This article reports on a survey of ranch owners in high amenity areas in southwestern Montana that have experienced marked ownership change over the last two decades. Specifically, we focus on findings from a set of questions targeting water resource and riparian area management. After reviewing the results, we consider how new owners may be managing water resources differently than longtime owners and what the ecological implications of this shift in management might be for Montana's prized wild fisheries.

For some fifteen years, dairy cattle farming has been considerably developing in various parts of the Andes. Milk is transformed into cheese or sold fresh, giving rural families a regular income which secures their food supply. The stock-rearing practices in these Andean dairying systems are unrecognized and are often considered, wrongly, as underperforming and inadequate.

In this paper we investigate the potential production and implications of a global biofuels industry. We develop alternative approaches to consistently introduce land as an economic factor input and in physical terms into a computable general equilibrium framework. The approach allows us to parameterize biomass production consistent with agro-engineering information on yields and a "second generation" cellulosic biomass conversion technology.

Selective grazing can modify the productive capacity of rangelands by reducing competitiveness of productive, palatable species and increasing the composition of more grazing-resistant species. A grazing system (season-long and short-duration rotational grazing) x stocking rate (light: 16 steers·80 ha-1, moderate: 4 steers·12 ha-1, and heavy: 4 steers·9 ha-1) study was initiated in 1982 on northern mixed-grass prairie. Here, we report on the final 16 years of this study (1991-2006). Spring (April+May+June) precipitation explained at least 54% of the variation in peak standing crop.
