| 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. |

| 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. |

Market participation, on-farm crop diversity and household welfare: micro-evidence from Kenya |

| Resumen: |
This paper examines determinants of output and input market participation. It employs propensity score matching techniques to evaluate the impact of market participation on pigeonpea diversity and household welfare, using cross-sectional data of 333 households from Kenya. Results show that input and output market participation decisions are quite distinct. Output market participation is influenced by household demographics, farm size and radio ownership, while input market participation is determined by farm size, bicycle ownership and access to a salaried income. The findings reveal a positive and significant impact of output market participation on pigeonpea diversity, while input market participation had a negative and significant impact on diversity. The results indicate that output market participants have significantly higher food security status than non-participants, in line with the general findings of the literature. However, no significant impact is found between indicators of household welfare and input market participation. |

When could payments for environmental services benefit the poor? |

| Resumen: |
Since modification of agricultural production choices in developing countries often provides positive environmental externalities to people in developed countries, payment for environmental services (PES) has become an important topic in the context of economic development and poverty reduction. We consider two broad categories of PES programs, land-diversion programs, where lands are diverted from agriculture to other uses, and working-land programs, where agricultural production activities are modified to achieve environmental objectives. PES programs are generally good for landowners. The distribution of land and land quality is critical in determining poverty impacts. Where ES and agricultural productivity are negatively correlated and the poor own lands of low agricultural quality, they stand to gain from PES programs. Consumers and wage laborers may lose where food supply is inelastic and programs reduce labor demand. Working-land programs may have better distributional effects than diversion programs. |

Poverty, risk, and the supply of soil carbon sequestration |

| Resumen: |
We explore poor farmers’ incentives to adopt production systems that increase soil carbon sequestration, focusing on the impact of risk. A dynamic optimization model of conservation agriculture adoption is presented, where farmers optimize over expected utility of profits from agriculture and carbon sequestration. Adoption impacts on agricultural productivity are modeled as a combination of the technological effects of the new system, and productivity effects of changes in soil carbon on agricultural output. Comparative static results indicate increases in soil carbon sequestration price and the discount rate have unambiguous impacts on equilibrium soil carbon levels; the former leading to higher, and the latter to lower, carbon levels. Increases in the price of agricultural output and risk aversion have ambiguous impacts, depending on the relative strength of the productivity and technology effects. The paper concludes with a discussion of designing soil carbon payment mechanisms to benefit low income farmers. |
