Contribución para el conocimiento del escenario de riego mediante el análisis multitemporal de imágenes satelitales del río Cauca en el sector de Villa Paz, municipio de Jamundí
(Universidad Santiago de Cali, 2020) Guevara Garcés,Angie Vanessa; Melo Vargas, Andrés Felipe
The Cauca River is characterized by being sinuous and alluvial, which implies a great mobility of its channel; The sinuosity of a channel is the mechanism by which a river adjusts its slope when the valley through which it flows is greater than necessary, during its floods they favor the occurrence of floods of the lands used for socioeconomic activities and established villages that are in the banks of the river causing damage to the territory. (López JD, 2011) A contribution was made to the identification of risk setting, risk analysis and evaluation in the village of Villa Paz, and contributed to the Risk Awareness process that feeds the risk reduction and risk reduction processes. Disaster management, a research work is presented, the general objective of which was to analyze the dynamics of the Cauca River in the village of Villa Paz, Jamundí municipality, through the multitemporal observation of satellite images to identify risk setting. To do this, using current remote sensing techniques incorporated into geographic information systems, thematic maps were created with information from NASA satellite images and aerial photographs from the United States Geological Survey USGS; from sensors such as Modis, Globe and Landsat, obtained through the Google Earth Pro platform, and an analysis of the dynamics of the Cauca River was carried out in different periods of time, measuring the ranges and rates of annual displacement of its banks, and Establishing the movement vectors for the displacement of the riverbed, an analysis was also carried out on the threat of flooding in the study area. The results obtained in this work open very positive perspectives for the application of remote sensing in the orientation of strategies for risk monitoring and in the processes of formulating, executing, monitoring and evaluating risk management
Análisis de cambios de coberturas en dos áreas de compensación forestal ubicadas en los municipios de la Cumbre y Dagua en el departamento del Valle del Cauca durante los años 2013, 2014 y 2020
(Universidad Santiago de Cali, 2020) Pérez Durán, Igor Ephanor; Melo Vargas, Andrés Felipe
Coverage layers were generated on two lands in forest compensation called Villa María in the municipality of Dagua and also the Santa Fe estate in the municipality of La Cumbre, department of Valle del Cauca - Colombia. Coverages were generated for March 2020 (both properties), for December 2013 (Villa María) and August 2014 (Santa Fe) applying a supervised classification and implementing the Corine land cover classification legend adjusted for Colombia (CLC Colombia). In addition to updating coverage to 2020, a comparison was made with the periods 2013 and 2014, which were the initial years of the beginning of these compensations, and through this comparison the increase or decrease in coverage generated by the implementation of the compensation measure focused mainly on a forest restoration strategy. It could be determined that during the multitemporal analysis period (6-7 years) Increases in grassland coverings occurred mainly in exchange for a decrease in grassland-type coverings. However, there were increases in unwanted coverage in the processes of plant succession as the case of increased fern coverage, while for some sectors there was a decrease in tree cover. In this way, 50% of the areas developed positive changes that contribute positively to achieving more advanced successional states, but between 40% and 43% present a stagnation or deterioration in the desired process of plant succession, so it is recommended to implement measures to eradicate unwanted cover (mainly fern), planting of pioneer species and high-density afforestation in sectors with low changes in cover.

(Universidad Santiago de Cali, 2020) Rivera Paja, Albin Oswaldo; Melo Vargas, Andrés Felipe
Geographic Information Systems (GIS) today have become a powerful tool to predict phenomena in any field of science, however, they have gained greater strength in environmental sciences, mainly in land and resource administration. natural. To demonstrate the effectiveness of GIS in making institutional decisions, a soil zoning methodology was designed, taking as a case study the Amaime Basin of the municipality of Palmira, and where, based on processing and crossings of different concepts and geospatial characteristics, it is possible to identify the environmental offer that these soils have, the critical zones and their respective edaphic zoning. Said zoning alludes to the grouping of soil-forming and deforming factors, in addition, it provides information on the current and future conditions of the ecosystem that makes up the study area, and allows establishing actions in an effective and timely manner that promote conservation, protection and sustainability of the territory under study. The processing, from the GIS, of the secondary information of the Amaime Basin of the Palmira municipality, obtained from Departmental and National territorial entities, shows as a result that this Basin is rich in both types of soil, as well as in ecosystem biodiversity, which In turn, each of these components and their intersection present essential characteristics that determine the type of use, the favorable and unfavorable conditions that must be taken into account, how anthropic settlements behave at this time and should improve their , to mitigate the environmental damage practices of this Basin.

