The few remaining Afromontane forest fragments in northern Ethiopia and the surrounding degraded, semiarid matrix form a habitat mosaic of varying suitability for forest birds. To evaluate the effect of recent land rehabilitation efforts on bird community composition and diversity, we studied bird species distributions in ten small forest fragments (0.40-20.95 ha), five grazing exclosures (10-year-old forest restoration areas without wood extraction and grazing livestock) and three grazed matrix sites during the rainy season (July-October 2004) using 277 one-hour species counts. Based on the distribution pattern of 146 bird species, sites were assigned to one of three bird communities (birds of moist forest, dry forest or degraded savanna), each occupying a well-defined position along an environmental gradient reflecting decreasing vegetation structure and density. All three communities were representative of the avifauna of Afrotropical Highland open forest and woodland with a high proportion of invasive and competitive generalist species (31%). Apart from these, exclosures shared more species with forest fragments (20%) than did the grazed matrix (5%), indicating local ecosystem recovery. By increasing habitat heterogeneity, exclosures have the potential to enhance landscape connectivity for forest birds and are, therefore, an effective instrument for conserving species in a fragmented landscape. However, 52 bird species (36%) occurred exclusively within forest patches and many forest birds that use exclosures are unlikely to maintain viable populations when forest fragments disappear, particularly as forest fragments may be a critical resource during the hot dry season. This highlights the high conservation value of small isolated forest fragments for less tolerant, forest-limited and/or biome-restricted species

The coastal town Ada in Ghana is threaded by a severe coastal erosion. A protection scheme has to be designed to protect the town. Since the area is ecologically important, e.a. due to the presence of turtles, both during the design process and during the construction phase actions to diminish possible negative effects have to be considered. The design is supported by measuring campaigns and numerical modeling of the currents, waves and morphology.

Land is a scarce resource and should be used in such a way that the increasing global demand for food and feed can be fulfilled, while ensuring sufficient levels of ecosystem services. While the demand on open space to deliver a multitude of services is increasing, drivers like global change and urbanization are undermining these services. Decision makers, from individual farmers to spatial planners, are in need of appropriate diagnostic tools to estimate trade-offs and synergies associated with land allocation and land use intensity decisions. This often implies trade-offs between food and biomass production and other non-provisioning ecosystem services. This paper presents an assessment on the farm scale using an integrated approach that combines spatial and economic analyses. It relies on the ecosystem services concept to evaluate land use alternatives. The analysis highlights current challenges to reach a societal optimal land allocation. INTRODUCTIONPopulation pressure results in an increasing demand for food and bio-energy products and hence also in an increasing demand for agricultural land (Meyfroidt et al., 2013;Tscharntke et al., 2012). This demand is in competition with the additional demand for land for residential, conservation, forestry, recreational, and other purposes (Zasada, 2011). With land as an increasingly scarce resource, spatial planners seek to balance land use allocation among competing stakeholders. This has led to a polarization in land use policies between demands for expanding urbanized fabric and the remaining open space used for agriculture, whilst natural areas are largely pushed back to relatively small and fragmented relics. Spatial planning has mainly focused on allocation of land to space demanding sectors and minimizing spatial conflicts. This approach falls short in considering present-day demands for multifunctionality, sustainability, ecosystem services, resilience and adaptive governance. While an integrative and spatially explicit approach to land allocation is highly needed, it is largely missing (Bomans et al., 2010b;Termorshuizen and Opdam, 2009). Particularly in strongly urbanized regions, the relation between the availability and use of space, and the potential services this space is able to provide to society, needs to be explored further. Increasing service delivery per unit of space can allow a decreasing spatial requirement for delivering this service, and hence, freeing space for other services. Fragmented peri-urban landscapes in particular, where interfaces between different forms of land use and associated actors are plenty, are in need of innovative concepts for land use allocation. Meanwhile, concepts of multifunctionality and ecosystem services already bridge the distinction between classical sectors like agriculture, nature and forestry. In the light of food and biomass production, the principal challenge is to simultaneously assess and maximize production as well as the other ES provided by bioproductive land (Balmford et al., 2012) which inevi...
