| description | In this day and age we are faced with urban cores getting hotter, with the main drivers
being climate change and the urban heat island effect. This gets even more complicated
as the parts of Europe that have the largest need too cool down, i.e. the south, has the
least amount of space available for interventions in the form of green space. The aim for
this study is to connect the potential between ideas from ancient desert cultures and the
current climactic challenges in the urban framework.
This thesis consists of two parts, the first is to identify gardening techniques from the
following desert cultures: Ancient Egypt, Ancient Persia and Ancient Andalusia. The
second part is to examine what microclimactic effect these techniques would have on an
open urban area in Granada, Spain. The effects are examined using a software that
examines the climactic effects of changing the radiation and latent heat flux.
Fifteen main techniques were found to be relevant to combat the challenges of hot
microclimates in the city. Some of these techniques are chosen to be part of a scenario of
intervention. On a normal summers day with an air temperature of 34.8 oC, the difference
of intervention and no intervention is 5.01 oC in mean radiant temperature (max). The
areas with the maximal thermal change had their mean radiant temperature lowered by
7.31 oC. It can therefore be concluded that the garden techniques from these desert
cultures can be used in city spaces to have a real impact on the microclimate. This is a
possible solution for the climate adaptation of the cities in the south of Europe that have
little space for very large interventions. |

En esta época nos enfrentamos a núcleos urbanos cada vez más calientes, como principales impulsores; el cambio climático y el efecto isla de calor urbano. Esto se vuelve aún más complicado ya que en el sur de Europa dónde hay la mayor necesidad de combatir el calor, no disponemos de espacios de intervención. El objetivo de este estudio es conectar el potencial entre las ideas de las antiguas culturas del desierto y los desafíos climáticos actuales en el marco urbano. Esta tesis consta de dos partes, la primera consiste en identificar técnicas de jardinería de las siguientes culturas del desierto: Antiguo Egipto, Antigua Persia y Antigua Andalucía. La segunda parte es examinar qué efecto microclimático tendrían estas técnicas en un área urbana y expuesta en Granada, España. Los efectos se examinan utilizando un programa que calcula los efectos climáticos de cambios en la radiación y flujo de calor latente. Quince técnicas principales son relevantes para combatir los desafíos de los microclimas cálidos en la ciudad. Algunas de estas técnicas se eligen para formar parte de un escenario de intervención. En un día normal de verano con una temperatura ambiental de 34,8 oC, la diferencia entre la intervención y no intervención es de 5.01 oC en mean radiant temperature (máx.). Las partes con el cambio térmico más grande tuvieron su mean radiant temperature bajada en 7,31 oC. Por lo tanto, se puede concluir que las técnicas de jardinería de estas culturas del desierto se pueden utilizar en los espacios de la ciudad para tener un impacto real en el microclima. Esta es una posible solución para la adaptación climática de las ciudades del sur de Europa que disponen poco espacio para intervenciones muy grandes. Vi ställs nu inför stadskärnor som blir allt varmare, pådrivet av klimatförändringar och den urbana värmeöeffekten. Detta blir ännu mer komplicerat då de delar av Europa som har störst behov av svalka, det vill säga Sydeuropa, har minst grönytor tillgängliga för interventioner. Syftet med denna studie är att koppla samman potentialen mellan idéer från antika ökenkulturer och de nuvarande klimatutmaningarna i en urban kontext. Examensarbetet består av två delar, den första är att identifiera trädgårdstekniker från följande ökenkulturer: Det antika Egypten, det antika Persien och det antika Andalusien. Den andra delen är att undersöka graden av mikroklimatisk effekt teknikerna har på ett öppet stadsområde i Granada, Spanien. Effekterna undersöks med hjälp av en programvara som räknar ut klimatiska effekter av förändringar i strålning och latent värmeflöde (latent heat flux). Femton huvudtekniker visade sig vara relevanta för att möta mikroklimats-utmaningarna i staden. Vissa av dessa tekniker är valda för att ingå i ett interventionsscenario. Under en normal sommardag med en lufttemperatur på 34,8 oC är skillnaden mellan ingrepp och inget ingrepp 5.01 oC i mean radiant temperature (max). Delarna med den maximala termiska förändringen fick sin mean radiant temperature sänkt med 7,31 oC. Vi kan därför dra slutsatsen att trädgårdsteknikerna från dessa ökenkulturer kan användas i stadsrum för att ha en verklig inverkan på mikroklimatet. Detta är en möjlig lösning för klimatanpassningen av städerna i södra Europa, som saknar utrymme för mycket stora ingrepp. SLU/Dept. of Landscape Architecture, Planning and Management (from 130101) 2022 H2 eng swe spa https://stud.epsilon.slu.se/17698/ |
