Economic valuation of environmental goods in water resources.

We investigated the application of economic instruments in the management of Brazilian water resources as mechanisms to stimulate the rational use of water and to recognise its economic value. We analysed water-charge scenarios at the national and international levels as a methodology to provide an economic estimate of environmental services related to water resources. Through bibliographical and documentary research, we identified the economic instruments applied to Brazilian water-resource management, describing the methodologies and values used Brazilian water charges and in some member states of the Organization for Economic Cooperation and Development. We identified how economic valuation methods of environmental resources could contribute to the improvement of water charges, considering the environmental services offered by a healthy river basin. In the Brazilian and the international scenarios, water charge methodologies include the volumetry of abstracted or consumed water, associating some elements that indicate the pollution level. The prices per cubic meter of water are still very low in all the scenarios. Environmental valuation techniques can be an essential tool for rethinking the methodologies and costs applied in water charges, increasing the potential of water’s rational use through economic instruments.

Economic Valuation

Masalah yang dikaji dalam penelitian ini adalah analisis jumlah sedimen dalam kantung embung dan valuasi ekonomi sumberdaya air embung, dengan mengambil 3 (tiga) lokasi embung di Kota Kupang. Tujuan dari penelitian ini menghitung dan mengetahui jumlah sedimen dalam kantung embung dan valuasi ekonomi sumberdaya air embung. Hasil perhitungan sedimen embung Nononesnab diperoleh jumlah sedimen sebesar 1382,96 m3, embung Nonopasi sebesar 976,82 m3, dan embung Kampung Lama sebesar 186,18 m3. Nilai valuasi ekonomi sumberdaya air embung dilihat dari hasil perhitungan Total WTP sebagai berikut, untuk penawaran 1 (satu) embung sebesar Rp. 437.234,04, untuk penawaran 2 (dua) embung sebesar Rp. 295.744,68, untuk penawaran 3 (tiga) embung sebesar Rp.225.531,91, untuk penawaran 4 (empat) embung sebesar Rp. 166.489,36 dan untuk penawaran 5 (lima) embung sebesar Rp. 100.638,30. Dari hasil nilai valuasi ekonomi sumberdaya air embung menunjukkan bahwa semakin tinggi penawaran penambahan pembangunan embung baru semakin rendah tingkat kesediaan masyarakat untuk membayar. This research has been done to analyse the sediment in quarries and economic valuation of water resources. The locations were at 3 quarries in Kupang City. The result of sediment Nonoesnab quarry was 1.382,96 m3, Nonopasi quarry was 976,82 m3, and Kampung Lama quarry was 186,18 m3. Economic valuation water resources as total WTP as follows, WTP of 1 quarry was Rp. 437.234,04, WTP of 2 quarries was Rp. 295.744,68, WTP of 3 quarries was Rp. 225.531,91,WTP of 4 quarries was Rp. 166.489,36 and WTP of 5 quarries was Rp. 100.638,30. Based on economic valuation of water resources showed that the higher the additional development of the quarry, the lower the public's willingness to pay.
