1. Crop Yield Improvement
Let Yb be the crop yield before implementing smart irrigation and Ya be the yield after implementation. The yield improvement I can be represented as:
I=a(Yb)2+b(Ya)+cI = a(Yb)^2 + b(Ya) + cI=a(Yb)2+b(Ya)+c
For instance, if a=0.02a = 0.02a=0.02, b=-1.5b = -1.5b=-1.5, and c=10,000c = 10,000c=10,000, and the yields before and after implementation are 2,000 and 2,500 units respectively, the yield improvement III would be calculated by substituting these values into the quadratic equation.
2. Input Cost Reduction
Let Cb be the input cost before implementing smart irrigation and Ca be the cost after implementation. The cost reduction S can be represented as:
S=a(Cb)2+b(Ca)+cS = a(Cb)^2 + b(Ca) + cS=a(Cb)2+b(Ca)+c
For example, if a=0.05a = 0.05a=0.05, b=−1b = -1b=−1, and c=5,000c = 5,000c=5,000, and the costs before and after implementation are $100,000 and $80,000 respectively, the cost reduction SSS would be calculated accordingly.
3. Water Usage Efficiency
Let Wb be the water usage before, and Wa be the water usage after implementation. The efficiency improvement E can be represented as:
E=a(Wb)2+b(Wa)+cE = a(Wb)^2 + b(Wa) + cE=a(Wb)2+b(Wa)+c
For instance, if a=0.02a = 0.02a=0.02, b=-1.5b = -1.5b=-1.5, and c=100c = 100c=100, and the water usage before and after implementation are 10,000 units and 7,000 units respectively, the efficiency improvement EEE would be calculated by substituting these values into the quadratic equation.
4. Environmental Impact Reduction
Let Eb be the environmental impact measure before implementation and Ea be the measure after implementation. The reduction in environmental impact D can be represented as:
D=a(Eb)2+b(Ea)+cD = a(Eb)^2 + b(Ea) + cD=a(Eb)2+b(Ea)+c
For example, if a=0.01a = 0.01a=0.01, b=-0.5b = -0.5b=-0.5, and c=50c = 50c=50, and the environmental impact measures before and after implementation are 500 units and 350 units respectively, the reduction in environmental impact DDD would be calculated by substituting these values into the quadratic equation.
