“…There are multifaceted impacts of regional socio‐economic aspects on agriculture – and ultimately irrigators’ water trading decision‐making (Crase and Merton 2013; Wheeler et al ., 2020b). Indeed, the history of the placement of irrigation districts has also played a role in driving the influence of water trading on regional socio‐economics.…”

“…Wheeler et al . (2020b) analysed the drivers of MDB farm exit decisions at the statistical local area level from 1991 to 2011, and found statistically significant associations between increased net farm exits and decreased commodity output prices, increased urbanisation, higher temperatures and higher unemployment. However, the study also found no statistically significant link between net farm exit and changes in irrigation water diversions and water trade movements.…”

“…At the same time, many rural MDB communities have faced substantial socio‐economic changes – resulting in a reduction of jobs, services, farm numbers and population sizes. This is attributed to changes in agricultural production, labour market restructuring and a withdrawal of public and private sector services (Alston 2004; Wheeler, Xu and Zuo 2020), although this result is not homogenous across all areas (Pritchard and McManus 2000; Wheeler et al . 2018).…”

The southern Murray-Darling Basin of Australia has the world's largest and most sophisticated water markets. However, there has been little study on the drivers of permanent and temporary water market movements within local areas, or the substitution effects between groundwater and surface-water extraction over time. This topic is important as it is often claimed that water market trade patterns (especially selling large amounts of permanent water) are associated with rural decline. This study uses random-effects tobit panel models to investigate the association of regional and spatial socio-economic characteristics with temporary and permanent southern Murray-Darling Basin water market trade, using a broker panel database at postcode level from 2010/11 to 2013/14. Overall, results suggest there is no statistical significant evidence that more disadvantaged communities sold larger amounts of permanent water. Permanent water selling was statistically more likely to be associated with other spatial and land productivity characteristics, while temporary water market trade volumes were more related to water scarcity factors. In addition, there was evidence to suggest a substitution effect between rural areas selling higher volumes of permanent water and using higher volumes of groundwater.

“…Approximately 90% of the Australian cotton (Gossypium hirsutum L.) crop is grown in the Murray-Darling Basin (MDB), particularly in northern New South Wales (NSW) and southern Queensland (QLD) in both irrigated and dryland cropping systems [1][2][3]. Approximately 83% of cotton grown within the MDB is irrigated, with the remaining 27% being dryland [4][5][6]. Irrigation is used to mitigate the risk of inadequate rainfall, particularly during the vegetative stages of cotton growth [7].…”

Impacts of Effects of Deficit Irrigation Strategy on Water Use Efficiency and Yield in Cotton under Different Irrigation Systems

Irrigated cotton (Gossypium hirsutum L.) growers in the Murray-Darling Basin (MDB) of Australia, are challenged by limited water availability. This modelling-study aimed to determine if deficit irrigation (DI) practices can potentially improve water use efficiency (WUE) for furrow irrigation (FI), overhead sprinkler irrigation (OSI) and subsurface drip irrigation (SDI) systems. We validated the Agricultural Production System sIMulator (APSIM) against observed cotton lint yield and crop biomass accumulation for different management practices. The model achieved concordance correlation coefficients of 0.93 and 0.82 against observed cotton crop biomass accumulation and lint yields, respectively. The model was then applied to evaluate the impacts of different levels of DI on lint yield, WUE across cotton growing locations in the MDB (Goondiwindi, Moree, Narrabri, and Warren), during the period from 1977 to 2017. The different levels of DI for the FI system were no irrigation, full irrigation (TF) and irrigated one out of four, one out of three, one out of two, two out of three and two out of four TF events. For the OSI and SDI systems, DI levels were no irrigation, TF, 20% of TF, 40% of TF, 60% of TF and 80% of TF. Lint yield was maximised under the OSI and SDI systems for most locations by applying 80% of TF. However; modelling identified that WUE was maximised at 60% of full irrigation for OSI and SDI systems. These results suggest there are significant gains in agronomic performance to be gained through the application of DI practices with these systems. For FI, DI had no benefit in terms of increasing yield, while DI showed marginal gains in terms of WUE in some situations. This result is due to the greater exposure to periodic water deficit stress that occurred when DI practices were applied by an FI system. The results suggest that in the northern MDB, water savings could be realised for cotton production under both OSI and SDI systems if DI were adopted to a limited extent, depending on location and irrigation system.

Water security in sub‐Saharan Africa: Understanding the status of sustainable development goal 6

et al. 2021

The world is nearing the 2030 target‐year by which sustainable development goals (SDGs) should be achieved. While other developing regions seem to be making progress toward achieving SDG6, sub‐Saharan Africa (SSA) is lagging behind significantly, particularly with regard to access to water supply and sanitation (WSS). As a result, most studies evaluating progress toward the achievement of water security SDGs in SSA have focused on WSS while the rest of the SDG6 targets have received scant attention, often using fragmented or incomplete evidence. Here, we fill this knowledge gap by conducting a comprehensive assessment of the status of SDG6 in all 48 countries in SSA. We provide a review of the progress made, the challenges affecting each SDG6 target and examine the different political, socioeconomic, and environmental factors with potential to undermine the achievement of SDG6 in the region. Our review clearly demonstrates that it is likely that most countries may not achieve water security by 2030. The complex nature of the challenges and factors impeding the achievement of water security in SSA outlined here suggests that a holistic intervention involving local, national, and international stakeholders and the research community is urgently needed to address SDG6 if the 2030 target date is to be met. Approaches to enhance water security may equally consider: (a) underpinning peace and security in SSA and (b) the commitment of more financial resources by donors particularly during this period of COVID‐19 pandemic.
