Question restatement: The prompt asks which items were included in the Green Water conservation and sustainable water management approaches described near the end of Dr. Lenhart's presentation, for a multiple-answers selection.
Option analysis:
- use of crops that use less water (have a lower crop coefficient): This type of recommendation aligns with Green Water strategies by minimizing evapotranspiration demands and reducing overall water use through selecting crops with inherently lower water requirements. In practice, crop coefficients (Kc values) are used to estimate water needs, so choosing crops with lower Kc is a direct method to conserve water and promote sustainability.
- drip irrigation to reduce water loss: Drip irrigation delivers water directly to the root zone with minimal evaporation and runoff, which is a cornerstone technique in efficient irrigation. It reduces water losses compared to surface or flood irrigation and commonly appears in discussions of water-conscious agricultural practices, including Green Water concepts.
Gaps and considerations:
- The question mentions a list described by Dr. Lenhart, but the provided material here lacks the full set of Green Water options to evaluate. Without the complete list of candidate items, it’s not possible to compare every possible option, explain why each non-listed item would be included or excluded, or identify other potential Green Water measures that might appear in the list.
- If there were additional options such as changing irrigation timing to cooler parts of the day, use of soil moisture sensors, rainwater harvesting, or adopting drought-tolerant crop varieties, each would require assessment of how well it aligns with Green Water principles and the specific context of Lenhart’s presentation. In general, techniques that reduce water input, improve efficiency, or lower crop water demand would be consistent with Green Water goals.
- For any option not explicitly provided here, the reasoning would include: does the option reduce water use, does it minimize losses (evaporation, deep percolation, or runoff), is it compatible with local agronomic and economic conditions, and does it reflect sustainable water governance as described in the presentation.
In summary, the two items listed—selecting crops with lower water requirements and implementing drip irrigation to cut losses—fit well with Green Water strategies as described relative to efficient water use and reduced waste. Additional evaluation would require the complete set of candidate options from the presentation to contrast how each aligns with Green Water concepts.
