Confronting Agrarian Crisis And Deconstructing Farmer Debt: The Story Of Sulthanpur Village, Andhra Pradesh, Erica Dejong Apr 2012

Confronting Agrarian Crisis And Deconstructing Farmer Debt: The Story Of Sulthanpur Village, Andhra Pradesh, Erica Dejong

Independent Study Project (ISP) Collection

In a climate of globalized politics and neoliberal economics, it can be difficult to isolate the impacts of agricultural and economic policy on the lives of the rural poor in India. Hidden behind a veil of economic growth, pro urban, and pro industry governments, the stories of small and marginal farmers have been overlooked in the name of different development priorities. This study endeavors to put the agrarian poor back into the scholarship spotlight by deconstructing livelihood crises and farmer debt in Sulthanpur Village, Andhra Pradesh. This effort is important because although Andhra Pradesh has the highest rate of farmer …

Riparian Conundra, David Weaver Jan 2010

Riparian Conundra, David Weaver

Conference papers and presentations

Riparian vegetation is established or restored on the basis that it physically filters and traps hillslope derived particulate nutrients in surface runoff. Whilst many studies support this conventional model of riparian function, few test this models embedded assumptions. The assumptions are that catchments are surface runoff dominated, that most surface derived nutrients are transported in particulate form, and that riparian management targets locations that will result in the greatest change in water quality. This paper reviews studies in south west Western Australia that challenge these assumptions. Plots measuring leaching and runoff of nutrients showed that 20 times more water and …
