Food-safety Standards and Farmers Health: Evidence from Kenyan’s Export Vegetable Growers
Provedor de dados: 31
Autores: Asfaw,   Solomon; Mithofer,   Dagmar; Waibel,   Hermann.
Limited empirical evidence exists either to confirm or refute the hypotheses that food-safety standards confer a positive external effect on farmers adopting it. This article makes use of health indicators obtained from a random cross-section sample of 439 small-scale export farmers in Kenya to evaluate the impact of EU retailer food-safety standards on producers’ health. Results show average cost of pesticide-related health risks at about 165 KSh and 324 KSh per cropping season for GlobalGAP adopters and non-adopters export producers, respectively. These costs equal 86.4% of the mean household chemical expenditure per cropping season for non-adopters and 39.6% of those adopters. Using instrumental variable econometric techniques we demonstrate that...

EU private agrifood standards in African high-value crops: pesticide use and farm-level productivity
Provedor de dados: 31
Autores: Asfaw,   Solomon; Mithofer,   Dagmar; Waibel,   Hermann.
In parallel with changes in official standards, supermarket chains in Europe have developed prescriptive, production-oriented standards, e.g. the European Union Retailers Produce Working Group for Good Agricultural Practices (GlobalGAP), and are asking their suppliers for produce to be certified according to food-safety and quality standards. There are concerns that the proliferation and enhanced stringency of standards that are imposed by high-income countries can negatively affect the competitiveness of producers in developing countries and impede actors from entering or even remaining in high-value food markets. Yet, in some cases, others argue that such standards can play a positive role, providing the catalyst and incentives for the modernization of...

What Impact Are EU Supermarket Standards Having on Developing Countries Export  of High-Value Horticultural Products? Evidence from Kenya
Provedor de dados: 31
Autores: Asfaw,   Solomon; Mithofer,   Dagmar; Waibel,   Hermann.
European Union (EU) retailers are setting global benchmarks for the production of fresh food, and are asking their suppliers for produce to be certified according to food safety and quality standards. Compliance to these standards for developing countries small-scale producers entail costly investment in variable inputs and long term structures. Limited empirical evidence exists either to refute or confirm the concern that the proliferation and enhanced stringency of these standards marginalize smallholders from global market. This article therefore explores the costs of compliance, factors explaining the smallholder decision to adopt EU private quality standard and the impacts of the standard on farm financial performance. We develop a two-stage standard...

Determinants of Agricultural Technology adoption: the case of improved groundnut varieties in Malawi
Provedor de dados: 31
Autores: Simtowe,   Franklin; Asfaw,   Solomon; Diagne,   Aliou; Shiferaw,   Bekele A.
This paper applies the Average Treatment Effect (ATE) framework on data obtained from a random cross-section sample of 594 farmers in Malawi to document the actual and potential adoption rates of improved groundnut varieties and their determinants conditional on farmers’ awareness of the technology. The fact that not all farmers are exposed to the new technologies makes it difficult to obtain consistent estimates of population adoption rates and their determinants using direct sample estimates and classical adoption models such as probit or tobit. Our approach tries to control for exposure and selection bias in assessing the adoption rate of technology and its determinants. Results indicate that only 26% of the sampled farmers grew at least one of the...

Export Vegetable Production in Kenya under the EurepGAP Standard: Is Large “More Beautiful” than Small?
Provedor de dados: 31
Autores: Mausch,   Kai; Mithofer,   Dagmar; Asfaw,   Solomon; Waibel,   Hermann.
This paper defines three types of typical certified farms in Kenyan export production: smallholder farms, large-scale contracted farms, and exporter-owned farms. It assesses their economic performance, compares the financial cost of compliance with the EurepGAP standard, and analyses transaction costs. Results show that larger farms are not generally performing more efficiently compared to smallholders who implemented the EurepGAP standard. Despite higher monitoring costs as a result of the introduction of standards, smallholder vegetable producers remain an important source for the exporter companies.

Agricultural Technology Adoption and Rural Poverty: Application of an Endogenous Switching Regression for Selected East African Countries
Provedor de dados: 31
Autores: Asfaw,   Solomon; Shiferaw,   Bekele A.
Achieving agricultural growth and development and thereby improving rural household welfare will require increased efforts to provide yield enhancing and natural resources conserving technologies. Agricultural research and technological improvements are therefore crucial to increase agricultural productivity and thereby reduce poverty. However evaluation of the impact of these technologies on rural household welfare have been very limited by lack of appropriate methods and most of previous research has therefore failed to move beyond estimating economic surplus and return to research investment. This paper evaluates the potential impact of adoption of modern agricultural technologies on rural household welfare measured by crop income and consumption...
