In the news January 16th - 20th: Saving the African lion, the implications of landslides, a jellyfish invasion, and much more.


1. New Law Forces Manufacturers to Pick up Recycling Costs
A new recycling law in Maine makes that state the first in the nation to require manufacturers to assume the recycling costs of the TVs and computer monitors they make. Under the law, manufacturers are billed based on the amount of e-waste the state's consolidators extract from the equipment. Lead, mercury, and other toxins are commonly found in monitors and televisions, and the Maine law aims to keep them out of landfills and incinerators.


2. Twelve States Oppose Bush Plan to Cut Companies' Burden on Reporting Pollution
Changes to pollution-reporting rules proposed by the Bush administration in September have received with less-than-open arms by a dozen states. New York Attorney General Eliot Spitzer summarized the objections of those states: "This EPA move appears to be yet another poorly considered notion to appease a few polluting constituents at the expense of a valuable program." Among other things, the administration's proposal would raise the threshold at which companies would be required to report releases of toxic pollutants.


3. Japan Grapples with Invasion of Giant Jellyfish
They might not pack the same emotional impact as "Jaws," but another sea creature is plaguing the waters off Japan. Huge jellyfish have been wreaking havoc with the fishing industry, ruining nets and wasting fishermen's time. The mildly toxic jellyfish are only minimally harmful to humans; it's their economic impact that has fishermen at their wits' end. "If your nets are full of jellyfish, of course there is no space for fish," said Toyama fisheries federation representative Noriyuki Kani.


4. Oil-Stung Caribbean Looks at Energy Alternatives
In a part of the world where the sun has long attracted tourist dollars, it may soon have an even greater impact on the economy. Some Caribbean countries are looking to solar energy and other alternative energy sources as the fear of escalating oil prices continues to grow. According to Trevor Boopsingh of Trinidad-based Kenesjay Systems, "The impact of high prices creates real hardship and I think the opportunity arises to get some real focus ... on diversification."

5. USDA Investigators Slam Agency for Poor Oversight of Biotech Crops
The USDA's inspector general has released a report that finds the department has fallen down on the job of monitoring vast expanses of experimental biotechnology crops. Among the concerns raised by the revelation is the fear that biotech crops left unchecked could cross-pollinate with other crops, possibly compromising the integrity of organic produce. "The system has been set up practically as a self-reporting system," according to Center for Science in the Public Interest's Greg Jaffe. "It's a 'don't look, don't find' policy."


6. Judge Rules Alaskan Wolf-Killing Program Illegal
No more may Alaska wildlife officials shoot wolves from the air in the name of boosting game populations. The wolf-killing program, which has generated much controversy since its inception in 2003, finally met its own demise at the hands of a judge on Tuesday. Retired federal biologist Vic Van Ballenberghe applauded the ruling. "It reaffirms what some of us have been saying, and that is that the programs are poorly grounded," he said.


7. Landslides Could Worsen with Global Warming
Here's another evil of global warming: Apparently it can cause the earth to fall out from under your feet. With landslides killing up to 1,000 people a year for the past two decades, experts point to rising temperatures as a contributing factor, bringing ever more frequent heavy, soil-soaking rains. A report released this week points out that the landslide danger extends to a number of the world's important cultural sites, including Egypt's Valley of the Kings and China's Huaqing Palace.


8. Conservationists Agree on Steps to Save African Lion
For the African lion, it's not easy being king. In some areas, the species is teetering on the edge of extinction. According to a statement released by the World Conservation Union, "...the reduction in the lion's wild prey base, human-lion conflicts and habitat degradation are the major reasons for declining lion populations and need to be addressed." Initial steps toward saving the regal animals were hammered out this week at a meeting of various interested constituents.


9. EU Head Office Says Enforcement of Fishing Rules to Protect Stocks is Seriously Flawed
An increasing rate of breaches in EU fishing rules by many countries -- most notably Ireland and Spain -- endanger the survival of such species as cod, according to the EU's annual "fisheries scoreboard." Shoddy enforcement is identified as a major culprit. According to EU Fisheries Commissioner Joe Borg, "Failure to enforce fisheries measures works against the interests of fishermen as it leads to overfishing, depleted fish stocks, smaller catches and shrinking incomes."


