The study relates village seed systems to biological diversity of millet crops grown by farmers in the semi-arid lands of Andhra Pradesh and Karnataka, India. In these subsistence-oriented, semi-arid production systems the environment is marginal for crop growth and often there is no substitute for millet crops. Across communities, farmers grow 13 different combinations of pearl millet, sorghum, finger millet, little millet, and foxtail millet varieties, but individual farmers grow an average of only 2–3 millet varieties per season.

Contract farming may be defined as agricultural production carried out according to a prior agreement in which the farmer commits to producing a given product in a given manner and the buyer commits to purchasing it. Often, the buyer provides the farmer with technical assistance, seeds, fertilizer, and other inputs on credit and offers a guaranteed price for the output. Proponents of contract farming argue that it links small-scale farmers to lucrative markets and solves a number of problems small-scale farmers face in diversifying into high-value commodities.

Private sector agricultural extension has expanded rapidly in many developing countries in the wake of drastic funding cuts made to public extension systems in the 1980s and 1990s. Motivated by the increase in sales or contract farming revenues that extension can generate, private providers include seed and input companies, distributors and dealers, service providers, food processors and retailers, and mobile phone companies. Mixed public-private systems are now becoming common. How well can the private sector fill the gap left by dysfunctional public systems?

To feed the world’s growing population, more food needs to be produced. In addition to cropland expansion, which faces a variety of constraints, increasing cropping intensity may provide a promising means of boosting global crop production. Yet information on the size and location of cropping intensity gaps—the difference between the maximum cropping intensity that is theoretically possible and the cropping intensity that is realized today—for current global croplands, and how much additional production can potentially be achieved by closing these gaps, is lacking.

Ethiopia’s agricultural sector has recorded remarkable rapid growth in the last decade. This paper documents aspects of this growth process. Over the last decade, there have been significant increases - more than a doubling - in the use of modern inputs, such as chemical fertilizers and improved seeds, explaining part of that growth. However, there was also significant land expansion, increased labor use, and Total Factor Productivity (TFP) growth, estimated at 2.3 percent per year.
