The potential impact of agroenergy on sustainability. The case study
University of Pisa – Department of Agriculture, Food and Environment
Background The European energy strategy towards 2020 builds on a set of
binding Community-wide targets, with the explicit purposes of reducing dependence on imported fossil fuels and boosting new energy technologies
In Italy, farm-based biogas installations have recently boomed. The public support system, “green certificates” diversifying the production could help stabilise incomes three interdependent global crises at the energy, environmental and
agricultural level may have contributed to biogas success (Carrosio, 2013).
Geopolitical trends, with rising political and social instability in fossil fuel-producer countries and the emergence of state-owned energy champions had a relevant role in the global increase of traditional fuels prices until 2008 (Umbach, 2010).

"green certificates" confonde: - si applicavano solo sopra una soglia di produzione- la normativa è cambiata- tuttavia, indubbio contributo della vecchia normativa alla costituzione del settore
Objective of the paper to deliver an analysis of the impact of the diffusion of
biogas installations at the territorial level, To take the Italian province of Pisa (NUTS 3) as a case
study
University of Pisa – Department of Agriculture, Food and Environment
Methodology we simulate farmers’ behaviour facing a decision over the
adoption of a farm-scale biogas plant, to assess decisions’ impact at the territorial level by applying a three-step methodology.
(i) representative farms; (ii) simulation of farmers’ behaviour; (iii) impact assessment at farm level & at territorial level
University of Pisa – Department of Agriculture, Food and Environment
Methodology (Representative farms) Model applied at farm level Representative farms results for a non-hierarchical
cluster analysis across the province of Pisa clustering Variables are: farm size; labour used; amount
of SFP received Farm profiles result from value averaging at the cluster
level

Methodology (simualtion of farmers’ behaviours) simplified version of the farm-household model Dynamic model (mixed-integer non linear model)

Simulation of 5 alternative methane digesters Diversified by installed power (from 108 to 972 kW/h),
for the investment costs, for the annual maintenance costs and for the labour requirements
Methodology (impact assessment) A set of indicators is measured at the cluster level Impact upscaling at the territorial level results from the comparison of the
weighted sum of clusters' performances with area clusters' weights Economical
NPV Reliance on paymment (SFP/NPV)
Social plant installed power kW/h dedicated crops demand for biogas production (i.e.silage maize) labour force employed in the agricultural sector

Data Micro-data from 2010 Italian Census of Agriculture 1852 farms located in the province of Pisa (UAA>1ha):
arable, vegetable, livestock no biogas plants are currently operating 18 farm profiles (from cluster analysis)
