Food Supply Notes

While the course on World Food Supply: A Famine in Our Future will not be offered at OLLI, I have continued to collect materials and read about the subject. The other day the Guardian from the UK had a disturbing article Food Prices May Rise Up to 20%, Warns UN. A combination of factors, most of them related to climate, have resulted in poor grain harvests in various places. We have already noted here the effects of drought on Russian grain production, long-term drought in Africa and the devastation of agricultural land in Pakistan as a consequence of flooding. Crops in parts of North America were good, but increased demand for maize (corn) and other food crops for bio-fuels adds a great deal of uncertainty to price predictions. Added together, those factors lead to a decline in the world's supply of basic food and feed grains and promise to drive prices up. The increase in food prices in Africa and some of the poorer parts of Asia are all but certain to lead to increased hunger, though for the moment starvation and famine would appear to be over the horizon. It is quite worrisome, and it will be more so should the 2011 growing season in the Southern Hemisphere, including the grain producing areas of South America and Australia, produce poor yields.

On a loosley related issue, I am a great fan of bargain bins and used book sales. The other day I was at a local branch of one of the huge bookstore chains and happened on remaindered copy of a volume which I find fascinating, an encyclopedia of the world's food plants Edible: An Illustrated Guide to the World's Food Plants (Washington, DC: National Geographic. ISBN 978-1-4262-0372-5 for the North American edition of a book that was originally published in Australia). With the National Geographic's (should really be called the National Photographic!) signature color photography, the book is an excellent guide to the what, where, and why of world food plants and great fun to thumb through or to use as a reference to look up some unusual food plant or another.

Pakistan Flooding

Pakistan late Summer 2010

For a variety of reasons I have been a little obsessed with the floods of the 2010 summer monsoon season in Pakistan. My original idea had been to use Pakistan, a country very much in the news, as a central case study in the water resources course with the idea that the country is chronically short of water and subject to political pressures internally and from India related to water supply and use. Then a few months before the course began Pakistan was hit with excess rainfall and flooding of catastrophic levels. I decided it was wisest to severeky curtail the use of Pakistan as a case. Should I teach the course again, I will have the prospective of time to examine the issue of 2010's flooding, its potential links to global climate change, and the meaning of it to a country usually suffering from drought, or worried about a lack of water. Meanwhile, NASA's Earth Observatory has posted a fine view of the flooded area from space and a brief, but as almost always concise and informative description of that photo in "Flooding in Pakistan," well worth a look!

Treaties and Compacts

Boundary Waters of Canada and the United States

On Wednesday the question was raised "What is the difference between a treaty and a compact?" I did not have a good answer at the time, and having devoted some research effort to the issue since, I still have not found a difference of consequence for most purposes, though there appears to be one of usage in the United States. In the dictionaries I have consulted, including paper ones on my shelves and online ones, there is virtually no difference in definition of the two terms, both being defined as agreements between individuals or states to resolve conflicts.

In the US the word "Compact" seems to be mostly used for agreements between states as in the "Great Lakes--St. Lawrence River Basin Water Resources Compact is a legally binding interstate compact among the U.S. states of Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania and Wisconsin. The compact details how the states manage the use of the Great Lakes Basin's water supply and builds on the 1985 Great Lakes Charter and its 2001 Annex. The compact is the means by which the states implement the governors' commitments under the Great Lakes-St. Lawrence River Basin Sustainable Water Resources Agreement that also includes the Premiers of Ontario and Quebec." (quoted from Wikipedia entry). Of course there is an international component as two Canadian Provinces are also involved, though neither the US Federal Government nor the Government of Canada appear to be direct parties to the Compact.

Treaty, on the other hand, seems to be used in the US to mean an agreement between the Federal Government and a foreign country (or countries). One example is the longstanding Boundary Waters Treaty between the United States and Great Britain (acting for Canada) signed in 1909 and ratified the next year. Creating an International Joint Commission of the two national states, the treaty is an agreement to provide mechanisms for resolution of disputes over the rather numerous water issues that arise between them. A great number of streams cross the boundary, including two huge ones in the West, the Columbia and the Yukon. The Great Lakes - St. Lawrence River Basin is a large share of the boundary waters and the most important watershed for the economies of the Canada and the United States, and it is part of the zone covered by the treaty. The Compact noted above is apparently a response to the Treaty at the level of states and provinces which have great responsibilities for water issues in their respective countries.

This is a none too satisfactory response to the question raised, and the difference between treaties and compacts is one I shall devote some additional effort to leaning about once I have completed a series of projects which are more pressing at the moment.

Dams III - Dam Removal

As they age, fill with silt, or water resource management priorities change, a large number of dams have been slated for removal. Most of those removed and proposed for removal have been smallish. The Elwha Dam, a decommissioned hydroelectric facility, inside the boundaries of Olympic National Park (the dam was built before the park was created) in the northwest corner of the continental United States is the largest dam to date to be put forth as a candidate for removal, and in September 2011 removal activity is scheduled to begin.

Removing a dam is very nearly as complicated as erecting one. Careful plans are necessary in order not to do great damage downstream. Fortunately the Elwha is a large river in flow but a short one, and the dam is only a few kilometers from its mouth into the Pacific at the Strait of Juan de Fuca. There is not much economic activity or infrastructure subject to damage downstream from the dam, making the removal problem a little less complex than it would be for most dams of comparable size.

The blog "On Water" from the Water Resources Center Archive at the University of California, Berkeley (my graduate alma mater) is an extremely valuable resource for materials on water issues. Its primary focus is water in California and nearby western states, buts its coverage goes well outside the limits of that state and region. On 28 October it published a listing of links to sources on dam removal.

Dams II - Belo Monte Dam in Brasil

Belo Monte Dam Proposal

Source: International Rivers

Last session I mentioned recently learning of a huge dam, slated to be the third largest on earth, cleared to begin construction, but I could not remember which river or what country. It is the Belo Monte Dam on the Xingu River in the State of Pará in Brasil. It is almost exclusively a hydroelectric project and will attempt to capture some of the energy of the Xingu, one of the world's longer and larger rivers by rate of flow and the final huge tributary of the Amazon before it enters the Atlantic. As I noted "dictators love dams," and the original proposal for the Belo Monte Dam dates to the military dictatorship that misgoverned Brasil a generation ago. Like many bad ideas, however, the proposal did not die when the dictatorship ended.

One of over a hundred proposed hydroelectric dams in the Amazon basin of Brasil, when and if constructed, the Belo Monte Dam will flood a vast area of biologically diverse tropical rain forest and displace a large number of first nations people. Its proposed construction has generated a huge controversy. Various organizations within Brasil (a source from Brasil in English) and outside like the non-profit International Rivers have protested the construction and are likely to continue doing so even though the dam project appears to have cleared the final legal hurdle. It will be a vastly expensive project, and one of the expenses is a requirement that the winning bidders pay the equivalent of almost a billion US dollars to create national parks, ecological reserves, and homes for the 20-40,000 people who will be displaced by flooding when the reservoir is filled. The director James Cameron and members cast of the cartoon Avatar have been among the most vocal opponents of the dam outside Brasil, and they have produced a film narrated by the actress Sigourney Weaver to raise awareness of their protest.

A few days ago Brasil elected a new president, its first female head of government. It is unlikely but possible that Dilma Roussef will repudiate the policy of her predecessor and patron, the immensely popular current president Luiz Inácio "Lula" da Silva and halt construction now that courts have granted legal approval. We shall have to wait and see.