(Universidad Santiago de Cali, 2022) Tabares Mosquera, Mauricio; González Velandia, Francy Juliana; Giraldo Restrepo, Juan Carlos
Geographic information systems and remote sensing are frequently used as support in land planning, field work and the study ofchanges over the surface of the Earth. The method of calculating and classifying spectral indices is widely used to characterize large areas in a specific time period, allowing trends to be identified and changes in land use and cover to be monitored. This study analyzed the vegetation and the phenomenon of land conversion in four hydrographic basins of the Catatumbo region, Norte de Santander, Colombia, using SENTINEL-2 images captured in the years 2019 and 2022, which, after undergoing corrections, were used to calculate and compare NDVI and SAVI spectral indices. In this process, a Python language script was programmed to develop an ArcToolbox geoprocessing tool. With this tool, two scenarios were evaluated to estimate the influence of the expansion of the agricultural frontier and the urban centers of the study area. During the study period, while forest cover was reduced by 334 km2, grasses and shrubs grew by 260 km2, evidence of land conversion in this area with a significant presence of oil palm cultivation, illicit crops, and livestock activity. The validation stage showed an accuracy of 84% for the land cover generated by the model compared to the official land cover layer of Colombia Corine Land Cover
Identificación de áreas para la siembra de especies forestales nativas en el bosque seco tropical del Valle del Cauca: una aplicación de los sistemas de información geográfica
(Universidad Santiago de Cali, 2023-02-15) Celorio Mosquera, Leidy Janeth; Cardona Zea, Diana Amparo
The Valle del Cauca is one of the few departments in Colombia that has the dry tropical forest ecosystem, however, its coverage is limited to small areas due to high degradation rates and the loss of biodiversity due to anthropogenic factors. In this project, priority planting areas, nurseries, and plant species that could be relevant in ecological projects for these ecosystems were identified. The multicriteria analysis was implemented to obtain the areas of interest (the evaluated criteria were degradation and soil use, distance to water sources, roads, and forest fragments); and species selection criteria based on their threat category, use, resistance, among others. The results show that 148 plant species meet the necessary criteria to be ideal in the plantings carried out in these ecosystems due to their ecological and cultural importance. Likewise, a local network of 69 nurseries was identified for the acquisition of these species, which can be strengthened and consolidated in the long term. In addition, 58,509 hectares were divided into 281 possible sites in the territory that could be intervened. This project generates valuable information on the use of geographic information systems (GIS) tools as a key complement in conservation strategies for tropical dry forests in Valle del Cauca

(Universidad Santiago de Cali, 2023-02-21) Ramírez Calderón, Luis Andeimer; Rojas Montes, Javier Salvador
The Analysis of the spatial distribution of the data on the occurrence of Mass Movements makes it possible to identify their distribution through the application of spatial statistical tools for the analysis of patterns. The materialization of the phenomenon brings with it different social, physical and economic problems. Therefore, this article aims to make visible from a geographical perspective the occurrence of the phenomenon through the identification of the spatial distribution with the data provided by the Secretariat of Emergency and Disaster Risk Management of Santiago de Cali between the years 2019 to 2021. , case of Commune 20. With the data shared by the institution, a spatial analysis was carried out: autocorrelation and spatial patterns, in contrast to the zoning of threat and risk mitigable by mass movements of the official information of the current Land Management Plan. Spatial autocorrelation makes it possible to determine the degree of association (influence) that a geographic phenomenon presents between the defined analysis units, considering its vicinity and explaining the behavior and distribution of the phenomenon within the geographic framework. The results obtained with the application of spatial autocorrelation techniques allow the identification of a conformed spatial structure. This article is an important input for decision-making in relation to prevention and risk reduction actions.
