| Resumen: |
There is ample evidence that canal systems often fail to reach their design capacity. This study argues that inefficient allocation of water within canals is one cause. This study collects precise measures of farm-level water withdrawals using flow meters in a canal in Pakistan. These data reveal that farmers near the head of the canal get more canal water than farmers near the tail, even accounting for conveyance efficiency. The results suggest that improvements in canal water management would yield efficiency gains for the canal. |

| Resumen: |
Continental-scale economic analysis suggests that changes in climate conditions are associated with lower agricultural net revenue in sub-Saharan Africa. Specific locations, however, may not reflect this overall trend due to variation in baseline climate, soils, and socioeconomic factors that are difficult to model at large scales. The economic effect of changes in climate conditions on agricultural revenue in particular places in sub-Saharan Africa remains largely unknown. To test this effect, we study an area of West Africa with high climate variation over a small geographic area. We find that higher temperatures and precipitation lower agricultural revenues in the more important rainy season but increase revenues in the less important cool, dry season. |

Estimating the value of the reduction in air pollution during the Beijing Olympics |

| Resumen: |
This study estimates the willingness-to-pay (WTP) of Beijing residents in order to maintain the improved air quality experienced during the Olympic Games. A double-bounded contingent valuation method is applied to a survey of 566 Beijing residents. The results indicate that the mean annual WTP per household is between CNY 22,000 and 24,000, and the median WTP is around CNY 1,700. The WTP for this actually experienced improvement is significantly higher than the results from previous hypothetical WTP surveys in China. |

| Resumen: |
This paper measures the impact of climate on Mexican agriculture using a Ricardian analysis. The analysis relies on economic data from 621 individual farms that were collected in 2002. Data on climate, elevation, soils, and distance to nearest city were matched with each farm. The analysis reveals that farmland values in Mexico are sensitive to climate. On average, warmer temperatures reduce land value by 4,000 to 6,000 pesos per degree Celsius. Examining three climate scenarios for 2100, the models predict average losses of between -42 percent to -54 percent of land value in Mexico. As a percent of income, rainfed farms will suffer slightly larger damages than irrigated farms but comparisons between small and large farms are mixed. |

An economic analysis of using crop residues for energy in China |

Environment and Development Economics. v.8, n.3. Beijer Institute of Ecological Economics; Royal Swedish Academy of Sciences |
| Páginas: |
pp. 467-480 |

| Resumen: |
This study examines the economics of using crop residues to replace coal burning for energy in China in order to mitigate carbon emissions. About 60 per cent of the available crop residues are now used by rural households in China to replace coal so that the residues are already making a major contribution to controlling China’s potential carbon emissions. Using the crop residues more efficiently in village or centralized facilities, shifting to crops with more residues, or growing energy crops can all further reduce carbon emissions. However, accounting for the costs of collecting, transporting, drying and storing crop residues and the foregone crop revenue, the study estimates that the marginal cost to remove more carbon emissions with crop residues will be high. |
