The research of this work fits within the broad subject of greenhouse gas emissions and climate change. More specifically, this work focuses on the contribution of tropical forest soils to the atmospheric N20 and NO budgets. Nitrous oxide has a global warming potential of 310 relative to CO2 and is one of the main greenhouse gases covered by the United Nations Framework Convention on Climate Change (UNFCCC). Nitrous oxide also plays a key role in modulating the stratospheric ozone layer. Tropical forest soils are considered to be the largest natural source of N20. Additionally, they can produce considerable amounts of NO. Estimates of the contribution of tropical rainforest ecosystems, which cover u50 x ro6 ha of the global land surface, to atmospheric N20 and NO have a high uncertainty. Despite the fact that tropical forest soils are considered to be a key source of N20 and NO2 only a relatively small number of detailed studies investigating the temporal and spatial variability of the N20 and NO soil-atmosphere exchange are available, particularly for Africa. Therefore the general objective of this research was to improve N20 and NO emission predictions from tropical forest. The research has been carried out in the Nyungwe forest in Rwanda for which a large number of legacy data are available. The results of this thesis led to (i) a better understanding of the N20 and NO source strength of a central African tropical forest soil, (ii) improved NO and N2O emission estimates from a central African tropical highland forest and more insight into the importance of soil properties controlling N20 and NO emissions and (iii) a better insight in those parameters that preferentially should be monitored to allow better global simulations of N20 and NO emissions from tropical forests.

Climate Change Adaptation Strategies

The main objective of this study was to analyze local perceptions of climate variability and the different adaptation strategies of four communities in the southern Yucatán Peninsula, using the Social-Ecological System (SES) approach. Four SESs were considered: two in the coastal zone and two in the tropical forest zone. Data were collected using different qualitative methodological tools (interviews, participant observation, and focal groups) and the information collected from each site was triangulated. In all four sites, changes in climate variability were perceived as “less rain and more heat”. In the tropical forest (or Maya) zone, an ancestral indigenous weather forecasting system, known as “Xook k’íin” (or “las cabañuelas”), was recorded and the main activity affected by climate variability was found to be slash-and burn farming or the milpa. In the coastal zone, the main activities affected are fishing and tourism. In all the cases analyzed, local climate change adaptation strategies include undertaking alternative work, and changing the calendar of daily, seasonal and annual labor and seasonal migration. The population of all four SESs displayed concern and uncertainty as regards dealing with these changes and possible changes in the future.
