Puerto Rican Karst


Book Description

The limestone region of PR covers about 27% of the island1s surface and has karst features. The karst belt (KB), that part of the northern limestone with the most spectacular karst landforms, covering 65% of the northern limestone, is the focus here. Chapters: geography; features: geomorphological, hydrological, and ecological diversity; nat1l. resources; econ. importance: water, other minerals, ag., forestry, and environ. disturbances; history of intensive use; vulnerable to human activity: cutting vs. paved over forests, draining vs. filling wetlands, conversion vs. trans1n. of land uses, pumping vs. overdrafting aquifers, contaminating vs. poisoning ground water, and surface water pollution; and proposal for transferring KB to the public domain.

Global Climate Change Impacts in the United States


Book Description

Summarizes the science of climate change and impacts on the United States, for the public and policymakers.




Stratospheric Ozone Depletion and Climate Change


Book Description

In recent years, several new concepts have emerged in the field of stratospheric ozone depletion, creating a need for a concise in-depth publication covering the ozone-climate issue. This monograph fills that void in the literature and gives detailed treatment of recent advances in the field of stratospheric ozone depletion. It puts particular emphasis on the coupling between changes in the ozone layer and atmospheric change caused by a changing climate. The book, written by leading experts in the field, brings the reader the most recent research in this area and fills the gap between advanced textbooks and assessments.




Legumes for Soil Health and Sustainable Management


Book Description

Sustainable management of soils is an important global issue of the 21st century. Feeding roughly 8 billion people with an environmentally sustainable production system is a major challenge, especially considering the fact that 10% of the world’s population at risk of hunger and 25% at risk of malnutrition. Accordingly, the 68th United Nations (UN) general assembly declared 2016 the “International Year of Pulses” to raise awareness and to celebrate the role of pulses in human nutrition and welfare. Likewise, the assembly declared the year 2015 as the “International Year of Soils” to promote awareness of the role of “healthy soils for a healthy life” and the International Union of Soil Science (IUSS) has declared 2015-2024 as the International Decade of Soils. Including legumes in cropping systems is an important toward advancing soil sustainability, food and nutritional security without compromising soil quality or its production potential. Several textbooks and edited volumes are currently available on general soil fertility or on legumes but‚ to date‚ none have been dedicated to the study of “Legumes for Soil Health and Sustainable Management”. This is important aspect, as the soil, the epidermis of the Earth (geoderma)‚ is the major component of the terrestrial biosphere. This book explores the impacts of legumes on soil health and sustainability, structure and functioning of agro-ecosystems, agronomic productivity and food security, BNF, microbial transformation of soil N and P, plant-growth-promoting rhizobacteria, biofertilizers, etc. With the advent of fertilizers, legumes have been sidelined since World War II, which has produced serious consequences for soils and the environment alike. Therefore, legume-based rational cropping/soil management practices must support environmentally and economically sustainable agroecosystems based on (sequential) rotation and intercropping considerations to restore soil health and sustainability. All chapters are amply illustrated with appropriately placed data, tables, figures, and photographs, and supported with extensive and cutting-edge references. The editors have provided a roadmap for the sustainable development of legumes for food and nutritional security and soil sustainability in agricultural systems, offering a unique resource for teachers, researchers, and policymakers, as well as undergraduate and graduate students of soil science, agronomy, ecology, and the environmental sciences.







Sustainable Bioeconomy


Book Description

Sustainable development is the most important challenge facing humanity in the 21st century. The global economic growth in the recent past has indeed exhibited marked progress in many countries. Nevertheless, the issues of income disparity, poverty, gender gaps, and malnutrition are not uncommon in the global landscape, in spite of the upward growth of the economy and technological advances. This grim picture is further exacerbated by our growing human population, unmindful resource use, ever-increasing consumption trends, and changing climate. In order to protect humanity and preserve the planet, the United Nations issued the “2030 agenda for sustainable development,” which includes but is not limited to sustainable production and consumption practices, e.g. in a sustainable bioeconomy. The hallmark of the sustainable bioeconomy is a paradigm shift from a fossil-fuel-based economy to a biological-based one, which is driven by the virtues of sustainability, efficient utilization of resources, and “circular economy.” As the sustainable bioeconomy is based on the efficient utilization of biological resources and societal transformations, it holds the immense potential to achieve the UN’s Sustainable Development Goals. This book shares valuable insights into the linkages between the sustainable bioeconomy and Sustainable Development Goals, making it an essential read for policymakers, researchers and students of environmental studies.




Kenya's Indigenous Forests


Book Description

The result of work of the Kenya Indigenous Forest Conservation Programme, this report provides a summary of the existing information about Kenya's indigenous forests. It covers geographical background; assessment of the biodiversity, environmental services, and wood products functions and values; population pressures; utilization; economic value; policy; legislation; management guidelines; and criteria for management planning of such forests.




Water Supply Planning


Book Description

As a source of reference material for the practising water engineer or water manager, this book outlines a strategy for projecting water consumption for specific types of land use and selecting a water conservation programme to maximise the beneficial use of a limited natural resource - a situation that typifies new development nationally and worldwide.
