Abstract: Sustainable Use Units have been carrying out sustainable management since the 1990s in the State of Amazonas, leading to research on the influence of management plans on restoring ecosystems. We developed an integrative review and analyzed official documents, data from the Brazilian government and information obtained from fishermen on the Unini River Extractive Reserve. The review articles were analyzed qualitatively, and a X2 test was used to verify differences in the distribution of proportions of pirarucu between the years after implementing the management. The management plan was the most cited as a solution to the environmental, social, and economic problems identified in the ecosystems. The data showed an increase in the numbers of pirarucu both in State of Amazonas and in the Unini River Reserve, reinforcing the perception of the community and fishermen. This suggests that when management plans are developed with the involvement of the local community, they present potential to restore ecosystems.

Protected areas are the most frequently used tool for the mitigation of threats to biodiversity. However, without effective management, the creation of new protected areas may be ineffective. In Brazil, protected areas must have both a governing body (consultative or deliberative council) and an official management plan. Here, we analyzed general trends and patterns in the approval of the management plans for Brazilian federal protected areas. We considered all federal protected areas, and compiled data on (i) the year the area was created, (ii) the type of protected area (integral protection vs. sustainable use), (iii) year its management plan was approved, (iv) year in which the management plan was revised after its approval, (v) total area (in hectares), and (vi) the biome in which the area is located. We stablished three groups of protected area: 1) Group A: protected areas created prior to 1979, 2) Group B: protected areas created between 1979 and 1999, and 3) Group C: protected areas created between 2000 to the present time. Finally, we tested whether time for the approval of the management plan suffered a simultaneous effect of the type of biome and type of categories of protected area (strictly protected vs. sustainable use areas). We found 211 (63.17% of the 334) protected areas with management plan. On average, the time taken for the creation and approval of a management plan far exceeds the deadlines (5 yrs.) defined under current Brazilian law. All Brazilian biomes are poorly covered by protected areas with effective management plans, with the highest and lowest value observed in the Pantanal (100%) and Caatinga (46.42%), respectively. Our results suggest that the effectiveness of many federal protected areas in Brazil can be reduced considerably by the lack of a management plan, with deleterious consequences for the country’s principal conservation strategies.

Qualitative and quantitative phytoplankton compositions of 10 Montenegrin lakes were investigated in the summer of 2007. The obtained results were compared with a previous study-period that was undertaken two decades ago. In the first period, diatoms numerically dominated the phytoplankton community in all studied lakes, while in the second period, the same was observed only in three of the ten lakes; in other studied lakes the relative contributions of green algae, dinoflagellates and/or cyanobacteria increased, while the contribution of diatoms decreased. The shift observed in phytoplankton composition and diversity in some of the studied lakes indicates an increase in the trophic level over the two decades. The sustainable management plan of the aquatic ecosystems in Montenegro should include the establishment of an environmental monitoring system in order to record any alterations that may take place in water quality.

Increasingly, the multiplicity of products, services, and values, and the diversity of interests from different resource users and groups, is being acknowledged as vital for sustainable use. This calls for a shift from protection to sustainable use and to resource-user focus. The aim of this study is to identify the spatial occurrence of livelihood values through participatory resource mapping, their changes over time and alternatives for sustainable management. A participatory resource mapping study was conducted with local community, including important stakeholders in Ekondo-Titi subregion of Cameroon. The research technique which focused on gender revealed different patterns of forest resources and changes on the landscape. The study concludes that the importance of resources varies between men and women in Ekondo-Titi subregion of Cameroon, implying that resources may have multipurpose functions, but its exact role depends on the needs of the user groups that utilize them. The divergence of opinion on certain resources is a clear indication of preferences that are gender motivated. The study also revealed that the greatest impact of land use change is the conversion of forest land into agriculture.

