About the campaign

• Pastoralist communities live a nomadic lifestyle, grazing animals on open-access pastures and migrating with them in response to seasonal variations. Livestock and livestock products serve as their primary sources of income and food.
  
  However, changing weather patterns induced by climate change are threatening the livelihoods of these communities in the eastern Horn of Africa. The region is experiencing one of the worst droughts which already resulted in the loss of over 7 million livestock and put millions at risk of starvation in Ethiopia, Kenya, and Somalia.
  
  The goal of this campaign is to assess vegetation health using the Normalized Difference Vegetation Index (NDVI) following the October-November-December 2024 rainy season and disburse funds to participating pastoralists if the NDVI at the end of this period suggests insufficient vegetation to support livestock during the subsequent dry season. The target cover amount of $75 per pastoralist intends to subsidize the provision of food for one livestock animal over a period of six months.
  
  DIVA Donate is a collaborative initiative between DIVA Technologies and Fortune Credit, utilizing blockchain technology to provide effictive and efficient disaster relief to vulnerable communities affected by climate change. This campaign represents the fourth iteration in the series dedicated to supporting Kenyan pastoralists.

• Pastoralists in Kajiado (Kenyan county)

The pasture condition is assessed using an indicator called NDVI (Normalized Difference Vegetation Index). The NDVI is a widely-used metric for quantifying the health and density of vegetation using sensor data. It serves as a reasonable metric for assessing drought as vegetation density generally correlates with rainfall patterns.

For this campaign, the NDVI as at 31 December 2024 within the eVIIRS dataset for Kajiado County, Kenya, as published on the USGS FEWS NET Early Warning System website, is used. This value will be reported via the Tellor Protocol on 10 January 2025, with a +1 shift applied for technical reasons. The chosen dataset offers a smoothed NDVI timeseries that corrects low-quality observations caused by clouds or other atmospheric contamination. The donation release profile has been derived by analyzing historical NDVI trends during drought years (2014, 2017, 2022), ensuring a tailored response to drought conditions.

The amount released to pastoralists depends on the NDVI value at the end of the campaign period and the underlying donation profile. Below, we illustrate the percentage of contributed funds released in specific sample scenarios, based on the underlying donation profile.

• 100% - if the NDVI is at or below 1.45
• 50% - if the NDVI is at 1.50
• 0% - if the NDVI is at or above 1.52
