Los bosques son una fuente importante de energ\u00eda para los hogares rurales y urbanos en todo el mundo. Muchos consideran que la provisi\u00f3n de energ\u00eda renovable, como parte de una econom\u00eda verde, ser\u00e1 el desaf\u00edo m\u00e1s grande que la civilizaci\u00f3n deber\u00e1 confrontar en el futuro cercano. Sin embargo, la suposici\u00f3n de que las fuentes de energ\u00edas renovables, como los biocombustibles, son totalmente respetuosas del medio ambiente es con frecuencia err\u00f3nea, seg\u00fan participantes de los Di\u00e1logos de Rio+20 sobre desarrollo sostenible.<\/p>\n

\u201cLo que se puede considerar como fuente renovable no es necesariamente sostenible si la oferta de otros recursos utilizados en este proceso (por ejemplo, agua, tierras forestales) es limitada\u201d dijo Mary Menton, investigadora de CIFOR, quien coment\u00f3 sobre la energ\u00eda hidroel\u00e9ctrica y su impacto sobre los bosques en Brasil.<\/p>\n

Asimismo, el aumento en los precios del petr\u00f3leo y la creciente preocupaci\u00f3n en torno al cambio clim\u00e1tico han reforzado el compromiso de los pa\u00edses industrializados de encontrar nuevas fuentes de energ\u00eda renovable, principalmente con el objetivo de incrementar la producci\u00f3n y el uso de biocombustibles como la palma aceitera, ca\u00f1a de az\u00facar, soya y jatropha<\/em>.<\/p>\n

Sin embargo, estudios recientes sugieren que es muy probable que los biocombustibles no sean tan verdes como aparentan, ya que la creciente demanda por biocombustibles de los pa\u00edses desarrollados resulta en la destrucci\u00f3n de miles de hect\u00e1reas de bosques en todo el mundo.<\/p>\n

Al otro lado del mundo, en \u00c1frica, los combustibles de madera representan cerca del 90 por ciento del consumo de energ\u00eda primaria seg\u00fan la Organizaci\u00f3n de las Naciones Unidas para la Alimentaci\u00f3n y la Agricultura (FAO). Se requieren alrededor de siete a 10 toneladas de madera para producir una tonelada de carb\u00f3n vegetal, convirtiendo as\u00ed a la recolecci\u00f3n de le\u00f1a en un importante motor de la deforestaci\u00f3n en \u00c1frica, un continente de cerca de mil millones de habitantes que cuentan con pocas fuentes de energ\u00eda alternativa.<\/p>\n

Estos y otros temas se est\u00e1n debatiendo en el marco de los Di\u00e1logos de Rio+20, una herramienta de la sociedad civil que tiene como objetivo generar una serie de recomendaciones que ser\u00e1n presentadas a los jefes de Estado reunidos en Brasil con motivo de la Conferencia Rio+20.<\/p>\n

In the soudano-sahelian countries, we don\u2019t know much about woodlands\u2019 resilience when they are submitted to woodcutting, grazing and bushfires more or less without any control of access and use to commons. So first of all, we have to enhance our scientific knowledge on the resilience of this kind of woodland under these pressures to clarify the sustainability of a fuelwood production based on woodland exploitation. This is a key issue because, as I will try to demonstrate below, we do not have a lot of alternative to this woodland exploitation to provide the cities with fuelwood.<\/p>\n

Of course, local people have to understand and agree on the forest norms of \u201csustainable exploitation\u201d. The imposition of rules of \u201cscientific forestry\u201d to local people has demonstrated every where [has] its limits. It is the time now to elaborate these norms in common with the local stakeholders that means in terms a revolution of the \u201cforest agent\u201d posture. That is a key second issue if we want key stakeholders to follow sustainable norms of fuelwood exploitation.<\/p>\n

