Previous issue date: 2014-02-26 / A agricultura ? um dos temas mais discutidos atualmente dentro do campo conceitual da sustentabilidade. Os debates s?o cada vez mais recorrentes e colocam em quest?o, o modelo adotado a partir p?s-guerra, denominado de revolu??o verde, pelo seu potencial de degrada??o dos recursos naturais. Esse tipo de agricultura colocou o Brasil no topo do agroneg?cio mundial, aonde se destaca em diversos setores como o de gr?os, carne, a??car e tamb?m na fruticultura. As discuss?es est?o voltadas para aspectos relacionados ao uso de agroqu?micos, monocultivo, convers?o de florestas nativas em extensas ?reas agr?colas, dentre outros pontos tidos como delet?rios ao equil?brio ambiental. Por outro lado, encontra-se um modelo, denominado de agricultura familiar, que para muitos pesquisadores, possui atributos mais pr?ximos do entendimento de agricultura sustent?vel. No estado do Rio Grande do Norte, o potencial agr?cola reside principalmente na fruticultura, aonde se destaca o agropolo A?u-Mossor?, como uma das principais regi?es produtoras de frutas tropicais do Brasil, sendo o mel?o o principal fruto produzido. O cultivo desta oler?cola desenvolveu-se na regi?o no final da d?cada de 1980, a partir do investimento de grandes empresas agr?colas, cujas t?cnicas de cultivo eram pautadas pela revolu??o verde. Atualmente, o cultivo do mel?o ? tamb?m desenvolvido em agroecossistemas cuja gest?o ? caracterizada pela participa??o familiar, inclusive em assentamentos rurais criados pelo Instituto Nacional de Coloniza??o e Reforma Agr?ria (INCRA). Diante desta inser??o da agricultura familiar num campo em que a pouco era dominado por grandes empresas agropecu?rias, surgem quest?es relativas a manuten??o dos atributos que caracterizam essa modalidade de gest?o agr?cola. O presente trabalho objetivou a avalia??o da sustentabilidade de agroecossistemas familiares do assentamento S?o Rom?o em Mossor?-RN, cultivados com mel?o. O estudo foi realizado a partir da utiliza??o da estrutura do Marco para Avalia??o de Sistemas de Manejo de Recursos Naturais Incorporando Indicadores de Sustentabilidade (MESMIS), em dez agroecossitemas do assentamento. Os dados foram obtidos a partir da realiza??o de entrevistas semi-estruturadas e observa??es de campo, de forma que as respostas, considera??es e coment?rios realizados pelos assentados foram amplamente aproveitados para percorrer os seis passos do ciclo avaliativo do MESMIS. Foram determinados sete pontos cr?ticos que afetam a sustentabilidade, sendo: recursos h?dricos, solos, depend?ncia de insumos externos, biodiversidade, qualidade de vida, rendimento familiar e organiza??o comunit?ria, a partir dos quais derivaram vinte e tr?s indicadores que buscaram refletir o real estado de sustentabilidade dos agroecossistemas. / Agriculture is one of the most discussed topics currently in the conceptual field of
sustainability. The debates are increasingly recurrent and put in question the model adopted
from post-war, so-called green revolution, for its potential of degradation of natural resources.
This type of Agriculture put Brazil at the top of the global agribusiness, where stands out in
various sectors such as grain, meat, sugar and horticulture. Discussions are focused on aspects
related to the use of agrochemicals, monoculture, conversion of native forest in extensive
agricultural areas, among other points taken as deleterious to environmental balance. On the
other hand, there is a model, called by family farming, which for many researchers, has
attributes closer to the understanding of sustainable agriculture. In the state of Rio Grande do
Norte, the agricultural potential lies mainly on horticulture, where stands the agropolo AcuMossor?,
as one of the greatest tropical fruit producing regions of Brazil, being melon, the
major fruit produced. The cultivation of this vegetable was developed in the region in the late
1980s, from the investment of large agricultural enterprises, whose cultivation techniques
were grounded by the green revolution. Currently, the melon cultivation is also developed in
agroecosystems whose management is characterized by family participation, including small
farmers of rural settlements created by Instituto Nacional de Coloniza??o e Reforma Agr?ria
(INCRA). In view of the inclusion of family farming in a field that recently was dominated by
large agribusiness companies, some questions arise about the maintenance of attributes that
characterise this type of family agriculture management. This research aimed to assess the
sustainability of family agroecosystems in S?o Rom?o settlement in Mossor?-RN, cultivated
with melon. The study was conducted by the Framework for Evaluation of Natural Resources
Management Systems Incorporating Sustainability Indicators (MESMIS), in ten
agroecosystems of the mentioned settlement. The data were obtained from semi-structured
interviews and field observations, so that the answers, considerations and comments made by
settlers, were widely used to cycle through the six steps of the MESMIS evaluation. As a
result of the work, were determined seven critical points affecting sustainability, being: water
resources, soils, reliance on external inputs, biodiversity, quality of life, family income and
community organizing, from which was derived twenty-three indicators that sought to reflect
the actual state of sustainability of the agroecosystems
