There is a classic debate in agricultural economics and development policy about the relative efficiencies of small and big farms. It is centred on what is known as the 'inverse relationships' which posits that as farms become smaller they become more productive per unit area, as costs – such as the supervision of labour – get reduced (or at least passed on to cheaper family labour arrangements). The argument is that small farms are the ideal, efficient solution to agricultural production.
Of course there are qualifications – and these are important, perhaps increasingly so in a globalised world. Very small farms, fragmented in different ways, are clearly not ideal, and suffer from many inefficiencies. Yet, what is 'small' and 'very small' is often not clear in the literature. Equally, there may be economies of scale in certain production-marketing systems, making larger farms more efficient. For example, getting high value products into international markets may mean complying with quality standards which small farmers would find difficult to adhere to.
