Debate on agricultural trade can be traced back from the negotiations on agricultural trade under the General Agreement on Tariffs and Trade, which came into force in 1948. Later, significant progress toward agricultural trade reforms were covered and continues to be negotiated upon by the World Trade Organization Agreement on Agriculture, which came into force in 1995 as a result of the 1986-1994 Uruguay Round of world trade negotiations supported by the General Agreement on Tariffs and Trade (WTO, 2016). Since 1994, agricultural trade has been liberalized, which has led to increased globalization and integration. World Trade Organization members commit themselves to general agricultural trade rules pertaining to market access, domestic support, and export competition within well-defined timelines. The ultimate goal of these negotiations is to improve the livelihoods of farmers around the world through implementing sound agricultural trade regulations and domestic policies that promote competition and reduce distortions in agricultural trade (WTO, 2016). The research on agricultural trade and economic growth has therefore been gaining attention in the recent past both in developed and developing countries.Most countries in sub-Saharan Africa (SSA) are agriculture-based, and agriculture accounts for about 32% of their Gross Domestic Product (GDP) on average (World Bank, 2008). In addition, more than 65% of the total population in the region is employed in the agriculture sector, although Africa in general has recently been experiencing rapid agricultural exits particularly in oil-producing countries (Headey et al., 2010). Nevertheless, Africa's agriculture has the potential to reduce rural and urban poverty, which explains why boosting agriculture productivity remains a critical priority (Mozumdar, 2012). In SSA, the sector's production remains relatively low compared with other regions in the world. Agriculture total factor productivity in SSA has been generally low and highly volatile, with an annual growth rate ranging between −0.05 and +0.05 for both low-and middle-income countries for the period 1962-2015 (USDA 2019). Stagnation in agriculture productivity in the region has resulted in low agricultural output and consequently low global share of Africa's agricultural
