| This paper uses a Translog form to estimate the water distribution cost for an irrigation consortium. The consortium operates under conditions of the under-utilization of facilities; thus, to achieve full cost recovery, water charges must be set at a higher level than efficiency. As a consequence, farmers may decide to reduce their use of the public irrigation service and instead exploit groundwater. The estimated Translog function explains the costs of water services throughout the irrigated area, and identifies items for which pricing does not accentuate the competition between the use of surface water and groundwater. Based on the estimated coefficients, a hypothesis is hence presented for pricing water provided by the consortium. |

| In the agricultural sector, climate change (CC) affects multiple weather variables at different stages of crop cycles. CC may influence the mean level or affect the distribution of events (e.g., rainfall, temperature). This work evaluates the economic impact of CC-related changes in multiple climatic components, and the resulting uncertainty. For this purpose, a three-stage discrete stochastic programming model is used to represents farm sector of an irrigated area of Italy and to examine the influence of CC on rainfall and on maximum temperature. These variables affect the availability of water for agriculture and the water requirements of irrigated crops. The states of nature, and their change, are defined more broadly than in previous analyses; this... |