Concerning the fuelwood plantations, till now, it has been a complete failure. From the 1970\u2032s with the State plantations to the 1990\u2032s individual plantations, passing by the village plantations (1980\u2032s), very few of them have produced or is producing fuelwood that is sold on the market. First of all, they are very limited in area compared to woodland. And they are still too expensive compared to woodland. Maybe it can success being a credible option in the soudano-sahelian countries if the fuelwood is sold at its real price of a \u201csustainable wood\u201d. But selling the fuelwood at it real price of sustainable production will lead to consumers\u2019 riots in the cities. An option may be to subsidize these plantations, so that they can be competitive to woodland, but the problem is that most of these plantations are fast growing exotic species that are not appreciate by dwellers as fuelwood.<\/p>\n

At least, concerning the improved cooking stoves, they have been promoted since at least 40 years. That is a very good solution for very poor results in terms of development. My question is how many scientific studies have tried to understand, with an anthropologic perspective, why the soudano-sahelian women rather prefer their three-stones fire to a improved stove? Very few. Maybe a dramatic increase of the fuelwood price may push them to adopt this kind of stoves. But after 40 years, a good assessment is needed, no?<\/p>\n

\n<\/strong>Mon, April 30, 2012 at 04.52 pm<\/em><\/p>\n

Denis, Thanks for you comments. A few thoughts to add:<\/p>\n

I would agree that plantations of fast growing exotics might not be the best answer, particularly if they are not seen as good sources of fuelwood by local populations. Are there examples of fast-growing endemic species that could be used? Are there cases in your region where the remanants from sawmills, of these exotic species or others, are being used sucessfully for charcoal? In Peru, there are many examples of sawmills that convert remnants to charcoal production. How far can these types of activities go towards limiting the fuelwood footprint?<\/p>\n

The issue of the social and cultural context behind the adoption (or not) of cooking stoves is indeed crucial. Technological advances will fall short if the social, economic, and cultural barriers for uptake are too great. There are, though, some studies and reports that address these issues (see links below for some) \u2013 do we need to go further? What are the priorities for further research on uptake of improved stoves?<\/p>\n

Barnes et al. 1994. What makes peoples cook with improved biomass stoves? A comparative international review of stove programs. World Bank Technical Paper 242<\/a>.<\/p>\n

Mary, Thanks for your comments.<\/p>\n

There is no local species that can grow as fast as Eucalyptus or Acacia auriculiformis<\/em> in the soudano-sahelian context. At least, Eucalyptus camaludensis<\/em> is appreciated for house building. But even a local species like Khaya senegalensis<\/em> that is very useful and presents one of the fastest growth of the local trees cannot compete in terms of biomass production with the exotic species. As a result, even if there are some plantations of local gum trees, the very large majority of the few plantations are based on exotic species.<\/p>\n

However, a lot of local species have a good sprouting capacity, particularly the Combretaceae and some Acacia. This capacity offer to the savanna ecosystems a certain capacity of biomass regeneration. At the moment, this regeneration by sprouting is sufficient to avoid to the cities a shortage of fuelwood. But the question is: how long the savannah ecosystems around the main cities will stand this pressure from woodcutters? And can we still speak of resilient ecosystems when they lose their biodiversity to tend to almost monospecific stands regenerating only but sprouting?<\/p>\n

Otherwise, there are no sawmills in Sahel, so no remnants to make some charcoal with them. Some people try to build briquettes with the cotton stumps, but these briquettes are not very appreciated by women for cooking. There is may be something to do with the residues of the fuelwood exploitation that are usually left in the bush and useless.<\/p>\n

Thanks for your comments Denis and Mary. I went to a presentation at the recent Planet Under Pressure conference where Bob Scholes from the South African Council of Scientific Research expressed concern that Africa, being a newly emerging player in the biofuel production market, is the next continent that would suffer greatly from unsustainable food and energy production models. He also said that there was great opportunity for Africa to can learn from Indonesia\u2019s experiences with palm oil and Brazil\u2019s soybean and sugarcane industry. Does anyone have any idea what lessons in energy production that Africa could learn from these two countries?<\/p>\n

Mary Menton
\n<\/strong>Wed, May 2, 2012 at 03.40 pm<\/em><\/p>\n

Michelle, My first reaction to your question on lessons learned r.e. biofuels in Indonesia and Brazil: that extensive deforestation is likely\u2026<\/p>\n

