the scenario. In total, the non-agricultural sectors modeled with high TFP growth account<br />

<strong>for</strong> slightly less than 40 percent of national income <strong>for</strong> SSA, almost double the share of<br />

agriculture in SSA total GDP (20 percent). 43<br />

The simulation results illustrate the importance of demand effects and the interlinkages<br />

between agriculture and non-agriculture. Improving growth per<strong>for</strong>mance of<br />

manufacturing and private services not only boosts total GDP (up 20 percent in year 12<br />

and 1.51 percent per capita annually), but also allows spurs agricultural growth through<br />

increased demand <strong>for</strong> agricultural products. Regional real agricultural GDP increases by<br />

42 percent in year 12, equivalent to a 2.97 percent per capita annual growth rate. Total<br />

food consumption increases by 30 percent per capita in year 12 (a 2.2 percent per capita<br />

annual growth rate, faster than growth rate of total GDP). Agricultural exports are also<br />

stimulated, up 95 percent in year 12, (a 5.7 percent per capita annual growth rate).<br />

The 4 percent TFP annual growth in selected manufacturing and services in the<br />

model may be overly optimistic given investment, technology, and institutional<br />

constraints that inhibit growth in SSA. Such cross-sector growth linkages can be induced<br />

by increased investment and improved production efficiencies in agriculture, especially<br />

in exportable non-traditional agriculture, or can be a result of investment directly in<br />

labor-intensive non-agriculture, such as textile and trade-related private services. Though<br />

the mechanisms <strong>for</strong> achieving high productivity growth in non-agriculture are not<br />

specified, this scenario does highlight the role of demand constraints on agricultural<br />

growth and the importance of growth in non-agriculture <strong>for</strong> achieving growth in total<br />

income.<br />

h. At the country and sub-regional levels, non-traditional agricultural exports may<br />

have larger growth effects<br />

The above analysis is based on the model simulation results <strong>for</strong> SSA as a whole.<br />

When we further look at the effects in a single country or a sub-region under the same<br />

43 The structure of national economies differs by country, however. For South Africa, Malawi, and<br />

Mozambique, the share of these non-agricultural sectors in GDP is higher (40 to 45 percent), while<br />

agriculture’s share of GDP is 7, 37, and 35 percent, respectively. For Uganda, however, the nonagricultural<br />

sectors modeled with high TFP growth account <strong>for</strong> less than 20 percent of GDP, while<br />

agriculture accounts <strong>for</strong> more than 50 percent.<br />
