I. Resources and Population

A. Carrying Capacity vs Overpopulation

• Recent growth of resource consumption in AICs [Advance Industrial Countries] has dwarfed growth of demand in LDCs

• The issue isn't bodies, its consumption  

Zero Sum Game

• Define Zero Sum Game

Food Resources 4

Food Resources 5

ZERO SUM GAME

From Wikipedia, the free encyclopedia

• describes a situation in which one participant's gain (or loss) is exactly balanced by the losses (or gains) of the other participant(s).

• total gains of the participants and subtract the total losses then they will sum to zero.

• In layman's terms, in order for one person to win, another must lose.

ZERO SUM GAME

Is the world resource issue a zero sum game?

• What I have you don’t have

• What I have you can’t have

• Hint Marx implied a Zero sum game, Bill Gates and Milton Friedman don’t.

ZERO SUM GAME ???

Over Population/Consumption

• To play the "zero sum game" you need to know when you reach “zero” or full use, – at that we can only guess– this has been a moving target

due to technological advancement

Food Resources 8

ZERO SUM GAME ???

Over Population/Consumption• Consider that Overpopulation might

be: • an unwanted child • as much as an unsupportable child

• Over consumption might be a second automobile for someone in a nursing home as much as a Presidential candidate that doesn’t know how many homes he owns

• Basically we hope this isn’t a zero sum game

Optimum Population

• What is the Optimum Population for the world, USA, WA State.

• Start by estimating the current population for each

 Optimum Population

• What is it? -- its all in the eyes of the perceiver,

• Its the quagmire of sustainable development  – Everyone is for this – But no one can adequately describe it– We can only assert the negative

• What it isn’t

Food Resources 12

Optimum Population

• The Mayans thought their population was optimal until it collapsed

• What is sustainable energy use? Should all fossil fuels be banned? What about hydro dams (called “bridge power” by Patick McCully,

2003)?

Food Resources 13

Unfortunate Conclusion

Bottom Line• Everyone worries about the possibility of

the Zero Sum Game

• Everyone talks Sustainable Development

• No one knows what Optimum Population or Consumption is

II. Types of resources and their limits (Define terms)

• Resource Definition: If its presumed useable and finite (i.e. has a market/ “true price”), then its a resource– star-shine, not a resource (today) – air, not understood as a resource – However Viewsheds are a resource

Define Resource Amount

• What is the difference between a– Reserve– Projected Reserve– Resource

Food Resources 15

Food Resources 16

Measuring and Defining Resources

A. Reserves, Projected Reserves, (total) Resources

Reserves – known & available with current technology & at current prices (today)

Projected Reserves – based on expected future prices & technologies (tomorrow)

Resources – materials in the Environment that may someday be used (unknown if ever)

Example with Gold

Food Resources 17

Gold Ore

• Reserves – current mines and gold fields

• Projected Reserves – possible deeper and more difficult to extract ores, currently not profitable to mine

• Resources – includes things like sea water which has gold, but may never be economical to extract

Resource Type

Class exercise

•In the energy field give an example of a reserve, projected reserve, and resource

Global Fisheries Collapse Predicted

Pew Marine Conservation Fellows Co-Author Science Article on Impacts of biodiversity loss on ocean ecosystem services.November 06, 2006

A recent Science publication warns that the world will run out of seafood by 2048 if steep declines in marine species continue at current rates, based on a four-year study of catch data and the effects of fisheries collapses. The co-authors of the paper, written by an international group of ecologists and economists, include Pew Marine Conservation Fellows Carl Folke, Stephen Palumbi, and Enric Sala.

Global Fisheries Collapse Predicted

Details

The recent paper, published in the journal Science (Worm et al. 2006), predicts the global collapse (defined as fish catches dropping below 10 percent of historic catches) of all currently fished taxa by 2048. The prediction is based on a meta-analysis of published data in which the authors examined the effects of declining species diversity on marine ecosystem services. Results suggest that the loss of biodiversity in coastal ecosystems has led to the impairment of critical ecosystem services, such as the filtering services provided by suspension feeders and submerged vegetation that contribute to the maintenance of high water quality. The authors also used the United Nations Food and Agriculture Organization’s global catch database for the period from 1950 to 2003 to examine relationships between biodiversity and ecosystem services in 64 large marine ecosystems (greater than 150,000 square-km).

This analysis revealed that 29 percent of all fished species had collapsed by 2003 and ecosystems with the fewest species suffered the greatest rates of collapse. The authors note that large marine ecosystems with higher species diversity also recovered more quickly following periods of overexploitation, perhaps due to the improved abilities of fishers to switch among species, thus giving overexploited species the opportunity to recover. Finally, the authors examined relationships between biodiversity and ecosystem services in 44 marine reserves and four large-scale fisheries closures. On average, these regions had species richness 23 percent greater than non-protected areas. Tourism revenue, measured as the number of dive trips, also was increased in these areas, suggesting that not only do diverse marine fisheries serve as major global food sources, but they also provide opportunities for recreation.

