I. INTRODUCTION

This ten-day alert bulletin n°28 reveals the climatic conditions and climate forecasts developed for the five Agro-ecological zones for the period December 1 to 10, 2019. It also highlights the potential risks and impacts, observable in certain socio-economic sectors in the five agro-ecological zones of Cameroon. This period is characterized by the gradual installation of the Harmattan in the Far North and North Regions and the displacement of the Inter-Tropical Front (ITF) towards the southern part of the country.

medication acting on thermoregulation in the Far North, North and - the beginning of the scarcity of pasture and water resources;

Adama wa regions; - migration of transhumant herders in search of water points and grazing

- Syncope and psychological stress in schools, following the torrid land in the Far North, North and Adamawa regions; heat, especially among asthmatic subjects in the Far North, North - increase in conflicts between herders and farmers over water points in the and Adamawa regions. Far North, North and Adamawa regions.

V. Some recommendations

a) In the health sector It is recommended that we: - raise public awareness to strictly respect basic hygiene and sanitation rules (wash food items, filter drinking water before consumption in households, use latrines, avoid the accumulation of household waste in the vicinity of dwellings, etc.); - sensitize populations in the Far North, North and northern parts of the Adamawa regions to drinks a lot of water and moderate their consumption of alcohol within this period - consume lots of fresh vegetables and meals rich in proteins in the Far North and northern parts of the Adamawa regions; - promote meningitis vaccination campaigns - dress warmly and put on sleeping gear for protection from the cold nights during this period; - ensure appropriate drainage of any standing water; - stay under shelters or in the house (especially between noon and 3 p.m. when it is extremely hot); - take a cold bath before bedtime; - sleep under mosquito nets. b) In the livestock sector - organise livestock vaccination campaigns to prevent epizootic diseases; - raise awareness to promote fodder cultivation for livestock feed and distribution of fodder crops in preparation for the dry season. c) In the agricultural sector - make nurseries for market gardening and caral fields (for off-season millet) under shade; - transplant off-season crops; - make nurseries under the hedges; - set up drip irrigation systems to irrigate plantations and nurseries in need of water in the Far North, North and northern parts of the Adamawa regions; - promote drought-resistant crops and off-season crops in the Far North, North and northern parts of the Adamawa regions; - promote the practice of integrated pest management to control pests of cereals and other crops. d) In the water and energy sector - sensitize the administrations concerned to take into account the climate forecasts developed by ONACC in the planning of water resource management in dams. (e) In the sector of the environment and biodiversity - raise awareness among populations of the risks of conflicts with wildlife species in search of food and water; - raise awareness of the risks of bushfires and their impacts on climate change as a prelude to the upcoming dry season.
