Relationships between Agricultural policies and Environmental Effects in Japan: An Environmental-Economic Integrated Model Approach AgEcon
Sasaki, Hiroki.
This study investigates the optimal agricultural land use allocation and nitrogen application to a representative Japanese farm. The site-specific nature of numerous agri-environmental issues necessitates analysis at a disaggregated level in order to capture the underlying heterogeneity of agricultural productivity and environmental sensitivity across different parcels of land. This study adopts an integrated approach—a decision-making economic model for representative farms is combined with a stylized site-specific biophysical model, which quantifies the impact of different policy instruments on agricultural production practices and on multiple environmental effects. This model estimates the government budget outlays and social welfare, which require...

Decaffeinated? Situation, Trends, and Prospects for Smallholder Coffee Production in Rwanda AgEcon
Loveridge, Scott; Nyarwaya, Jean Baptiste; Shingiro, Emmanuel.
Most Rwandan coffee is currently grown and processed the same way it was a decade ago. Consequently, Rwanda’s coffee production and marketing system has not been able to keep up with changes in the global market for high quality coffee. Given world market gluts of relatively poor quality coffee, Rwanda is now exporting a product that fetches low prices. Despite the challenges in coffee marketing and production, coffee remains one of Rwanda’s most important official sources of foreign exchange and the drop in production is of major concern to both the public and private sectors. In an effort to assist decision makers in the coffee sector better understand factors affecting farmers’ production decisions and their attitudes about coffee, the FSRP fielded a...

The Adoption and Impact of Improved Maize and Land Management Technologies in Uganda AgEcon
Sserunkuuma, Dick.
In spite of the fact that the Ugandan National Agricultural Research System has developed and released several production-enhancing technologies over a century, yields of most major crops at the farm level have been low. Given that about 80 percent of Uganda’s labor force is employed in agriculture, the scope for sustainable poverty reduction in Uganda depends very much on improving agricultural productivity. It is in this context, this paper examines why there has been poor adoption of production-enhancing technologies in the production of maize, which is a major crop in Uganda and what the impacts of the exiting production environment are on factor payments. This study reveals that farmers do not pay proper attention to soil fertility management, which...

Distribution of Benefits and Adoption of Bt Cotton in Pakistan: Ex-ante Analysis AgEcon
Nazli, Hina; Sarker, Rakhal; Meilke, Karl D.; Orden, David.
This poster presents the potential impact of Bt cotton adoption in Pakistan. The size and distribution of economic benefits from the commercial adoption of Bt cotton in Pakistan are examined under four hypothetical scenarios. The adjusted economic surplus model is used to measure total benefits and their distribution between producers, consumers and technology innovators. To account for uncertainty in key parameters, the stochastic simulation techniques is applied. The results show that the total net benefits of adopting Bt cotton in Pakistan are large. As a result of increase in production, farmers get considerable benefits despite a decline in price. The share of benefits to innovators is small. The results indicate that the total cost of adopting latest...

EVALUATING THE RETURNS TO VARIABLE RATE NITROGEN APPLICATION AgEcon
Roberts, Roland K.; English, Burton C.; Mahajanashetti, S.B..
Potential benefits of variable rate nitrogen application are illustrated and information needs identified. Lower costs of precision farming services, higher crop prices, and greater divergence in yield response potentials across management zones reduce the spatial variability required for profitable variable rate application. Information needs include identification and measurement of management zones within a field and estimation of management zone yield response functions, crop and input prices, and the cost of precision farming services.
Tipo: Journal Article Palavras-chave: Production economics; Management zones; Nitrogen; Precision farming; Spatial break-even variability proportions; Variable rate applications; Yield response variability; Crop Production/Industries.

Assessment of the Farm Level Agronomic and Financial Benefits of the Magoye Ripper in Maize and Cotton Production in Southern and Eastern Provinces AgEcon
Kabwe, Stephen; Donovan, Cynthia; Samazaka, David.
This research focuses on the performance in the Magoye ripper in maize and cotton production in Eastern and Southern Provinces during the 2004/2005 productions year. Findings include the following: In maize production, the ripper enabled higher yields compared to traditional animal ploughing, by increasing the effectiveness of nitrogen fertilizer applications, resulting in net profits per hectare of ZK575,800 in Eastern Province and ZK93,800 in Southern Province; In cotton, the input applications and size of fields were the most important determinants of yield, and the ripper had no significant individual effect. Farmers using the ripper indicated that it helped conserve water, enabled early land preparation and early planting; and Farmers not using their...

Antidumping and Market Power in the Agriculture Sector, with a Special Case Study of the Fresh Tomato Industry AgEcon
Baylis, Katherine R..
In this article we highlight the anticompetitive nature of antidumping (AD) legislation. Antidumping legislation was set up to protect domestic firms from predatory pricing by foreign firms. We argue that protecting highly concentrated industries drastically reduces competition at home. In cases where the industry consists only of one or two firms, import restriction may breed monopolies at the expense of domestic consumers. This article looks at cases filed by the agriculture sector, and at the market concentration of industries in this sector, to illustrate the above possibility. We study the case of fresh tomatoes in detail to further demonstrate the anticompetitive nature of AD legislation. We show the effect of AD legislation on imports, as well as...

Incentive to reduce crop trait durability AgEcon
Ambec, Stefan; Langinier, Corinne; Lemarie, Stephane.
Inbred line seed producers face competition from their own consumers: farmers who save part of their harvest can costly self-produce. To reduce this competition, seed producers can switch to non-durable hybrid seed production. In a two-period model, we investigate what is the impact of crop durability on self-production, pricing strategies and switching decision. We first study the pricing decisions and switching decisions of an inbred line seed monopoly. Then, we analyze how the monopoly's behavior is affected by the entry of a hybrid seed producer. We also examine how the introduction of royalties on farmers who self-produce improves efficiency. Our main finding is that, for some constellation of costs, an inbred line seed monopoly has an incentive to...

Modelling Forestry in Dynamic General Equilibrium AgEcon
Lennox, James A.; Turner, James A.; Daigneault, Adam J.; Jhunjhnuwala, K..
Adequately representing dynamic characteristics of land use change and forestry in computable general equilibrium models is challenging but essential if modellers are to provide credible assessments of policies that directly or indirectly influence these phenomena. In this paper, we show how a dynamic representation of planted or naturally regenerating forests may be integrated within a neoclassical, intertemporal general equilibrium model. We demonstrate the application of such a model to assess the impacts of including forestry within a hypothetical emissions trading scheme in the US, showing the resulting changes in land use and increases in the optimal rotation length.
