Land tenure security (LTS) is important for achieving many sustainable development goals but its influence on forest cover is mixed. The uncertain relationship between LTS and forests is driven, in part, by the moderating influence of other drivers of deforestation. In this paper we illustrate this complex relationship between LTS and forest cover for individual private landholders in the Colombian Amazon. We use household surveys and econometric analysis with matching techniques to examine whether formal land titles and perceptions of LTS influence forest cover.

Highlights

• Friendship and field proximity are key determinants to information flow on new on-farm water management tools in Ethiopia.
• Knowledge on field size and seed variety are key indicators of productive friendships in irrigation schemes.
• Friendship and field proximity facilitate information flow on irrigation duration even among farmers without the tools.

Abstract

CONTEXT

This study evaluates the Vietnamese shrimp farming industry through a Triple Bottom Line (TBL) perspective, using the Aquaculture Performance Indicators (API) to assess social, economic, and environmental performance. Over the past 25 years, Vietnamese shrimp farming has grown rapidly and diversified into four systems: Extensive, Semi-intensive, Intensive, and Super-intensive, and data is collected for all these systems.

Estimating the cost to society from a ton of CO 2, termed the social cost of carbon (SCC), requires connecting a model of the climate system with a representation of the economic and social effects of changes in climate, and the aggregation of diverse, uncertain impacts across both time and space. A growing literature has examined the effect of fundamental structural elements of the models supporting SCC calculations. This work has accumulated in a piecemeal fashion, leaving their relative importance unclear.
