8 flocks of Ojinegra ewes (n=5634) were studied during a productive cycle (2007-2008) in Teruel (Spain), a low-mountain dry and harsh area. Ojinegra ewes belong to a local breed, of small-medium size, reared under a semi-extensive system of management. Throughout three seasons (autumn, winter and spring) weight and BCS of 5634 ewes at lambing and weaning were recorded and 5786 lambs were weighed fortnightly form birth to weaning. Season had a significant (p>0.01) effect on weight and BCS of ewes and on lambs average daily gain.

After a previous description of pasture utilization in Sierra de Guara Natural Park, eight sheep farms were selected for a study of the relationships between farming systems and land use at the farm level. They were representative cases obtained from a previous typology based on criteria of technical management and pasture use. After a detailed description of the system, a SWOT analysis was carried out in order to identify the main factors involved in farm continuity and sustainability of land use.

The mountain farmers operate on whole of animals (flocks, herds, working herds) copying models coming surely from the beginning of domestication.

The importance of water scarcity in irrigated agriculture in Spain provides the rationale for this paper, which analyses and evaluates the risk of water shortage on the economic result of this kind of agriculture. The main objective is to monitor this risk on a real-time basis. For this aim, we first estimated a number of regression models that explain irrigated agricultural productivity based on crop price indices, a time trend and water availability. These models, which correct for auto-correlation, yield good explanatory power.

Economic valuation of irrigation water is done through the use of production functions for the case of the olive grove. In order to do so the integration of an agronomic model (based on the production function) and an economic model linked to the profitability of the crop (the ratio of revenue and operating costs) in the area under study is proposed. The study case encompasses the Guadalbullon River Sub-basin area, belonging to the Guadalquivir River Hydrologic Demarcation (Southern Spain).
