La diversidad de actividades económicas de los grupos domésticos rurales en la valoración del riesgo por parte de las microfinancieras.

Colegio de Postgraduados

Sánchez González, Carmen Lissette.

El microcrédito es un servicio que las personas de bajos ingresos utilizan para contrarrestar su condición de pobreza ya que, cuando se encuentra a su alcance, pueden poner en marcha proyectos y/o actividades de tipo económico que contribuyen a mejorar sus ingresos. A pesar de que la importante función del microcrédito ha sido objeto de amplio reconocimiento, incluso por parte de organismos nacionales e internacionales, la cobertura en la atención de clientes sigue siendo muy limitada. La falta de cobertura, por parte de las Instituciones Microfinancieras (IMF), resulta particularmente aguda en el caso del sector rural como resultado de las complejas condiciones del mismo y de la restringida capacidad de las instituciones microfinancieras. No...

The Economic Impacts of Pollinator Declines: An Approach to Assessing the Consequences

Ecology and Society

Kevan, Peter G; University of Guelph; pkevan@uoguelph.ca; Phillips, Truman P; University of Guelph; truman@uoguelph.ca.

Since agricultural activities were first recorded, there have been shortages of pollinators. Today it seems that pollination systems in many areas of agriculture are threatened by the inadequacy or lack of sustainable managed, indigenous, or imported pollinators. Pollinator shortages can adversely affect crop production and commodity markets. This paper presents an economic model than can be used to measure some of the economic impacts of pollinator deficits on traded commodities. This economic analysis indicates that consumers of a commodity affected by a pollinator deficit may suffer because the commodity costs more and becomes less available. At the same time, although the producers of the affected commodity may experience crop declines, they may also...

Integrating local knowledge and science: economic consequences of driftwood harvest in a changing climate

Ecology and Society

The integration of local knowledge and science represents an opportunity to enhance the understanding of interrelations among climate, hydrology, and socioeconomic systems while providing mutual benefits to scientists and rural communities. Insight from rural Alaskans helped to identify a social-ecological threshold used to model potential driftwood harvest from the Yukon River. Information from residents of Tanana, Alaska, was combined with scientific data to model driftwood harvest rates. Modeling results estimated that between 1980 and 2010, hydrologic factors alone were responsible for a 29% decrease in the annual wood harvest, which approximately balanced a 23% reduction in wood demand because of a decline in number of households. The...
