“…La principal fuente de P como fertilizante es la roca fosfórica (RF), un recurso no renovable cuyas reservas se estima se agotarán dentro de 100 años (Cordell et al, 2009;Dawson y Hilton, 2011), con lo cual se visualiza un incremento en los precios de los fertilizantes fosforados (Cordell et al, 2011), aunado a problemas de abastecimiento de alimentos para una población mundial estimada en 9 billones de personas para el 2050 (Cordell et al, 2011;Dawson y Hilton, 2011).…”

“…Based on data about available reserves and according to existing current demands, Cordell et al (2011) points to the probable occurrence of a peak in exploitation of phosphatic rock reserves in the world around 2030. After this time, due to the exponential growth in the world population projected for the next fifty years, it is estimated that the availability of reserves and the ability to exploit them will be gradually reduced, being impacted by an increase in the cost of operation, a reduction in quality and an rise in the degree of technical difficulty in order to access remaining reserves.…”

Strategies for managing phosphorus in the environment have been considered to be of great significance. In light of debates about protecting water resources, tools for recovering and recycling phosphorus are being assessed, with the aim of guaranteeing the sustainability of natural reserves. This study discusses phosphorus dynamics in the environment and measures geared towards the management of its presence in water. In order to illustrate the situation in Brazil, we present an assessment of the size of the potential phosphorus load that is discharged daily into the Tietê River, State of São Paulo, by the urban population living in its basin. Due to its replacement in powdered detergents, the results showed a potential reduction in the amount of phosphorus discharged into the Tietê of about 11.7 t day -1 . The size of the potential phosphorus load that might be recovered from sewage sludge shows a scenario of great potential for re-using and recycling in agricultural areas, as long as the necessary care is taken regarding safety and environmental protection. Management methodologies, such as Cleaner Production (CP) techniques, are important tools for controlling water pollution, as they contribute to the reduction of phosphorus emissions. They can therefore improve the perception producers and consumers have of this issue, introducing reducing, recycling and recovering concepts, and assisting in compliance with public policies geared towards preserving the environment.Keywords: effluent, nutrients, water quality.A gestão do fósforo nas águas: estudo de caso do Rio Tietê, Brasil RESUMO O desenvolvimento de estratégias para gestão do fósforo nas águas tem sido considerado, cada vez mais, de grande importância para a manutenção da qualidade de vida. Assim, paralelamente às discussões sobre alternativas para promover a proteção das águas, são avaliadas ferramentas para controle das fontes e reciclagem do fósforo no meio ambiente, buscando garantir a sustentabilidade das reservas conhecidas e exploráveis. Face ao exposto, o objetivo deste trabalho é discutir a dinâmica do fósforo no meio ambiente e as medidas voltadas para a gestão de sua presença nas águas. A título de ilustração da situação vivenciada no Brasil a respeito desse assunto, apresenta-se um dimensionamento da carga potencial de fósforo lançada diariamente nas águas do rio Tietê, localizado no Estado de São Paulo, a partir da população urbana da bacia hidrográfica.

“…Water purifi cation : More than 80 % of the P and N used globally in agriculture is not taken up by vegetation; instead, it leaks out and effects other systems, i.e., terrestrial and aquatic ecosystems (Cordell et al 2011 ;Galloway et al 2010 ). There are even links to water quality related to overfi shing of oysters in Chesapeake Bay, USA, where these fi lter feeders maintained water clarity ).…”

Urbanization, Biodiversity and Ecosystem Services: Challenges and Opportunities

In this chapter we take a complex systems approach to exploring the linkages among the phenomenon of urbanization, the changing value systems and world perspectives of urban dwellers, the sometimes distant connections to the food production systems that support cities, and the often invisible ecosystem services that support food production and in turn are affected by food production.After we explore the relationship between a range of ecosystem services and their relationship to food production, we present three cases of economically developed cities that secure their food from global sources. The wealthy urban populations in all our three case cities adhere to the highly commoditized systems of industrial production based on energy-and material-intensive external inputs for the bulk of their food provision. Fully integrated into the global market, trade enables these cities to both consume and produce what their consumers desire without regard to the local capacity of ecosystems in the regions around the cities.
