A road runs through the Amazon jungle, in the Brazilian state of Ceara. - HEMIS
In spite of this and other studies, the Colombian government will mix 12 per cen
In spite of its importance, little or anything has been said by the massive media about the debate conclusions, in particular the one expressed by the Chairman of the Environmental National Forum and former environment minister, Manuel Rodríguez Becerra, stating that "in Colombia there are still no conditions for agrofuels to become environmentally-friendly".
With much more time (in the Congress’s room speakers’s time was only 15 minutes) and depth, Professors Tomás León Sicard, Director of the Institute of Environmental Studies from the National University of Colombia, IDEA; Miguel Ángel Altieri, President of the Latin American Scientific Society of Agroecology, and Geraldo Deffune, Investigator and Consultant for the Agricultural Biodynamics's Brazilian Association (ABD), gave their lecture on April 25th to an auditory mainly composed for Environment and Development Magister students and Professors. Professors Deffune's and Altieri positions made journalist Judith Sarmiento, moderator of the debate, exclaimed “you leave us very anguished.”
The rise in foods prices as a consequence of the promotion of agrofuels -and government subsidies that make it more profitable to produce ethanol rather than food- is one of the aspects that has hit the entire world with more hardness and Colombia is not the exception, with an added aggravator: Colombia is comparatively one of the countries with the most expensive family food budget in the region, accounting for 30% of the whole family income, being hardly overcome by Argentina with a little more than 31%. Brazilians spent 21% in satisfying their food necessities while Mexicans 22%.
The Colombian newspaper EL TIEMPO, the most important one in the country, without mentioning the debate, pointed out in their April 28´s editorial to some important aspects on agrofuels, such as the rise in food prices that hits exactly where common people are more vulnerable, but that is not, unfortunately, the only concern on this matter. All variables involved need to be analyzed in a serious debate -said EL TIEMPO.- Such debate should include the following topics so that it can have the width and depth required:
- Full compliance of the Caution Principle
- The increase and emergence of new emissions
- The damage caused by agrofuels to the mechanical components of vehicles
- The carbon debt imposed by pruning and burning
- Displacement and murder of peasants
- The high energy deficit characteristic of agrofuels
- The validity of their denomination
- The huge amounts of water required for their production
- The implications of using Genetically Modified Organisms to produce them
- Consequences, control and mitigation policies on the use of pesticides and fertilizers
- Sustainable cultivation of energy crops, time line
- Funds for financing investigations
The inclusion of these aspects is fully justified by the following important elements:
THE PRINCIPLE OF CAUTION:
- We should be skeptical on ability of science to understand complex biosystems
- We should know how to manage risks that are uncertain at a long term
- We should consider the error possibility when estimating environmental and health
This fundamental principle has been systematically ignored in Colombia, where there was no -and there are not- enough studies allowing anticipate, as far as it is possible, the negative effects derived from the production and combustion of agrofuels, effects such as the rise in food prices that were obvious when the oxygenated gasoline program began, while effects on water, air quality, public health, flora, fauna and vehicles will require deeper analysis and studies that should have started long time ago. The clock is ticking.
In Colombia, country which have around 5 million vehicles, there were only 2 studies on 8 automobiles, which anyway show that ethanol harms some components, especially in older carburetor cars, more than a half of the colombian vehicle fleet.
Furthermore, the few studies that were carried out demonstrate the existence of unmentioned or ignored mechanical, environmental and public health risks, which makes the omission even more serious. These risks should be valued according to the people’ fundamental rights to life, health and a clean environment. In Colombia there is jurisprudence on this matter, the Contitutional Court Sentence C-293/02 mentions, among many other articles that:
“In relation to the results arising from an event (environmental damage), it is determined that it can give place to irreversible consequences if the appropriate restraining measures to stop the action that causes deterioration are not taken. If obtaining scientific certainty regarding the effect was necessary before taking any corrective measure, any determination might be inofficious and ineffective, thereby turning inoperative the preventive function of authorities”
“Human beings are the main concern regarding sustainable development. (...) For that reason, the constitutional command demands making a sustainable use of resources". (sentence C-058 of 1994). It also says that the exploitation of natural resources and the exercise of economic activities cannot go against the right to a healthy environment, regardless that the country’s economy interests lie on the economic activity to develo.”.
