Which of the following is NOT a research theme for the International Livestock Research Institute (ILRI)?

The International Livestock Research Institute (ILRI) focuses on several key research themes that align with their mission to improve food security and reduce poverty in developing countries through livestock research. The themes of environment, food, and gender are integral to understanding the multifaceted role livestock plays in various ecosystems and communities.

The environment theme addresses the interactions between livestock and natural resources, exploring sustainable practices that decrease the environmental impact of livestock production. The food theme is centered on enhancing food systems to ensure that livestock products contribute effectively to food security and nutrition, which are critical for health and economic well-being. Gender is a theme that considers the roles and contributions of women and men in livestock production systems, highlighting the importance of equitable access to resources and opportunities in improving livelihoods.

In contrast, "expansion" does not specifically align with the recognized research themes of ILRI. While growth and expansion may be relevant to discussions about the livestock sector and its development, they are not defined research focuses of the institute. Instead, the research themes are more concrete and aimed at addressing specific challenges and opportunities in livestock systems globally. Therefore, the identification of expansion as not being a recognized research theme aligns with ILRI's strategic priorities and research framework.
