Settlement growth and activity of the population in the Brebes Subdistrict upstream side is also predicted to trigger intrusion and rising sea levels that affect the flow and availability of fresh water needed for the survival of life mangrove vegetation, especially in the adult stage. Therefore, identification of the quality of waters in the mangrove areas is needed to determine the status of these waters pollution index. Measurement of physical and chemical parameters of waters in situ using a Water Quality Checker (DKK TOA WQC Type-24) and laboratory testing of some samples to determine the nutrient content of the water is also performed. Insitu value measurement results later are calculated by using a pollution index refers to the Decree of the State Minister of Environment Number 51 The year 2004 on Guidelines for Determination of Water Quality Status. Index of water pollution Brebes District mangrove area is divided into three criteria: pollution index good condition, lightly polluted and heavily polluted. The section near the front mangrove estuary and enter the index criteria lightly polluted.

Pakerisan watershed is used by the people for various purposes to meet the daily needs for water and it is also for irrigation water. The aim of research was to determine the water quality related to human activities and the pollution index. Water sampling was conducted in the nine sample points i.e. upstream of two sample points, in the middle of four sample points, and in the downstream of three sample points. Sampling was done by purposive sampling. Determination of water quality was carried out by comparing the measured data of each parameter of water with the value of quality standards based on the Bali Governor Regulation Number  08 of 2007, while the definition of the status of water quality was done by the pollution index method. The results showed that the activities that affect the water quality physically, chemically and biologically at the upstream to downstream are farming activities, settlements, tourism and trade. In the upstream showed no parameters that exceeded the quality standards, the variables of BOD, COD, phosphate, fecal coli and total coli exceeded the quality standards and in the downstream,  the BOD, fosfat and  fecal coli exceeded the quality standards. The pollution index found in the upstream region good condition, whereas in the middle was classified as heavily polluted until the downstream  was lightly polluted.

Heritiera fomes Buch.-Ham. is assessed as an endangered mangrove species by IUCN, and information on population status is lacking. The present study assesses the status of H. fomes in Mahanadi Mangrove Wetland on the east coast of India. Three forest blocks were selected and sampled for this study. Among these, the mean girth at breast height (GBH) of H. fomes was the highest in Hetamundia (HD) forest block. GBH of H. fomes was inversely proportional to the cumulative disturbance index (R2= 0.7244, p value <0.005). The relative density was maximum for H. fomes (56%) at Bhitarkharnasi (BK), and for Excoecaria agallocha at Hetamundia (HD; 35%) & Kansaridia (KD; 54%), respectively. Excoecaria agallocha is a dominant species possibly impacting natural populations of H. fomes. Climate change and rising sea levels may also negatively affect the existence of this species. Therefore, appropriate strategies should be taken for conservation of this globally threatened mangrove species prior to its extinction.

The article is an attempt to respond to the need to find international legal solutions, extremely important for people living in the countries threatened by the consequences of climate change, among others, the effects of rising sea levels in the seas and oceans. I try to direct attention to the still underestimated in the international law problem of the so-called "climate refugees". Behind the concept that defies the classic definitions of "refugees", there are hundreds of thousands today, and soon perhaps millions of people whose lives, health and property will be threatened by the forces of nature. The originality of the approach presented in the article is an attempt to consider whether appropriate legal solutions that protect vulnerable populations can be sought on the basis of international humanitarian law, since so far no other branch of international law seemed adequate to take up this challenge. The urgent and important dimension of the problems discussed in the article completes the necessity of searching for and finding answers to questions about the relationship between climate change and public international law. These are the legal consequences of climate deterritorialisation of sovereign states, such as the status of the population of the state without land territory, the loss of territories by archipelago states, the change of the sea borders, territorial waters, exclusive economic zones, and finally the responsibility of states for climate change. In the context of 'climate refugees', there is still no binding legal act that would meet the needs of thousands of people affected by climate change. This causes dissonance because, beyond any doubt, the situation in which these people find themselves raises a lot of fears - for their own lives, safety, health, etc. Today, entire communities and even countries face the problem of progressing deterritorialisation in face of climate threats. climate change, they face the risk of a non-culpable threat to their sovereignty.

Abstract. Baru Barat River is a man made river for flood and irrigation control. This study aims to determine the effect of activities on the bank on Baru Barat River on the water quality. Identification of activities is carried out along the bank of river. Water quality parameters are compared with the Governor of Jakarta no. 582 year 2005. The status of water quality is determined using the Pollution Inde (PI). The activities around the Baru Barat River are settlements, officem workshop, schools, deales, food stall, laundry, shops, beauty salons, guesthouses and gas station. BOD concentration range from 8.4-43.7 mg/L with a quality standard of 10 mg/L and COD range from 16-99.2 mg/L with a quality standard of 20 mg/L. Concentration of BOD and COD that exceed of quality standard at almost all sampling ponts. The level of pollutionj in the Baru Barat River is moderate polluted. The main problem at Baru Barat River are the presence of several illegal waste point left from activities that eventually enter the river and the absence of waste water treatment. The concept of community based must be implemented to waste management and communal wastewater treatment that are easy, inexpensive and integrated with the landscape.

River Bian in Merauke Regency has been utilized by local people in Papua (the Marind) who live along the river for fulfilling their daily needs, such as shower, cloth and dish washing, and even defecation, waste disposal, including domestic waste, as well as for ceremonial activities related to the locally traditional culture. Change in land use for other necessities and domestic activities of the local people have mounted pressures on the status of the River Bian, thus decreasing the quality of the river. This study had objectives to find out and to analyze river water quality and water quality status of the River Bian, and its compliance with water quality standards for ideal use. The study determined sample point by a purposive sampling method, taking the water samples with a grab method. The analysis of the water quality was performed by standard and pollution index methods. The study revealed that the water quality of River Bian, concerning BOD, at the station 3 had exceeded quality threshold. COD parameter for all stations had exceeded the quality threshold for class III. At three stations, there was a decreasing value due to increasing PI, as found at the stations 1, 2, and 3. In other words, River Bian had been lightly contaminated.
