Germplasm Collection Gaps and Species Richness of Wild Relatives of Important Root, Tuber and Banana Crops.

Nora P Castañeda Álvarez, Colin K Khoury, Chrystian C Sosa, Harold A Achicanoy & Vivian Bernau
The wild relatives of crops represent a major source of valuable traits for crop improvement. These resources are threatened by habitat destruction, land use changes, and other factors, requiring their urgent collection and long-term availability for research and breeding from ex situ collections. We propose a method to identify gaps in ex situ collections (i.e. gap analysis) of crop wild relatives as a means to guide efficient and effective collecting activities.

Climate Regions of Cassava in Africa

International Center For Tropical Agriculture
Cassava climate regions is based on means growing season temperature, number of dry season months, daily temperature range and seasonality.

Analysis of threats to South American flora and its implications for conservation

Julian Ramirez Villegas, Andy Jarvis & Jerome Touval
Study: A set of seven threats to natural ecosystems derived from a previous study (Jarvis et al. 2010), combined with a dataset of occurrences from 16,339 species, and also with the World Database of Protected Areas were used to analyse the patterns of threats to flora in South America and its conservation. Data: Data tables with results of assessment of threat and conservation level for all South American plant species for which there was data...

CCAFS Gender Survey – Colombia Climate Smart Village

CIAT & IFPRI
The purpose of this survey is to gather gender-disaggregated data on agricultural activities, decision-making, weather information, risk-perception and values from rural households. In Phase 2, the gender survey was adapted and implemented in other sites. It was adapted to include some of the production information from IMPACT-Lite since that survey has not been implemented in the new sites. This intra-household survey collects information related to household characteristics, farm production, decision-making, CSA adoption, access to agro-climate...

A Baseline Study of Autonomous Adaptation Against Drought Among Thai Rice Farmers, CURE

Manzanilla, Dr. Digna, Chamarerk, Dr. Varapong & Leo Angelo Ocampo
This study in general aims to look at the impacts of drought on rice production, assess risk/vulnerability, and determine adaptation strategies of rice farming households for better targeting of planned adaptation strategies. The emphasis would be on the possibility of rice varietal introduction as a planned adaptive strategy. It is guided by the following research questions: 1. Is drought a hazard farmers face in the study areas? 2. What are the possible impacts of drought...

Baby Trial Monitoring Survey of Participatory Varietal Selection under STRASA

Paris, Dr. Thelma
To evaluate the performance of stress-tolerant varieties in farmer's field and compared it with the common varieties (local check).

Replication data for: Threats to cassava production: known and potential geographic distribution of four key biotic constraints

Beatriz Vanessa Herrera Campo, Glenn Hyman & Anthony Bellotti
The potential distribution map of the Cassava Greenmite is the result of a weighted overlay combination of several ecological models and a set of environmental variables. Models used were Environmental Distance, Genetic Alrgorithm for Rule-set Production and Support vector Machines . Environmental variables include: Bioclim dataset, number of consecutive dry months, aridity index, potential evapotranspiration and altitude. The potential distribution map of whitefly (Bemisa tabacci) provides a global potential distribution in order to know the...

Replication data for: The Cassava Mealybug (Phenacoccus manihoti) in Asia: First Records, Potential Distribution, and an Identification Key

Soroush Parsa, Takumasa Kondo & Amporn Winotai
Potential distribution of Cassava Mealybug (Phenacoccus maniholi). Pest risk map, based on model predicting climatic suitability for Phenococcus maniholi. Climatic suitability is estimated by the Eco climatic index (EI), values greater than 20 indicate high risk of infestations.

Failed Season drought probability

Peter G Jones & Philip K Thornton
This map estimates the drought probability based on the water balance and simulated daily rainfall. A failed season occurs when there is insufficient water to meet crop requirements. The failed season algorithm (FSA) has been used in a number of application including Hyman et al. 2008.

Assessing relevant climate data for agricultural applications

Julian Ramirez Villegas & Andrew J Challinor
Data: Data tables with results of assessment of skill of CMIP3 global climate models as well as interpolation skill of WorldClim Study: Here we performed a review of relevant aspects in relation to coupling agriculture climate predictions, and a three-step analysis of the importance of climate.

Bundling Health Insurance and Microfinance

Abhijit Banerjee, Esther Duflo & Richard Hornbeck
Microfinance institutions have started to bundle their basic loans with other financial services, such as health insurance. Using a randomized control trial in Karnataka, India, we evaluate the impact on loan renewal from mandating the purchase of actuarially-fair health insurance covering hospitalization and maternity expenses. Bundling loans with insurance led to a 16 percentage points (23 percent) increase in drop-out from microfinance, as many clients preferred to give up microfinance than pay higher interest rates...

Project Generasi: Conditional Community Block Grants in Indonesia

Benjamin Olken, Junko Onishi & Susan Wong
We report an experiment in 3,000 villages that tested whether incentives improve aid efficacy. Villages received block grants for maternal and child health and education that incorporated relative performance incentives. Subdistricts were randomized into incentives, an otherwise identical program without incentives, or control. Incentives initially improved preventative health indicators, particularly in underdeveloped areas, and spending efficiency increased. While school enrollments improved overall, incentives had no differential impact on education, and incentive health effects diminished over...

Replication Data for: Predicting the future climatic suitability for cocoa farming of the leading producer countries, Ghana and Ivory Coast.

Peter Läderach, Armando Martinez Valle, Götz Schroth & N Castro
Data for current and future suitability for cocoa farming of the world's leading producer countries, Ghana and Ivory Coast. Based on species distribution modelling: MaxEnt.

Farmer's Preferences for Abiotic Stress Tolerance in Hybrid versus Traditional Rice: Evidence from Bihar, India (2012-13)

International Food Policy Research Institute (IFPRI)
The survey,Farmer's Preferences for Abiotic Stress Tolerance in Hybrid versus Traditional Rice: Evidence from Bihar, India (2012-13), was designed to assess farmer's willingness to pay for drought-tolerant paddy in Bihar, India. The survey includes carefully designed discrete choice experiments and a risk experiment to collect information on demand for drought tolerance characteristics in rice and the role of both the public and the private sector in the research and development of the same. The data...

Assessing the effectivness of on-farm conservation projects in the High Andes

M. Bellon & E. Gotor
The objective was to assess the effectiveness of five on-farm conservation projects involving native crops maintained by smallholder farmers in the High Andes of South America. The data set includes variables from a household survey that took place in 3 countries: Ecuador, Peru, Bolivia. Househould survey with a stratified random sample of 748 households. The survey elicited information on project participation, application of the options provided by project interventions and examples of how they were...
