Indicators are increasingly recognized as an important decision aid tool to translate sustainability issue from theory into practice. However, indicator development for sustainable community development is rather successful than the agricultural sector due to methodological lacuna. The aim of this study is to develop a methodological framework for indicator development and an essential set of i...

A cross-sectional survey of agricultural areas, combined with routinely monitored mosquito larval information, was conducted in urban Dar es Salaam, Tanzania, to investigate how agricultural and geographical features may influence the presence of Anopheles larvae. Data were integrated into a geographical information systems framework, and predictors of the presence of Anopheles larvae in farmin...
