Freshwater ecosystems and their resident species have declined more rapidly than either terrestrial or marine systems and their species. Freshwater ecosystems face myriad stressors, from habitat loss and pollution to dams and climate change. Today I discuss the state of freshwater conservation science with Ian Harrison. Ian obtained his Ph.D. in systematic ichthyology at the University of Bristol in the UK. He has conducted research on marine and freshwater fishes in Europe, Central and South America, Africa, the Philippines, and the Central Pacific. He has worked for Conservation International and the IUCN’s Global Species Programme since 2008 and he is currently the freshwater specialist for Conservation International’s Moore Center for Science. Ian publishes extensively on the biology and conservation of fishes and the conservation of freshwater ecosystems.
Pollution, altered flows and climate change are now placing what once seemed like endless supplies of fresh water at risk, leading to growing recognition of the importance of Indigenous water science.
Hydraulic fracking is the process of extracting natural gas from rocks in the earth by breaking them apart. chemicals are pumped into a targeted area and after the rocks are broken, gas is released up through a pipe and shipped off in a truck to whatever plant wants it. One of the many problems with fracking is that methane gas escapes during the mining process, polluted flow back water may get injected into a deep storage well recycled or sent to a treatment plant. fracking fluid is forced to underground at high pressure and toxic chemicals seep into the bedrock. The toxins in the bedrock seep into the drinking water aquifers and contaminate the water from the aquifers that enter the drinking water systems.
Sewage is now discharged into our rivers and seas on a regular basis. It's joined by agricultural pollution and a host of microplastics. In this special debate programme, Tom Heap asks what's gone wrong with our water system. How did we get into this situation, what will it cost to put it right, and how can we go about sorting out the mess we seem to be in? Tom is joined by a panel of experts to discuss the history, the finances and the future of cleaning up our waterways.
Water covers over 70% of the world’s surface, but only 0.5% of the earth’s water is available as fresh water. Water pollutants are causing irreversible damage to ecosystems and global warming is adding to the burden. Are we too late to clean up this mess?
Returning to the podcast to discuss water desalination is Mark Holtzapple. Mark is a Professor of Chemical Engineering at Texas A&M University where he researches technologies that improve sustainability. With close to 30 years of experience as a researcher, Mark is constantly finding new ways to turn waste into useful products. So what’s his take on obtaining fresh water from saltwater?
In this episode, you will learn about:
Imagine a world where freshwater is as plentiful as seawater… With the work that researchers like Mark Holtzapple are doing, this idea may be more realistic than you may think!

Drinking Water by
When we turn on the tap or twist open a tall plastic bottle, we probably don't give a second thought about where our drinking water comes from. But how it gets from the ground to the glass is far more convoluted than we might think.In this revised edition of Drinking Water, Duke University professor and environmental policy expert James Salzman shows how drinking water highlights the most pressing issues of our time. He adds eye-opening, contemporary examples about our relationship to and consumption of water, and a new chapter about the atrocities that occurred in Flint, Michigan. Provocative, insightful, and engaging, Drinking Water shows just how complex a simple glass of water can be.
Drying Up by
America's wettest state is running out of water. Yes, Florida-with its swamps, lakes, extensive coastlines, and legends of life-giving springs-faces a drinking water crisis that most people don't see coming. Drying Up is a wake-up call and a hard look at what the future holds for those who call Florida home. Journalist and educator John Dunn untangles the many causes of the state's freshwater problems. Drainage projects, construction, and urbanization, especially in the fragile wetlands of South Florida, have changed and shrunk natural water systems. Failing water infrastructure and increasing outbreaks of toxic algae are worsening pollution problems. Climate change, sea level rise, and groundwater pumping are spoiling freshwater resources with saltwater intrusion. Because of water shortages, fights have broken out over rights to the Apalachicola River, Lake Okeechobee, the Everglades, and other important watersheds. Many scientists think Florida has already passed the tipping point, Dunn warns. Drawing on hundreds of interviews and years of research, he affirms that soon there will not be enough water to meet demand if "business as usual" prevails. He investigates previous and current restoration efforts as well as proposed future solutions, including the "soft path for water" approach that uses green infrastructure to mimic natural hydrology. As millions of new residents are expected to arrive in Florida in the coming decades, this book is a timely introduction to a problem that will escalate dramatically-and not just in Florida. Dunn cautions that freshwater scarcity is a worldwide trend that can only be tackled effectively with the cooperation and single-minded focus of all whose lives depend on the most precious substance on earth.
Fracking by
On the surface, fracking, or hydraulic fracturing, seems like a perfect solution to the country's energy crises. It is a relatively easy and independent way to supply natural gas. But controversies surround the practice. The process involved in fracking has been shown to be harmful to the environment and a threat to our public health. Do the benefits of fracking outweigh the costs? Can improvements be made to the process that would eliminate its dangers? Should the government get more involved in regulating fracking, or should it be up to the people?
Fractured Communities by
While environmental disputes and conflicts over fossil fuel extraction have grown in recent years, few issues have been as contentious in the twenty-first century as those surrounding the impacts of unconventional natural gas and oil development using hydraulic drilling and fracturing techniques--more commonly known as "fracking"--on local communities. In Fractured Communities, Anthony E. Ladd and other leading environmental sociologists present a set of crucial case studies analyzing the differential risk perceptions, socio-environmental impacts, and mobilization of citizen protest (or quiescence) surrounding unconventional energy development and hydraulic fracking in a number of key U.S. shale regions. Fractured Communities reveals how this contested terrain is expanding, pushing the issue of fracking into the mainstream of the American political arena.
