Clean, safe drinking water is scarce for over 3 billion people across the world. At least 1 billion literally never have access to clean, safe drinking water, putting them at constant risk of severe thirst-related ill health effects, infectious diseases or toxic contamination. Over 100 countries face either sporadic or chronic crisis-level problems related to clean water scarcity.

As the Innocentive project reports:

Yet, over half of the world’s population is at risk for water shortages, with far-reaching effects. Lack of adequate clean water has serious health implications, including the prevalence of water-borne diseases such as cholera, typhoid, hepatitis A and E, and diarrhea. Globally, diarrhea is the leading cause of illness and death and 88% of those deaths are due to inadequate sanitation and availability of clean water. Water shortages also foment civil unrest and often lead to violence and regional conflicts, as we have seen in Darfur, Somalia, Chad, Nigeria and Sri Lanka, among others. Lack of water perpetuates poverty, increases the risk of political instability, and affects global prosperity.

Overfishing has depleted fish-stocks the world over. Subsidies and lack of enforcement of sustainability measures drive the fishing industry to deplete the very stocks on which its existence depends, while climate interference and global contamination are leaving oceans so hypoxic (oxygen deprived) they cannot support marine life. At least 405 such ‘dead zones’ have been identified across the globe.

According to a NASA report, hypoxia is so extreme in some areas, that total anoxia (zero oxygen availability) can be found, allowing for no animal life to exist. In the Mississippi River delta, feeding into the Gulf of Mexico, it is thought that agricultural waste is creating a glut of nutrients for phytoplankton, which leaves excess organic matter for bottom-dwelling bacteria to feed on.

With the blown-out well spewing between 800,000 and 2 million gallons of oil per day into the Gulf of Mexico, we need new ideas. Join the discussion now to propose any ideas on the technical challenges of the Deepwater Horizon disaster…

Even as Transocean, Halliburton and BP, each seek to lay blame at the feet of the other over what actions or inaction led to the explosion and the catastrophic ongoing spill, it is now amply apparent that there is no known way to seal a well pouring crude oil with such force. BP’s attempt to use dispersants to break up the slick has led to an EPA mandate that they find less toxic chemicals, to avoid threatening the environment and the health and wellbeing of the human population.

Rep. Ed Markey (D-MA) said yesterday: “BP has lost all credibility. Now the decisions will have to be made by others, because it is clear that they have been hiding the actual consequences of this spill.” Reports from numerous sources suggest the real scale of the ongoing spill is far worse than the 5,000 barrels per day reported by BP, which amounts to 200,000 gallons per day pouring into the Gulf. BP had previously testified it could easily contain a spill as large as 300,000 gallons per day.

The field of ecological research and reporting is a part of the basic human urge to engage the world through reason and a quest for understanding. It is not about seizing control of society’s urges and services and limiting the freedom of anyone, but rather about making sure we have the information we need to make the best choices, then advocating for those choices, when inertia and custom stand in the way of better health — for individuals and in the manner in which human individuals respond to their social and natural environments.

Ecology is the study of what surrounds, what encompasses our everyday activities, it is economics that looks to a broader picture that includes all of the resources and services on which the more limited “economy” depends for its very existence. There is a mischaracterization of ecological science as a vague and ideologically motivated quest to control or rein in corporate enterprise or human behavior generally, and that unjust mischaracterization is a distortion promoted by interests that seek to avoid having to acknowledge or live up to any greater responsibility to the social or natural environment — even where those responsibilities are already written into existing law.

In short, ecology is a study of the balance that might or might not exist among natural systems, and so by definition it must take into account human behavior. Efforts to impede the expansion and the dissemination of the facts brought to light through ecological science are attempts to work against the human interest inherent in finding ways to interact sustainably with the natural systems that provide humanity with a climate and a landscape favorable to civilization, and in concert with which civilization has been built.

Proposals & Analysis on Generative Economics, at TheHotSpring.comWater resource depletion leads not only to chronic scarcity of clean, safe drinking water for increasing numbers of people, but means arable land is harder to cultivate and to maintain. Persistent drought and accelerated desertification (the expansion of deserts into the farmed and/or built environment) are results of water resource depletion.

But the most insidious and threatening long term effect is the erosion of the overall human food supply. With climate destabilization accelerating, arable land increasingly hard to come by, and grain harvests collapsing, the global food supply is under serious threat. Long term political stability, and the defensibility of political borders, is linked to a sustainable food supply.

As Lester Brown notes, in his report “Rethinking Food Production for a World of Eight Billion“:

Farmers are faced with shrinking supplies of irrigation water, a diminishing response to additional fertilizer use, rising temperatures from global warming, the loss of cropland to nonfarm uses, rising fuel costs, and a dwindling backlog of yield-raising technologies. At the same time, they also face fast-growing demand for farm products from the annual addition of 79 million people a year, the desire of some 3 billion people to consume more livestock products, and the millions of motorists turning to crop-based fuels to supplement tightening supplies of gasoline and diesel fuel. Farmers and agronomists are now being thoroughly challenged.

