De oorzaken zijn divers en te vinden in broedgebieden, langs trekroutes en in - veelal Afrikaanse - overwinteringsgebieden. In de Sahel vormen met name veranderingen in het landschap een serieuze bedreiging voor veel trekvogelpopulaties. Deze veranderingen zijn zowel een gevolg van, als ook een risico voor de mensen die in deze regio in grote mate afhankelijk zijn van het landschap voor hun levensonderhoud. De door trekvogels en mensen gedeelde afhankelijkheid creëert echter ook mogelijkheden voor oplossingen; duurzaam landgebruik leidt tot behoud van natuurlijke hulpbronnen én tot herstel van biodiversiteit. Naast ecologisch inzicht is daarom ook sociaalgeografische kennis onontbeerlijk voor beschermingswerk. In dit artikel brengen we deze onderzoeksvelden dichter bij elkaar.Summary: Many European migratory bird populations show a (strong) negative trend. The causes are diverse and can be found scattered throughout their breeding grounds, along their migratory routes and in their - mostly African - wintering areas. In the latter category, landscape changes in the Sahel are a serious threat to many migratory bird populations. These landscape changes are both a consequence of, and a risk to, the people that depend to a large extent on the landscape for their livelihood in this region. This dependence shared by migratory birds and people also creates opportunities for solutions; sustainable land use leads to the conservation of natural resources and to the restoration of biodiversity. This appears to be an important strategy for the protection of migratory landbirds, as these species are widespread in the largely cultivated Sahel landscape. So, in addition to ecological insight, socio-geographical knowledge is also essential for this type of conservation work. In this article we strive to bring these fields of expertise closer together.Knowing what our migratory birds do when they are not in the Netherlands’ is usually the strongest drive for researching migratory routes and wintering areas of migratory birds among European researchers. In recent years an enormous amount of knowledge and insight has been generated in that area; insights that are necessary for shaping and prioritizing protection: where and when do which limiting factors occur? But just as important is the insight into the wider context of those limiting factors, for which socioeconomic knowledge is essential. After all, conservation starts with understanding. Show less

Show moreThe Blue Bird-of-paradise Paradisaea rudolphi (BBOP) is a globally threatened species restricted to the montane rainforest of Papua New Guinea (PNG). Local inhabitants hunt the BBOP for its feathers, which is one of the main reasons for its population decline. The feathers are used for both traditional and commercial purposes. So far virtually nothing is known about which factors enhance or decrease hunting pressure, and how this is influenced by ongoing market integration of local communities. Field research in PNG suggests that the demand for BBOP feathers and, with that, the collection intensity, primarily stem from traditional uses, such as head decoration. Interest in the traditional use of the feathers is particularly high in remote villages, while the value attributed to living birds is higher in less remote villages, suggesting a decrease of BBOP collection intensity with increased market integration. However, increased access to 'outside influences' (namely tourism and Christianity) may both decrease as well as increase hunting pressures. Finally, we argue that awareness-raising among local people, government officials and tourists may well be the most sensible conservation measure. Show less
