Research topics in agricultural and resource economics mainly cover agricultural and trade policy, environmental economics and policy, and development economics and policy. To study these three thematic fields, theoretical and applied modeling tools are designed and developed using a microeconomic approach
Optimization and econometric models are developed for evaluating agricultural, environmental and trade policies at the farm, household, regional and national levels. Costs functions are estimated to measure gains in farm productivity. Determinants of farm household incomes and expenditures are econometrically identified. Price transmissions from the world market to local markets are assessed

We specialize in four related approaches to development problems. The first approach is the analysis of poverty, its dynamics and its causes, of coping strategies, of the agricultural household and of commercialization. The second approach covers market development, the informal sector, norms and institutions. The third approach aims at understanding land use, land markets (or agrarian relationships) and land conflicts. The fourth approach tackles governance issues, from local collective actions to international aid.

Impact assessments of public policies and industrial strategies are designed and conducted in the following domains: circular economy, material and grey field recycling, non-energy extractive industry, water industry, and freight transport.
Leader: Ignace Adant
Our group focuses especially on three kinds of modeling. Game theory and collective choice theory provide a theoretical background for voting problems, applied public economics, industrial organization and in particular spatial competition frameworks. In applied micro-econometrics, we specialize in qualitative variables, panel data and big database management. Finally, our fields of interests include optimization model and computable general equilibrium.

Development and analyses of innovative agricultural systems are performed on several crop systems (buckwheat, oilseed rape, pear; A.-L. Jacquemart). We question the improvement of pollination services using AES (agro-environmental schemes) methods such as managed flowering strips or hedgerows.

Increased temperature regimes and water stress are linked to global climate changes. We analyse the effects of these abiotic stresses on plant flowering and reproductive system (A.-L. Jacquemart). We are particularly aware about the influences of modified floral biology (morphology and phenology) as well as floral resource availability on plant-pollinator interactions. Such interactions are crucial for plant reproductive success and plant yield.

Crop production or wild species survival depends on reproductive success. From floral biology (including morphology, pollen and nectar quantities and composition …) to hand-pollination and mating system estimation, our research projects are focused on plant pollination and reproduction.

Plants genetics and diversity
Crop breeding provides and maintains genetic diversity that constitutes new opportunities as well as an insurance for future adaptations in crop species (P. Bertin). Genetic diversity, structure and gene flow are determinant elements for wild species management and conservation. Clonal structure, genetic diversity conservation, outcrossing rate and gene dispersal offer opportunities for recommendation in wild population conservation and in invasion risk assessment (land planning, nature reserves; A.-L. Jacquemart)
- Heathlands (T. Albert)
- Alien species in Belgium (M. Pairon)
- Survival of rare species (L. Somme)
Pollination, insects and reproduction
We are studying pollination since 1988. Pollination remains the first step for the reproductive success of the majority of seed plants. Plants require pollinators to transfer pollen from the anthers to the stigmas. Pollinators (insects) require plants for food resources (pollen and/or nectar). Plant-insect interactions are usually considered as evolutionary stable strategies (ESS). Floral biology provides data about resource quantity, availability and composition. Pollinator observations determine insect species necessary and efficient in pollination. Insect behaviour and learning (bumblebees) questions patterns in plant-insect interaction evolution. Self-compatibility and inbreeding depression estimations require hand-pollinations. The reproductive success of any plant species is thus estimated and recommendations for species conservation (both plant and insect) are considered (A.-L. Jacquemart).
- Bog and heatlands conservation (L. Moquet)
- Improvment of pear production (M. Quinet)
- Decline of pollinators (L. Somme)
- Alien impact (A. Vervoort)
- Survival of rare species (L. Somme)
Methods and concepts in pollination and reproduction are applied to crop species (see above) and wild species. In wild species, conservation of plant and insect interactions in food networks offers windows for recommendations about nature reserve planning such as connectivity, size of the remnant fragments, density and diversity of flowering plants within fragments … On the other hand, the same methods provide future predictions and advices to alert for potential risk of invasion in exotic species. Several invasive species have been studied (Prunus serotine, Senecio inaequidens, Impatiens spp., ..)
- Survival of rare species (L. Somme, C. Mayer)
- Bog and heathland conservation (L. Moquet)
- Alien impacts (V. Cawoy)
- Cheaters in pollination (L. Bruyère)
