What If Experts Are Wrong On World Population Growth?
›September 22, 2011 // By Wilson Center StaffThe original version of this article, by Carl Haub, appeared on Yale Environment 360.
In a mere half-century, the number of people on the planet has soared from 3 billion to 7 billion, placing us squarely in the midst of the most rapid expansion of world population in our 50,000-year history – and placing ever-growing pressure on the Earth and its resources.
But that is the past. What of the future? Leading demographers, including those at the United Nations and the U.S. Census Bureau, are projecting that world population will peak at 9.5 billion to 10 billion later this century and then gradually decline as poorer countries develop. But what if those projections are too optimistic? What if population continues to soar, as it has in recent decades, and the world becomes home to 12 billion or even 16 billion people by 2100, as a high-end UN estimate has projected? Such an outcome would clearly have enormous social and environmental implications, including placing enormous stress on the world’s food and water resources, spurring further loss of wild lands and biodiversity, and hastening the degradation of the natural systems that support life on Earth.
It is customary in the popular media and in many journal articles to cite a projected population figure as if it were a given, a figure so certain that it could virtually be used for long-range planning purposes. But we must carefully examine the assumptions behind such projections. And forecasts that population is going to level off or decline this century have been based on the assumption that the developing world will necessarily follow the path of the industrialized world. That is far from a sure bet.

Water: Asia’s New Battleground
›“Asia faces a daunting water crisis,” warns Brahma Chellaney, professor at the Center for Policy Research (New Delhi) and author of the new book, Water: Asia’s New Battleground. It is a crisis that imperils the region’s economic and political rise, and that deepens environmental risk in a part of the world marked by melting glaciers and densely populated coastal areas.
In his book, Chellaney, regarded as one of India’s most distinguished strategists, surveys the water landscape across Asia; examines the security implications of water-based territorial disputes; and offers policy recommendations to help prevent water conflict. On September 12, Chellaney spoke about Water at a Wilson Center event organized by the Asia Program and co-sponsored by the China Environment Forum and Environmental Change and Security Program. Steven Solomon, a journalist and author who last year published Water: The Epic Struggle for Wealth, Power, and Civilization, offered commentary.
According to Chellaney, Water “fills a void in the literature” by, for the first time, focusing on water issues across the entire continental region of Asia – an immense expanse that includes not only Northeast, Southeast, and South Asia, but also Central Asia and the Middle East. The book, he explained, defines Asia “as it looks on a map.”
The World’s Dam Center
What drives the water crisis in this vast region? One factor is population. Asia is the world’s largest and most populous continent but also the most water-deficient; its freshwater levels per capita are one-third those of Europe’s, and slightly less than Africa’s. Another is tied to economic development. Asia is the world’s fastest developing continent, yet its most rapidly developing nations, particularly India and China, are already afflicted by serious water challenges.
Rising income levels and attendant growth in consumption rates are additional drivers. Asians are consuming more resources, including meat, which requires prodigious amounts of water to produce. A fourth factor is intensive irrigation. Seventy percent of the world’s total irrigation originates in Asia, and 80 percent of the region’s “water withdrawals” are allocated to agriculture. (The latter figure is only 30 percent in Europe.) Such large-scale irrigation has enabled Asia to evolve from “a land of recurrent famine” to a major food exporter, yet it has also spawned ruinous agricultural conditions such as waterlogging and soil salinity.
Chellaney contended that Asia’s water ills can also be attributed to the “large-scale impoundment of water” by dams, barrages, and other storage-creating structures. Asia is the world’s “dam center,” he said, with China boasting half the world’s dams and now planning to construct “mega dams,” including one “higher than the Eiffel Tower.” Impounding water triggers riverwater depletion, which in turns promotes “the reckless use” of sub-surface groundwater resources, said Chellaney. With water tables plummeting, millions of groundwater pumps are depleting what used to be a pristine and plentiful resource.
“We Need Better Politics”
In a region rife with transboundary rivers yet devoid of mechanisms to promote transboundary water-sharing, Asia’s water troubles pose grave geopolitical risks.
