Fertilizer and conflicts: Evidence from Myanmar

The number of farmers residing in fragile and conflict-affected countries is rising globally, yet the impacts of conflict on the economics of inorganic fertilizer in these settings remain poorly understood. We study how conflicts in Myanmar, combined with global fertilizer market disruptions, have affected inorganic fertilizer prices, use, response, and efficiency. We utilize unique nationally representative household panel survey data and a comprehensive approach that employs various analytical methods to examine the nexus between conflicts and fertilizer-related issues. Our findings reveal that greater intensity of violent events is associated with higher prices of major types of inorganic fertilizer, particularly in areas farther from major import locations. These price changes and increases in violent events have suppressed both the likelihood and quantity of inorganic fertilizer usage, leading to decreased rice yield responses at given nitrogen application levels. Panel stochastic frontier analyses, combined with a method addressing the endogeneity of inorganic fertilizer use, suggest a significant decline in fertilizer use efficiency each year since the onset of conflict. The increase in violent events is also associated with the reduced use of extension services, seeds from markets, irrigation, and optimal fertilizer blends, which may partly explain the diminished returns and efficiency of inorganic fertilizer use. Conflict therefore seems to be associated with a change in the economics of inorganic fertilizer use through various impact channels, affecting agricultural performance in these fragile and conflict-affected settings.

Characteristics of community seed schemes for grains and legumes: Insights from northern Nigeria

CONTEXT: Despite the significant roles that intermediary seed systems play in the supply of quality seeds in developing countries, including Africa south of the Sahara, the knowledge gap remains generally substantial regarding the general characteristics and seed quality control performance of intermediary seed systems such as community seed schemes (CSS), which still operate predominantly outside the formal seed systems. OBJECTIVE: We aim to narrow the knowledge gap on seed production practices implemented by CSS, their economic and technical characteristics, the extent of seed quality control achieved, and potential challenges CSS is facing. METHODS: Using primary survey data of seed producers of key grains (maize, rice, and sorghum) and legumes (cowpea and soybean) from 380 CSS in Kano state in northern Nigeria, we qualitatively assess origins and drivers of their growth, extent of seed production, relations with upstream actors (breeder and foundation seed providers) and downstream actors (seed buyers), economic structures of their seed production, aspects of quality control measures they engage, and potential roles of external support, such as training on the implementation of these quality control measures. RESULTS AND CONCLUSIONS: We discovered that many of the interviewed CSS have emerged endogenously, taking up seed production to address the challenges in access to quality seeds in their locality. Their seed production has often grown into viable businesses that have provided potentially significant additions to their incomes. Oftentimes, these CSS implemented some seed quality control measures, including making closer visual checks of seeds, checking germination rates, and bagging/packing seeds, among others. However, fuller seed quality control may be significantly skill-intensive, and most CSS still do not implement many of the recommended measures under some of the intermediary quality assurance standards, such as Quality Declared Seed. Our qualitative assessment suggests that future support for CSS can focus on technical support to raise the ability to engage in broader categories of quality assurance activities in economically viable ways and to improve the awareness and knowledge of different varieties and access to foundation seeds. SIGNIFICANCE: The quality assurance provided by existing CSS in Nigeria may be relatively limited, particularly in proper maintenance of the seed production field and the quality of original seeds that CSS intend to multiply. Providing external support through training and technical assistance can be an effective way to transform community seed schemes into critical providers of seed quality assurance in the intermediate seed system and to fill gaps in the formal seed system.
