Thesis title

Risk and vulnerability to extreme weather events: the case of urban and peri-urban agricuture in São Paulo cityems: to drought in peri-urban agriculture in São Paulo city

Thesis abstract

São Paulo is south-America's largest metropolitan region, and it has been experiencing severe water shortages since 2010, raising concerns about the future of water supply. Fresh water reservoirs reached its lowest levels during 2013/2014, due to the lack of rain accompanied by a heat wave, reaching the warmest summer in 55 years in 2015.

These events are a relevant example of increased vulnerability to extreme weather events in cities. Specific impacts of drought are expected to increase the vulnerability of agricultural systems and reinforce factors affecting them like rising demand for food and the decrease on yields due to the changes on rainfall patterns and extreme temperatures, conflicts over scarce resources (land tenure, water, biofuels, etc.), and chronic poverty.

Facing these challenges there is a strong need on finding strategies that enhance the resilience and adaptive capacity of these systems, through an integrative understanding of the socio-ecological systems dynamics and their vulnerability to extreme weather events at the local level.

This research aims to assess the vulnerability and risk to extreme weather events of urban and peri - urban agriculture (UPA) in São Paulo city and its potential for adaptation. Aimed to develop a set of indicators that evaluate vulnerability within its three domains: exposed elements, susceptibility and capacities and the identification of the adaptation strategies and technologies available to enhance resilience and reduce vulnerability to extreme weather events.
