Rural Support Networks in the UK and Canada: The Influence of the Patrilineal Culture of Family Farming

Rural support organisations have emerged since agricultural restructuring of the 1980s. The paper draws on research from the UK and Canada to suggest that the support in both countries is derived from a patrilineal culture that still dominates family farming. The paper begins by outlining a conceptual basis for arguing that such a culture can be understood as comprising of male and female relational gender identities capable of explaining farm relationships, farm survival and adjustment strategies and community engagement. These components, it is argued, are facets of the patrilineal farming culture which must be understood if its impacts on all its members are to be appropriately comprehended and supported.

The paper has two key aims, therefore. Firstly it suggests that a more nuanced understanding of farming „culture? which is persistently patrilineal in nature is now required which is capable of addressing the realities of farming individuals?
lives as they perceive them. The conceptualisation of such a culture is informed
by drawing on insights from gender theory, agricultural geography and rural studies. This conceptual discussion provides the context for the paper?s second aim which is to demonstrate how rural support in both the UK and Canada is derived „from? and is influenced by such a patrilineal culture . Findings are
presented identifying five key themes from this conceptualization which influence the support of such organisations. Thus, it is suggested, that the nature of rural support can be better understood and the appropriateness of the support interrogated when such conceptualization is taken on board.

Costs estimates and rentability of the guava culture (Psidium guajava L Paluma cv) in Monte Alto County, São Paulo State

This work intended to calculate the rentability of the guava culture Paluma cv. in Monte Alto region-SP, estimating the costs of the implantation, maintenance, production and the gross income of this culture in the first three years of cultivation. The production system utilized refers to the cultural treatments usually used in this culture in the region. The costs estimates were based on the total operational costs methodology used by the Agricultural Economics Institute (I.E.A.). The results obtained showed that the implantation and maintenance costs of the culture, in the two first years was R$7.402,3 l/alqueire*. Considering the possibility that in guava orchard, on irrigated conditions, reach in the fourthy year a productivity of 80t/alqueire and that the current price is R$0,20/kg, it is possible to estimate the gross income around of R$16.000,00/alqueire, resulting in a net income of R$9.497,06/alqueire.
