Importance of considering technology growth in impact assessments of climate change on agriculture
International Maize and Wheat Improvement Center (CIMMYT)
Abstract
Many assessments of climate change impacts on global crop yields project declines as early as the 2020s. Losses are projected to increase with time, up to 50% by the 2080s. We carry out a systematic global review and compare published projections of climate change impacts from 34 studies and �?�4500 data points for the 2020s for maize, rice and wheat at country level…

Inheritance of Striga hermonthica adaptive traits in an early?maturing white maize inbred line containing resistance genes from Zea diploperennis
International Institute of Tropical Agriculture (IITA)
Abstract
Striga hermonthica can cause as high as 100% yield loss in maize depending on soil fertility level, type of genotype, severity of infestation and climatic conditions. Understanding the mode of inheritance of Striga resistance in maize is crucial for introgression of resistance genes into tropical germplasm and deployment of…

Linking soil respiration and water table depth in tropical peatlands with remotely sensed changes in water storage from the gravity recovery and�climate experiment
Center for International Forestry Research (CIFOR)
Abstract
Carbon dioxide (CO2) emissions from Southeast Asia peatlands are contributing substantially to global anthropogenic emissions to the atmosphere. Peatland emissions associated with land-use change, and fires are closely related to changes in the water table level. Remote sensing is a powerful tool that is…

Genetic diversity and selection of genotypes to enhance Zn and Fe content in common bean
Department for International Development (DFID)
Abstract
Common bean (Phaseolus vulgaris L.) is an important source of dietary protein and minerals worldwide. Genes conditioning variability for mineral contents are not clearly understood. Our ultimate goal is to identify genes conditioning genetic variation for Zn and Fe content. To establish mapping populations for this objective, we tested mineral content of 29 common bean genotypes. Chemical…

Rising temperatures reduce global wheat�production
Abstract
Crop models are essential tools for assessing the threat of climate change to local and global food production1. Present models used to predict wheat grain yield are highly uncertain when simulating how crops respond to temperature2. Here we systematically tested 30 different wheat crop models of the Agricultural Model Intercomparison and Improvement Project against field experiments in which growing season mean temperatures ranged from 15 C to 32 C, including experiments with artificial…

Integrating diversity of smallholder coffee cropping systems in environmental analysis
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/105567
Abstract
Purpose
Coffee represents an important trade asset internationally. Around 70% of global coffee production is provided by 25 million smallholders farmers. In recent decades, coffee systems have been transformed into more intensified systems of coffee monoculture. The general objectives of this paper are to provide a better picture…

Nicaragua’s agroecological transition: Transformation or reconfiguration of the agri-food regime?
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/104043
Abstract
Agroecology started to amplify agroecology in Nicaragua in the 1980s and was translated into national policy in 2011. Using the Multi-Level Perspective on sustainability transitions (MLP), this paper explores whether the rise of agroecology has fundamentally transformed Nicaragua’s agri-food system. Drawing on the…

Abstract
Angular leaf spot (ALS), caused by Pseudocercospora griseola, is one of the most devastating diseases of common bean (Phaseolus vulgaris L.) in tropical and subtropical production areas. Breeding for ALS resistance is difficult due to the extensive virulence diversity of P. griseola and the recurrent appearance of new virulent races. Five major loci, Phg‐1 to Phg…

Abstract
Wrapper methods are a type of feature selection method that finds a subset of variables to improve the performance of a classifier by removing redundant and irrelevant variables. The use of a wrapper implies that each time a candidate solution is explored, the classifier is evaluated on the quality measures selected (e.g. accuracy or precision). Though…
