Biodiversity and Agricultural Biotechnology at the Crossroads.

Costa Rica, like many other tropical countries, is at the crossroads of agricultural biotechnology and biodiversity conservation. On the one hand, agricultural expansion has resulted in the last decades in poor natural resource management, using a model based on plentiful use of agrochemicals to maximize production, with potential adverse effects on biodiversity.  Imports of agrochemicals increased in the last years, and yet there was no significant increase in crop yields per hectare in the last decade. On the other hand, Costa Rica is one of the twenty countries with the greatest biodiversity and has enjoyed a long history of conservation of its natural resources. Its National System of Conservation Areas comprises today over 25% of the national territory. Conservation Areas are contributing substantially to the economy, as they are the main attraction for tourism and one of first sources of income.

The challenge for Costa Rica is to decide whether to continue with unsustainable agricultural practices, or to explore other alternatives, such as the introduction of genetically modified (GM) crops and other biotechnologies, that might offer opportunities to reduce the use of agrochemicals and increase yields. However, as with any other new technology, a careful consideration of potential environmental effects, including gene flow from GM plants to natural variants needs to be considered. Having a quarter of its territory reserved for biodiversity protection, and realizing that only 15 percent of the soils are adequate for agriculture, Costa Rica needs to find ways to take advantage of both biotechnology and its own biodiversity. Innovative strategies to link conservation and biotechnology should make a wise use of its biological/genetic resources, and lead the way to increased agricultural production.
