Tufton Wants Laws On Water Harvesting

EFFORTS TO preserve the country’s water reserves must be supplemented by legislation that makes rainwater harvesting compulsory for all housing developments and other such major projects which put a drain on Jamaica’s limited water resources during construction.

Dr Christopher Tufton

That is the recommendation from Dr Christopher Tufton, who told The Gleaner that such legislation is overdue, given Government’s failure to examine and report back on a resolution passed in the Senate March 1, 2013 on legislating rainwater harvesting.

“This is yet another example of a country that gives lip service to sustainable development, while citizens have to experience the hardships from a water crisis each year. We have heard nothing of the resolution since then, and as is customary, we act surprised that we are in another water shortage crisis, even though we have this situation each year,” said the former government minister.

He wants to make it mandatory that developers include in their applications information on how they will harvest and store rainwater for use during the life of the project. The legislation also speaks to the incorporation of features such as guttering on individual buildings, to ensure that water conservation becomes a part the Jamaican culture going forward.

“What it would mean is that one could determine to what extent existing projects could be retrofitted or adjusted. For new projects, however, part of their design should include a rainwater harvesting process. Now, it does add to the cost of construction, but in some countries, they have done things like tax rebates, among other things, to incentivise developers,” Tufton said. “So once construction is done, you could get a tax write-off in a short period of time to keep costs to a minimum.”

Acknowledging that this additional cost might prove a deterrent for some investors, Tufton said one has to look at the much bigger picture of the emotional distress and financial fallout the country is now experiencing. More

A Thirsty, Violent World

They say you learn something new everyday. For me, this day qualifies. Michael Specter writes at the New Yorker on the increasingly dire prospects for water -- of the clean, unpolluted kind -- for a clamoring humankind and of the water wars that are surely on the horizon.

And he has this, on the origins of the word "rivals": "After all, the word 'rivals' has its roots in battles over water—coming from the Latin, rivalis, for 'one taking from the same stream as another.'” Who knew? Not me. Specter's prognostication on our looming water disasters is a grim but important read and not just for Pakistanis or Nigerians, but for us in a country in which California is parched for water in a prolonged drought and researchers are predicting humongous droughts coming later in the century for our breadbasket, the Midwest! TomDispatch



A Thirsty, Violent World

Angry protesters filled the streets of Karachi last week, clogging traffic lanes and public squares until police and paratroopers were forced to intervene. That’s not rare in Pakistan, which is often a site of political and religious violence.

But last week’s protests had nothing to do with freedom of expression, drone wars, or Americans. They were about access to water. When Khawaja Muhammad Asif, the Minister of Defense, Power, and Water (yes, that is one ministry), warned that the country’s chronic water shortages could soon become uncontrollable, he was looking on the bright side. The meagre allotment of water available to each Pakistani is a third of what it was in 1950. As the country’s population rises, that amount is falling fast.

Dozens of other countries face similar situations—not someday, or soon, but now. Rapid climate change, population growth, and a growing demand for meat (and, thus, for the water required to grow feed for livestock) have propelled them into a state of emergency. Millions of words have been written, and scores of urgent meetings have been held, since I last wrote about this issue for the magazine, nearly a decade ago; in that time, things have only grown worse.

The various physical calamities that confront the world are hard to separate, but growing hunger and the struggle to find clean water for billions of people are clearly connected. Each problem fuels others, particularly in the developing world—where the harshest impact of natural catastrophes has always been felt. Yet the water crisis challenges even the richest among us.

California is now in its fourth year of drought, staggering through its worst dry spell in twelve hundred years; farmers have sold their herds, and some have abandoned crops. Cities have begun rationing water. According to the London-based organization Wateraid, water shortages are responsible for more deaths in Nigeria than Boko Haram; there are places in India where hospitals have trouble finding the water required to sterilize surgical tools.

Nowhere, however, is the situation more acute than in Brazil, particularly for the twenty million residents of São Paulo. “You have all the elements for a perfect storm, except that we don’t have water,” a former environmental minister told Lizzie O’Leary, in a recent interview for the syndicated radio show “Marketplace.” The country is bracing for riots. “There is a real risk of social convulsion,” José Galizia Tundisi, a hydrologist with the Brazilian Academy of Sciences, warned in a press conference last week. He said that officials have failed to act with appropriate urgency. “Authorities need to act immediately to avoid the worst.” But people rarely act until the crisis is directly affecting them, and at that point it will be too late.

