Harvesting prosperity through innovation and technology in agriculture

The history of early human advancement is the history of harvesting prosperity from agricultural innovation. In Harvesting Prosperity: Technology and Productivity Growth in Agriculture, we argue that this focus on raising agricultural productivity remains as urgent today as ever. Some stylized facts:

Globally, the vast majority of increases in output have been precisely through increases in Total Factor Productivity rather than expanding use of land or inputs. This is increasingly true for developing countries as well. However, this progress has been uneven across the different regions of the world. In particular, productivity growth has been low in some of the poorest regions, i.e. South Asia and Sub-Saharan Africa.  

Hence, understanding the determinants of productivity growth becomes central. One school of thought views the rural small holder sector as inefficient in resources use, a drag on development, and, hence, prevented from moving to more productive jobs by compromised factor markets. Harvesting Prosperity presents evidence that the gains from reallocating land and labor are probably smaller than often thought, but that there are great gains to be had from investments in the generation and diffusion of knowledge. It shows that a common, although conceptually flawed, measure of labor markets distortion, the gap in average labor productivities between agriculture and industry, when corrected by actual time spent in the field, effectively disappears. Theory suggests that efficiency demands that marginal productivities be equated and, in India, the report finds that the best proxy available, wages, are surprisingly similar across sectors. Similarly, recent work suggests that there are not great gains to be had by either breaking apart large holdings or consolidating small ones. Productivity growth can occur easily in both.

On the other hand, there does appear to be great potential gains for investment in knowledge generation and diffusion. As an example, estimates of rates of return to R&D in agriculture routinely fall between 30–40%, higher than many alternative investments. However, R&D as a share of agricultural GDP is 6 times higher in advanced countries than developing countries; R&D/worker is 50 times higher. Levels of real spending have been rising in China and parts of Asia but are falling in half of African countries. And this, exactly at a time when they face challenges on the poverty, food security and climate adaption fronts.

Hence, the focus is on how countries can close this research gap, as well as facilitate the adoption of new technologies by farmers. On the first count, in addition to better allocating state resources dedicated to the sector, the global emergence of private R&D providers offers potential to strengthen national R&D efforts. However, this demands establishing an enabling environment that is encouraging to such actors.

On the second point, recent research on the role of bias against agriculture, uncertainty, information asymmetries, weak human capital, poor access to product, insurance and financial markets suggests multiple failures that governments may need to tackle more or less simultaneously, in order to facilitate the adoption of these new technologies by farmers.

Another new actor — global value chains (GVCs) — offers both a way to expand markets and an alternative means of remedying market failures in a synchronized way than direct government interventions. Under the right conditions, GVCs offer credit, insurance and product markets for farmers affiliated with them. What is required is, again, an enabling environment that ensures profitability for the lead GVC firm, as well as a legal system that enforces contracts from firm to firm. For instance, if the lead firm provides fertilizer and credit, it wants to be sure that the final product, indeed, is sold to them.

The agenda to increase agricultural productivity and make the rural poor more resilient to the adverse shocks likely to prevail is as urgent as ever.  Fortunately, governments have new private sector actors and tools at their disposal if they embrace the necessary reforms.

Note: Harvesting Prosperity: Technology and Productivity in Agriculture is the fourth volume in the World Bank’s Productivity Project series, which examines the ‘productivity paradox’ of a persistent slowdown in productivity growth despite technological advancements.

I would like to request you to enrich us on possible World focus for integration of sustainable agricultural technologies & innovative ideas in relation to productivity growth. Connecting small & marginal farmers/ groups directly with fund facilities.

The major challenges of agriculture especially here in Nigeria is money. Am a lawyer by profession but i so much love farming especially poultry , fisheries etc.i graduated some years ago and very interested in pursuing my passion which is farming but no money.
My quest led me to some bank in Nigeria to access a loan but they refused on the ground that I ve no collateral and am also not a salary earner.these issue have frustrated so many graduate here in Nigeria
My candid advice is that the government should create an avenue were graduate
can access loan in Nigeria and elsewhere
Thanks

An interesting finding in the whole report is that small sized farms benefit as much from ICTs as large farms which is quite the opposite of previous WB publications. If true it is an important finding with policy implications for poor countries

William,

thank you for your thoughts on eliminating poverty among the majority of the World's poor. I like it because it is in line with some of my own thoughts on 'Bold Solutions' - http://www.nlgg.org/2019/05/26/bold-solutions-thinking-opportunity-cost….

Development Partners need to appreciate that for as long as we engage in subsistence approaches to eliminating poverty, the best we can hope for are subsistence savings; however, those kinds of savings cannot withstand against simultaneous shocks resulting into households perpetually living in poverty.

Innovation is about what hasn't existed before and perhaps its time we ventured out to try new ideas.

Thank you.
