Phytoremediation is an environmentally friendly, economical, and sustainable technique for restoring farmland. It can remove heavy metals and organic pollutants from the soil through the implementation of hyperaccumulator plants. In recent years, it has garnered significant interest from academic and industrial sectors. This article screened 368 research papers from the Web of Science core collection database related to farmland phytoremediation and conducted a bibliometric analysis of the domain based on CiteSpace. The paper intuitively demonstrates the most influential countries, the most productive institutions, the most contributing groups of authors, and the primary sources of farmland phytoremediation research domain. The findings additionally indicate that the research hotspots include: (1) mechanisms and principles of phytoremediation, (2) the improvement of restoration efficiency, (3) the economic, ecological, and sustainable development of phytoremediation. The exploration of plants with potential to accumulate heavy metals and produce large amounts of biomass is the research frontier within the field of farmland phytoremediation. Additionally, this bibliometric analysis can help scholars willing to work in this research field by concisely understanding the overall research field and frontiers. With the continuous improvement of phytoremediation and its combination with other remediation technologies, the future of farmland remediation will have a promising prospect.

CRISPR/Cas9 has emerged as the predominant method for genome editing due to its cost-effectiveness and broad applicability, playing a crucial role in advancing sustainable practices across various sectors. This systematic review employs the PRISMA methodology to evaluate the impact of CRISPR/Cas9 on environmental protection and on achieving Sustainable Development Goals (SDGs) such as SDG 2, 3, 6, 7, 9, 12, 13, and SDG15. These goals focus on the responsible use of natural resources, reducing the negative effects of climate change and ensuring safe food for the entire population. Analyzing data from the Web of Science, the review found significant growth in related publications, with a 30% increase since 2014, predominantly from the US, China, Germany, and the UK. The study categorizes the scientific developments into these trends, the enhancement of plant tolerance to environmental stresses, as evidenced by the consistent focus on terms such as “tolerance” and “plant” since 2021. Furthermore, the relevance of “Gene Editing” has increased significantly since 2022, underscoring the importance of CRISPR/Cas9 in developing resilient crops that can withstand extreme conditions. These trends underscore the growing significance of biotechnological advancements in the mitigation of climate change’s effects and the improvement of ecosystem stability. Key discussions include CRISPR/Cas9’s role in the development of fourth-generation biofuels and environmental biosensors, as well as its applications in enhancing genetic resilience and controlling invasive species. These innovations highlight CRISPR/Cas9’s potential in promoting sustainable resource management and energy generation, making a significant contribution to ecological conservation and sustainability efforts.

La Biotecnología Ambiental emplea el uso de organismos para la prevención, monitoreo y remediación de los ecosistemas, al mismo tiempo permite la generación de bioproductos y energía limpia. El libro consistió en tres capítulos, en el primero se establece los fundamentos de la Biotecnología Ambiental y sus aplicaciones en entornos terrestre, acuático y aéreo; además, se presentan herramientas aplicadas como los biosensores en el monitoreo ambiental, la fitorremediación en varios contextos de América Latina y el fortalecimiento de la agricultura sustentable. En el segundo capítulo se describe la importancia de un estudio bibliométrico y el enfoque para las diversas investigaciones, se detalla un manual de uso, que permite su replicabilidad en otros contextos. Además de presentar un caso de estudio aplicado al tema central de este libro, que sistematiza los temas más estudiados, las tendencias, revistas y países con mayores contribuciones. En el tercer capítulo se presentan varias prácticas de laboratorio y una sección de preguntas, que pueden ser empleadas en otras instituciones educativas o de manera autónoma. En conclusión, los capítulos son complementarios entre sí, facilitando la comprensión e interés del lector. El área de mayor relevancia corresponde a la biorremediación en suelos contaminados por hidrocarburos y metales pesados, los grupos más frecuentes en la revisión fueron hongos, cianobacterias y organismos genéticamente modificados. Finalmente, existe una oportunidad del uso y la potencial combinación de las técnicas basadas en metagenómica, ADN ambiental, inteligencia artificial para el desarrollo de las nuevas tendencias de la Biotecnología Ambiental

Population growth has significantly increased energy and resource demands, driving research toward cost-effective technologies that repurpose waste into alternative energy forms such as biohydrogen. This review aims to comprehensively evaluate biohydrogen production via anaerobic digestion, addressing gaps in previous studies focusing on a single sustainable development goal or limited environmental benefits. The methodology used the Scopus database with specific keywords, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol to screen relevant articles, and bibliometric analysis to delineate research directions from 2002 to 2024. Findings indicate that research on biohydrogen production via anaerobic digestion has grown exponentially over the past two decades, with increasing emphasis on advanced techniques, innovative reactor configurations, and diverse microbial consortia. Emerging trends, including the integration of artificial intelligence for process optimization and comprehensive life cycle assessments, suggest promising avenues for large-scale implementation. Anaerobic digestion-based biohydrogen production supports several Sustainable Development Goals (SDGs), including the ones related to clean energy (SDG7), SDG 13 (climate action), and SDG 12 (waste management), among others. Recent advancements are synthesized to provide a clear roadmap for future research toward sustainable energy solutions.
