Definition: Absolute amount of water saved is the 'surplus' water unused by the farmer who adopts water saving technologies and management practices, compared to the business-as-usual scenario. This indicator will be measured in the context of the inputs and outputs stated in indicator OC-11.2.

Unit of Measure: Cubic metres per hectare (m3/ha)

Disaggregated by: Production system, Main crop/livestock, geographic location (national, sub-national)
Production system: Crop, livestock, integrated crop-livestock
If crop or integrated crop-livestock system:

  • Main crop: Chickpea, lentil, faba beans, grass pea, spring barley, winter barley, durum wheat, spring bread wheat

    • Soil type: Heavy, light

    • Crop management: Good management, poor management

      • Good management practice: Break crops, summer weed control, early sowing, wider rows, irrigation timing/deficit irrigation regime, disease control, sub-soil manuring

    • Production/input system: Rain-fed only, mainly irrigated, mainly rain-fed with limited irrigation
      Main livestock: Goats, sheep, cattle

Method of Calculation:
Water saved (Ws)=Wt-WO
W0 denotes water used per hectare in the first reporting period (e.g baseline) and Wt denotes water usage per heactare in subsequent reporting periods (e.g mid-term, end-term).

Data sources: Farm households, farm records

Data collection method: Farm household surveys, document review

Data collection and reporting responsibility: Program leader, project leader, project M&E focal point person

Data Collection and Reporting Frequency: Annual, bi-annual, baseline, mid-term, end-term.

Evidence required:
For internal evaluation or research studies: Study protocol, data collection tools, dataset, report;
For external evaluation or research studies: Request for proposals (RFP) document, inception report, final report, dataset

Rationale: In addition to the rationale for OC-11.2, this indicator will provide information on the amount of water made available for other uses as a result of promoting genotypes and technologies that promote water efficiency within the ICARDA-mandated crops and livestock.
