1. The Influence of Climate and Public Health Interventions on Aedes Vectors and Dengue in Sri Lanka
Sammanfattning : Introduction: Dengue, a viral infection transmitted by Aedes mosquitos, flourishes in urban tropical environments by a complex process. Interactions among susceptible humans, dengue viruses, and Aedes mosquitoes determine dengue transmission patterns, and these interactions are modified by driving factors related to weather, the environment, and human behaviour, including mobility.

2. Inter-annual variability of rainfall in Central America : Connection with global and regional climate modulators
Sammanfattning : Central America is a region regularly affected by natural disasters, with most of them having a hydro-meteorological origin. Therefore, the understanding of annual changes of precipitation upon the region is relevant for planning and mitigation of natural disasters. LÄS MER
3. Aspects of regeneration in tropical secondary forests of Northeast Borneo affected by selective logging, El Niño-induced drought and fire
Sammanfattning : A large proportion of the world´s tropical rainforests are today secondary forests, a term encompassing forests in various degrees of degeneration. For the main traits of old-growth forests´ structures, species composition and ecosystem functions to recover, regeneration of non-pioneer tree species is essential. LÄS MER
Sammanfattning : Anthropogenic emissions of carbon dioxide (CO2) are perturbing the radiation balance of the atmosphere that ultimately determines the climate for all life on Earth. The prediction of future climate change and the explanation of observed changes are contingent on us quantitatively understanding the link between CO2 emissions and atmospheric concentrations that is provided by the biogeochemical carbon cycle.

5. Primary Production in African Drylands : Quantifying Supply and Demand Using Earth Observation and Socio-ecological Data
Sammanfattning : The human-environment connection in the mostly rural drylands of sub-Saharan Africa forms a complex, interlinked system that provides ecosystem services. This system is susceptible to climatic variability that impacts the supply of its products, and high population growth, which impacts the demand for these products. LÄS MER
