Significant damage to surface water is caused by cattle husbandry. Only one global approach of water management and farming techniques (breeding management and cultivation methods) will ensure significant results. A pilot study run in the west of France proved that water quality can easily be improved by renovating the cattle buildings. It also showed that manure used as a fertilizer covers cultivation needs, which allows substantial savings for the farmers.

Restoration and enhancement of Lake Okeechobee and the Florida Everglades requires a comprehensive approach to manage agricultural runoff. The Florida Surface Water Improvement and Management (SWIM) Act of 1987 was promulgated to develop and implement plans for protecting Florida waters. The South Florida Water Management District was directed by Florida legislature to develop management plans for Lake Okeechobee (SWIM) and the Everglades ecosystem (Marjory Stoneman Douglas Everglades Protection Act of 1991). These plans require agriculture to implement best management practices (BMPs) to reduce runoff phosphorus (P) loads. The Lake Okeechobee SWIM plan established a P load reduction target for Lake Okeechobee and set P concentration limitations for runoff from non-point source agricultural sources. Agricultural water users in the Everglades Agricultural Area (EAA) are required to develop farm management plans to reduce P loads from the basin by 25%. The Everglades Forever Act of 1994 additionally emphasized linkage of these landscapes and consequent protection and restoration of the Everglades. Agricultural BMPs are being developed and implemented to comply with water management, environmental, and regulatory standards. Although BMPs are improving runoff water quality, additional research is necessary to obtain the best combination of BMPs for individual farms. This paper summarizes the development of comprehensive water management in south Florida and the agricultural BMPs carried out to meet regulatory requirements for Lake Okeechobee and the Everglades.

Las cisternas son el principal medio de aprovisionamiento de agua en las ciudades romanas en muchos casos. La historiografía ha identificado la existencia de un verdadero modelo de gestión del agua que emplea únicamente estas construcciones, o bien que las utiliza en conjunción con otros medios, como el aprovechamiento de aguas subterráneas mediante pozos. Partiendo desde una conceptualización teórica del término latino cisterna, realizamos un recorrido en la identificación de este modelo en casos específicos de Hispania como marco general del estudio, y en la provincia Ulterior Baetica como marco particular.Water storage cisterns are the main source of water supply in roman cities in many cases. Their existence has been identificated as a water management model which employs these hydraulic infrastructures exclusively, or together with others forms as groundwater extraction by wells. Starting to a theoretical conceptualization of the latin term cisterna, we carry out a review to identify this model in specific cases in Hispania as general spatial framework, and in Hispania Ulterior Baetica province as particular framework.
