“…Although the water requirements for irrigating potatoes are well known, the water requirements for storing, processing, and washing potatoes on the farm before processing are not well understood or reported (Statistics Canada 2010a). Because farmers use water sources that are not connected to water utilities, limited information has been gathered on actual water use (De Loë et al 2001). Filling this knowledge gap is important for guiding science-based conservation targets and understanding water supply and demand to maintain future water availability (De Loë et al 2001).…”

Integrated water resources management (IWRM) is described as a holistic approach to manage water efficiently, equitably, and sustainably. This paper presents a case study where cooperative strategy building among diverse stakeholders (researchers, potato farmers, and government regulators) resulted in significant water conservation for the on-farm washing of potatoes on a large potato operation (31% reduction per unit of potatoes sold). Water was reduced by applying modified IWRM methods, including (i) goal setting, where common goals with all three parties were outlined; (ii) initial assessment, where farm water use was monitored in detail for one year; (iii) cooperative strategy building, where monitoring results were presented and potential water-use reduction strategies were brainstormed; (iv) implementation, where strategies were put into place on the farm; and (v) final assessment, where water use was monitored for a second year, after conservation strategies were in place, and the efficacy of the strategies was determined. This case study demonstrates the value of IWRM, through cooperation among researchers, farmers, and the regulators, for improving water management in agriculture.

“…The current debate has been on finding ways to minimize the amount of water used in the agriculture sector by using adequate agronomic and irrigation practices that conserve water, but do not undermine crop water requirements (Loë et al, 2001;Yihun, 2015). The system of rice intensification (SRI) has been identified as an on-farm water management practice that increases both land and water productivity at a relatively low cost while also conserving the environment (Stoop et al, 2002;Uphoff, 2006).…”

This study was conducted to evaluate farmers‟ appropriation of the system of rice intensification (SRI) in an informal irrigation scheme in northern Tanzania. Understanding the integration and performance of SRI in the local rice farming will assist in short and long-term planning and allocation of available resources. First, a survey was conducted to explore farmers‟ adjustments of SRI principles. Second, yield and water productivity of the integrated system was assessed by setting up experimental plots in the farmers‟ fields. Four treatments representing farmers‟ adaptations of SRI practices were assessed. One treatment (F1) was continuous flooding while the other three treatments (F2, F3 and F4) were under intermittent irrigation. The yield of 4.8, 8.5, 8.2 and 9.2 tons/ha, and water productivity of 0.15, 0.39, 0.35 and 0.51 Kg/m 3 were obtained for F1, F2, F3 and F4, respectively. Water-saving under SRI was 34.3%, 28.9%, and 45.1% for F2, F3 and F4, respectively. The figures are comparable to those reported under full SRI, which is in the range 20% to 60%. The highest yield (9.2 tons/ha), water productivity (0.51 Kg/m 3 ) and water-saving (45.1%) was obtained in F4 involving one seedling 15 days old transplanted at 25 x 25 cm. However, this method is not preferred by many farmers due to lack of supporting infrastructure. Hence, F2 involving two seedlings 21 days old planted at 20 x 20 cm with intermittent irrigation is recommended for this area as it ensures a sufficient number of plants, relatively higher yields and a reduced considerable amount of irrigation water.
