“…First, small farmers have not been economically competitive under recent economic conditions. Bert et al (2011) showed that farmers operating small areas (e.g., <200 ha) were unable to generate sufficient income to cover household and production costs. As result, many of them have left active production and rented out their farms (Cloquell et al, 2005;Piñeiro and Villarreal, 2005).…”

“…LARMA is integrated into a comprehensive ABM designed to explore structural and land use changes in Argentine agriculture, namely the Pampas Model (PM) (Bert et al, 2011). The purpose of the PM was exploring three main patterns observed in recent decades in the Pampas: (1) an increase in the area operated by individual farmers, accompanied by a concomitant decrease in the number of active farmers; (2) an increase in the amount of land operated by tenants; and (3) an expansion of agriculture, and particularly of soybeans, with the displacement of other crops, pastures, and native grasslands.…”

a b s t r a c tLand exchange through rental transactions is a central process in agricultural systems. The land tenure regimes emerge from land transactions and structural and land use changes are tied to the dynamics of the land market. We introduce LARMA, a LAnd Rental MArket model embedded within the Pampas Model (PM), an agent-based model of Argentinean agricultural systems. LARMA produces endogenous formation of land rental prices. LARMA relies on traditional economic concepts for LRP formation but addresses some drawbacks of this approach by being integrated into an agent-based model that considers heterogeneous agents interacting with one another. PM-LARMA successfully reproduced the agricultural land tenure regimes and land rental prices observed in the Pampas. Including adaptive, heterogeneous and interacting agents was critical to this success. We conclude that agent-based and traditional economic models can be successfully combined to capture complex emergent land tenure and market price patterns while simplifying the overall model design.

“…The problematic behavior perceived from empirical knowledge and observed data is the reference mode. The consistency between model behavior and the reference mode is one of the factors that enhances trust in the developed model (Vennix 1996, Solecki and Oliveri 2004, Happe 2005, Bert et al 2011.…”

Abstract:In spite of a growing interest in organic agriculture; there has been relatively little research on why farmers might choose to adopt organic methods, particularly in the developing world. To address this shortcoming, we developed an exploratory agent-based model depicting Philippine smallholder farmer decisions to implement organic techniques in rice paddy systems. Our modeling exercise was novel in its combination of three characteristics: first, agent rules were based on focus group data collected in the system of study. Second, a social network structure was built into the model. Third, we utilized variance-based sensitivity analysis to quantify model outcome variability, identify influential drivers, and suggest ways in which further modeling efforts could be focused and simplified. The model results indicated an upper limit on the number of farmers adopting organic methods. The speed of information spread through the social network; crop yields; and the size of a farmer's plot were highly influential in determining agents' adoption rates. The results of this stylized model indicate that rates of organic farming adoption are highly sensitive to the yield drop after switchover to organic techniques, and to the speed of OPEN ACCESSLand 2015, 4 980 information spread through existing social networks. Further research and model development should focus on these system characteristics.
