All these put together  and harnessed determine both agricultural  and economic growth in Africa. This was the submission of Dr Guy Blaise Nkamleu, IITA Yam Economist, at a recent seminar as part of a routine scientific forum in the Institute.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Titled: \u201cDisentangling the sources of growth \u2013 l and, labor, fertilizer, tractor, research, extension \u2026 what are their exact contributions to agricultural growth in Africa: lessons from macro-data\u201d, the seminar was aimed at investigating sources  and determinants of agricultural output in association with growth in physical  and nonphysical factors, with the attendant focus on how much output growth is due to technology, productivity improvement, efficiency change  and other production factors\u2019.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dr Nkamleu drew the attention of the audience to some salient questions on agricultural growth. He queried why some African countries had rapid economic growth, while others experience economic stagnation  and regression under the same conditions. Furthermore, he sought to know how African countries could achieve now what they could not achieve in the past 30 years. To remedy the situation, Dr Nkamleu said the driving forces affecting African agricultural growth must be explored  and acted upon.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">His presentation provided a quantification of the contribution of different inputs in the agricultural growth,  and highlights the fact that input accumulation accounts for a large share of agricultural output growth  and fertilizer has been the most important physical input contributor to agricultural growth. He also highlights the extent to which agricultural growth contributors vary across countries  and regions in relation with different country conditions, institutions  and politico-historical factors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThese findings have important implications for research  and show types  and the extent of interventions needed to be put in place in each region\/countries for enhancing the agricultural growth of African agriculture\u201d, Dr Nkamleu said.<\/p>","protected":false},"excerpt":{"rendered":"<p>The potential sources of agricultural growth are land, agrochemicals, labor quantity, labor quality, tractors, livestock, technology, and random factors.
