One of the most interesting opportunities when introducing e-commerce in producer consumer networks is that the new information technology structure may be used to empower consumers to be more active participants in the economic value creation process (e.g., Hoffman and Novak, 1996; Alba et al., 1997). Consumers may for example create their own personalized version of a Web site or services, or communicate with other consumers about products they have bought. Many Internet-based firms have recognized the potential benefits of these opportunities and are encouraging consumers to make contributions to their Web sites. Some examples of Web sites encouraging various types of consumer contributions are presented in Table 1. Allowing consumers to contribute more actively to different stages of the supply chain can create three main types of economic benefits. First, consumers can assist producers in achieving lower production costs and creating higher consumption utility for the consumer’s own benefit (e.g., by lowering transaction costs or by allowing producers to make more customized products). Secondly, they can also assist producers in generating similar benefits for other consumers. Thirdly, the Internet can be a vehicle through which consumers can generate additional value for each other, directly and without business intermediation (e.g., by providing suggestions for new product designs or by sharing information about past consumption experiences).

Necrotic enteritis (NE) caused by Clostridium perfringens (C. perfringens) results in impaired bird growth performance and increased production costs. Nanotechnology application in the poultry industry to control NE outbreaks is still not completely clarified. Therefore, the efficacy of dietary garlic nano-hydrogel (G-NHG) on broilers growth performance, intestinal integrity, economic returns and its potency to alleviate C. perfringens levels using NE challenge model were addressed. A total of 1200 male broiler chicks (Ross 308) were assigned into six groups; four supplemented with 100, 200, 300 or 400 mg of G-NHG/kg diet and co-challenged with C. perfringens at 21, 22 and 23 d of age and two control groups fed basal diet with or without C. perfringens challenge. Over the total growing period, the 400 mg/kg G-NHG group had the most improved body weight gain and feed conversion efficiency regardless of challenge. Parallel with these results, the mRNA expression of genes encoding digestive enzymes (alpha 2A amylase (AMY2A), pancreatic lipase (PNLIP) and cholecystokinin (CCK)) and intestinal barriers (junctional adhesion molecule-2 (JAM-2), occludin and mucin-2 (Muc-2)) were increased in groups fed G-NHG at higher levels to be nearly similar to those in the unchallenged group. At 14 d post challenge, real-time PCR results revealed that inclusion of G-NHG led to a dose-dependently decrease in the C. perfringens population, thereby decreasing the birds’ intestinal lesion score and mortality rates. Using 400 mg/kg of G-NHG remarkably ameliorated the adverse effects of NE caused by C. perfringens challenge, which contributed to better growth performance of challenged birds with rational economic benefits.

Biomass has a large share in the energy generation matrix, due to the regional economic benefits. This work has as main objective to evaluate the parameters used in the manufacture of briquettes produced with forest residues and the economic engineering for the manufacturer. The forest residues were: wood chips and chips of Eucalyptus spp. and barks of Pinus taeda. The evaluations were the chemical characterization of forest residues and the costs involved in the briquetting process. The forest residues presented extractive chemical composition and lignin. The production costs of the briquettes were affected mainly by the equipment, being the Pinus taeda barks the one that presented higher production cost. However, the production costs obtained in this study are approximately 20% lower than the production costs using traditional methods for forest firewood. The energy value from biomass allows the reduction of the dependence of energy, which can be used for the generation of steam or electricity, for subsistence. A fact for energy conversion is to evaluate the material moisture. It is suitable to burn residues with moisture between 45 to 55%. The consumed electric energy is important to evaluate the total costs. The energy required depends on the quality of raw material and the system employed. Forest residues is an important source for eco firewood production, contributing to energy generation and decreasing of the solid waste stored at the company. In this way, the new parameters for briquetting biomass forest wastes shown in this work, which is an important stage of the process, make economically viable and environmentally suitable the eco firewood production.

Agriculture has an important role in food security in Indonesia from micro to macro level. One of the agricultural subsectors is horticulture particularly in potato that can support food diversification programs in Indonesia. The problem that occurs in horticultural commodities is the fluctuating selling prices that affect the economic benefits received by business actors. This study aims to analyze the revenue of potato farmers from 2016 to 2018. The research was conducted in Pangalengan Sub District by including 52 potato farmers. The data in this study used both primary and secondary data, which were then analyzed quantitatively. The results of the study showed that the average amount of potato production in 2016 to 2018 in Pangalengan Sub District was 17.27 tons per hectare, while the average price of potatos in the last three years was Rp. 7,640 per kg. Based on the results of the study, the average of potato revenues in 2016 - 2018 is Rp. 131.946.193 per hectare. Revenue of potato farmers in Pangalengan Sub District is quite large, thus potato farmers have the potential to earn large profits if they can reduce production costs.