But, perhaps more optimistically, I\u2019ve heard discussion in reference to the Brazil case of efforts towards more sustainable production (e.g. the Roundtable on Responsible Soy (http:\/\/www.responsiblesoy.org\/<\/a>) or the Better Sugarcane Initiative (www.bonsucro.org<\/a>)). I would love to hear from others as to the effectiveness of such initiatives and specific lessons learned that would be applicable to other cases.<\/p>\n

And, r.e. the question of dams (\u201cGiven increasing energy needs, is the flooding of forests for hydroelectric dams and the drilling for oil in protected areas or indigenous lands inevitable? Is it \u201cok\u201d?\u201d)<\/em> – as I look at the case of the Belo Monte dam in Brazil, it seems that given the political and economic power of the lobbies supporting these types of projects, they may be inevitable. But, is it \u201cok\u201d to flood indigenous lands? No, it is not. With these types of projects, it seems there are always groups who suffer tremendous losses that cannot possibly be compensated by resettlement packages.<\/p>\n

Biofuel production in Africa is a dangerous game as water resources are already stressed in many regions and water is best used for cereal crop production. Biofuel production uses a lot of water , causes deforestation and is unsustainable. Much of Africa has lots of sunshine for solar power and wave and wind generated power along coastal areas should be utilized.<\/p>\n

Bio fuels are not as environment friendly as some would have us believe.<\/p>\n

In rural areas in south africa , villages are being educated on utilizing cattle dung to generate Methane gas for cooking . Other areas in Africa are using solar sun cookers.<\/p>\n

Mary Menton
\n<\/strong>Wed, May 2, 2012 at 11.35 pm<\/em><\/p>\n

Deon, your point about the importance of water stress is very pertinent and brings again to the forefront the interconnections amongst the different Rio+20 themes. I also agree with you that the assumption that biofuels = environmentally friendly is often erroneous. What may be seen as a renewable source does not neccessarily mean sustainable if other resources used in the process (in this case water, forested lands) are in limited supply.<\/p>\n

deon geldenhuys
\n<\/strong>Fri, May 4, 2012 at 06.46 pm<\/em><\/p>\n

Brazil has much water , forests and land . Biofuel production will affect forest area but not have too much effect on water resources. A unnerving situation is emerging in forested areas there, regarding droughts becoming more frequent .It would be wise for Brazil to protect their valuable heritage from exploitation by other nations. Corruption amongst landowners and loop holes in the legal system must be addressed.<\/p>\n

\u2026Biofuel production is a lucrative industry but an unsustainable one. Replacing hydrocarbons with biofuel does not help the environment much and the benefits are marginal . The world can do without bio fuels as it is not a necessity . Deforestation in Borneo and indonesia is taking place at a disturbing rate to make way for palm oil plantations .Corruption and greed is driving this process as countries like India import huge volumes of palm oil from Borneo for bio fuel production etc\u2026 in Brazil will also take place to make way for Soybean production for cattle fodder destined for the chinese market. Again economics plays a role as nations import rescources for their consumption .International Laws and collective collaboration is required to prevent abuse and exploitation of the environment<\/p>\n

Central to the topic of fuel production in tropical areas is scale. There are implicit trade-offs in terms of feasibility and social development that should be considered when implementing sustainable fuel cultivations.<\/p>\n

Given current forms of trade, especially in the global context, many biofuel plantations are conceived economically attractive if they are performed at a large scale. Large-scale agriculture can reduce production costs and increase yield but they are very likely to expand into forest areas. All over the tropics there are abundant non-forest areas suitable for establishing fuel plantations that are un- or sub-utilized. Given the current economic model favoring large scale production, the feasibility for converting marginal non-forest areas into cultivations becomes difficult because most of them are already claimed or under dispute. Large investors prefer to avoid entering into land tenureship conflicts by selecting undisputed areas which are mostly covered by forests.<\/p>\n

