Coastal zone management requires an understanding of the complex milieu of interactions and activities taking place in an environmental system. Man is beginning to recognize that the old method of dealing with individual issues and problems as single fragment of a whole ecosystem is not enough. This paper tries to deal with the integrated manner in carrying out effectively the management of the coastal zone in Puerto Galera, Oriental Mindoro by the Man and the Biosphere Interagency Committee on Ecological Studies. To attain the objective of the project, the different agencies monitor, identify, observe, investigate various natural and physical parameters contributing to the ecological balance and study the rational use of the resources along the coastal zone. Result of the study showed that although such factors as land use practices of shifting cultivation (kaingin), human attitude towards forest and its resources, and continuous increase in population and migration of people were observed, such pressure on lands has not greatly affected the Puerto Galera coastal zone resources.

The coastal territory is a complex socio-ecological system (SES), which needs to be governed using an integrated approach. Integrated coastal management (ICM) is considered as the main approach in coastal governance, offering a holistic view of the coastal zone by integrating different governance sectors and governance levels, but ICM is not a fixed approach and should be adopted to meet each particular unique national and local situation. Full scale ICM in Latvia is not applied, but the following problems are recognized as most significant in the coastal territory: the lack of qualitative infrastructure and the lack of good governance; the local level coastal SES is studied, monitored and evaluated insufficiently as well as good practice examples are not communicated enough. In the current study, the exploration of the legisla-tive regulations and planning documents was conducted, therefore, the main research methods are docu-ment studies and expert interviews. Both the vertical and horizontal integration were assessed for the coastal governance, as well as overview of ICM developments in the modern history of Latvia. In order to understand the situation of the coastal governance in Latvia, the scheme of coastal dune protection zone was prepared, based on Latvian coastal legislation, however it is often difficult to depict different protec-tion zones in practice in such a dynamic and changing territory as a coastal zone.

Abstract The concentration of human activities in coastal cities results in the increase of nutrient salts released into the coastal environment and is identified as a major environmental problem for coastal zone management. Large amounts of nitrogen and phosphorus are transported by rainwater-runoff from urban catchments to coastal zones during episodic rainfall events inducing eutrophication problems and increasing the risk of red tide occurrence. This study used a coupled model based on the Storm Water Management Model (SWMM) and Environment Fluid Dynamic Code (EFDC) to simulate the rainfall-runoff pollution load and its effects on eutrophication in Shenzhen Bay, southern China. A storm event of 2014 was used to build the modeling scenarios and thus analyzed the spatial-temporal variation of the rainfall-runoff pollution. The results indicated that: (i) rainfall-runoff pollution loads accounted for 60–80% of the total pollution loads, and rainfall-runoff pollution can result in a short-term impact pollution load on the receiving seawater body; (ii) the transportation of nutrient salts in the coastal zone and the nutrient salts absorbing process by algae are at different times, which suggests urban rainfall-runoff pollution has evidently an effect on variation of the concentration of chlorophyll-A in the bay, and with increasing distance to the city, the seawater body is gradually less affected by rainfall-runoff pollution.
