Plano de negócio de uma unidade de transformação de frutos em São Tomé e Príncipe

Entre as culturas da Ilha de São Tomé com maior destaque a nível de produção e consumo, podemos apontar a banana e a fruta-pão. A par com os cacaueiros, estas duas fruteiras são as que se encontram mais presentes nos sistemas agroflorestais. Ao longo dos anos tem-se verificado o subaproveitamento das produções frutícolas bem como das produções espontâneas e sazonais O presente trabalho tem como objetivo a elaboração de um plano de negócio para uma unidade de transformação de frutos em São Tomé e Príncipe, com o intuito de promover a segurança alimentar no país através da melhoria da qualidade dos produtos disponibilizados às populações e a valorização de produtos agrícolas, evitando o subaproveitamento dos excedentes das produções frutícolas. Atualmente, tendo em conta as estimativas de aumento de produção da banana, crê-se que a importância desta fruta para o rendimento familiar tenha aumentado, para além de constituir uma fonte de rendimento mais regular ao longo do ano, por comparação com o cacau e outras cultivares; Business Plan for a Fruit Processing Plant in São Tomé and Príncipe Abstract: Among the cultures of the island of São Tomé with greater prominence in terms of production and consumption, we can point out the banana and the breadfruit. Along with cacao trees, these two fruit are the ones that are the most present in agroforestry systems. Over the years, there has been an underuse of fruit production and, as well as spontaneous and seasonal production. The present work aims the elaboration of a business plan for a fruit processing plant in São Tomé and Príncipe. The idea is promoting food security in the country by improving the quality of the products available to the population and the valorization of agricultural products, avoiding the waste of fruit production. Currently, and taking into account the estimates the increased production of banana, one believes that the importance of this fruit for family income has increased, and it is a more regular source of income throughout the year, compared to cocoa and other cultivars

Towards sustainable development through the perspective of eco-efficiency - A systematic literature review

© 2017 Elsevier Ltd. Sustainability concerns have increasingly gained importance among organizations and their stakeholders around the world. In this context, eco-efficiency has become a consistent tool towards the transition to sustainable development and the efforts of eco-efficiency indicators have been used for comparative studies and decision-making tasks, providing better financial, environmental, and social performance. The aim of this paper is to provide a systematic literature review on the theme of sustainable development from the perspective of eco-efficiency, with the adaptation of the Knowledge Development Process intervention instrument - constructivist (ProKnow-C). The paper identifies and structures the state-of-the-art between Eco-Efficiency and Sustainable Development with a view to: (i) selecting a Bibliographic Portfolio (BP) that is aligned with the perception of the researchers on the theme; (ii) performing a bibliometric analysis of the selected BP; (iii) performing a thematic synthesis; (iv) finding the integration of eco-efficiency and sustainable development with other approaches; (v) proposing an innovative framework to achieve sustainable development through eco-efficiency indicators; and (vi) finding paths for further research. This research makes multiple new contributions, providing both academics and practitioners a better panorama to achieve sustainable development through eco-efficiency by expanding the literature review, highlighting the synergies and barriers between eco-efficiency and sustainable development and by comparing and analysing them, showing its relevant features. In addition, we synthesized the contributions of the BP according to the BASF indicators, sustainable dimensions and four measurement levels: industry, organization, project and process to better describe the current academic scenario on the subject

QUALIDADE E CONSERVAÇÃO DA ALFACE CULTIVADA COM REJEITO DA DESSALINIZAÇÃO

The objective of this work was to evaluate the effect of desalination wastewater on the post harvest quality and conservation of lettuce, cultivars Verônica and Quatro Estações, produced in hydroponic system with coconut fiber. The test was developed in an protected environment from the Department of Environmental Sciences of Universidade Federal Rural do Semi-Árido, located in Mossoró/RN, installed in an experimental design of randomized blocks, in factorial scheme 2 x 2 x 5, with three replicates, the treatments consisted of two lettuce cultivars (Verônica and Quatro Estações), two times of evaluation (at the time of harvest and after three days of conservation) and five levels of salinity of the nutrient solution with or without a further dilution of the tailing desalination of brackish water (1.1; 2.4; 3.6; 4.7 and 5.7 dS m-1). Quatro Estações cultivar showed lower weight loss during the conservation period and higher total value of chlorophyll and pH. The matter of vitamin C and soluble solids were influenced by the reuse of tailing from desalination in nutrient solution, presenting higher level in the highest salt content studied. The cultivated lettuce on coconut fiber irrigated with reuse of the tailing nutrient solution in desalination presented, in general, good appearance both at harvest and after three days of conservation

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
