More Green vs. Green: Biodiesel and Deforestation

Substitution, opportunity costs, trade-offs --however you say it, economic decisions have consequences.  Take, for example, the case of biodiesel fuels.

From New Scientist.com:

THE drive for "green energy" in the developed world is having the perverse effect of encouraging the destruction of tropical rainforests. From the orang-utan reserves of Borneo to the Brazilian Amazon, virgin forest is being razed to grow palm oil and soybeans to fuel cars and power stations in Europe and North America. And surging prices are likely to accelerate the destruction.

[...]

Rising demand for green energy has led to a surge in the international price of palm oil, with potentially damaging consequences. "The expansion of palm oil production is one of the leading causes of rainforest destruction in south-east Asia. It is one of the most environmentally damaging commodities on the planet," says Simon Counsell, director of the UK-based Rainforest Foundation. "Once again it appears we are trying to solve our environmental problems by dumping them in developing countries, where they have devastating effects on local people."

Increasing demand for an output (biodiesel) increases the demand for intermediate inputs by suppliers (palm oil, soy beans) which increases the demand for raw materials (land).  How do we solve it?  One solution might be to tax the production of soy and palm on forested lands.  But that would put a bigger burden on local communities.  Another solution?  Create incentives for the production of alternative crops that requires less deforestation and potentially decrease the sensitivity of local incomes to fluctuations in crop prices.  Such incentives would depend on the types of crops that can be grown in each area, but a recent discussion paper out of Resources for the Future shows that such programs seem to be working for shade-grown coffee in Mexico [1].  Here's the abstract:

More than three-quarters of Mexico’s coffee is grown on small plots shaded by the existing forest. Because they preserve forest cover, shade coffee farms provide vital ecological services including harboring biodiversity and preventing soil erosion. Unfortunately, tree cover in Mexico’s shade coffee areas is increasingly being cleared to make way for subsistence agriculture, a direct result of the unprecedented decline of international coffee prices over the past decade. This paper summarizes the key findings of a three-year study of deforestation in Oaxaca, one of Mexico’s prime regions for growing shade coffee. First, we find that deforestation during the 1990s was significant. Second, the loss of tree cover can likely be slowed by promoting coffee-marketing cooperatives and “green” certification, providing coffee price supports, and specifically targeting areas populated by small, indigenous farmers for assistance. Finally, to be effective, such policies must be implemented quickly after price shocks occur.

joshua, I hope you get some of that organic shade-grown coffee after Thanksgiving turkey (cage- and antibiotic-free), served with your organic punkin pie with crust made of whole wheat flour and non-GMO soya.

Enjoy.

Yeah- I think biofuels is largely a net-negative for the environment- ultimately pretty inefficient and with all these other perverse externalities. We need substantial CAFE standard increases coupled with much more R&D for hydrogen.

"joshua, I hope you get some of that organic shade-grown coffee after Thanksgiving turkey (cage- and antibiotic-free), served with your organic punkin pie with crust made of whole wheat flour and non-GMO soya."

organic shade-grown coffee = PBR
cage- and antibiotic-free turkey = jenny-o frozen turkey loaf
organic punkin pie with crust made of whole wheat flour and non-GMO soya = no pie but box stove top dressing and instant kraft mash potatos.

i think like 80% will contain some sort of GMO.

:)

happy thanks givin you all.

Good evening. If ramping up for biodiesel has negative and mostly consequences, what new emerging technologies should I be focusing on?

I own a hybrid, independent, international, manufacturer's representative company called SPAP COMPANY LLC. My company focuses on promoting, marketing and repping highly differentiated, green, patented, energy-saving, water-saving, time-saving, renewable energy manufacturers in California of advanced technology products interested and committed to systematically exporting their products into overseas markets. I would like to open up an ongoing line of communications with this community re currently obscure California companies with commercialized or soon to be commercialized green/environmentally-focused products that might be, or will soon be, in circulation. Could you please keep my company in mind in case you, your friends or associates come across such jaw-dropping technological products made here in California?

To get a better idea about who I am and what my company does, can you please have a look at my articles, interviews and testimonials on my website link listed below. I look forward to hearing back from you.

Thank you.

Sincerely,

It is indeed true that current biodiesel feedstock are having a negative effect on the environment, but it might not be the case in future for these reasons:

1. Newly explored biodiesel feedstock such as Jatropha can grow on wastelands and arid climates and these need not hence be planted on lands that are currently growing other environmentally beneficial species
2. A good amount of research is going on in the production of biodiesel from algae. If these efforts bear fruit, once again it is quite likely that existing forests and framlands need not be touched, because the algae require much less land than traditional crops for the same output of biodiesel (their yields are about 200 times higher!), and I understand that algae can be cultivated even in deserts and such regions

The next couple of years will provide if the above two aspects can make biodiesel more environmentally sustainable