Mato Grosso Do Sul

The system of Conservation Units (UCs) is one of the most important public policies for the protection of biodiversity, even considering the lack of management and handling that affects some UCs in Brazil. Despite this situation, it is important to register and know the UCs (municipal, state and federal) created within the scope of the State of Mato Grosso do Sul. To this end, consultations on legislation and surveys were made through available bibliographies. The analysis of the data obtained until March 2020 indicated a total of 136 UCs, distributed among those of Sustainable Use (72.06%) and Integral Protection (27.94%), which represent 16.5% of the State’s territory. In all spheres, the largest proportion of UCs created refers to sustainable use UCs. The situation of the Conservation Units in Mato Grosso do Sul points to the urgent need for a concrete public policy, which makes it possible to meet the objectives of the different categories, in order to contribute to the conservation of nature with regard to maintenance biological diversity and diversity representative existing ecosystems in the state. Requiring for that the preparation of management plans, the consolidation of councils, the facilitation of public visitation, ecotourism, research and environmental education

The article discusses threat assessment in consecutive National Crisis Management Plans in Poland after 2010. The scope of the article is limited to the assessment of those threats that may have an impact at the state level and which are included in the National Crisis Management Plan. A general approach to threat assessment for the purposes of national crisis management plans has been taken. A reference to the accuracy of consecutive threat assessments in the context of the occurrence of real crises is included later in the article. In the final part of the article, the perspectives for threat assessment are discussed. Due attention is paid to threats which have an increased likelihood of occurring and the severest consequences.

Because of the quality of their wood and their many traditional uses, species of the Entandrophragma genus are being intensively logged, and this is likely to compromise their survival unless sustainable management is introduced. This study reviews the current status of the five main commercial Entandrophragma species: Entandrophragma angolense, E. congolense (often confused with E. angolense), E. candollei, E. cylindricum and E. utile. We suggest directions for research to improve sustainable management strategies for this genus. The study draws mainly on published scientific data, economic data (production and export statistics) and on relevant laws and regulations, but also on existing management plans and inventory reports. Although these species are reported as vulnerable on the IUCN Red List, knowledge on their management is still patchy. Industrial and artisanal logging is intensive and does not always follow a validated management plan or abide by the minimum rotation period, both of which would help to ensure the renewal of these resources. Managing them to ensure that logging is sustainable in the long term requires management measures to be developed and complied with. Sustainable use has to be based on appropriate management of natural stands and on reforestation and conservation measures. Research studies to be developed should encompass the growth rates of the species in the light of the changing climate, assessments of stocks (timber, biomass and carbon), updates of their spatial distribution, improvements to natural regeneration, reproduction processes and the anatomical and technical properties of each species. All these research topics are necessary to ensure the permanence of these Entandrophragma species.

Water governance and management are important challenges for the River Indus Basin in Pakistan. Water governance refers to social, political and economic factors that influence water management. The water scarcity and water security are a major concern for the state to control its water resources. The study aims to give Sindh water policy by exploring the challenges to Indus Basin in managing water resources and to identify opportunities Indus Basin can look to improve water management. Interviews were conducted from water experts and analysts having 5 years’ experience or more in the water sector of Pakistan through a semi-structured self-developed questionnaire using purposive sampling technique and transcripts were analyzed using thematic content analysis. The findings show that increasing population, climatic change and rising demand of water are major challenges Indus is facing and Indus with time is getting water-scarce therefore need strong institutions, civil society and legislatures to ensure equitable distribution of water and maintain the ecosystem. The study emphasizes that water governance and management are necessary for sustainable use of water. Pakistan, the water stress country needs to address ‘governance’ at a wider scale to solve problems in the Indus Basin for the livelihood of people. The research will benefit the state, water experts, institutions as well as civil society to promote efficient use of water in Indus Basin.

The silvicultural principles of a forest management plan for Canton Neuchâtel reveals itself as steeped in a systemic approach that allows us to consider the forest as a truly living system. In this context, it seems judicious to the author to conceive of the body forest personnel as a group of responsible people who share certain common ethics and who, in their work, promote the emergence of collective services recognised as beneficial to the state and which would be supported by public funding for the good of the entire community.
