317 citations
••
TL;DR: In this article, the authors revisited this issue from a number of angles: current approaches to enlisting SSA smallholders in agricultural development; the history of the phenomenal productivity growth in the USA, The Netherlands and Green Revolution Asia; and the current framework conditions for SSA productivity growth.

240 citations
••
TL;DR: The FarmDESIGN model is presented, which has been developed to overcome limitations by coupling a bio-economical farm model that evaluates the productive, economic and environmental farm performance, to a multi-objective optimization algorithm that generates a large set of Pareto-optimal alternative farm configurations.
193 citations
••
TL;DR: In this paper, the authors examine the integration of Australian cropping and livestock production from three perspectives: as a factor in land use change, a consequence of individual management practices and a means of meeting farmers' multiple objectives.
184 citations
••
TL;DR: In this article, the authors developed an LCA model to compare contrasting milk production systems, a seasonal pasture-based dairy farm and a confinement dairy farm, and found that when expressed per unit of milk and per on-farm area, all total environmental impacts were greater for the confinement system compared to the grass-based system.
173 citations
••
TL;DR: In this paper, the authors used regression models to explain the decision-making processes of smallholder farmers adopting the system of rice intensification (SRI) in Timor Leste, and found that participation in training programs and household labor availability increase the probability and intensity of adoption.
168 citations
••
TL;DR: In this paper, a study of six Australian dairy farms installing new precision dairy farming technology was undertaken to develop an in-depth picture of the issues occurring at the interface where precision farming data and decision-making meet.
161 citations
••
TL;DR: The potential of the Tradeoff Analysis model for Multi-Dimensional Impact Assessment (TOA-MD) to provide a flexible, generic framework that can use available and modeled data to evaluate climate impact and adaptation strategies under a range of socio-economic scenarios is shown.
153 citations
••
TL;DR: In this article, the authors explored farmers' knowledge regarding how trees affect coffee productivity and ecosystem services in Costa Rica and concluded that technical interventions addressing the improvement of coffee plantations are more likely to be successful if they take into account not only the scientific information on agroforestry interactions but also the knowledge possessed by farmers.
••
TL;DR: In this article, the authors performed a case-study approach to perform an in-depth investigation of 4 sheep meat and dairy farms with different intensities of reproduction management, which resulted in the selection of 37 sustainability indicators that were classified according to the systemic attributes defined by MESMIS.
••
TL;DR: Empirical evidence presented in this article shows that whilst this was the case for the 1950–1975 period, the pattern of cattle production in Brazil has changed profoundly since then and an additional pasture area that is 25% higher than the Amazon biome in Brazil would be needed to meet current levels of Brazilian beef production.
••
TL;DR: In this article, the authors explore the association between different forms of social capital and innovation in agriculture, for a sample of African countries, and find mixed evidence that structural social capital, especially in the form of connections beyond the village, is associated with more extensive adoption of innovations, the reverse is true for cognitive social capital (capturing shared norms and trust within the local community).
••
TL;DR: In this article, a stochastic tactical planning model for the production and distribution of fresh agricultural products is presented, which incorporates the uncertainties encountered in the fresh produce industry when developing growing and distribution plans due to the variability of weather and demand.
••
TL;DR: In this paper, a survey conducted between October and December of 2005 was designed and implemented in order to determine the socioeconomic and production characteristics for 319 farmers in 32 watersheds in Central Chile and the number of water conservation practices implemented by farmers was examined using a Poisson count data model, and the types of practices were evaluated using Logit and Multinomial Logit models.
••
TL;DR: In this article, the authors used data from a unique panel survey of cotton farmers conducted in India between 2002 and 2008 and showed that the Bt pesticide reducing effect has been sustainable.
••
TL;DR: In this article, the authors investigated information network structures within the agrarian environment in order to understand the barriers to, and development of, effective farm management, specifically the management of agrodiversity.
••
TL;DR: In this paper, an integrated analysis at the catchment scale is undertaken to assess the agricultural land management changes required to achieve this target, and to evaluate the cost-effectiveness of these changes.
••
TL;DR: Investigation of the functions of design process outputs as boundary objects in the implementation of novel agricultural production system concepts confirms that a design process output such as a scale model can be purposefully created to serve as a boundary object and support novel agricultural system concept implementation.
••
TL;DR: In this article, a case study is presented to assess the water footprint of New Zealand dairy farming in two contrasting regions of Waikato (North Island, non-irrigated moderate rainfall) and Canterbury (South Island, irrigated low rainfall), and illustrate differences in water footprint methods and evaluate the suitability of indicators derived from each water footprint method.
••
TL;DR: In this article, the authors used the Rothamsted carbon model (RothC) to predict changes in soil organic carbon under different land uses and the different climate that may occur in the future.
••
TL;DR: In this article, the costeffectiveness of alternative land-use and land-management practices that can increase soil carbon sequestration is analysed by integrating biophysical modelling of carbon sequestering with whole-farm economic modelling.
••
TL;DR: In this paper, the authors compared energy and greenhouse gas (GHG) balances and biodiversity impacts of different farming systems by using LCA accompanied by an assessment of alternative land uses.
••
TL;DR: In this paper, a simple model that includes the most influential drivers of land use changes and their impacts in the land use system is developed to explore the impacts of important and realistic alterations in those factors driving land use change.
••
TL;DR: A survey was conducted in the spring of 2010 to characterize the use of nitrogen (N) fertilizer on corn (Zea mays L.) by Minnesota farmers in the 2009 growing season as discussed by the authors.
••
TL;DR: In this paper, photo-elicitation is used to compare the landscape perceptions of HM graziers with those of more conventional graziers, based on their choice of photo targets and the stories those photographs elicited.
••
TL;DR: In this paper, the biological and physical processes of an intensively managed rotational pasture-based dairy and a confinement fed dairy in the southeastern United States were simulated with the Integrated Farm System Model (IFSM) to evaluate management effects on greenhouse gas emissions, soil carbon sequestration, carbon footprint, nitrate leaching, ammonia volatilization, erosion, phosphorus runoff, and phosphorus accumulation in the soil.
••
TL;DR: This study demonstrates the value-added outcomes that result from research that facilitates farmer–researcher collaboration to learn from, innovate and tailor management systems to fit local circumstances.
••
TL;DR: In this paper, the authors describe a process that has been developed to produce a map of agricultural profit for Australia for the year 2005/2006, which can be used in various land use management and economic scenarios and will represent a step forward regarding a scenario impact assessment on agricultural profits.
