| Resumen: |
The emerging large-scale production units (LSPUs) have become increasingly important in Chinese agricultural production and rural transformation due to rapid industrialization and urbanization. Based on household and plot-level data from Jiangsu and Jiangxi Provinces in China, this study provides insights into the farming systems of these LSPUs and examines how contract type, as a proxy for land tenure security, impacts on the production unit’s soil-improving investments. Results from the two-stage control function approach show that the written nature of contracts positively affects the application of organic fertilizer and green manure on rented-in plots. Descriptive analysis also confirms the collateralization effect of contract type by showing that plots that are used as collateral for credit are characterized by written contracts. Policies facilitating LSPUs’ access to farmland with more formal contracts may therefore play an important role in improving soil quality and land productivity. |

| Resumen: |
The effectiveness of adaptation strategies is crucial for reducing the costs of climate change. Using plot-level data from a specifically designed survey conducted in Pakistan, we investigate the productive benefits for farmers who adapt to climate change. The impact of implementing on-farm adaptation strategies is estimated separately for two staple crops: wheat and rice. We employ propensity score matching and endogenous switching regressions to account for the possibility that farmers self-select into adaptation. Estimated productivity gains are positive and significant for rice farmers who adapted, but negligible for wheat. Counterfactual gains for non-adapters were significantly positive, which is potentially a sign of transactions costs to adaptation. Other factors associated with adaptation were formal credit and extension, underscoring the importance of addressing institutional and informational constraints that inhibit farmers from improving their farming practices. The findings provide evidence for the Pakistani Planning and Development Department’s ongoing assessment of climate-related agricultural losses. |

| Resumen: |
Las heladas tardías han sido siempre una condicionante de la fecha a la que se inciia la siembra de maíces tempranos. Presentamos un trabajo que evaluó el impacto de un corte de emparejamiento sobre el rendimiento de un maíz helado en el ambiente de Balcarce |
