    Unprecedented is the number of international efforts by governments and private actors alike that seek to foster sustainable landscapes around the globe for the wellbeing of humans and nature. Working towards achieving the Sustainable Development Goals, the Bonn Challenge, the New York Declaration on Forests, the Aichi Targets of the CBD, the Paris Agreement, or regional efforts like the African Agenda 2063, the Global Landscapes Forum in Bonn 2018 aims to accelerate and mobilize collective action on the ground.

    大约三年前,各国领导人就联合国《2030可持续发展议程》及其17个可持续发展目标达成一致,自此该议程和目标成为指导全球发展政策的核心框架。本版《世界森林状况》旨在加强我们对森林及其可持续经营如何为实现多项可持续发展目标做出贡献的理解。对世界森林而言,时间紧迫:我们必须开展跨部门协作,把利益相关方集合起来,尽快采取行动。《2018年世界森林状况》确定了可采取的行动,以增强森林和树木为加快实现可持续发展目标所必需做出的贡献。现在必须采取措施以更有效地与私有部门合作,必须对非正规部门进行改革,以实现更广泛的经济、社会和环境效益。七十年前,当联合国粮农组织完成其第一次世界森林资源评估的时候,主要关注在于是否有足够的木材来满足全球需求;而现在,我们则认识到森林和树木具有更为显著的全球意义。《2018年世界森林状况》第一次就森林和树木对景观和生计的贡献进行了评估。本报告目的是让更多读者了解森林和树木对人类、地球和子孙后代的重大意义。

    Why is it so important to restore degraded landscapes? It’s actually very simple.
    We rely on healthy ecosystems to provide us with our food, water, clean air, climate stability, social and economic wealth; even our happiness and well-being. We only have to look at history to see the devastating consequences of not valuing or understanding ecosystems: whole civilizations have vanished after overexploiting their natural resources.

    La importancia de los incendios forestales en la cuenca mediterránea hace de estas perturbaciones un factor determinante en el análisis y la gestión de riesgos ecológicos, así como en los vinculados a la protección civil. La actual demanda de servicios recreativos en el bosque genera una intensificación de estos riesgos, lo que precisa de una adecuada respuesta por todos los agentes implicados en la gestión.

    En el presente trabajo se analiza cómo afecta la composición y estructura del bosque a la riqueza de aves forestales, a escala de 1x1 km, en Cataluña. Se muestra que la riqueza de aves se ve favorecida por la cabida forestal, siempre que se evite la dominancia de masas excesivamente cerradas (FCC [Fracción de Cabida Cubierta] 70%); por la presencia de las clases naturales de edad más avanzadas (latizales y fustales); y por la diversidad de especies arbóreas y la mezcla de frondosas y coníferas.

    Land Use Policy Volume 59

    Peer-reviewed publication
    December, 2016
    Brazil, Trinidad and Tobago, United States of America

    We propose a causal analysis framework to increase understanding of land-use change (LUC) and the reliability of LUC models. This health-sciences-inspired framework can be applied to determine probable causes of LUC in the context of bioenergy. Calculations of net greenhouse gas (GHG) emissions for LUC associated with biofuel production are critical in determining whether a fuel qualifies as a biofuel or advanced biofuel category under regional (EU), national (US, UK), and state (California) regulations.