Zonificación a través de las herramientas sig para conocer la calidad ambiental de cinco zonas de la franja protectora del río Cali en su trayecto urbano
(Universidad Santiago de Cali, 2023-02-22) Sierra Gómez, César Augusto; Orozco Ordoñez, Iván
The present research had to establish a zoning through GIS tools in order to know the environmental quality of five zones along the protective strip of the Cali river in its urban route, to provide useful tools for intervention in environmental corridors. of urban rivers. The first thing that was done was to identify the coverages that were used from field trips and with the Google Earth geo viewer, which provides images that are useful for digitizing the coverages in vector format, to later convert them to raster and then performed the weighted linear summation where a raster was obtained that gives us a possible environmental quality. Regarding the results, in general, they showed that the environmental state of these five areas is linked to aspects such as: conflicts due to land use, housing density and social factors. In this sense, we found that good environmental quality is associated with variables such as good vegetation cover (in the form of a boulevard or gallery forest), maintenance and cleanliness of green areas, presence of places of common or tourist interest. On the contrary, the areas that have a low environmental quality have sparse vegetation that lacks connectivity and little maintenance or care of the Strip, in addition to a low social stratification in which dwellings occupying the environmental protection zone of the river predominate. this changing a series of socio-environmental problems
Estimación de la superficie deforestada en el Parque Natural Nacional la Paya mediante el uso de Sensores Remotos para el periodo 2018-2022
(Universidad Santiago de Cali, 2023-02-22) Espinosa Valencia, Camilo Eduardo; Cabezas Alzate, Diego Fernando
Deforestation on protected areas becomes an environmental problem in which forest cover is exchanged for other types of surfaces such as livestock, crops or pastures. In the case of Colombia, the environmental entities in charge of managing and protecting the areas declared as National Natural Parks are the National System of Protected Areas (SINAP) and the Institute of Hydrology, Meteorology and Environmental Studies (IDEAM). Although these entities carry out quarterly controls and estimate forest losses in these protected areas, historical results show an upward trend in deforestation rates, generating environmental damage that directly affects nearby communities and resources in general. from the country. This study presents a low-cost monitoring based on remote sensors and Landsat 8 and 9 satellite images that allows quantifying forest losses with a higher temporality and a spatial resolution of 30 meters. The procedure includes the download and processing of the images within the Paya National Natural Park, for the period 2018-2022 and subsequently a supervised classification that discriminates the coverage into 2 classes, defined as forest and non-forest. Finally, a subtraction is made of the polygons classified as forest on the initial (USGS, 2022) and non-forest on the final date to quantify and locate the deforested areas within the park. The results show to be a successful method to identify coverage changes, however, the precision is limited by the cloudiness of the area and the spatial resolution, which generates alterations in the limits of homogeneous coverages.

(Universidad Santiago de Cali, 2023-03-06) Fernández Noguera, Edwin Nayi; Rojas Montes, Javier Salvador
Modern society has generated environmental damage due to the overexploitation of natural resources, as evidenced by natural phenomena such as climate change on the planet. However, one of the main causes is the deforestation of forests and industrial activities in ecosystems that are fundamental for the survival of life, in this case, the activities are intensely observed in poor countries such as Asia, Africa and South America in the Amazon. As mentioned, the extractivist economic model has a negative impact on natural environments, for this reason, this research performs a multitemporal analysis with ArcGIS and Qgis software with which Landsat satellite images will be processed to structure the supervised classification for the years 2001, 2009 and 2019, thus, identifying the types and changes of coverage in the village of Las Guacas in the municipality of Popayán, but also, trying to determine the effects they cause in the middle basin of the Las Piedras River, which supplies the municipality of Popayán. With the results, it is intended to demonstrate the modifications in the study area, both positive and negative in the different forests, crops and the impacts that have been generated over time
Propuesta metodológica para el cálculo del número de curva CN usando sistemas de información geográfica, en cuencas del Valle Geográfico del Alto Cauca, caso de estudio Cuenca del Río Palo
(Universidad Santiago de Cali, 2023-03-13) Coral Huertas, Cristian Alejandro; Zapata Echeverri, Walter Stanley; Rojas Montes, Javier Salvador
Geographic Information Systems (GIS) and Hydrology are two fields of work that share many interests, given the need to spatially represent different variables, necessary for the modeling and study of various hydrometeorological events or engineering projects. For this reason, the present research work proposes, under the framework of GIS, the construction of a methodology to determine the direct runoff in basins of the Geographic Valley of Alto Cauca, this parameter being a key factor in hydrological modeling, known as the Curve Number “CN”. Obtaining it by the traditional method of analog superposition of variables is very tedious, increasing the time and complexity of the modeling. The CN parameter is a conceptual model of precipitation losses, whose objective is to estimate the volumes of surface runoff, depending on the slope, use, type and condition of the soil, information that thanks to the evolution of GIS and other Geomatic tools for the capture and analysis of geospatial information are increasingly available and updated in compatible formats for different analyzes and geo processes. Taking into account the above, the main objective of this work is to present a method for obtaining CN using the ArcGIS 10.8 GIS software and adjusting the prime number methodology proposed by Ferrer et al (1995) for soils in the United States, making the equivalence for the soils of the Geographic Valley of Alto Cauca and in this way to obtain the spatial distribution of the CN parameter more quickly, economically and accurately in the basins of this region of Colombia. . As a pilot test, the selected methodology was applied to the Palo river basin of the Geographic Valley of Alto Cauca, the calculated CN values were adjusted based on the slope from the digital elevation model and were weighted to obtain a single CN value for the entire basin.

