Policy Issue: 

Agricultural productivity has stagnated in much of sub-Saharan Africa, while many other regions of the world have seen dramatic productivity improvements in recent decades. New agricultural technologies, such as high-yielding crop varieties, offer the promise of improving productivity and hence the welfare of farmers. But adoption of these technologies has often been low in countries where dissemination programs have been conducted. First adopters of new technologies play an important role in the spread of technology as they take on the burden of experimentation—testing whether and how a new variety works in local conditions. This is particularly important in much of sub-Saharan Africa where a multiplicity of micro climates within a small area means that experimentation is essential for farmers to learn which crop varieties are best for their particular land. There is also concern that early subsidization to increase adoption of new technologies will lead to expectation of continued subsidies, depressing demand at market prices.

Details of the Intervention: 

Researchers sought to test whether improved seeds are beneficial for the poor in Sierra Leone and how best to promote uptake given the high costs of early adoption. Early adopters generate positive externalities to surrounding farmers and communities by delivering information on the effectiveness of new varieties and how to make the most of them in local conditions.

In 2011, a random sample of 5 farmers in each of 36 communities received half a bushel of NERICA-3, a short-duration variety of rice with the potential for high yields. These farmers also received regular visits from agricultural extension workers who provided practical advice on how to cultivate these seeds.

In 2012, researchers will test a more complex set of incentives that includes: (1) a price subsidy scheme allowing farmers to purchase new seeds at lower than market price, and (2) provision of targeted agricultural extension work involving community demonstration plots. The second year of the intervention will include four treatment arms, each with approximately 40 communities under three different schemes:

Pricing Scheme:

  • T1: Farming households offered NERICA-3 variety at 0 percent subsidy (market price)
  • T2: Farming household offered NERICA-3 variety at 50 percent subsidy.
  • T3: Farming households offered NERICA-3 variety at 100 percent subsidy (free)

ROK-16 Scheme:

  • T4: Farmers are offered ROK-16 at 100 percent subsidy (free)

Training Scheme:

  • Each of these four treatment groups are cross-cut so that half of the communities in each treatment group will receive a targeted training program intended to assist the farmer in adapting to the cultivation techniques specific to the new variety of rice they acquired.

The pricing scheme aims to test the hypothesis that a one-time subsidy can reduce the adoption cost for early-adopters and have a long-lasting effect on both the beneficiary and their neighbors. The training scheme aims to reduce the cost of learning by providing information on how well the seed works in the community (through a demonstration plot) and on how to cope with some of the features specific to the new variety of rice.

In 2013, ten farmers from the 160 treatment communities as well as ten farmers from an additional 40 control communities will be offered the chance to purchase NERICA-3 at full market price without targeted access to extension work. Key outcome variable to be measured at the endline include: (1) the amount of improved rice variety seeds (NERICA-3 and ROK-16) purchased and planted; (2) the impact of subsidies and training on purchasing decisions in subsequent years; (3) planting of other rice varieties and other crops; (4) yields, consumption, and food security

Results and Policy Lessons: 

Study in implementation, results forthcoming.