TheHotSpring.net :: NOW, with David Brancaccio, travels to the Indian Himalaya, to examine the problem of persistent accelerating ice melt which is speeding the erosion of glaciers that feed the Ganges River, which in turn provides water for hundreds of millions of people and sustains a precarious but massive food economy.

The Intergovernmental Panel on Climate Change (IPCC) finds global warming is causing glaciers to melt on every continent, and glacial melt is accelerating. It is expected land-based ice-melt could lead to a 3-foot rise in sea levels by the end of this century, a tidal surge, however gradual, that could displace 2-3 billion people living in coastal regions around the world.

But the immediate problem examined by NOW in this video is the potential worldwide food crisis resulting from failing river systems, starved of water fed from glacial sources at the top of their watersheds. The president of the Earth Policy Institute says the resulting scarcity and price-distortions could become a global security threat.

The new administration in Washington, DC, has taken notice: climate change is not about a mild 1º increase in temperature on any given day; it is about a sweeping destabilization of global climate patterns, which could undermine the entire layout of civilization across the world. Building the infrastructure necessary for implementing and sustaining a green energy economy is a security priority in this new environment.

Key to understanding the gravity of climate destabilization are the wide array of catastrophic irreversible impacts that could amplify damage. One such area of concern is what are known as methane hydrates. Real Climate explains that:

There is an enormous amount of methane (CH4) on earth frozen into a type of ice called methane hydrate. Hydrates can form with almost any gas and consist of a ‘cage’ of water molecules surrounding the gas. (The term ‘clathrate’ more generally describes solids consisting of gases are trapped within any kind of cage while hydrate is the specific term for when the cage is made of water molecules). There are CO2 hydrates on Mars, while on Earth most of the hydrates are filled with methane. Most of these are in sediments of the ocean, but some are associated with permafrost soils.

Methane hydrates can be destabilized by warming ocean temperatures. When they are destabilized, they release trapped methane into the oceans, and eventually into the atmosphere. Methane has 8 times the greenhouse effect as carbon dioxide, meaning a massive release would significantly accelerate climate change related to global warming.

In the 1990s, the administration of Pres. Bill Clinton devoted $50 million over five years to researching how to extract fuel for energy generation from methane hydrates and carbon dioxide hydrates. But today’s concern is more focused on the potential harm from allowing any of the methane trapped in methane hydrates to escape into the atmosphere, whether from burning or melt-induced release.

Fredrik Moberg, Albaeco :: Earlier this year UNEP, UNDP and the World Bank teamed up with World Resources Institute to publish a report focusing on the concept of resilience “for cushioning the impacts of climate change and delivering continuing benefits to the poor”. Recently, the Volvo Environment Prize was given to the “father of resilience theory”, C.S. Holling. But what is this resilience-thing really all about? We thought it was about time to try to sort this concept out once and for all.

Resilience has become one of the new buzzwords of sustainability. This is not only due to the fact that the father of resilience theory, Canadian ecologist Crawford “Buzz” Holling, recently won the Volvo Environment Prize, it all started much earlier. The concept of resilience was introduced by Holling already back in 1973 as: “a measure of the ability of systems to absorb change… and still persist”. In an ecological context, resilience is generally described as the long-term capacity of an ecosystem to cope with and adapt to change and perturbation, such as storms, fire and pollution. Hence, it is both the capacity of a system to withstand pressures and to rebuild and renew itself if degraded.

– Resilience is the answer to the question: how can things change and persist at the same time, explains Steve Carpenter, Professor of Zoology at the University of Wisconsin-Madison.

Loss of resilience tends to lead to more vulnerable systems, and possible ecosystem shifts to undesired states that provide fewer ecosystem goods (like fish and crops) and services (like flood control and water purification). Clear lakes can suddenly turn into murky, oxygen-depleted pools, grasslands into shrub-deserts, and coral reefs into algae-covered rubble. It is often caused by gradual loss of biodiversity making the ecosystem progressively more susceptible to disturbances like hurricanes or pollution.

Resilience is the capacity of a system to deal with change and continue to develop. It is both about withstanding shocks or disturbances and regaining functions afterwards. In human systems, this is closely linked to the ability to adapt to changing conditions through learning and innovation or even transformation.

International development cooperation
The report, World Resources 2008: Roots of Resilience: Growing the Wealth of the Poor, which we highlighted in SDU 4/08, is a clear sign that resilience thinking is becoming increasingly mainstreamed in the international development community. It is a joint effort produced by the World Resources Institute, UNEP, UNDP and the World Bank, which argues that properly designed ecosystem-based enterprises can create economic, social, and environmental resilience that cushion the impacts of climate change, and deliver continuing benefits to the poor.

– Economic and social progress rests on a healthy environment, from local ecosystems to the biosphere as a whole. Maintaining the resilience of ecosystems is not only a question of saving the environment. It is about securing human development, explains Carl Folke of the Stockholm Resilience Centre.

A perspective – not a measure
In recent times, many resilience scholars have started to put much more emphasis on the social side of the resilience theory and also focused more on the adaptability and renewal of coupled systems of humans and nature – so-called social-ecological systems (SES).