According to Chellaney, “water wars” are already being waged across the region via non-military means, fostering mistrust and hampering efforts toward greater cooperation. He argued that in order to forestall water conflict, Asia must develop a set of norms on shared resources based on the 1997 UN Convention on the Non-Navigational Uses of International Watercourses – the only available instrument for international water management. Chellaney also called for the creation of “inclusive water institutions,” that emphasize transparency and dispute settlements, and for the adoption of “holistic planning” on central and provincial governmental levels that aim for better water efficiency.
Playing devil’s advocate, Solomon faulted Chellaney for according insufficient attention to Asia’s crisis of energy – a resource that, he pointed out, is “extraordinarily water-intensive.” He also countered Chellaney’s criticism of dams by observing that Asia desperately needs storage – a deficiency that makes the region highly vulnerable to drought. And he questioned whether China’s dam-building activities on the Brahmaputra River truly imperil lower riparian India’s water security, noting that only 15 percent of the river’s flows entering India are impacted by Chinese dams.
Ultimately, Chellaney said, alleviating Asia’s water crisis will also require improving the region’s poor political environment. While Asian economies are coming together, its politics are more divided. Transboundary water cooperation – and any treaty meant to undergird it – cannot be expected to last if co-riparians do not get along. “We need better politics,” he concluded.

Backdraft: Minimizing Conflict in Climate Change Responses
›
“What are the conflicts or risks associated with response to climate change?” asked ECSP Director Geoff Dabelko at the Wilson Center on July 18. “How we respond to climate change may or may not contribute to conflict,” he said, but “at the end of the day, we need to do no harm.”

The Year of Drought and Flood
›August 1, 2011 // By Wilson Center StaffThe original version of this article, by Lakis Polycarpou, appeared on the Columbia Earth Institute’s State of the Planet blog.
On the horn of Africa, ten million people are now at risk as the region suffers the worst drought in half a century. In China, the Yangtze – the world’s third largest river – is drying up, parching farmers and threatening 40 percent of the nation’s hydropower capacity. In the U.S. drought now spreads across 14 states creating conditions that could rival the dust bowl; in Texas, the cows are so thirsty now that when they finally get water, they drink themselves to death.
And yet this apocalyptic dryness comes even as torrential springtime flooding across much of the United States flows into summer; even as half a million people are evacuated as water rises in the same drought-ridden parts of China.
It seems that this year the world is experiencing a crisis of both too little water and too much. And while these crises often occur simultaneously in different regions, they also happen in the same places as short, fierce bursts of rain punctuate long dry spells.
The Climate Connection
Most climate scientists agree that one of the likely effects of climate will be an acceleration of the global water cycle, resulting in faster evaporation and more precipitation overall. Last year, the Proceedings from the National Academy of Sciences published a study which suggested that such changes may already be underway: According to the paper, annual fresh water flowing from rivers into oceans had increased by 18 percent from 1994 to 2006. It’s not hard to see how increases in precipitation could lead to greater flood risk.
At the same time, many studies make the case that much of the world will be dramatically drier in a climate-altered future, including the Mediterranean basin, much of Southwest and Southeast Asia, Latin America, the western two-thirds of the United States among other places.

Second Generation Biofuels and Revitalizing African Agriculture
›In “A New Hope for Africa,” published in last month’s issue of Nature, authors Lee R. Lynd and Jeremy Woods assert that the international development community should “cut with the beneficial edge of bioenergy’s double-edged sword” to enhance food security in Africa. According to Lynd and Woods, Africa’s severe food insecurity is a “legacy of three decades of neglect for agricultural development.” Left out of the Green Revolution in the 1960s, the region was flooded with cheap food imports from developed nations while local agricultural sectors remained underdeveloped. With thoughtful management, bioenergy production on marginal lands unfit for edible crops may yield several food security benefits, such as increased employment, improved agricultural infrastructure, energy democratization, land regeneration, and reduced conflict, write the authors.The technological advancements of second-generation biofuels may ease the zero-sum tension between food production and bioenergy in the future, writes Duncan Graham-Rowe in his article “Beyond Food Versus Fuel,” also appearing last month in Nature. Graham-Rowe notes that current first-generation biofuel technologies, such as corn and sugar cane, contribute to rising food prices, require intensive water and nitrogen inputs, and divert land from food production by way of profitability and physical space. There is some division between second-generation biofuel proponents: some advocate utilizing inedible parts of plants already produced, while others consider fast-growing, dedicated energy crops (possibly grown on polluted soil otherwise unfit for human use) a more viable solution – either has the potential to reduce demand for arable land, says Graham-Rowe. “Advanced generations of biofuels are on their way,” he writes, it is just a matter of time before their kinks are worked out “through technology, careful land management, and considered use of resources.” -
In Rush for Land, Is it All About Water?
