"The Biology of Lakes and Ponds focuses on the interactions between the abiotic frame, such as turbulence, temperature, pH and nutrients, and the organisms, including interactions with and among organisms at the individual, population and community level. The book fills this niche between traditional limnology and evolutionary ecology by focusing on physiological, morphological and behavioural adaptations among organisms to abiotic and biotic factors and how interactions between biotic processes and abiotic constraints determine the structure and dynamics of lake and pond systems. In addition, the book describes and analyses the causes and consequences of human activities on freshwater organisms and ecosystems and covers longstanding environmental threats, such as eutrophication and acidification, as well as novel threats, such as biodiversity loss, use of everyday chemicals and global climate change. However, also signs of improvement and the possibilities to restore degraded ecosystems are discussed and provide hope for future generations."

"Daerah Khusus Ibukota (DKI) Jakarta adalah Ibu Kota Negara Kesatuan Republik Indonesia. Salah satu permasalahan lingkungan yang terjadi di DKI Jakarta adalah semakin buruknya kondisi ekosistem akuatik, khususnya waduk. Waduk yang ada di DKI Jakarta saat ini memiliki kualitas yang semakin menurun akibat perubahan fungsi daerah tangkapan air waduk. Penelitian ini bertujuan untuk menilai kualitas dan kesehatan waduk berdasarkan metode asesmen yang dikeluarkan oleh Ecological Observation and Wetlands Conservation (Ecoton). Analisis perubahan kondisi kualitas dan kesehatan waduk di DKI Jakarta dilakukan berdasarkan data tahun 2010 – 2019. Penelitian dilakukan pada 10 waduk yang terletak di wilayah DKI Jakarta. Pemilihan sepuluh waduk tersebut merepresentasikan kualitas serta kesehatan waduk di lima kotamadya DKI Jakarta. Penelitian ini menggunakan data sekunder dengan tiga variabel utama dalam menentukan kualitas dan kesehatan waduk yaitu persentase tutupan lahan, data kualitas air waduk, dan data kondisi sempadan waduk. Analisis dilakukan dalam dua tahap, tahap pertama dilakukan analisis korelasi metode Spearman Rank. Tahap kedua adalah regresi untuk mendapatkan koefisien pengaruh explanatory variable. Disajikan hasil analisis berupa tabel rekapitulasi penilaian kualitas dan kesehatan waduk. Hasil persamaan regresi dapat digunakan sebagai alat untuk memprediksi perubahan kualitas air waduk akibat perubahan tutupan lahan dan kondisi sempadan waduk. Dari hasil time series dapat diketahui bahwa terjadi penurunan kualitas dan kesehatan pada kesepuluh waduk yang ditinjau dalam kurun waktu 10 tahun.

The Special Region of Jakarta is the capital city of the Republic Indonesia. One of the environmental problems that occur in DKI Jakarta is the worsening condition of the aquatic ecosystem, especially reservoirs. The existing reservoir quality in DKI Jakarta is currently of a decreasing due to changes in the function of the reservoir's catchment area. This study aims to assess the quality and health of the reservoir based on the assessment method issued by the Ecological Observation and Wetlands Conservation (Ecoton). Analysis of changes in the quality and health conditions of reservoirs in DKI Jakarta was carried out based on data from 2010 - 2019. The research was conducted in 10 reservoirs located in the DKI Jakarta area that assumed to represent the five municipalities in DKI Jakarta and represents the quality and health of the reservoirs in DKI Jakarta. This study uses secondary data with three main variables in determining the quality and health of the reservoir, land cover data, reservoir water quality data, and reservoir boundary condition data. The analysis was carried out in two stages, the first stage was the Spearman Rank method correlation analysis. The second stage is regression to get the coefficient of the explanatory variable influence. The results can be presented in the form of a recapitulation table for quality assessment and reservoir health. The results of the regression equation can be used as a tool to predict changes in reservoir water quality due to changes in land cover and reservoir boundary conditions. From the results of the time series, it can be seen that there has been a decrease in quality and health in the ten reservoirs reviewed over a period of 10 years."

"ABSTRAKJenis penelitian ini adalah etnografi yang berfokus pada aktivitas pemanfaatan ekosistem danau dan bentuk-bentuk kebijakan pengelolaan yang ditetapkan oleh pemerintah dan kelembagaan adat. Teknik pengumpulan data adalah studi pustaka, observasi partisipasi, dan wawancara mendalam. Lokasi penelitian meliputi empat wilayah kecamatan yang memiliki wilayah danau terluas yakni Kecamatan Tempe, Kecamatan Sabbang Paru, Kecamatan Tanasitolo Dan kecamatan Belawa. Informan adalah masyarakat sekitar danau, tokoh adat, serta kepala dan staf SKPD yang terkait dengan manajemen danau. Penelitian ini menemukan Danau Tempe menjadi sumber daya milik bersama (common property resources) karena dapat dimanfaatkan dan diakses secara bersama oleh semua orang tanpa batasan yang tegas. Bentuk kebijakan pengelolaan danau dirancang dan dibuat oleh pemerintah dan lembaga adat lokal. Bentuk kongkrit kebijakan pengelolaan danau, dijabarkan dalam peraturan daerah serta dalam bentuk system norma, upacara adat dan pamali-pamali, yang pengawasannya dilakukan oleh pembuat kebijakan, serta masyarakat. Secara de yure, Danau tempe dikelola secara kolaborasi (collaborative management ) antara pemerintah dengan lembaga adat, namun secara de facto, fungsi manajemen kolaborasi tidak optimal sehingga Danau Tempe tampak seperti sumber daya yang bisa diakses oleh siapa saja, tanpa aturan ( open access )

ABSTRACTThis research is a ethnography type that focused to the activity of lake ecosystem and forms of management policies set by governments and traditional institutions. The data collection technique is literature, participant observation and deep interviews. Research Location covers four regions districts that had the largest lake district area of Tempe, District Sabbangparu, district Tanasitolo and district Belawa. Informants are people around the lake, traditional leaders and also the heads and staff SKPD who related to lake management. This study found that the lake Tempe as be a common property resources (common property resources) because it can be shared and utilized by all people without clear limits. Forms of lake management policy is designed and made by local government and traditional institutions. Concrete forms of lake management policy, spelled out in local legislation as well as in the form of system norms, ceremonies and taboos-taboos, the monitoring carried out by policy makers and the public. In de yure, Tempe Lake managed in collaboration between the government and indigenous institutions (collaborative management), but de facto, collaboration management functions are not optimal so Tempe lake looks like resources that can be accessed by anyone, without rules (open access) "
