    This report offers an in-depth analysis of women’s roles and trade potential along the soybean-to-poultry value chain in the United Republic of Tanzania, within the context of the African Continental Free Trade Area (AfCFTA). Developed under the FAO–ITC joint programme Empowering Women and Boosting Livelihoods through Agricultural Trade (EWAT), the study highlights both opportunities and challenges facing women engaged in this sector.Drawing on a combination of quantitative trade data and qualitative insights from Tanzanian stakeholders, the report examines production, trade flows, market trends, and the structural features shaping the soybean-to-poultry chain. It emphasizes women’s critical yet often underrecognized participation in farming, processing, and small-scale poultry enterprises, while identifying key barriers such as limited access to finance, technical skills, and fair market conditions.The study situates the United Republic of Tanzania’s position within regional and global value chains, revealing how strategic investments and stronger linkages to regional trade could unlock new opportunities for women entrepreneurs. It underscores that for women to meaningfully benefit from the AfCFTA, targeted policy measures and institutional support are essential.The report concludes with actionable recommendations aimed at strengthening women’s economic empowerment, including improved access to inputs and markets, gender-responsive infrastructure, supportive business environments, and enhanced participation in decision-making. By promoting inclusive and sustainable trade-led growth, the AfCFTA holds the potential to transform the United Republic of Tanzania’s soybean-to-poultry sector into a driver of prosperity for women and communities alike.

    The effects of global value chain (GVC) participation on the economic growth of the agricultural and food sectors

    Trade liberalization has long been advocated as a means to foster growth and welfare. In developing countries, the expansion of global value chain (GVC) participation of agriculture and food sectors could support transformation from a subsistence-oriented and farm-centered system to a commercialized, productive and off-farm centered one. While empirical evidence examining the linkages between GVC participation and economic performance in the agricultural sector has traditionally relied on case studies at the product level, the availability of new aggregate data on trade in value added, now provides an unprecedented opportunity to carry out a global empirical assessment of the linkages. The present paper examines new measures of GVCs participation and positioning from the EORA panel data for the period 1995–2015 (Nenci, 2020) and tests their effects on changes in agriculture value added per worker. The results show that changes in GVC participation are, on average and ceteris paribus, positively associated with changes in agriculture value added per worker, net to time-invariant confounders, whereas mixed results are found on the effects of countries’ positioning along the value chain. In the conclusive remarks, the authors argue that import tariff and non-tariff barriers – including barriers to service trade – should be seen as the first obstacle to increase GVC participation and improve domestic value-added. The presence of signs of heterogeneity by geographical location confirms that general universal recipes do not exist.
