| Título: | Seed supply in local markets: supporting sustainable use of crop genetic resources |

| Resumen: | This introductory paper summarizes the policy context, methodological approach, and key results from the set of papers contained in this special edition derived from a FAO-led project on seed sourcing in local markets and its farm-level impacts. The introduction provides the conceptual framework used in the papers for considering the relationship between sourcing seed from market and rural household decision-making as well as the effects this has on two key farm outcomes: on-farm diversity and household welfare. Approaches for data collection and study site selection are described, with a focus on how methodological issues were addressed in the different studies. Lastly, the paper summarizes the results of the individual papers and draws broad conclusions and policy implications for promoting the sustainable utilization of crop genetic resources through increasing market access and in a manner that supports agricultural production. |

| Título: | Sowing the seeds of social relations: social capital and agricultural diversity in Hararghe Ethiopia |

| Resumen: | The paper presents an analysis of the role of two forms of social capital - linking and bonding - on two key farm outcomes: on-farm crop diversity and household wellbeing. Where market transactions are limited, social capital is an important household asset for accessing seed and channelling information. The study is set in a drought-prone region of Ethiopia, with high rates of food insecurity and dependency on agriculture for livelihoods. The region is very rich in crop genetic diversity, particularly for sorghum. The data were collected for a production year that experienced a major drought shock. Results of the analysis indicate that social capital is an important determinant of farm level diversity and wellbeing, with opposing effects related to the two different forms of social capital. This suggests possible trade-offs between the two forms of social capital in terms of food security, production and diversity, which need to be considered in planning interventions. |

| Título: | The impact of seed market access and transaction costs on potato biodiversity and yields in Bolivia |
| Fuente: | Environment and Development Economics. v.17, n.5. Beijer Institute of Ecological Economics; Royal Swedish Academy of Sciences |

| Resumen: | Using data from Bolivia, this paper analyzes seed market participation and how transaction costs in these markets influence intracrop biodiversity and the influence of biodiversity on yields. Results indicate that seed market attributes such as distance and market-level biodiversity have a crucial effect on a farmer’s market choice, suggesting that farmers are willing to sacrifice time and income to travel further distances in order to reach markets with a broader range of varieties. This study finds that farmers from this sample who have access to seed markets are more likely to have higher levels of intracrop biodiversity. In addition, for market-integrated farmers, intracrop biodiversity does not seem to have a negative effect on yields, which suggests that improved market access does not threaten biodiversity in contexts with similar characteristics to the study site. |