It is not that we are actually running out of water, because water never technically disappears. When it leaves one place, it goes somewhere else, and the amount of freshwater on earth has not changed significantly for millions of years. But the number of people on the planet has grown exponentially; in just the past century, the population has tripled, and water use has grown sixfold. More than that, we have polluted much of what remains readily available—and climate change has made it significantly more difficult to plan for floods and droughts.

Success is part of the problem, just as it is with the pollution caused by our industrial growth. The standard of living has improved for hundreds of millions of people, and the pace of improvement will quicken. As populations grow more prosperous, vegetarian life styles often yield to a Western diet, with all the disasters that implies. The new middle classes, particularly in India and China, eat more protein than they once did, and that, again, requires more water use. (On average, hundreds of gallons of water are required to produce a single hamburger.)

Feeding a planet with nine billion residents will require at least fifty per cent more water in 2050 than we use today. It is hard to see where that water will come from. Half of the planet already lives in urban areas, and that number will increase along with the pressure to supply clean water.

“Unfortunately, the world has not really woken up to the reality of what we are going to face, in terms of the crises, as far as water is concerned,” Rajendra Pachauri, the chairman of the International Panel on Climate Change, said at a conference on water security earlier this month. “If you look at agricultural products, if you look at animal protein, the demand for which is growing—that’s highly water intensive. At the same time, on the supply side, there are going to be several constraints. Firstly because there are going to be profound changes in the water cycle due to climate change.”

Floods will become more common, and so will droughts, according to most assessments of the warming earth. “The twenty-first-century projections make the [previous] mega-droughts seem like quaint walks through the garden of Eden,” Jason Smerdon, a climate scientist at Columbia University’s Lamont-Doherty Earth Observatory, said recently. At the same time, demands for economic growth in India and other developing nations will necessarily increase pollution of rivers and lakes. That will force people to dig deeper than ever before into the earth for water.

There are ways to replace oil, gas, and coal, though we won’t do that unless economic necessity demands it. But there isn’t a tidy and synthetic invention to replace water. Conservation would help immensely, as would a more rational use of agricultural land—irrigation today consumes seventy per cent of all freshwater.

The result of continued inaction is clear. Development experts, who rarely agree on much, all agree that water wars are on the horizon. That would be nothing new for humanity. After all, the word “rivals” has its roots in battles over water—coming from the Latin, rivalis, for “one taking from the same stream as another.” It would be nice to think that, with our complete knowledge of the physical world, we have moved beyond the limitations our ancestors faced two thousand years ago. But the truth is otherwise; rivals we remain, and the evidence suggests that, until we start dying of thirst, we will stay that way. More

Drought Management Experts Examine Tools to Address Water Scarcity

21 November 2014: The UN Educational, Scientific and Cultural Organization (UNESCO), the Centre for Natural Resources and Development (CRND), the Climate Services Partnership, the International Centre for Integrated Water Resources Management (ICIWaRM) and the government of Flanders, Belgium, organized an international symposium on ‘Building a Community of Practice on Drought Management Tools'.


The meeting aimed to: develop project proposals and solutions to promote international cooperation on drought; and establish a community of practice to share information and develop drought management tools. The community of practice will be integrated into existing regional networks, including: Aridas-Latin America and the Caribbean (LAC); CNRD; the UNESCO Global Network for Water and Development Information in Arid Lands (G-WADI); and Columbia University Global Centres.


The meeting took place from 19-21 November 2014, in Santiago, Chile. [UNESCO Press Release] [Symposium Website] More

We throw out more food than plastic, paper, metal, and glass

The much-anticipated U.N. Climate Summit, which began a few days ago in New York, and was ostensibly a platform for world leaders to leap frog debates over whether climate change is real, and skip straight to discussions centered around how to overcome the challenges it poses.

But it’s also an impetus for those beyond the sessions’ panels to illuminate troubling patterns of behavior that are contributing to our collective carbon footprint—and food waste is without question one of the most egregious, especially in the United States.

In 2012, the most recent year for which estimates are available, Americans threw out roughly 35 million tons of food, according to the Environmental Protection Agency. That’s almost 20 percent more food than the United States tossed out in 2000, 50 percent more than in 1990, and nearly three times what Americans discarded in 1960, when the country threw out a now seemingly paltry 12.2 million tons.

“Food waste is an incredible and absurd issue for the world today,” Jose Lopez, Nestle’s head of operations said of the issue earlier this month.

Take as percentages, not tonnage.

Roughly a third of the food produced worldwide never gets eaten. The problem is particularly egregious in developed countries, where food is seen as being more expendable than it is elsewhere. “Every year, consumers in rich countries waste almost as much food (222 million tonnes) as the entire net food production of sub-Saharan Africa (230 million tonnes),” the U.N. notes on its website.

