works on economics

  • Industrial organisation
  • Wine market regulation(self-governance & public policyin the AOC)
  • Local networks organisation
  • diverse reports for:
  • the strategic planning of the research networks for the vineyard of the north-est of France (CRECEP/RVVS)
  • a european project (FORESCENE)
  • first results of a work on the environmental policy in thefrench vineyard

JB Traversac, Cal-Med Meeting - Sonoma, oct 2007

An expertise for a european project FORESCENE : making scenario for the sustainable development of rural areain agriculture

  • Focal issue and area of expertiseA biotechnic and Economic expertise
  • Long terms sustainability goal and targetsThe Renewal of local Agro-Food Systems Network’s
  • Key scenarios elements for a sustainable developementProspective Vines and Wines – Scenarios for Research and actors
  • Key possible instruments and measuresA suggestion

environnemental impacts
Environnemental impacts
  • The pest disease management probleminterogations about the viability of the pest dependant crop systems & healths consequences
  • Viticulture use 50 % of the total weigth of pesticide for 3 % of the crop area(25OOO tons/year)

data colected by the French agricultural departement & the industry union of pesticide producers

consequences
Consequences
  • Health impact : for the producers, numerous studies about relation between use of pesticide (generaly wihtout care) and some severe deseases (e.g. on the children fertility, cancer rate, etc….)
  • Water quality : difficulty to respect the directive EEC 80-778 & the directive cadre on water (2000/60/EC)

The problems are very localised due to the limited wine area

  • Farms sustainability index (IDEA):

structural (AC) & financial survey (RICA)(IDERICA)

Biodiversity: can we conclude with a structural index?

Score on the biodiversity of wine farms

biodiversity in viticultural farms a specific entry
Biodiversity in viticultural farms: a specific entry
  • Random sexual reproduction→ exclusively by wood except for specific program creation of new variety is stoped (resistant variety or new table grappe variety)

low inter ~ 0, but high intra and studies show that - genetic varity in grape is in regression

- association with neighbours species could be rich of insect

  • Quality signal based on variety → 8 major varieties (~ 45% french wineyard )
  • Huge diversity in collection and in different vineyards in almost all EU

sustainable development of agriculture a place for a specific farm census
Sustainable development of agriculture: a place for a specific farm census

IDERICA pertinent index

• edaphic & social index: significativity in question

• economics index: a view of financial performances

  • need of a european agricultural survey in four parts
  • structure (ES): land, workers, crop, cattle, machine,…,
  • activity (EA): with more informations in backward and lateral activities
  • financial results (RICA): with a more detailed and reliable information
  • sustainable developement index (EDD): with edaphic and social index
  • (periodicity of 3 years)

Goals and issues of Sust. Dev.

debates & perspectives

• Discussion about the most efficient method to reduce pest treatmentpollutionpublic prescription vs private certification certification and labelling efficiency

 state efficiency of control of the producers or/and volontary approach

JB Traversac, Cal-Med Meeting - Sonoma, oct 2007

slide20

Would you willing to pay a premium for a Colorado wine,

If it was grown and labeled using sustainable agriculturaland environmentally friendly techniques?

Maria L. Loureiro (2001)

JB Traversac, Cal-Med Meeting - Sonoma, oct 2007

slide21

results on the hedonic prices of SD labels show that it is complicated to associate a SD label to GI (AOC)

    • D. Boughedra, 2004
    • Giraud, 2005 ; Halawany, Giraud, 2007
    • Soler & al., 2007

 efficiency of certification and labelling ~ 0

is the number of participant matter in the effectiveness of environment prescription
Is the number of participant matter in the effectiveness of environment prescription ?

JB Traversac, Cal-Med Meeting - Sonoma, oct 2007

slide27

Main composants of the model

n : number of participant

(constant in a short term)

i’ : level of environmental performance

(voluntary approch requires i < i’)

I : overall level of pollution

(I is a function of several parameters)

(α is the proportion of non participants)

JB Traversac, Cal-Med Meeting - Sonoma, oct 2007

slide28

α is the switching cost from i’ to i

a is the ease of adopting the integrated approach

JB Traversac, Cal-Med Meeting - Sonoma, oct 2007

slide30

To minimise Ithe second order condition has to be positive

JB Traversac, Cal-Med Meeting - Sonoma, oct 2007

slide31

An application for i’=1 (worst score) and a=1 (high inertia to change)

  • REM:
  • for each n, there is 2 sub-optimal solutions
  • i = 0,5 is the optimal solution to optimise I

JB Traversac, Cal-Med Meeting - Sonoma, oct 2007

slide32

Overall environmental performance as a function of required level of pollution per participant and the total number of enterprise (i’=1, a=1)

JB Traversac, Cal-Med Meeting - Sonoma, oct 2007

slide33

Policy implication

  • How to determine the level of resistance to change a?
  • The solution for certain value of i are twice(if there is a cost of negociation C, the administration will preferthe smalest number)
  • An interest group can select a level of i in relation with it’s own interrest(what could be the good reaction to the constitution of such groups?)