10. Animals Healthy at Jackson's Ranch, USDA Says
A USDA inspection at Michael Jackson's Neverland Valley Ranch in California found that the animals kept in his private zoo are just fine. The surprise visit by the USDA, initiated by concerns raised by People for the Ethical Treatment of Animals (PETA) over the animals' welfare, resulted in the conclusion that "There are no violations of the Animal Welfare Act," according to Darby Holladay of the USDA.

The Power to Change... By Choosing the Coffee We Drink
By Gordon Feller, Urban Age Institute


Like petroleum, coffee is a widely traded global commodity, mostly consumed in developed countries and produced in developing countries. But while petroleum producers have recently seen international oil prices rise steeply, coffee growers have experienced the opposite. Structural changes in the coffee market during the 1990s—including the collapse of the international coffee cartel and greatly expanded production in Vietnam and Brazil—drove bulk coffee prices to a 100-year low in 2001. The ongoing “coffee crisis” has caused widely reported economic hardship in Latin America where small- scale farms predominate. Less well known is that the crisis has damaged forest ecosystems in this region. Why?


Unlike “sun” coffee grown elsewhere, a sizable percentage of Latin American coffee is grown under natural or managed tree cover, often in coastal areas that are quite rich ecologically but that face mounting population pressure. Because it preserves tree cover in these areas, shade coffee provides important environmental services including harboring biodiversity, sequestering carbon, and preventing soil erosion.


Unfortunately, in Mexico, as in other Latin American countries, the coffee crisis has jeopardized these environmental benefits. Faced with low prices, shade coffee growers have been forced to find alternative sources of income. Some have migrated to cities to find employment, abandoning their farms and leaving them vulnerable to encroachment by conventional farmers, ranchers, and loggers. Others continue to grow coffee but have cleared forest on and around their farms to sell the timber and plant conventional crops. What ever the specific cause, ecological damage from deforestation in shade coffee regions has been significant, and some of it— notably species loss and soil erosion—may be irreversible or nearly so.


Policymakers are increasingly concerned about the environmental fallout of the coffee crisis. A number of international organizations have established high-profile programs to stem the loss of Mexican shade grown coffee. For example, Conservation International, Starbucks, and the World Bank have joined forces to promote shade coffee near the El Triunfo Biosphere Reserve in the state of Chiapas. In addition, the Commission for Environmental Cooperation, a tri-national organization set up under the North American Free Trade Agreement, has established a program to study and promote Mexican shade coffee.


Despite international efforts, deforestation in Mexico’s shade coffee growing areas remains poorly understood. To help fill this gap, a research team undertook a three-year study funded by the Tinker Foundation and the Commission for Environmental Cooperation. The team was made up of a group from the US-based non-profit Resources for the Future and the Universidad del Mar, a public university in Oaxaca, Mexico. They focused on a 600,000-hectare subset of the Sierra Sur y Costa region in the state of Oaxaca where shade farms produce about one- fifth of Mexico’s coffee. The team addressed the following specific questions:


Prior to the coffee crisis, what factors explained spatial patterns of deforestation in “shade coffee forests” (that is, forests in the altitude range where coffee grows) -- and how did these patterns differ from those in nearby natural forests?


How much deforestation occurred in shade coffee forests after the onset of the coffee crisis between 1993 and 2001 and what factors explain spatial patterns of this deforestation? ∫ What drove growers to abandon shade coffee plantations, and how could abandonment be prevented?


To answer these questions, the research team assembled a geographic information system (GIS) with detailed data on: land cover (obtained from 1993 aerial photographs); institutional features (such as the percentage of coffee growers who belonged to cooperatives); geophysical attributes (for example, altitude, soil type, and distances to urban centers); socioeconomic characteristics (such as population and poverty levels); and the size of the farms. The team used statistical techniques to determine which of these characteristics were associated with tree clearing. They found that, in general, characteristics that tended to lower the profitability of shade coffee compared to the profitability of activities that require direct sunlight (like growing corn) promoted tree clearing. For example, they found that areas farther from cities were more likely to have undergone deforestation. Coffee farms far from cities are less profitable than those close to them because growers incur significant costs to transport goods over the areas’ abysmal local roads.


