英文文献摘要：
Agriculture is something more than crops and food: nowadays all countries regard it as a strategic asset. Agriculture's performance and its contribution to our countries' economic development has traditionally been undervalued, since it is measured using information about harvests and the sale of raw materials, mainly crops and livestock. As a result, the backward and forward linkages with agro-industry, the services and trade sectors and, in general, the rest of the economy, are undervalued. The aim of this study was to develop a methodology to estimate agriculture's true contribution to economic development for 11 countries in the Americas. This methodology empirically addresses the concept of extended agriculture; calculates agricultural linkages; and simulates the impact of agriculture on the countries' overall economic activity.
