| 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: |
This study evaluates the effects of vegetative soil conservation practices (afforestation and/or bamboo planting) on farm profit and its components, revenue and variable cost. Since farmers self-select themselves as adopters of conservation measures, there could be a problem of selection bias in evaluating their soil conservation practices. We address the selection bias by using propensity score matching. We also check if there exists spatial spillover in adoption of vegetative conservation measures and how it affects matching. We use primary survey data from the Darjeeling district of the Eastern Himalayan region for the year 2013. Our results suggest strong spatial correlation. We find that the propensity score estimated from the spatial model provides better matches than the non-spatial model. While the results show that vegetative soil conservation can lead to significant gains in revenue, it also increases costs so that no significant gains in profit accrue to farmers. |

| Resumen: |
This article investigates whether residents of Mexico City value air quality. Our results suggest that air quality improvement in PM10 is equivalent to a marginal willingness to pay (MWTP) of US$440.31 per property for the period 2006-2013. The corresponding MWTP for PM2.5 is US$880.63, for O3 is US$623.78, and for SO2 is as much as US$2091.50. These estimates are considerably larger in magnitude compared to the few other studies in similar settings. As a percentage of annual household income, these represent 2.44 per cent for PM10, 4.88 per cent for PM2.5, 3.46 per cent for O3 and 11.59 per cent for SO2. Our estimates of land value-pollution elasticities for PM10 (-0.26 and - 0.58) are within range of hedonic estimates for total suspended particulate matter in US cities around the 1970s. The corresponding elasticities range from - 0.55 to - 0.84 for PM2.5, from - 0.06 to - 0.49 for O3 and from - 0.11 to - 0.34 for SO2. |

| Resumen: |
Using remotely sensed land-cover data in 1994 and 2014, and cross-sectional survey data in 2014, this study examines the association between land use and cover change and agricultural productivity in northern Ghana. We document a significant expansion of crop land and settlements (productive use) at the expense of natural vegetation cover. Land areas converted from natural cover to productive use have higher maize yield (0.17 tons per hectare) and harvest value (1,021 Ghanaian Cedi) compared with those converted from bare soil to productive cover. Moreover, areas that were covered by shrubs or savannah in 1994 were more productive in 2014 relative to bare soils in 1994. Although our data do not allow us to establish causality, the evidence suggests the importance of past land-cover conditions in affecting current agricultural performance, especially in resource-stricken settings where conservation and restoration practices are not as common. |
