Cassava germplasm strategies for Africa por Allem, A.C., Hahn, S.K.

“…The topic of genetic erosion is also addressed; there is no tangible evidence, however, that cassava is undergoing serious genetic erosion in its centers of origin (American neotropics). Major cassava germplasm collections are listed for the Americas, Africa, and Asia. …”

Physic nut, Jatropha curcas L. por Heller, J.

“…This tropical crop is native to Mexico and Central America, but is cultivated in many other Latin American, Asian and African countries as a hedge. It has become of interest to various development agencies because it adapts well to semiarid marginal sites, its oil can be processed for use as a diesel fuel and it can be used for erosion control.This monograph has chapters covering the following aspects of J. curcas: names of the species and taxonomy; botanical description; origin and centre of diversity; properties (toxicology); uses (whole plant and food/fodder, medicine, plant protectant and molluscicide, technical uses, diesel fuel and other uses); genetic resources (existing genetic variation, conservation); breeding (objectives, method and selection based on provenance trials); production areas; ecology; agronomy (growth and development, propagation methods and pests and diseases); limitations of the crop; prospects; and research needs.There are appendices listing (I) research contacts, centres of crop research, breeding and plant genetic resources of physic nut and (II) publications of Proyecto Biomasa, DINOT/UNI, Nicaragua. …”

Seeding resilient restoration: An indicator system for the analysis of tree seed systems por Atkinson, Rachel J., Thomas, Evert, Roscioli, Federico, Cornelius, Jonathan P., Zamora-Cristales, Rene, Franco Chuaire, Maria, Alcázar Caicedo, Carolina, Mesén, Francisco, López, Hariet, Ipinza, Roberto, Donoso, Pablo J., Gallo, Leonardo, Nieto, Victor, Ugarte, Julio, Sáenz Romero, Cuauhtémoc, Fremout, Tobias, Jalonen, Riina, Gaisberger, Hannes, Vinceti, Barbara, Valette, Michel, Bosshard, Ennia, Ekué, Marius, Wiederkehr Guerra, Gabriela Patricia, Kettle, Christopher J.

“…We propose 15 indicators to evaluate these key components and trial them by assessing national seed systems in 7 Latin American countries. We conclude that the indicators enable a straightforward assessment of the strengths and weaknesses of national seed systems, thus assisting governments to identify key areas for improvement and opportunities for horizontal learning.…”

Discovery and characterization of sweetpotato’s closest tetraploid por Muñoz Rodríguez, P., Wells, T., Wood, J.R.I., Carruthers, T., Anglin, N.L, Jarret, Robert L., Scotland, R.W.

“…We integrate morphological, phylogenetic, and genomic analyses of herbarium and germplasm accessions of the hexaploid sweetpotato, its closest known diploid relative Ipomoea trifida, and various tetraploid plants closely related to them from across the American continent. We identify wild autotetraploid plants from Ecuador that are morphologically distinct from Ipomoea batatas and I. trifida, but monophyletic and sister to I. batatas in phylogenetic analysis of nuclear data. …”

Urbanization in Latin America: constraints and opportunities for child feeding and care por Ruel, Marie T.

“…The phenomena that are unique to urban life and that are likely to have an impact on child-care and feeding practices are reviewed using data from DHS for six Latin American countries. The issues examined include the higher levels of education and of labour force participation of urban women, the larger percentage of women who head households, and the potentially different family structure and social networks, which may affect the availability of substitute child care. …”
