Perspectives are like filters: they compile and structure the information that relate to a given focus theme, region or context. This allows you to quickly navigate to the content of your particular interest while promoting the holistic understanding of sustainable sanitation and water management.

The introduction of on-site sanitation systems might lead to groundwater contamination. The purpose of this manual is to provide guidance on how to assess and reduce the risk of contamination of groundwater supplies from on-site sanitation systems and is aimed at those responsible for planning low cost water supply and sanitation schemes.

The new process is inspired by the practices of the pre-Colombian culture in the Amazonian region that produced highly fertile anthropogenic soil (terra preta).

The composition of terra preta and the importance of charcoal and other ingredients for the formation and their carbon sequestration capacity are discussed. There is an outlook on how to recreate this very useful and nutrient rich type of earth in a synthetic way by mentioning current sources and studies.

The paper describes the bacterial diversity and community structures of a pristine forest soil and an anthropogenic terra preta from the Western Amazonian forest using molecular methods to identify the predominant phylogenetic groups. The survey provides a detailed analysis of the composition and structure of bacterial communities in terra preta anthrosols.

The effects of lactic-aid conditions in urine-separation dry toilets and a subsequent treatment by vermicomposting are assessed. Research focused on analysing standard chemical and biochemical properties of the toilet products to evaluate their stability and maturity, and establish nutrient status.

LID comprises a set of approaches and practices that are designed to reduce runoff of water and pollutants from the site at which they are generated. By means of infiltration, evapotranspiration, and reuse of rainwater, LID techniques manage water and water pollutants at the source and thereby prevent or reduce the impact of development on rivers, streams, lakes, coastal waters, and ground water.
