Abstract

Any effort to improve irrigation water availability has an advantage in the crop production processes. Small-scale rainwater harvesting technologies like Charco-dams (Malambo) in Swahili (the language used by most the Tanzanians) are among the interventions proven to overcome agricultural water shortage.

Opportunities and challenges for small-scale aquaculture in southern Chile: The stakeholders’ perspective

Submitted by Petra Hansson on

We identify and explore the potential opportunities and challenges for promoting and expanding small-scale aquaculture (SSA) as an additional income-generating activity for coastal communities in southern Chile. Based on a conceptual model of SSA adoption decisions, we conducted field key informant semistructured interviews with stakeholders in the Los Lagos region and in the regional capital city, Puerto Montt. We conducted a qualitative analysis of the interviews to identify potential resource users’ perceptions of current SSA opportunities.

Economics of Marine Protected Areas: Assessing the Literature for Marine Protected Area Network Expansions

Submitted by Petra Hansson on
EfD Authors:

Marine protected areas (MPAs) provide both conservation and economic benefits. Recent international conservation actors have called for a dramatic increase in the area of MPAs from almost 8% to 30% of marine area by 2030 in a policy called 30X30. Both the economics and conservation science literature consider MPA decisions and MPA impact, although the economics literature focuses on fishery economic outcomes. This review uses an optimization framework for MPA decisions as a lens through which to evaluate the economics literature on MPAs in the context of the 30X30 expansion decisions.
