Bargaining on Ecological Main Structures for Natural Pest Control: Modelling Land Use Regulations as Common Property Management AgEcon
Nuppenau, Ernst-August.
In this paper we argue that the loss of bio-diversity hould be of concern for farmers, though it seems to be of little or no concern to them at the moment. As diversity is a component of nature that controls the growth of pests, a loss of bio-diversity means increased exposure to pests, danger of crop failures and, in the long run, lower average yields and profits. So far farmers buy costly pesticides for compensating the reduction of bio-diversity. We argue that institutional problems are the reason why farmers are not concerned with bio-diversity, and show that under pure private property rights farmers have interest in pesticides and not in bio-diversity as a measure of crop protect because they have perhaps to devote land to the natural eco-system. In...

Curtailing Fertilizer Scarcity and Climate Change; an appraisal of Factors Affecting Organic Materials Use Option in Nigeria’s Agriculture AgEcon
Omotesho, O.A.; Fakayode, S.B.; Tariya, Y..
Global trends nowadays towards long term sustainable crop production is hinged on either supplementing the use of chemical fertilizers with organic materials or a complete use of organic materials. This is more so since substituting chemical fertilizers with organic materials reduces the risks of exposure to ailments that arise on account of synthetic compounds and increases farmers’ gains via reduced soil erosion and carbon emissions and increased bio-diversity. In this vein, the current study investigated organic materials use in Nigeria’s agriculture. Specifically, the study examined availability and use of chemical fertilizer and organic materials substitutes and investigated factors affecting the use of organic materials in the Nigerian food sector....

Measuring the Cost-effectiveness of Conservation Auctions Relative to Alternate Policy Mechanisms AgEcon
White, Benedict; Burton, Michael P..
The principle motivation for using price-discriminating conservation auctions is that they are expected to be significantly more cost-effective than fixed-price mechanisms. This paper measures cost effectiveness for tenders from two rounds of the Auction for Landscape Recovery in Western Australia relative to counterfactual fixed-price mechanisms. If we assume that the bid equals the compliance cost, the auction gives a significant cost saving over fixed-price mechanisms. If instead we assume that bids include an element of rent, fixed-price mechanisms can be more cost effective than the auction. The significance of these results is that a fixed price scheme may achieve a similar level of cost effectiveness to a conservation auction, when one or more...

Preservation of Bio-Diversity, Heterogeneity of Farm Practices and Payments for Cultural Landscapes under Inhomogeneous Natural Conditions AgEcon
Nuppenau, Ernst-August.
The paper explores the question of diversity in agricultural practice as related to bio-diversity and landscape appearance. It starts with the observation that, in the past, diverse natural conditions have considerably impacted on adapted modes of agricultural production, more than today, and that previously performed farm practices were strongly affiliated with specific natural conditions. These practices positively contributed to a motified, diverse and man-made environment which is frequently considered a beautiful landscape. This has changed dramatically. Particularly, where the European countryside is regarded a natural heritage, today, the public seems to be worried about modern farm practices. After the adoption of modern techniques, farmers prefer...
