This paper examines the effects of compliance with developed country pesticide standards (DC-PS) on pesticide-related health costs and morbidity of developing country fresh vegetable growers. DC-PS require that farmers i) only use approved pesticides (usually less toxic to humans than ones used before), ii) apply pesticides only when pest scouting reveals the need to do so, and iii) handle, use, store and dispose off pesticides in ways that do not pose health threats to farm workers and farm family members. This paper uses survey regression to estimate a model of health costs of pesticide exposure (based on cost of illness approach) and survey poisson regression to estimate a model for use of protective devices. It finds that compliance with DC-PS reduces... |

Changing orchard sprayer technology and rising pesticide costs to fruit growers raise the need to analyze the profitability of alternative sprayer investments. This study analyzes investments in four orchard sprayers for use in Michigan apple production: an air blast sprayer, a tower boom sprayer, a tower boom sprayer equipped with electronic sensors that activate spray nozzles when foliage is detected, and an air curtain sprayer that targets spray with a layer of forced air. Assuming equal pest control efficacy, the study calculates the annualized net present cost per acre of owning and operating each sprayer for ten years using a baseline discount rate of 10 percent over 200 acres of semi-dwarf apple trees. The analysis found the annualized net... |

Data on agricultural and natural resource management typically have spatial patterns related to the landscapes from which they came. Consequently, econometric models designed to explain the determinants of humans' natural resource management practices or their outcomes often have spatial structure that can bring bias or inefficiency to parameter estimates. Although econometric tools are available to correct for spatial structure, such tools are largely lacking for use with discrete dependent variable models. While one obvious solution would be to develop the necessary tools, an alternative is to identify conditions under which spatial dependency can be managed effectively without formal spatial autoregressive models. This study examines conditions... |

Land degradation in sub-Saharan Africa reduces the land's potential productivity through soil erosion, nutrient depletion, soil moisture stress, deforestation and overgrazing. Efforts to reverse land degradation require an understanding of why it takes place and what factors govern farmers' willingness to invest in land conservation. These factors differ importantly between private and public lands. This study synthesizes results from analyses of the technological and institutional factors determining the adoption of natural resource conservation at both the household and the community levels in the northern Ethiopian region of Tigray. Using 1995-96 data from 250 Tigray farm household interviews, it first examines private land management, focusing on 1)... |

Implementation of the Food Quality Protection Act (FQPA) is fraught with difficulty due to the divergent perspectives and demands of stakeholders in the process. In "Part I: Agricultural Producer Concerns," the authors reviewed the concerns of food producers about potential FQPA threats to farm profitability, international competitiveness, consumer perceptions, and the development of pest resistance to remaining pesticides. Fortunately, lessons from past environmental policy and economic theory offer useful principles for how to implement the FQPA. This paper, "Part II: Implementation Alternatives and Strategies" addresses ways to accommodate producer concerns while meeting the policy mandate of reducing risk from pesticide exposure, especially for... |

In response to stagnating yields and mounting pest problems, Michigan potato growers are investigating ways to bring manure and cover crops back into potato production systems. The alternative systems bring benefits and costs for monetary net returns, the variability of net returns, and environmental impacts. This paper reviews the likely yield and biological system effects of alternative potato production systems that incorporate manure and cover crops. After briefly considering research designs for gathering experimental versus farm field data, it reviews four economic analysis methods for evaluating alternative systems. All methods are illustrated with examples. First, for evaluating comparative average profitability, it reviews a) enterprise... |

A long term whole farm analysis comparing conventional and low-input farming systems is reviewed. A computational error led to the mistaken conclusion that conventional farming with government programs is less preferred by risk-averse farmers than the low input alternative. The greater income variance of conventional agriculture need not make it less preferred provided a higher mean income sufficiently offsets the higher variance. |
