- Controlador de luz e temperatura para a criação de canáriosPublication . Moreira, Francisco; Teixeira, João PauloO trabalho faz parte do desenvolvimento de um controlador de luz que permite simular o amanhecer e anoitecer às horas definidas pelo utilizador e, simultaneamente, controlar a temperatura. O equipamento tem como objetivo ser utilizado para criadouros de aves em que o período reprodutivo pode ser controlado pelo número de horas de luz. O controlo de todo o sistema é efetuado através do microcontrolador ATMEGA328P da Atmel, juntamente com o RTC (Real Time Clock) DS1307+ da Maxim. O controlo da simulação do amanhecer e anoitecer é efetuado através de PWM (Pulse Width Modulation) e o controlo da temperatura através de um relé. O sistema possui também um ecrã LCD onde são fornecidas todas as informações necessárias ao utilizador, tais como, data, hora, temperatura, e permite ao utilizador configurar todo o equipamento por meio de 4 botões. O equipamento tem a capacidade de efetuar dois ciclos distintos, podendo o utilizador optar por utilizar apenas um, ou os dois ciclos. O utilizador pode também definir o início dos ciclos no intervalo diário de 24 horas, pode definir a temperatura alvo do criadouro, pode definir a duração dos ciclos, e pode, caso seja necessário, ajustar as horas do relógio do equipamento. O equipamento encontra-se concluído, e encontra-se apto para ser introduzido num ambiente real.
- Stakeholder perceptions of wildfire management strategies as nature-based solutions in two Iberian biosphere reservesPublication . Lecina-Diaz, Judit; Campos, João C.; Pais, Silvana; Carvalho-Santos, Cláudia; Azevedo, João; Fernandes, Paulo M.; Gonçalves, João Francisco; Aquilué, Núria; Roces-Díaz, José V.; Torre, María Agrelo de la; Brotons, Lluís; Chas-Amil, María-Luisa; Lomba, Angela; Duane, Andrea; Moreira, Francisco; Touza, Julia M.; Hermoso, Virgilio; Sil, Ângelo Filipe; Vicente, Joana R.; Honrado, João P.; Regos, AdriánIncreased large and high-intensity wildfires cause large socioeconomic and ecological impacts, which demand improved landscape management approaches in which both ecological and societal dimensions are integrated. Engaging society in fire management requires a better understanding of stakeholder perceptions of wildfires and landscape management. We analyze stakeholder perceptions about wildfire-landscape interactions in abandoned rural landscapes of southern Europe, and how fire and the land should be managed to reduce wildfire hazard and ensure the long-term supply of ecosystem services in these fire-prone regions. To do so, a structured online questionnaire was sent to the stakeholders of two transboundary biosphere reserves in Spain-Portugal. Our analysis also questioned to what extent fuel management strategies can be considered nature-based solutions (NbS) using the IUCN standard. Overall, stakeholders state that fire should be managed and support fire prevention in lieu of fire suppression policies. Rural abandonment is perceived as the main cause of large wildfires, with high-intensity fires impacting the study regions more than in the recent past, a trend which they expect to continue in the future in the absence of management. All the suggested fuel management strategies, except chemical treatments, were accepted by the stakeholders who perceive more positive than negative effects of fuel management on forest ecosystem services. Transboundary coordination was rated as inadequate or even nonexistent. We did not find differences among stakeholder sectors and biosphere reserves, indicating that in the study area, there is a general agreement on perceptions about wildfire and associated impacts at the landscape level. Finally, we showed that promoting agricultural and livestock uses, modifying forest species composition to increase fire resistance, and introducing large herbivores have the potential to become effective NbS in the regions. This study represents a first-step analysis representing a base for future co-design and implementation of NbS to improve fuel management, contributing to the understanding of the stakeholder support for their application in addressing the socioeconomic challenges in high fire-risk areas.
