The depletion of non-renewable natural resources (primarily mineral and energy resources) and its assessment is a problem that is analyzed based on the concept of sustainable development. Mineral resource depletion assessment is particularly important for resource-based economies. It provides for assessing the impact of mineral asset disposal that results from the suspension or termination of operations conducted by a mining company due to insurmountable circumstances. The results of such an event will be manifested at the national, regional, and local levels and felt by mining companies, suppliers, workers, the population of the territory, and other stakeholders. The study clarifies the attributes and essence of mineral resource depletion, analyzes the advantages and limitations of the existing tools for assessing mineral resource depletion, identifies depletion factors, describes a methodology for assessing mineral resource depletion, and contains a case study of a tin deposit. The results of the study contribute to the development of the theory on the depletion of non-renewable natural resources. They provide for assessing losses to social wellbeing that can be caused by stopping the use of profitable mineral reserves.

As frações granulométricas do solo são consideradas recursos naturais não renováveis, devido a escala de tempo necessária para sua formação. A argila possui elevada disponibilidade na natureza, e por isso seu uso ainda é indiscriminado. É a matéria-prima principal para as indústrias de cerâmica vermelha pulverizadas em todo o território brasileiro. O objetivo do trabalho foi realizar uma discussão acerca do recurso natural não renovável argila e seu uso no processo produtivo da Indústria de cerâmica vermelha. Este foi desenvolvido através de pesquisa bibliográfica, e estudo de caso com realização de visitas técnicas a uma indústria de cerâmica vermelha localizada no município de Paudalho no estado de Pernambuco. No ano de 2013 a Indústria X adquiriu para estoque e consumo 70.161 toneladas, para uma produção de 35.806.268 blocos de cerâmica. De todo o quantitativo produzido houve uma perda de 7,5%, que reflete em 4.768 toneladas de argila e num prejuízo aproximado de R$ 845.835,52. Através do trabalho realizado percebe-se que há uma necessidade de planejamento da exploração e uso dos recursos naturais não renováveis, pois estes podem se tornar escassos e inviabilizar determinados processos produtivos. Isso pode acarretar em conflitos sociais e econômicos, pela valoração dos recursos e diminuição de disponibilidade para uso, ocasionando redução dos lucros por parte dos empresários e por consequência diminuição na oferta de empregos.Use of clay in the production process of the Red Ceramics: A case study in the city of Paudalho, Pernambuco Abstract: The fractions of soil are considered non-renewable natural resources, because the time scale required for its formation. Clay has high availability in nature, and therefore its use is still indiscriminate. It is the main raw material for the manufacture of red ceramic sprayed throughout the Brazilian territory. The objective was to conduct a discussion of non-renewable natural resource clay and its use in industry's production process of red ceramic. It was developed through literature review and case study of technical a red ceramic industry in the municipality of Paudalho in Pernambuco state visits. In 2013 the X Industry acquired for stock and consumption 70,161 tons, for a production of 35,806,268 ceramic blocks. The entire quantity produced there was a loss of 7.5%, which reflects in 4,768 tons of clay and an approximate loss of R $ 845,835.52. Through work is noticed that there is a need for planning of exploration and use of non-renewable natural resources, as they may become scarce and derail certain production processes. This can lead to social and economic conflicts, the valuation of resources and reduced availability for use, resulting in lower profits for entrepreneurs and consequently decrease in the supply of jobs.

The article presents an analysis of alternative theories of ecological and economic development. The authors formulate the role of the environmental factor in socio-economic development, taking into account the ideas of alternative economic schools and trends. The paper analyzes the problems of preserving the environment as the basis of human life. This takes into account the nature of the impact of anthropogenic pressure on natural complexes and objects, due to increased consumption, excessive withdrawal of renewable natural resources that exceed the rate of natural recovery, a reduction in the reserves of non-renewable natural resources, as well as an increase in the population. At the same time, the article focuses on the problems of sustainable, balanced, harmonious development of production and social systems.

Nowadays the heightened awareness of the critical trend in resource depletion impels to improve the eco − sustainability of any productive process. The research presented in this paper aims to quantify the environmental impact of the emerging productive process of edible flowers, focusing on two model species, i.e., Begonia x semperflorens − cultorum hort and Viola cornuta L., and two types of product, i.e., flowering potted plants sold in plastic vases and packaged flowers ready to be consumed. The study was carried out in an Italian nursery located in Tuscany, interviewing the owners in order to complete the Life Cycle Inventory, assessing the value of the impact categories, and using the “cradle to gate” approach. The information about the production of flowering potted plants and packaged flowers were inserted in a database and elaborated by the appropriate software. The results of the Life Cycle Assessment (LCA) analysis referred to 1 g of fresh edible flowers and were expressed in four impact categories. Global Warming Potential (GWP) values ranged from 24.94 to 31.25 g CO2 eq/g flowers, Acidification Potential (AP) ranged from 8.169E − 02 to 1.249E − 01 g SO2 eq/g flowers, Eutrophication Potential (EP) ranged from 3.961E − 02 to 5.284E − 02 g PO43 − eq/g flowers, and Photochemical Ozone Creation Potential (POCP) ranged from 8.998E − 03 to 1.134E − 02 g C2H4 eq/g flowers. Begonias showed lower emissions than violas in the GWP and POCP indexes, whereas violas showed lower values in the AP and EP impact categories. The most impactful phase was the propagation, accounting on average for 42% of the total emissions. Overall, the findings highlighted a higher environmental load for the production of both begonias and violas packaged flowers, especially if in small containers, rather than as potted plants, with an emission percentage increase from 8% to 17% among the impact categories.

The capacity to detect, control and manage emerging and re-emerging zoonotic diseases in Africa has been limited by a lack of utilisation of available reporting structures and policies to support programmes at national and local levels. This study explored the impact of the Zambian government policies on animal and human disease reporting and management and on One Health opportunities. An in-depth review and analysis of strengths, weaknesses, opportunities, and threats in the existing policies and reporting structures in the departments responsible for Veterinary Services, Health, and Wildlife, was conducted. According to our findings, sub-optimal implementation of existing policies related to the control of zoonotic diseases was impacting disease reporting, and reporting structures play an important role in effective and sustainable reporting of zoonotic diseases. Further, the study explored capacities and strategies in trypanosomiasis control as a case study that could prompt effective adoption of a One Health approach, and as such, the study suggests measures that could help to assess the performance of a One Health system in the control of African trypanosomiasis and other zoonotic diseases.
