Allan Savory: How to fight desertification and reverse climate change

"Desertification is a fancy word for land that is turning to desert," begins Allan Savory in this quietly powerful talk. And it's happening to about two-thirds of the world's grasslands, accelerating climate change and causing traditional grazing societies to descend into social chaos.Savory has devoted his life to stopping it. He now believes — and his work so far shows — that a surprising factor can protect grasslands and even reclaim degraded land that was once desert.

Allan Savory works to promote holistic management in the grasslands of the world.

Climate change is clear and present danger, says landmark US report

Climate change has moved from distant threat to present-day danger and no American will be left unscathed, according to a landmark report due to be unveiled on Tuesday.

The National Climate Assessment, a 1,300-page report compiled by 300 leading scientists and experts, is meant to be the definitive account of the effects of climate change on the US. It will be formally released at a White House event and is expected to drive the remaining two years of Barack Obama's environmental agenda.

The findings are expected to guide Obama as he rolls out the next and most ambitious phase of his climate change plan in June – a proposal to cut emissions from the current generation of power plants, America's largest single source of carbon pollution.

The White House is believed to be organising a number of events over the coming week to give the report greater exposure.

"Climate change, once considered an issue for a distant future, has moved firmly into the present," a draft version of the report says. The evidence is visible everywhere from the top of the atmosphere to the bottom of the ocean, it goes on.

"Americans are noticing changes all around them. Summers are longer and hotter, and periods of extreme heat last longer than any living American has ever experienced. Winters are generally shorter and warmer. Rain comes in heavier downpours, though in many regions there are longer dry spells in between."

The final wording was under review by the White House but the basic gist remained unchanged, scientists who worked on the report said.

On Sunday the UN secretary-general, Ban Ki-moon, said the world needed to try harder to combat climate change. At a meeting of UN member states in Abu Dhabi before a climate change summit in New York on 23 September, Ban said: "I am asking them to announce bold commitments and actions that will catalyse the transformative change we need. If we do not take urgent action, all our plans for increased global prosperity and security will be undone."

Gary Yohe, an economist at Wesleyan University and vice-chair of the NCA advisory committee, said the US report would be unequivocal that the effects of climate change were occurring in real-time and were evident in every region of the country.

"One major take-home message is that just about every place in the country has observed that the climate has changed," he told the Guardian. "It is here and happening, and we are not cherrypicking or fearmongering."

The draft report notes that average temperature in the US has increased by about 1.5F (0.8C) since 1895, with more than 80% of that rise since 1980. The last decade was the hottest on record in the US.

Temperatures are projected to rise another 2F over the next few decades, the report says. In northern latitudes such as Alaska, temperatures are rising even faster.

"There is no question our climate is changing," said Don Wuebbles, a climate scientist at the University of Illinois and a lead author of the assessment. "It is changing at a factor of 10 times more than naturally."

Record-breaking heat – even at night – is expected to produce more drought and fuel larger and more frequent wildfires in the south-west, the report says. The north-east, midwest and Great Plains states will see an increase in heavy downpours and a greater risk of flooding.

"Parts of the country are getting wetter, parts are getting drier. All areas are getting hotter," said Virginia Burkett, chief scientist for global change at the US Geological Survey. "The changes are not the same everywhere."

Those living on the Atlantic seaboard, Gulf of Mexico, and Alaska who have weathered the effects of sea level rise and storm surges can expect to see more. Residents of coastal cities, especially in Florida where there is already frequent flooding during rainstorms, can expect to see more. So can people living in inland cities sited on rivers.

Some changes are already having a measurable effect on food production and public health, the report will say.

John Balbus, senior adviser at the National Institute of Environmenal Health Science and a lead author of the NCA report, said rising temperatures increased the risk of heat stroke and heat-related deaths.

Eugene Takle, convening lead author of the agriculture chapter of the NCA report, and director of the Climate Science programme at Iowa State University, said heatwaves and changes in rainfall had resulted in a levelling off in wheat and corn production and would eventually cause declines.

In California, warmer winters have made it difficult to grow cherries. In the midwest, wetter springs have delayed planting. Invasive vines such as kudzu have spread northward, from the south to the Canadian border.

Some of the effects on agriculture, such as a longer growing season, are positive. But Takle said: "By mid-century and beyond the overall impacts will be increasingly negative on most crops and livestock."

The assessments are the American equivalent of the UN's Intergovernmental Panel on Climate Change (IPCC) reports. This year's report for the first time looks at what America has done to fight climate change or protect people from its consequences in the future.

Under an act of Congress the reports were supposed to be produced every four years, but no report was produced during George W Bush's presidency. More

Pakistan has only 30 days of water reserves - researchers

ISLAMABAD, Pakistan (Thomson Reuters Foundation) – Inadequate planning is exposing Pakistan to water-related threats from climate change and putting the country’s agriculture, industry and hydropower at risk, water experts say.

