Abstract. A comprehensive assessment of policy impact on greenhouse gas (GHG) emissions from agricultural soils requires careful consideration both socio-economic aspects and the environmental heterogeneity landscape. We developed a modelling framework that links large-scale economic model for agriculture CAPRI (Common Agricultural Policy Regional Impact assessment) with biogeochemistry DNDC (DeNitrification DeComposition) to simulate GHG fluxes, carbon stock changes nitrogen budget in...
This paper reviews and discusses the more recent literature application of Positive Mathematical Programming in context agricultural supply models. Specifically, advances empirical foundation parameter specifications as well economic rationalisation PMP models – both criticized earlier are investigated. Moreover, provides an overview on a larger set with regular/repeated policy that apply variants PMP. Results show most applications today avoid arbitrary rely exogenous information responses...
Bioplastic production is a small but fast growing sector in the global bioeconomy, which may benefit from public support measures future as governments seek to promote more sustainable consumption patterns. Here we assess potential net economy-wide impacts of 5% bioplastic target relative current plastic main producing regions. We compare two alternative policy strategies achieve general equilibrium framework that allows for substitution between conventional and bio-based plastics: subsidy...
Plot sizes and farm-plot distances affect the economic performance of agricultural production. Their effects likely differ between conventional organic farming systems due to major differences in crop production programs. Our paper quantifies these based on big data resource requirements field operations, summarized by regression models. Combined with detailed case study information obtained through interviews, we assess plot size distance for three farms which recently converted farming....
Expanding the production of fuels and fibres based on traditional food crops can put additional pressures ecosystems natural resources, with potential spillover effects through induced land use change (iLUC). Computable General Equilibrium (CGE) modelling provides a systematic framework for ex-ante sustainability analysis, capturing complex interactions between uses, agri-food markets, international trade. This study applies an integrated CGE that considers loss vegetation to derive...
Pastureland maintenance is seen as a land-based measure to reduce dependency on feed concentrates and mitigate greenhouse gas (GHG) emissions from livestock production in the EU, while providing other ecosystems services. This paper assesses potential market-mediated impacts, including global Land Use Change (LUC) GHG emissions, increased subsidies pastureland-based sectors EU. A tax recycling strategy (TRS) simulated against baseline up 2030 under shared socioeconomic pathway 2 (SSP2)....
Abstract In this study, we analyse how three scenarios involving different levels of harmonisation common agricultural policy (CAP) decoupled payments in the EU affect distribution farm income across regions and types. We use type extension impact (CAPRI) model, which captures heterogeneity EU. The first scenario (NUTS1) assumes uniform per‐hectare at NUTS1 level. second (MS‐CONV) equalises rates inside each Member State (MS) partially harmonises single payment scheme (SPS) MS line with 2011...
Mathematical programming models have received renewed interest in the area of agricultural and agri-environmental policy analysis. Their ability to explicitly represent physical constraints makes them specifically suited for connecting economic bio-physical aspects systems. Furthermore, they allow a direct representation many current measures related production activity levels. The introduction Positive Programming (PMP) addressed problems with plausibility simulated behaviour lack empirical...
When modelling medium and long-term challenges we need a reference path of economic development (the so-called baseline). Because sectoral models often offer more fundamental understanding future developments for specific sectors, many CGE modeling teams have adopted different kinds linking approaches to generate baselines. We systematically compare discuss the baseline calibration procedure, best practices pitfalls. identify types which divide into a) links with partial equilibrium models,...
Deciding on which crop to plant a field and how fertilize it has become increasingly complex as volatile markets, location factors well policy restrictions need be considered simultaneously. To assist farmers in this process, we develop the web-based, open source decision support system 'Fruchtfolge' (German for 'crop rotation'). It provides makers with coarse manure fertilization management recommendation each based solution of single farm optimization model. The model accounts specific...
Programmation mathématique positive avec observations multiples : estimation en coupes transversales Cet article présente une approche visant à spécifier des fonctions de coût non linéaires dans le cadre modèles programmation régionaux. La méthodologie question peut être considérée comme application la (PMP) multiples. L'application PMP les d'offre produits agricoles s'est sensiblement développée au cours ces dix dernières années. Cependant, beaucoup modélisateurs n'ont pas fait état du...
We present CGEBox, an open-source and open-access framework for regional global Computable General Equilibrium analysis realized in the Algebraic Modeling System (GAMS) software. It flexibly depicts different nestings production factor supply, supports functional forms demand choices modeling international trade sectors (Armington, Armington plus Constant Elasticity of Transformation to distribute Melitz Krugman model). Either a household approach or separate accounts government potentially...