›July 26, 2011 // By Christina DaggettOver the past few years, wealthy countries with shrinking stores of natural resources and relatively large populations (such as China, India, South Korea, and the Gulf states) have quietly purchased huge parcels of fertile farmland in Africa, South America, and South Asia to grow food for export to the parent country. With staple food prices shooting up and food security projected to worsen in the decades ahead, it is little wonder that countries are looking abroad to secure future resources. But the question arises: Are these “land grabs” really about the food — or, more accurately, are they “water grabs”?
The Great Water Grab
With growing urban populations, an expanding middle class, and increasingly scarce arable land resources, some governments and investors are snapping up the world’s farmland. Some observers, however, have pointed out that these dealmakers might be more interested in the water than the land.
In an article from The Economist in 2009, Peter Brabeck-Letmathe, the chairman of Nestlé, claimed that “the purchases weren’t about land, but water. For with the land comes the right to withdraw the water linked to it, in most countries essentially a freebie that increasingly could be the most valuable part of the deal.”
Consider some of the largest investors in foreign land: China has a history of severe droughts (and recently, increasingly poor water quality); the Gulf nations of Saudi Arabia, Kuwait, Qatar, and Bahrain are among the world’s most water-stressed countries; and India’s groundwater stocks are rapidly depleting.
A recent report from the World Bank on global land deals highlighted the effect water scarcity is having on food production in China, South Asia, the Middle East, and North Africa, stating that “in contrast, Sub-Saharan Africa and Latin America have large untapped water resources for agriculture.”
Keeping Engaged and Informed
“The water impacts of any investment in any land deal should be made explicit,” said Phil Woodhouse of the University of Manchester during the recent International Conference on Global Land Grabbing, as reported by the New Agriculturist. “Some kind of mechanism is needed to bring existing water users into an engagement on any deals done on water use.”
At the same conference, Shalmali Guttal of Focus on the Global South cautioned, “Those who are taking the land will also take the water resources, the forests, wetlands, all the wild indigenous plants and biodiversity. Many communities want investments but none of them sign up for losing their ecosystems.”
With demand for water expected to outstrip supply by 40 percent within the next 20 years, water as the primary motivation behind the rush for foreign farmland is a factor worth further exploration.
Global Farming
According to a report from the Oakland Institute, nearly 60 million hectares (ha) of African farmland – roughly the size of France – were purchased or leased in 2009. With these massive land deals come promises of jobs, technology, infrastructure, and increased tax revenue.
In 2008 South Korean industrial giant Daewoo Logistics negotiated one of the biggest African farmland deals with a 99-year lease on 1.3 million ha of farmland in Madagascar for palm oil and corn production. The deal amounted to nearly half of Madagascar’s arable land – an especially staggering figure given that nearly a third of Madagascar’s GDP comes from agriculture and more than 70 percent of its population lives below the poverty line. When details of the deal came to light, massive protests ensued and it was eventually scrapped after president Marc Ravalomanana was ousted from power in a 2009 coup.
While perhaps an extreme example, the Daewoo/Madagascar deal nonetheless demonstrates the conflict potential of these massive land deals, which are taking place in some of the poorest and hungriest countries in the world. In 2009, while Saudi Arabia was receiving its first shipment of rice grown on farmland it owned in Ethiopia, the World Food Program provided food aid to five million Ethiopians.
