Beans: a crop to invest in

From both an economic and nutritional perspective, the common bean is under-represented in the diets of low-income populations. This shortfall is reflected in high bean prices and chronic deficiencies in protein and key nutrients, seen across the developing world. Future demand for beans, meanwhile, is projected to increase, as incomes rise and rural-urban migration increases. Investment in the development of common bean varieties and value chains has the potential to offer substantial food security and economic benefits to these populations

Future bean demand

Bean demand is projected to rise sharply throughout the developing world, in tandem with rising populations, both in absolute terms and relative to other staple crops. The surge will be especially pronounced in Sub-Saharan Africa, where population is projected to surpass 2.5 billion by 2050

Improving bean yields

Breakthroughs in plant breeding at the CGIAR have placed bean yields on a 2%-3.3% per year growth trajectory based on experiment station trials, comfortably above minimum thresholds (set, for example, by the CGIAR Excellence in Breeding (EiB) platform) required to meet the dietary requirements of a global population projected to surpass 10 billion by 2050. These on-station gains must be extended to farmers' fields

Priority areas for investment in more sustainable and climate-resilient livestock systems

Livestock production supports economic growth, jobs and nutrition, but contributes to and is vulnerable to climate change. A transition is thus needed for livestock systems to become more sustainable and climate resilient, with clear positive effects on the Sustainable Development Goals. It is unclear, however, where the global community should invest to support this change. We identified priority geographies for livestock system investments in 132 low- and middle-income countries (LMICs), at mid- and low latitudes. Our results show that adaptation and mitigation goals are inextricably linked for the vast majority of these countries. An equal weighting of adaptation and mitigation indicators suggests that the top five investment priorities are India, Brazil, China, Pakistan and Sudan. Across LMICs, these act as critical control points for the livestock sector’s interactions with the climate system, land and livelihoods

Global drivers of food system (un)sustainability: A multi-country correlation analysis

At present, our ability to comprehend the dynamics of food systems and the consequences of their rapid ‘transformations’ is limited. In this paper, we propose to address this gap by exploring the interactions between the sustainability of food systems and a set of key drivers at the global scale. For this we compile a metric of 12 key drivers of food system from a globally-representative set of low, middle, and high-income countries and analyze the relationships between these drivers and a composite index that integrates the four key dimensions of food system sustainability, namely: food security & nutrition, environment, social, and economic dimensions. The two metrics highlight the important data gap that characterizes national systems’ statistics—in particular in relation to transformation, transport, retail and distribution. Spearman correlations and Principal Component Analysis are then used to explore associations between levels of sustainability and drivers. With the exception of one economic driver (trade flows in merchandise and services), the majority of the statistically significant correlations found between food system sustainability and drivers appear to be negative. The fact that most of these negative drivers are closely related to the global demographic transition that is currently affecting the world population highlights the magnitude of the challenges ahead. This analysis is the first one that provides quantitative evidence at the global scale about correlations between the four dimensions of sustainability of our food systems and specific drivers

Fertilizer prices in Sub-Saharan Africa

We compiled fertilizer price data for eighteen countries in West and East Africa from two data sources: (1) Africa Fertilizer (Africa Fertilizer, 2018) and (2) the Living Standards Measurement Study-Integrated Surveys on Agriculture (henceforth LSMS-ISA) (World Bank, 2018). Africa Fertilizer reports prices over time for major towns in different countries. Prices are for 25 kg or 50 kg bags and expressed in the national currency. We compiled 7823 observations for 878 locations in seventeen countries: Benin, Burundi, Burkina Faso, Côte d’Ivoire, Ghana, Kenya, Mali, Malawi, Mozambique, Niger, Nigeria, Rwanda, Senegal, Togo, Tanzania, Uganda, and Zambia from 2010-2018. We used the town name to assign geographic coordinates to each location. Africa Fertilizer reported non-subsidized and subsidized prices for several countries. LSMS-ISA is a nationally representative multi-topic household survey implemented in eight countries in SSA: Burkina Faso, Ethiopia, Malawi, Mali, Niger, Nigeria, Tanzania, Uganda (World Bank, 2018)
