Estrategias de adaptación al cambio climático en el sector agrícola colombiano Laura Camila Bernal Sánchez Física, Astronomía y Matemáticas Agricultura Políticas Públicas Planeación Estratégica Sostenibilidad y Desarrollo Económico Se analizó cómo es el actual desarrollo económico de Colombia en el sector agrícola, puesto que en este se desarrolla una de las actividades económicas con más problemáticas y con una gran expectativa de crecimiento. Además, se identificaron acciones basadas en la Investigación, Desarrollo e Innovación (I+D+I) que deberían implementarse en el sector público y privado para la potencialización del sector agrícola, de modo que éste obtenga un mayor impacto en el mercado nacional e internacional. La metodología utilizada fue descriptiva y se desarrolló a partir de datos estadísticos, ambientales, sociales y económicos que puedan inferir en los actores analizados. Por otra parte, se describieron los impactos que generan los fenómenos climáticos y el déficit en el desarrollo de la infraestructura vial del país, lo cual a su vez provoca un incremento en los costos de producción, que producen un aumento en las importaciones y una dependencia en los alimentos de otros países. Finalmente, se identificarán las políticas públicas del sector agrícola que tienen como objetivo el crecimiento del sector y la mitigación de las problemáticas que este presenta, asimismo se realizó un análisis de cómo estas apoyadas en la planeación estratégica pueden ser más eficientes. 2023 artículo científico 2664-0880 https://www.redalyc.org/articulo.oa?id=701977565003 https://www.redalyc.org/journal/7019/701977565003/ https://www.redalyc.org/journal/7019/701977565003/html/ https://www.redalyc.org/journal/7019/701977565003/701977565003.epub https://www.redalyc.org/journal/7019/701977565003/movil es http://www.redalyc.org/revista.oa?id=7019 Revista cubana de meteorología application/pdf Instituto de Meteorología de la República de Cuba Revista cubana de meteorología (Cuba) Num.3 Vol.29