Other notable deals include China’s recent acquisition of 320,000 ha in Argentina for soybean and corn cultivation – a project which is expected to bring in $20 million in irrigation infrastructure, the Guardian reports – and a Saudi Arabian company which has plans to invest $2.5 billion and employ 10,000 people in Ethiopia by 2020, according to Gambella Star News.
But governments in search of cheap food aren’t the only ones interested in obtaining a piece of the world’s breadbasket: Individual investors are also heavily involved, and the Guardian reports that U.S. universities and European pension funds are buying and leasing land in Africa as well.
The Future of Land and Water
Whatever the benefits or pitfalls, large-scale land deals around the world look set to continue. The world is projected to have 7 billion mouths to feed by the end of this year and possibly 10 billion plus by the end of the century.
Currently, agriculture uses 11 percent of the world’s land surface and 70 percent of the world’s freshwater resources, according to UNESCO. If and when the going gets tough, how will the global agricultural system respond? Whose needs come first – the host countries’ or the investing nations’?

Preparing for the Impact of a Changing Climate on U.S. Humanitarian and Disaster Response
›Climate-related disasters could significantly impact military and civilian humanitarian response systems, so “an ounce of prevention now is worth a pound of cure in the future,” said CNA analyst E.D. McGrady at the Wilson Center launch of An Ounce of Preparation: Preparing for the Impact of a Changing Climate on U.S. Humanitarian and Disaster Response. The report, jointly published by CNA and Oxfam America, examines how climate change could affect the risk of natural disasters and U.S. government’s response to humanitarian emergencies. [Video Below]
Connecting the Dots Between Climate Change, Disaster Relief, and Security
The frequency of – and costs associated with – natural disasters are rising in part due to climate change, said McGrady, particularly for complex emergencies with underlying social, economic, or political problems, an overwhelming percentage of which occur in the developing world. In addition to the prospect of more intense storms and changing weather patterns, “economic and social stresses from agricultural disruption and [human] migration” will place an additional burden on already marginalized communities, he said.
Paul O’Brien, vice president for policy and campaigns at Oxfam America said the humanitarian assistance community needs to galvanize the American public and help them “connect the dots” between climate change, disaster relief, and security.
As a “threat multiplier,” climate change will likely exacerbate existing threats to natural and human systems, such as water scarcity, food insecurity, and global health deterioration, said Vice Admiral Lee Gunn, USN (ret.), president of CNA’s Institute for Public Research. Major General Richard Engel, USAF (ret.), of the National Intelligence Council identified shifting disease patterns and infrastructural damage as other potential security threats that could be exacerbated by climate change.
“We must fight disease, fight hunger, and help people overcome the environments which they face,” said Gunn. “Desperation and hopelessness are…the breeding ground for fanaticism.”
U.S. Response: Civilian and Military Efforts
The United States plays a very significant role in global humanitarian assistance, “typically providing 40 to 50 percent of resources in a given year,” said Marc Cohen, senior researcher on humanitarian policy and climate change at Oxfam America.
The civilian sector provides the majority of U.S. humanitarian assistance, said Cohen, including the USAID Office of Foreign Disaster Assistance (OFDA) and the State Department’s Bureau of Population, Refugees, and Migration. These organizations provide leadership, funding, and food aid to developing countries in times of crisis, but also beforehand: “The internal rationale [of the Office of Foreign Disaster Assistance] is to reduce risk and increase the resilience of people to reduce the need for humanitarian assistance in the future,” said Edward Carr, climate change coordinator at USAID’s Bureau for Democracy, Conflict, and Humanitarian Assistance.
The U.S. military complements and strengthens civilian humanitarian assistance efforts by accessing areas that civilian teams cannot reach. The military can utilize its heavy lift capability, in-theater logistics, and command and control functions when transportation and communications infrastructures are impaired, said McGrady, and if the situation calls for it, they can also provide security. In addition, the military could share lessons learned from its considerable experience planning for complex, unanticipated contingencies with civilian agencies preparing for natural disasters.