“Likewise, the right to the environment is fundamental for humanity's existence and it cannot be unbound from the people’s right to life and health. In fact, detrimental environmental factors cause irreparable damages to human beings and if that is so, it shall be stated that the environment is a fundamental right for humanity's existenc.”
“It is debated whether the principle of caution, which consists in that when there is danger of serious and irreversible damage, the environmental authorities should not use the lack of absolute scientific certainty as reason to postpone adopting effective measures to impede the degradation of the environment" (numeral 6 from article 1º of the Law 99 of 1993), this principle is granting limitless abilities to such environmental authorities, so that, without the needing absolute scientific certainty that the activity produces serious damages to the environment, they can adopt measures to avoid injuring the rights and interests of people affected by such decisions.”
By the other hand, the Health Secretary of Bogotá reported for 2007 an increase of more than 1700 cases of acute respiratory illness in children under the age of 5, only in Bogotá, with respect to 2006. These cared-for cases are linked, probably, to the increase in the concentration of tropospheric ozone caused by the higher volatility of gasoline when it is mixed with ethanol, which leads to a greater amount of volatile organic compounds, VOCs, in the atmosphere, which due to photochemical reactions, produce this and other pollutants hazardous to health, such as ozone, nitrogen oxides and acetaldehyde.
This increase, about 6% compared to 2006, is surely much higher taking into account that many of those affected children have no access to health care system and therefore these cases of morbidity and mortality are not recorded. Moreover, is also necessary to include other risk groups such as elders and those already suffering lung disease, throughout the country; this increase should be carefully evaluated; global warming and climate change can not be the unique and magical explanations for these phenomena, the colombian government must do everything that is feasible and humanly possible to address this situation.
NEW EMISSIONS: (The UPME, Unidad de Planeación Minero Energética, is a technical organism joined to the Colombian Ministry of Mines and Energy. Their studies and reports are used to state the laws and energy policies of the country)
UPME report, slide 47, presented on August 22 of 2007: "A widespread reduction of polluting emissions is evidenced in the entire consulted bibliography, (hydrocarbons and carbon monoxide, notice by us) except for the aldehydes and nitrogen oxides". Acetaldehyde, which is among the group of the aldehydes, is a carcinogenic compound and mutagenesis inductor while nitrogen oxides are the cause of sour rain and water reservoirs eutrophization, i.e. annihilation of all existing life forms within such reservoirs, besides severe respiratory syndromes. These are not the only noxious compounds needing to be controlled. Do we know how to manage risks that are uncertain at a long term? Is it too much to ask for the euphoria to give place to a thoughtful analysis of these and other phenomena?
The advertising machinery mounted by agrofuels promoters has focus on the decrease, very significant, we acknowledge, of non-burnt hydrocarbons, carbon monoxide and the 2 or 3 points of improvement in the octanage of Colombian gasolines. But increased production of trophospheric ozone, nitrogen oxides, aldehydes, carbonils and other toxics has been ignored thereby increasing the possibility of error when estimating the environmental and health impacts enunciated by the principle of the caution.
DAMAGE TO VEHICLES: UPME: DURABILITY. (slide 62) “The premature wear of the pieces that make up the engine due to the use of ethanol mixtures tends to be larger, presenting lubrication failures as a result of an increase in metal-metal contact between parts, due to the ethanol´s solvent action that removes the lubricant film protecting their surfaces from rubbing. Tests done in rehearsals banks show a reduction in the life time of escape valves. Also, oil tests show a larger quantity of solid material produce by the part’s wear away in comparison with the gasoline. On the other hand, the formation of solid deposits in the admission valves increases almost by 350% when a mixture of 10% ethanol is added, which forces the use of additives to reduce such increase to 50% of the gasoline’s value.”
Except for Brazil, in the rest of the world ethanol is used in proportions no larger than 10%. In fact, the use of ETBE is preferred in some European countries to improve the gasoline´s antiknock index. The main reason for this trend relies on the incompatibility of ethanol mixtures with the engine’s materials which are exclusively designed to be used with gasoline. In the United States and Australia, studies on the durability of engines working with ethanol-gasoline mixtures have been thoroughly carried out with overwhelming results: engines need to be adequate for working with mixtures whose ethanol content is above 10%.
