Sozio-ökonomische Auswirkungen einer Jatropha-Plantage auf ländliche Haushalte und deren Gemeinden in Madagaskar

Project begin: 01.07.2012

Project end: 30.04.2017

Sponsor mark: A 298 12

Das Forschungsvorhaben führt die von 2008 bis 2011 durchgeführte Analyse der sozio-ökonomischen Auswirkungen einer Jatropha-Plantage in Madagakar fort. Ziel ist eine umfassende Bewertung der direkten und indirekten Auswirkungen der Plantage auf die sozio-ökonomische Situation der umliegenden Dörfer und deren Bevölkerung. Dafür wird aufbauend auf den vorangegangenen Haushaltsbefragungen ein umfangreicher Paneldatensatz entstehen, der auf Basis einer ökonometrischen Analyse Aussagen zur Nachhaltigkeit der bisher nachgewiesenen positiven Effekte sowie erst mittelfristiger erwartbarer und indirekter Auswirkungen erlaubt.

Angesichts negativer Schlagzeilen, die steigende Ernährungsunsicherheit auf großflächige Energieproduktion zurückführen, sollen die Ergebnisse Aufschluss über Zusammenhänge geben und politische wie privatwirtschaftliche Entscheidungsträger über soziale Nachhaltigkeit sowie gesellschaftlicher Realisierbarkeit von Bioenergieprojekten auf marginalen Flächen informieren.
