Coffee can be considered an important source of mineral nutrients. Since coffee is normally consumed through infusion, the availability of nutrients is related to the solubility, that is strongly influenced by the cultivation system applied to its production, which can influence the form of minerals are storage in the coffee bean. Coffee development is influenced by nutrient absorption, metabolism and storage. This study investigated the influence of cultivation on these characteristics of conventional and organic commercial coffee. The average concentration for conventional and organic cultivation determined in this study was 45.5 ± 11.2 and 64.7 ± 9.2 mg kg− 1 respectively. This result may be related to soil characteristics, such as acidic pH and reducing environment, favored by organic cultivation and favoring Mn solubilization in the soil solution, leading to greater Mn uptake. Principal component analysis shows differences between organic and conventional samples in the fractionation study. The characterizing fraction of the organic samples was the lipid and all other fractions characterized the conventional samples. This behavior suggests an influence of cultivation on Mn metabolism and storage by coffee. However, despite these observed differences, the average levels of Mn extracted from coffee infusions did not differ significantly between cultivation.

The SJVG-MAS Project addresses, in an interdisciplinary approach, the development of MAS-based tools for the simulation of the social production and management processes observed in urban ecosystems, adopting as case study the social vegetable garden project conducted at the San Jerónimo Park (Seville/Spain), headed by the confederation “Ecologistas en Acción.” The authors aim at the analysis of the current reality of the SJVG project, allowing discussions on the adopted social management processes, and also for investigating how possible changes in the social organization (e.g., roles assumed by the agents in the organization, actions, behaviors, (in)formal interaction/communication protocols, regulation norms), especially from the point of view of the agent's participation in the decision making processes, may transform this reality, from the social, environmental and economic point of view, then contributing for the sustainability of the project. The MAS was conceived as a multi-dimensional BDI-like agent social system, involving the development of five components: the agents' population, the system's organization, the system's environment, the set of interactions executed among agents playing organizational roles (e.g., communication protocols for reaching agreements) and the normative policy structure (internal regulation established by SJVG community). The aim of this chapter is to discuss the problems faced and to present the solution found for the modeling of SJVG social organization using JaCAMo framework. The chapter shows the integration of the considered dimensions, discussing the adopted methodology, which may be applied in several other contexts.