This country is one of the worst offenders: a 2012 paper by the Natural Resources Defense Council estimated that as much as 40 percent of America’s food supply ends up in a dumpster.

The most obvious problem with this waste is that while Americans are throwing out their food, an estimated one in every nine people in the world still suffers from chronic hunger—that is, insufficient food—including more than 200 million in Sub-Saharan Africa and more than 500 million Asia. Even in the United States, where that number is significantly lower, some 14 percent of U.S. households still struggled to put food on the table for a portion of last year, according to the USDA.

The level of food waste suggests that curbing hunger isn’t a matter of producing more food so much as better preserving and distributing the food currently being produced. As the United Nations noted in its report on world hunger last week, there is actually enough food to feed all seven billion people living in the world today.

But there’s another less apparent problem with food waste: the threat to the environment. Landfills full of decomposing food release methane, which is said to be at least 20 times more lethal a greenhouse gas than carbon dioxide. And America’s landfills are full of food—organic waste is the second largest contributor to the country’s landfills. Those same landfills are the single largest producer of methane emissions in the United States—they produce almost a quarter of the country’s total methane emissions, according to the NRDC.

The environmental cost of food waste goes further than just methane emissions. Producing food is a costly affair for the environment—an estimated one third of global carbon emissions come from agriculture—but it’s one society pays to feed itself.

The price for producing food that never ends up in someone’s mouth is much more—it includes both the resources and environmental decay sacrificed for its making. The livestock industry contributes more than 15 percent of global carbon emissions, according to the U.N, which means that when Americans throw out meat, they are wasting some of the most environmentally costly food available. More

Given all the discussions concerning the creation of a new landfill here in the Cayman Islands, here a link to creating healthy soil using composted food scraps and hervested water, and helping to reduce waste going to the dump.

UN Climate Summit 2014

Climate change is not a far-off problem. It is happening now and is having very real consequences on people’s lives. Climate change is disrupting national economies, costing us dearly today and even more tomorrow. But there is a growing recognition that affordable, scalable solutions are available now that will enable us all to leapfrog to cleaner, more resilient economies.UN Climate Summit 2014

There is a sense that change is in the air. UN Secretary-General Ban Ki-moon has invited world leaders, from government, finance, business, and civil society to Climate Summit 2014 this 23 September to galvanize and catalyze climate action. He has asked these leaders to bring bold announcements and actions to the Summit that will reduce emissions, strengthen climate resilience, and mobilize political will for a meaningful legal agreement in 2015. Climate Summit 2014 provides a unique opportunity for leaders to champion an ambitious vision, anchored in action that will enable a meaningful, global agreement in Paris in 2015. More

Global Environment Facility’s Caribbean Regional Fund for Wastewater Management

A slate of recently developed Caribbean Integrated Water Resources Management (IWRM) knowledge products, which focus on tools geared toward building climate resilience in the Caribbean water sector, as well as, resources for the wastewater sector professionals, were launched at a two-day (April 29-30) Regional Meeting of Partners in the Water and Wastewater Sector in the Caribbean this week.

The products include those developed under the Caribbean Climate Online Risk and Adaptation Tool (CCORAL)-Water initiative, a joint collaboration between GWP-C and the Caribbean Community Climate Change Centre (CCCCC), funded by the Climate and Development Knowledge Network. The Session will also showcase wastewater videos and materials from the GEF CReW, an effluent discharge database and other resources.

The Global Water Partnership (GWP) technical focus paper on IWRM in the Caribbean: The challenges facing SIDS.

Over the course of the two-day Regional Meeting of Partners in the Water and Wastewater Sector in the Caribbean, the Global Water Partnership-Caribbean (GWP-C), the United Nations Environment Programme, Caribbean Regional Coordinating Unit (UNEP-CAR/RCU) and the Global Environment Facility’s Caribbean Regional Fund for Wastewater Management (GEF CReW) hosted a Knowledge Sharing Session on New Tools and Resources for IWRM in the Caribbean.

IWRM is an holistic approach to managing water that takes into consideration that different uses of water are interdependent. IWRM means that water allocations and management decisions consider the effects of each use on the other. The approach is grounded in the understanding that water resources are an integral component of the ecosystem, a natural resource, and a social and economic good.

Representatives from more than fifty (50) regional and national agencies in water and wastewater management are scheduled to attend the Session. Download Press Release here. More

Developing countries still waiting for a global response to Climate Change: ACP

BRUSSELS, Belgium ---- As president of the Council of Ministers of the African, Caribbean and Pacific states, Samoa's Prime Minister Tuilaepa Sailele Malielegaoi had the perfect forum to voice his concerns about the effects climate change has had on his island nation.

