Climate change threatens agricultural productivity worldwide, resulting in higher food prices. Associated economic gains and losses differ not only by region but also between producers and consumers and are affected by market dynamics. On the basis of an impact modeling chain, starting with 19 different climate projections that drive plant biophysical process simulations and ending with agro-ec...

The cereal, oilseeds, and protein crop sector (COP) occupies a prominent position within the European Union’s agricultural sector. Within Spain, the COP sector accounts for almost a third of total Agricultural Guidance and Guarantee Fund expenses, and a half of the utilized agricultural area. The COP sector is not only relevant because of its physical and economic magnitude, but also because of...

Voluntary sustainability standards (VSSs) in global production networks (GPNs) have grown significantly prominence. Existing research largely assumed that VSSs create linear upgrading outcomes for all GPN actors and has studied from the point of adoption GPNs, rather than a broader range stages their lifecycle. To address these limitations, building on literature around power agency we develop ...

The use of agricultural-based biofuels has expanded. Discussions on how to assess green house gas (GHG) emissions from biofuel policies, specifically on (non-observed) land-use change (LUC) effects involve two main topics: (i) the limitations on the existing methodologies, and (ii) how to isolate the effects of biofuels. This paper discusses the main methodologies currently used by policy-maker...

Haque, Samiul. Ph.D., Purdue University, December 2014. US Commodity Support Payments: On Allocation of Resources and Fairness, Post 1996. Major Professor: Kenneth Foster This dissertation investigates the effect of US commodity support payment on agricultural producer decisions during the “decoupled” regime. Particular attention is paid to the national optimal output mix, input proportions, an...

The location of first generation processing plants for biogas using bulky inputs is a prominent example of locational decisions of plants that face high per unit transport costs of feedstock and simultaneously depend to a large extent on feedstock availability. Modelling the resulting regional feedstock markets then requires a spatially explicit representation of demand. With production capacit...

The rapid expansion of commodity agriculture in tropical forest landscapes is a key driver of deforestation. To meet the growing demand from a more prosperous and expanding global population, it is imperative to develop sustainable commodity supply chains that support higher agricultural productivity, and that enable improved environmental, economic, and social outcomes. Interventions by commun...

Landless agricultural laborers and marginal farmers constitute much of India’s poor. As population growth increases and more people enter an expanding rural labor force, either they must eke out a living in the rural sector or add to the growing pressure on the country’s urban areas. Meanwhile, agricultural jobs are fewer and the corresponding wages have been persistently below subsistence leve...
