| 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. |

| The paper analyzes the relationship between the allocation of labor and land of the households, the number of crops grown and the number of income sources of the households with different types of shocks and risks. It uses the data from the first phase of the household survey in three provinces of Central of Vietnam, conducted within the scope of the DFG research project “Impact of shocks on the vulnerability to poverty: consequences for development of emerging Southeast Asian economies”. The results suggest that the households diversify their portfolio (labor and land) into different income generating activities in order to cope with shocks. Among the different types of shocks and risks, agriculture and economic shocks and risks are the main factors to... |

| Economic analysis of chemical pesticide use has shown that the interactions between plants, pests, damage control technology and state of the ecosystem are important variables to be considered. Hence, a bio-economic model was developed for the assessment of Bt variety and pesticide-based control strategies of the cotton bollworm in China. The model simulates plant growth, the dynamics of pest populations and of natural enemies. The model predictions are used as major inputs for a stochastic partial budgeting procedure of alternative control strategies. Results show that: (1) productivity effects of Bt varieties and pesticide use depend on the action of natural control agents, and (2) the profitability of damage control measures increases with the severity... |

| 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... |

| This paper presents an application of a two and three stages difference in differences model to measure environmental and economic impacts of Farmer Field School on crop and pest management practices of rice in Thailand. Panel data from 241 farm households were collected three times over a period of four years in five riceproducing provinces of Thailand. Data included socio-economic data describing household and farm characteristics, rice input and output data including detailed accounts of pesticide use and other pest management practices and farmers' knowledge of crop management and agro ecosystem factors. Using the concept of environmental impact quotient parameters on the health and environmental consequences of a change in pesticide use was computed.... |

| 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... |
