Erosion mitigation in the Waikato District,New Zealand: economic implications for agriculture 下载免费PDF全文
Soil erosion, in its various forms, is caused or aggravated by agricultural activities. Mitigation of surface erosion comprises the construction of shelterbelts, fencing, riparian buffering, and stock reduction. Mitigation of mass‐movement erosion, in turn, takes the form of spaced planting of trees to maintain a persistent, healthy, and complete ground cover. In this article, we assess the economic implications to agriculture of the adoption of mitigation alternatives for erosion control in the Waikato District, New Zealand. The Waikato District presents a spatial pattern of erosion that affects profitability of dairy, and sheep and beef enterprises. We use the Universal Soil Loss Equation and the New Zealand Empirical Erosion Model to estimate erosion figures that are then fed into an economic‐focused, nonlinear, partial equilibrium mathematical programming model of New Zealand land use. Different scenarios are constructed for surface and mass‐movement soil erosion targets ranging from 0% to 50% below baseline levels. We find that achieving surface erosion targets is more expensive than mass‐movement targets, and results in different responses in regional‐level costs, land use, enterprise net revenue, and adoption of mitigation alternatives. 相似文献

Designing and evaluating sustainable development pathways for semi‐subsistence crop–livestock systems: lessons from Kenya 下载免费PDF全文
Achieving the Sustainable Development Goals (SDGs) in African agriculture requires a better understanding why high levels of poverty and resource degradation persist in African agriculture despite decades of policy interventions and development projects. In this article, we hypothesize that policies need to account for the key features of the semi‐subsistence crop–livestock systems (CLS) in the region to become effective. The semi‐subsistence CLS are characterized by a high degree of biophysical and economic heterogeneity and a complex, diversified production system involving a combination of subsistence and cash crops with livestock. We investigated the potential for interventions proposed by the Government of Kenya to meet the SDGs by 2030. The analysis uses an integrated modeling approach designed to deal with the key features of these systems. A strategy that stimulates rural development, increases farm size to a sustainable level, and reduces distortions and inefficiencies in input and output markets could lead to a sustainable development pathway and achieve the SDGs for rural households dependent on CLS. 相似文献

Extreme interannual variability of precipitation within Ethiopia is not uncommon, inducing droughts or floods and often creating serious repercussions on agricultural and nonagricultural commodities. A dynamic climate module is integrated into an economy‐wide model containing a detailed zonal level agricultural structure. This coupled climate‐economic model is used to evaluate the effects of climate variability on prospective irrigation and infrastructure investment strategies, and the ensuing country‐wide economy. The linkages between the dynamic climate module and the economic model are created by the introduction of a climate‐yield factor (CYF), defined at the crop level and varied across Ethiopian zones. Nine sets of variable climate (VC) data are processed by the coupled model, generating stochastic wet and dry shocks, producing an ensemble of potential economic prediction indicators. Analysis of gross domestic product and poverty rate reveal a significant overestimation of the country's future welfare under all investment strategies when climate variability is ignored. The coupled model ensemble is further utilized for risk assessment to guide Ethiopian policy and planning. 相似文献

Assessing cost‐effectiveness when environmental benefits are bundled: agricultural water management in Great Barrier Reef catchments 下载免费PDF全文
John Rolfe Jill Windle Kevin McCosker Adam Northey 《The Australian journal of agricultural and resource economics》2018,62(3):373-393
Using economic analysis to prioritise improvements in environmental conditions is particularly difficult when multiple benefits are involved. This includes ‘bundling’ issues in agricultural pollution management, where a change in management action or farming systems generates multiple improvements, such as reductions in more than one pollutant. In this study, we conceptualise and compare two different approaches to analysing cost‐effectiveness when varying bundles of benefits are generated for a single project investment. Each approach requires data to be transformed in some way to allow the analysis to proceed. The index approach requires the transformation on the benefits side so that the effects of multiple pollutant changes can be combined into a measure for each project which can then be compared to costs. By comparison, the disaggregation approach requires the transformation on the costs side where costs for each project have to be apportioned across the different pollutants involved. The paper provides novel insights with an application to agricultural water quality improvements into the Great Barrier Reef in Australia, demonstrating that while both approaches are effective in prioritising projects by cost‐effectiveness, the disaggregation approach provides more insightful results and values that may be relevant for use as upper value guidelines in future project selection. 相似文献

