| description | The changes in land use generated by the development of human activities have accelerated the loss of vegetation cover. Due to its location on coastal plains, mangrove coverage has been one of the most affected in recent years. The main changes have been made evident by aquaculture, agriculture, and tourism. The loss of mangrove swamps entails changes in the climate at the local scale, which affects variations in the water cycle and the saline balance of the coastal lagoons, inciting a domino effect on biodiversity, soils, and therefore economic activities. The objective of this work was to evaluate the change in coverage and land use of the coastal plain of San Blas, Nayarit from the period 2000-2019 and its trend for 2038. The method used was the supervised classification of satellite images in a GIS and the Markov chains tool for future projection. An increase in areas for shrimp farming was found (4.3%), which led to the displacement of flood zones, possible associated with impacts on the hydrologic system, causing a reduction in mangrove cover (4.7%), however, it is expected that the trend will continue to a lesser extent up to 2038. This conclusion is expected to be a reference for future decisions on the development of anthropogenic activities in this area and others in the coastal plain. |

Los cambios de uso de suelo generados por el desarrollo de actividades humanas han acelerado la pérdida de cobertura vegetal. Por su ubicación en las llanuras costeras, la cobertura de manglar ha sido una de las más afectadas en los últimos años. Los principales cambios se han evidenciado por actividad acuícola, agropecuaria y turismo. La pérdida de manglar trae como consecuencia modificaciones del clima a escala local, lo que repercute en variaciones del ciclo hídrico y balance salino de las lagunas costeras, propiciando un efecto dominó sobre la biodiversidad, los suelos y por ende las actividades económicas. El presente trabajo tuvo como objetivo evaluar el cambio de cobertura y uso de suelo de la llanura costera de San Blas, Nayarit, del periodo 2000-2019 y su tendencia para el 2038. El método empleado fue la clasificación supervisada de imágenes satelitales en un sistema de información geográfica y la herramienta cadenas de Markov para la proyección futura. Se encontró aumento de áreas de camaronicultura de 4.3%, lo que llevó al desplazamiento de zonas inundables, posiblemente asociado a impactos en el sistema hídrico, provocando una reducción de la cobertura manglar de 4.7%, sin embargo, se prevé que la tendencia continuará en menor magnitud para el 2038. Se espera que esta conclusión sea referente para las decisiones futuras sobre el desarrollo de actividades antropogénicas en esta área y otras de llanura costera.
