"In a sustainable community, resource consumption is balanced by resources assimilated by the ecosystem. The sustainability of a community is largely determined by the web of resources providing its food, fiber, water, and energy needs and by the ability of natural systems to process its wastes. A community is unsustainable if it consumes resources faster than they can be renewed, produces more wastes than natural systems can process or relies upon distant sources for its basic needs."

Could big bills from extreme weather drive climate action?

LONDON (Thomson Reuters Foundation) – Could the growing costs of damage from extreme weather – in rich countries as well as poor – be the push that finally drives action on climate change?

Worst-in-a-decade flooding that swept through Germany as U.N. climate talks took place there this month will cost Germany’s government and its insurance companies up to $8 billion, experts estimate. In the United States, the bill for recovery from Hurricane Sandy is estimated at more than $50 billion, with agricultural losses from that country’s widespread drought last year even more costly.

“When you add up what all the extreme weather events cost last year (in the United States), it’s in excess of $250 billion,” said Rachel Kyte, vice president for sustainable development at the World Bank. “You’re talking about economic devastation that at some point is going to start hitting.”

So far, such heavy losses have not led to widespread political support for action on climate change in the United States, or other hard-hit countries. But a new report from the World Bank on the expected impacts of climate shifts suggests that so-called “loss and damage” from extreme weather is just starting, and the costs – in lives, economic damage and even potentially political stability – could rise dramatically around the world.

In South Asia, the once-regular Asian monsoon is growing less predictable, leading to deepening concerns that shifts could affect the food security and lives of 1.6 billion people. This year, the monsoon arrived almost a month early, causing severe flooding in some parts of India. At other times it has come late, leading to widespread power blackouts as desperate farmers switch on irrigation pumps, said Erick Fernandes, an adviser on climate change and natural resources for the World Bank.

Worsening drought in the Amazon threatens rainfall in food-producing areas of South America as far south as Argentina, he said, during a seminar on the World Bank report at the offices of the International Institute for Environment and Development (IIED) in London.

Brazil’s crops – which are widely exported to other countries as well as feeding Brazilians – are 95 percent rainfed, Fernandes said, and the country relies heavily on hydropower for its energy.

Ocean acidification, as the world’s seas absorb excess carbon dioxide in the atmosphere, has risen by 30 percent from pre-industrial times, the seminar heard. Acidification could prevent many shellfish from growing shells while an expected global temperature rises of at least 4 degrees Celsius would kill most coral reefs around the world, threatening tourism income and leaving coasts now protected by reefs more vulnerable to storms.

The Caribbean alone earns $5 billion a year from its coral reefs, Fernandes said.

TWO DEGREES HOTTER

Much of southern and southwest Africa is expected to see worsening drought by 2030 that could make growing maize – the region’s staple – impossible in 40 percent of the area it is now cultivated, the report said. Rising carbon dioxide in the atmosphere is also likely to turn many of Africa’s grass savannahs to brushy woodlands, affecting pastoralists.

In Southeast Asia, where coastal cities are seeing a big population surge, particularly in informal settlements, rising temperatures are expected to make life extremely uncomfortable for those without access to air conditioning, and to drive a serious increase in the severity of storms that could flood homes and workplaces – as happened in Thailand in 2011, said Fernandes.

Such shifts, besides causing huge financial losses, are likely to force a complete revamp of existing development plans.

“The development paradigm we’ve been peddling for years, that it’s easier to deal with the poor in urban settings than rural, because they’re easier to find and reach with services” may now be wrong, Kyte said.

“This report says that perhaps the most dangerous place to be if you’re poor is in the slums of a southeast Asian city.”

Changes are coming faster than expected, Fernandes said, noting that there was now a chance that a 4 degree Celsius rise in temperatures could arrive by 2060, and that “we could experience a 2-degree (hotter) world in our lifetimes”.

The increasingly extreme weather of recent years is the result of a 0.8 degree Celsius rise in the world’s temperature since pre-industrial times, which suggests that “even 2 degrees is not going to be a picnic”, he said.

