- Rural women are an indisputable force behind efforts to conserve and sustainably use biodiversity all over the world, and as such they are critical players in building climate resilience.
- This year, World Food Day calls for action across sectors to make healthy and sustainable diets affordable and accessible to everyone. It is a reminder that without healthy nature and biodiversity, we cannot have quality nutrition, and without quality nutrition we cannot have good health.
- Migratory birds are a critical link in the global web of life, that not only capture our imagination but connect different ecosystems and species.

Forest Planning Yangambi has been the subject of our investigations. It is part of the dense humid forests of the DRC who are not sufficiently known and there is usually no plan for the protection and management. The study focuses on the structure of emergmg and dominant. The objectives were: to study the structure of the emerging anù ùominant in thc- forcst management of INERA-Yangambi, highlighting the emerging recovery of the dominant and,
knowing the relationship that exists between the diameter of crown and DBH by the exponential model and show density per hectare of emerging and dominant. We conducted the data collection by the inventory block an area of 200 acres in the operative permanent INERA / Yangambi. The method involved the inventory, identification, marking, positioning, making DBH, height of stem and total and crown radius. The analysis results are summarized as follows:
• The density of the dominant is 4 stems per hectare and the emerging 2 stems per hectare.
• The species represented in the mainstream are Trilepisium madagascariensis was 7.8%, 7.3%
Pterocarpus soyauxii, Celtis mildbraedi 5.9%, Symphonia globulifera 5.4% and 5.3% Petersianthusmacrocarpum.
• The species represented in the emerging are: Pericopsis elata 20.2%, 10.7% Celtis mildbraedi,
Pterocarpus soyauxii 10.7%, 7.3% madagascariensis Trilepisium Priora oxyphyllum and 6.4%. Basal area of dominant and emergmg IS estimated at 2.47 m2/ha.
• The surface of the crown of the dominant and emerging is estimated at 12.12%.
