The organic resources (OR) system

The wide diversity of organic ressources and stakeholders

• OR : manure, food wastes, crop residues, digestate, urban sludges

• Stakeholders : farmers, biomass plants, waste water treatment facilities, agro-food industries, compost platforms

R. Misslinet al. ISEM, 1-5 oct. 2019, Salzburg MAELIA-ORM 1

Optimization of organic resources (OR) territorial management

Use of organic resources has multiple impacts on the territory

• Environmental : soil health soil structure ecosystem services

• Economical : economic performance of farms, territorial economy organization

• Social : farmers’ work load, social networks

OR management : a multi-level challenge

• Field : fertilization strategies, cropping system × available OR

• Farm : OR management by farmers (e.g. application work load)

• Individual OR chain : production transformation consumption

• Territory : collective optimization of OR management and impacts

 How to optimize OR chains taking into account the specifities of each chain and farm and the objectives regarding their effects?

The social-ecological system perspective

What tool for modelling and simulating OR management?

MAELIA : a agent-based model that simulates agricultural territories for the integrated assesment (multi-criteria – multi-level) of the management of natural resources (inclunding ecosystem services)

Individual dynamics of plots and farmers (based on decision rules) :

Spatial data inputs : structure of the social-ecological system

MAELIA-ORM : a multi-scale

modelling tool for territorial

organic resources management

(ORM )

(8)

Field scale : evaluate / enhance organic products effects

Farm scale : decision rules for OR management

Farm scale : decision rules for OR management

Chain scale : production, transformation, consumption

Organic resources chain characteristics

• Simulate biomass flows

• Simulate the OR market (taking into account costs & distances)

• Transformation units use recipes and order/sell products

• Transformation dedicated algorithms (e.g. methanation) Example : the composting chain

R. Misslinet al. ISEM, 1-5 oct. 2019, Salzburg MAELIA-ORM 9

(12)

Territorial scale : scenarios assessment

Implement governance scenarios

• Farmer aids

• Changes in institutional constraints

• Transformation unit construction

• Climate change

Territorial simulations

Evaluate effects with indicators

• GHG emissions

• Economical performances

• Ecosystem services

• Sustainability

R. Misslinet al. ISEM, 1-5 oct. 2019, Salzburg MAELIA-ORM 10

PROTERR project : MAELIA-ORM tested on 3 territories

Coglais

• livestock farming

• Maize, wheat &

grasslands

• Biomass plant project

Plaine de Versailles

• Wheat & rapeseed

• Urban sludges

• OR from the netherlands (beetpulp residues)

Pays Rhin-Vign.-G.B.

• Maize monoculture

• Low OR avaibility, Little livestock

• Biomass plant projects
