This chapter first discusses the potential of trees to modify the soil and its impact on soil biota. The exploration of the linkages between the biological activity of soil organisms in agroforestry systems and their impact on soil-based ecosystem services and soil health follows next. Then recent advances in soil...

In this chapter, we first examine key concepts that are relevant to understanding the links between biodiversity and ecosystem services. We then review the relationship between biodi-versity and ecosystem services, as well as the complexities arising from such linkages. We then provide an in-depth description of the links between biodiversity...

Abstract. The recent interest in multi-functional agricultural landscapes has not been matched with formal assessment of the roles that trees play across the spectrum of ecosystem services (ESs) provided in Sub-Saharan Africa (SSA). A structured literature review (1995–2014) assessed 350 journal articles about provision of one or more ESs by...

Abstract. The production of sufficient food for an increasing global population while conserving natural capital is a major challenge to humanity. Tree-mediated ecosystem services are recognized as key features of more sustainable agroecosystems but the strategic management of tree attributes for ecosystem service provision is poorly understood. Six agroforestry and tree...

The soil environment is likely the most complex biological community. Soil organisms are extremely diverse and contribute to a wide range of ecosystem services that are essential to the sustainable function of natural and managed ecosystems. The soil organism community can have direct and indirect impacts on land productivity. Direct...
