The use and exploitation of natural resources is generally structured by institutions, especially by property institutions. The main objective of this paper is to present a diachronic analysis of the institutionalization of common land property in Portugal. The several types of ownership may be largely explained by common land history. We intend to draw an outline of the emergence, evolution and transition of common land from the late nineteenth century to the present day, using the matrix proposed by Heller.

This study identifies farm‐specific and market factors affecting the adoption of herbicides and the level of herbicide use by rice farmers in the Philippines. This requires the application of a modified version of Heckman's two‐step method to estimate a random‐effects double‐hurdle model for unbalanced panel data.

In this article, we analyze the impact of land fragmentation, farm size, land ownership and crop diversity on farm profit and efficiency of 90 groundwater irrigated farms in the hard rock areas of South India. As we hypothesize that these variables may impact both, farm profit and efficiency in alternative ways, we develop four different stochastic frontier and inefficiency effect models by shifting some of these variables from the inefficiency model into the profit function.

We summarized all known historical and contemporary data on the geographic distribution of Etheostoma raneyi (Yazoo Darter), a range-restricted endemic in the Little Tallahatchie and Yocona rivers (upper Yazoo River basin), MS. We identified federal and state land ownership in relation to the darter's distribution and provided quantitative estimates of abundance of the species.

Namatala wetland near the town of Mbale in the Eastern region of Uganda is a papyrus wetland that is subject to conversion for agriculture (mainly rice farming) and pollution by wastewater. The main goal of this study was to analyze the ecosystem functions and services of Namatala wetland and their drivers of change, and to suggest directions for sustainable use. Data on climate, hydrology, water quality, population and land use were collected. Stakeholder workshops were organized at national and local levels to identify stakeholder interests in the wetland and conflicts.

In this research, we evaluated the intent of engaged private forest landowners to supply woody biomass for bioenergy production. The study was conducted in a U.S. state (Kentucky) where private individuals own a majority (78%) of the state's forest resources. Intent of family forest owners was measured using a mail-based survey. We used the Theory of Planned Behavior to model factors that affect landowner intention, and we tested the effect of educational materials on participates' reported intent.

Beginning with the premise that sovereignty may be most constructively contemplated not as a definable object or objective but instead as a process, this article examines counter-mapping as a way for contemporary indigenous citizens to “do” sovereignty. It surveys three Anishinaabe/Ojibwe communities’ recent use of geographical techniques to communicate their own territorial claims and counter the competing claims of others.

The aim of this paper is to shed new light on urban common property systems. We deal with urban commons in relation to urban green-space management, referring to them as urban green commons. Applying a property-rights analytic perspective, we synthesize information on urban green commons from three case-study regions in Sweden, Germany, and South Africa, and elaborate on their role for biodiversity conservation in urban settings, with a focus on business sites. Cases cover both formally established types of urban green commons and bottom-up emerged community-managed habitats.

La investigación buscó explicar cómo, a través de los siglos, la noción y las características de la propiedad, que actualmente leyes y manuales nos delimitan con meridiana claridad, no fue estática ni congelada en el tiempo.

El trabajo es un análisis de sociología histórica comparada que, siguiendo la propuesta de B. Moore, se pregunta por el rol de las organizaciones indígenas y campesinas en el proceso de modernización de la sociedad ecuatoriana. En una perspectiva histórica establece los lazos entre el avance del capitalismo en el campo y las transformaciones socioeconómicas que dan paso, por un lado al debilitamiento de las viejas élites terratenientes, y por otro lado a la emergencia de los movimientos indígenas y campesinos.

Cambodia is currently experiencing profound processes of rural change, driven by an emerging trend of large-scale land deals. This article discusses potential future pathways by analyzing two contrasting visions and realities of land use: the aim of the governmental elites to foster surplus-producing rural areas for overall economic growth, employment creation and ultimately poverty reduction, and the attempts of smallholders to maintain and create livelihoods based on largely self-sufficient rural systems.

Production of commodities for global markets is an increasingly important factor of tropical deforestation, taking over smallholders subsistence farming. Measures to reduce deforestation and convert shifting cultivation systems towards permanent crops have recently been strengthened in several countries. But these changes have variable environmental and social impacts, including on ethnic minorities. In Vietnam, although a forest transition - i.e.
