Article
Dengue virus (DENV) is an endemic disease in the hot and humid low-lands of Colombia. We characterize the association of monthly series of dengue cases with indices of El Niño/Southern Oscillation (ENSO) at the tropical Pacific and local climatic variables in Colombia during the period 2007-2017 at different temporal and spatial scales. For estimat...
Article
Poorer countries often face a severe trade-off: the need to improve socio-economic conditions is hard to balance with the maintenance of key ecological processes. As a case study, we select Colombia, a Latin American country with almost 10% of its inhabitants living in extreme poverty. We elaborate a water-food-labour (WFL) nexus grounded on a sub-...

Plant-microbe symbiosis is pervasive in the Earth’s ecosystems and dates back to the early land colonisation by plants. Mutualistic partnership with rhizobia bacteria and mycorrhizal fungi promotes plant nutrition, growth and diversity, impacting important ecosystem functions. However, how the global behaviour and dynamical properties of an ecosyst...
Article
Atmospheric CO2 concentrations strongly influence the exchange of energy, water and carbon between the atmosphere and the terrestrial biosphere. The CO2 available to plants can be highly variable given the stochastic nature of the phenomena involved in its dynamics. However, most terrestrial ecosystem models consider CO2 concentration as a quasi-de...
Article
Full-text available
The response of terrestrial ecosystems to increased atmospheric CO 2 concentrations is controversial and not yet fully understood, with previous large‐scale forest manipulation experiments exhibiting contrasting responses. Although there is consensus that increased CO 2 has a relevant effect on instantaneous processes such as photosynthesis and tra...
Article
Full-text available
Boreal forests fix substantial amounts of atmospheric carbon (C). However, the timescales at which this C is cycled through the ecosystem are not yet well understood. To elucidate the temporal dynamics between photosynthesis, allocation and respiration, we assessed the radiocarbon (C14 ${}^{14}\mathrm{C}$) disequilibrium (D) between different C poo...
Article
Full-text available
A clear definition of carbon sequestration in soils is necessary to quantify soil's role in climate change mitigation accurately. Don et al. (2023) proposed defining carbon sequestration as "[the] Process of transferring carbon from the atmosphere into the soil through plants or other organisms, which is retained as soil organic carbon resulting in...

Full-text available
Background The introduction of Wolbachia (wMel strain) into Aedes aegypti mosquitoes reduces their capacity to transmit dengue and other arboviruses. Randomised and non-randomised studies in multiple countries have shown significant reductions in dengue incidence following field releases of wMel-infected Ae. aegypti. We report the public health out...

We present an extension of the stochastic ecohydrological model for soil moisture dynamics at a point of RodríguezIturbe et al. (1999) and Laio et al. (2001). In the original model, evapotranspiration is a function of soil moisture and vegetation parameters, which makes the model suitable for water–limited environments. Based on the Leuning’s stoma...
Article
Full-text available
Solar radiation has a crucial role in photosynthesis, evapotranspiration and other biogeochemical processes. The amount of solar radiation reaching the Earth's surface is a function of astronomical geometry and atmospheric optics. While the first is deterministic, the latter has a random behaviour caused by highly variable atmospheric components su...

Background: Dengue, chikungunya and Zika are viral infections transmitted by Aedes aegypti mosquitoes, and present major public health challenges in tropical regions. Traditional vector control methods have been ineffective at halting disease transmission. The World Mosquito Program has developed a novel approach to arbovirus control using Ae. aegy...

Abstract. In this paper, we present a methodology to analyze the stochastic component of daily solar radiation at the earth's surface in the photosynthetically active spectral band. Extraterrestrial solar spectral irradiance from the SOLID project and in situ observed PAR from the FLUXNET data set are used to calculate daily time series of the clea...
Thesis
Full-text available
I investigate the daily dynamics of the soil-water-climate system in water- and energy-limited environments. I analyze the stochastic component of radiation at the Earth’s surface in the photosynthetically active spectral band in 28 sites located around the world and propose a clear-sky based methodology to model it. In order to study the effect of...
Article
Full-text available
Due to the complexity and uncertainty involved in mass movements, it is not possible to predict their occurrence with accuracy. This uncertainty is due to the space-time variability of physical soil parameters and processes, which determine the boundary conditions of the problem. In this study, we analyzed the influence of spatial variability of th...
Article
Rainfall-triggered landslides are the result of the complex water-related processes occurring in the atmosphere-soil-vegetation system. In this paper, we present a methodology to assess long-term slope stability from rainfall, soil, and vegetation parameters. Our approach couples the stochastic ecohydrological model developed by Rodríguez-Iturbe et...
Conference Paper
Landslides are among the most frequent disasters and cause significant economic and human losses in the world. Colombia, located in the northwestern corner of South America, has high rainfall and steep slopes with deep weathering soil profiles, providing favorable conditions to landslides occurrence. Fractal theory is a tool used to describe scale-...
Article
Full-text available
Precipitation is one of the main landslides triggering factors because the amount of infiltrated water into the soil causes changes in pore pressure due to the decrease in suction or the rising water table level. In this paper we estimated the return period of landslides from a rainfall stochastic behavior. We obtained the pdf of water infiltrated...
Article
Full-text available
Landslides triggered by rainfall are one of the most common causes of disaster in tropical regions, characterized by having deep weathering soil profiles, steep slopes and high-intensity storms. The increasing number of landslides during wet season evidences the close relationship between hydro-climatic conditions as a triggering factor for the occ...

Article
Full-text available
Many infiltration models have been developed to predict infiltration rate as a function of time and physical or empirical parameters, for a different type of soils. Each of these models is suitable to certain conditions. The parameters feed these models have uncertainties. These uncertainties become important depending on the sensitivity of them to...

Thesis
Full-text available
The study of the problem of rainfall-triggered landslides is an issue of interest for both geotechnical engineering and hydrology. However, the concepts developed by these disciplines have not been linked properly, considering major simplifications. Moreover, the occurrence of landslides involves significant uncertainty, which in part is due to the...

We present a model for the estimation of the long-term probability occurrence of landslides based on the derived distributions technique. The model estimates the probability density function (pdf) of the Factor of Safety (FOS) from the statistical behavior of the rainfall process and some soil and slope parameters. The stochastic character of the r...