The authors conclude that the loss of marine biodiversity is negatively impacting the marine ecosystem services on which we depend. Yet they believe the trend is reversible and, therefore, urge the restoration of biodiversity through careful management of fisheries, maintenance of pollution-free habitats, and creation of marine reserves.

He quoted an estimate from the World Bank that if all fisheries around the world were better managed, they would be worth $50bn a year more than their current total contribution of $274bn to global GDP. But the number of fisheries that are subject to a sustainable management programme are still a minority, and global fish stocks are falling fast. According to the United Nations Food and Agriculture Organisation, at least a third are now overexploited, depleted or recovering from depletion, and this figure is rising.

• Will Cod fishing ever return to Newfoundland?

• Should irrigation agriculture be banned over the Ogallala Aquifer in the US?

• Should American students buy cheap Chinese furniture made from SE Asian wood?

Newfoundland Cod

• Fishing methods and the fishery collapse• In 1951 factory fishing began with new super-trawlers such as the 'Fairtry'; 280 feet

long and 2,600 gross tons.[3]

• The cod catch peaked in 1968 at 810,000 tons, approximately three times more than the maximum yearly catch achieved before the super-trawlers. Approximately 8 million tons of cod were caught between 1647 and 1750, a period encompassing 25 to 40 cod generations. The factory trawlers took the same amount in 15 years. [5]

• The industry collapsed entirely in the early 1990s owing to overfishing and debatably, greed, lack of foresight and poor local administration.[6] By 1993 six cod populations had collapsed, forcing a belated moratorium on fishing.[5] Spawning biomass had decreased by at least 75% in all stocks, by 90% in three of the six stocks, and by 99% in the case of 'northern' cod, previously the largest cod fishery in the world.[5]

• After a 10 year moratorium on fishing the cod had still not returned.[7] It is likely that the local ecosystem has changed, one example being that greater numbers of capelin, which used to provide food for the cod, now eat the juvenile cod.[citation needed] The waters now appear to be dominated by crab and shrimp rather than fish.[7]

• 1977 Canada Extends boundary out 200 miles – then proceeds to decimate what’s left

• 1978 Collapse already noticable• 1988 call for cutting quotas by 50% instead compromise at 10% • 1992 – fish stocks down to 1% of 1960s levels, fishing halted• 1993 – six cod populations had collapsed including northern cod the

largest cod fishery in the world• 1996 – fishery closed – too little, too late

B. Resulting Problem:  Maledistribution

CAUSES

1. TRANSPORT:  Local transport unable to respond to acute, sudden needs (but *AIC’s air transport can, at greater cost)– political unrest always a wildcard here,

consider the problems of Tsunami Aid in Indonesia and Sri Lanka

*AIC = Advance Industrialized Country

Example

Diary of a cross-Africa Biker:   On my way to Uganda, not far from the Uganda border, I could choose out of two (dirt) roads only (a third option would lead me to a small civil war in the north of Uganda, that is no choice). A bad one and a very bad one. Because the bad one was bad enough for me I chose to take the shortcut from Mambassa to Beni. The other main dirt road of north Zaïre was actually the only road, connecting the north from Zaïre to the east of Zaïre. But because of the raining season and the enormous potholes, it was impossible for the old Fiat and Mercedes trucks to pass. There was no traffic possible for several weeks already! The road I decided to conquer was too small for the trucks and therefore not so bad, I thought. http://www.euronet.nl/users/arold/bridge.html

2. STORAGE and MARKETING

Storage and Marketing major concerns -- limits food availability

• Storage problems reflect a short time horizon– Large losses to Spoilage and Pests

Food Resources 41

2. STORAGE and MARKETING

Lack of Free Markets• Lack of adequate communication,

transportation, & incentives leads to hoarding – true "free" market could largely overcome this

issue

• landlordism vs landless ("Monopoly", not the game) -- low incentive to produce surplus

• Poor Financial Markets -- money lenders that are like parasites

Food Resources 42

 3. SITE CONSIDERATION Variation in global FOOD resource potential

• Americans as the "Opec" leader of grain?

• Can't move the mountain, then move to the mountain (immigration pull factor???)

Question

• Name other countries that are top 10 food exporters

• Second try ranking them

• If you can’t think of 10 then give as many as possible

Food Resources 43

Food Resources 44

 3. Variation in global FOOD resource potential

• Americans as the "Opec" leader of grain? – Note also Europe

Food Resources 45

4. Additional Issues

• Civil Unrest -- even if food potential high, not available

• Environmental Decline -- production can decline – REASONS

• lack of full knowledge -- leads to destructive practices

• population pressures • tragedy of the commons • "bad science"

Food Resources 46

4. Additional Issues cont.

• Government Policy & Debt – No discipline of the marketplace – What did American banks do when offered

a “free lunch”? – Punish the farmers, Bribe the industrial

workers (the shadow of Stalin and central planning)

– Sound like the Washington Consensus?

