Previous issue date: 2017-06-12 === Agriculture is one of the activities that has impacted the environment more current day; Producing food in ways that reduce the impact of nature is a challenge to be overcome. The agroforestry system is an alternative of agricultural production associated to the cultivation of trees that reduce the devastation of nature. Through this research, possibilities of minimizing environmental impacts in agriculture were studied, based on the use of mathematical knowledge. This research has a qualitative approach, initially consisted of the application of questionnaires with open and closed questions to ten teachers and twenty students of a Technical Course in Agropecu?ria Integrated to High School in Par? Federal Institute of Education, Science and Technology, Marab? Rural Campus. During the development of the research several educational practices were carried out; In these activities, the students participated actively and in the end the action and its importance in the agricultural context was reassessed, always trying to enable those involved to perceive the importance of the knowledge built in the school in the daily activities. The objective was to investigate the view of both regarding the importance of educational practices developed in the agricultural context and the use of mathematical knowledge to reduce the damage caused to nature, particularly the agroforestry system. The results point to the importance of mathematics contents, articulated with the other areas of the curriculum, in the search for alternatives that reduce the environmental impacts on agricultural activity. === A agricultura ? uma das atividades que mais tem impactado o meio ambiente nos dias atuais. Produzir alimentos de forma que reduza o impacto causado a natureza ? um desafio a ser superado. O sistema agroflorestal, ? uma alternativa de produ??o agr?cola associada ao cultivo de ?rvores que reduzem a devasta??o da natureza. Atrav?s desta pesquisa, foram estudadas possibilidades de minimizar os impactos ambientais na agricultura, a partir do uso do conhecimento matem?tico. Esta pesquisa tem abordagem qualitativa, consistiu inicialmente na aplica??o de question?rios com perguntas abertas e fechadas a dez docentes e vinte discentes de um Curso T?cnico em Agropecu?ria Integrado ao Ensino M?dio do Instituto Federal de Educa??o, Ci?ncia e tecnologia do Par?, Campus Rural de Marab?. Durante o desenvolvimento da pesquisa v?rias pr?ticas educativas foram realizadas; nessas atividades os estudantes participavam ativamente e ao final foi reavaliada a a??o e a sua import?ncia no contexto agr?cola, procurando sempre possibilitar que os envolvidos percebessem a import?ncia dos conhecimentos constru?dos na escola nos afazeres do cotidiano. O objetivo foi investigar a vis?o de ambos em rela??o a import?ncia de pr?ticas educativas, desenvolvidas no contexto agr?cola, e o uso dos conhecimentos matem?ticos para a redu??o dos danos causados ? natureza, em particular ao sistema agroflorestal. Os resultados apontam para a import?ncia dos conte?dos de matem?tica, articulado com as demais ?reas do curr?culo, na busca de alternativas que reduzam os impactos ambientais na atividade agr?cola.
