The paper aims to investigate the economies of scale of Water Users’ Associations (WUA) in Tunisia. During the last years there has been a lot of discussion in Tunisia about the optimal size of WUAs, which allows more efficient management of the water resources at the local level. In this work...

With increasing water scarcity, research on policy options for improved water allocation and governance becomes an urgent priority for many developing and developed countries. Evaluating institutional alternatives is however a challenging task. This article takes a comparative approach and...

To ensure efficient water allocation and use, policy designers have adopted various strategies, including price setting, decentralising irrigation water management or improving water rights. Most of these strategies have been applied individually, without considering the complementary...

All deviations from the frontier is inefficiency in deterministic DEA (DDEA); thus making the DDEA unable to accommodate the measurement and specification errors. But, most of the production relationships are stochastic in nature with some inputs fixed in the short run. This paper addressed the...

There is no consensus among researchers on the influence of scarcity on common pool resource use: some suggest that scarcity leads to prudent use, whereas others suggest that it will cause over-extraction of resources. This issue is particularly of interest for developing countries, where...

There are growing concerns about illegal activities in the forestry sector and some work is in progress to understand the causes and consequences of noncompliance to forestry laws. However, most research on illegal forest activities deals with illegal timber harvesting with little efforts on...

Payment for Environmental or Ecosystem Services (PES) is among the tools for managing degraded ecosystems and their associated ecological and economic services. Wetlands are an important type of ecosystem, which are highly degradable and accordingly PES become relevant for the sustainable...

In the hard rock areas of India, overdraft of groundwater has led to negative externalities, increases costs of groundwater irrigation and causes welfare losses. Groundwater markets are slowly emerging as niche markets to improve water distribution and to mitigate water scarcity by stimulating...