Saleemul Huq, director of the International Centre for Climate Change and Development in Bangladesh, and a senior fellow at the IIED, said he saw the World Bank report as “all about loss and damage” – a relatively new term that describes the costs associated with failure to reduce or adapt to climate change.

Who might pay those costs remains a huge political question. Rich countries at the U.N. climate talks have so far refused to accept any liability for their higher carbon emissions, fearing it could lead to them having to pay billions in compensation, experts say.

That suggests many countries, companies and communities will be asked to shoulder the rising costs of extreme weather themselves – and those costs could lead to growing pressure for action, experts predicted. More

How do you feed 9 billion people?

An international team of scientists has developed crop models to better forecast food production to feed a growing population – projected to reach 9 billion by mid-century – in the face of climate change.


In a paper appearing in Nature Climate Change, members of the Agricultural Model Intercomparison and Improvement Project unveiled an all-encompassing modeling system that integrates multiple crop simulations with improved climate change models. AgMIP’s effort has produced new knowledge that better predicts global wheat yields while reducing political and socio-economic influences that can skew data and planning efforts, said Bruno Basso, Michigan State University ecosystem scientist and AgMIP member.

“Quantifying uncertainties is an important step to build confidence in future yield forecasts produced by crop models,” said Basso, with MSU’s geological sciences department and Kellogg Biological Station. “By using an ensemble of crop and climate models, we can understand how increased greenhouse gases in the atmosphere, along with temperature increases and precipitation changes, will affect wheat yield globally.”

The improved crop models can help guide the world’s developed and developing countries as they adapt to changing climate and create policies to improve food security and feed more people, he added.


Basso, part of MSU’s Global Water Initiative, and his team of researchers developed the System Approach for Land-Use Sustainability model. SALUS is a new generation crop tool to forecast crop, soil, water, nutrient conditions in current and future climates. It also can evaluate crop rotations, planting dates, irrigation and fertilizer use and project crop yields and their impact on the land.

SALUS was initially designed by Joe Ritchie, MSU emeritus distinguished professor. Basso continued Ritchie’s work and added new features to better predict the impact of agronomic management on crop yield over space and time.


“We can change the scenarios, run them simultaneously and compare their outcomes,” Basso said. “It offers us a great framework to easily compare different land-management approaches and select the most efficient strategies to increase crop yield and reduce environmental impact such as nitrate leaching and greenhouse gas emission.”

For the study, the team looked at simulated yield from 27 different wheat crop models. Through SALUS, Basso forecastedthe impact of changes in temperature, precipitation and CO2 emissions on wheat yield from contrasting environment across the planet.

SALUS has been employed in several other projects monitoring grain yield and water use in water-sensitive areas, such as the Ogallala aquifer (spanning from South Dakota to Texas), Siberia, India and Africa. More

Istanbul: Here I come

I am off to Istanbul tomorrow to join the Climate Reality Leadership Corps with former Vice-President Al Gore. I want to help change the world and raise awareness of climate change. After four years of trying I have finally been invited to undertake the training.

All around the world, members of the Climate Reality Leadership Corps trained by Chairman and former Vice President Al Gore are standing up and making a difference on the climate crisis. They’re leading by example, speaking to their communities about how climate change affects their daily lives—and what we can do to solve it. They’re appearing in the media, activating social networks, and—most of all—inspiring people everywhere to join us in confronting the defining issue of our time.


I have not been in Istanbul since 1976 so it will be good to be back and revisit some of the wonderful places to see. I am staying in the old city close to the Blue Mosque. One of the other places I want to see is the Basilica Cistern given my interest in water harvesting and storage.

