Promoting the conservation of biodiversity and associated services while increasing ecological food production is a major challenge for a sustainable future. Ecological intensification of tropical agroforestry and their multifunctionality presents an important contribution to this goal. However, few studies have so far addressed the highly complex interactions between local factors (i.e. genetic diversity of cacao varieties), site conditions (i.e. soil fertility) and landscape structure (i.e. surrounding habitat types; landscape connectivity) on pest suppression, pollination services, crop yields and possible tradeoffs or synergies in a comprehensive approach. In Peru and the Amazon, the ecological and commercial role of genetic diversity of cacao, including wild native relatives, is a most important, yet little studied feature. Addressing key knowledge gaps, we designed an experimental study to quantify the relative role of local cacao genetic diversity and landscape context on multiple ecosystem services (of birds, bats, ants and further arthropods contributing to biological pest control and pollination) as well as crop yield. We implement biocontrol and pollination exclosure experiments on 24 field sites and quantify all stages of the cacao life-cycle to develop suggestions for ecological intensification in the context of traditional farming practices. In collaboration with our Peruvian partners, we will disseminate results via publications and informative workshops to stakeholders such as farmers, national and international social-ecological NGOs.

促进保护生物多样性和相关服务，同时增加生态粮食生产，是可持续未来的一项重大挑战。热带农林业的生态强化及其多功能性为实现这一目标作出了重要贡献。然而，迄今为止，很少有研究涉及当地因素（即可可品种的遗传多样性）、立地条件（即土壤肥力）和景观结构（即周围生境类型;景观连通性）之间高度复杂的相互作用，涉及虫害抑制、授粉服务、作物产量以及综合办法中可能的权衡或协同作用。在秘鲁和亚马逊地区，可可遗传多样性的生态和商业作用，包括野生本地亲属，是一个最重要的，但很少研究的特点。为了解决关键的知识差距，我们设计了一项实验研究，以量化当地可可遗传多样性和景观环境对多种生态系统服务（鸟类，蝙蝠，蚂蚁和其他节肢动物对生物害虫控制和授粉的贡献）以及作物产量的相对作用。我们实施生物控制和授粉围封实验的24个现场和量化的可可生命周期的各个阶段，在传统的农业实践的背景下，生态集约化发展的建议。我们将与秘鲁合作伙伴合作，通过出版物和信息研讨会向农民、国家和国际社会生态非政府组织等利益攸关方传播成果。
