Conservation Management Plans

Planning for management actions that address threats to biodiversity is important for securing its long term persistence. However, systematic conservation planning (SCP) has traditionally overlooked this aspect and just focused on identiying priority areas without any recommendation on actions needed. This paper develops a mixed integer mathematical programming (MIP) approach for the multi-action management planning problem (MAMP), where the goal is to find an optimal combination of management actions that abate threats, in an efficent way while accounting for connectiivty. An extended version of the MAMP model (MAMP-E) is also proposed that adds an expression for minimizing fragmentation between different actions. To evaluate the efficiency of the two models, they were applied to a case study corresponding to a large area of the Mitchell River in Northern Asutralia, where 45 species of freshwater fish are exposed to the presence of four threats. The evaluation compares our exact MIP approach with the conservation planning software Marxan and the heuristic approach developed in . The results obtained show that our MIP models have three advantages over their heuristic counterparts: shorter execution times, higher solutions quality, and a solution quality guarantee. Hence, the proposed MIP methodology provides a more effective framework for addressing the multi-action conservation problem.

Conservation management plans have a pivotal role in the preservation and sustainable management of natural and historic resources. These plans serve as detailed frameworks for implementing conservation management strategies and objectives. Recognizing the paramount importance of Conservation Management Plans (CMPs) in safeguarding cultural heritage, this study examines heritage conservation management plans set out in heritage conservation legislation in several countries around the world.
Using a descriptive analytical approach and dissecting the legal frameworks, operational tactics, and resulting impacts, the researcher examined conservation management plans within heritage conservation laws in South Africa, New Zealand, and Egypt.
Given the abundance of cultural heritage in Egypt and the need to preserve it, this research evaluates the effectiveness and shortcomings of current management plans outlined in relevant legislation. Drawing on global models, the study formulates tailored recommendations aimed at strengthening heritage conservation management plans in Egypt.
These recommendations include legislative reviews, strengthening institutional capacities, enhancing community participation, and enhancing international cooperation. By addressing pivotal challenges and benefiting from exemplary practices observed in diverse legal contexts.

Conservation' is best understood as an attitude of mind, namely a concern for value in the physical world. It is less easy to give 'value' a simple definition because the numerous interests that see value in landscape raise the question of 'value to whom'? Public parks were created with the expectation that they would provide spiritually-uplifting picturesque scenes reminiscent of then-current understanding of nature, and of art's rôle within it, and fresh air for healthy physical recreation. In the wider landscape the values still given most attention by the countryside agencies are aesthetics and nature conservation, though the ancient fabric (a term that here includes hard and soft materials) of the countryside and its patterns are a recent interest.

The changing conceptions of conservation and restoration are charted over the last century. The philosophical and practical background to one formative period-the 1980s-is explained and then contrasted to the approach of the 2010s. Differences in defining the aim of restoration, the formulation of official advice, acceptance of change, and attitudes to new work are seen as a consequence. Whilst the advances in terminology and technique remain, the concerns of today relate as much to the process, viz. in the definition of objectives, criteria for good practice and proper documentation.

It has been developed by urbanlab and commissioned by the Writers’ Union of Armenia within the scope of the Sevan Writers' Resort Conservation Management Plan Development and Scientific Restoration Project.

The National Fisheries Resources Research Institute (NaFIRRI), the Directorate of Fisheries Resources (DiFR), the Local Government fisheries staff and those from the Beach Management Units (BMUs) of the riparian districts to Lake Victoria regularly and jointly conduct Frame and Catch Assessment Surveys. The information obtained is used to guide fisheries management and development. We reveal the trends in the commercial fish catch landings and fishing effort on the Uganda side of Lake Victoria, over a 15 year period (2000-2015) and provide the underlying factors to the observed changes. The contribution of the high value large size species (Nile perch and Tilapia) to the commercial catch of Lake Victoria has significantly reduced while that of the low value small size species, Mukene has increased over a ten year (2005-2015)period. The information is intended to update and sensitize the key stakeholders on the status of the Lake Victoria fisheries. In addition, the information provi...

Man wants to see nature and evolution as separate from human activities There is the natural world, and there is man But man also belongs to the natural world If he is a ferocious predator, that too is part of evolution If cod and haddock and other species cannot survive because man kills them, something more adaptable will take their place Nature, the ultimate pragmatist, doggedly searches for something that works But as the cockroach demonstrates, what works best in nature does not always appeal to us " Mark Kurlansky, in Cod: a biography of a fish that changed the world.

