State of index-based crop insurance services in East Africa: Findings from a scoping study to establish the state of index-based crop insurance services in Kenya, Tanzania and Ugan... por Osumba, Joab J.L., Recha, John W.M., Demissie, Teferi Dejene, Shilomboleni, Helena, Radeny, Maren A.O., Solomon, Dawit

“…The insurance avoids costs related to assessing and validating policyholder losses and minimizes moral hazard and adverse selection problems, given that policyholders cannot affect the distribution of payouts ex ante and the historical distribution of the index is observable to both the insurer and the policyholder (Miranda and Farrin 2012). For these reasons, index-based insurance offers a potentially cost-effective means of managing smallholder production risks and has the potential to strengthen resilience by cushioning the risk of losses and debt. …”

Institutionalization of REDD+ MRV in Indonesia, Peru, and Tanzania: progress and implications por Ochieng, R.M., Arts, B., Brockhaus, Maria, Visseren-Hamakers, I.J.

“…Nevertheless, the extent to which MRV has been institutionalized varies across countries, with Indonesia experiencing “deep” institutionalization, Peru “shallow-intermediate” institutionalization, and Tanzania “intermediate-deep” institutionalization. We explore possible reasons for and consequences of differences in extent of institutionalization of MRV across countries.…”
