Monitoreo agroclimático participativo para rescatar la producción agrícola del Corredor Seco centroamericano
Centroamérica está enfrentando la peor sequía de los últimos 30 años. El fenómeno de El Niño se sumó a los efectos del cambio climático en el Corredor Seco, zona comprendida por Guatemala, Honduras, Nicaragua y El Salvador, donde más de 3.5 millones de personas están luchando por rescatar sus cosechas ante la falta de…

Ecosystem services, the value that has no price
Should we put a price on ecosystem services in order to protect them? How can we arrange it so that the services and ecosystems that are protected by the indigenous peoples receive appropriate recognition? How can the plans for territorial legislation be a complement to the instruments and knowledge of the indigenous communities? What is needed so that the focus of ecosystem services…

¿Por qué la industria ecuatoriana importa café si el país tiene la capacidad de producirlo?
Para combatir el déficit actual que tiene Ecuador en producción de café, el Gobierno está estimulando la compra interna de café robusta, generando un ambiente favorable para mejorar la relación entre la industria y los productores nacionales. En este momento, la industria ecuatoriana requiere alrededor de un millón de sacos de 60 kilos de…

Abstract
Surveys were made of rural artisan cheese factories located in the region of Olancho, Catacamas, and Juticalpa in Honduras (n=10) and in Esquipulas and Muy-Muy in Nicaragua (n=13). The objective was to analyze the milk market of small rural artisan cheese factories in livestock watersheds of Honduras and Nicaragua…

Forage legumes for improved fallows in agropastoral systems of subhumid West Africa. II. Green manure production and decomposition after incorporation into the soil
International Livestock Research Institute (ILRI)
https://hdl.handle.net/10568/27817
Abstract
A short-term improved fallow system based on forage legumes for enhancing crop and livestock components of mixed farming systems was tested in the subhumid zone of West Africa. As part of the evaluation, the ability of 11 legume species (Centrosema macrocarpum…

Off-types indicate natural outcrossing in five tropical forage legumes in Colombia
International Livestock Research Institute (ILRI)
https://hdl.handle.net/10568/27812
Abstract
Flower colour has been used as a simple morphological marker for genetic studies in many species, including legumes. In several tropical forage legumes, grown to evaluate their environmental adaptation or for seed increase, white-flowered plants were observed when the predominant flower colour was either yellow (Chamaecrista rotundifolia)…

The climate of cloud forests
Department for International Development (DFID)
Abstract
This paper analyses the climatic conditions prevailing at sites where tropical montane cloud forests (TMCF) have been reported. Spatial data-sets of climate were used to describe the climate at 477 cloud forest sites identified by United Nations Environment Program (UNEP)-WCMC. Some 85% of the sites are found at altitudes between 400 and 2800 m a.s.l., with an average altitude of 1700 m. The range of altitudes at which cloud forests are found is…

QTL for seed iron and zinc concentration and content in a Mesoamerican common bean (Phaseolus vulgaris L.) population
Department for International Development (DFID)
Abstract
Iron and zinc deficiencies are human health problems found throughout the world and biofortification is a plant breeding-based strategy to improve the staple crops that could address these dietary constraints. Common bean is an important legume crop with two major genepools that has been the focus of genetic improvement for seed micronutrient levels. The…

Putative storage root specific promoters from cassava and yam: cloning and evaluation in transgenic carrots as a model system
Department for International Development (DFID)
Abstract
A prerequisite for biotechnological improvements of storage roots is the availability of tissue-specific promoters enabling high expression of transgenes. In this work, we cloned two genomic fragments, pMe1 and pDJ3S, controlling the expression of a gene with unknown function from cassava (Manihot esculenta) and of the storage protein dioscorin 3 small…

Marker-Assisted Introgression of Resistance to Cassava Mosaic Disease into Latin American Germplasm for the Genetic Improvement of Cassava in Africa
Department for International Development (DFID)
Abstract
The gene pools for breeding cassava (Manihot esculenta Crantz) in Africa currently contain only a fraction of the existing genetic variation found in Latin America where the crop originates. Our research aimed to broaden the genetic base in Africa by introducing Latin American (LA) germplasm. The first set of introductions…

Development and GBS-genotyping of introgression lines (ILs) using two wild species of rice, O. meridionalis and O. rufipogon, in a common recurrent parent, O.�sativa cv. Curinga
Department for International Development (DFID)
Abstract
Two populations of interspecific introgression lines (ILs) in a common recurrent parent were developed for use in pre-breeding and QTL mapping. The ILs were derived from crosses between cv Curinga, a tropical japonica upland cultivar, and two different wild donors, Oryza meridionalis Ng. accession (…

Abiotic Stress Responses in Legumes: Strategies Used to�Cope with Environmental Challenges
Department for International Development (DFID)
Abstract
Legumes are well recognized for their nutritional and health benefits as well as for their impact in the sustainability of agricultural systems. The threatening scenario imposed by climate change highlights the need for concerted research approaches in order to develop crops that are able to cope with environmental stresses, while increasing yield and quality. During the last decade, some…

Variation in crude protein content in cassava (Manihot esculenta Crantz) roots
Department for International Development (DFID)
Abstract
Cassava roots are perceived as having relatively low protein content compared with other sources of energy (such as maize and wheat). This perception is in part due to a deficient screening in protein content levels in different cassava germplasm. For the current article, information on protein content of several cassava clones, gathered for a period of about 10 years, has been consolidated. Roots…

A global assessment using PCR techniques of mycorrhizal fungal populations colonising Tithonia diversifolia
Department for International Development (DFID)
Abstract
Tithonia diversifolia (Mexican sunflower) is a shrub commonly used as a green manure crop in Central and South America, Asia and Africa as it accumulates high levels of phosphorus and other nutrients, even in depleted soils. In root samples collected from the global distribution of Tithonia, we examined the degree of mycorrhizal colonisation and estimated the families of…
