Lay Summary (German)

Lead
Im 20. Jahrhundert wurden in vielen Regionen der Erde gebietsfremde Bäume und Sträucher angepflanzt, weil man sich von ihnen verschiedene Nutzen erhoffte (z.B. Brennholz, Erosionsschutz, Schatten). Heute gehören einige von ihnen weltweit zu den invasivsten Pflanzen und verursachen gravierende ökologische und sozio-ökonomische Probleme. Das Projekt untersucht die Auswirkungen invasiver Gehölzpflanzen in drei Regionen Ostafrikas und erarbeitet Lösungsansätze zur Bekämpfung negativer Auswirkungen.
Lay summary

Inhalt und Ziele des Forschungsprojekts

Ein zentraler Aspekt des Projektes besteht darin, den Einfluss invasiver Gehölzpflanzen  auf die Lebensgrundlagen und -bedingungen der Bevölkerung in den betroffenen Gebieten zu bestimmen. Dazu werden Feldstudien durchgeführt, um lokale Auswirkungen invasiver Bäume und Sträucher sowie die Wahrnehmung und Handlungsbereitschaft betroffener Akteure zu untersuchen. Parallel werden räumliche Verbreitungsmodelle erarbeitet, um das Ausmass und die potentiellen Kosten der Invasionsprozesse auf regionaler und nationaler Ebene zu erfassen. In einer zweiten Phase des Projektes werden Lösungsansätze erarbeitet und deren nachhaltige Umsetzung getestet.

 

Wissenschaftlicher und gesellschaftlicher Kontext des Forschungsprojekts

Das Projekt soll bei der Produktion von Systemwissen (Ausmass und Auswirkungen der Invasionsprozesse) und von Transformationswissen (Integration von Invasionsbekämpfung in lokale Ansätze zur nachhaltigen Ressourcennutzung) einen Beitrag leisten. Die Erkenntnisse werden dazu dienen, negative Auswirkungen invasiver Gehölzpflanzen auf Biodiversität und Ökosystem-Dienstleistungen zu vermindern und damit die Lebensbedingungen der ärmeren Menschen im ländlichen Raum Ostafrikas zu verbessern.

Abstract

Invasive alien species (IAS) are key drivers of human-caused global environmental change as they threaten biodiversity and ecosystem services (ES). Woody plant species were repeatedly introduced in areas outside their native range, because they can provide goods and services to the rural poor. Several of these woody species have escaped cultivation and invaded agricultural and natural ecosystems, where their negative impacts on ES and human well-being progressively exceed the benefits local actors can derive from them. The overarching goal of our project is to help mitigate the negative impacts of woody IAS on ecosystem services and human well-being in East Africa. To achieve this goal, our multi-disciplinary consortium will generate and avail knowledge on invasion processes and on context-dependent environmental and socio-economic impacts of woody IAS, elaborate innovative control measures and develop and document Sustainable Land Management strategies that mitigate the negative impacts of woody IAS in East Africa.
