Abstract:
Rural-urban migration of male labour force is an unstoppable process in China. Although some women also migrate to work in cities, most of these women return to the villages after marriage. They need to take care of the children and the family and to work on their smallholder farms. In general, women‟s labour participation in agriculture has increased due to the migration of the male labourers and they have become the main labour force in smallholder agriculture. This thesis is a sociological analysis on the impact of this change on the situation of these women and on smallholder agriculture from the women‟s perspective.

Abstract:
De visie van de biologische landbouw op duurzaamheid is verwoord door IFOAM in hun doelstelling en in de 4 beginselen van de biologische landbouw en is vertaald in diverse praktische regels voor biologische productie. In dit proefschrift noemen we deze visie het biologisch-ethisch kader. De hoofddoelstelling van dit proefschrift was het vaststellen van het effect van dit biologisch-ethisch kader op de integrale milieubelasting van biologische eierproductie in Nederland. Deze doelstelling werd benaderd vanuit 3 invalshoeken: 1) het vaststellen van het verschil in integrale milieubelasting van eierproductie met en zonder het biologisch-ethisch kader, 2) het identificeren van de belangrijkste milieuproblemen in het bestaande biologische eierproductiesysteem in Nederland en 3) het verkennen van mogelijkheden om de integrale milieubelasting van Nederlandse biologische eierproductie te verbeteren binnen de grenzen van het biologisch-ethisch kader.
