Los árboles y el agua
The basis for a better understanding of the evolution of forests (and their management) due to water scarcity.
Description
Water is the protagonist of both hydrological processes (precipitation, interception, evaporation, etc.) and many other fundamental processes: biological (such as photosynthesis), climatic (such as droughts and fires) or soilwise (such as erosion). Furthermore, most of the effects that climate change is having on forests are directly related to hydrological imbalances. Consequently, in order to get to know the state of natural systems and their functioning, it is necessary to analyse the behaviour and relationship of ecosystems in all their processes in relation to this element: water.
In the specific case of forests, carrying out such an analysis involves analysing the arrival, distribution and departure of water in forests; seeing where it is at any given time and how it is used. This means analysing the water involved in the surrounding atmosphere, in the plants that absorb and transpire it, and in the soil that stores and carries it.
Knowing this relationship provides an important information to glimpse the current status of each potential forest and the future possibilities for its evolution:
- The impacts of climate alterations on forests and forest ecosystems: although climate change is unquestionable, its effects on forests are much more diffuse, indirect and unpredictable, and monitoring allows us to detect early symptoms of stress or decline.
- A precise quantification of the state of provision and regulation of key ecosystem services that underpin more dependent ecosystem services (carbon sequestration, growth, baseflow and groundwater supply, water retention and associated wildfire risk, decay and loss of vigour due to water stress, etc.).
- A solid basis on which to justify and base actions to adapt or mitigate our forests to climate change, or improve their resilience.
An increasing number of projects are being carried out to study the relationship between trees and water. It is a subject which creates concern and expectation, also in the Basque Country. For this reason, this course is going to take a closer look at some of them, especially those that focus on tree species typical of the current forests of the Basque Country.
Objectives
Analyse the relationship between forest trees and water: understand how it works and what the key points are.
Detect the problems that climate change, with an increase in droughts and heat waves, may generate in this relationship.
Present current projects where this relationship has been analysed for important tree species in the current forests of the Basque Country.
Activity directed to
- All public
- University student
- Students not from university
- Teachers
- Professionals
- Forest owners and managers; Research and development centres
Methodology
Two days of talks and debates at a basic level. The first day is for analysing the generic concepts of trees and their use of water, and the second day is for analysing specific case studies of this aspect and relating to tree species important in the Basque Country.
Three national speakers on the first day, with a round of questions after each talk (45 minutes of talk and 15 minutes of questions and answers); and a final round table where the subject could be explored in greater depth thanks to the dialogue with and between the speakers. On the second day, four international speakers, with presentations in different languages but translated into Spanish, with a round of questions after each intervention (45 minutes of presentation and 15 minutes of questions and answers). Due to possible translation problems, there will be no round table discussion between these international speakers.
In short, the aim is to analyse both the generic and the specific, based on scientific knowledge.

Speakers

Laura Arnal Roig
Forest Engineer from the Polytechnic University of Valencia and currently pursuing postgraduate studies in Geomatics, Remote Sensing and Spatial Models Applied to Forest Management at the University of Córdoba. She is part of the Re-Forest group in the Department of Hydraulic Engineering and Environment at ETSIAMN (UPV), where she conducts applied research on sensorisation, forest modelling and ecosystem services. She is currently participating in the Interreg Sudoe SocialForest and GREEN BOOST projects of the Biodiversity Foundation, focused on promoting the resilience and adaptation of Mediterranean forests to climate change.

Jesús Julio Camarero Martínez
Research Professor at the Institute of Ecology and Evolutionary Biology (CSIC). His research is aimed at understanding the spatial and temporal patterns and the environmental mechanisms (global change) that control the dynamics (growth, regeneration, mortality) of trees and shrubs from a functional perspective. He has focused his work on understanding the effect of climate variability and changes in land use on processes as diverse as ecotone dynamics (altitudinal and latitudinal limits of the forest) and the effects of drought (decay) on the growth and vigour of forest species. To this end, he has used the study of wood anatomy and dendrochronology. His most recent studies focus on understanding how the components of global change (increased climate variability, droughts, changes in land use) determine processes of mass mortality and forest decline. The ultimate aim of his work is to understand how plant communities of woody species respond to intense disturbances within a broad temporal context defined by the great longevity of many of the species studied, as is the case with trees.

Sylvain Delzon
Sylvain Delzon is a Senior Researcher in Plant Evolutionary Ecology at INRAE - University of Bordeaux, France. He works at the crossroads of plant physiology, quantitative genetics and biogeography. His primary research interest is the understanding of plant ecophysiological responses to environment changes, with a particular emphasis on the mechanisms of drought resistance. He set up the high-throughput phenotyping platform, called CAVIPLACE at INRAE/University of Bordeaux thanks to an EquipEX national grant. This is currently the largest hydraulics platform in the world with a unique prototype developed in association with a local company specialized in industrial mechanics (3 standard cavitrons, one medium cavitron and one megacavitron for long-vesselled species; http://sylvain-delzon.com/caviplace/).

Pello Goikoetxea Urdapilleta
Tolosarra has a degree in economics, business and banking. He is also a forest owner and President of Basoa Fundazioa. Although he is currently retired, he worked for 48 years in the financial sector, participating in the management of both branches and various departments at a corporate level. He started at the Caja de Ahorros y Monte de Piedad de Donostia and, after a stint at the Caja de Ahorros Kutxa Gipuzkoa, ended up at Banco Kutxabank SA. He has accumulated extensive experience in business management as a member of the Purchasing and Investment Committees, board member in the public housing companies of the Basque Government, in the hotel investment companies in which Kutxa has a stake and in several real estate development companies in which Kutxa has a stake. He has also been a member, CEO and President of the ‘Reyes de Aragón’ retirement home owned by Kutxa and a member of the Marketing, Purchasing and Investment committees of Torre Iberdrola, a subsidiary of Kutxabank. He also has experience in volunteering as a Trustee of the Sortek Foundation (business incubator) and President of Santo Tomás Lizeoa (Ikastola de Donostia).

Asier Herrero Méndez
Asier Herrero is an ecologist specialising in the response of forest ecosystems to climatic and biotic stresses. He is currently a doctoral assistant professor in the Department of Plant Biology and Ecology at the University of the Basque Country. His main line of research is the analysis of the vulnerability and resilience of forest ecosystems to disturbances and stress factors associated with climate change. The design and evaluation of management strategies and actions for the adaptation of forests to climate change and the study of the ecological mechanisms underlying species abundance patterns and their coexistence represent his secondary lines of research. His research adopts a multidisciplinary approach including the use of observational data, greenhouse experiments, literature reviews, historical archives of forest management, national forest inventories and ecological models. He has published 23 studies in international journals indexed in the Science Citation Index Expanded, resulting in an h-index of 15.

Frank Krumm
During his doctoral thesis and the years following his doctorate, he focused on subalpine fir forests, analyzing the impacts of land use change, natural disturbances, natural dynamics and the state and management of protection forests. Another central theme in his research, developed in the “InTree” project, has been to review the status of non-native species and their influence on forest ecosystems. The status, development and conservation potential of nature (biodiversity) in managed forests has become the main focus of the last 10 years of his professional career. Above all, he has focused on integrated forest management (how to integrate the different forest functions in forestry and, at the same time, promote biodiversity conservation). Finding and offering options and solutions for practical forest management is currently his main motivation. Current projects focus on the complete timber value chain, balancing CO2 emissions to reach net zero while maintaining other ecosystem services.