Food Resources 47

4. Additional Issues cont. (Neo Classical?)

Structure of Agriculture • Big Farmer vs Small

Farmer debate • Issue of a maximizer

versus a satisficer• Scale economies not

available to small farmers

• Cash crops not food favored by big landlords– is there no free market

for food in third world?

This demonstrates that larger farms produce a greater percentage of food for the market, but doesn’t address output per acre

Graph for a typical 3rd World Nation

Food Resources 48

4. Additional Issues cont.

• “Unfair” Agricultural Subsidies– Can the third world compete with subsidized

first world farmers??? Recall France’s position in surplus/export production.

– Example: The US has the highest priced sugar in the world??? Why?

• Why can’t we buy cheaper Mexican sugar, our NAFTA partner?

• What does this do tocandy manufacturing jobs?

D. Suggested Solutions to Food Resource Issue

Suggestions

• Give at least two suggestions

Food Resources 50

Food Resources 51

1. Increasing Local Production (More Food Answer)

a) More (or More Intensive use of) Cultivated area – make More “LAND”

• limited scope • environmental issues (marginal lands)• high development costs • China has already topped-out (see next slide)

Details on China

Source: State Land Administration, Statistical Information on the Land of China in 1995. Beijing, 1996. And equivalent reports for 1988 to 1994.

This chart demonstrates that China's cultivated land (as in any other country) is not just a given natural resource stock, but the result of various simultaneous processes of increase and decline.In 1995, for instance, China lost some 798.1 thousand hectares of cultivated land: most of it was converted to horticulture (red bar), used for reforestation (blue bar), or was lost in disasters - mainly floods and draughts (yellow bar). However, China's farmers also expanded the cultivated land by some 388.9 thousand hectares - mainly by reclamation of previously unused areas, but also by conversion of areas, which were previously used for other purposes. The net-change of these increases and declines, which amounted to some 409.1 thousand hectares, reduced the stock of cultivated land only slightly.

Food Resources 54

Details on China

Source: State Land Administration, Statistical Information on the Land of China in 1995. Beijing, 1996. And equivalent reports for 1988 to 1994.

Some general trends can be easily inferred from this chart:

(1) Approximately 70 to 75% of China's cultivated land-"losses" are not what people usually imagine - a permanent transformation of cropland into infrastructure or urban areas. Most cultivated land-losses are conversions into other types of agricultural use or losses due to disasters. Infrastructure, settlements and industries account for only some 10 to 15% of the losses.

Food Resources 55

Details on China

Source: State Land Administration, Statistical Information on the Land of China in 1995. Beijing, 1996. And equivalent reports for 1988 to 1994.

(2) There is a clear trend of growing decreases since 1990 - a year, when the decreases where actually smaller than the increases of cultivated land. This trend is not matched by an equivalent amount of reclamation, which results in a growing net-loss of cultivated Land in China.See also: Fisher, G. / Chen, Y. / Sun, L.

A record 17.3 million farmers grew GM crops in 2012, up from 16.7 million farmers in 2011.

Worldwide, 170.3 million hectares were planted with GM crops in 28 countries – an 100-fold increase since they were introduced in 1996. This is about the same size as the territories of Spain, Germany, France and the UK combined.

In the last few years, however, there has been a consistent increase in the number of hectares being planted to GM crops in the developing world. Fifty four percent (54%) of the total global GM crop area is now being grown in developing countries. A significant increase in GM crop area was reported in developing countries of Africa, Asia, and Latin America.  Experiences from these countries show that resource-poor farmers can also benefit from this technology.Food Resources 63

China Rushes to Adopt Genetically Modified Crops

NY TIMES - 10/7/00By CRAIG S. SMITH

SHAHEXIN VILLAGE, China - Until Monsanto introduced a genetically altered cotton plant here in the buckle on the Chinese Cotton Belt three years ago, farmers like Ma Yuzhuo sprayed their fields with tons of organophosphate pesticides to kill bollworms, grubs that feed on immature cotton bolls. So toxic is the compound, which is similar to the basic ingredient of nerve gas, that many people die from exposure to it each year, though the government will not disclose the number of fatalities. Bioengineered crops are not grown much in Western Europe and have raised safety concerns in the United States. But China has embraced them, growing cotton and other crops faster than any other Asian nation. Saving lives is one motivation. But saving its farm economy is the chief concern. China hopes that genetics can save farmers like Mr. Ma from devastation by helping produce lower-cost high-quality products after it joins the World Trade Organization. http://ipm.osu.edu/trans/10_071.htm
