“…To create a rainfall map, climate information was gathered from the Sebou Basin Hydraulic Agency (ABHS). To preprocess and interpolate the rainfall datasets, we used the Kriging geostatistical method, which is renowned for its excellent accuracy when estimating the interpolated data [4], [7], [9]. The lithological map was created by digitizing the geological map of [14].…”

This study aims to model the groundwater storage areas in the Guigou basin using Geographic Information System (GIS), Remote Sensing (RS) and AHP methods. Eight thematic maps of lithology, slope, rainfall, rock fracture, Fractional impervious surfaces, LU/LC, soil and drainage were respectively classified and weighted and then used to create the map of potential groundwater storage areas. The results have shown that the area of Medium, high, and very high potential zones make up 66.38%, 11.43%, and 0.048% of the total, respectively, while medium and low potential zones make up 22.14% and 0.002% of the total. The obtained results have been validated with 51 wells in the study area. It indicates a clear correlation between the groundwater potential zones and the wells depth, This relationship between depth and location of drilled wells is particularly clear; in fact, the majority of shallow wells are found in places with high potential, whilst the majority of deep wells are found in areas with low potential.

“…Geology has a signi cant role in choosing the location of groundwater storage because it affects water ow and in ltration [4][5][6][7][8][9]18]. The permeability and porosity of a rock formation, both of which are connected to its lithology, also in uence whether it is suitable for its de nition as an aquifer [21].…”

“…Sistem Informasi Geografis (SIG) merupakan sebuah sistem informasi khusus yang mengolah data dengan informasi yang bereferensi keruangan (data spasial). Ini berarti SIG memiliki kemampuan untuk membangun, menyimpan, mengelola dan menampilkan informasi bereferensi geografis, misalnya data yang diidentifikasi menurut lokasinya, dalam sebuah basis data [3]. Teknologi GIS menggunakan informasi digital yang didapatkan dari metode pembuatan data digital [4].…”

Nowadays people have started to realize the importance of health. Everyone wants to quickly find out where the right doctor is if they want to get health services or have shown certain symptoms of illness. This research resulted in an application called "find doctor" which aims to be able to find the location and information of the doctor closest to the user while in the city of Padang. This study adopted stages of the Waterfall Model and was built using the Location Based Service method provided by Android. This application is built from two sides, namely the android client and the web server. This research produces an application that can find the location and information of the desired doctor's practice in the city of Padang. Applications that can be accessed using an internet browser (server) and android smartphone (client) with a minimum Android 5.0 operating system.

“…Al mismo tiempo, para conservar la biodiversidad en la actualidad se están empleando herramientas integradoras, como la planificación sistemática de la conservación (PSC), que en poco tiempo se ha convertido en un estándar para diseñar y evaluar iniciativas de nuevas áreas de conservación [22], ya que es un proceso de apoyo [23], que ofrece conceptos y cajas de herramientas para tomar decisiones espaciales sobre dónde enfocar los esfuerzos y al mismo tiempo, minimizar una variedad de costos para las partes interesadas [24,25]. Agregando a lo anterior, el empleo de sistemas de información geográfica (SIG), como herramienta de planificación para salvaguardar la biodiversidad permite almacenar, analizar y procesar la información desde múltiples dimensiones [26], siendo en ocasiones el único método que proporciona soluciones específicas a problemas que no podrían resolverse con métodos convencionales [27], por tanto, se recomiendan a los tomadores de decisiones que planifican de forma remota la conservación y la gestión [28].…”

The identification of conservation gaps through a systemic planning process allows for the design and evaluation of initiatives for determining conservation areas at different geographical scales. The purpose of this study was to determine the conservation gaps associated with threatened wildlife in Chimborazo, Ecuador. A documentary research was used including a systematic review of 26 geographic and bibliographic information sources on 10 wildlife variables, a multicriteria analysis in GIS using six criteria, the statistical analysis of independent variables using a Chi-square test, and the development of a correspondence analysis. The results showed that in Chimborazo province, 311 species of wildlife were registered, of which 13% are in a degree of threat. To mitigate the problems associated with the loss of wildlife, two strategies are required, mainly through the leadership and active participation of the 10 public sector actors. In addition, it was identified that the conservation gaps associated with threatened wildlife are mainly found in the “paramo” ecosystem and comprise an area of 143,302 ha, which corresponds to 22% of province’s extension. This information should be used by the institutions related to the management of the natural resources of the province to deepen the studies on the ranges of distribution of species in threat category and promote actions that allow the conservation and sustainable use of the natural heritage from the province. Keywords: Fauna, Threats, Conservation gaps, Multi-criteria analysis. Resumen La identificación de vacíos de conservación a través de un proceso de planificación sistémica permite diseñar y evaluar iniciativas para la implementación de áreas de conservación en diferentes escalas geográficas. El propósito de este estudio fue determinar los vacíos de conservación asociados a la fauna con categoría de amenaza en la provincia de Chimborazo. Los métodos empleados contemplaron una investigación documental, mediante la revisión sistemática de 26 fuentes información geográfica y bibliográfica sobre 10 variables de la fauna, un análisis multicriterio en SIG a través de la aplicación de 6 criterios, y el análisis estadístico, mediante la aplicación de una prueba chi cuadrado de independencia y el desarrollo de un análisis de correspondencia. Los resultados reflejan que en la provincia de Chimborazo se registraron 311 especies de fauna, de las cuales el 13% se encuentran en una categoría de amenaza. Para mitigar la problemática asociada a la perdida de fauna silvestre se requiere la implementación de dos estrategias, a través del liderazgo y la participación de 10 actores del sector público, principalmente. Además, se identificó que los vacíos de conservación asociados a la fauna con categoría de amenaza se encuentran principalmente en el ecosistema páramo y comprende una extensión de 143.302 ha, que corresponde al 22 % de la extensión de la provincia. Esta información debe ser utilizada por las instituciones relacionadas al manejo de los recursos naturales de la provincia, para profundizar los estudios sobre los rangos de distribución de especies en categoría de amenaza, y para impulsar acciones que permitan la conservación y el aprovechamiento sostenible del patrimonio natural de la provincia. Palabras Clave: Fauna, Amenazas, Vacíos de conservación, Análisis multicriterio.
