Les grands arbres urbains sont d’excellents filtres pour les polluants urbains et les particules fines. Un arbre peut absorber jusqu’à 150 kg de CO2 par an, séquestrer du carbone et par conséquent, atténuer les changements climatiques Les arbres fournissent des habitats, de la nourriture et une protection pour les plantes et les animaux, augmentant la biodiversité urbaine. Planter des arbres aujourd’hui est essentiel pour les générations futures!

도시에서 큰 나무는 오염물질과 미세먼지를 제거하는데 매우 효과적입니다. 나무 한 그루는 공기중의 이산화탄소를 150kg까지 흡수할 수 있어 기후변화를 완화하는 데 기여할 수 있습니다. 나무들은 식물과 동물에게 서식처와 음식을 제공하고 보호함으로써 도시 생물다양성을 증진시킵니다. 미래 세대를 위해 지금 나무를 심어야 합니다.

Los grandes árboles de las ciudades son excelentes filtros para los contaminantes urbanos y las pequeñas partículas. Un árbol puede absorber hasta 150 kg de CO2 al año, secuestrar carbono y en consecuencia mitigar el cambio climático. Los árboles proporcionan habitat, alimentos y protección a plantas y animales, aumentando la biodiversidad urbana. ¡Plantar árboles hoy es clave para las generaciones futuras!

Büyük kent ağaçları kent kirleticileri ve ince parçacıklar için mükemmel bir süzgeçtir. Bir ağaç yılda 150 kg CO2 tutabilir, karbon depolar ve dolayısıyla iklim değişimini azaltır. Ağaçlar kent biyoçeşitliliğini yükselterek bitki ve hayvanlara yaşam ortamı, gıda ve koruma sağlar. Bugün ağaçlandırma yapmak gelecek kuşaklar için vazgeçilmez !

Большие деревья в городе являются превосходными фильтрами для загрязняющих веществ и мелкодисперсных частиц. Дерево способно поглощать до 150 кг CO2 в год и связывать углерод, играя свою роль в смягчении последствий изменения климата. Деревья являются местом обитания растений и животных, обеспечивая их питанием и защитой, увеличивая городское биоразнообразие. Важно для будущих поколений посадить деревья сегодня!

Gli alberi urbani di grandi dimensioni fungono da eccellente filtro per gli inquinanti urbani e il particolato fine. Un singolo albero può assorbire fino a 150 kg di CO2 all’anno e sequestrare carbonio dall’atmosfera, contribuendo così a mitigare il cambiamento climatico. Gli alberi forniscono habitat, cibo e protezione per piante ed animali, aumentando così la biodiversità urbana. Piantare alberi oggi è indispensabile per il benessere delle generazioni future!

大面积的城市树木是城市污染物和细颗粒物的优秀的过滤器。一棵树每年可以吸收高达150公斤的二氧化碳，截存碳并从而减缓气候变化。树木可以提供栖息地，食物和动植物保护，增加城市中的生物多样性。我们今天种下的树木是后人必不可少的资源！

Crown diameter and tree density were measured in 52 communities in the Sudan-Sahel using satellite imagery to determine the relationships between rainfall and distance from community center to crown size diameter and tree density. As distance from the community center increased, tree density and crown diameter decreased. As rainfall increased, tree density decreased while crown diameter increased. Distance from the community center is a proxy for age since urbanization and our results indicate that older parts of communities show longer and more consistent tree management.

Cities and the people who live in them
account for more than 80 percent of the world's total
greenhouse gas emissions. In addition, more than 80 percent
of the overall annual global costs of adaptation to climate
change are estimated to be borne by urban areas. This issues
brief looks at potential financing opportunities and costs
of mitigation and adaptation in the urban context.
Wide-ranging potential sources for finance for climate

Woodfuels (firewood and charcoal) are
the dominant energy source and the leading forest product
for most developing countries. Representing 60 to 80 percent
of total wood consumption in these nations, woodfuels often
account for 50 to 90 percent of all energy used. Although
woodfuels are widely perceived as cheap and primitive
sources of energy, commercial woodfuel markets are
frequently very large, involve significant levels of

The planning and management of urban forest has become increasingly important as a focus of urban environmental management. The objectives of this study were to analyze the landuse/land cover and to map functional zones of the urban forest in the upper catchment area of Addis Ababa. This study identifies five landuse/land cover types: (i) Eucalyptus–Juniperus dominated forest, (ii) mixed native forest, (iii) built-up areas, (iv) Eucalyptus plantation (v) crop/grazing lands.

Urban agriculture contributes to local
economic development, poverty alleviation, the social
inclusion of the urban poor and women, as well as to the
greening of the city and the productive reuse of urban
wastes. Urban agriculture encompasses a wide variety of
production systems in both urban as well as peri-urban
areas. This study examines the contribution of urban
agriculture to livelihoods, food security, health, and the
