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.

Brazil is one of the main suppliers of aquarium species globally, and Ceará state is a recognised trading centre for this activity. Despite Brazilian Postal Law forbidding the mailing of live or dead organisms, smugglers still use this service to transport aquarium species throughout the country. To assess this unlawful practice, the Brazilian Institute of the Environment and Renewable Natural Resources (IBAMA, Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis) and the Brazilian Post and Telegraph Co. (ECT, Empresa Brasileira de Correios e Telégrafos) conducted 57 confiscations involving domestic transportation only. The main origin and principal destination of the confiscated packages was south-eastern Brazil, especially São Paulo state, where package inspections must be intensified. Considering all groups of seized species, freshwater fish were by far the most represented organisms due to intense translocation of Betta splendens. Some of the confiscated marine fish, echinoderms and cnidarians are included in the Brazilian List of Threatened Species; thus, their exploitation is restricted or forbidden. In addition, only 18 of the seized species were native to Brazil, and just 12 of them occur naturally in Ceará state, which both raises concerns about potential bioinvasions and demands more control by the Brazilian authorities of smuggled species. Although some illegal traders were repeatedly caught mailing organisms, confiscations do seem to mitigate the illicit transportation of species to some extent.

The Tembe Elephant Park was proclaimed in 1983 after negotiations between the then KwaZulu Bureau of Natural Resources and the Tembe Tribal Authority in consultation with the local communities of northern Maputaland, KwaZulu-Natal, South Africa. The park boundaries were subsequently fenced and animal numbers started to increase. The fence has kept the utilisation of renewable natural resources by the local communities at bay for the past 19 years. In this period, the vegetation of the park has been utilised only by the indigenous fauna, but it has been affected by management decisions and possibly also regional environmental changes.

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.

<p>Atualmente, é possível constatar um crescente aumento da degradação do meio, o qual está relacionado ao desenvolvimento das atividades humanas. Os terrenos cársticos são ambientes muito frágeis, isso porque o sistema hidrológico cárstico é altamente vulnerável à poluição em decorrência de suas características físicas de drenagem predominantemente vertical e ausência de camadas que filtram a água antes de sua chegada aos aquíferos. Diante disso, o principal objetivo do presente trabalho consistiu em realizar, mediante adaptações necessárias, o diagnóstico físico-conservacionista do ambiente cárstico da bacia do córrego Cana-brava, inserida nos municípios de Aurora do Tocantins e Lavandeira, visando contribuir para um melhor conhecimento do carste no estado do Tocantins, além de servir como suporte à elaboração de diretrizes e estratégias de ação voltadas à preservação ambiental da área de estudo. A metodologia do diagnóstico físico-conservacionista busca diagnosticar a situação real em que se encontram os recursos naturais renováveis em um determinado espaço geográfico e fornece indicativos concretos para o manejo e uso racional de recursos naturais renováveis da bacia hidrográfica.

Indonesia is a very large and wide country, consisting of many islands and abundant natural resources. Natural resources in Indonesia are everything that comes from nature that is used to meet the needs of human life. Generally, natural resources in Indonesia can be classified based on their nature, namely renewable natural resources and non-renewable natural resources. Humans are very dependent on natural resources and the sustainability of natural resources is strongly influenced by human activities. Watershed is one of the natural resources that is very complex and consists of various components that make it up. The functions and benefits of water resources themselves, including rivers, require various efforts to improve and protect water so that it is efficient and effective for living things and the surrounding environment. One of them is the Bindu river in the Kesiman Traditional Village. The Bindu River is widely used by the community, causing water pollution in the Bindu river, such as the Kesiman Traditional Village which has an important role in suppressing the occurrence of water pollution that occurs in the Bindu river.   Negara Indonesia merupakan negara yang sangat besar dan luas, terdiri dari banyak pulau dan sumber daya alam yang melimpah. Sumber daya alam di Indonesia merupakan segala sesuatu yang berasal dari alam yang digunakan untuk memenuhi kebutuhan hidup manusia. Umumnya sumber daya alam di Indonesia dapat digolongkan berdasarkan sifatnya yaitu sumber daya alam yang dapat diperbaharui dan sumber daya alam yang tidak dapat diperbaharui. Manusia sangat bergantung pada sumber daya alam dan kelestarian sumber daya alam sangat dipengaruhi oleh aktivitas manusia. Daerah aliran sungai merupakan salah satu sumber daya alam yang sangat kompleks dan terdiri dari berbagai komponen yang menyusunnya. Fungsi dan manfaat sumber daya air sendiri termasuk sungai memerlukan berbagai upaya untuk peningkatan dan perlindungan air agar berdaya guna dan berhasil guna bagi makhluk hidup dan lingkungan sekitar. Salah satunya adalah sungai Bindu yang berada di Desa Adat Kesiman. Sungai Bindu banyak dimanfaatkan oleh masyarakat sehingga menyebabkan terjadinya pencemaran air di sungai Bindu, seperti Desa Adat Kesiman memiliki peranan penting dalam menekan terjadinya pencemaran air yang terjadi di sungai Bindu.
