In this paper we are concerned with private sector participation in natural resource management in developing countries. The paper addresses both the establishment (or formalisation) of private property rights to natural resources, and the private markets in which such rights are exchanged. The...

The conservation of biodiversity is a major environmental issue, one that promises to remain at or near the top of the environmental agenda for the foreseeable future. The loss of biodiversity affects human welfare as well as being lamentable for its own sake. Humans depend on natural systems to...

We present an analytical model for determination of the economically optimal harvest age of a forest stand considering timber value, and the value of carbon fluxes in living biomass, dead organic matter, and wood products pools. Through comparative statics analysis, we find that consideration of...

From ecosystems we derive food and fiber, fuel and pharmaceuticals. Ecosystems mediate local and regional climates, stabilize soils, purify water, and in general provide a nearly endless list of services essential to life as we know it. To understand how to manage these services it is essential...

In this paper an attempt has been made to analyse the behaviour of Lyari River contaminated wastewater to main sea. Main focus is on the sate of water ways and physical, chemical and metallic parameters for effluents. Empirical analysis is done for the proper conclusion and implications. Lyari...

In this communication we utilize an improved version for model proposed by Manning for the waste flow via an open channel Lyari. We have computed the status of discharges, storages and depth for all locations of the Lyari waste flow using this proposed model. We have found that the result...

I conti patrimoniali (asset accounts) sono fra i principali moduli di contabilità ambientale e fanno riferimento alle risorse e agli ecosistemi. Lo sviluppo dei conti patrimoniali delle risorse, grazie a diversi decenni di esperienze e applicazioni, sta giungendo alla standardizzazione delle...

Mitigation and adaptation are the main strategies to address climate change. Both of them are interrelated instruments and key elements of an integral approach to tackle the phenomenon. This interrelation is particularly strong in the land use sector, an area in which practically any policy has...

The environmental system is characterized by an interplay of geophysical and geochemical processes that provide a setting for life. Now that human interventions are affecting the global system as a whole, it is important to distinguish between changes of natural origin and changes brought about...

Danube Delta has suffered damages of habitat and species loss caused by factors, including: construction of dams upstream have degraded obviously flooding regime; creation of agricultural and fishing enclosures which decreased the natural and original surfaces; extending artificial navigation...
