Globalization creates forests [in some places]

Quoting from an interview between the Yale environmental website e360 and Susanna Hecht on the positive effect globalization has on the regrowth of forests in El Salvador:

With globalization and structural adjustment programs, things like corn and other basic staples were coming in at import prices that were below the cost of their production in El Salvador. That meant if you were going to sell your corn, you would be selling it at a loss. So peasant agriculture soon collapsed, allowing reforestation.

Another thing about globalization is that for niche commodities it’s quite good. Those are crops that get a premium. What it meant in the case of El Salvador is that things like cashews and coffee and artisanal products made from wood had a vigorous market compared to the crummy returns you got for corn and the milpa crops [Subsistence crops such as beans and squash.] There was a shift to higher value crops, many of them arboreal.

More than half the households receive remittances from various countries, mostly from family members in the Los Angeles area. People work at jobs here in the U.S. and send money back. If you are getting remittances, you live a lot better — it basically doubles your income. Instead of having to produce corn with low yields on, say, steep slopes, you could buy the corn for the tortillas and not have to go into these forest areas. The result was a lot of land abandonment. The land was allowed to go into successional activities or forest-based economies rather than being used for producing basically corn.

The global market is against agriculture and the farmers themselves receive so much money from relatives abroad that they can retire from farming anyway! This is happening in Europe as well as noted earlier. But a secondary forest is not the same as a primal forest and lots of people are worried that Hecht's work in the wrong hands can give a rational for the deforestation of old growth forests. Earlier we quoted David Quammen warning that the invasion of weedy species and the decline of local biodiversity creates unwanted international uniformity. Hecht responds to this in a way that with a bit of effort could still be interpreted as dismissing concerns over deforestation be positively addressing the biodiversity of second growth forests. I wonder if the second growth forests of El Salvador can be understood as novel ecosystems. 

I am always surprised how controversial this is. I think it’s partly because some conservationists don’t count secondary forest as real forest. They see forests as ahistorical and apolitical, and the forests just aren’t. It was pounded into people in Bio 101 that human interaction with forests is destructive. But there has been extensive human influence even in places like the Amazon. What my work there taught me is that these places weren’t empty, and that if you only look at the ecological side, you don’t see the social side of forests. The conservationists really don’t like this.

What helped me to see forests in degraded areas was being around people messing in the forest. So I was primed to see the El Salvador forests and not to disparage them. To me there is almost no primary forest; it’s all secondary forests. All landscapes will have to be working landscapes. If we have lots of people with forests, we should be thrilled. And we should be really thrilled when the forest comes back because we have a narrative that it doesn’t come back.

There has been a recognition that inhabited environments can have major conservation value. Even though the reforested areas are fragmented, they are quite diverse in terms of landscape. They end up actually having a rather interesting impact at regional levels — they scale up rather better than one might imagine. Even those hedgerows can provide something like 40 to 50 percent of the biodiversity that you get in a riparian system in El Salvador. And hedgerows, land demarcations, woodlots, gardens and domestic forests of various kinds all end up supporting biodiversity in ways that are kind of surprising. For instance, the bird diversity of El Salvador is about equal to that of Belize, which has a fraction of the population and far less fragmented forests.
