“…For agronomists, IWUE is determined by rainfall, irrigation, soil moisture and crop evapotranspiration (ET) requirement. Such definitions mainly focus on engineering and agronomic techniques, and are measured through field experiments that do not consider water as an economic good [11,12]. In order to evaluate the economic performance of water in socio-economic system, water has been considered a primary input in combination with other inputs (land, labor, capital, etc.).…”

Abstract:Water has become increasingly scarce in northwestern China due to climate change, economic growth and burgeoning population. Improving agriculture water use efficiency is of strategic significance in promoting socio-economic water productivity for arid and semi-arid inland river basins. Based on the household-level data collected in Zhangye City, which is located in the middle reaches of Heihe River Basin (HRB) in northwestern China, irrigation water use efficiency (IWUE) of maize is estimated based on stochastic frontier analysis. The impacts of influential factors, especially the participatory irrigation management (PIM) through water user associations (WUAs), on IWUE were further examined. Results show that the estimated average Technical efficiency (TE) and IWUE of maize production are 0.74 and 0.24, respectively. The participation level in irrigation management is very low, with only 40% of the respondents participating in WUA meetings. In addition, most have a relatively superficial understanding of the roles and management scheme of WUAs. Empirical results show that though significantly positive, the magnitude of the impact of PIM on IWUE is relatively small. Households that participated in WUA meetings achieved only 0.002% higher IWUEs than those have never participated in. WUAs are not operating with their designed objectives. Consequently, reform of the traditional management form of WUAs to make them more transparent, fair, and extensively participated in among farmers is in urgently need. In addition, we also find that water price, source of irrigation water, irrigation technology adoption and famers' education level and farming experience also have significant positive impacts on IWUE.

“…The Sefficiency framework [26] was used to evaluate the performance of WUSs, by modelling drivers, such as climate change and population growth, and their influences on water resources. A brief description of the methodology is provided here, further details can be found in [10,39]. The structure given in Figure 2 is unchangeable from project to project and shows the water flow path types (WaTs) used to define the terminology presented (with the Usefulness Criterion of Equation (2)) upon which the indicators, such as in Equation (1), can be developed.…”

“…The Kano River basin (KRB) of Northern Nigeria (Figure 1), a semi-arid region, has irrigation and urban water supply using a significant part of the available water resources. The use of water by these sectors is already causing water shortage that significantly affects the livelihoods of downstream , and therefore has an essential role in the efficient use of water resources in the basin [10]. Thus, concerns about water scarcity in KRB should pay more attention to these sectors.…”

“…Thus, concerns about water scarcity in KRB should pay more attention to these sectors. The main challenges related to water resources in the basin are degradation in water quality, poor multi-sectoral coordination, water allocation problems, poor stakeholders' participation and growing competition for water among upstream and downstream areas and different sectors [10]. The unilateral decision by the Kano state government to construct a hydropower station at Tiga dam is an example of uncoordinated surface water uses which raises concern for water availability for KRIP (Kano River Irrigation Project), a major irrigation area in the Kano River basin.…”

Improving the performance of water use systems (WUSs) is essential for addressing the pressure on water resources for sustainability. Despite the potential impacts of population growth and global warming especially in semi-arid regions, the knowledge and understanding of WUSs and impacts of those main drivers of change on their performance are not available in the Kano River basin (KRB). This paper assesses these impacts on the performance of KRB, using the new and innovative Sefficiency (sustainable efficiency) framework, which incorporates quantity, quality, and beneficial aspects of water use in a comprehensive and systemic manner. We found that performance of the WUSs is sensitive to population growth and global warming under the scenarios considered. Kano River is relatively less sensitive to global warming impacts, while high population growth is dominant. Moreover, their combined effect will result in a reduction of downstream water by 70% and potential demands will far exceed the available supply by 2050. It is recommended that efficient management of water regarding the qualitative as well as quantitative aspects is very critical in KRB. This study can be regarded as the first step, and future studies may adopt the described methodology and can benefit from smart technologies, e.g., sensors and remote sensing.

The complexity of irrigation systems and the need to adapt them to uncertainties requires developing approaches to synthesize their performances. This paper reviews performance assessment and indicators for agricultural water systems. It is aimed at finding various methods and indices used for irrigation performance assessment and standard classes for their characterization. The global application of the metrics was also documented. Adopting a systematic review approach, peer‐reviewed journal articles published in the English language in the last two decades (1 March 2001 to 31 December 2020) were surveyed. Case studies were presented demonstrating the application of the indicators. The study revealed a lack of standardization and the use of a wide range of indicators among others, and recommended representing certain indicators as single. However, this review considered one indicator as the best. Suggestions for further studies were made.
