Executive Summary

Tropical dry forests (TDF), with their high agricultural and touristic potential and ideal conditions for human settlement are extremely vulnerable. This research network is developing a comprehensive knowledge basis of the human and biophysical dimensions for TDFs in the Americas.

Goals

  • Understand the role of tropical secondary forests play on interception of precipitation
    at regional level
  • Quantify CO2 and H20 emissions from tropical dry forests to support programs for payments for environmental services based on accurate carbon and water models.
  • Develop innovative links between government agencies, scientists, and communities to promote sustainable management of TDFs.

Some results

  • We have been able to quantify carbon and water fluxes from tropical dry forests in Mexico and Costa Rica under different levels of environmental stresses.
  • Our research has been able to document significant linkages between remote sensing observations, micro-meteorology and vegetation stress for tropical dry forests not previously documented.
  • Our results in Mexico and Costa Rica suggest that regeneration of tropical dry forests increases rainfall interception by close to 80% after 5-years since colonization starts. The former has significant impact on regional water management in semi-arid and arid regions of the Americas.
  • In the context of climate change, tropical dry forests are demonstrating significant levels of resilience not previously documented.
  • Tropical dry forests in Mexico and Brazil are those with significant responses to climate change. These forests are demonstrating a significant decrease in productivity in the last 30-years.

Executive summary

Tropical dry forests (TdFs), with their high agricultural and touristic potential and ideal conditions for human settlement are extremely vulnerable.This research network is developing a comprehensive knowledge basis of the human and biophysical dimensions for TdFs in the Americas.

Goals

  • Understand ecology and diversity of TdFs and the climatic and socio-economic drivers of their development and degradation
  • Document long-term trends in extent, biomass and integrity of secondary and primary TdFs
  • Develop innovative links between government agencies, scientists, and communities to promote sustainable management of TdFs

Some results

  • The first-ever map of TDFs in the Americas shows their extent and conservation/deforestation trends. In Costa Rica this mapping serves as a legal basis for conservation monitoring.
  • Dry forests are highly fragmented by touristic and agricultural development, and conservation policies need to reflect this better. TROPI-DRY proposes the creation of TDF conservation networks and payments to local communities for the environmental services they provide.
  • Phenology monitoring shows that close to the equator, the dry season is now shorter and dry forests have become more productive. Farther north and south, dry seasons last longer and dry forest growth has slowed.
  • Productivity of dry forests is increasing in Brazil and decreasing in Bolivia.
  • Data are being compiled how rural communities use natural resources in dry forests in Brazil.
  • These results are creating a solid basis for the sustainable management of dry forests across the American continent.

Outreach

April 2011: To mark Earth Week, the US National Science Foundation (NSF) has released an audio slideshow on tropical dry forests on its web site. This video, based on the results of the IAI-sponsored Tropi-Dry research project, highlights the importance of protecting biodiversity-rich tropical dry forests which have attracted much less attention than Amazon rainforests. Tropical dry forests regions are often suitable for agriculture and therefore greatly threatened by deforestation. In the Brazilian State of Minas Gerais, data provided by the IAI project researchers helped an Appeals Court to restore the forests’ protection against deforestation that had been lifted by a 2010 State Law.
