Water and sanitation

Maize growing under plastic

Critics claim that maize can cause unwanted environmental impacts. But supporters of the crop are able to show how by use of cover crops it can be grown responsibly, reducing or eliminating, for example, nutrient leaching and soil erosion. In south-west England, a Wessex Water project is using cover crops to protect and improve drinking water quality by working with growers whose farms surround boreholes and reservoirs that supply water for human consumption. Steps like this can contribute to SDG 6 to ensure sustainable management of water and SDG 12 to ensure sustainable production.

Giving the World Access to Water - Elsevier Atlas
Despite the increased attention the sixth Sustainable Development Goal (clean water and sanitation) has brought, access to water in Sub-Saharan Africa is worse than ever: there are more people without access to water now than there were in 1990. In order to fix the problem we need to understand what’s going wrong with our current approaches. That was the aim of an Atlas Award-winning study published in Water Resources and Rural Development, by researchers at Glasgow Caledonian University in Scotland, the University of Malawi in Malawi and the University of Lusaka in Zambia. Interestingly enough, since women and school aged girls are typically tasked with water fetching, by providing water access and sanitation authors feel there is an effect on others SDG like SDG 10 (reduced inequalities), SDG 4 (quality education) and SDG 5 (gender equality)
Effective communication to citizens is of prime importance during public health crises involving water. This paper takes a sequential mixed method approach to the problem of communicating drinking water risks prevention of exposure to health risks in cities, related to SDG 6: clean water and sanitation.
The expansion and operation of water supply systems under growing demands, hydrologic variability, and water scarcity requires strategic decisions on supply sources for reducing and improving reliability and flexibility. This paper provides an integrated framework to optimize water supply system expansions using dynamic programming and combining short and long term water supply source optimization using quadratic programming. This relates to SDG 6.
The Blueprint for Business Leadership on the SDGs aims to inspire all business — regardless of size, sector or geography — to take leading action in support of the achievement of the Sustainable Development Goals (SDGs). It illustrates how the five leadership qualities of Ambition, Collaboration, Accountability, Consistency, and Intentional can be applied to a business' strategy, business model, products, supply chain, partnerships, and operations to raise the bar and create impact at scale. The Blueprint is a tool for any business that is ready to advance its principled approach to SDG action to become a leader. This chapter relates specifically to SDG 6.

As the climate continues to change, climate scientists have projected changes in water quantities available for human and other uses. This quantitative study examines how in the US, state water plans and state hazard mitigation plans address climate change. The primary objective of this study is to determine what drives states to plan for the impacts of a changing climate, addressing SDG 13 on climate action.

Urban water management via Sustainable Urban Drainage Systems (SuDS) has been successfully applied in cities worldwide. The economic feasibility of SuDS in London improves when considering wider benefits. The investment of stakeholder groups is broken down proportional to their benefits. A financial scheme was defined to facilitate SuDS uptake in London based on available incentives and private investment. This is a straightforward methodology that uses available tools and data, to improve SuDS feasibility in planning phases, related to SDG 6.
An agent-based model is created using data for household characteristics and outdoor water use to calculate water demands. This model represents utility response to water shortages to enact residential restrictions. The agent-based model is coupled with reservoir simulation for a case study, and results are compared to historic data. Sustainability of water policies is evaluated for climate scenarios created using a stochastic reconstruction framework. This is related to SDG 6.
Urban source separation infrastructure systems have a promising potential for a more sustainable management of household food waste and wastewaters. A renewed trend of larger implementations of pilot areas with such systems is currently emerging in Northern Europe. This study investigates the drivers behind the decision of stakeholders to implement source separation systems as well as the importance of the previously existing pilot areas in the decision-making process.
An international review of stormwater regulation and practices, especially for low-exposure, landscape irrigation schemes in urban environments, was undertaken with a view to identifying what could be used in Alberta, Canada. A general lack of clear guidance and regulation to manage stormwater quality and potential public health risks was identified, which could be hindering the uptake of stormwater schemes generally.This related to SDG6 and SDG 11.
