2.1 技术简介

技术定义:

Index-Based Livestock Insurance (IBLI) is a product that was designed to help protect pastoralists and their livestock against the effects of prolonged forage scarcity. IBLI triggers payment to pastoralists when the forage situation deteriorates to levels considered to be severe, as compared to historical conditions over time.

2.2 技术的详细说明

说明:

In the event of severe seasonal drought, forage and grazing resources are depleted and livestock may die because of starvation. Index Based Livestock Insurance (IBLI) is the technology applied in the provision of forage based livestock (asset) protection insurance. IBLI uses Normalized Difference Vegetation Index (NDVI), a satellite-derived indicator of the amount and vigor of vegetation, based on the observed level of photosynthetic activity (Tucker et al., 2005). NDVI is derived from 10-day composites of 250m filtered eMODIS processed by the United States’ National Aeronautics and Space Administration (NASA) and transformed by The Earth Resources Observation Systems (EROS) Data Center (EDC) of the US Geological Survey (USGS). NDVI data from the AQUA satellite platform are available from July 2002 to present at https://lta.cr.usgs.gov/emodis.

In the case of IBLI, the index is a deviation of cumulative forage availability (ZCumNDVI) in the insured season. It measures forage conditions over a defined time period and compares the observed NDVI over a particular season, with the observed NDVI over a given historical period (e.g. 15 years). A set threshold below which payouts must be made is called the trigger level. Therefore, when the forage situation in a given season is worse than the 20th worst season in the last 15 years, a payout is triggered. In other words, IBLI will compensate if the forage conditions fall below the worst 20th percentile of seasonal pasture levels cumulated over the historical drought seasons in the past 15 years. IBLI therefore uses the satellite-based vegetation index to measure forage availability and to trigger timely payouts to pastoralists based on the costs of providing supplementary feeds to the animals for the specific season that a drought is triggered.

For precision and proper administration each insured county is broken down into smaller units of insurance which are referred to as Unit Areas of Insurance (UAIs). Each UAI represents a geographical area whose forage availability index data are aggregated as one unit for insurance purposes. The identification of the geographic areas that constitute UAIs is a key step in IBLI contract design because the use of average NDVI over insurable units is based on the premise that drought is a covariate shock and that pastoral communities affected in a particular area are deemed to suffer in equal measure.Thus, for accuracy and acceptability, the index should be tightly correlated with forage scarcity and reflect relative conditions on the ground. Also forage access should be relatively homogeneous for herders residing in the same insurable unit. The process of demarcating UAIs is known as clustering. It is done through a combination of active participatory community engagement and scientific methods .

Insured pastoralists are not always paid when there is drought. They are only paid when drought is so severe that the amount of forage falls below the strike level. Insured pastoralists will not receive payments if the forage availability is more than the strike level. This is an annual policy which covers forage availability as measured by satellite Normalized Difference Vegetation Index (NDVI) in up to 2 rainy seasons as per the bimodal rain patterns in Kenya. Pastoralists who do not hold insurance contracts are not covered by under, and therefore do not receive payments, even if they live in the same UAIs as the ones who have insured their livestock.

土地使用者眼中的长处/优势/机会
The use NDVI for forage monitoring in provision of IBLI eliminates the high costs of loss verification which would otherwise be expensive and consuming in the case of vast and remote ASALs of Kenya.

IBLI contract design is based on robust scientific design which is easily verifiable hence boosting trust in the product.

6.8 技术的弱点/缺点/风险及其克服方法

土地使用者认为的弱点/缺点/风险	如何克服它们？
A key concern of index-insurance products is that there might occur variances in perceived loss versus the actual payouts (basis risk)	Proper contract design should be backed with ground truthing efforts together with awareness creation.

编制者或其他关键资源人员认为的弱点/缺点/风险	如何克服它们？
Basis risk is a weakness with IBLI as they could arise differences in perceived level of forage scarcity by the clients,	vis a vis the index trigger level indicated by the NDVI data. Increased precision in contract design alongside proper capacity and awareness creation to the pastoralists can help mitigate this challenge.
