Autoria: PENEDO, T. S. de A.; AGOSTINI, K.; RECH, A. R.; SARAIVA, A. M.; VIANA, B. F.; JOLY, C. A.; BOSCOLO, D.; VARASSIN, I. G.; SALIM, J. A.; HIPÓLITO, J.; MAUES, M. M.; WOLOWSKI, M.; GHILARDI-LOPES, N. P.; MARINI-FILHO, O. J.; BERGAMO, P. J.; MARUYAMA, P. K.; FREITAS, L. Conteúdo: Brazil’s recent environmental licensing reform exposes a contradiction between national regulation and international climate and biodiversity commitments. Law No. 15.190/2025 narrows analytical scope, expands exemptions, weakens preventive mechanisms, and shifts responsibilities to subnational authorities with uneven technical capacity. Although environmental impact assessments remain formally required, the law reduces their applicability and overlooks indirect, cumulative, and synergistic impacts. It also omits ecosystem services, despite scientific consensus on their role in climate regulation, water provision, soil protection, and pollination. This omission underestimates socio-environmental risks and undermines resilience, food security, and long-term planning. This contradiction is evident in Brazil’s renewed international engagement, including its role as host of the 30th United Nations Climate Change Conference (COP30) in Belém. To align national regulation with global commitments, integrating ecosystem services into licensing, alongside transparency and impact data disclosure, is urgently needed. 2026-01-01T00:00:00Z https://www.alice.cnptia.embrapa.br/alice/handle/doc/1188401 Título: Optimizing irrigation strategies in black pepper (Piper nigrum L.) for enhanced productivity and essential oil yield. Autoria: MARTINS, J. dos S.; LIMA JUNIOR, J. A. de; LEMOS, O. F. de; GOMES, M. D. de A.; SANTOS, H. C. A.; GONÇALVES, M. A. de S.; CAMPALLE, A. N.; MARTINS, H. L.; PARREIRA, M. C. Conteúdo: Black pepper (Piper nigrum L.) is an important crop in Pará, Brazil; however, irrigation management remains one of the main constraints to achieving stable productivity and high essential oil yield. By determining soil water tension for rational irrigation management that ensures high agronomic performance of black pepper, it is possible to optimize irrigation water use efficiency through monitoring critical soil moisture with the aid of tensiometers. This study evaluated yield, water use efficiency (WUE) and essential oil yield of two black pepper genotypes under five soil water tensions (15–55 kPa) using a split-plot experimental design. The Uthirankotta genotype showed higher yield and WUE, reaching maximum values at 35 kPa, whereas the highest essential oil extraction yield occurred at 15 kPa. Positive correlations were observed between essential oil yield and the main productive traits. Therefore, cultivation of the Uthirankotta genotype under tensiometer-based irrigation management is recommended under the edaphoclimatic conditions of Pará, using a critical tension of 35 kPa as a reference to increase productivity and optimize irrigation water use efficiency, considering the differential genotype response to irrigation management under humid tropical conditions. 2026-01-01T00:00:00Z https://www.alice.cnptia.embrapa.br/alice/handle/doc/1188396 Título: Welfare indicators in cattle farming in the face of heat stress: a review in climate change scenarios. Autoria: SOUZA, I. M. F. de; SOUSA, C. E. L.; PINTO, V. S.; VILELA, L. G. P.; SOUZA, A. da S.; CUNHA, J. P. de S.; ARAÚJO, C. V. de; GOMES, M. de N. B.; SILVA, L. K. X.; MARTORANO, L. G.; NEVES, K. A. L.; CAMARGO-JÚNIOR, R. N. C.; SILVA, É. B. R. da; SILVA, W. C. da Conteúdo: This work consists of a narrative review that addresses the differences between European cattle and Zebu cattle in their resilience to environmental challenges. It was developed based on scientific articles, theses, dissertations, and technical documents available in recognized databases such as Web of Science, ScienceDirect, Scopus, and PubMed, prioritizing recent studies from 2020 to 2025 that are relevant to the topic. The method used was a narrative review, in which publications addressing the physiological, behavioral, bioclimatic, and adaptive production parameters of each animal group were selected, allowing for a comparative analysis of their main characteristics. The results indicate that European cattle, although highly productive, are less adapted to heat, while zebu cattle stand out for their hardiness, resistance to high temperatures, and lower incidence of diseases. The conclusion is that analyzing these differences is essential to guide breed selection, genetic improvement strategies, and the adoption of more sustainable production systems, favoring greater livestock efficiency and resilience under diverse environmental conditions. 2026-01-01T00:00:00Z https://www.alice.cnptia.embrapa.br/alice/handle/doc/1188402 Título: “Aqui em casa todo mundo tem terra, se quiserem podem plantar”. Autoria: RIBEIRO, L. B.; MOTA, D. M. da; MOREIRA, É. da C. Conteúdo: O objetivo deste artigo é analisar evidências recentes de reprodução social de trabalhadores rurais no pós-trabalho assalariado na dendeicultura na vila rural de Belenzinho, Acará (PA), no Nordeste Paraense. A pesquisa foi realizada por meio de um estudo de caso na vila rural de Belenzinho no município do Acará, no nordeste paraense no período entre 2021 e 2023. Privilegiamos a observação direta, o registro de conversas informais e entrevistas por meio de questionários semiestruturados com 18 trabalhadores que vivenciavam o pós-trabalho assalariado na dendeicultura. As principais conclusões mostram que esses trabalhadores rurais, ao se desligarem do assalariamento, têm sua reprodução social vinculada à agricultura por meio da produção de culturas alimentares e comerciais ligadas, respectivamente, à tradição e às recentes exigências de mercados globais: mandioca, açaí e dendê. Relações de trabalho entrelaçam-se com o trabalho familiar em terras próprias e arrendadas para garantir alimento, renda e permanência nos lugares de origem. 2025-01-01T00:00:00Z
