Research project

In a nutshell:
Investigate interactions between vegetation dynamics, natural disturbances, and land management options in a global change context using spatially explicit landscape dynamic models

Climatic warming and land-use change are altering structure and functioning of ecosystems, compromising ecosystem goods and services supply. Scientists and ecosystem managers concerned with the maintenance of essential ecological functions and biodiversity conservation need to assess the potential consequences of their decisions at different spatio-temporal scales. Sustainable development management in the face of global change means planning for both present and future needs while recognizing climatic, socio-economic, and environmental uncertain conditions. As climate change will alter current patterns of fire frequency and intensity, sustainable forest management will be specially challenging in fire-prone landscapes but susceptible to other natural disturbances too, whose future compounded dynamics will be hardly predictable.

Managers are challenged to address multi-objective decisions for complex social-ecological systems under shifting natural disturbance regimes. However, guiding the decision making process in a complex and dynamic world is not an easy task. In this project, I will use the Mediterranean and the Boreal ecosystems as examples of socio-ecological systems in which increasingly human interests on land resources will be in conflict with altered fires regimes. For these two fire-prone ecosystems, I will investigate the interactions at landscape scale between land-use changes, forest management, fire regime, and vegetation dynamics in a climate change context. An assessment of alternative management options aiming at reduce the negative effects of fires on ecosystems while enhancing overall resilience to current and future natural disturbances will be carried out using spatially explicit landscape models integrating vegetation dynamics, natural perturbations, land-use change transitions, and forest management. The project outcome will be a set of alternative scenarios assessments of multi-objective management options for fire-prone landscapes facing global change, besides a toolbox of spatially explicit landscape models accounting for the main Mediterranean and Boreal ecosystems' components and processes.

The Mediterranean


Alt Urgell, Catalonia

In the European Mediterranean basin, fires and land-use changes have historically shaped terrestrial ecosystems leading to heterogeneous fragmented landscape mosaics. Current continuous vegetation-cover matrixes, the spreading of vulnerable wildland-urban interface areas, and increasing available fuel-load in forests have arisen from more recent and acute processes: rural abandonment, downturn of active forest management, urban sprawl, and fire policies promoting total extinction and less prevention. The scientific and social communities are still debating the effects of high fire suppression rates on fuel accumulation and their consequences on fire hazard, being even more challenging when considered over large managed landscapes under climate change conditions.

I aim at investigating alternative measures in a highly humanized Mediterranean landscape prone to fire by studying the spatial interactions between natural- and human- induced disturbances under future climatic and socio-economic conditions. I will evaluate the effects on fire regime and forest structure when combining fire suppression strategies and fuel management under different climatic scenarios. I will couple two spatially explicit landscape dynamic model to investigate the interacting processes modulating Mediterranean regions: the MEDFIRE, a fire-succession model, and the MEDLUC, a land-use model.

The Boreal


Forêt Montmorency, Québec

Northern ecosystems show an elevate degree of landscape diversity, regional environmental adaptability, and natural disturbance resilience (mainly wildfires and insect outbreaks). But harvesting activities, fire suppression legacies, and climate warming may alter regeneration potential, growing conditions, and disturbance regimes. Even though in eastern boreal Canada fire predictions lead future burn rates to get closer to the upper boundaries of the natural range of variability, a rise in fire activity will drive current harvesting practices to be increasingly competing with fire. The certainty that climate change will impact directly and indirectly on insects survival and dispersal capacities, constraints boreal forest managers to evaluate alternative strategies in terms of resistance to insect attacks. All these new complex feedback interactions between climate, vegetation dynamics, wildfires, and insects will cause unknown variations on long-term carbon carrying capacity of boreal forests.

I aim at assessing alternative forest management options based on the TRIADE approach. Multi-objective strategies will focus on reducing fire and insect landscape vulnerability and guarantee a long-term net ecosystem carbon balance close to zero. I will use the spatially explicit forest model VLM that reproduces the main natural- and human- induced ecosystem processes in boreal landscapes, and the Carbon Budget Model of the Canadian Forest Sector (CBM-CFS3) to investigate the effects of wildfires and management activities on the carbon balance.
