Article
Full-text available
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...
Article
Full-text available
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...
Article
Full-text available
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...
Article
Full-text available
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...
Article
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...

Debido al crecimiento acelerado de superficies artificiales, en las últimas dos décadas se ha observado un creciente interés en los cambios de uso de suelo, lo que hace necesario establecer modelos que generen planes de desarrollo óptimo y sustentable. De este modo, se busca identificar los espacios potencialmente más aptos para acoger el crecimien...

Full-text available
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...
Article
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...

Coda waves were analyzed from events recorded by NARS seismic network deployed along both margins of the Gulf of California, Mexico, to estimate coda attenuation Qc. Sato’s (1977) single scattering model was used for a coda window of 20 to 25 s beginning at twice the S-wave travel time. Events recorded from 2003 to 2007 located in the central regio...

El objetivo de esta investigación fue estudiar la deforestación y sus causas en el estado de Sinaloa, México. Para ello, se utilizó la cartografía de Uso de Suelo y Vegetación del año 1993 y 2011 a escala 1:250 000, con esta se estimó la deforestación mediante una técnica de detección de cambios; posteriormente, se caracterizó la deforestación medi...
Article
Full-text available
In the last years the whole planet has been suffering remarkable changes, including the land use and cover, and that this is one of the many components of the global change. The present study has as main objective described the changes of land use and cover occurred in the State of Sinaloa during the period 1976-2011. For this, we used 4 maps of la...
Conference Paper
Full-text available
The purpose of this research was mainly studying changes in forest cover and its causal factors in the state of Sinaloa, Mexico. To do this, mapping of land use and vegetation in 1993 and 2011 was used a scale of 1: 250,000, this deforestation was determined roughly using a technique of detecting changes; Later, the change matrix was applied to ana...

Para la detección de áreas quemadas se evaluaron 30 variables continuas que incluyeron las bandas originales de una imagen Landsat 5 TM y otras derivadas de estas, como los índices de vegetación y de áreas quemadas, divisiones entre bandas, análisis de componentes principales, tasseled cap y análisis de mezclas espectrales. Con el propósito de dete...

The main objective of this research is to analyze deforestation in State Sinaloa during the period 1990-2014. For this, " deforestationhot-spot areas " were identified, by crossing maps of 1993 and 2011 at a 1:250,000 scale with knowledge from environmental and forest experts from each region. Landsat images from 1990 and 2014 and Terra Amazon Syst...

La desertificación es un proceso complejo, involucra factores ambientales y antro- pogénicos dentro de un contexto climático seco. Dispone de una importancia glo- bal, dado que reduce la productividad y el valor de los suelos ocasionando un impacto sobre el territorio y su población. Las Tecnologías de Información ayudan a identificar zonas propens...

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...