The team also found that clearing tended to occur in areas where few coffee growers were organized into marketing cooperatives, where coffee farms were small, where indigenous peoples were prevalent, and at lower altitudes. Coffee farms in areas that are underserved by marketing cooperatives are relatively unprofitable because growers receive lower prices for their beans and pay higher prices for farm inputs. Small farms tend to earn less because growers lack the bargaining power needed to negotiate advantageous prices with local buyers. Farms in indigenous areas often receive lower returns because growers do not have equal access to state-provided agricultural services. Finally, farms at low altitudes earn less because they produce lower-quality coffee.


Having analyzed spatial patterns of clearing in shade coffee forests, the team examined those in nearby natural forests and compared the results. The team determined that, all other things being equal, clearing was less likely to occur in the shade coffee forests than in natural forests. In addition, the team found that in natural forests, clearing tended to occur close to cities because conventional farms want to have easy access to urban markets.


To address this question, the team created new land cover data using satellite images of their study area from 1993 and 2001 and used this new data, along with the GIS described above, to analyze changes in forest cover during this time. The team found that roughly 8,000 hectares of tree cover, representing three percent of the shade coffee forest in the study area, were lost during this period. As for spatial patterns of clearing, they found that during the coffee crisis, clearing in shade coffee forests tended to occur in areas where economically vulnerable small farms were prevalent. Clearing also occurred near cities, the opposite of the pattern that predated the crisis. The reason for this change may have been that when coffee prices plummeted, coffee growers near cities were more likely to clear land to raise conventional crops because markets were close by. Also, such growers may have been more likely to abandon their farms because the cost of migrating to a city was relatively low.


By conducting interviews with growers and collecting agronomic data, the team learned that a coffee grower’s decision to abandon his or her farm is typically the last stage of a long downturn touched off by a decline in coffee prices. When prices decline, many growers migrate to cities after harvest season to supplement their incomes. In doing so, they forgo important farm maintenance, such as pruning coffee plants after harvest. When this occurs, the yields from coffee plants decline significantly in the next season. Lower yields imply growers will again need to find off-farm work and will again forgo maintenance. As a result, bad prices in one year can set in motion a downward spiral of falling incomes and yields. Eventually, coffee yields drop so low that growers are forced to clear trees to grow subsistence crops and, ultimately, to abandon their plantations.


The team built a numerical simulation model to analyze the effect of a variety of popular policies on a grower’s abandonment decision. These include: improving access to credit, establishing a price floor for coffee, paying the grower for the environmental services her coffee provides, and certifying her coffee as environmentally friendly so that it commands a price premium (a strategy that has shown considerable promise elsewhere but that is rarely used in this study area). The study found that although all of these policies have the potential to prevent abandonment, whether they actually do depends on putting them in place quickly after a price shock. Once a downward spiral has begun, they will have little impact.


The coffee crisis of the past decade has weakened the ability of Mexican shade coffee to serve as a bulwark against deforestation, according to the research. But there are steps that policymakers can take to reverse this trend. The statistical analysis of land cover data indicates promoting coffee marketing cooperatives can help stem deforestation in shade coffee areas. It also suggests that road building and other investments that cut travel time will likely have countervailing impacts on deforestation. When coffee prices are strong, transportation investments promote shade coffee and, therefore, forest cover. However, when coffee prices decline, such investments may encourage coffee growers to abandon their land or to clear trees to plant conventional crops. In addition, research shows that heavily indigenous shade coffee areas and those with many small farms are experiencing relatively rapid deforestation and therefore may be good targets for assistance. Finally, numerical simulations suggest that often-used interventions like price supports and coffee certification need to be put in place expeditiously to make a difference.


This same team is pursuing several other new research projects that build on the Oaxaca study. One analyzes the effectiveness of a recent Mexican coffee price-support program in stemming the loss of shade coffee. A second project uses the empirical methods which they developed in their Oaxaca work to analyze the impact of the coffee crisis on deforestation in El Salvador, a densely populated country that has already lost more than 95 percent of its original forest and where virtually all of the remaining tree cover is associated with shade coffee.
