Advisory to the farmers

Increased rainfall across the western central parts of the country has led to progressively saturated soils, while the southeastern part has experienced reduced rainfall and a decline in soil moisture conditions during the first dekad of July. As forecasted that rainfall will increase in the western part of the country and decrease in the southeast, farmers, agricultural stakeholders, and agro-industries are advised to take the following precautions to minimize potential impacts on agricultural activities:

Farmers located in the wester part of the country are strongly advised to take additional precautionary measures in their farming activities. This is due to the expected continuation of heavy rainfall, which may lead to rising river levels and possible flooding of nearby farmlands and access roads. Such conditions could disrupt farm operations, damage crops, and make transportation of agricultural products difficult. Therefore, farmers are encouraged to closely monitor local weather updates, secure farm inputs and harvested produce, and avoid crossing flooded roads or waterways during this period.

Farmers are also strongly encouraged to regularly monitor their crops, as persistent rainfall in the west and reduction in the southeast may create favorable conditions for increased pest infestations across farmlands. In the event of any pest outbreaks, farmers should promptly take appropriate pest control measures, including the use of recommended agricultural practices and approved pesticides where necessary, to minimize crop damage and yield losses. Note: It is also recommended to seek advice from extinction officer before taking these measures.

¨ Livestock producers are encouraged to keep their animals in well-protected shelters, as increased rainfall can contribute to the spread of infectious animal diseases. Prolonged wet conditions may also increase the incidence of respiratory illnesses and other health complications. However, extended dry periods can expose livestock to heat stress, water shortages, reduced feed availability, and an increased risk of disease. Therefore, livestock producers are advised to closely monitor their animals for signs of illness, heat stress, dehydration, or any abnormal behavior that may indicate disease or distress. If any symptoms are observed, prompt veterinary intervention and appropriate management measures should be taken to safeguard animal health, welfare, and productivity.

Vegetable producers are advice to continued their farming activities upland and are strongly encouraged to properly design and lay out their fields, including the use of appropriate drainage and soil conservation practices, to minimize the risk of soil erosion and nutrient loss during period of heavy rainfall events.

General Precautions:

Stay informed about weather updates through the Liberia Meteorological Service website (https://meteoliberia.com).

Work closely with local agricultural extension officers for region-specific advice on crop and livestock management.