Speaking at a water summit in Pakistan recently, they said the country desperately needs more reservoirs to increase its water storage capacity, and they called for conservation awareness campaigns, the introduction of drought-tolerant crop varieties and more economical irrigation.

“The country is gravely vulnerable to water-related (effects) of the changing weather patterns,” said Pakistan’s minister for planning, development and reform, Ahsan Iqbal, in a keynote address at the summit in the nation’s capital.

In December, the World Resources Institute ranked Pakistan among the 36 most water-stressed countries in the world.

Iqbal said that Pakistan needs a minimum storage capacity of 40 percent of the around 115 million acre-feet of water available in the Indus river system throughout the year. But the country’s storage capacity is only 7 percent and is decreasing due to sediment build-up in reservoirs.

This gives Pakistan a stored water supply, adequate to meet its needs, of just 30 days. By contrast, “carryover capacity” in other countries ranges from 200 days in India to 1,000 days in Egypt, he said.

“In Pakistan, planners and policy makers across different sectors, including agriculture and industry, energy and health now have ... a daunting challenge before them of increasing the country’s water storage capacity,” Iqbal said.

The minister urged the finance ministry to explore funding avenues for new water storage projects to boost storage capacity. Many of these are hydroelectric dams, which would also produce power.

THREATS TO HYDROPOWER, AGRICULTURE

But Pakistan Water Partnership’s country director, Pervaiz Amir, warned that if climate change leads to lower water flows in the northwest of the country, it would cut the amount of hydroelectricity that can be produced.

More variable rainfall and glacier melt in the face of climate change also means that agriculture, which he said accounts for over 96 percent of the country’s water consumption, will be affected, Amir said.

Without more facilities to divert and store water, heavy rainfall and flooding in some parts of the country will continue to damage crops, increase soil erosion and delay planting and harvesting, he said.

Pakistan ranks ninth among countries most affected by floods, according to UN-Water’s World Water Development Report.

Arun Shrestha, a senior climate change specialist at the International Centre for Integrated Mountain Development (ICIMOD), said that many South Asian countries lack preparedness for water-related hazards, including flood, droughts and glacial lake outburst floods, and instead focus mainly on post-disaster relief.

What is “more appalling,” he said, is that climate change is dealt with as a separate problem rather than integrated into planning for water-related areas of the government and economy including agriculture, industry, health and energy.

Shrestha urged South Asian countries to include disasters attributable to climate change in their respective water-related planning and policies.

He called for them to analyse their vulnerabilities to increasingly frequent flooding, droughts and glacial lake outburst floods, and to share the findings with each other to develop a regional action plan for dealing with climate-related disasters.

Shrestha underlined the need for regional coordination between government agencies so that river basins can be managed more efficiently, for example by sharing data about river flows.

Stephen Davies, a senior research fellow at the International Food Policy Research Institute, said that water, food and energy are closely interconnected, yet energy models do not properly address water constraints in South Asia and other regions.

Industrial growth and accelerating urbanisation are creating greater demand for energy, he said, but efforts to expand hydropower generation are being hampered by the shrinking availability of water.

Limitations on water availability also are impacting food production to meet the country’s galloping population growth, he added.

Chief executive of LEAD Pakistan and climate policy expert Tauqeer Ali Sheikh urged policymakers to incorporate the interdependence of water, food and energy into their planning.

In South Asia, “energy planning is often made without taking into account possible changes in water availability due to climate change or other water competing uses,” he pointed out. More

Saleem Shaikh and Sughra Tunio are climate change and development reporters based in Islamabad, Pakistan.

Cary Fowler on Food Security - TED Talk

Cary Fowler served as the Executive Director of the Global Crop Diversity Trust from 2005 to 2012.^[8] The trust's mandate is to ensure "the conservation and availability of crop diversity for food security worldwide." Fowler was influential in the creation of the Svalbard Global Seed Vault, which currently houses samples of more than 783,000 distinct crop varieties. He stepped down as Executive Director of the trust in late 2012 but continues to serve in an advisory role and chairs the International Advisory Council of the Svalbard Global Seed Vault.^[4][8]

Working with partner genebanks in 71 countries during Fowler's tenure as Executive Director, the Trust helped rescue 83,393 unique crop varieties from extinction. It sponsored more than 40 projects to screen crop collections for important traits such as heat and drought tolerance. In partnership with the USDA, a state-of-the-art genebank management system ("GRIN-Global") was developed and made available to 38 genebanks internationally, and the first ever global portal to accession (sample) level information (Genesys)^[9] was launched. The Trust's endowment grew more than $100 million to $134 million, and total funds raised surpassed $200 million.^[10][11]

By the end of Fowler's tenure, the Trust concluded three major agreements intended to protect and conserve crop diversity: with the Millennium Seed Bank of Kew Gardens,^[12] the indigenous communities in the Andes,^[13] and the international genebanks of the Consultive Group on International Agricultural Research (CGIAR).^[14]

One example given here is for South Asia where we must pay attention from a food security perspective. Editor