(Universidad Santiago de Cali, 2023-09-13) Arango Cifuentes, Andres Mauricio; Orozco Ordoñez, Iván
The open-pit coal mining in the La Guajira department has experienced significant growth in the last four decades, raising questions about the extent and consequences of vegetation loss in the region. The aim of this study is to conduct a multitemporal analysis of changes in vegetation cover in the El Cerrejón coal mines and surrounding areas from 1985 to 2023. By utilizing geospatial analysis techniques in the open-source software QGIS and satellite imagery from Landsat and Sentinel remote sensors, subsequently processed with the Semi-Automatic Classification Plugin (SCP), graphical outputs were obtained to quantify and evaluate historical changes in the study area, as well as understand the spatial and temporal behaviors of observed changes. This multitemporal analysis provides a deeper insight into the magnitude and dynamics of changes in vegetation cover due to mining exploitation. The results of this analysis are expected to contribute to a better understanding of the environmental impacts of extractive activities in the La Guajira department, providing essential information for environmental management decision-making. Likewise, it is anticipated that this study will serve as a scientific basis for the implementation of mitigation and ecological restoration strategies in areas affected by vegetation loss.

(Universidad Santiago de Cali, 2023-10-31) Arroyo Alomia, Mario Alfonso; Orozco Ordoñez, Iván
The district of Buenaventura, in coordination with the competent entities of the department of Valle del Cauca, in relation to its functions, has the obligation to ensure the preservation and conservation of the environment, renewable and non-renewable natural resources that are within the limits of the district, in addition to that, the district has a rural and suburban territorial extension of 6,653 km2, which represents 94% of the total territorial extension. The rural area is characterized by containing riches in flora and fauna. In rural areas there are settlements of black and indigenous communities that, as a community, have long had their social and cultural customs, their special way of carrying out economic activities, and their medicinal uses. . traditional everything included in an ancestral culture of the same, currently necessary actions are carried out that lead to constant maintenance of the water resource; From this we see the need to carry out the characterization of the water sources so that they serve as input for the constant maintenance and good use of the water resource that abounds in the district, and the conservation of the environment. The present research work fully seeks the identification in detail of the water sources of the Community Councils located in the internal maritime bay of the Special, Industrial, Port, Biodiverse and Ecotourism District of Buenaventura that allow the preservation, care, conservation and use in a manner appropriate of them.
Accesibilidad espacial desde los barrios a las Instituciones Educativas Oficiales del distrito de Buenaventura
(Universidad Santiago de Cali, 2023-11-02) Guerrero Leudo, Andres Felipe; Orozco Ordoñez, Iván
This study addresses accessibility to public educational institutions in Buenaventura, Colombia, using four measurement methods. Despite the importance of education as a fundamental right, challenges are identified in terms of its accessibility in this region, marked by the Afro-descendant and indigenous population and high levels of poverty. Accessibility is assessed using isochronous, Hansen, Hansen population-adjusted indicators and Integral Route Factor. The results reveal that the majority of the population lives in areas with a regular road network, which facilitates accessibility to official educational institutions. However, there is a disparity in accessibility, with the central neighborhoods being the most accessible and the peripheral neighborhoods and in the western area the least accessible due to the lack of nearby educational centers. In addition, areas with different levels of mobility to official educational institutions are identified. The analysis also shows relationships between accessibility indicators, such as the correlation between Hansen and Hansen adjusted for population. However, no significant association was found between Hansen and the Integral Route Factor. This study offers valuable considerations and conclusions to guide policies that promote equality and access to education in Buenaventura. The quality of the road infrastructure is highlighted as a key factor in accessibility, and it is emphasized that a high accessibility index does not guarantee quick access to educational centers if the necessary services are not offered.
Determinación de áreas de afectación por presencia humana, en los sitios de importancia para las aves playeras en el Delta del Rio Iscuandé y PNN Sanquianga del departamento de Nariño - Colombia.
