Quiz 1. What is the definition of green water?

Classification Description Green Water Soil moisture from infiltrated rainfall available for uptake by plants. Scope Blue Water Rain water run-off occurring in streams, rivers, wet-lands, dams, lakes and aquifers. Grey water Waste water from domestic or commercial sources (not contaminated by toxic pollutants). Black water Water contaminated by organic or inorganic pollutants, especially faecal matter. Green water Enhanced rainfed agriculture • Essential part of the water cycle • Umbrella term for on farm techniques and approaches to manage green water • Water availability determines productivity: derived from rainfall that is available in the soil for • Includes concepts such as Conservation plant growth through transpiration Agriculture, soil health, regenerative agriculture, • Opportunity for change: managing green water rainwater harvesting ✓ Water capture increases water availability by reducing rainwater Reference: Falkenmark & Rockstrom runoff and groundwater seepage ✓ Water storage reduces evaporation