Tuilaepa Sailele Malielegaoi

Tuilaepa, who chaired a two-day ministerial conference in Brussels, earlier his month said that climate change was responsible for the frequency of natural disasters that have befallen Samoa in recent years.

“This is the view shared by most, although sadly we are still waiting for a concerted global response that would at least halt climate change,” he told delegates. Samoa will host the United Nations Conference on Small Island Developing States (SIDS) in 2014.

He said that the extreme danger climate change, ocean acidification and environmental degradation posed to the world could be overstated, adding that “the consequences of this to our island states and all our ACP membership would be devastating” as some observers think “the very existence of low-lying island countries could be in jeopardy.”

Tuilaepa said that assistance from partners such as the European Union (EU) was urgently needed by all ACP countries to support efforts to develop climate resilience through mitigation and adaptation measures "if the sustainability of our development efforts and long-term prospects are to have any meaning."

Jamaica’s ambassador to the ACP, Vilma Kathleen McNish, told IPS that the Caribbean has had to deal with the impact of climate change and it was “obviously a huge challenge.”

“For some of us … it is existential. We rely so much on our coastline in terms of tourism, which is one of our major economic livelihoods,” she said.

She said that the impact of climate change was evident in the Caribbean with sea levels rising and the resultant depletion of fish stocks. There were also increased occurrences of hurricanes. She said that this disrupted the economy of the Caribbean and the livelihoods of its people.

“So for us, climate change at the individual and regional level is a major challenge.”

She said that the SIDS summit in Samoa would be critical for the Caribbean and other developing countries because it would look not only at climate change but at various issues that affect small island developing states leading up to the post 2015 development agenda.

“Most countries in the region [Caribbean] are now putting in place policies geared towards adaptation and mitigation. We still believe, however, that the international community has a responsibility to support our countries in our development,” McNish said.

South Africa’s ambassador Mxolisi Nkosi told IPS that the ACP’s engagement with the EU on this and other matters should be based on the principle of equality, non-conditionality, non-interference and mutual benefit.

“We should call on the international community to commit to limiting a global temperature rise to below two degrees Celsius in a legal instrument, and agree to a common global goal on adaptation as a way to recognise that, despite its local and context specific needs, adaptation is a global responsibility,” Nkosi said.

Tuilaepa said that Samoa, like other SIDS, remained highly vulnerable to the impacts of climate change and environmental degradation.

In the 1990s the Pacific Island nation suffered two devastating cyclones that wiped off industries and businesses that contributed 50 percent of GDP. Tuilaepa said this devastation reversed “economic progress by more than a decade”.

In September 2009, the island was struck by a deadly tsunami that killed more than 140 people and left thousands homeless. In December 2012, another cyclone struck, killing people and wreaking havoc on the infrastructure and the economy.

“For a small island country with a small population, the losses and setbacks from these natural disasters are hardly bearable,” Tuilaepa told IPS.

He said while he was grateful to the EU and other developmental partners for coming to the aid of the island, “Samoa’s experience is repeated in all our Pacific Island countries and, I am sure, right across the ACP membership.”

Last month, ACP countries agreed on a common position paper on the U.N. Framework Convention on Climate Change held in Warsaw, Poland.

The 79-member grouping said adaptation to climate change and mobilising funding from a variety of sources were immediate and urgent priorities for ACP member states that should be addressed in a comprehensive manner at the global level with the same level of priority as mitigation. More

Caribbean water sector managers to benefit from CCORAL

September 16th 2013 A new initiative by the Caribbean Climate Change Centre (5Cs), the UK-based Climate Development and Knowledge Network (CDKN) and the Global Water Partnership – Caribbean is focusing minds on climate risk in the water sector.

In July, the 5Cs launched an innovative online tool to help governments and businesses to assess the climate-related risks of different investment options. The Caribbean Climate Online Risk and Adaptation tool (CCORAL) is a decision support tool that aims to encourage climate resilient choices. In this region of small island states that are vulnerable to sea level rise, droughts and increasingly frequent, intense storms, the tool couldn’t have come at a better time.

CCORAL is intended to embed a risk management ethic in decision-making processes across the Caribbean region. When it was launched, it received a rare endorsement by the Chairman of the Intergovernmental Panel on Climate Change (IPCC) Dr. Rajendra Kumar Pachauri. Now, a new project will fine-tune CCORAL’s online support system for the specific use of managers in the water sector

Most Caribbean countries are vulnerable to water scarcity and drought. One of the contributing factors to vulnerability is climate change, which will trigger significant changes in temperature and precipitation. Average rainfall is expected to decrease by 7% in 2050, and salt water intrusion will arise as a result of increased sea levels. This water scarcity will impact agriculture, tourism and public health.

