    Driven by our vision of a world where all people have viable livelihoods supported by healthy and productive landscapes, our global team of science, research, development, institutional and resource professionals seeks to better combine the science of discovery with the science of delivery. To realize this vision, we focus on four key interacting themes: By combining more productive trees with more resilient and profitable agricultural systems and a sounder understanding of the health of the soil, land and people that is part of ‘greener’, better governed landscapes, we offer valuable and timely knowledge products and services to the global community as it tackles the major challenges of the Anthropocene. These include dealing with climate change; low soil carbon; widespread forest, tree and soil loss leading to degradation; poverty; demographic upheavals and conflict; and securing equitable futures for all with a special focus on women and children.

Quantitative and up-to-date information on ecosystem characteristics and land health constraints are needed to understand land degradation trends and patterns, as well as formulating appropriate and specific interventions. A study was carried out in the Western Highlands of Cameroon using the Land Degradation Surveillance Framework (LDSF) to:1) establish baseline measurements to monitor and assess land management impact and ecosystem health over time, 2) describe land health patterns in land uses and associated degradation and 3) deduce implications and propose targets to engage with stakeholders to develop site-specific agroforestry and other sustainable land management interventions.The LDSF is a spatially stratified, random sampling design framework use to characterise sentinel sites consisting of 10 km×10 km blocks and clusters of 160 plots. This report provides preliminary analyses of the key factors that indicate the land and vegetation health of the Bamendjou sentinel site. These indicators provide a basis for assessing land degradation and productivity as well as the availability of key ecosystem services that are ecological functions and contribute to livelihoods improvement. The study identified and classified the indicators into ecological characteristics, soil physical and chemical indicators. We observed that the site is dominated by mountainous relief which is as inappropriate for intensive and continuous cropping without conservation practices. Over 88% of the site (8,800ha) was under cultivation at the time of the survey implying that nearly every hectare of the land including the steepest slopes is cultivated. Majority of land of the site (> 55%) has slope greater than 10% however, the soil erosion risk across the site was minimal. Trees and shrubs densities across the site were on average 143 tree ha-1and 192 shrub ha-1respectively. Though not significant, both shrub and tree densities were higher in cultivated as compared to uncultivated.The herbaceous cover rate across the entire site was found to be annual and was estimated to be between 15-40% for cultivated and between 40 –65% for uncultivated lands.Textural analysis of the samples indicated that the soils have a high content of Clay (75.64%) . Infiltration was observed to be higher in cultivated than uncultivated lands. The estimated cluster-level frequencies of root depth restriction were 0.62% and 3.62% within the 0-20cm and 0-50cm depth respectively.We observed a wide range of values for SOC across the study site with significant differences in SOC concentration among land uses.The high proportions of lands of the study site are slightly acidic with pH ranging from 5.1-6.1 without any significant difference among land use.