The sustainable development and, also, the regional development are the last development concepts of the final years of the II-nd millenium. Despite the differences between the time apparition of the two concepts, it is obvious that, the humanity future depends of the development-sustainable and regional-and, moreover, of its implementation speed. This is, in our opinion, the most important action to be done by the actual generations. In implementing the sustainable development principles at regional levels, it is necesary to change the actual politicies design, at local and national levels. Fortunately, the similarities between the basic characteristics of the two concepts make possible this new attempt.

In 2017, Uganda’s small-scale inland fisheries underwent a significant transformation, shifting from local co-management to state military enforcement owing to ineffective enforcement of regulations and declining exports. Employing a mixed-methods approach and blending qualitative and quantitative data, we assessed the impact of military intervention on Lake Victoria’s Nile perch fishery, focusing on fishing effort, catch, and exports. Our findings indicate that military operations adhered to regulations, gaining primary support from key stakeholders, specifically motorized fishing operators. Consequently, between 2016 and 2020, legal fishing activities experienced substantial growth. By 2021, approximately 90% of Nile perch catches were made by motorized vessels using longlines and gillnets, despite a declining trend in catch-per-unit effort. Between 2015 and 2021, the Nile perch fishery saw changes: boat seines made up about 5% of motorized fleet catches in 2021, while catches in ...

The field research has been carried out in the first decade of July 2016. The research of flora, of the urban ecosystem in Orhei town is based on the studies of the 8 resorts. It highlights the presence of 106 species of magnoliophyte plants, grouped in 94 genres from 35 families. The majority of these species is represented by spontaneous ones. In some of the investigated sectors some species of cultivated trees have been identified: the walnut tree, cherry tree, apricot tree, pear tree. Species encountered with a higher frequency are ubiquitous, some of them are assigned into the category of invasive and are represented by:

RESUMEN-este estudio busca analizar las formas de producción socio-espacial de dos humedales en el departamento del Valle del Cauca entre mediados del siglo XX y principios del siglo XXi. tales formas de producción socio-espacial expresan la dialéctica entre los agentes sociales capitalistas-promotores del agro-negocio de la caña de azúcar-y las comunidades locales que resisten la presión ejercida sobre ellas, tanto por estos agentes como por el estado y sus políticas neoliberales. Para ello, se partió de la teoría de la producción social del espacio de Henri Lefebvre para interpretar la forma particular en que el capitalismo produce el espacio. La investigación integra métodos cualitativos y cuantitativos para comprender la manera en que se ha producido el espacio a lo largo de 50 años en torno a los humedales estudiados. Los resultados se convierten en conocimiento útil y práctico para las comunidades locales, lo cual les permitirá hacer frente a desafíos relacionados con la gestión ambiental, los procesos de resistencia y la conservación de humedales en el departamento del Valle del Cauca. Palabras claves: espacio; producción social del espacio; humedales. ABSTRACT-a socio-spatial analysis of the Guarinó and Guinea wetlands (municipality Jamundí-Colombia). This study seeks to analyze the socio-spatial production forms of two wetlands in the department of Valle del Cauca between the mid-twentieth and early-twenty first century. such social-spatial production forms portray the dialectic between the capitalist social agents-promoters of the sugar cane agro-business-and local communities that resist the pressure exerted both by these agents and by the state and its neoliberal policies. to this end, Henri Lefebvre's theory of social production of space is used to interpret the particular way in which capitalism produced space.

Ecotroph is a simple model that structure ecosystems as systems of energy flow surging from low to high trophic levels. Lake Victoria is the second-largest freshwater lake in the world. It is a producer of 1% of global capture fisheries and 8% producer of global inland fishery. The lake has faced overfishing and overexploitation. A pre-existing Ecopath with Ecosim model of Lake Victoria 2016, was used for data extraction, simulations, and analysis. Model outputs were juxtaposed against current biological data to determine the validity of the trends using Pearson’s correlation and modelling efficiency. Fishing did not appear to have tremendous effect on the trophic interactions. Fishing at lower trophic levels negatively impacted the ecosystem than when fishing was directed to high trophic level species. The system showed resilience and stability when fishing was directed towards top predators. Lake Victoria exhibited top-down characteristics which are usually resistant to fishing.
