How important are smallholders?

The District of Uttarakannada in Karnataka State, India, has some wonderful farms. The rain shadow of the Western Ghats mountains and the powerful monsoon enable luxuriant growth of vegetation in this biodiversity hotspot.

Most farms in this district are very small, typically around one hectare in size, and very diverse. Tall areca palms, grown for the narcotic betel nut, form the overstorey, with vines of pepper and vanilla growing up their stems. The midstorey comprises nutmeg, cinnamon, banana, coconut, cocoa, cashew, mango, garcinia and sapota. In the understorey, we find coffee, pineapples, cardamom, ginger, and numerous vegetable crops. A small farm like this can support dozens of crops. A photograph of a field of maize

Contrast this with the giant maize monocultures of the American Midwest. The theory of economies of scale suggests that increasing the size of farms should make agriculture more efficient and profitable. Investments in technologies like tractors mean that farmers can manage more land with less labour. Research has shown that economy of scale does exist in agriculture, but only up to a point. In the USA, the maximum efficiency occurs at farms up to $500,000 in total annual sales. Conversion to monocultures makes farming even more efficient, because of easier harvesting and processing.

So with this in mind, we would expect small farms to get larger and less diverse over time. What are the global trends in farm size, and what are the implications for sustainable food systems? Many development organizations advocate the importance of “smallholders” or “family farms” for global food security, but with economies of scale, do smallholders actually want to increase the size of their business?

A recent analysis of published data found a total 570 million farms in 161 countries, of which 35 per cent are in China and 24 per cent in India. Since 1960, the average farm size has increased in the developed world, and decreased in the developing world. In India average farm size decreased from 2.7 to 1.3 hectares between 1960 and 2000, while in the USA average farm size increased from 122.6 to 178.4 hectares. Australian farms, characterized by livestock grazing on semiarid grasslands, have increased from an average of 1843.6 to 3243.2 hectares. In low income countries, the most land area (around one third) is in farms from 2-5 hectares in size, while in high income countries most land area (around a half) is in farms from 500-1000 hectares. So, in developing countries, smallholders hold the most land and the size of their farms is decreasing, while in developed countries, farms are large and economies of scale appear to be operating.

The term “family farm” is often used but not clearly defined – commonly it refers to farms managed by a family rather than a business. Globally, family farms account for around 75 per cent of agricultural area, while small farms (less than 2 hectares) account for just 12 per cent of agricultural area. So, smallholdings and family farms aren’t the same thing. In terms of global production, very small farms (less than 2 hectares) produce less than a quarter of all crops. The production diversity of small farms is important, however. Micronutrients and protein from crops are produced mainly in diverse production landscapes, where farm sizes are smaller. Crop production diversity is greatest in Southern Europe, East and West Africa, parts of India and China.

Farms of different sizes therefore provide different services to global food security. Large farms provide the major grains and commodity crops, while small farms maintain nutritional and genetic diversity. In 2019, the World Food Prize was awarded to Simon Groot, a seed developer. Groot, starting in the Philippines, developed high quality, disease-resistant seeds for small farmers in tropical countries. His work has allowed smallholders to produce more vegetables to bring to market, and made nutritious vegetables more available to millions of families in developing countries. This example demonstrates the importance of diversity in the food production system that smallholder farmers bring.
