In many parts of Asia food security and poverty remain issues even though arable land is available to produce nutritious food. Sustainable intensification of agricultural systems has been proposed to produce more outputs on same land area whilst minimizing environmental degradation. Tradeoffs, ho...

Sustainable intensification of rice-based systems with potato in eastern indo-gangetic plains.
Achieving and maintaining global food security is challenged by changes in population, income, and climate, among other drivers. Assessing these threats and weighing possible solutions requires a robust multidisciplinary approach. One such approach integrates biophysical modeling with economic mo...

Structural approaches to modeling the impact of climate change and adaptation technologies on crop yields and food security
This article examines how the estimated impacts of crop technologies vary with alternate methods and assumptions, and also discusses the implications of these differences for the design of studies to inform research prioritization. Drawing on international potato research, we show how foresight s...

Comparing modeling approaches for assessing priorities in international agricultural research
Potato is the most important non-grain crop in the world. Therefore, understanding the potential impacts of climate change on potato production is critical for future global food security. The SUBSTOR-Potato model was recently evaluated across a wide range of growing conditions, and improvements ...

The widely recognized role of roots, tubers and bananas (RT&Bs) in achieving food security and providing income opportunities in the world’s poorest regions will be challenged by socioeconomic and climate related drivers. These will affect demand and production patterns and increase pressure on f...

Understanding the consequences of changes in the production frontiers for roots, tubers and bananas.
A few studies have reported some of the costs associated with bringing to market genetically-modified (GM) crops but no comprehensive studies exist on the real cost of the entire process of developing and releasing one GM variety by a not-for-profit institution in a developing country for sustain...

Technical and economic analysis of aeroponics and other systems for potato mini-tuber production in Latin America.
Innovations to improve staple crop germplasm can reduce poverty and otherwise improve farmer livelihoods through complex and multiple pathways. This paper reviews the evidence for one prominent pathway—through increased incomes (in cash and kind) for poor farmers who adopt the technology.
