Practical Recommendations

Where there is water scarcity, the situation is dramatic for aquatic ecosystems. In many Mediterranean basins the exploitation of water resources has gone clearly beyond renewable level and affects aquatic ecosystems. Thus, they may benefit from the recycling of high-quality effluents that can be used to cope with environmental water demands instead of being discharged. Their reclamation with natural technologies produces an improvement in quality based on the development of trophic webs built upon nutrients still dissolved in the reclaimed water. The main project in the Costa Brava area is that of the Empuriabrava constructed wetland system, where nitrified effluent is further treated to reduce the concentration of nutrients in the water and is reused for environmental enhancement. This facility is also an interesting site for bird-watching. Other projects where water recycling produces indirect benefits on the aquatic ecosystems are those in Tossa de Mar, affecting the “temporary” Tossa Creek (a watercourse which flows on temporary basis according to rainfall patterns), and in the Aro Valley, affecting the also “temporary”, but slightly bigger, Ridaura River. This document summarizes these projects and proposes practical recommendations for the use of treated effluents in the recreation and restoration of aquatic ecosystems.

Coercive Mating

Sexual conflict occurs when the evolutionary interests of the sexes differ and it broadly applies to decisions over mating, fertilization and parental investment. Recently, a narrower view of sexual conflict has emerged in which direct selection on females to avoid male-imposed costs during mating is considered the distinguishing feature of conflict, while indirect selection is considered negligible. In this view, intersexual selection via sensory bias is seen as the most relevant mechanism by which male traits that harm females evolve, with antagonistic coevolution between female preferences and male manipulation following. Under this narrower framework, female preference and resistance have been synonymized because both result in a mating bias, and similarly male display and coercion are not distinguished. Our recent work on genital evolution in waterfowl has highlighted problems with this approach. In waterfowl, preference and resistance are distinct components of female phenotype, and display and coercion are independent male strategies. Female preference for male displays result in mate choice, while forced copulations by unpreferred males result in resistance to prevent these males from achieving matings and fertilizations. Genital elaborations in female waterfowl appear to function in reinforcing female preference to maintain the indirect benefits of choice rather than to reduce the direct costs of coercive mating. We propose a return to a broader view of conflict where indirect selection and intrasexual selection are considered important in the evolution of conflict.

The Impact

The link between psoriasis and sport is a controversial issue. The topic has been poorly investigated, and nowadays there are many unsolved questions, dealing with the role of psoriasis in influencing the sporting habits of patients and, vice versa, the impact of sport activity on course, severity and extent of the disease, with particular regard to the indirect benefits on cardiovascular risk and metabolic syndrome. Moreover, the role of physical activity on patients’ quality of life and the potential limitations on physical activity due to joint involvement have not been well elucidated until now. In this narrative review we will try to provide answers to these queries.

The purpose of the research is to present to the Brazilian municipalities, in particular, to the people of Paraná, a methodology for the formation of municipalities public consortia, in order to assist them to comply with federal legislation regarding the National Program for the Management of Urban Solid Waste. In this context, the survey outlined the consortium structure in Brazil, as well as the conventional systematics of the management of Urban Solid Waste, as well as its destination and reuse, as well as evaluating successful initiatives in other nations. Allied to this, the research also proposes to evaluate two technologies for the destination and treatment of Urban Solid Waste. The character of the evaluation is to analyze, identify and compare results between them. The project focused on a traditional technology that is the landfill and in another that is an innovative technology, which is gasification. The focus of the research is to highlight the importance of cooperative intelligence, especially when there are common problems, in the search for joint solutions, as well as to present technological alternatives that, in addition to providing a solution to the problem of management and destination of Urban Solid Waste, can contribute to The achievement of direct and indirect benefits, both in the environmental, social and economic sphere, the basis of sustainability. For that, the work had as methodological reference the realization of technical visits in both the Cascavel Sanitary Landfill, in the State of Paraná, as well as in the Carbogás Pilot Project in Mauá, State of São Paulo. The results obtained consisted in the presentation of a referential methodology for the formation of municipalities Consortia, as well as comparative results among the technological models that can aid in decision making.

Tingginya intensitas aktivitas penangkapan ikan telah menyebabkan degradasi sumber daya ikan pada beberapa daerah penangkapan ikan. Salah satu langkah untuk menjaga keberlanjutan dan meminimalkan degradasi sumber daya ikan adalah membentuk kawasan konservasi laut daerah. Penelitian ini bertujuan untuk mengetahui pemanfaatan dan pengelolaan Kawasan Konservasi Laut Daerah (KKLD) Gili Sulat-Gili Lawang, Provinsi Nusa Tenggara Barat. Penelitian menggunakan metode valuasi ekonomi sumber daya untuk menganalisis gabungan data primer dan sekunder. Hasil penelitian menunjukkan total nilai manfaat KKLD Gili Sulat-Gili Lawang adalah Rp 8,99 milyar per tahun yang meliputi manfaat langsung dan tidak langsung. Hasil penelitian menunjukan pengelolaan terhadap KKLD ditinjau dari biaya, aktor atau pelaku dan aktivitas pengelolaan sampai saat ini belum optimal. Penelitian ini menyarankan perlunya menyusun strategi pengelolaan yang tepat untuk mengoptimalkan maksud dan tujuan dibentuknya KKLD. Tittle:  Utilization and Management of The Gili Sulat and The Gili Lawang Regional Marine Conservation Area.Highly intensive of fishing activities lead to degradation of fish resources in some fishing grounds. One effort to maintain sustainability of fish resources and minimize its degradation is to establish local marine conservation areas. This study aims to analyze utilization and management of Gili Sulat-Gili Lawang local marine conservation areas (or locally known as KKLD) in Wes Nusa Tenggara Province. This study applies economic valuation methods to analyze combination of primary and secondary data. Results of this study show that annual total benefit values of Gili Sulat-Gili Gili Lawang KKLD is IDR 8,99 billion which includes direct and indirect benefits. In terms of costs, actors and management activities, current management of KKLD is less optimal. Therefore, this study recommends to develop appropriate management strategies to optimize the purposes of KKLD establishment.

The City

The efficiency of any police action depends on the relative magnitude of its crime-reducing benefits and legitimacy costs. Policing strategies that are socially efficient at the city level may be harmful at the local level, because the distribution of direct costs and benefits of police actions that reduce victimization is not the same as the distribution of indirect benefits of feeling safe. In the United States, the local misallocation of police resources is disproportionately borne by Black and Hispanic individuals. Despite the complexity of this particular problem, the incentives facing both police departments and police officers tend to be structured as if the goals of policing were simple—to reduce crime by as much as possible. Formal data collection on the crime reducing-benefits of policing, and not the legitimacy costs, produce s further incentives to provide more engagement than may be efficient in any specific encounter, at both the officer and departmental level. There is currently little evidence as to what screening, training, or monitoring strategies are most effective at encouraging individual officers to balance the crime reducing benefits and legitimacy costs of their actions.
