Which of the following is NOT a research theme for ILRI?

The correct choice indicates that "Expansion" is not recognized as a primary research theme for the International Livestock Research Institute (ILRI). ILRI primarily focuses on research themes that directly relate to improving livestock and livestock systems, particularly in developing countries.

Agriculture is a central theme because it encompasses the study and improvement of livestock production systems, which are integral to food security and rural livelihoods. Health is also a significant research area, as ILRI conducts research that looks into human and animal health, especially in the context of zoonotic diseases and food safety. Gender is an important consideration in agricultural practices and development, and ILRI addresses gender issues to promote equitable benefits from livestock systems.

In contrast, "Expansion" does not align with the core themes associated with ILRI’s mission, which is focused on improving livelihoods and food security through livestock research rather than merely promoting expansion in a general sense. The exclusion of "Expansion" emphasizes the organization's targeted approach to specific themes that directly impact agricultural productivity, health outcomes, and gender equality in livestock systems.
