Indigenous lands protect 23% of the Brazilian Amazon, covering more than 100 million hectares, and area the size of Colombia. Maintaining the integrity of these lands is crucial to contain deforestation, maintain the stability of the regional climate, mitigate global climate change, and protect indigenous rights. Indigenous land rights in the Amazon, however, are at important risk. Around 60% of mining concessions in Brazil are in the Amazon region. Indigenous lands have frequently reported illegal mining.
Contribution of transpiration to forest ambient vapour based on isotopic measurements
Contribution of transpiration to forest ambient vapour based on isotopic measurements
Using a simple isotope mixing model, we evaluated the relative proportion of water vapour generated by plant transpiration and by soil evaporation at two sites in the Amazon basin. Sampling was carried out at two different soil covers (forest and pasture), in a...
