Through this article, the results of the Free Trade Agreement between Colombia and the United States were addressed, based on its effects on the exports of the Colombian agricultural sector and its repercussions on the rural microeconomy, using the following methods: a) Descriptive b) Comparative Method c) Revealed Comparative Advantages (RCA) and d) Prospective Approach, being the main variables, competition, rural poverty in Colombia, concentration of rural property and the investment budget destined for the vulnerable agricultural sector, observing that Colombia's agricultural products do not have significant comparative advantages to compete with the North American market, which is evidenced in the deficit trade balance. Colombia is the most unequal country in the distribution of land in Latin America where the largest extensions are destined to the production of agrofuels and it is the small farmers who generate the largest number of crops for internal consumption, persisting despite the hostile conditions in the Colombian countryside, and the high rates of monetary and multidimensional poverty. These circumstances pose a risk to the country's food sovereignty by becoming dependent on imports, which is why a legal-economic proposal was made for Colombia based on the United Nations Declaration of the Right to Development.
