Studies demonstrate that Information and Communication Technologies (ICTs) can assist in the emancipation of users, offering them the possibility of accessing information and knowledge in order to become agents of their own history. In this sense, the objective of this investigation is to analyze the use of ICTs by farming families in the southern region of Brazil, pointing out the limits and possibilities in the context of family farming. To achieve this goal, forms were applied to thirty family units in the municipalities of Xaxim / SC and Pato Branco / PR. The research found that the possibility of accessing and using ICTs represents a need for family farmers in view of the competitiveness of the current market. Despite the importance and significance that ICTs represent to rural areas, the field of study reveals that the conditions of this access have limitations, as the technical system is deficient, which prevents effective access to all the potential that these technologies hold. In some cases, even with a high investment, the farmer cannot access a better service or even use it properly. Finally, it appears that ICTs are inserted in the context of family farming and represent the possibility of network integration and shared construction of knowledge. [ABSTRACT FROM AUTHOR]

When considering the general parameters that supports the sustainability of agroecosystems, it is noticed that there are many dimensions that need attention in their regarding its emerging maintenance, mainly economic, social and environmental dimensions. Approaching the current reality of family farmers, we see that their social sustainability is fragile and for this, we must seek new methodologies and strategies, that carry out a more detailed survey of the main critical points and also the from these to seek those indicators that can serve as forces and opportunities, solving the threats and weaknesses of the sustainability of agroecosystems. Face of it, this researching had as principal objective evaluate the sustainability of carnies agroecossistems from Pato Branco - PR municipality over the time. For that, three methodologies were used, the main one being the MESMIS methodology that uses sustainability indicators to perform the evaluation over time in agroecosystems supported by the network analysis and the SWOT matrix. A total of 112 indicators were analyzed within the social, environmental and economic dimensions, after the analysis it was verified that agroecosystems have good levels of economic sustainability, however, some points within social and environmental sustainability are still fragile. And in order for these to be strengthened, a network must be established involving all farmers, together with the local institutions, helping to solve the critical points, and for this, the importance of creating associations that of the common good and help in the sustainability of these agroecosystems.
