Tigriopus fulvus (Fischer, 1860) is a benthic harpacticoid copepod of the Mediterranean supralittoral zone. The transitional characteristics of this environment forced this species to develop high resistance to changes of environmental parameters. Nevertheless, Tigriopus fulvus life-cycle is influenced from the splashpools physical-chemical parameters. In this paper, we present the results of a supralittoral monitoring performed in 2014, confirming the influence of some of these environmental parameters on population buildups. Because of recent worldwide climate change effects, a threat might have been posed on this particularly exposed organism, whose population density decreased of a sixfold value in the last 30 years. During the three pools (A, B, C) monitoring, the maximum copepod density recorded was 1456 Ind/l (September 2014, Pool C), alongside first records of extinction event for Tigriopus fulvus.

The Impact

The popularity of Floating Homes in Western Europe and North America is noticeable. The interest in these facilities in Poland is also constantly growing. The popularity of Floating Homes is due to climate change, rising land prices and population density in city centers. However, environmental factors play a significant role in their development. The publication presents the results of research on the impact of environmental factors on the development of Floating Homes in Poland. As part of the research, the most important environmental factors were identified and then, using the State of the Surroundings Scenarios (SSS) method, an initial scenario of their development was developed. The most probable scenario was developed, the purpose of which was to identify the most favorable factors - strengths and unfavorable factors - weaknesses responsible for the development opportunities of Floating Homes in Poland. Additionally, a surprise scenario was prepared, which indicated factors that may unexpectedly accelerate the development of Floating Homes in Poland or slow it down.

One of the main challenges of the future is the strengthening impact of environmental factors on economic development, in particular, environmental threats, climate change, waste minimization and reduction of СО2 emissions. At the present stage, achieving sustainable economic development has become an important item on the global agenda. The purpose of this article is to develop the theoretical foundations of the process of greening in the economy and substantiate practical approaches in Ukraine to overcome global climate challenges. To achieve this goal, the author used retrospective research methods, and abstract-logical, economic-statistical and systematic approaches. Based on the analysis of scientific works of foreign and domestic scientists, the article deepens the theoretical foundations of the concept of greening. In particular, it is established that this concept characterizes the improvement of environmental parameters of production through the introduction of technological, organizational and managerial innovations that increase the efficiency of natural resources, reduce man-made impact improve the quality of the environment and increase the level of environmental education and environmental culture of the population and industrial staff. The results of the study showed that in modern conditions the concept of sustainable dependence of the economy on environmental factors has been formed, which is supplemented by the problem of solving global challenges of mankind. This requires the introduction of new economic approaches to addressing the global challenges posed by climate change, among which the introduction of the principles of circular economy is important.

Pesisir merupakan kawasan yang rentan mengalami penurunan kualitas perairan akibat masuknya bahan-bahan pencemar hasil aktivitas antropogenik dari daratan. Penelitian ini bertujuan untuk untuk mengkaji kualitas perairan berdasarkan keanekaragaman meiofauna dan parameter fisika-kimia di pesisir Losari, Makassar. Selain itu penelitian ini dilakukan untuk menganalisis pengaruh parameter fisika-kimia terhadap keanekaragaman meiofauna di dasar perairan. Penelitian ini bersifat kuantitatif dengan teknik pengambilan data secara purposive sampling. Status kualitas perairan di pesisir Losari dikategorikan sebagai perairan yang tercemar berat, hal ini didasarkan pada tingkat keanekaragaman spesies meiofauna yang sangat rendah dan sebagian besar parameter fisika-kimia perairan yang tidak memenuhi baku mutu yang telah ditentukan oleh pemerintah RI melalui Kep. MLH. No. 51 Tahun 2004. Kecerahan, DO, Suhu, kedalaman, salinitas, dan nitrat sedimen merupakan parameter fisika-kimia yang berkorelasi positif atau berpengaruh terhadap tingkat keanekaragaman meiofauna. Adapun parameter lingkungan perairan yang berkorelasi negatif terhadap tingkat keanekaragaman meiofauna di pesisir Losari, diartikan sebagai hubungan yang tidak menguntungkan. Kondisi ini terjadi akibat meiofauna merasa terganggu atas sebaran fosfat sedimen, nitrat air laut, fosfat air laut, dan pH yang tidak memenuhi baku mutu air laut.ABSTRACTThe Coastal zone are susceptible to decreasing water quality due entry of pollutants from anthropogenic activities in the mainland. This study assessed water quality based on meiofauna diversity and physical-chemical parameters in the Losari coast, Makassar. Furthermore, this study was to analyze the physical-chemical parameters effect on the diversity of meiofauna at the seabed. It employed a quantitative approach with purposive sampling technique. Water quality status on the Losari coast categorized as heavily polluted waters, this based on low level of meiofauna species diversity and most of the physical-chemical parameters does not meet the quality standards determined by Indonesian government through Kep. MLH. No. 51 of 2004. Brightness, DO, temperature, depth, salinity, and sediment nitrate are physical-chemical parameters positively correlated or influenced of meiofauna diversity level. The aquatic environmental parameters negatively correlated with meiofauna diversity level in the Losari coast are interpreted as an unfavorable relationship. This condition occurs because the meiofauna feel disturbed by distribution of sedimentary phosphate, seawater nitrate, seawater phosphate, and pH that does not meet seawater quality regulations.

