The Principles for Responsible Investment in Agriculture and Food Systems (CFS-RAI) are shown as suitable instruments to contribute to the Sustainable Development Goals (SDG) in rural areas. Local Action Groups (LAGs) have proven to be effective governance structures for the implementation and management of rural development projects based on participation and collective action. This research integrates the implementation of the LAG from the CFS-RAI Principles for the design of a rural development strategy. The foundations of these new structures are analyzed and the process of creating a LAG linked to the El Mantaro Regional Development Center (RDC) of the Universidad Nacional Mayor de San Marcos (UNMSM), in the Junín region (Peru), is described. The methodological process incorporates the “Working With People” (WWP) approach and the LEADER (Liaison Entre Actions de Développement de l’Économie Rurale) specificities for the analysis of empirical information obtained in surveys and workshops, with 350 people involved in the process. The results indicate that the LAGs, as multi-stakeholder partnerships linked to the RDC, are a novel way to integrate the CFS-RAI principles from participation, proximity management, strengthening local communities and promoting sustainable development through projects. These results contribute to the empowerment of civil organizations and motivate their participation in local political decisions related to sustainable rural development.
The effect of vital area on productive and reproductive performance was evaluated in 2,325 guinea pigs at IVITA El Mantaro Research Station (300 growing male and female guinea pigs, 750 fattening male and female guinea pigs and 200 female and 25 first mating male guinea pigs). The study was divided in seven assays. Five different vital areas and five different number of animals per well were evaluated in each assay. A total of 25 wells were used for each assay. Different variables (body weight gain, alfalfa intake, feeding convertion index, number of scars due to fights, litter size, mortality and profit/cost index) associated to each productive phase were analyzed. Larger vital areas in assays that involved growing and fattening males resulted in greater body weight gain, lower alfalfa intake, lower feeding convertion index and lower number of scars due to fights. All of these variables showed significant lineal response patterns (p = 0.0001 to 0.02 for growing males and p = 0.0001 to 0.0007 in fattening males). The same pattern was shown for growing females except for body weight gain. For fattening females, weight gain and profit/cost index were adjusted to cuadratic regresion reaching a biological and an economic optimum at 0.19 and 0.18 m 2 /guinea pig. The following vital areas were recommended: 0.16 m 2 /guinea pig for growing males, 0.14 m 2 /guinea pig for growing females, 0.24 m 2 /guinea pig for fattening males, 0.18 m 2 /guinea pig for fattening females, and 0.28 m 2 /guinea pig for breeding animals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
