“…Interestingly, the results highlight contrasting effects generated by livelihood assets on livelihood strategies and livelihood outcomes. Consistently with previous studies (i.e., Deressa et al, 2009;Bahinipati and Venkatachalam, 2015;Malaiarasan et al, 2021), the current study shows that the presence of animals on the farm (physical capital), the extension of cultivated land (natural capital) and the access to informal sources of credit (financial capital) positively influence the adoption of a strategy focused on varietal diversification of rice and wheat, although the effect of these assets is negative on the yield change (livelihood outcome). Female-headed households are less likely to increase genetic diversity of rice in their fields, in fact they are associated with negative yield changes, even if they show positive levels of recovery capacity.…”

There is evidence that in many situations the use of a diverse set of two or more crop varieties in the field has benefits for production. The benefits of varietal diversification include lower crop disease incidence, higher productivity, and lower yield variability. Targeted interventions could increase varietal diversity where smallholder farmers lack the knowledge and access to seeds needed to diversify their varieties. Innovations based on crowdsourced citizen science make it possible to involve a large number of households in farmer participatory varietal selection. This study analyses varietal diversification in Bihar, India, focusing on the effects of the largest citizen science-based intervention to date, involving 25,000 farmers and 47,000 plots * seasons. The study examines if an increase in the varietal diversity of major staple crops, namely wheat and rice, under real farming conditions contributed to: (1) crop productivity and (2) the ability of households to recover from agricultural production shocks. We used the Rural Household Multi-Indicator Survey (RHoMIS) as a survey tool for rapid characterization of households and the sustainable rural livelihoods framework to understand the potential multiple interactions that are activated within the system by the intervention. We found that an increase in varietal diversification produced livelihood benefits in terms of crop productivity and the ability of households to recover from the occurrence agricultural shocks. Finally, outcomes highlight the effectiveness of development programmes aimed at strengthening rural livelihoods through participatory approaches and use of local crop varietal diversity.

“…The environmental attitudes questions were found not to influence CD in preliminary analyses, and not used in any subsequent analysis. Total income and non-agricultural income were coded as dummy variables (similar to [55]), as the different levels represented answers with differing amounts of uncertainty (e.g., RMB 10,000-25,000 vs. RMB 50,000-100,000). Village was also added as a fixed effect.…”

Encouraging crop diversity could be a “win–win” for farmers and biodiversity conservation, if having a variety of crops produces the heterogeneity that supports biodiversity, and if multiple crops decrease the risk of farmers to losses due to pests, climatic events or market fluctuations, without strongly reducing their incomes. However, data on the factors that influence the decision to plant multiple crops, and how that affects profit, are needed, especially for East Asia, where these questions have been little studied. We distributed a questionnaire on these issues to 301 farmers in 35 villages in an agricultural area close to the city of Nanning in Guangxi, south China. Crop diversity increased with land size and closeness to the city. We detected no relationship between profit variability and crop diversity, but farmers with greater crop diversity and more land were more profitable, a result driven by several rarely planted but lucrative types of crops. Crop diversity can be a focus for policy to improve farmers’ livelihoods; these policies need to encourage farmers with little land to form cooperatives. Further research is needed to understand the effect of crop diversity on profit variability, and in areas closer to protected areas where biodiversity is higher.