There are examples in the literature about initiatives by communities to implement fuel plantations, particularly oil palm, in their own lands. If the right incentives are set in place, these dweller can use part of their areas that have been already converted and where production is marginal for fuel production. Incentives include technical advice and subsidies or loans for early stages of the plantations when production hasn\u2019t started. Initiatives for small-scale production often fail because smallholders do not have the resources to transform and commercialize their products. This problem might be solved by a partnership with private investors who would be in charge of transformation and commercialization. Obviously such an approach would have to guarantee a fair compensation to producers in order to be successful.<\/p>\n

\n<\/strong>Thu, May 3, 2012 at 12:25 am<\/em><\/p>\n

These are very interesting points you raise Victor and I\u2019m particularly interested in your last comment about involving the private sector. Would you or any others be able to suggest what kind of incentives we need to give business to promote more sustainable and inclusive models for biofuels and biomass supply that places lower pressure on forests and distributes economic benefits more equitably?<\/p>\n

deon geldenhuys
\n<\/strong>Fri, May 4, 2012 at 06.54 pm<\/em><\/p>\n

The only incentives that business understands is profits. One way of curbing their drive towards biofuel related deforestation would be to encourage them to diversify into other fields of industry that do not affect forests and still generate profits for them<\/p>\n

Mary Menton
\n<\/strong>Fri, May 4, 2012 at 12.50 pm<\/em><\/p>\n

Michelle and Victor,<\/p>\n

I think there are some important lessons learned from the timber sector in terms of community-company partnerships should be taken into account when developing such initiatives for biofuels. It\u2019s important to recognize that while there are numerous cases of exploitative relationships between companies and local communities, there are some examples where mutual benefit has been possible. Colleagues from IIED have written on this in the past (e.g. Mayers and Vermuelen 2002. Company community forestry partnerships \u2013 from raw deals to mutual gains<\/a>). Given the questions of scale, such partnerships may be the most efficient way for smallholders to enter the market. However, mechanisms to support transparency and equity will be essential\u2026<\/p>\n

Certification schemes, and the niche markets those bring, could help provide incentives to the private sector to improve their social and environmental responsibility. But, again, the question of scale \u2013 are the niche markets formore responsible biofuels big enough and do they pay enough to compensate the costs of participation?<\/p>\n

Dear Michelle and Mary I agree to much thing to you. But I think that in Brazil, although the hydroelectric to be cleaner of what use of diesel and radiation, could be implemented models of thermoelectrial using the residues of the forest management, and others ex. One example interesting of generation of renewable energy is of company Mil Madeiras (Precious Wood) of Itacuatiara:A company with forest certification created a power plant that uses waste wood from sustainably managed forests as a fuel, replacing electricity generated from polluting diesel generators, since 2005, to be burnt in the electric and thermal plant of vapor turbine to generate electricity for the Itacoatiara city, state of Amazonas, Brazil. A city of 80.000 inhabitants. Thus, beyond contributing with the supplying of clean energy, in a region long ago supplied 100% for generators diesel, the project contributes significantly for the reductions of methane emissions derived from the decomposition of the residues. The project consists of the application of the technology of direct combustion of residues of biomass for the simultaneous generation of electric and thermal energy and has covered about 70% the electric consumption the Itacoatiara city,AM, Brazil.<\/p>\n

Mary Menton
\n<\/strong>Fri, May 4, 2012 at 12.54 pm<\/em><\/p>\n

Edson, Thanks for sharing this example. Victor\u2019s comment brings up the issue of scale \u2013 do you think these types of initiatives could work at a larger scale? Could bigger cities create plants that take in the remnants from a host of sawmills to contribute to a % of the city\u2019s needs? What do you think?<\/p>\n

Edson Vidal
\n<\/strong>Fri, May 4, 2012 at 09.42 pm<\/em><\/p>\n

Mary, I think that is possible. In a region with a concentration of saw, some industries supplying residue would support an medium city, of 500 a thousand inhabitants, for example.<\/p>\n

Flooding of forests for hydro electric use may be a necessary step to ensure adequate and clean power supply . Coal fired power stations are bad news and trees or forests can be established in other areas to offset the loss of forest area. Hydro power stations however must be built in such a manner as to minimize the impact on the environment . They should not be seen as only energy generating structures but contribute to employment creation , fish ,agriculture , recreation , tourism , sport and complement the environment .Forest reserves should be created around dams where plants and animals can be protected and generate income from tourism.<\/p>\n

