Session at DNC 2017 // Resource Recovery and Reuse in Multifunctional Land-Use Systems
This session is focused on multifunctional land-use systems in dry areas of the world where freshwater scarcity, water quality deterioration, and land degradation may compromise the achievement of sustainable development goals, in particular SDG 2 addressing sustainable agriculture and food security, SDG 6 ensuring water and sanitation for all, SDG 13 on combating climate change, and SDG 15 on reversing land degradation. Eradicating extreme poverty and meeting the SDGs without adequately addressing such underperforming land and water resources are highly unlikely.
Session at the Dresden Nexus Conference 2017 "SDGs and Nexus Approach - Monitoring and Implementation", 17-19 May 2017
With increasing research-based evidence, a range of once apparently considered wastes have been found to be valuable resources with multiple uses and benefits including provision of ecosystem services. While considering multifunctional land-use systems, this session in general addresses resource recovery and reuse from the following so-called wastes, but not limited to them: liquid waste streams such as wastewater generated from household, municipal, and industrial sectors; and saline water generated by irrigated agriculture or pumped from saline aquifers. The session also addresses certain solid wastes such as biosolids/sewage sludge produced in wastewater treatment plants and phosphogypsum produced in phosphate industry. The multifunctional land-use systems in general may consist of agriculture, aquaculture, agroforestry systems, and groundwater recharge; but not limited to them.

Objectives and expected outcome
This session addresses the following key questions:- What are major roadblocks in resource recovery from certain so-called wastes for use in multifunctional land-use systems?
- What catalysts can fast-track the paradigm shift towards resource recovery reuse rather than continuing disposal or poorly managed applications leading to environmental and health implications?
Following are the expected outcomes
- Awareness on the potential resource recovery from certain wastes for their use in multifunctional land-use systems for environmental, health, economic, and social benefits
- Identification of barriers and opportunities for resource recovery and reuse in multifunctional land-use systems
Target audience
Relevant policy makers and institutions, farmers and water-user associations, marketing entrepreneurs, researchers, and professionalsAgenda
