Currently, climate change and population growth have a significant impact on human beings. Furthermore, these factors are generating a great need for energy to sustain present-day pace of life. For this reason, this research aims to determine the wind potential of the city of Chachapoyas, through the study of wind direction and speed using a wind rose. Data were obtained from the Metrological Station located on the University Campus of the National University Toribio Rodríguez de Mendoza (UNTRM) for developing this diagram. The mentioned station had 15% of missing data, therefore a quality control of the data and multiple imputations was carried out to fill in any missing data. The results obtained show that the winds in this area are mostly weak (from 0 to 3 m/s) with an East-Northeast (ENE) and Northeast (NE) direction for both the studied period and for each year of the period. It has also been determined that there is a difference between the wet and dry seasons in terms of wind frequency. Finally, we conclude that, in the city of Chachapoyas, it is possible to generate wind energy by using low-power vertical axis wind turbines.

The increasing demand for food and energy presents challenges for agricultural and energy sustainability, especially in regions with limited arable land. This study analyzed the productivity and morphological adaptations of Phaseolus vulgaris L. in agrivoltaic systems using monofacial, bifacial, and semi-transparent photovoltaic technologies under the high Andean climatic conditions of Chachapoyas, Amazonas, Peru. The evaluated varieties, Panamito and Chaucha, were cultivated with planting distances of 25 cm and 35 cm. The analyzed variables included plant height, number of trifoliate leaves, number of flowers, number and weight of pods, grain weight, and yield. The experiment was designed with plots under agrivoltaic systems and a conventional system as a control. Environmental parameters such as photosynthetically active radiation (PAR), irradiance, precipitation, leaf moisture, soil moisture, and ambient temperature were monitored. Results showed that the bifacial system with a planting density of 25 cm was the most efficient, recording a plant height of 139.38 cm, an average grain weight of 67.97 g, and a yield of 700.5 kg/ha, significantly surpassing the conventional system. These findings shows the potential of agrivoltaic systems to enhance agricultural production by efficiently utilizing solar radiation and land, providing an innovative solution for integrating agriculture and energy generation, as well as increasing productivity in scenarios with land-use competition and climatic challenges.

The relevance of scientific research to local challenges and the need to produce actionable knowledge that benefits local development have not been evaluated. This study evaluates whether scientific research focused on the Amazonas region is framed within its five regional components of the Concerted Regional Development Plan (CRDP) to achieve sustainable development. In this study, 386 scientific articles published during 1960–2021 focusing on the Amazonas region were evaluated. Although Amazonas is the third poorest region in Peru, scientific production in this region has largely increased (CAGR_2001-2021 = 16.4%). However, women and indigenous authors are underrepresented suggesting a unilateral knowledge transfer. The highest scientific contribution was reported for component 1 of the CRDP (58%), centering on topics about the conservation of biodiversity and ecosystem services. Scientific research focusing on the Amazonas region fails to fully aboard the overall sustainable components of the CRDP. Social sciences are clearly understudied. It is the role of regional institutions (government, universities, industry, non-profit, etc.) to ensure the extension of research topics covering other dimensions of scientific knowledge and social needs. Conclusively, it is pending that local policymakers take into consideration emerging disciplines that can provide an updated perspective in developmental policies in the Amazonas region.

En la actualidad el aprovechamiento de energía de la biomasa es una alternativa para el impulso de matriz energética renovable. Una de las principales fuentes de biomasa son los residuos orgánicos generados por las actividades productivas y cotidianas. Por lo que existen diferentes mecanismos para valorización energéticas como tratamientos biológicos y termoquímicos. Debido a ello, la presente revisión se centra en las tecnologías termoquímicas, en especial en la pirólisis, ya que con este proceso se puede transformar todo tipo de residuos orgánicos, obteniendo productos principales como los bio-aceites, biochares y gases condensables que tienen un alto valor energético, que pueden ser aprovechados en los sistemas de calefacción y generación de electricidad, entre otras aplicaciones. Para obtener cada uno de los productos y aplicaciones dependerá del tipo de pirólisis y el reactor pirolítico. Estos son seleccionados de acuerdo a la composición de la biomasa a procesar. En definitiva, la pirólisis es una tecnología amigable con el medio ambiente debido a que se desarrolla en ausencia de oxígeno y no genera la emisión de gases de efecto invernadero causantes del cambio climático, además que, el biochar, producto de la pirólisis, ha despertado gran interés desde el punto de vista energético y remediación ambiental por la comunidad científica.

Agrivoltaic systems offer a pathway to simultaneously produce food and electricity, yet their effectiveness depends on how photovoltaic configurations influence crop productivity under specific environmental conditions. This study evaluated land-use efficiency in an Andean–Amazon transition region using monofacial, bifacial, and semitransparent photovoltaic configurations integrated with a maize–bean intercrop. Land-use efficiency was quantified through the Land Equivalent Ratio (LER), combining agricultural yield and electrical energy production. All configurations achieved LER values above 1.0, confirming a clear advantage over separate land use. The semitransparent configuration showed the highest LER (1.95–1.99), followed by bifacial (1.66–1.90) and monofacial systems (1.51–1.72). LER variation was driven primarily by crop productivity rather than energy yield, while normalized photovoltaic performance remained stable across configurations. These results demonstrate that agrivoltaic performance is governed by system-level crop response, emphasizing the role of photovoltaic design in optimizing food–energy systems under tropical mountain conditions.
