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 and network analysis

Climate change and land-use land-cover changes are altering structure and functioning of forest ecosystems, compromising the ecosystem goods and services they supply. Global change is also disrupting natural disturbances regimes, and the predictions assure that future perturbations will change in frequency, intensity, and extent. Little is known about the feedback effects between changing climate, landscape mosaics, and disturbance regimes yet. Scientists and ecosystem managers concerned with biodiversity conservation and the maintenance of essential ecological functions need to assess the potential consequences of their decisions at different spatio-temporal scales. However, informing the decision making process in a complex and dynamic world is not an easy task. Managers are challenged to address multi-objective decisions for coupled natural and human systems under uncertain climatic, socio-economic, and environmental conditions and shifting natural disturbance regimes.

In this project, I will use a Mediterranean fire-prone landscape and a North American temperate forest ecosystem as examples of socio-ecological systems in which increasingly human interests on land resources will be in conflict with altered natural disturbances regimes. I will investigate the interactions at landscape scale between land-cover changes, forest management, potential disturbance regimes, and vegetation dynamics in a global change context. An evaluation of alternative management options aiming at reduce the negative effects of perturbation on ecosystems while enhancing overall resilience to current and future natural disturbances will be carried out using cutting edge methods. The Mediterranean ecosystem will be modeled by a spatially explicit landscape model integrating vegetation dynamics, natural perturbations, and land-cover change transitions and the underlying interactions. The impact of resilience-based forest management in the temperate ecosystem will be addressed using a plant-functional approach along with a network analysis. The project outcome will be a set of alternative scenarios of multi-objective management options for forest landscapes facing global change, besides a toolbox of a spatially explicit landscape model accounting for the main Mediterranean ecosystems' components and processes and a network-based procedure to evaluate forest resilience.

The Mediterranean


Alt Urgell, Catalonia

In the European Mediterranean basin, fires and land-use land-cover transformations 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 land-cover change model.

The Temperate


Forêt Montmorency, Québec

NNorthern ecosystems show an elevate degree of landscape diversity, regional environmental adaptability, and natural disturbance resilience (mainly wildfires and insect outbreaks). But timber harvesting activities, forest homogenization, farming legacies, and climate warming may alter regeneration potential, growing conditions, and disturbance regimes. In eastern temperate Canada a shift in fire activity, insect outbreaks timing or drought intensity will drive current harvesting practices to be increasingly competing with natural disturbances impacts. The certainty that climate change will directly and indirectly modify insects survival and dispersal capacities, fire susceptibility and drought exposure, constraints forest managers to evaluate alternative strategies in terms of resistance and resilience to perturbations. All these new complex feedback interactions between climate, vegetation dynamics, wildfires, insects, and drought will cause unknown variations on ecosystem functioning.

I will propose alternative forest management options based on plant functional enrichment and species connectivity increasing to cope with multiple natural disturbances. Multi-objective strategies will focus on reducing fire and insect landscape vulnerability and guarantee a long-term functionality. I will use a network analysis approach to quantify the modularity, centrality, and connectivity of functional rich forest patches to evaluate the resilience at the landscape scale.
