Small islands are often promoted as a tourism destination in spite of the limited fresh water resources availability that they could retain for daily needs. In this context, efforts to provide fresh water resources sustainable in the small island are necessary to support the tourism destination purpose. This study aims to estimate the carrying capacity of the fresh water resources in Pari Island. The estimation method is the ratio between the fresh water availability and its demand by calculating the island size, aquifer thickness, annual rainfall, hydraulic conductivity or soil permeability, and the application of rainwater harvesting technology (RHT). The result shows that the carrying capacity of the fresh water resources without technological intervention in Pari Island is 2.05. Even though this score indicates the safe level, the measure has not taken the water quality into consideration yet. Expectedly, it could be improved by applying the RHT technology but it results in the carrying capacity score of 1.37 and 1.47 (conditionally safe) for the current state and 25-year future prediction respectively. This study recommends the improvements in tourism management by limiting the visitor number in order to support their sustainability for the local livelihood and Pari Island’s ecosystem conservation.

Water Resources Carrying Capacity

The development of Yogyakarta Urban Area has spread to its surroundings. As a result, water resources carrying capacity and environmental problems are worsening. Rainwater harvesting (RWH) development as part of green infrastructure is one of the important methods to increase water resources carrying capacity. Relating to the problem, this research was conducted in Yogyakarta Urban Area. The study was a combination of field research and studio analysis. The field study measured the settlement’s physical parameters and surveyed the community’s socio-economic and cultural aspects. According to the physical and economic analysis based on CBR, the recommended models of water resource conservation infrastructure were absorption well/1.10; conservation pond/4.53; open space/7.47; and green space/3.59. Meanwhile, rainwater reservoir was not suggested because the CBR value was only 0.18.

The Jaffna Peninsula lie in the northern-most part of Sri Lanka. It is separated from the mainland by two external lagoons. The Jaffna Peninsula depends for its water on the rainfall which percolates and stored in lime stone aquifers. The average annual rainfall is 1284 mm/year and the potential vapour transpiration is 1858.8 mm. The Jaffna Peninsula is struggling to meet the water demand and quality of available ground water also threatened by pollutants. The major aquifers within Jaffna Peninsula located in Valikamam, Vadamaradchchi and Thenmaradchchi area. From 1966 several surveys and investigations were carried out to find out the water usage pattern, required water and available water, etc. The studies which are carried out in different periods on deriving possible “Safe Yield” from the aquifers of Jaffna Peninsula are showing inconsistent results for the same aquifers. In last few decades the ground water is exposed for the pollution due to over extraction for irrigation lead for sea water intrusion, heavy usage of agro chemicals lead to increase the Nitrate concentration beyond the limit and discharging industrial waste in to ground lead to the contamination of petroleum components.The studies done so far on estimating the availability of groundwater in Jaffna Peninsula have been carried out to certain extent and derived recommendations for “Safe Yield” as well. But the findings are varying with the time period for a specific aquifer. Also the carrying capacity of the aquifers are not clearly studied in detail as the groundwater in Jaffna Peninsula is stored in fractured weak limestone aquifers. Therefore the over storage of groundwater in the aquifers beyond their capacity may cause adverse impact to the environment.Based on the past studies, the recommended total “Safe Yield” from the aquifers in Jaffna Peninsula is 13,100 m3 per day in dry season and 34,600 m3 per day in wet season while having a basic water requirement for domestic need of 31,500 m3 per day. Further available annual water resources is 718 m3 per day per person which is less than the recommended amount in the World Water Development Report of the United Nations. These are indicating that the Jaffna Peninsula is facing the water scarcity.The availability of groundwater and the possible additional recharge shall be studied with correlation to the carrying capacity of the aquifer to ensure and improve the available water resources in a sustainable manner. This paper is analysed and summarised the past studies on groundwater in Jaffna Peninsula.

Abstract Carrying capacity and environmental capacity of water resources is the ability of the water to support human life, other living creatures, and the balance between the two as well as the ability of the environment to absorb substances, energy and other components that enter or are incorporated into it. The purpose of this research is to analyze the level of carrying capacity and environmental capacity of water resources in several regencies in Maluku Province, Indonesia. The results showed that some water resources were already in a low environmenttal capacity due to limited availability, especially deep groundwater in Wamar Island, Aru Archipelago Regency and the environmental capacity of water resources had exceeded the quality standards set in Indonesia, especially fresh water in Southeast Maluku Regency and Ambon City. Meanwhile, the environmental capacity of fresh water that has exceeded the quality standard is due to the presence of e-colly bacteria. This condition shows the importance of water conservation through regulating human behavior that is not environmentally friendly, building rainwater control and runoff control infrastructure as well as law enforcement efforts related to watershed maintenance and the behavior of communities around water resources.

Abstract Pramuka Island is a small island that is covered with dense settlements, inhabited by 1,715 people, and experiencing rapid population growth with increasing visits by tourists every year ]. As a result, there is a high demand for freshwater, leading to a large-scale exploitation of groundwater on the island. Yet, a research conducted by [1] had indicated that groundwater on Pramuka Island is below the minimum standards for drinking water. This report discusses the effectivity of a rainwater harvesting system as a solution to the freshwater carrying capacity of Pramuka Island. The discussion involves analysis of freshwater carrying capacity based on water balance calculations between freshwater supply with rainwater harvesting and potential freshwater demands for domestic usage, tourism, and other activities. The results revealed that the scenario of the whole island as a rainwater catchment area is enough to supply local freshwater demand for approximately 27 years.

The article examines the problem of fresh water, since in terms of water supply from its own resources per capita and per 1 km2, the republic is 8 times behind Georgia, 2 times behind Armenia. Significant water consumption in Azerbaijan is caused by its arid territory with a predominance of active temperature and a lack of precipitation, which leads to intensive irrigation of crops. At the same time, artificial irrigation is used on 70% of the cultivated land.
