TIERRAS CULTIVABLES Y URBANIZACIÓN: UN ENFOQUE EMPÍRICO UTILIZANDO TÉCNICAS DE COINTEGRACIÓN Y DE CAUSALIDAD CON DATOS DE PANEL

The feeding is a basic condition for the correct development of the human being. Although the productive capacity of the planet can produce enough food for the entire population, there are still undernourished people who suffer from hunger. Efforts to eradicate hunger in the world do not seem to be enough, so it is worrisome that the demand for the 9 billion people projected in 2050 and increasingly concentrated in urban areas can not be met. To meet the demand for food it is necessary to have the right land for cultivation. Therefore, the objective of this research is to analyze the relationship between urbanization and arable land worldwide and by region, during the period 1961-2017. Through econometric techniques of correlation, regression, cointegration in the short and long term; and of Granger type causality, the relationship between both variables is measured in order to establish food security trends under the assumption that food production is linked to the use of arable land. The results show that urbanization affects arable land in a positive way both globally and by regions and that there is a relationship between the short and long term. However, in the latter, the co-efficient models of cointegration vectors showed a very weak force both in groups of countries and individually. Finally, Granger-type causality results showed unidirectional causality from urbanization to arable land only in the Middle East and North Africa; and South Asia, reaching the conclusion that urbanization does not reduce the use of agricultural land, on the contrary, it increases it in a smaller proportion.