The Itajaí-Mirim River located in Santa Catarina, in the region of the low estuary of the Itajaí-Açu River, is the place where most of the water supplied for consumption is consumed by the Municipalities of Itajaí and Navegantes, the São Roque catchment station. This study aims to analyze the water quality in the Itajaí-Mirim river before and after the implantation of the dam in the Itajaí-Mirim river, based on a monitoring of physical-chemical parameters. The collections described in this report were carried out at six sample points, from January to December 2007, with the purpose of physically and chemically characterizing the environment in the rectified channel and, also, in the original bed of Itajaí-Mirim. The parameters measured in situ serve to assess the general state of water quality at the time of sampling. The main parameters measured, four of them deserve special attention (pH, Turbidity, Dissolved Oxygen and Salinity) and the correlated environmental parameters were flow rate and precipitation. In general, depending on the main results obtained, the analyzed waters can be classified in Class 2 of fresh waters, according to the limit values of CONAMA Resolution No. 357/05, and for the sampled period, precipitation and flow influenced the water quality.

Abstract. Human migration is both motivated and constrained by a multitude of socioeconomic and environmental factors, including climate-related factors. Climatic factors exert an influence on local and regional population density. Here, we examine the implications of future motivation for humans to migrate by analyzing today's relationships between climatic factors and population density, with all other factors held constant. Such “all other factors held constant” analyses are unlikely to make quantitatively accurate predictions, but the order of magnitude and spatial pattern that come out of such an analysis can be useful when considering the influence of climate change on the possible scale and pattern of future incentives to migrate. Our results indicate that, within decades, climate change may provide hundreds of millions of people with additional incentive to migrate, largely from warm tropical and subtropical countries to cooler temperate countries, with India being the country with the greatest number of people with additional incentive to migrate. These climate-driven incentives would be among the broader constellation of incentives that influence migration decisions. Areas with the highest projected population growth rates tend to be areas that are likely to be most adversely affected by climate change.

In Southeast Sulawesi rehabilitation of mangrove areas that have been damaged but in reality not all mangrove rehabilitation activities were successful, this was allegedly caused by a mismatch in the type of mangrove and incompatibility of rehabilitation techniques used with environmental conditions or parameters of the local coastal environment. This study is aimed to analyze the condition of coastal environmental parameters in Bungkutoko island, district of Abeli in rehabilitation proposed of mangrove ecosystem and to find a proper rehabilitation strategy for it can be applied in that area. This study was carried on June to July 2009 in the coastal of Bungkutoko island, Abeli district, Kendari Town. Data in this study is analyzed as descriptively for giving common view of that area. The measurement results of several physical-chemical parameters on the coast of Bungkutoko island at stations I, II and III are suitable for mangrove ecosystem rehabilitation activities, which have a slope of the base: flat and sloping, particle size: small substrate, binding capacity of substrate particles: moderate to loose, confinement coastline: protected and semi protected and open, wave: relatively small, sea level deviation: moderate, tidal type: mixture tends to double daily, current speed: weak, sediment suspension: normal and salinity: 25-35 ppt. Also pay attention to the right planting time on the condition of mangrove tree is in having fruits and calm water condition of sea. And for planting technic is propaguls directly planted to the ground and using seeds on the polybags.