Reducing dependence on fossil fuels by decreasing energy consumption is a common environmental policy. One mechanism used to achieve this is to encourage increased energy efficiency. However, improving efficiency may have an opposing effect and cause an increase in energy consumption if the intensity of use changes. This phenomenon is known as the rebound effect. We estimate direct rebound effects for energy use in Australia based on both aggregate residential energy use data and on household energy expenditure data. Our approach implements a new methodology developed by Hunt and Ryan (2014, Catching on the rebound: Why price elasticities are generally inappropriate measures of rebound effects. Surrey Energy Economics Discussion Paper Series SEEDS 148; 2015, Energy Economics 50, 273) that explicitly relates energy service use with energy source demand and directly incorporates measures of efficiency changes. The results indicate that the rebound effect is relatively high for energy use by Australian households. Due to the unique nature of our household data set, we can examine the influence of demographic and housing characteristics. We find that low‐income households and households with vulnerable members have the largest rebound effects. The relatively large rebound effects found here suggest that consumers gain from efficiency by improved energy services, and thus, policy targeting energy efficiency is not likely to be successful at reducing energy consumption. 相似文献

The impacts of adopting agricultural innovation and technology are widely examined. This paper synthesises 154 studies, which yielded a total of 600 estimates of the impact of adopting agricultural innovation and technology on production, social and economic outcomes. Using meta‐regression analysis, the empirical results show that the reported impact of adopting agricultural innovation and technology rises significantly over time, notwithstanding a significant publication bias. Whether studies find significant impacts of adopting agricultural innovation and technology depends on the use of experimental research designs, parametric method, endogenous switching regression and region. Our results show a large bias in the literature towards agricultural innovations and technologies that focus on high‐yielding varieties and thus, neglect other forms of complementary innovations and technologies. 相似文献

Cost‐reflective pricing: empirical insights into irrigators’ preferences for water tariffs 下载免费PDF全文
Bethany Cooper Lin Crase John M. Rose 《The Australian journal of agricultural and resource economics》2018,62(2):256-278
Using prices to improve the efficiency with which water resources are allocated is now widely accepted in principle if somewhat difficult to achieve in practice. Whilst there are some technical difficulties associated with full‐cost recovery in irrigation, the lack of political will to tackle reform remains a significant impediment. This article reports the results of an empirical investigation into farmers’ preferences for changes to water prices and tariff structures. We conclude that some of the preferences of farmers are conducive to price reform. We also find evidence that public subsidy of infrastructure in irrigation is not always aligned with the preferences of farmers. 相似文献

Socio‐economic transitions and everyday life changes in the rural world: Pyrenean households and their contemporary economic history 下载免费PDF全文
This article focuses on understanding rural life and how agrarian everyday life changes as a consequence of the radical socio‐economic transformations that, across the world, have accompanied rural communities in their transition from economies of subsistence to industrial production, and, in some areas, from there to providers of service to the tourism‐oriented leisure economy. In the last century in the Alt Urgell District (Spanish Pyrenees), many communities went from a production model based on subsistence farming and livestock breeding first to a specialization in milk production and later to tourism. The industrialization of milk production, the radical transformation of the scale of their operations, and the monetization of life transformed the identity and structure of these communities. The subsequent transformation of many of these farms to accommodate the leisure industry changed the shape of these households again. This paper reflects on how science, governance, commodification, and technology played a role on the transformation of the rural mountain areas, their people, and their everyday life. 相似文献

The Effect of Cross‐Border Mergers and Acquisitions on Earnings Quality: Evidence from China 下载免费PDF全文
Despite the fruitful research on the motives and outcomes of cross‐border mergers and acquisitions (M&As) of Chinese multinational corporations (MNCs), there has been scant research on the impact of cross‐border M&As on corporate governance. In this article, we fill the research gap by exploring whether cross‐border M&As may lead to an improvement in corporate governance of Chinese acquirers. In particular, we examine the impact of cross‐border M&As on earnings quality of Chinese MNCs. We find that the acquisition of a target firm from a developed country leads to a significant improvement on the acquirer's earnings quality. In comparison, the acquisition of a target from an emerging market does not have such an impact. Our results are robust to various corporate governance measures, alternative econometric methods, and controls of relevant firm characteristics and macroeconomic variables. Finally, we show that the effect of cross‐border M&As on earnings quality is more pronounced in non‐state‐owned enterprises (non‐SOEs) that have conducted large M&A deals. Our article offers new insight to the international business literature on latecomer perspective and liability of foreignness. © 2016 Wiley Periodicals, Inc. 相似文献