UPME: (slide 64) “in relation to other parts of the engine, corrosion problems are seen in the carburetor, fuel supply system, the fuel hoses, the filter and the fuel tank. The largest problem occurs when the particles that are removed in the corrosive process, travel via the fuel, causing stings or pricks. To surmount this phenomenon, Zinc, tin and coal coating have been implemented in order to protect systems that were originally designed to be used with gasoline and that are to be used mixtures of ethanol blends between 14% and 20%.” ¿But what happens with blends between 10% and 14%?
There are no vehicles in Colombia that can withstand these mixtures, and even if the new cars are made with the required specifications, nothing is said about the possible mechanical damage to nearly 5 million vehicles currently circulating in the country, which demonstrates improvisation and irresponsibility about the topic.
Slide 130 entitled FACED CHALLENGES, the UPME says that the government should: “prepare the entrance of superior percentage mixtures without harming the consumer (20% from 5 to 10 years)”. The cost of adapting vehicles to be used with mixtures containing more than 10% of ethanol is estimated between US$400 and US$500. “Without harming the consumer” means that these costs will be assumed by the government? ¿or that nobody will get sick by some unknown (for him) emissions? Would not it be better, before making cheerful accounts and embark the country in a bigger adventure, to evaluate all implications derived from the use of agrofuels?
The Germans, well-known worldwide as expert automobiles manufacturers decided to postpone the ethanol’s entrance into their country until 2009 and reduce the amount of ethanol included in the mix from 10 to 7%. The German environment Minister, Sigmar Gabriel, justified the decision by stating that a fuel of those characteristics would damage the engines of millions of old cars whose drivers earn little money so as to buy more expensive cars. It should be noted that in Europe, the term “old cars” refers to those cars with more than 5 years of use. In Colombia most vehicles, around 60 per cent, have more than 10 years of use and it is not strange to find vehicles with 20, 30 and more years of use.
When ethanol conversion first started, it was greeted into Europe as an indirect way of reducing carbon dioxide emissions. Today the question lies on whether producing ethanol does not in fact causes more damage to the environment than the fuel it is meant to replace, admitted the Minister, who spoke about the damages caused by the use of fertilizers and the deforestation implemented to clear out areas for growing biocrops, says the report.
THE CARBON DEBT: The former minister Manuel Rodríguez Becerra said during his intervention that agrofuels have a negative balance for Colombia. “In several regions of the world, the development of this industry has implicated the destruction of wide forest areas, such as in Indonesia, and has contributed largely to the production of green-house effect gases, without mentioning the problems such as soils degradation, destruction of biodiversity, water contamination among other.”. He is right, Malaysia is one of the world’s largest contributors of carbon dioxide, accounting for 8% of the world’s total production due, mainly, to cultivation of palm oil. The pattern of exploitation followed in Malaysia is clearly inconvenient for Colombia at medium and long term.
DISPLACEMENT AND MURDER OF PEASANTS: The requirement -it wasn´t an expression of altruism from the Colombian palm growers- on an stamp of environmental quality that the European Union imposed to the Colombian exports of palm oil confirms the existence of dark aspects that should be object of opportune, systematic and wide analysis.
A report written by Fidel Mingorance, entitled “The flow of the palm oil Colombia-Belgium-Europe,” that was published for the first time in November of 2006, carried out by request of the Belgian Government, gives full details of three important elements: the plantations, the paramilitarism and the mandatory displacement as consequence of the robbery of lands. It is not, like the President of Asocaña, (sugar cane sowers association) suggested during his intervention in the Colombian Congress, of “leftist” positions, but of making the things well, in benefit of the country and its people. The hunger, the displacement and the misery lack political color for who suffers them.
ENERGY DEFICIT: The ethanol provides 33% less energy than the gasoline. Tadeus Patzek, professor of Civil and Environmental Engineering of Berkeley, demonstrates that until 70% more energy is invested in producing a gallon of ethanol that the one that is possible to recover of the same one. In Colombia agrofuels don't pay taxes of any class, its consumption is obligatory and they are strongly subsidized, otherwise their production would be unviable.
Gigantic plantations would be needed, Patzek says, “to replace 10% of the fossil energy used globally every year during 40-80 years. Near 500 million hectares, (a little more than half of the surface of the United states) These plantations would be implemented in the tropics, in good climates, with abundant provision of water, good lands and easy access.” This is the true reason of the interest of Europe and the United states in Latin America, like biomass and agrofuels supplier.
