Massey University’s series of webinars through Autumn – “The NOW and the NEXT of LCA” focusing on carbon and water.
Each half-hour webinar will have a dedicated speaker and topic. The third webinar on the Water section of this series will be held on 18th May 2022: Water footprinting of agricultural products: the relevance of the local data and local context. The talk will be delivered by Dr. Ranvir Singh.
Water footprinting has been increasingly applied to assess freshwater use and its environmental impacts associated in the production of a wide range of goods and services, including agricultural products. This innovative approach provides an analytical tool to account for both direct and in-direct use of all freshwater components (green, blue and grey water) and characterise its impacts on water scarcity and water quality degradation. However, direct measurements of these freshwater components are practically challenging, and applications of different water footprinting methods and models pose uncertainty in comparative analysis of water footprinting of different products and processes.
In this webinar, Associate Professor Ranvir Singh (Massey University) will present and discuss effects of different water footprint methods, data sources, water use models, and scales of analysis on quantification of water footprints of milk production (dairy farming) in New Zealand, and two major crops (wheat and cotton) production in Northern India. The case studies will highlight the importance of the use of local data and local context in quantification and assessment of water footprints of agricultural products.
