| Título: | Impacts of off-farm employment on groundwater irrigation in North China |

| Resumen: | This study examines the relationship between groundwater irrigation and off-farm employment with a set of household level data collected in North China. The results provide evidence that off-farm employment reduces both time spent on irrigation in terms of total hours of irrigation and the amount of groundwater pumped. However, these effects have not resulted in losses of crop production. In fact, water productivity measured as output value produced per m3 of groundwater pumped is higher among households with off-farm employment. These seemingly contradictory findings are explained by the increased use of water-saving technologies such as furrow irrigation, underground pipes and/or lined canals. These technologies reduce seepage losses during the conveyance of groundwater as well as during irrigation of the fields. As a result, less groundwater needs to be pumped to achieve the same level of groundwater irrigation application rate in the field. |

| Título: | Do roads lead to grassland degradation or restoration? A case study in Inner Mongolia, China |

| Resumen: | We use satellite remote sensing data of grassland cover in Inner Mongolia, China to test whether the existence of and the size of roads in 1995 is associated with the nature of the grassland in 2000 and/or if it affects the rate of change of the grassland between 1995 and 2000. The regression results show that the impact of roads on grassland cover depends on the nature of the resource. When the grassland is composed of relatively high quality grassland, roads lead to degradation, whereas when grassland resources are sparse, access to a road results in the restoration of the resource. |

| Título: | Irrigation water demand and implications for water pricing policy in rural China |
| Fuente: | Environment and Development Economics. v.15, n.3. Beijer Institute of Ecological Economics; Royal Swedish Academy of Sciences |
| Páginas: | pp. 293-319 |
| Año: | June 2010 |
| Resumen: | The goal of this paper is to analyze whether reforming groundwater pricing has the potential to encourage water conservation and assess its impacts on crop production and producer income in rural China. Household-level water demands are estimated so that adjustments at both the intensive and extensive margins are captured. The results show that a large gap exists between the cost of water and the value of water to producers. Simulation analysis shows that reforming water pricing can induce water savings. However, the price of water needs to be raised to a relatively high level. We also find that the value-based policy is more effective than the cost-based policy since it generates larger water savings, given the same increase in the average price of water. While raising the price of water negatively affects crop production and crop income, higher water prices do not adversely affect the distribution of household income |

| Título: | Water management reform and the choice of contractual form in China |
| Fuente: | Environment and Development Economics. v.13, n.2. Beijer Institute of Ecological Economics; Royal Swedish Academy of Sciences |
| Páginas: | pp. 171-200 |
| Año: | 2008 |
| Resumen: | This paper explains the puzzling fact that in organizing the management of surface water, village leaders have provided incentives to canal managers in some areas, but not in all. Our study indicates that the optimal contractual choice depends on the relative abilities of the leader and the manager, the design of the cultivated land, the characteristics of the canal system and the opportunity costs of the leader and the pool of managerial candidates. The unifying mechanism is the relative change in the ability of the leader and manager to perform the unmarketable activities that are needed to provide irrigation services. |
