The environmental recovery of coastal ecosystems is an environmental management initiative for consultation among the main actors in the development of a city. This work presents an environmental recovery proposal that includes certain management instruments, aimed at reversing the situation of environmental degradation of the coastal waters of Chancay Bay. Due to the importance of the town of Chancay at the regional level and due to the complexity of its environmental problems, this proposal constitutes an alternative of environmental management that can be taken into account in other coastal areas of our territory.

Concerns about environmental problems have increased considerably in recent times. Interest has been given at all levels of government, non-governmental organizations, scientific and technical groups, etc. due to the interrelation between the natural environment and the anthropic environment that are feasible to create risky contingencies. These are approached from three variables: the agent (nature and / or man), the time (before, during and after the event) and lastly, the effects it produces. From an environmental perspective, the industrialization of fishmeal has a significant impact on the ecosystem in which it operates, also affecting the well-being and health of people. This industry is an activity that generates foreign exchange, is a source of employment and contributes to the development of Peru, taking advantage of a resource that is relatively abundant in the Peruvian marine ...

The pollution of coastal waters of the Bay of Chancay caused by the discharge of industrial and urban runoff, has prompted the present investigation aimed to know the extent of contamination of coastal waters of the Bay of Chancay and Impacts, to propose recovery measures and environmental control. As a result of this investigation, it is known that seawater Chancay Bay presents values ​​that are well above current regulations (Water Act), leading in extreme cases to 0.00 ml / l dissolved oxygen, 120 mg / l BOD5, 0.00 bits / ind. diversity, among others, confirming a high pollution.

The city of Chimbote presents fishing as one of its main activities, which makes it consider one of the ports with the highest fishing production in Peru. Other activities are the steel industry, among others. These productive activities are leading this city to a deterioration of the environment, one of its causes being the application of inadequate technologies and the misuse of space. Ecological-economic zoning is considered as a planning instrument, which aims to promote the harmonious development of a territory. The present work proposes a methodology, which approximates the proposal of hierarchization of environmental variables, modified according to Etter, (1990) and consists of evaluating a certain situation, from studies of landscapes, plant associations, pedological studies and climatic, all of static type, without considering the evolution and the flows that define the structu...

The influence of the addition of alkaline mass in the stabilization process of two waste water sludges was studied. The increase in the PH of the sludge, carrying it to values near to twelve, is due to the increase of alkaline mass additions during the stabilization of the residual sludge. This technique was used to stabilize the sludge and to give an agricultural valorization to the residual sludge. In this context, the problematic characteristics present in the sludge will lead us to a preliminary treatment of the sewage sludge.

The “Pintadilla” (Cheilodactylus variegatus Valenciennes, 1833) is a marine species that grows near the coast and is caught by artisanal fishing for human consumption. The objective of this study was to determine the concentration of mercury in this species in both muscle tissue and liver tissue. A total of 32 samples were collected, for 8 months, determining the concentration of total mercury using the cold vapor atomic absorption spectrophotometer. In general, the highest average concentration of total mercury was found in the samples collected in the Chorrillos Artisanal Fishery Market, both for muscle tissue (0.0563-0.2632 mg/kg) and for liver tissue (0.0464-0.2694 mg/kg), with respect to the Ancon Artisanal Fisheries Market, both for muscle tissue (0.0273-0.1193 mg/kg) and for liver tissue (0.0488-0.1911 mg/kg) all on a wet basis.

The wastewater treatment plants in general (WWTP), give as a final result, sludge, which represents approximately 2% of the treated wastewater. In the city of Lima, with increasing population growth, the sludge produced will also be greater and therefore greater environmental pollution will be considered. One of the ways to eliminate them is the energy assessment, that is, calculating the calorific value of the sludge and comparing it with other solid fuels. The work that we present consists of carrying out a chemical, biological, percentage of humidity and fixed carbon analysis of the sludge sample from the WWTP - Ventanilla, finally the calorific value was calculated by the Gouthal method, resulting in (PC = 21667.68J / kg) for the Ventanilla WWTP, then we compare it with other solid fuels such as anthracite (PC 27907.2kJ / kg) and lignite (PC = 9108.57 kJ / kg), making it acceptable t...

The investigation was based on the theoretical and practical aspects for a model of vulnerability to flooding hazard due to climate change, in order to calculate the avoided cost. It takes as a primary characteristic the variable precipitation. The first step has been an account of the state of the art on modelling vulnerability to flooding in Peru. When it comes to modeling floods, a problem arises that stems abundantly from trying to simulate, with discrete expressions in time and space, a progress that occurs in nature on a progressively much smaller scale. The last stage of the investigation consisted of running the model, this phase compares the numerical results with the control measures to be implemented, outcoming a map of different return periods of flooding impact. The main conclusion is that flood modelling is a function of the study area and meteorological variables. Therefor...

The objective of the research was to describe the current problems generated by anthropic action and geodynamic phenomena causing the loss of sandy beaches in the Miraflores - La Chira (Costa Verde) stretch, Lima. Methodologically, the study consisted of the elaboration of the geodynamic map and cross sections at a scale of 1/5000, aimed at the diagnosis of geological risks together with the sedimentological analysis, focused on understanding the general aspects of the dynamics of erosion, transport, deposition and the associated human effect. Likewise, in order to estimate the modification of the beach profile and the most vulnerable areas, aerial photos from 1960 were compared with recent ones. Finally, through the interpretation of the vulnerability index, a valuation of 0.38 and 15.12 was obtained, which corresponds to the moderate level category in both beaches. It is concluded that...