(Universidad Santiago de Cali, 2024-04-26) Cuervo Ferrin, Cindy Marcela; Escalante Caicedo, Ana Bely
The Pacific coast of Nariño, Colombia, is a region with a high biodiversity potential, in which two important areas have been identified for the conservation of shorebirds. Highlighting the Bocana del Río Iscuandé as the first site of regional importance for the Hemispheric Network, has an area of 12712 ha in the information extracted by the ArcGis and is used by more than 50,000 shorebirds a year, hosting to date 22 different species, including the plover piquigrueso (Charadrius wilsonia) and the western sandpiper (Calidris mauri). Sanquianga National Natural Park covers approximately 53% of the mangroves in the department of Nariño and 20% of the mangroves in the Colombian Pacific, making it a highly productive and biodiverse ecosystem. This park covers an area of 80,000 hectares and is a site of international importance for WHSRN (Western Hemisphere Shorebird Reserve Network). In addition to this, it should be noted that within each of these areas, there are specific feeding and resting sites for shorebirds, which were taken into account for these analyses. Human disturbance of natural areas causes, to a large extent, the loss of habitat and the birds' stay in the area. On the other hand, airstrips allow us to evaluate the accessibility of the sites for tourists, since they offer a direct and convenient way to access remote and difficult to reach areas. In addition, the beaches variable allows us to identify how accessible the beaches are for the people who live in the area. To understand the magnitude of the effect of human disturbance on shorebird concentration sites, a geographic perspective was used to analyze the level of disturbance to the sites. Two components of disturbance were selected: connectivity (airstrips) and tourism supply (beaches and population centers). Once these components were defined, spatial analyses were carried out to evaluate the proximity of the variables as a measure of influence. Finally, the areas affected by the sites in relation to each variable were determined. The spatial analyses consisted of using areas of influence of different radii to evaluate the proximity of the variables to the sites, defining proximity as the largest radius of incidence. This was carried out using ArcGIS Pro software and the Buffer and Selection by Location tools. This analysis provides valuable information for future decision making in terms of conservation of natural areas. Ultimately, this article shows the usefulness of GIS as an effective decision-making tool.
Zonificación de áreas adecuadas para densificación urbana mediante el uso de SIG en el municipio de Pereira, Risaralda
(Universidad Santiago de Cali, 2024-04-26) Restrepo Velásquez, Juan José; Escalante Caicedo, Ana Bely
Currently, urban growth is a matter of great importance due to the increasing demand for housing and commercial spaces in urban areas. Urban densification has become an alternative to maximize available spaces and reduce city expansion into rural areas, which are often classified as ecologically important land. However, city planning, and land use management are complex processes that require the collection, analysis, and systematization of large volumes of data and other relevant factors. In this context, the application of techniques such as multicriteria analysis and Geographic Information Systems (GIS) allows for the selection and prioritization of relevant factors for identifying the best areas for urban densification. Additionally, the generation of data processing models and zoning maps to define optimal areas facilitate decision-making for urban planning. This research proposes a methodology for identifying suitable areas for urban densification in the urban center of Pereira, Risaralda municipality. Relevant data and factors related to city land use will be collected, systematized using GIS tools to visualize and analyze the collected data along with identified areas, areas with low construction density will be identified, and specific recommendations for urban densification in identified areas will be proposed. In conclusion, the application of GIS techniques and multicriteria analysis allows for more efficient and sustainable urban planning, contributing to the development of more livable and environmentally friendly cities.
Análisis de factibilidad para la localización de las centrales eléctricas con las energías renovables eólica y/o solar en el Valle del Cauca
(Universidad Santiago de Cali, 2024-04-26) Lemos Garcia, Natalia; Rojas Carvajal, Sharon Andrea; Escalante Caicedo, Ana Bely
This study focuses on conducting a feasibility analysis to determine the suitable location for solar and wind power plants in the Valle del Cauca region. The methodology employed integrated Geographic Information Systems (GIS) and Multicriteria Analysis, highlighting the importance of weighting critical variables in the process of identifying optimal locations. The methodology involved defining and weighting specific selection and restriction criteria for each type of power plant. The application of map algebra facilitated the identification of ideal zones for the installation of power plants utilizing solar or wind resources, establishing a threshold of equal to or greater than 0.9 to determine optimal areas. This approach revealed that the ideal areas for solar power plants are in the north-central region of the department. Additionally, it was identified that the Valle del Cauca lacks the necessary conditions for the installation of large-scale wind farms. This study underscores the viability of harnessing renewable sources, particularly solar energy, in identified specific areas. However, it highlights the challenges and limitations associated with optimal location for large-scale wind farms in the region, emphasizing the need to consider both the energy generation potential and the geographic restrictions and infrastructure criteria when planning renewable energy projects in the Valle del Cauca.