Dams must be allowed to flood rivers downstream on a regular pre determined basis to ensure the well being of fauna and flora by delivering necessary nutrients , seeds and breeding grounds for aquatic life .<\/p>\n

Dams are not as bad as some think as they reflect sunlight back into the atmosphere and have a cooling effect on the micro climate around them. They should be however built with silt build up in mind and precautions taken regarding earthquakes. The weight of water from new large dams can cause tectonic plate movement as was the case in China.<\/p>\n

Drilling of oil in protected and sensitive areas will always be a major polluting factor in these areas. Oil drilling and gas flaring has a way of destroying the micro climate and pollutes the water and surrounds for many years. Oil is a serious problem and the production and use thereof must be phased out . Fossil fuel use is primative and humanity must wean itself thereof and move on to more modern and cleaner alternatives.<\/p>\n

\n<\/strong>Sat, May 5, 2012 at 03.44 pm<\/em><\/p>\n

It is not logical to destroy forest for bio fuel production and then call bio fuel green energy.<\/p>\n

Illegal logging in the Amazon continues. Persons caught are given fines and the logs confiscated , but they return to fell more trees to pay for the fines.<\/p>\n

\u2026Brazils agri-scientists are amongst the best in the world and i am sure they are capable of managing their forests responsably.Brazil is destined to become a major role player in global food production. The reason for Brazils bio fuel program is strategic energy security.<\/p>\n

A lot of attention is given to the brazilian forests but many other areas around the globe are being affected. The U.S.A scources over 30% of it\u2019s mahogany and Birch wood from Peruvian forest. China sources much of it\u2019s wood from Russian boreal forest .<\/p>\n

Dear Deon, Thanks a lot for its valuable commentaries. But I would like to make some important commentaries on the use of forests for energy. First in Brazil currently it is possible to make cut in the Brazilian Amazon in 20% of the property, in the 80% remain is only possible to use the forest for sustainable uses: Sustainable Forest Management, Not Timber Forest Products Management, and other uses with low impacts that the cited ones above. what it was cited is the possibility to use residues wooden\/timber proceeding from Sustainable Forest Management. This activity keeps 70% of the canopy forest, is removed only 2-3 trees for one hectare (10,000 m2) and keeps several other environment services as: protection fires, protection of the water sources, protection of significant part of biodiversity, \u2026.. In fact one of the economic activities that can generate development with conservation. Other options have not had demonstrated resulted promising of low impact in biodiversity.. On the other hand an alternative that has demonstraded to be more efficient of what, for example, creation of units of conservation is the communitarian forest management, as told in the article of Community managed forests and forest protected areas: An assessment of their conservation effectiveness across the tropics (http:\/\/www.sciencedirect.com\/science\/article\/pii\/S0378112711003215<\/a>).<\/p>\n

Dear Edson<\/p>\n

Brazil is blessed with an abundance of bio diversity. It is something that should be protected and nurtured . Increasing pressure will be placed on Brazil to supply wood to other Nations . One can see what the Chinese have done to their forests and bio diversity and they are now applying pressure on Brazil and Russian forests . China and the U.S.A are the biggest importers of wood. Soya bean crops for cattle fodder destined for china is also unsustainable.<\/p>\n

In northern Borneo they have resorted to using their forests for eco tourism , protecting existing forest and establishing eco lodges , river tours , animal rehabilitation centers , indigenous people villages for tourism etc\u2026.<\/p>\n

There is no easy sustainable alternative for better forest use. Forest products should be replaced with alternative products such as Bamboo production which also generates jobs and a new sustainable industry. We could possibly see gene research producing ultra- fast growing trees that reproduce by taking cuttings . These trees would be tall and have dark green foilage . New forests could be established with these trees similar to todays pine forests.<\/p>\n

Research on crops that compliment the forest and protect the bio diversity is also an alternative to forest use.<\/p>\n

The projected climate for the Amazon is that it will eventually become savannah. The region has experienced 2 droughts within the last 5 years possibly due to the el-nino \/ la nina southern occillation .<\/p>\n
