Across the tropics, development banks and conservation donors are investing millions in property mapping and registration projects to improve accountability for deforestation. An evaluation of the effectiveness and accuracy of existing environmental registries is crucial to assure the success of future efforts. This study presents an evaluation of deforestation and registration behavior in response to one of the largest of these property registration programs to date — the Rural Environmental Registry (CAR) in the Amazonian state of Pará.

Farmland ownership fragmentation is one of the important drivers of land-use changes. It is a process that in its extreme form can essentially limit land management sustainability. Based on a typology of land degradation and its causes, this process is here classified for the first time as an underlying cause which through tenure insecurity causes land degradation in five types (water erosion, wind erosion, soil compaction, reduction of organic matter, and nutrient depletion).

This article explores the role of local particularism in relation to the global interest in urban agriculture (UA).

We wonder whether the poor understanding of UA governance is associated with a public discourse and academic literature that too easily adopt the generic and universally claimed benefits.