Following this, the resilience concept has developed more into a perspective than a measure, a perspective recently defined to encompass the three aspects: (1) Persistence: the capacity of a system to maintain structure and function when faced with shocks and change (e.g. for a forest to withstand a storm); (2) Adaptability: the collective capacity of people in SES to adapt to changing conditions in order to stay within a desired state (e.g. the ability to safeguard current food production systems under climate change); and (3) Transformability: the capacity of people in SES to learn, innovate and transform in periods of crisis in order to create a new system when ecological, social or economic conditions make the existing system untenable (e.g. turning the current financial crisis into an opportunity to transform the global economy).

As the “perfect storm” gathers from inchoate, deceptively non-threatening winds, we can look ahead, backward and into the mirror and ask how crisis comes, or why, if it is inevitable, if we might just fall right out of it, as we fell into it. But the answer is simple: human crisis comes from excess, from inordinate ambition, from misplaced aggression, from over-exploitation of resources, each of which generates real and problematic tension across the landscape of human experience.

The Dust Bowl of the 1930s resulted from a misguided atomized over-exploitation of arable land. Ancient Sumerian civilization collapsed entirely because excesses of irrigation coupled with poor planning raised soil salinity to levels toxic to agriculture. At the end of the 20th century, global industrial activity had come to far outstrip the available resources feeding into it, and our global economy had come to depend on increasing demand and increasing output to feed unsustainable rates of increasing growth, across the planet.

Something had to give. The mathematics of the whole big picture had come to rest on the assumption that already over-stressed basic resources could expand along with economic expansion. They could not. We may now be seeing just the beginning of this realignment of economic expectations, forced by circumstance.

As major resource scarcity spreads, with China losing ever more arable land to encroaching northwestern deserts and road building in the industrial east, as China’s exploding demand for petroleum, steel, copper, water, meat and grains, put pressure on world markets and pushes the cost of basic goods like food staples ever higher across the world, as the unsustainable demand for fuel moves the US corn belt to shift to cropping for ethanol —as much as 40% of world corn exports are from Iowa, which now devotes 18% of harvest to bio-ethanol—, we are experiencing the natural results of an economy that hinges on hyper-exploitation of resources. The correction, when fully upon us, may yet be far more severe than the 2008 credit-freeze crisis.

Hyper-exploitation is a doctrine: it underpins public policy, government spending, security policy and the philosophical arguments for and against deregulation and the trickle-down theory of economic growth as related to tax policy. It requires that we believe in unstated, unproven modes of natural replenishment; it is a proposition that all things can be tapped, moved, transformed and spent, infinitely, because somehow, the market will set all the right limits and excesses will never be so severe as to ignore the laws of nature.

It is, for this reason, dangerous, because it not only is a doctrine that requires us to use more of the vital resources we require than can be replaced at sustainable levels, it moves us deeper into the vice of living on borrowed time. The result is that we must periodically learn the lesson that borrowed time cannot be financed, that we must pay the full price when it comes due, and our unprecedented resource depletion will leave us, quite simply, without the level of supply required to sustain our standard of living.

Already, wealthy governments are moving to take over cropland in poor countries in order to shore up their own food supplies, as the food security crisis spreads throughout the world, affecting even the wealthiest economies. The fear is that this over-consumption now extending to land use in poor foreign states may lead to a wave of mass starvation throughout the developing world, sparking conflicts and threatening the integrity of the international system as such.

According to the Guardian’s Julian Borger:

“In the context of arable land sales, this is unprecedented,” Atkin said. “We’re used to seeing 100,000-hectare sales. This is more than 10 times as much.”

At a food security summit in Rome, in June, there was agreement to channel more investment and development aid to African farmers to help them respond to higher prices by producing more. But governments and corporations in some cash-rich but land-poor states, mostly in the Middle East, have opted not to wait for world markets to respond and are trying to guarantee their own long-term access to food by buying up land in poorer countries.

India and Bangladesh are constantly disputing river water resources that both countries depend on for basic sustenance for tens of millions of people. Ethiopia, Sudan and Egypt are gripped by a struggle over control of the Nile’s water, with the river running dry at the Nile delta on the Mediterranean during some seasons. The Colorado River in the US has failed to reach the sea and is seeing its flow through the Grand Canyon significantly reduced, as states in the Colorado River Basin dispute claims on the river’s water.

Hyper-exploitation even extends to the use of natural resources like water as dumping grounds. The level of toxic chemicals and plastic polymer byproducts now found in ocean water the world over has reached alarming levels, threatening vast ecosystems and undermining the health of human beings and wildlife in most of the world. Drinking water across the US was found to be contaminated by high levels of pharmaceuticals earlier this year, raising the specter of as yet unknown potential harm to public health, over the long term.

High levels of contaminant emissions or toxic dumping are an abusive use of natural resources we often overlook —like air, land, water and forest cover— in our quest for combustible fuels, industrial-scale production and economies of scale we hope will reduce costs, even if they also increase the risk to our long-term economic and physical health and wellbeing. We are now facing a structural economic crisis, which requires us to reformulate and rebuild our economic model, at the most basic levels, a process which will be more or less painful, depending on how seriously we commit to getting it done and done right.
