Widely occurred woody encroachment in grass-dominated ecosystems has the potential to influence soil organic carbon (SOC) and total nitrogen (TN) pools at local, regional, and global scales. Evaluation of this potential requires assessment of both pool sizes and their spatial patterns. We quantified SOC and TN, their relationships with soil and vegetation attributes, and their spatial scaling along a catena (hill-slope) gradient in the southern Great Plains, USA where woody cover has increased substantially over the past 100 years.

The meaning of land and land policies is diverse and contested across and within local and (inter)national settings. The phrase 'land policy', used to refer to all policies that have anything to do with land, may be convenient, but it masks the actual complexity of issues. Meanwhile, concern for 'pro-poor' land policy has coincided with the mainstream promotion of efficient administration of land policies, leading to the concept of 'land governance'. Such concepts have enriched discussion on land issues, but they also complicate further an already complex terrain.

Overcapacity is a major problem in common-pool resources. Regulators increasingly turn from limited entry to individual transferable use rights to address overcapacity. Using individual vessel data from before and after the introduction of individual harvest rights into a fishery, the paper investigates how characteristics of rights, scale of operations and transition period affect changes in individual and fleet capacity utilisation and excess capacity.