High and Dry by
An engaging call to understand and protect groundwater, the primary source of drinking water for almost half of the world's population Groundwater is essential for drinking water and food security. It provides enormous environmental benefits by keeping streams and rivers flowing. But a growing global population, widespread use of industrial chemicals, and climate change threaten this vital resource. Groundwater depletion and contamination has spread from isolated areas to many countries throughout the world. In this accessible and timely book, hydrology expert William M. Alley and science writer Rosemarie Alley sound the call to protect groundwater. Drawing on examples from around the world, including case studies in the United States, Canada, Australia, India, and Sub-Saharan Africa, the authors examine groundwater from key scientific and socioeconomic perspectives. While addressing the serious nature of groundwater problems, the book includes stories of people who are making a difference in protecting this critical resource.
Planetary Health by
Human health depends on the health of the planet. Earth's natural systems--the air, the water, the biodiversity, the climate--are our life support systems. Yet climate change, biodiversity loss, scarcity of land and freshwater, pollution and other threats are degrading these systems. The emerging field of planetary health aims to understand how these changes threaten our health and how to protect ourselves and the rest of the biosphere. Planetary Health: Protecting Nature to Protect Ourselves provides a readable introduction to this new paradigm. With an interdisciplinary approach, the book addresses a wide range of health impacts felt in the Anthropocene, including food and nutrition, infectious disease, non-communicable disease, dislocation and conflict, and mental health. It also presents strategies to combat environmental changes and its ill-effects, such as controlling toxic exposures, investing in clean energy, improving urban design, and more. Chapters are authored by widely recognized experts. The result is a comprehensive and optimistic overview of a growing field that is being adopted by researchers and universities around the world. Students of public health will gain a solid grounding in the new challenges their profession must confront, while those in the environmental sciences, agriculture, the design professions, and other fields will become familiar with the human consequences of planetary changes. Understanding how our changing environment affects our health is increasingly critical to a variety of disciplines and professions. Planetary Health is the definitive guide to this vital field.
The Politics of Water Scarcity by
Clean water is something we take for granted. It's there when we turn on our taps to fill a glass, take a shower, or wash our hands. But for many of the world's citizens, water is a precious commodity. Many don't have access to clean water. Others must use the same water for drinking, cooking, and cleaning. Is access to clean water a human right? Should water be provided by governments or private entities? Will water become a commodity of the rich? And how are our environmental practices affecting the world's supply of water?
The Source by
America has more than 250,000 rivers, coursing over more than 3 million miles, connecting the disparate regions of the United States. On a map they can look like the veins, arteries, and capillaries of a continent-wide circulatory system, and in a way they are. Over the course of this nation's history rivers have served as integral trade routes, borders, passageways, sewers, and sinks. Over the years, based on our shifting needs and values, we have harnessed their power with waterwheels and dams, straightened them for ships, drained them with irrigation canals, set them on fire, and even attempted to restore them. In this fresh and powerful work of environmental history, Martin Doyle tells the epic story of America and its rivers, from the U.S. Constitution's roots in interstate river navigation, the origins of the Army Corps of Engineers, the discovery of gold in 1848, and the construction of the Hoover Dam and the TVA during the New Deal, to the failure of the levees in Hurricane Katrina and the water wars in the west. Along the way, he explores how rivers have often been the source of arguments at the heart of the American experiment--over federalism, sovereignty and property rights, taxation, regulation, conservation, and development. Through his encounters with experts all over the country--a Mississippi River tugboat captain, an Erie Canal lock operator, a dendrochronologist who can predict the future based on the story trees tell about the past, a western rancher fighting for water rights--Doyle reveals the central role rivers have played in American history--and how vital they are to its future.

Water Politics by
As the world faces another water crisis, it is easy to understand why this precious and highly-disputed resource could determine the fate of entire nations. In reality, however, water conflicts rarely result in violence and more often lead to collaborative governance, however precarious. In this comprehensive and accessible text, David Feldman introduces readers to the key issues, debates, and challenges in water politics today. Its ten chapters explore the processes that determine how this unique resource captures our attention, the sources of power that determine how we allocate, use, and protect it, and the purposes that direct decisions over its cost, availability, and access. Drawing on contemporary water controversies from every continent - from Flint, Michigan to Mumbai, Sao Paulo, and Beijing -the book argues that cooperation and more equitable water management are imperative if the global community is to adequately address water challenges and their associated risks, particularly in the developing world. While alternatives for enhancing water supply, including waste-water re-use, desalination, and conservation abound, without inclusive means of addressing citizens' concerns, their adoption faces severe hurdles that can impede cooperation and generate additional conflicts.
Where the Water Goes by
The Colorado River is a crucial resource for a surprisingly large part of the United States, and every gallon that flows down it is owned or claimed by someone. David Owen traces all that water from the Colorado's headwaters to its parched terminus, once a verdant wetland but now a million-acre desert. He takes readers on an adventure downriver, along a labyrinth of waterways, reservoirs, power plants, farms, fracking sites, ghost towns, and RV parks, to the spot near the U.S.-Mexico border where the river runs dry. Water problems in the western United States can seem tantalizingly easy to solve- just turn off the fountains at the Bellagio, stop selling hay to China, ban golf, cut down the almond trees, and kill all the lawyers. But a closer look reveals a vast man-made ecosystem that is far more complex and more interesting than the headlines let on. The story Owen tells in Where the Water Goes is crucial to our future- how a patchwork of engineering marvels, byzantine legal agreements, aging infrastructure, and neighborly cooperation enables life to flourish in the desert, and the disastrous consequences we face when any part of this tenuous system fails. Praise for David Owen's Green Metropolis-
