Estimación de los costes de inventario forestal con y sin información LIDAR

Las aplicaciones tecnológicas obtenidas a partir de sensores láser aerotransportados (Airborne Laser Scanner, ALS), han supuesto una gran expectativa para mejorar la calidad de los datos del inventario forestal, mediante su actualización y la posible disminución de los costes de inventario. Sin embargo, todavía existen problemas de aplicación que no están resueltos de manera que su empleo como sustitutivo de un inventario tradicional presenta algunas incógnitas, tanto de carácter técnico como económicas. Por ello, en este trabajo se va a realizar un estudio analítico de costes de utilización, teniendo en cuenta los objetivos del inventario y las limitaciones de la técnica. El caso de estudio se sitúa en el Pinar de Valsaín (Segovia)

Basis on rhizoculture: management of ¿underground agroforestry systems ¿to improve their climate change resilience

Agroforestry has traditionally been focused on the most economically valuable elements of plants. However, Horizon 2020 Societal Challenge analyses indicate that new nature-based solutions that include the multiple functions of ecosystems are needed for the transition towards a circular economic eco-innovation system to change production and consumption patterns towards a green society. In agroforestry, a better understanding of soil and organism interactions with host plants would allow an intensification on the development and activity of their roots leading to increased resistance of plants to climate change and soil C sequestration and to decreased fertilization dependence. The development of this multidisciplinary body of knowledge could be called ?rhizoculture?. The present work propose a review and a research project to develop a new "rhizoculture" approach in Agroforestry connecting the root, rhizosphere, agroforestry uses, fertilizier managements and landscape planning, all supported by 4 research approaches: (1) agrotechnological support to root development, (2) biological and biogeochemical support to "soft" fertilization and rhizosphere management, and (3) soil organism management by soil organic matter control (by extensive livestock and biomass uses) and other tools, (4) landscape planning using territorial analysis tools, as i.e., Openforis Collect Earth. Seeking to change production and consumption patterns towards a sustainable, green economy and society, the benefits associated to this type of research on rhizoculture may increase the biodiversity and C stock in the soil, moreover, the development of the roots in agroforestry systems would increased the plant¿s ability to cope with environmental and climatic changes. This approach would also improve the health and performance of plants and decreased the high costs and pollution associated to fertilizers and phytochemicals
