Dilemma of nitrogen management for future food security in sub-Saharan Africa – a review
Food security entails having sufficient, safe, and nutritious food to meet dietary needs. The need to optimise nitrogen (N) use for nutrition security while minimising environmental risks in sub-Saharan Africa (SSA) is overdue. Challenges related to managing N use in SSA can be associated with both insufficient use and excessive loss, and thus the continent must address the ‘too little’ and ‘too much’ paradox. Too little N is used in food production (80% of countries have N deficiencies), which has led to chronic food insecurity and malnutrition.
Beyond “More Crop per Drop”: evolving thinking on agricultural water productivity
This Research Report chronicles the evolution of thinking on water productivity in the research agenda of IWMI and in the broader irrigation literature over the past 20 years. It describes the origins of the concept and the methodological developments, its operationalization through applied research, and some lessons learned over the two decades of research.

El manejo de plantas silvestres alimenticias en escenarios de deforestación, ilustrado por una comunidad mestiza de la Amazonía Peruana
Las plantas silvestres alimenticias son un componente esencial de la dieta de la población rural en distintas partes del mundo, teniendo un rol importante en su seguridad alimentaria y diversidad nutricional. Dada la alarmante disminución de los bosques, la colecta de estas especies ocurre cada vez más en ecosistemas antropogénicos, donde las comunidades activamente las manejan para asegurar su disponibilidad y acceso.

Linking crop structure, throughfall, soil surface conditions, runoff and soil detachment: 10 land uses analyzed in northern Laos
In Montane Southeast Asia, deforestation and unsuitable combinations of crops and agricultural practices degrade soils at an unprecedented rate. Typically, smallholder farmers gain income from “available” land by replacing fallow or secondary forest by perennial crops. We aimed to understand how these practices increase or reduce soil erosion. Ten land uses were monitored in Northern Laos during the 2015 monsoon, using local farmers' fields. Experiments included plots of the conventional system (food crops and fallow), and land uses corresponding to new market opportunities (e.g.
Foraging is determinant to improve smallholders’ food security in rural areas in Mali, West Africa
Studies on the enabling factors for household food security (HFS) most often used simplified econometric models looking into the links with a selected set of variables. In this research, a livelihood approach of HFS was used and aimed at determining the most significant livelihood assets for HFS in dryland agricultural systems. Elements of the five livelihood assets were assessed through questionnaire surveys with a random sample of 180 households, and six focus group discussions in three communities along the rural-urban continuum, in Southern Mali.