THE DENOMINATION: Central topic of the debate that proposes EL TIEMPO should be their denomination, that should not be limited to discuss if they are agro or biofuels. Under any of these denominations, is a fallacy to name "biogas" to the mixture of more than 250 chemical compounds with 10% of a fuel of agricultural origin, the ethanol. The use of the prefix "bio" is an advertising trick, it is the commercialization of the ecology, of the green concept, without a demonstrated real interest from the producers.
In the United States, at the beginning of last century, they decided to add tetraetil-lead to the gasoline and they called it "etilgasoline," name that masked for long time the noxious effects of the lead but it didn't avoid that millions of people in the entire world, children especially, developed neurological, renal, psychological and other affections while many millions died prematurely.
WATER WASTE: Tatiana Roa, the Censat Agua Viva Chairwoman, Colombian environmental organization who protects water, alerted industrial and other people that works in the topic about to integrate these cultivations with the necessities of the populations and take care of the water and the production of foods. Their concern is more than reasonable, 800 or even more gallons of water are required to produce one of ethanol while the pesticides and fertilizers used contaminate the phreatic level water that later will go to the rivers. It is still fresh in the memory of the country the news about the need of import “bagre” (kind of fish) from the Vietnam Mekong, shortage due mainly to the contamination of the rivers that transforms them into sewers replete of chemical and organic waste, not capable for the life. Waters that are also used for irrigation in many places of the country and human consumption and of animals.
THE ORGANISMS GENETICALLY MODIFIED (OGM): Professor Geraldo Deffune considers that Latin America could benefit economic and socially for the agroenergy development and its production if the principle of the caution was applied; however, said, the monocultives and the patents of seeds generate technological and energy dependence, contamination, rural exodus due to the concentration of the best lands in hands of powerful industrial groups, and economic dominance. 80% of the terrestrial biomass is make up for trees, for that reason to fell trees harms an irreparable to the country, he said.
The genetically modified organisms are a good opportunity to solve some problems but they also outline a series of queries related with the contamination of other cultivations, the rupture of the biological cycle and the health of who consummate them as foods. It should be carefully evaluated, matter that is not easy due to the enormous strategic and economic interests involved. Examples are plentiful:
The Hungarian scientist Arpada Pusztai found results very worrying related with rats fed with transgenic potato, for what he requested more time and money to enlarge his study. Not only he didn't receive the money but rather after granting an interview to a television media about the topic, he was dismissed from Rowet Institute, in Aberdeen, Scotland, investigation center in which he worked during 37 years. This fact is known better as the Pusztai affair.
March 11, 2007, full color and in the Colombian main media, under the suggestive title of More Corn, More Country, Monsanto “shares with all of you that we have received approval of the National Government through the Agricultural Colombian Institute, (ICA) following the recommendation of the National Technical Committee of Biosafety, to begin controlled sows for the technology of corn YielGard". This is not a distant problem, the OGM era already began in Colombia.
FERTILIZERS AND PESTICIDES: Another stone inside the shoe: The Atrazine, professor Miguel Angel Altieri said, is causing gonadal changes and hermaphroditism in amphibians exposed in very small dose, of 1 ppm (parts per million). The Atrazine, potent herbicide, can affect pregnant women that enter in contact with them in the farmers in which has been used, slowing the normal growth of their babies. In exposed animals at high levels, birth defects have been observed, damage of the liver, the kidney and the heart. Glifosato and other pesticides are every time more questioned by its harmful effects for people, animals, water and plants.
RENEWABLE IS NOT THE SAME THING THAT SUSTAINABLE: Although they are fuels obtained from renewable sources, it doesn't mean it that these cultivations are sustainable. The demands every time bigger of agro-fuels imply to use more and more new lands to produce them while the exhaustion of the farmlands after some years of use goes into a spiral that will make collapse in some moment the whole agricultural structure if not is determined with enough anticipation how many and which farmlands can be used for this purpose.
One of the most perverse effects in this system consists of the appropriation of the best farmlands by the big economic, national and international groups, expelling from their farmlands to the peasants, who later will augment the cords of misery in the cities, due to their inability to compete industrially. Always they are the losers. Agrofuels are not an energetic nor environmental solution and they should be treated as a partial and temporary solution that should not amuse in the search of really clean and sustainable energy sources, is necessary to finance investigations and to form competent professionals, starting right now.
