To crop production using a linear yield-reduction function specific to a crop (FAO, 1977 FAO, 1979 FAO, 1986).Īdditionally, Verdin and Klaver (2002) and Senay and Verdin (2001) demonstrated a regional implementation of FAO studies have shown that WRSI can be related The availability of water to the crop during a growing season. The spatially explicit water requirement satisfaction index (WRSI1) is an indicator of crop performance based on Product Documentation Water Requirement Satisfaction Index (WRSI) Rangelands Mar-Jul (long rains) (east2).Rangelands Oct-Jan (short rains) (east1).If you are an operational user and rely on historical analysis, you should transfer your historical archive to the CHIRPS – ETos WRSI (when it is available), since the two are not directly compatible. We are currently processing historical data for the CHIRPS – ETos version. However, eventually, the latter (RFE – GDAS version) will be staged at the HTTP links below and will not be readily accessible from our web page. Currently both versions will be available from the web pages. However, Emergency (IPC Phase 4) outcomes will likely persist in Marib through January, given the significant population of displaced households who are highly dependent on assistance.While we are in the process of transforming all our WRSI web products to utilize CHIRPS - ETos, we will continue to produce the RFE - GDAS based WRSI for an indefinite period of time. By November, most of these areas will likely see improvement back to Crisis! (IPC Phase 3!) given increased availability of food and income with the start of the main harvest. Given expectations for reduced assistance, Emergency (IPC Phase 4) outcomes are expected in Hajjah, Marib, Lahj, and Abyan during the agricultural off-season from August to October when access to food and income is seasonally limited.Given the importance of humanitarian assistance for millions of poor households in Yemen-including high dependence among the displaced-millions of households are expected to face food consumption gaps during the projection period despite revised expectations for stable food prices and purchasing power. As such, it is no longer expected that WFP will scale back up to monthly assistance distributions in the projection period. Rather, available information suggests that WFP is engaging local authorities in discussions regarding the continued provision of assistance at recently reduced levels. The WFP is not currently taking steps to resume monthly assistance distributions, contrary to previously communicated plans.Nearly all beneficiaries received rations equivalent to less than 50 percent of total energy needs. In July, WFP provided emergency food assistance to 7.3 million people as part of the fourth cycle of distributions in 2022 to date. Continuous funding shortfalls have led the World Food Programme (WFP) to cut rations and reduce the frequency of food assistance distributions for most beneficiary households in 2022. Last year, when funding was also a concern, 63 percent of the YHRP was funded. As of August 17, only 42 percent of the 2022 Yemen Humanitarian Response Plan (YHRP) was funded.Staple wheat flour prices are now expected to remain generally stable overall, though at significantly above-average levels. As such, shortages of staple wheat flour are no longer expected during the projection period. Importers have procured additional wheat in August following the resumption of Ukrainian exports.Though flooding caused some to miss planting, aboveaverage rainfall in the July to September rainy season is likely to benefit farmers by reducing irrigation costs and improving crop production prospects, particularly in lowland areas. As a result of crop damage, prices of domestically produced foods including vegetables have increased further. ![]() As of August 18, around 36,205 families had been affected, the majority of whom are in displacement sites. After abnormal dryness in the March to May first rainy season, heavy rain since mid-July has caused widespread flash flooding across 18 of Yemen’s 22 governorates, resulting in damage to critical infrastructure, homes, productive assets, and food stocks, with displacement sites worst affected.Early season dryness and recent floods exacerbate food insecurity amid reduced assistance