Abstract BackgroundNatural dyes used since historic times for coloring food, leather, textile fibers, and paint body parts. The use of natural dyes has suffered drastically under the influence of modern technologies in the textile industry and socio-economic changes. Hence, ethnobotanical studies of indigenous dye plants and dyeing craft in local communities are urged to protect their potential ecological and economic value. MethodsWe conducted semi-structured surveys on dye plants and traditional craft in 11 Monpa villages of Mêdog County, South-east Tibet, China. The cultural significance of local dye plants was evaluated by an index of cultural importance (CI). Field research was conducted to record the indigenous madder (the root of Rubia wallichiana Decne.) dyeing craft. An experiment was performed with aqueous extract and ethyl alcohol extract of residue remained after water extraction. These two dye solutions were respectively used to dye two fabrics with two biomordants and two metallic mordants by three mordanting methods. We evaluated color properties that were characterized by physicochemical evaluations using UV-visible spectroscopy and FTIR analysis. The dyed fabrics were evaluated by indicators of color strength and fastness including washing, rubbing, and perspiration. ResultsAltogether 15 species belong to 12 families were listed as dye plants, which were used in cloth and food dyeing. The CI of R. wallichiana was highest. Monpa ethnic group used madder directly or with metallic mordants. It was found experimentally that biomordants and metallic mordants were comparable in improving the dyeing properties of indigenous madder. The dyeing properties of both extracts of madder were equal or ethyl alcohol extraction was marginally better.ConclusionsUse of dye plants and indigenous knowledge of dyeing still present in the Monpa ethnic group. Our experiment revealed the feasibility of enhancing the dyeing property and reuse of the residue from madder dyeing. The improved dyeing and reuse of residue can improve the ecological and economic benefits of local meanwhile provide basic application research for the subsequent commercialization of plant dyes.

Peru has a 10-year ban on genetically modified (GM) crops and food that was approved by the Peruvian congress in 2011. Is it scientifically justified or is it a cause and effect fallacy that will make Peru fall behind in taking advantage of this technology and its potential benefits to everyone else in the economy? In order to answer this question, a literature review was carried out to examine the three most commonly used arguments against genetically modified organisms (GMOs) by farmers and all those related to the agriculture industry, reaching the conclusion that they are not one hundred percent plausible. Further research showed the multiple, potential economic benefits that GM seeds could bring about to Peru, which are related to increased labor productivity, the development of human capital, and the expansion of renewable energy sources and its implications for trade and employment – the environmental and health benefits of GMO varieties are also discussed. This paper elaborates on such matters by applying different macro and microeconomic concepts, i.e., market structures and competition, the theory of the firm, and scarcity, among others; and provides insights about the different socio-economic realities present in Peru and possible ways to improve them.

The EU Biodiversity Strategy to 2020 determines that “Member States, with the assistance of the Commission, will map and assess the state of ecosystems and their services in their national territory by 2014, assess the economic value of such services, and promote the integration of these values into accounting and reporting systems at EU and national level by 2020”. Mapping and assessment of ecosystem services provides several benefits, one of which is baseline data providing to measure net future gains or losses and data integration into spatial development process. The aim of the paper is to present and discuss the approach taken to assessing ecosystem services in order to introduce necessity of mapping and assessment of ecosystems and their services for planning and decision-making process in Latvia. The paper will focus on terminology interpretation of ecosystem services, introducing with set of developed indicators for assessment of ecosystem services and define appropriate for Latvia. The paper closes with estimation of potential benefits and necessity to integrate assessment of ecosystems services in spatial planning and decision-making process.

Demonstrating economic benefits generated by protected areas is often pointed out as pivotal for supporting decision-making. We argue in this paper that the concept of ecosystem services (ES), defined as the benefits humans derive from ecosystems, provides a consistent framework to approach this issue as it links ecosystem functioning and benefits, including benefits with economic value. This study aimed at providing evidence on how to bring the economic value of protected areas to the decision-making process and contributing to extend current EU Member States' experience in mapping and assessing the economic value of ES in the context of the EU Biodiversity Strategy to 2020 (Action 5). In doing so, we used the Natural Park of Serra de S. Mamede (PNSSM), located in the Alentejo NUTS II region, as a case study. We followed a three-step approach to pursue our goals, entailing stakeholders' engagement for selecting relevant ES (through a participatory workshop), biophysical mapping of ES flows (based on a multi-tiered approach depending on data availability) and spatial economic estimation of such flows (using value transfer, willingness-to-pay and market price methods). Our results indicate that the ES with highest economic value are not always the ones with higher perceived value by stakeholders. For most ES, the economic value increased with increasing protection level within the park, except for the crop production service. Although no formal uncertainty or sensitivity analysis has been performed, the following range is based on a critical assessment of non-primary data used. We estimated the aggregate annual value of PNSSM to be 11 to 33M€/year (representing 0.1 to 0.3% of the regional NUTSII Alentejo Gross Domestic Product). Our findings reinforce the need to adopt mixes of monetary and non-monetary valuation processes and not to rely just on one approach or measure of value while bringing ES into protected areas management.
