The Murray-Darling Basin (MDB) Plan in Australia legislated in 2012 represents the largest recovery of water, from consumptive use to environmental use in the world – with the aim of restoring rivers and ecosystems back to health. To date, although billions of dollars have been spent, the Plan's water recovery targets have not been achieved and will not meet their original target dates for full recovery, with governments needing to continue to make difficult water policy choices and trade-offs. This study explores a survey of Australian public preferences for five different water reallocation options in the MDB (and methods to be used for recovery) and identifies individual characteristics associated with various policy options. Almost a quarter of those surveyed did not support further water recovery; 17% favoured recovering water to current goals only; 22% favoured recovering environmental water beyond current goals; while 38% favoured recovering both environmental and cultural water beyond current goals. For those wanting further recovery, a third preferred using irrigation infrastructure subsidies as the main method, while the majority favoured buying water directly back from irrigators (either through voluntary buyback or compulsory acquisition). Trust levels, location, age, climate change perception and gender all played a part in influencing respondent preferences for various water recovery options.
Irrigation has been promoted as a strategy to reduce poverty and improve livelihoods in southern Africa. Households' livelihood strategies within small-scale irrigation schemes have become increasingly complex and diversified. Strategies consist of farm income from rain-fed and irrigated cropping as well as livestock and an increasing dependence on off-farm income. The success of these strategies depends on the household's ability to make decisions about how to utilize its' financial, labour, land and water resources. This study explores the dynamics of decision-making in households on-farm household income within six small-scale irrigation schemes, across three southern African countries. Household survey data (n = 402) was analyzed using ordered probit and ordinary least squares regression. Focus group discussions and field observations provided qualitative data on decision-making in the six schemes. We found strong support for the notion that decision-making dynamics strongly influence total household income. Households make trade-offs between irrigation, dryland, livestock and off-farm work when they allocate their labour resources to maximize household income; as opposed to maximizing the income from any individual component of their livelihood strategy, such as irrigation. Combined with the impact of the small plot size of irrigated land, this is likely to result in sub-optimal benefits from expensive investments in irrigation infrastructure. Policy-makers must consider this when developing and implementing new policies.
Abstract Communities in Australia's Murray‐Darling Basin face the challenge of trying to achieve social, economic, and environmental sustainability; but experience entrenched conflict about the best way to achieve a sustainable future, especially for small rural communities. Integral ecology is a philosophical concept that seeks to address community, economic, social, and environmental sustainability simultaneously. Its inclusive processes are designed to reduce stakeholder conflict. However, to date the application of the integral ecology concept has been largely qualitative in nature. This study developed a quantitative integral ecology framework, and applied this framework to a case study of the Riverina, in the Murray‐Darling Basin. Seventy‐seven community‐focused initiatives were assessed, ranked, and quantified. The majority of the community‐focused ranked initiatives did not exhibit all aspects of integral ecology. Initiatives typically prioritized either (1) economic and community development or (2) environmental health; rarely both together. The integral ecology framework developed here enables recommendations on future community initiatives and may provide a pathway for community leaders and other policy‐makers to more readily apply integral ecology objectives. Further research refining the framework's operationalization, application and implementation to a wider‐scale may enhance communities' capacity to develop and grow sustainably.
Water markets have been used by Australian irrigators as a way to reduce risk and uncertainty in times of low water allocations and rainfall. However, little is known about how irrigators’ bidding trading behavior in water markets compares to other markets, nor is it known what role uncertainty and a lack of water in a variable and changing climate plays in influencing behavior. This paper studies irrigator behavior in Victorian water markets over a decade (a time period that included a severe drought). In particular, it studies the evidence for price clustering (when water bids/offers end mostly around particular numbers), a common phenomenon present in other established markets. We found that clustering in bid/offer prices in Victorian water allocation markets was influenced by uncertainty and strategic behavior. Water traders evaluate the costs and benefits of clustering and act according to their risk aversion levels. Water market buyer clustering behavior was mostly explained by increased market uncertainty (in particular, hotter and drier conditions), while seller-clustering behavior is mostly explained by strategic behavioral factors which evaluate the costs and benefits of clustering.
The mechanisms linking growth and inequality are critical for poverty reduction, yet they remain poorly understood at the micro level, as current knowledge is dominated by country-wide studies. This article evaluates farm income growth and changes in inequality among five smallholder irrigation communities in Mozambique, Tanzania and Zimbabwe. Over the period of study, the poorest sections of the population became better-off. Over an income growth spell, at low levels of growth, relative inequality increases, but it starts to drop as growth rises beyond a certain rate. Thus, careful design is required to ensure that pro-growth strategies also become inequality-reducing.
Future water policy strategies to address low environmental flows in the River Murray in Australia may include the continued development of programmes for irrigators to donate water. We identify and control for the interdependence between irrigators' recognition of the need for increased flows and their stated intention to donate seasonal allocations over time. The increased uncertainty of seasonal water allocations played one of the largest roles in negatively influencing both recognition and intention. An increase in the opportunity cost of water donation over time was negatively associated with intention. The identification of significant willingness to donate allocations supports the movement towards a more adaptive water policy approach.
