“…It is reasonable to pursue improvements in eco-efficiency rather than the yield increases per se (Huppes and Ishikawa, 2005). Masuda (2016) employs the concept of eco-efficiency to examine agricultural production with an adequate application of nitrogen fertilisers. The eco-efficiency of the modelled farm was calculated by joining the results of linear programming and life-cycle assessment.…”

Purpose The purpose of this paper is to evaluate the implications of and assess the economic and sustainable impact of environmentally friendly technological packages introduced into agribusiness players in the centre of chilli-producing regions of Indonesia. Design/methodology/approach This study used a theory of optimisation in production as a fundamental analysis. Producers are assumed to maximise profit by allocating rational amounts of inputs as the components of technological packages. A combination of qualitative and quantitative methods was used. The rate of technology adoption was evaluated, and agribusiness performance was measured using an economic advantage and technical efficiency. Data were compiled using group discussions and individual surveys. Findings The packages of technologies improved economic and sustainability performance of agribusiness resulting from efficient use of agrochemicals and water resource, and increase the production. Socio-economic and technical factors influenced performance farmers, as agribusiness players responded positively towards the ecological technology packages. Research limitations/implications The sustainability of agribusiness was indicated by the reduction in agrochemical use and by the efficient use of water irrigation. There are other measures of sustainability, which are beyond this study. Additional studies are expected to fill the gap. Practical implications Considerable potential exists for broad adoption of these technological packages in Indonesia if they are disseminated effectively and in a close partnership with local extension agencies, farmers’ organisations, local non-governmental organisations and private sectors. Originality/value This study provides a realistic representation of a current condition because this is an empirical study conducted at the grass-root level. Sustainability of agribusiness practices was achieved with ecological technological packages.

“…Numerous environmental impact assessment studies of rice production using LCA have been conducted. Many of these studies assessed only global warming (e.g., [11,12]) or a small number of environmental impact categories such as global warming and eutrophication (e.g., [13,14]), although several studies aggregated multiple environmental impacts using a weighting approach [15][16][17][18][19]. However, as noted above, these weighting assessments were subjective and reflected value choices [5].…”

To promote sustainable agriculture worldwide, it is important to understand what constitutes eco-efficiency for rice, a staple food in many countries. This study examined whether expanding the scale of rice farming contributed to the improved eco-efficiency of intensive rice production in Japan. Both life cycle assessment (LCA) and data envelopment analysis (DEA) were used to measure comprehensively the eco-efficiency of rice production. A DEA window analysis technique with two DEA inputs (global warming and eutrophication from the LCA results) and one DEA output (weight-based rice yield) was applied to the statistical data for 2005–2011 categorized by the size of rice farms. The results indicate that expanding the size of rice farms is an effective way of improving the eco-efficiency of intensive rice production in Japan. The important factors for improving eco-efficiency are the implementation of economies of scale, reduced outsourcing of farm work, and savings in chemical fertilizers and pesticides. Expansion of the size of rice farms through the recent abolition of the rice production adjustment program will also contribute to improving the eco-efficiency of Japanese rice production.

“…In this same vein, to evaluate EE in agricultural production, Masuda [63] considered eco-efficiency in his study as agricultural revenue divided by potential global warming. In Song and Chen [64], a method combining water footprint (WF) analysis and stochastic frontier approach (SFA) was developed to estimate the eco-efficiency of grain production in China.…”

An AHP-Based Procedure for Model Selection for Eco-Efficiency Assessment

Modelling eco-efficiency is becoming a wide field of research shown by a large body of scientific literature on the subjects concerned. This paper, after performing a systematic literature review (SLR) to identify existing models for process eco-efficiency assessments, provides a methodology, based on the analytic hierarchy process (AHP) method, for choosing the eco-efficiency assessment model to be used for a given application (process, product, or service). For the SLR, papers from the databases Scopus, Web of Science and Science Direct were used. Forty articles were considered for this study, using as the main selection criterion articles that present an eco-efficiency assessment model, since the purpose was to survey the types of existing models that are used to assess processes, products or services for eco-efficiency. With the systematic review carried out, it was possible to identify the types of models that exist and how they are used in different sectors, always aiming to identify if what was analyzed is eco-efficient and what points need to be improved. The proposed AHP-based methodology was applied to a numerical model to outline how to apply the methodology. The approach was easy to use and effective in identifying the proper eco-efficiency model.
