Trees for Food Security Project participatory trials follow up study in Ethiopia
No full textA survey was conducted in 2014 to determine farmers’ perception on the agroforestry trials established under the Australian Centre for International Agricultural Research (ACIAR) funded ‘Trees for Food Security’ (T4FS) project in Ethiopia. The trials form part of Work Package (WP) 2 activities- obtaining and documenting feedback from farmers with participatory trials. The specific objectives of the study were to: 1) Determine the number of farmers and technologies in place. 2) Understand farmers’ perception towards effectiveness of the technologies. 3) Determine challenges faced in implementation of the technologies and 4) Identify opportunities for improvement of the technologies
SEUSA: Biodiversity, vegetation structure, soil quality, farming practice in cacao plantations and other land uses in Irazola, Ucayali, Peru
No full textLa base de datos cuenta con la información 41 productores cacaoteros. Los cacaoteros prioritarios se caracterizan por contar además de sus parcelas de cacao con otros usos de suelo dentro de sus fincas. Se estudiaron un total de 158 unidades de muestreos, distribuidas en 41 cacaotales (CA), 28 purmas bajas (PB), 29 purmas medias (PM), 30 purmas altas (PA) y 30 monte real (MR); los cuales se muestran con mayor detalle en la Tabla 3. (see separate descriptive file)
Replication Data for: Effects of Rootstock Type and Scion Cultivar on Grafting Success and Growth of Mango (Mangifera indica L.) Seedlings
No full textAim: To evaluate the effects of three types of rootstocks: (i) Ngwangwa (ii) Sindano and (iii) Zinzi
commonly used in the coastal belt of Tanzania on grafting success and seedling growth of six
improved mango cultivars: (i) Apple (ii) Ngowe (iii) Kent (iv) Keitt (v) Alphonso and (vi) Tommy
Atkins.
Study Design: Plants were arranged in a split plot design with three replications. The rootstocks
were main plots while the scion cultivars were subplots.
Place and Duration of Study: At Chambezi research farm of Mikocheni Agricultural research
institute (MARI) located at 6°30’S and 38°55’E at al titude of 12 meters above sea level in the
coastal belt of Tanzania, from January 2014 to March 2015
Estudiando el Mercado de carbon Forestal en Perú
No full textSurvey data of private sector knowledge and understanding of climate change and carbon markets, of its footprint calculations and managing actions as well as of its offsetting actions with a focus on the barriers and the limiting factors
Tree height and basal diameter
No full textTree height and basal diameter measurements were taken for the period between Dec 2012 and March 2016 to show growth trend
Simple Crop Corg Model
No full textThe model was set up to generate “soil carbon transition curves” that are consistent with simple assumptions about soil carbon dynamics during fallow and cropping stages. The model provides estimates of yield, organic matter dynamics, yield per unit labor and net GHG emissions per unit yield

Review of extension systems in Ethiopia- East shewa, West Shewa and East Wollega zones
No full textAs part of the baseline survey for the ACIAR- funded Trees for Food Security Project, a literature review and key informants’ interviews were undertaken in Ethiopia to understand the status of the extension system. The major areas of focus were: Extension technologies disseminated to farmers; Community engagement; Capacity and efficiency; Linkage with other institutions; Commercialization and marketing and local innovation. Findings from the studies contributed to improved understanding of what extension approaches work best in different contexts encapsulated in tools for customizing scaling up methods to local farming conditions
Replication data for: Soil chemical properties in 4 different landuse in the Cameroon rainforest.
No full textThis study was carried to determine soil chemical properties in 4 different landuse in the Cameroon rainforest zone. 192 plots were sampled and the quantity of different elements were recorded from different land use
Replication Data for: Using leaf area index (LAI) to assess vegetation response to drought in Yunnan province of China
No full textClimatic extremes such as drought have becoming a severe climate-related problem in many regions all over the world that can induce anomalies in vegetation condition. Growth and CO2 uptake by plants are constrained to a large extent by drought. Therefore, it is important to understand the spatial and temporal responses of vegetation to drought across the various land cover types and different regions. Leaf area index (LAI) derived from Global Land Surface Satellite (GLASS) data was used to evaluate the response of vegetation to drought occurrence across Yunnan Province, China (2001-2010). The meteorological drought was assessed based on Standardized Precipitation Index (SPI) values. Pearson's correlation coefficients between LAI and SPI were examined across several timescales within six sub-regions of the Yunnan. Further, the drought-prone area was identified based on LAI anomaly values. Lag and cumulative effects of lack of precipitation on vegetation were evident, with significant correlations found using 3-, 6-, 9- and 12-month timescale. We found 9-month timescale has higher correlations compared to another timescale. Approximately 29.4% of Yunnan’s area was classified as drought-prone area, based on the LAI anomaly values. Most of this drought-prone area was distributed in the mountainous region of Yunnan. From the research, it is evident that GLASS LAI can be effectively used as an indicator for assessing drought conditions and it provide valuable information for drought risk defense and preparedness
