Assessing farm innovations and responses to policies: A review of bio-economic farm models

Cost-effective water quality improvement in linked terrestrial and marine ecosystems: a spatial environmental - economic modelling approach

“…Several approaches combine land-use models with hydrological, ecological and/or soil models, in which environmental externalities from agricultural production impacting the downstream environment are analysed (for an overview, see Nelson 2002;Elofsson et al 2003;Janssen and Van Ittersum 2007). Some studies have related land-use location and associated biophysical conditions to economic production potentials, but have either ignored or failed to spatially explicitly account for environmental impacts (see e.g.…”

Development of a broadened cognitive mapping approach for analysing systems of practices in social–ecological systems

“…The outputs of such studies provide a good understanding of the studied situations, but they are not easy to incorporate into bio-economic simulation (Mathieu, 2004;Papy, 2004). Conversely, the technical approaches involve studying complex interactions among elements of the studied systems (Janssen and van Ittersum, 2007;Darnhofer et al, 2010). They use theories from artificial intelligence or management science in order to build farming systems models and decision-support systems (Aubry et al, 1998;Girard and Hubert, 1999;Dounias et al, 2002;Keating et al, 2003;Cros et al, 2004;Louhichi et al, 2004;Merot et al, 2008;Vayssieres et al, 2009).…”

Development of business capacity and organization of commercial business of farmer based organizations in the northern intervention zone in Ghana: A case study of nine-farmer based organizations

“…Postharvest technologies were not available for farmers and they depended on indigenous technologies, similarly indicated by other authors [9][10][11][12]. Markets accessibility was difficult for farmers due to unavailability of transport and inaccessible roads.…”

“…Farmers' lack of access to technical information stands out as a major obstacle to improving food production in Ghana. Generally, lack of technical information for farmers, which is hampering crop production, had been observed by different authors [5,[9][10][11][12]. Similarly, a typical information and signing of contract farming assist in reduction of transactions costs caused by market limitations and creates better environment to integrate primary producers with marketers and agro-industries [13][14][15][16].…”
