“…In addition, there exists a large mathematical literature on optimal harvesting (although with little or no economic content; see e.g. Brokate 1985;Getz and Haight 1989;Murphy and Smith 1990) and a related literature in forestry economics (see Xabadia and Goetz 2010, and the references therein). Skonhoft et al (2011) analyze selectivity in a three-stage model and find that only few straightforward results appear.…”

Growth Overfishing: The Race to Fish Extends to the Dimension of Size

The gravity of growth overfishing is increasingly recognized. The size-distribution of fish stocks is often severely truncated, even when the overall biomass is reasonably well managed. In a first part of this article, I show how the "race to fish" extends to the dimension of size: Akin to the classical Bertrand competition in prices, each agent has an incentive to target fish at a smaller size. In fact, for perfect selectivity, competition between two agents is sufficient to dissipate all rents. In a second part of this article, I explore the implications of size-differentiated harvesting for ITQ regulation. I show that quotas specified in terms of numbers are far superior to those specified in terms of weight or value.

“…Formula Faustmann telah pula diaplikasi untuk hutan tak seumur di Eropa (Joseph Buongiorno, Holvorsen, Bollandsas, Gobakken, & Hofstad, 2012;Xabadia & Goetz, 2010). Beberapa penelitian telah pula dilakukan di hutan alam tropis yang multi-spesies dan multi-umur menggunakan formula Faustmann seperti di hutan alam Dipterokarpa di Kalimantan (Ingram & Buongiorno, 1996;G.A.…”

ABSTRAKDalam literatur tentang ekonomi kehutanan, formula Faustmann banyak digunakan dalam menyelesaikan masalah maksimasi keuntungan dalam manajemen hutan, terutama di hutan tanaman. Modifikasi model dari formula Faustmann untuk dapat diaplikasikan dalam sistem silvikultur tebang pilih telah diteliti secara luas pada multi spesies dan multi kelas umur. Pada umumnya pengelola hutan alam di Indonesia belum mengadopsi formula Faustmann dalam pengelolaan hutannya. Aspek kelestarian dalam pengelolaan hutan alam umumnya diaplikasikan berdasarkan pada pertimbangan silvikultur, yaitu menghitung potensi tegakan tinggal yang dapat dipanen pada daur berikutnya. Penelitian ini bertujuan untuk menganalisis penerapan formula Faustmann dalam sistem silvikultur hutan alam di Indonesia (i.e. Tebang Pilih Tanam Indonesia) sehingga pengelola hutan alam dapat memperoleh keuntungan yang maksimal dan berkelanjutan. Penelitian ini merupakan penelitian kualitatif yang berdasarkan studi pustaka. Hasil penelitian ini menunjukkan bahwa dengan menggunakan model pertumbuhan tegakan deterministik (i.e. model matriks transisi) dan model kerusakan tegakan tinggal yang baik (i.e. matriks transisi dengan perbedaan proporsi kerusakan tiap jenis dan kelas diameter pohon), formula Faustmann dapat digunakan dalam sistem silvikultur Tebang Pilih Tanam Indonesia. Kata kunci: Formula Faustmann, tebang pilih, hutan alam, Indonesia ABSTRACT PENDAHULUANPengelolaan hutan alam di Indonesia memiliki karakteristik multi-spesies dan multi-umur yang memerlukan berbagai pertimbangan termasuk pertimbangan ekonomi agar keuntungan yang diperoleh dari kegiatan tersebut dapat maksimal. Sistem silvikultur hutan alam yang berlaku di Indonesia adalah sistem tebang pilih (Tebang Pilih Tanam Indonesia/TPTI), yaitu hanya memanen jenisjenis komersial yang memiliki diameter lebih besar dari yang ditentukan. Penentuan limit diameter yang boleh ditebang ini adalah dalam rangka menjamin kelestarian hutan, yaitu diasumsikan setelah siklus tebangan berikutnya, potensi hutan (kubikasi kayu

Abstract. In this paper, the problem of palm oil plantation management is considered. A non-linear mathematical model is proposed considering two state variables as the density of the young palm oil trees and the part of biomass that can produce oil. In the modelling process, it is assumed that the rate of planting new young trees and the rate of felling inefficient trees can be controlled. It is further assumed that the oil production rate is directly proportional to the biomass of palm oil plantation. A system of delay differential equations is developed to study the behaviour of palm oil plantation. The resulting optimal control problem is also solved to estimate the control variables while the objective is to maintain the biomass at a certain level and maximize the oil palm production in a long period. Numerical simulations are given to illustrate the results.
