managing natural resources and biodiversity. Detailed reports on agriculture and deforestation in seven tropical countries.

Download or read book Impacts of Anthropogenic Activities on Watersheds in a Changing Climate written by Luís Filipe Sanches Fernandes and published by MDPI. This book was released on 2021-04-14 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The immediate goal of this Special Issue was the characterization of land uses and occupations (LULC) in watersheds and the assessment of impacts caused by anthropogenic activities. The goal was immediate because the ultimate purpose was to help bring disturbed watersheds to a better condition or a utopian sustainable status. The steps followed to attain this objective included publishing studies on the understanding of factors and variables that control hydrology and water quality changes in response to human activities. Following this first step, the Special Issue selected work that described adaption measures capable of improving the watershed condition (water availability and quality), namely LULC conversions (e.g., monocultures into agro-forestry systems). Concerning the LULC measures, however, efficacy was questioned unless supported by public programs that force consumers to participate in concomitant costs, because conversions may be viewed as an environmental service.

Available in PDF, EPUB and Kindle. Book excerpt: "How am I concerned about the environment from where I stand professionally?" Or, "what is the environmental edge of my profession?" A number of outstanding academics were asked to consider these questions in 1989 with the aim of opening an innovative discussion on environmental changes and an understanding of how these are related to human activities. At the personal invitation of the Programme Committee, 17 individuals, each of whom have different professional backgrounds and nationalities, prepared a paper and met for a symposium in Elsinore, Denmark, in September of 1990. Some of the authors revised their original papers as a result of the discussions during the symposium. After peer review and editing, the contributions were printed in this book in versions that express the authors' personal convictions and priority environmental concerns. The authors contributed to the symposium by delivering papers and participat ing in stimulating and sometimes provocative discussions. The Programme Committee is grateful for the professional inspiration provided and for the spiritual and warm, social atmosphere in which the symposium took place.
