HEAT STRESS AND THE START OF YEMEN'S AGRICULTURAL ACTIVITIES
In the second ten-day period of April 2025, the early warning agrometeorological forecast predicts ongoing weather variability with increased precipitation across various Southern Uplands governorates. This could impact current agricultural activities and the development of seasonal crops.
Key Concerns:
Rainfall Conditions: As of the second ten-day period of April 2025, forecasts indicate a slight increase in rainfall amount and distribution in Yemen, especially in the southern elevated governorates. In areas like Ibb, rainfall totals are expected to range from 60 to 100 mm, gradually decreasing in the surrounding regions. This increase could benefit the crop planting phase by enhancing soil moisture and supporting in germination. However, areas lacking rainfall may face challenges, such as disrupted field operations and delays in crop germination.
Rising Temperatures: By mid-April 2025, temperatures are projected to further rise, exceeding 40 degrees Celsius in the desert governorates of Hadramaut and Al Maharah, raising the risk of heat-related hazards. Coastal governorates along the Red Sea, such as Hajjah, Al Hudaydah, and Taizz, are likely to experience minimal risk of elevated temperatures, though they may still exceed seasonal norms (see figure 1 in the PDF). These higher temperatures, along with persistent dry conditions, are expected to increase water stress, which could impact early sown crops and newly transplanted seedlings, potentially offsetting the benefits of rainfall in the Southern Uplands and coastal irrigated areas.
