Delineation of Cocoa Agroforests Using Multi-Season Sentinel-1 SAR Images versus RapidEye multi-spectral image
No full textThe data is based on field inventory from 2015 to 2017 to map cocoa agroforests and other vegetation and non-vegetation land cover. The dataset consists of geospatial data (shapefiles) of the land cover and land use in the study landscape in Bokito - within the forest-savannah transition zone of Centre Cameroon.
The main aim of the study was to discriminate cocoa agroforest from transition forest; we compare the performance of texture-based classification of SAR (Synthetic Aperture Radar) images of Sentinel-1 with the result of "business as usual" multi-spectral optical image classification using a RapidEye image mosaic for the study landscape
West Africa Household Baseline
No full textThis study consists of sex-disaggregated data and other related materials generated as part of the Sentinel Landscapes Network household survey baseline in West Africa sentinel site in Burkina Faso. A total of 600 households were surveyed between October and November 2013 from 31 villages namely: Sakou, Nongsom, Temnaoré, Bogoname, Loaga, Badinogo2, Rambo Watinooma, Bam, Sam, kouka, Dao, Gao, Kassolo, Cassou, Bongnounou, Pro, Tiabona, Vrassan, Kou, Mao-Nassira, Tékourou, Bechembelle(Bichenboi), Bugubelle, Funsi, Gbele, Hellebe(Halemboi), Jijen, Kojokpere, Kuroboi, Sakai, Welembelle. The data consists of information on household demographics, migration, education, asset ownership, income sources, household food security, progress out of poverty, crop production and sales, livestock products, participation in credit markets, social networks, and natural resource use. In compliance with the CGIAR protocol on collecting sex-disaggregated data, approximately 50% of the respondents interviewed were women.

Replication data for: Gender roles and knowledge in plant species selection and domestication: case study in South and Southeast Sulawesi
No full textWomen and men have different sets of knowledge, experiences, and strategies in addressing aspects of plant domestication such as plant propagation, management, utilisation and marketing. Identification of gender roles and knowledge related to tree domestication is important in planning for tree-basedlivelihood enhancement and sustainable environmental management, however, such identification has not yet beensufficiently researched to date. This study investigated gendered selection of economically priority species and their domestication in South and Southeast Sulawesi. From the focus group discussion, both men and women give priority to tree species with high economic value; the management of those species is a stronger priority for men but is also expressed by women. However, specifically for their livelihoods, women are keen to domesticate vegetables and other annual crops that contribute directly to household food security and nutrition

Replication Data for: Rubber tree allometry, biomass partitioning and carbon stocks in mountainous landscapes of sub-tropical China
No full textExpansion of rubber plantations into sub-optimal environments has been a dominating land conversion in continental South-East Asia in the last decade. Regional evaluation of the carbon sequestration potential of rubber trees depends largely on the selection of suitable allometric equations and the biomass-to-carbon conversion factor. Most equations are age-, elevation-, or clone-specific, and their application therefore gives uncertain results at the landscape level with varying age groups, elevation ranges, and clone types. Currently, for rubber-based systems, none of the allometric equations takes environmental factors (e.g. climate, topographic condition, soil properties, and management scheme) into consideration to allow pan-tropical usage. Against this background, 30 rubber trees with a root profile of up to 2 m were destructively harvested and 882 rubber trees were measured non-destructively in 27 plots, covering rotation lengths of 4–35 years, elevation gradients of
621–1127 m, and locally used clone types (GT1, PRIM600, Yunyan77-4) in mountainous South Western China. Allometric equations for aboveground biomass (AGB) estimations considering diameter at breast height (DBH), tree height (H), and wood density were evaluated. We also tested goodness of fit for the recently proposed pan-tropical forest model, which includes a bioclimatic factor E, combining indices of temperature and precipitation variability and drought intensity
Evaluating the restoration of the commons: LDSF field data
No full textThe dataset is based on ecological field data collection carried out in prioritized common land areas in 288 treated and matched control villages in the states of Andhra Pradesh, Karnataka, Odisha, and Rajasthan. It is based on the Land Degradation Survelliance Framework (LDSF) methodology. The LDSF methodology typically follows a standardized sampling design, where clusters are selected within 10-by-10-kilometer sentinel sites and then 10 0.1 hectare plots are randomly selected within each cluster. Each plot is then divided into four 0.01-hectare sub-plots from which field measurements are subsequently taken. We adapted this sampling approach to meet the unique needs of our study. Specifically, we treated each prioritized common land area as a sampling cluster. We then randomly sampled 10 plots (including their associated four sub-plots) within each. We then took inventories of all the trees, shrubs, and saplings in each of the 40 sampled sub-plots. We further randomly selected two of the plots for water infiltration measurement, which took place in the central sub-plot of the sampled plots in question. Given the time and effort involved, it was not possible to take these measurements in all 10 plots

Land and Soil Health Assessment in the Nile-Congo Sentinel Landscape
No full textThe LDSF was carried out at two-100 km2 sites within the Nile-Congo Sentinel Landscape: Kericho in Kenya.
The LDSF is a spatially stratified, randomized sampling design, developed to provide a biophysical baseline at landscape level and a monitoring and evaluation framework for assessing processes of land degradation and effectiveness of rehabilitation measures over time.
Measured variables include: land cover, tree and shrub densities, tree biodiversity, erosion prevalence, infiltration capacity, along with an assessment of impact to habitat and occurrence of soil conservation structures. Soil samples were also collected (320 top (0-20 cm) and sub (20-50 cm) soil samples per site) and were processed in Burkina Faso. Processed samples were subjected to infrared spectroscopy and wet chemistry analysis. These combined data sets will be used to assess soil and ecosystem health for the landscape in more detail
Replication Data for How to be an ant on figs
No full textMutualistic interactions are open to exploitation by one or other of the partners and a diversity of other organisms, and hence are best understood as being embedded in a complex network of biotic interactions. Figs participate in an obligate mutualism in that figs are dependent on agaonid fig wasps for pollination and the wasps are dependent on fig ovules for brood sites. Ants are common insect predators and abundant in tropical forests. Ants have been recorded on approximately 11% of fig species, including all six subgenera, and often affect the fig–fig pollinator interaction through their predation of either pollinating and parasitic wasps. On monoecious figs, ants are often associated with hemipterans, whereas in dioecious figs ants predominantly prey on fig wasps. A few fig species are true myrmecophytes, with domatia or food rewards for ants, and in at least one species this is linked to predation of parasitic fig wasps. Ants also play a role in dispersal of fig seeds and may be particularly important for hemi-epiphytic species, which require high quality establishment microsites in the canopy. The intersection between the fig–fig pollinator and ant–plant systems promises to provide fertile ground for understanding mutualistic interactions within the context of complex interaction networks
