Green walls: vertical gardens for green cities
Our cities are becoming increasingly densely populated, leaving little space for greenery. Many people lack gardens, and there’s also a scarcity of green spaces in public areas. This scarcity can have a negative impact on the well-being of the residents of these cities.
Fortunately, in recent years, more efforts have been made to reintroduce greenery into the urban landscape. Balconies and rooftop terraces are being avidly utilized. However, there are also various creative solutions that most people don’t immediately think of. Green walls are a prime example. Beautiful vertical lawns and gardens provide the necessary foliage in the streetscape without taking up much space.
What are green walls?
Many people associate a garden with grass and plants on the ground outdoors, but it’s entirely possible to have a garden against a wall. Green walls are walls where a vertical garden is installed. It’s different from a wall covered with climbing plants. Green walls have a substrate that supports the growth and allows plants to thrive. This also enables beautifully designed vertical gardens.
Artificial grass green walls
Artificial grass is an ideal product for green walls. One of the disadvantages of natural grasses and plants is their strong dependence on water and light, which can be problematic against a wall. However, artificial grass remains green in any environment, regardless of temperature and sunlight exposure. It requires little to no maintenance, especially when used as a green wall.
Green walls and health
As mentioned, green walls are an ideal way to provide much-needed greenery in urban environments, which is urgently necessary. Over the past decades, we, as Dutch citizens, have massively migrated to cities, with over eighty percent of the population now residing in urban areas. Unfortunately, there’s limited space for greenery in most cities, which can lead to physical and mental health issues. Various studies have shown the correlation between health and the amount of greenery in the surroundings. Therefore, green walls can make a positive contribution in this regard.
Green walls inside or outside
Artificial grass green walls are suitable for both indoor and outdoor use. A green wall can be installed on exterior walls on the street but also in office buildings, hotel lobbies, or shopping centers, for instance. Another advantage of an artificial grass green wall is its sound-absorbing properties.
Costs of green walls
An artificial grass green wall is a low-maintenance solution, resulting in minimal ongoing costs once installed. This makes it ideal, for instance, for public spaces.
Kuta za kijani: bustani za wima kwa miji ya kijani Miji yetu inakuwa yenye idadi kubwa ya watu, ikiacha nafasi kidogo ya kijani. Watu wengi hawana bustani, na pia kuna upungufu wa maeneo ya kijani katika maeneo ya umma. Upungufu huo waweza kuwa na athari mbaya kwa hali njema ya wakazi wa majiji hayo. Kwa furaha, katika miaka ya karibuni, jitihada zaidi zimefanywa ili kuingiza tena mimea katika mandhari ya mijini. Balconies na terraces juu ya paa zinatumiwa sana. Hata hivyo, pia kuna suluhisho mbalimbali za ubunifu ambazo watu wengi hawafikiri mara moja. Kuta za kijani-kibichi ni mfano bora. Nyanda na bustani maridadi zenye wima hutoa majani yanayohitajiwa katika mandhari ya barabara bila kuchukua nafasi nyingi. Kuta za kijani ni nini? Watu wengi huhusianisha bustani na nyasi na mimea kwenye ardhi nje, lakini inawezekana kabisa kuwa na bustani dhidi ya ukuta. Kuta za kijani ni kuta ambapo bustani wima imewekwa. Ni tofauti na ukuta uliofunikwa na mimea ya kupanda. Kuta za kijani-kibichi zina kiini kinachounga mkono ukuzi na kuruhusu mimea ikue. Hilo pia huwezesha bustani zenye umbo la wima zilizobuniwa kwa uzuri. Nyasi bandia kuta za kijani nyasi bandia ni bidhaa bora kwa ajili ya kuta kijani. Moja ya hasara ya nyasi za asili ni utegemezi wao mkubwa kwa maji na mwanga, ambayo inaweza kuwa na shida dhidi ya ukuta. Hata hivyo, nyasi bandia hubaki kuwa ya kijani kibichi katika mazingira yoyote, bila kujali halijoto na mwangaza wa jua. Inahitaji matengenezo machache au hakuna matengenezo, hasa inapotumiwa kama ukuta wa kijani kibichi. Kuta za kijani kibichi ni njia bora ya kutoa kijani kibichi kinachohitajika sana katika mazingira ya mijini. Katika miaka ya hivi karibuni, idadi kubwa ya watu wa Uholanzi wamehamia mijini, na zaidi ya asilimia 80 ya wakazi wanaishi katika maeneo ya mijini. Kwa bahati mbaya, kuna nafasi ndogo ya kijani katika miji mingi, ambayo inaweza kusababisha masuala ya afya ya kimwili na kiakili. Uchunguzi mbalimbali umeonyesha uhusiano kati ya afya na kiasi cha mimea katika mazingira. Kwa hiyo, kuta za kijani-kibichi zaweza kuchangia vizuri katika jambo hilo.

Faida nyingine ya ukuta wa nyasi bandia ni uwezo wake wa kunyonya sauti. Kuta ya kijani ya nyasi ya bandia ni suluhisho la matengenezo ya chini, na kusababisha gharama ndogo za kuendelea mara moja imewekwa. Hii inafanya kuwa bora, kwa mfano, kwa ajili ya nafasi za umma.