The recent case of Carimagua, an 18.000 hectares farmland located in the Colombian east plains that later shrank at 17.000, was given to a group of displaced peasants in 2007 but later was offered to palm oil growers. The arguments fenced by the Agriculture Minister to change the addressees were “the acidity of the soil, the inability of those displaced to invest in the improvement of the lands and the location, far from the cities.”
FINANCING OF INVESTIGATIONS: The GMO corn also caused severe damages to the mice used for tests in very short periods of time, Professor Deffune said, without these results had been disclosed.
The reason is, surely, that behind these investigations exists a great investment, generally of the same companies that produce the seeds and the technology. The alliances, acquisitions and coalitions of the last years between the makers of seeds and pesticides are a clear signal. Monsanto, Novartis, DuPont, Aventis and AstraZeneca control almost the 100% of the transgenic seeds market and, simultaneously, two thirds of the pesticides market that only in the United States reports today annual incomes for 34 thousand million dollars.
It is, the biologist and journalist Zaira María Amaya Lesmes says, “as if the owner of a hospital bought the mortuary and the cemetery of the side: he wins if the patient lives, but doesn't stop to win if he dies.”
Recently the British Petroleum, BP, donated to the Californian University of Berkeley, the Lawrence Livermore Laboratories and the University of Illinois 500 million dollars devoted to develop new energy sources: basically biotechnology to develop plantations that generate agrofuels.
The executive director and president Robert A. Malone said that the BP was “joining to some of the best world talents in sciences and engineering to respond to the demand for energy with no carbon emissions that we will be working to improve and to expand the production of clean, renewable energy, through the development of better plantations.” In spite of its magnitude, this is a relatively modest investment considering that they will appropriate of the knowledge and the academic know-how that the government support took decades in building.
The agrofuels boom arises starting from the energy necessities and reduction of consumption of petroleum in the European countries and in the United states mainly, that have found in the Latin American countries the ideal conditions to produce them, a pantry to which one can go so that they can continue maintaining its overwhelming consumption rhythm, what could be not too bad for Latin America if we strictly obey the principle of caution.
The agrofuels are not bad for themselves but for the way and the methods used to produce and sell them. They constitute a good opportunity for the Colombian and Latinamerican agriculture, if and only if, we make the things well, with more technical, social and human approaches that commercial ones. To keep for us the damages that agrofuels cause while other, without to care who they are, take advantage of their advantages, would be a suicide, a self-damage that we would take decades in recovering, if we are able to make it.
WHEN ECONOMIC INTERESTS HAVE PRECEDENCE OVER COMMON SENSE
Since April 2006 we sued the Colombian government, demanding for more research be carried out on the production and combustion of agrofuels to better understand, anticipate and mitigate as far as possible, the mechanical, environmental, social, economic and public health effects that these agrofuels have and will have.
The phenomena associated with agrofuels are not well understood and even worse, ignored or underestimated, which have lead to recent and strong pronouncements from scientists, organizations such as FAO, World Bank, UN, EU and a significant number of environmental and human rights organizations throughout the world.
Despite a large number of international studies demonstrating risks and dangers associated to the use of agrofuels, added to those that appear every day worldwide, Judge Matilde Lemos Sanmartin, ex-fifth Administrative Judge of Bogotá, said that “the evidence presented is insufficient,” and thus refused the request of more and deep studies, ignoring the precautionary principle and the available legal mechanisms to obtain these studies, mandatory when the discussion is so important for the citizenry and the country, importance that can be applied also to many other Latin American countries.
Curiously, our demand was the last judgement signed by Lemos Sanmartin before being promoted to Judge of the Administrative Tribunal in the Arauca Department. We could not prove that her judgement has been pressed, bought or manipulated, but this coincidence leaves us a bitter taste. The judgement has been appealed, we hope that will be accepted for review by a different and interested court.
Anyway, we will not relent in our efforts to demand that ethanol and oil palm production be carried out with human and social sense, and not only commercial objectives like are happening right now in Colombia.
Agrofuels should be seen as a temporary and partial solution, not as a total remedy. We do not consider acceptable nor secure the omission of serious and conclusive studies in order to protect economic interests that hardly benefit persons other than the owners of this profitable business; we will appeal to all possible instances in Colombia and abroad to force that precautionary principle be applied in order to protect ourselves and future generations of irreparable damages which could result prohibitively expensive in terms of environment and public health.