The Centre, together with the Global Water Partnership Caribbean are working with government agencies and businesses in the water sector to understand how the CCORAL tool could help them. They are currently consulting with a range of regional organisations (such as international financial institutions, NGOs and universities), national agencies (government departments, water utilities) and businesses (water utilities, consultants, major industrial and commercial water users). They are exploring the following key questions:

What are the priority water services which would benefit from more climate resilient decision making? (for example; water resources allocation, water supply, agricultural / industrial / commercial / tourism / energy)

What water information, planning, operational or legal and regulatory activities would benefit from increased consideration of climate variability and risk? (for example; water supply planning, hydrological modelling, risk assessment, water system regulation, operational procedures)

Which organisations and specific capacities would benefit from being involved in the development and application of the CCORAL-Water tools? (for example; strategic water planners in governmental departments, consultants engaged in technical services for water planners, investment planners in water utilities, regulatory agencies for water)

If this project is successful, it will lead to improved climate risk management in water sector planning and management activities, which in turn will lead to improved levels of service for water users in the Caribbean.

The CCORAL-Water project is being developed in consultation with water managers in five countries: Barbados, Belize, Jamaica, Saint Lucia and Suriname. The CCORAL-Water tool itself will be applicable and available to all Caribbean countries through the CCORAL online system, hosted by the 5Cs, from March 2014. Watch this space for progress with CCORAL – Water! More

Atmospheric Warming Altering Ocean Salinity And The Water Cycle

A clear change in salinity has been detected in the world’s oceans, signaling shifts and acceleration in the global rainfall and evaporation cycle tied directly to climate change.

In a paper published … in the journal Science, Australian scientists from the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and Lawrence Livermore National Laboratory reported changing patterns of salinity in the global ocean during the past 50 years, marking a clear symptom of climate change.

Lead author Paul Durack said that by looking at observed ocean salinity changes and the relationship between salinity, rainfall and evaporation in climate models, they determined the water cycle has become 4 percent stronger from 1950-2000. This is twice the response projected by current generation global climate models.

“These changes suggest that arid regions have become drier and high rainfall regions have become wetter in response to observed global warming,” said Durack, a post-doctoral fellow at Lawrence Livermore National Laboratory.

Scientists monitor salinity changes in the world’s oceans to determine where rainfall has increased or decreased. “It provides us with a gauge — a method of monitoring how large-scale patterns of rainfall and evaporation (the climate variables we care most about) are changing,” Durack said.

With a projected temperature rise of 3 degrees Celsius by the end of the century, the researchers estimate a 24 percent acceleration of the water cycle is possible.

[JR: Actually the projected warming by century's end is closer to 5°C -- see review of literature here -- which would yield a stunning 40% acceleration of the water cycle.]

Scientists have struggled to determine coherent estimates of water cycle changes from land-based data because surface observations of rainfall and evaporation are sparse. According to the team, global oceans provide a much clearer picture.

“The ocean matters to climate — it stores 97 percent of the world’s water; receives 80 percent of all surface rainfall, and it has absorbed 90 percent of the Earth’s energy increase associated with past atmospheric warming,” said co-author, Richard Matear of CSIRO’s Wealth from Oceans Flagship.

“Warming of the Earth’s surface and lower atmosphere is expected to strengthen the water cycle largely driven by the ability of warmer air to hold and redistribute more moisture.”

He said the intensification is an enhancement in the patterns of exchange between evaporation and rainfall, and with oceans accounting for 71 percent of the global surface area, the change is clearly represented in ocean surface salinity patterns.

In the study, the scientists combined 50-year observed global surface salinity changes with changes from global climate models and found “robust evidence of an intensified global water cycle at a rate of about 8 percent per degree of surface warming,” Durack said.

Durack said the patterns are not uniform, with regional variations agreeing with the ‘rich get richer’ mechanism, where wet regions get wetter and dry regions drier.

He said a change in freshwater availability in response to climate change poses a more significant risk to human societies and ecosystems than warming alone.

“Changes to the global water cycle and the corresponding redistribution of rainfall will affect food availability, stability, access and utilization,” Durack said.

Susan Wijffels, co-chair of the global Argo project and a co-author on the study, said maintenance of the present fleet of around 3,500 profilers is critical to observing continuing changes to salinity in the upper oceans. More
