  2. 1. From Betterment to Bt maize : agricultural development and the introduction of genetically modified maize to South African smallholders

    Author : Klara Fischer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Agriculture has received renewed attention in poverty reduction efforts in Africa in recent years, and there are hopes that GM crops could have an important role in helping increase smallholder yields and reduce poverty. Drawing on critical discourse analysis (CDA) and livelihoods perspectives, this thesis examines the ideas governing the Massive Food Production Programme (MFPP), an agricultural development programme aiming to reduce poverty by raising agricultural production in Eastern Cape Province, South Africa, and its local effects when implemented in smallholder communities.

    Abstract : As part of a bio-based economy, biorefineries are envisaged to sustainably produce platform chemicals via biochemical conversion of agricultural and forestry residues. However, supply risks, the recalcitrance of lignocellulosic biomass, and inhibitor formation during pre­treatment impair the economic feasibility of such biorefineries. READ MORE