“Forgotten Emergencies”
Already under enormous stress, humanitarian assistance and disaster response systems have persistent weaknesses, such as shortfalls in the amount and structure of funding, poor coordination, and lack of political gravitas, said Cohen.
Food-related aid is over-emphasized, said Cohen: “If we break down the shortfalls, we see that appeals for food aid get a better response than the type of response that would build assets and resilience…such as agricultural bolstering and public health measures.” Food aid often does not draw on local resources in developing countries, he said, which does little to improve long-term resilience.
“Assistance is not always based on need…but on short-term political considerations,” said Cohen, asserting that too much aid is supplied to areas such as Afghanistan and Iraq, while “forgotten emergencies,” such as the Niger food crisis, receive far too little. Furthermore, aid distribution needs to be carried out more carefully at the local scale as well: During complex emergencies in fragile states, any perception of unequal assistance has the potential to create “blowback” if the United States is identified with only one side of a conflict.
Engel added that many of the problems associated with humanitarian assistance will be further compounded by increasing urbanization, which concentrates people in areas that do not have adequate or resilient infrastructure for agriculture, water, or energy.
Preparing for Unknown Unknowns
A “whole of government approach” that utilizes the strengths of both the military and civilian humanitarian sectors is necessary to ensure that the United States is prepared for the future effects of climate change on complex emergencies in developing countries, said Engel.
In order to “cut long-term costs and avoid some of the worst outcomes,” the report recommends that the United States:
Cohen singled out “structural budget issues” that pit appropriations for protracted emergencies in places like Iraq, Afghanistan, and Darfur against unanticipated emergencies, like the 2010 earthquake in Haiti. Disaster-risk reduction investments are not a “budgetary trick” to repackage disaster appropriations but a practical way to make more efficient use of current resources, he said: “Studies show that the return on disaster-risk reduction is about seven to one – a pretty good cost-benefit ratio.”- Increase the efficiency of aid delivery by changing the budgetary process;
- Reduce the demand by increasing the resilience of marginal (or close-to-marginal) societies now;
- Be given the legal authority to purchase food aid from local producers in developing countries to bolster delivery efficiency, support economic development, and build agricultural resilience;
- Establish OFDA as the single lead federal agency for disaster preparedness and response, in practice as well as theory;
- Hold an OFDA-led biannual humanitarian planning exercise that is focused in addressing key drivers of climate-related emergencies; and,
- Develop a policy framework on military involvement in humanitarian response.
Edward Carr said that OFDA is already integrating disaster-risk reduction into its other strengths, such as early warning systems, conflict management and mitigation, democracy and governance, and food aid. However, to build truly effective resilience, these efforts must be tied to larger issues, such as economic development and general climate adaptation, he said.
“What worries me most are not actually the things I do know, but the things we cannot predict right now,” said Carr. “These are the biggest challenges we face.”

Tate Watkins, Short Sentences
Why Fund Both Farm Subsidies and Foreign Aid?
›June 27, 2011 // By Wilson Center StaffThe original version of this article, by Tate Watkins, appeared on the blog Short Sentences.
The USDA routinely disburses $10 billion to $30 billion a year in farm subsidies. President Obama has allocated $47 billion for the State Department and USAID for the next fiscal year (not including proposed expenditures for Afghanistan, Iraq, and Pakistan).*
Why does the U.S. simultaneously fund domestic agricultural subsidies and foreign aid? The policies oppose each other. When it comes to promoting development opportunities for farmers around the globe, one of USAID’s ostensible goals, the left hand of the U.S. binds its right.
The origin of agricultural subsidies goes back at least to the first Agricultural Adjustment Act, enacted in 1933 as an attempt to help Depression farmers cope. Today farm interests justify subsidies in name of food security or, since 9/11, national security. But it’s widely acknowledged that the pastoral American family farmer, the image that farm interests present to the American people when the merits of subsidies are debated, do not benefit most from agricultural subsidies. Large corporate farmers do.
