Background: The widespread insecticide resistance in malaria vector populations is a serious threat to the efficacy of vector control tools. As a result, the World Health Organization (WHO) supports the development of alternative tools that combine several insecticides with the aim of improving vector control and the management of insecticide resis...
Located at the northwestern part of the Amazon basin, Rio Negro is the largest black-water river in the world and is one of the poorest studied regions of the Amazon lowlands. In the middle-upper part of the Rio Negro were retrieved sediment cores form Lake Acarabixi, which were analyzed using pollen, spores, charcoal, and geochemistry. The aim of ...
Microfinance has played a key role in the fight against exclusion and the promotion of entrepreneurship in developing countries. An important question today is how to increase the reach and profitability of microfinance, in a context where subsidies are withdrawing to promote the viability and sustainability of microfinance institutions (MFIs). Eff...
Category 5 tropical cyclone Pam hit Vanuatu in March 2015, affecting thousands of people. Three months after the event, this study compared the responses from both external aid agencies and the disaster-affected communities to identify convergences, duplications and gaps. The research relies on 13 interviews with aid agencies and eight focus group ...
The priming effect in soil is proposed to be generated by two distinct mechanisms: 'stoichiometric decomposition' and/or 'nutrient mining' theories. Each mechanism has its own dynamics, involves its own microbial actors, and targets different soil organic matter (SOM) pools. The present study aims to evaluate how climatic parameters drive the inten...
The rapid expansion of perennial crops is a major threat to biodiversity in Southeast Asia. The biodiversity losses related to the conversion of forest lands to oil palm or rubber plantations (RP) are well documented by recent studies. However, the impact of the conversion from intensively managed annual crops to perennial crops on soil biodiversit...
This paper is a contribution to the understanding of surface dynamics of tropical shields over geological timescales. Emphasis is put on the fundamental and applied implications of regolith production and dispersion processes through the formation, dissection and preservation of landforms. It is based on the case study of sub Saharan West Africa, w...
Sustainable agriculture and agro-ecology justify the need to study and understand the role played by ecological processes, and soil biodiversity in particular, in agro-ecosystem functioning. A large number of studies have focused on earthworms in temperate and humid tropical ecosystems and have demonstrated their importance for improving soil biolo...
Objective: The objective was to learn what complications some women experienced in Madagascar following use of misoprostol for abortion and what treatment they received post misoprostol use. Study design: This was a qualitative study in 2015-2016 among women who had experienced complications after use of misoprostol, with or without additional meth...
