Need of a framework for creating sustainabilityscenarios integrating different environmental topics(water, soil, resource use etc.)

Need for access to scenarios that can be used forstrategic policy preparation in the context of theSustainable Development Strategy.

Need to understand the key driving forces and theircross-cutting linkages, which lead to increasedpressure on the environment.

Initial points

FORESCENE is developping an analytical frameworkfor consistent environmental sustainabilityscenario building (forecasting, backcasting,simulation) in areas such as water, soil,biodiversity, waste and natural resources.

There is a focus on backcasting, to identify differentscenarios leading to the achievement of future targets.

Objectives

Page 6: The FORESCENE project: Developing scenarios and modelling for sustainability

WI, CEM, LUCSUS Brussels Nov. 08

•describe the chosen environmental problems,review policy objectives and indicators, anddetermine the cross-cutting driving forces;

•develop core elements of integrated sustainabilityscenarios (goal definition);

•determine cross-sectoral measures andprocesses to be considered for change (pre-backcasting);

•address quantitative and qualitative parametersfor measurement (parametrization);

•develop a Business-As-Usual (BAU) scenarioframework and example projections(forecasting);

•develop alternative scenarios (incl.backcasting);

•check the options for modelling, and

•work out conclusions.

Structure of the FORESCENE Meta Model

Page 22: The FORESCENE project: Developing scenarios and modelling for sustainability

Important:

The Bayesian network approach is not seen in FORESCENE as areplacement of other models in current use but rather as a meansof integrating different forms of knowledge, whether from existingmodels, reported data or expert judgement.

In other words, the Bayesian network approach is used toconstruct a meta-model.

Disclaimer

• Inputs (drivers, strategies) are considered at EU level

• Outputs (environmental impacts associated with EU) are consideredat world level (except for water)

Bayesian networks do not allow for intrinsic modelling of time dynamics ina satisfactory way.

Question 5: What happens with BAU ?

Page 34: The FORESCENE project: Developing scenarios and modelling for sustainability

WI, CEM, LUCSUS Brussels Nov. 08

Initial conditions

- Initial year is 2000 (or 2005 in when data available)- Initial values are directly taken or estimated from reported or

modelled data (e.g. Eurostat), or derived from expert judgement

Assumptions for forecasting:

- Time frame: 2000-2050- Assumptions for growth rates are directly taken or estimated

from existing studies and models (e.g. EEA environmentoutlook)

Uncertainties

- They are implemented as normal distributions- For example: when two different sources give the values x and y

for a given variable A, the representation of A in the BN can be anormal distribution with mean = (x+y)/2 and 90% CI = |x-y|/2

Alternative scenarios

AS1,Commitment tochange

Under this scenario there is clear commitment tothe goals of sustainability. There are markedimprove-ments in the efficiencies of using energy,materials and water, and there is expan-sion inrenewable energy production. The rate of change ismoderate to high and significant improvementshave mostly been achieved by 2030. …..

AS2, Muddlingthrough

Under this scenario some of the sustainability goalsidentified are achieved in the medium term, butsuccess is patchy and modest.……

AS3, Failing todeliver

Under this scenario the transition to sustainabilityhas been unsuccessful or weak. Increasedconsumption of resource intensive goods hasmeant that there has been less progress towardshigher energy and resource efficiency…..

Reduction of TMR reduces domestic and foreign wastegeneration

Environmental burden shifting is reduced:- no land use change/pressure on biodiverstiy in otherregions due to biofuels- reduced foreign TMR/mining waste

Water consumption tends to decline due to- reduced cooling water demand energy supply- reduced material use in manufacturing

Improved biodiversity due to mitigated GHGemissions (and additional measures)

Synergistic effects of modelledstrategies
