Última Comparative Costs and Conservation Policies for the Survival of the Oranutan and Other Species: Includes an Example AgEcon Tisdell, Clement A.; Swarna Nantha, Hemanath. The extent to which conservation is feasible is constrained by budgets and the financial sacrifice stakeholders are willing to bear. Therefore a possible objective for conserving a species is to minimise the cost of achieving that stated aim. For example, if a minimum viable population (MVP) of a species is to be conserved, the size and type of habitats reserved for this could be selected to minimise cost. This requires consideration of the comparative (relative) opportunity costs of reserving different land types for conservation. A general model is developed to demonstrate this and is applied to the case of the orangutan. In the ecological literature, recommendations for reserving different types of land for conservation have been based on comparisons of...

Ano: 2010 URL: http://purl.umn.edu/90466 Computing Opportunity Costs of Growing Local Varieties for On-farm Conservation: Illustrations Using Sorghum Data from Ethiopia AgEcon Wale, Edilegnaw; Mburu, John G.; Estrella, Jaime. The recent shift of emphasis to on-farm conservation is driven by its diverse attractive features - participatory nature, dynamic nature, capacity to maintain not only crop diversity but the knowledge that evolves with it, the chance it offers and the challenge it brings to link conservation with farmers' livelihood. To make it operational, placing incentives and removal of perverse incentives are of critical importance. However, before placing sound incentives compatible to farmers' circumstances, the opportunity costs farmers face when using local varieties of public interest should be understood. This paper empirically examines farmers' opportunity costs of maintaining local varieties of sorghum using a household survey data collected from 198 sorghum...

Ano: 2006 URL: http://purl.umn.edu/25675 Künftige Wettbewerbsfähigkeit der Milchproduktion im Berggebiet Österreichs und der Schweiz AgEcon Kirner, Leopold; Gazzarin, Christian. The mountain areas of Austria and Switzerland are important locations for dairy farming. Owing to natural conditions, the milk in these areas is produced at a considerably higher cost. Nevertheless, structural change in the mountain areas of both countries proceeded at a lower pace than in the plain areas. Milk production in the mountain area of Austria was appreciably expanded. This paper presents a number of attempts to explain these regional shifts, analysing the competitiveness of the farms, as well as the alternatives outside of milk production in the mountain and plain areas of Austria and Switzerland. In addition, we investigate whether milk production in these regions is also capable of holding its ground under future conditions. The on-average...

Ano: 2007 URL: http://purl.umn.edu/96730 Minimising costs of environmental service provision: water-yield, salt-load and biodiversity targets with new tree planting in Simmons Creek Catchment, NSW, a dryland farming/grazing area. AgEcon Nordblom, Thomas L.; Hume, Iain H.; Cresswell, Hamish; Glover, Mark; Hean, Robyn L.; Finlayson, John D.; Wang, Enli. Although dryland farming and grazing have been practiced for over 130 years in the 17,000 ha Simmons Creek catchment without surface salinity problems, the area has been identified as a significant source of salt seepage to Billabong Creek in the NSW Murray catchment. Groundwater movement and salinity levels are spatially heterogenous at Simmons Creek. Groundwater of the upper catchment is relatively fresh and seemingly unconnected with the highly saline groundwater of the lower catchment. However, fresh surface water does flow from the upper to the lower catchment. This spatial diversity provokes the question of where high-water-use forest habitats might be placed to achieve different combinations of environmental services (greater water yield, lower...

Ano: 2007 URL: http://purl.umn.edu/10357 Revealing an Equitable Income Allocation among Dairy Farm Partnerships AgEcon Dressler, Jonathan B.; Tauer, Loren W.. We formulate a method to determine an equitable division of dairy farm partnership income when partners provide unequal amounts of capital, labor, and management and empirically estimate this relationship. New York dairy farm financial data are used within fixed effects and random coefficient panel regression models to reveal a systematic division of dairy farm partnership income among operators’ labor, capital, and management while controlling for heterogeneity arising from differing herd size. Results indicate that controlling for time and heterogeneity across farms due to herd size are important factors when dividing net farm income among unpaid factors of production. Empirical estimates of allocating dairy farm partnership income to equity,...

Ano: 2011 URL: http://purl.umn.edu/102116 The persistence of small dairy farms in Austria from an economic perspective AgEcon Kirner, Leopold; Hambrusch, Josef; Ortner, Karl M.. In the international comparison the structure of milk production in Austria is small scale. The present study presents two theoretical approaches to explain the persistence of small dairy farms in Austria: the opportunity cost principle and the theory of the agricultural household. With regard to the first one it is debatable whether the flat rates really can represent the costs of own production factors in their alternative uses in small enterprises. An illustration on the basis of production cost accounts shows that small dairy farms with no possibilities for the utilization of their own production factors (especially for labour) can cover the production costs by revenues only. Secondly it is argued that agricultural production is likely to continue in...

Ano: 2009 URL: http://purl.umn.edu/52850 Who Pays to Protect Native Vegetation? Costs to Farmers in Moree Plains Shire, New South Wales AgEcon Sinden, Jack A.. The Native Vegetation Conservation Act was introduced on January 1st 1998 to limit the clearing of native grassland and woodland in NSW. The Act has limited clearing and development to crops, has protected biodiversity, and may have enhanced soil and water conservation. But this analysis of the prices paid for land in Moree Plains Shire shows that the Act has reduced land values by some 21 per cent and has already reduced annual incomes by 10 per cent across the whole Shire. This reduction in annual incomes may well reach 18 per cent by 2005. This decrease in income means that farm households in the Shire currently must give up 15.6 per cent of their household income because they must protect native vegetation on their farms. In contrast, urban households...
