Floods are one of the most frequent, dangerous natural disasters globally. During the period from 1990 to 2020, more than 50% of the world's recorded disasters were related to floods. This problem stems largely from the inadequate planning and economic circumstances of human settlements in flood-prone plains. Geospatial modelling can be a powerful...

In coastal regions, the combined effects of natural processes, human activity, and climate change have caused shoreline changes that may increase in the future. The assessment of these changes is essential for forecasting their future position for proper management. In this context, shoreline changes in the Gulf of California (GC), Mexico, have rec...

Aridity is a condition in which there is a moisture deficit in the air and soil that affects large areas of the earth’s surface worldwide. It is a global problem caused mainly by factors related to climatic events and human actions. In the arid regions of Mexico, prolonged periods of drought are very common and water scarcity is the predominant fea...

This study aims to understand the role of key drivers of historical changes in the shoreline and its implications with the erosion risk in the northern coastal strip of the state of Sinaloa, located on the east coast of the Gulf of California. Digital maps from different years (1981, 1991, 2004, and 2018) are analyzed using geographic information s...

Urban development decreases infiltration, increases the runoff velocity, and reduces the concentration times. This situation increases the flood risk in urban watersheds, which represent a management challenge for urban communities and authorities. To increase the resilience of communities due to modifications of the hydrological cycle produced by...

Arid and semiarid regions are geographic units that cover approximately 43% of the earth's surface worldwide, and conditions of extreme drought and reduced vegetation cover predominate in these regions. In Mexico, arid and semiarid ecosystems cover more than half of the territory, with desertification, mainly caused by anthropogenic activities and...

Anthropogenic activities influence the loss of mangroves, increase natural phenomena such as hurricanes, tropical storms, and El Niño, and consequently increase concentrations of greenhouse gases such as CO2, promoting climate change. There are strategies to reduce emissions from Deforestation and Forest Degradation, the Sustainable Development Goa...

En los últimos años, se ha deforestado el 20% de manglar a nivel mundial. México es de los países con mayor pérdida de superficie de mangle, algo que contribuye a las emisiones de CO2 e impulsa el cambio climático. Sin embargo, falta conocimiento sobre los factores que influyen en la pérdida y la ganancia del manglar, las emisiones de CO2, y la din...

Selective logging in the tropics is a major driver of forest degradation by altering forest structure and function, including significant losses of aboveground carbon. In this study, we used a 30-year Landsat time series (1985–2015) to analyze forest degradation and carbon emissions due to selective logging in a Forest Reserve of the Venezuelan Ama...

The present study focuses on identifying and describing the possible proximate and underlying causes of deforestation and its factors using the combination of two techniques: (1) specialized consultation and (2) spatial logistic regression modeling. These techniques were implemented to characterize the deforestation process qualitatively and quanti...

Deforestation is an anthropic phenomenon that negatively affects the environment and therefore the climate, the carbon cycle, biodiversity and the sustainability of agriculture and drinking water sources. Deforestation is counteracted by reforestation processes, which is caused by the natural regeneration of forests or by the establishment of plant...

The last ten years have shown that Climate Change (CC) is a major global issue to attend to. The integration of its effects into coastal impact assessments and adaptation plans has gained great attention and interest, focused on avoiding or minimizing human lives and asset losses. Future scenarios of mean sea level rises and wave energy increase ra...

Due to an accelerated growth of artificial surfaces, an increasing interest in the changes on land use has been detected in the last decade, making it necessary to propose models able to create plans of optimal and sustainable development. The goal of this work is to identify the potentially most suitable spaces for urban growth, through geospatial...

De este modo, se busca identificar los espacios potencialmente más aptos para acoger el crecimien...

Con base en mediciones y muestreos realizados trimestralmente a lo largo de 18 perfiles de la playa Las Glorias a partir de agosto de 2015 hasta mayo de 2016 y con los datos de oleaje proporcionados por el Instituto Mexicano del Transporte (IMT), por un lado, se analizaron los cambios del perfil de la playa y su relación con el régimen de oleaje qu...

Currently the transformations of land uses are impacting sharply the different ecosystems and their biodiversity. This is why it is important to propose future territorial models to visualize the behavior of different uses and land cover, in order to be able to make decisions at the territorial level and that these are a valuable tool to raise awar...

This paper presents the implementation of a parallelization strategy using the OpenMP library, while developing a simulation tool based on a cellular automaton (CA) to run urban growth simulations. The characterization of an urban growth model CA is shown and it consists of a digitization process of the land use in order to get all the necessary el...

Se analizan las ondas de coda de eventos registrados por la red sísmica de NARS que cuenta con instrumentos instalados a lo largo de ambas márgenes del Golfo de California, México, para estimar atenuación Qc.

In any model, Sensitivity Analysis (SA) is a fundamental process to improve the robustness and credibility of the results, as part of validation procedure. Generally, SA determined how the variation in the model output can be apportioned to different sources of variations, and how the given model depends upon the information fed into it. Many compl...

Over the last few years, urban expansion has occurred without much control or urban planning, causing both regional and global impacts on the natural ecosystems. This situation has spurred reflection on current planning policies and has also stimulated research into new tools and methodologies for the simulation of alternative territorial scenarios...

In any model, sensitivity analysis (SA) is a fundamental process to improve the robustness and credibility of the results. Generally, SA is carried out by testing whether small variations in the input parameters could affect the results of the model. More complex techniques of SA have been developed within the field of numerical modelling; however,...

The design and development of future explorative external scenarios are useful tools for the spatial planning and even more for the metropolitan planning (Peterson et al, 2003; Pettit y Pullar, 2004; Luca, 2007; Carsjens, 2009). However, spatial planning policy and practices in Spain lack of this instruments (Valenzuela, Aguilera, Soria y Molero, 2...

Tis paper describes land use change in the State of Mexico during the period 1993-2002. Changes, interchanges and systematic transitions affecting forest loss were calculated. Multivariant analysis was performed to explain the possible causes that are leading to this regional deforestation process. A detailed description demonstrates that categorie...
