This study documents the socioeconomic impact of an innovation based on the marketing of live aquaculture products in rural communities as the Live Tilapia Points of Sales (LTPOS). A case study research conducted where the participatory strategy of "Simultaneous Production Growth Groups" (SPGG) was applied for technology innovation, which includes technology modules, organizational strategy and operational management. The results were evaluated socially and economically. In 14 months, 3531.50 kg of live tilapia were distributed in four local places for sale and self-consumption. The system obtained a BCR of 1.23 and offered as well to the rural population an alternative of fish consumption in better freshness conditions than the regular fish supply. It brings up an extra income to the main market chain participants and development of aquaculture capabilities. Therefore, the LTPOS is a viable option for diversifying livelihoods and improving regional rural population income.
Abstract:In some urban areas in Mexico, the use of firewood and charcoal as fuel for meat grills in commercial establishments, has proliferated due to economic and cultural factors. Although this activity satisfies diverse human necessities, it also generates waste that impacts the environment to local and global scales. Such is the case of CO 2 emissions produced by biomass burning in grills, whose sources are not recognized in municipal inventories of greenhouse effect gases (GEG) of the State of Veracruz. A theoretical estimation was made based in a census of establishments and an emission parameter, in order to establish a baseline on the amount of gas emitted to the atmosphere by commercial grills in Boca Del Río, Ver. It was concluded that 30 operating grills emit 134.56 tons of CO 2 into the atmosphere, equivalent to the annual combustion of 59,016.43 L of gasoline. Hence, these grills must be considered as micro-fixed sources of GEG, which influence local marine acidification and global climate change. It is recommended that it should be included in municipal, state, and national inventories for subsequent professionalization and regulation.
In the state of Veracruz, Mexico, the performance of the Tilapia (Oreochromis spp.) production system in the domestic market has been declining. Recent production results are lower than those presented in 1999, revealing that the production model adopted and used since 2001 is ineffective as a development strategy. The reason for the failure is that the model considers the technological production process as the central element of aquacultural competitiveness, without considering that production practices, marketing and consumption of goods are performed by individuals who decide and control their actions and are motivated by the values shared with their social group. This interpretation reveals the need for a new complementary conceptual framework, considering the system of production and consumption as a social self-referencing system. Thus, in this article, a model of an agricultural food-chain with a sociopoietic territorial focus on the development of the aquaculture subsector is outlined. The model is based on constructs having the following theoretical dichotomies: territorial agrifood, neo-institutional business, sociopoiesis and individual motivation.
Objective: This article describes and analyzes the main concepts of coastal ecosystems, these as a result of research concerning land-use change assessments in coastal areas. Design/Methodology/Approach: Scientific articles were searched using keywords in English and Spanish. Articles regarding land-use change assessment in coastal areas were selected, discarding those that although being on coastal zones and geographic and soil identification did not use Geographic Information System (GIS). Results: A GIS is a computer-based tool for evaluating the land-use change in coastal areas by quantifying variations. It is analyzed through GIS and its contributions; highlighting its importance and constant monitoring. Limitations of the study/Implications: This research analyzes national and international scientific information, published from 2007 to 2019, regarding the land-use change in coastal areas quantified with the digital GIS tool. Findings/Conclusions: GIS are useful tools in the identification and quantitative evaluation of changes in land-use in coastal ecosystems; which require constant evaluation due to their high dynamism.
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.
