Global Geographical Heritage, Geoparks and Geotourism


Book Description

This book explores the geographical, geomorphological, ecological, touristic and socioeconomic aspects of natural heritage, argues for the dynamic conservation of that heritage and explains its key characteristics, promotion, conservation and management to achieve sustainable development goals. Emerging concepts such as geodiversity, geographical heritage sites, geomonuments, geoparks and geotourism are increasingly being used by conservationists. At present, the development of geoparks is a major global theme involving the application of geosciences to promote the inclusive growth of society and the protection and conservation of our unique geoheritage. Currently, there are 147 UNESCO global geoparks across 41 countries, in addition to a number of national-level geoparks. Pursuing a holistic approach towards such sites will sensitise the general public to the need for geoconservation of significant geosites and promote it through geotourism. It is a crucial issue, as various countries around the world are eager to develop their geoparks and are working for the conservation of geoheritage sites at the national level. This unique book gathers contributions from 15 countries in the form of case studies analysing the realities on of geographical heritage, geoparks and geotourism. The respective chapters address the role of geoparks as essential tools for education, recreation and nature conservation. Given its scope, the book offers a valuable guide for geoscientists, planners, policymakers, civil society and anyone concerned about the conservation of geoheritage sites and geoparks for a sustainable future Earth.




Desert Landscapes of the World with Google Earth

This book presents an introduction to desert landscapes—primarily landforms that are natural and man-made. It is based around the presentation of a series of beautiful and informative annotated Google Earth images. These are accompanied by text that describes the feature(s) concerned, their location, and their origin. There are also, in some cases, ground images taken by the author.




Soil Organic Matter and Feeding the Future


Book Description

Soil organic matter (SOM) is the primary determinant of soil functionality. Soil organic carbon (SOC) accounts for 50% of the SOM content, accompanied by nitrogen, phosphorus, and a range of macro and micro elements. As a dynamic component, SOM is a source of numerous ecosystem services critical to human well-being and nature conservancy. Important among these goods and services generated by SOM include moderation of climate as a source or sink of atmospheric CO2 and other greenhouse gases, storage and purification of water, a source of energy and habitat for biota (macro, meso, and micro-organisms), a medium for plant growth, cycling of elements (N, P, S, etc.), and generation of net primary productivity (NPP). The quality and quantity of NPP has direct impacts on the food and nutritional security of the growing and increasingly affluent human population. Soils of agroecosystems are depleted of their SOC reserves in comparison with those of natural ecosystems. The magnitude of depletion depends on land use and the type and severity of degradation. Soils prone to accelerated erosion can be strongly depleted of their SOC reserves, especially those in the surface layer. Therefore, conservation through restorative land use and adoption of recommended management practices to create a positive soil-ecosystem carbon budget can increase carbon stock and soil health. This volume of Advances in Soil Sciences aims to accomplish the following: Present impacts of land use and soil management on SOC dynamics Discuss effects of SOC levels on agronomic productivity and use efficiency of inputs Detail potential of soil management on the rate and cumulative amount of carbon sequestration in relation to land use and soil/crop management Deliberate the cause-effect relationship between SOC content and provisioning of some ecosystem services Relate soil organic carbon stock to soil properties and processes Establish the relationship between soil organic carbon stock with land and climate Identify controls of making soil organic carbon stock as a source or sink of CO2 Connect soil organic carbon and carbon sequestration for climate mitigation and adaptation




Drainage Basin Dynamics


Book Description

This volume provides a versatile introduction to the study of drainage basin evolution, morphology, drainage basin hydrology and sedimentology, human interference, natural and anthropogenic hazards and various management techniques. This book offers the responsible factors of sediment yield and their absolute and specific growth and rate of delivery through tributaries to the main streams. Rivers are important geomorphic agents which reflect an amazing variety of form and behaviour, showing the wide range of natural environment in which they are originated. The drainage system evolution and spatial network development within the dynamic nature are being discussed and how they are adjusted in the geomorphic time scale over the millions of years. This book shows how drainage systems function and react to change and why this thoughtful is required for flourishing integrated basin management. In tropical and sub-tropical countries population pressures as well as different developmental projects are being executed on the drainage basin without proper planning. Today scientists consider drainage basin as an administrative unit during implementation of regional projects. In this context this book will carry a bench mark for scholars and young scientists.







Proceedings of the Global Symposium on Soil Erosion


Book Description

The proceedings book of the Global Symposium on Soil Erosion (GSER19) contains all papers presented both orally and in poster format during the symposium (15-17 May 2019, FAO HQ). The papers presented have provided sufficient scientific evidence to show that soil erosion is a global threat to food production systems, available land for future demand, rural livelihoods, human health and biodiversity, and that coordinated effective action needs to be fostered and accelerated to address this issue. Studies presented provided scientific evidence that soil erosion is accelerated by anthropogenic action. In the current context of population increase and climate change, urgent action is needed from governments to support farmers and land-users in the transition to sustainable production systems, and crucial action is needed at global level to raise awareness of the importance of healthy and productive soils, to ensure a sustainable future and the achievement of many of the SDGs targeting hunger, water quality, and life on land, amongst others.

The Earth′s Land Surface


Book Description

"Given the sheer scale of the topic under consideration here, Professor Gregory does well to condense it into bite-size pieces for the reader. I recommend this text to all undergraduate students of physical geography and earth sciences, particularly to those in their first and second years... This book is a comprehensive and (crucially) inexpensive text that will provide students with a useful source on geomorphology." - Lynda York, The Geographical Journal "I would highly recommend this to anyone doing geology or geography at university as a ′go to′ book for geomorphology and landform." - Sara Falcone, Teaching Earth Science "An excellent source of information for anyone who needs a well-informed, easy to use reference volume to introduce them to the fascinating complexities of the earth’s land surface, past, present and future." - Angela Gurnell, Queen Mary, University of London This introductory text details the land surface of the earth in a readable style covering the major issues, key themes and sensitivities of the environments/landscape. Emphasising the major ideas and their development, each chapter includes case studies and details of influential scientists (not necessarily geomorphologists) who have contributed to the progress of understanding. Providing a very clear explanation of the understanding achieved and of the debates that have arisen, the book is comprised of 12 chapters in four sections: Visualising the land surface explains and explores the composition of the land surface and outlines how it has been studied. Dynamics of the land surface considers the dynamics affecting the earth′s land surface including its influences, processes and the changes that have occurred. Environments of the land surface looks to understand the land surface in major world regions highlighting differences between the areas. Management of the land surface is an examination of the current and future prospects of the management of the earth′s land surface. With pedagogical features including further reading, questions for discussion and a glossary, this original, lively text is authored by one of the leading experts in the field and will be core reading for first and second year undergraduates on all physical geography courses.
