Abstract Natural resource-based economies have long relied on foreign demand to fuel their growth. For instance, the extractive sectors in Peru have experienced a rapid expansion, driven by a rising demand for commodities. Alongside economic growth, extractive operations have triggered social and environmental concerns among the various stakeholders, thus resulting in either social conflict or a deterioration of the relationship between companies in the extractive industries and local communities. In this context, the purpose of this paper is to understand the relationships between companies in the extractive industries and rural families. This research uses the case-study method. The findings show that a trustful relationship is supported by a beneficiary-society approach that builds upon philanthropic and ethical types of relationships. Unlike the type of relationship based on economic or legal interests, a trust-based relationship offers avenues for managing social conflict that have yet to be explored.

Banana, mamão e abacaxi são as frutas tropicais mais consumidas no mundo, sendo o Brasil um dos principais produtores. Os fungos Colletotrichum musae, Colletotrichum gloeosporioides e Fusarium subglutinans f.sp ananas são os principais causadores de doenças e perdas em pós-colheita de frutas. A proposta deste estudo foi avaliar a eficácia de cinco monoterpenos em inibir o crescimento micelial e a germinação dos conídios destes três fitopatógenos. Os monoterpenos citral, citronelal, L-carvona, isopulegol e a-pineno foram diluídos em etanol à concentração final de 0,2 a 1%. Todos os monoterpenos testados inibiram os três fungos estudados de maneira dose-dependente. Citral foi o mais efetivo dos óleos testados e apresentou uma potente atividade fungicida em concentrações acima de 0,5%. Mais ainda, avaliação in vivo com estas frutas tropicais demonstrou a eficácia de citral como inibidor do crescimento fúngico. Estes resultados indicam o uso em potencial de citral como um pesticida natural no controle das doenças em pós-colheita de frutas tropicais.

Banana, papaya and pineapple are the most consumed tropical fruits in the world, being Brazil one of the main producers. Fungi Colletotrichum musae, Colletotrichum gloeosporioides and Fusarium subglutinans f.sp. ananas cause severe post harvest diseases and losses in fruits quality. The aim of this work was to evaluate the effectiveness of five monoterpenes to inhibit the mycelial growth and conidia germination of these three phytopathogens. The monoterpenes citral, citronellal, L-carvone, isopullegol and a-pinene were diluted in ethanol to final concentrations from 0.2 to 1%. All monoterpenes were found to inhibit the growth of the three studies fungi in a dose-dependent manner. Citral was the most effective of the oils tested and showed potent fungicidal activity at concentrations above 0.5%. Also, in vivo evaluation with these tropical fruits demonstrated the efficiency of citral to inhibit fungal growth. These results indicate the potential use of citral as a natural pesticide control of post-harvest fruit diseases.
