Este artigo propõe um método para a estimação de Tabelas de Produção e Uso Inter-regionais em condições de informação limitada denominado Supply and Use Interregional Tables – SUIT. O SUIT é aplicado na construção de um sistema para as 27 Unidades da Federação (UF) brasileiras para o ano de 2011. As principais características do SUIT são de: (i) poder ser diretamente aplicado a sistemas compostos por diferentes hierarquias regionais, (ii) ser consistente com as matrizes de insumo-produto nacionais e (iii) ser consistente como sistema de contas regionais do IBGE. O artigo faz uma análise da estrutura produtiva, das relações interestaduais e dos fluxos de comércio entre as UFs.
Robert Solow (2015) has recently commented on Richard Goodwin's article 'The Multiplier as a Matrix' (Goodwin 1949) recalling the analogy between the Leontief-like matrix multiplier and the Kahn-Keynes multiplier. 1 By including households as one of the sectors, Goodwin's multi-sectorial approach has paved the way to replicate Kahn-Keynes by calculating an aggregate national income multiplier as a weighted average of all sector multipliers. Having Wassily Leontief as its most influential source of inspiration, the quest for relaxing the aggregative nature of the Keynesian system has nudged not only Goodwin's initial scientific accomplishments, but also other early authors' , especially Chipman (1950), who developed, at the same time as Goodwin, the notion of sector multipliers. The idea that a net increase in the rate of home investment (and other autonomous injections) propagates in the entire system generating higher-order effects is even more appealing in a multi-sectorial context. Rather than attempting to create a complete model of the economy, the main interest was to trace some of the effects of such injections in the system (Solow 2015).
Brazil is known for its abundant water supply. However, an uneven spatial distribution of water and strong concentration of economic activities has caused some regions to face water restrictions. The objective of this research is to identify the main water users in Brazil, in terms of virtual blue water, and the impacts of the water use pattern on the regional Water Exploitation Index. Among the main results, the hydrographic basin Tietê was identified as the largest responsible basin for virtual blue water demand, while the hydrographic basin Litoral AL PE PB was an important virtual water supplier. Virtual blue water flows are largely interregional and a majority of the flows (66 percent) were exports from basins where the water balance indicates potential water restrictions. These results suggest that interregional trade in virtual blue water affects water availability for some Brazilian hydrographic basins, potentially undermining water security.
Muito se fala sobre o papel das tecnologias no uso dos recursos naturais de forma eficiente e, com a implementação da Agenda 2030, o tema ganhou ainda mais relevância. Este texto visa apresentar um panorama da eficiência no uso de água pelo mundo, reunindo informações através de uma comparação internacional utilizando o indicador
“Alterações na Eficiência do Uso da Água ” do Objetivo de Desenvolvimento Sustentável (ODS) 6 (meta 6.4). Espera-se que este possa ser um primeiro passo para estudos futuros que avaliem a possibilidade de implementação de tecnologias eficientes no uso dos recursos hídricos baseadas em experiências internacionais.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