This cathedral-size cistern is an underground chamber approximately 138 metres (453 ft) by 64.6 metres (212 ft)[5] - about 9,800 square metres (105,000 sq ft) in area - capable of holding 80,000 cubic metres (2,800,000 cu ft) of water. The ceiling is supported by a forest of 336 marble columns, each 9 metres (30 ft) high, arranged in 12 rows of 28 columns each spaced 4.9 metres (16 ft) apart. The capitals of the columns are mainly Ionic and Corinthianstyles, with the exception of a few Doric style with no engravings. One of the columns is engraved with raised pictures of a Hen's Eye, slanted braches, and tears. This column resembles the columns of the Triumphal Arch of Theodosius I from the 4th century (AD 379-395), erected in the 'Forum Tauri' Square. Ancient texts suggest that the tears on the column pay tribute to the hundreds of slaves who died during the construction of the Basilica Cistern. The majority of the columns in the cistern appear to have been recycled from the ruins of older buildings (a process called 'spoliation'), likely brought to Constantinople from various parts of the empire, together with those that were used in the construction of Hagia Sophia. They are carved and engraved out of various types of marble and granite.[6]

Fifty-two stone steps descend into the entrance of the cistern. The cistern is surrounded by afirebrick wall with a thickness of 4 metres (13 ft) and coated with a waterproofing mortar. The Basilica Cistern's water came from the Eğrikapı Water Distribution Center in the Belgrade Forest, which lie 19 kilometres (12 mi) north of the city. It traveled through the 971 metres (3,186 ft)-long Valens (Bozdoğan) Aqueduct, and the 115.45 metres (378.8 ft)-long Mağlova Aqueduct, which was built by the Emperor Justinian.[7]

The cistern has the capacity to store 100,000 tons of water, despite being virtually empty today with only a few feet of water lining the bottom.

The weight of the cistern lies on the columns by means of the cross-shaped vaults and round arches of its roof.


The Basilica Cistern has undergone several restorations since its foundation. The first of the repairs were carried out twice during the Ottoman State in the 18th century during the reign of Ahmed III in 1723 by the architect Muhammad Agha of Kayseri. The second major repair was completed during the 19th century during the reign of Sultan Abdulhamid II (1876–1909). Cracks to masonry and damaged columns were repaired in 1968, with additional restoration in 1985 by the Istanbul Metropolitan Museum. During the 1985 restoration, 50,000 tons of mud were removed from the cisterns, and a platforms built throughout to replace the boats once used to tour the cistern. The cistern was opened to the public in its current condition on 9 September 1987. In May 1994, the cistern underwent additional cleaning.

I believe that water security is going to be a large issue in the future and have been unfertaking a sturdy of of traditional methods of harvesting and storing water, methods with do not require huge amounts of energy.

Our Name and URL

Water is the essence of sustainability in an arid climate and hence I have named this blog in honor of this amazing and ancient Iranian method for transporting water.

A qanāt (from Arabic: قناة, in Persian: کاریز kariz) is a water management system used to provide a reliable supply of water for human settlements and irrigation in hot, arid and semi-arid climates.

Qanat Niavaran in Iran

Qanats are also called kārīz (or kārēz from Persian: كاريز) (Iran, Afghanistan, Pakistan and Central Asia, derived from Persian: كاهریز), kahan(from Persian: کهن), kahriz/kəhriz (Azerbaijan); khettara (Morocco); galería (Spain);falaj (United Arab Emirates and Oman); Kahn (Baloch) or foggara/fughara (North Africa). Alternative terms for qanats in Asia and North Africa are kakuriz, chin-avulz, and mayun. Common variants of qanat in English include kanat, khanat, kunut, kona,konait, ghanat, ghundat.

The qanat technology is known to have been developed by the Persian people sometime in the early 1st millennium BC and to have spread from there slowly west- and eastward.

The value of a qanat is directly related to the quality, volume and regularity of the water flow. Much of the population of Iran and other arid countries in Asia and North Africa historically depended upon the water from qanats; the areas of population corresponded closely to the areas where qanats are possible. Although a qanat was expensive to construct, its long-term value to the community, and thereby to the group that invested in building and maintaining it, was substantial.1

Water is the first sustainer of life, human life, wild life and the biosphere. It sustains agriculture and thereby food security. The purpose of this blog is to advocate, teach and demonstrate holistic ways of designing human environments and creating self sustaining communities using Permaculture techniques.
