Abstract The acronym IPM (integrated pest management) has been around for over 50 years and now not only supposedly guides research extension in management but also markets pesticides, is claimed to be undertaken by many growers, even resonates with public perceptions politicians. Whether or programs are sustainable the longer term under conflicting stresses strains of modern agricultural environment debatable. We analyse three case studies development Australia: citrus central Queensland,...

Abstract A zombie idea is one that has been repeatedly refuted by analysis and evidence, should have died, but clings to life for reasons are difficult understand without further investigation. The perception investments in modern irrigation systems automatically save water constitutes a idea. On face value, most would accept modernizing makes sense: agriculture represents 70% of global withdrawals while physical efficiencies range between 25% 50% worldwide—that is, the entering system never...

Climate change is likely to have substantial effects on irrigated agriculture. Extreme climate events, such as droughts, are become more common. These patterns evident in median projections of for the Murray–Darling Basin Australia. Understanding returns from irrigation involves explicit representation spatial changes natural stocks (i.e., water supply) and their temporal variability frequency drought states nature) active management responses capital represented by mitigation alternative...

It is likely that climate change will be associated with reductions in inflows of water to the Murray–Darling Basin. In this study, we analyse effects Basin using a simulation model incorporates state‐contingent representation uncertainty. The severity impact depends, large measure, on extent which manifested as an increase frequency drought conditions. Adaptation partially offset adverse change.

Abstract Effective management of water resources is a critical policy issue globally. Using framework developed by Turton, and common set characteristics describing key stages demand, we examine the effectiveness isolated technical (e.g., irrigation upgrades) allocative buyback) efficiency for reducing demand to sustainable levels. We base our analysis on Australia's reform context which offers an advanced example applying these levers achieve efficiency. The study motivated appreciation...

The supply of water for irrigation is subject to climatic and policy uncertainty. object the present paper show how linear non‐linear programming models commonly used in modelling problems such as those arising Murray–Darling Basin may be adapted incorporate a state‐contingent representation Estimates showing potential value improved use are also derived.

Using state contingent analysis, we discuss how and why irrigators adapt to alternative water supply signals. Focusing on the timing of allocations, explore inherent differences in demand for by two key irrigation sectors: annual perennial producers. The analysis explores reliability property right bundles reduced allocations across time influence responses Our findings are then extended management strategies could possible future drier types: (i) where an average reduction is experienced;...

This paper presents a conceptual framework for both assessing the role of economic instruments, and reshaping them in order to enhance their contribution goals managing water scarcity. Water management problems stem from mismatch between multitude individual decisions, on one hand, current projected status resources other. Economics can provide valuable incentives that drive design efficient instruments address governance context conflicting interests relevant transaction costs. Yet, such as...

Where we may be aware that a problem exists, but have only an incomplete description of the drivers and/or possible management solutions, will unaware/uncertain about future returns from, and risks to, private public investments in capital (i.e. social, natural, economic, cultural political). This paper explores unawareness/uncertainty by coupling Arrow's states nature approach for dealing with uncertainty Rothschild Stiglitz's exploration inputs increasing risk. results modified Just-Pope...

Theory suggests that the development of common property increases national welfare, and consistent with this thinking Australia's Murray–Darling Basin ( MDB ) Plan uses a approach to recover environmental water rights in interest. Two recovery instruments are used: purchasing (buyback) from farmers, saving by subsidising irrigator adoption technically efficient technology. A moratorium on buyback has focused subsidised technology adoption. Economists argue welfare is maximised via highlight...

Using a survey of the public (n = 2032) and broadacre farmers 351) in South Australia Victoria, Australia, this research compares farmers' concerns regarding acceptability sustainability agricultural operations. A principal component analysis was conducted on responses to 15 statements capturing environmental, social governance issues related agriculture practices perceptions. This revealed three dimensions: (1) animal welfare, greenhouse gas emissions food safety; (2) farm input use; (3)...

Environmental water management is a relatively new discipline, with concepts, practice and institutional mechanisms that are still emerging. The efficient effective use of environmental to maximize benefits, or efficiency , one such emerging concept. Currently, much the focus on allocative efficiency, where objective achieve better balance between consumptive uses in cost‐effective way. However, this may not provide most way manage long term, managers seeking productive (or operational) ....

A project, firm or industry whose activities are accepted by communities and stakeholders is said to have a social licence operate. The importance of increasingly being realized in natural resource industries where project can impose more environmental costs, e.g. pollution, strain on service delivery housing, than they willing accept. However, the conditions that necessary and/or sufficient obtain/maintain unclear. To rectify this gap, global literature review paired with fuzzy-set...
