Global modeling of the socioeconomic, political, and environmental relations of farmer seed systems (FSS)
Accessible, high-quality seed is vital to the agricultural, food, and nutrition sovereignty needed for justice-based sustainable development. Multiregion, interdisciplinary research on farmers’ seed systems (FSS) can complement case-based and thematic approaches. This study’s goals are to (1) provide a synthetic overview of current major FSS concepts; (2) design and evaluate a novel social- and political-ecological model of FSS using globally rep…
Revisiting the adequacy of the economic policy narrative underpinning the Green Revolution
The Green Revolution still exerts an important influence on agricultural policy as a technology-centred development strategy. A main policy narrative underpinning the Green Revolution was first expounded in Transforming Traditional Agriculture ( TTA ), a book published in 1964 by Nobel Prize-winning economist Ted Schultz. He famously argued that traditional farmers were ‘poor but efficient’. As farmers responded to economic incentives, technology…

Por qué se pierde la agrobiodiversidad
En esta investigación se analizaron las causas sociales, ambientales y económicas que inciden en la pérdida de agrobiodiversidad de las chagras del pueblo indígena Inga en la Amazonía colombiana. Se usó una metodología cualitativa basada en entrevistas semiestructuradas, grupos focales y asambleas para validación de información. Los resultados muestran que la pérdida de la agrobiodiversidad se debe principalmente a cambios en los paradigmas de co…
Climate risk management and rural poverty reduction
Climate variability is a major source of risk to smallholder farmers and pastoralists, particularly in dryland regions. A growing body of evidence links climate-related risk to the extent and the persistence of rural poverty in these environments. Stochastic shocks erode smallholder farmers' long-term livelihood potential through loss of productive assets. The resulting uncertainty impedes progress out of poverty by acting as a disincentive to in…
Are agricultural researchers working on the right crops to enable food and nutrition security under future climates
This study examined how crop-specific agricultural research investments can be prioritised to anticipate climate change impact on crops and to enable the production of more nutritious food. We used a simple crop modelling approach to derive expected future changes in regional climate suitability for crops. To determine if different starch-rich and pulse crops are currently underresearched or overresearched, we examined the global relation between…
Emergency drills for agricultural drought response
Drills are an important element of disaster management, helping to increase preparedness and reduce the risk of real‐time failure. Yet, they are not applied systematically to slow‐onset disasters such as a drought, which causes damage that is not instantly apparent and thus does not solicit immediate action. This case study evaluates how drills inform institutional responses to slow‐onset disasters. It spotlights Guatemala, a country where drough…
Climate‐Smart Landscapes
Addressing the global challenges of climate change, food security, and poverty alleviation requires enhancing the adaptive capacity and mitigation potential of agricultural landscapes across the tropics. However, adaptation and mitigation activities tend to be approached separately due to a variety of technical, political, financial, and socioeconomic constraints. Here, we demonstrate that many tropical agricultural systems can provide both mitig…
The contribution of rice agriculture and livestock pastoralism to prehistoric methane levels
We review the origins and dispersal of rice in Asia based on a data base of 443 archaeobotanical reports. Evidence is considered in terms of quality, and especially whether there are data indicating the mode of cultivation, in flooded (‘paddy’ or ‘wet’) or non-flooded (‘dry’) fields. At present it appears that early rice cultivation in the Yangtze region and southern China was based on wet, paddy-field systems from early on, before 4000 bc, where…
Crowdsourcing Crop Improvement in Sub-Saharan Africa
In sub-Saharan Africa, modern varieties released by the formal seed sector cover only a small part of the total crop acreage. Participatory approaches to crop improvement and seed production have been developed to overcome some of the barriers to modern variety development and seed distribution, but have not been widely scaled up. Crowdsourcing, such as seen in online citizen science projects, might inspire new approaches to upscale farmer-partic…
Consilience of genetics and archaeobotany in the entangled history of rice
Environmental destruction as a counterinsurgency strategy in the Kurdistan region of Turkey
Images of war
In areas of war and armed conflict it is difficult to get trustworthy and coherent information. Civil society and human rights groups often face problems of dealing with fragmented witness reports, disinformation of war propaganda, and difficult direct access to these areas. Turkish Kurdistan was used as a case study of armed conflict to evaluate the potential use of satellite images for verification of witness reports collected by human rights g…

Molding maize
Changes in farmers' knowledge of maize diversity in highland Guatemala, 1927/37-2004
Small-scale studies on long-term change in agricultural knowledge might uncover insights with broader, regional implications. This article evaluates change in farmer knowledge about crop genetic resources in highland Guatemala between 1927/37 and 2004. It concentrates on maize (Zea mays ssp. mays L.) in one Guatemalan township, Jacaltenango, an area with much ecological and maize diversity. It relies on a particular type of baseline information: …
