Natural resource management instruments • The Key Question • How do we, at any location, get • the right intervention • at the right location • at the least cost, • so as to facilitate, from a social perspective • optimal land use change • optimal land and water use?
The full range of opportunities • Outcome-orientated • Informational instruments • Motivational instruments • Regulatory instruments • Market-based instruments • Financial instruments • Property-right instruments • Process orientated • Governance arrangements • Consultative arrangements
What are Market Instruments? • … policy tools that use market signals and processes to encourage behaviour • Seek to induced behavioral change • Foster change • Offer compliance flexibility • Through variation in compliance costs exits
Types of market instruments MBIs ‘encourage behaviour through market signals rather than through explicit directives’ Market-Like Instruments Create business opportunity to sell a service Price - based Quantity - based Market friction Lever behavioural Lever behavioural Lever behavioural change by changing change by specifying change by making prices in existing the ‘amount’ of new existing private markets rights / obligations markets work better Eg: Changing taxes, Eg: Introducing a ‘cap Eg: Disclosing Eg: Auctions & tenders introducing levies, and trade’ scheme or information such as giving subsidies an offset scheme via ecolabelling
Market Friction Instruments • Best left in private sector with catalytic inputs from Government • Typically start in niche markets • Fisheries • Timber Certification • Organic Food Markets • Supply to large wholesale businesses
Price v’s Quantity design choice • In theory, both approaches can yield the same outcome at the same cost • … in practice many factors influencing instrument type and design a key factor is relative uncertainties • Price instruments • Alter the prices of goods / services to reflect their environmental impact • … provides certainty as to compliance costs • Quantity instruments • Control the quantity of the good / service to socially desired level • … provides certainty as to environmental outcome
Instrument choice • Screen for feasibility • Assess potential to deliver environmental goals • On their own? • In combination with other instruments • Recognise variation in human response to same instrument • Assess potential to combine instruments to reduce cost of achieving outcome • Design and develop implementation sequence

Off-set schemes • Most cost-effective when impacts is linked to a development or controllable land-use change • Conflict with Planning Culture of protection for existing uses
Water Land Tradeable Rights Price Robust Water Allocation Single title to Land & Water
Robustness • Robust (adj.) Said of a system that has demonstrated an ability to recover gracefully from the whole range of exceptional inputs and situations in a given environment. • One step below bulletproof. • Carries the additional connotation of elegance in addition to just careful attention to detail. • Compare smart, oppose brittle. • Robust systems • Endure without the need to change their foundations. • They last for centuries. • Inspire confidence. • Produce efficient and politically acceptable outcomes in an ever changing world.
Theoretical Design Foundations • Tinbergen Principle (NP in 1969) • For dynamic efficiency => One instrument per objective • Mundell’s Assignment Principle (NP in 1999) • For dynamic stability => Pair instruments and objectives for greatest leverage • Coase Theorem (NP in 1999) • To minimise adverse effects of entitlement mis-allocation on economic activity => Ensure very low transaction costs
Practical Enduring Experience • Structures that have stood the test of time • Limited liability share companies • Money • Banking systems • Double entry book keeping • Torrens Land Title System
Partitioning the Problem • Need instruments for • Managing individual users • Entitlements • Allocations • Use approvals • Managing aggregate consequences • Water allocation plans to allocate equitably • Trading Protocols to allow efficiency production • Catchment management plans to manage environmental impacts
Goals, Objectives & Targets • Distributive Equity • Economic Efficiency • Manage Environmental Externalities
The CoAG Communiqué • “A key focus of the National Water Initiative will be to implement a robust framework for water access entitlements • …. while ensuring that there is sufficient water available to maintain healthy rivers and aquifers. • …. Under the National Water Initiative, jurisdictions will establish a robust, transparent regulatory water accounting framework that protects the integrity of entitlements.”

Whereas the inhabitantsof South Australia are subjected to loses, heavy costs, and much perplexity, by reason that the laws relating to the transfer and encumbrance of freehold and other interests in land are complex, cumbrous and unsuited to the requirements of the said inhabitants, it is therefore expedient to amend the said Act
Defining entitlements • Unit shares that define an entitlement to a proportional of a defined consumptive pool • Unbundled from other part of the system • Share Registers guaranteed and mortgageable • Fully tradable anyone can own/invest
Risk - A community guarantee? • Guarantee to only use market mechanisms to change allocations • Effectively, insure water users against change in their share of the pool in return for a small return to the Community • Start in 2015 @ 0.5% pa • increase gradually to rate for crown agricultural leases • Place returns in an Environment Trust

Two new MDBC reports on 6 “risks” In 20 years, a further reduction in flow of around 2,500 – 5,500GL. Effects below dams and hence outside release rules erode flows most.

Known accounting solutions • Offset the flow reducing effects of establishing permanent vegetation, clay spreading etc by surrendering an entitlement equivalent to the expected mean effect • Defining tradable entitlement as a “nett” entitlement to prevent increased WUE erosion (return flow reduction) • Defining salinity interception as a water use and acquiring the necessary water from below the cap. Changes the cost benefit of most schemes! • Amending the cap to include all unconfined groundwater within, say, 10kms of the River as part of the system
Water allocation plans • Rules to partition water into • “use” pool (share pool) • “flow” pool • Dam management rules • Share pool reliability and partitioning • High security shares • “General” security • Inter seasonal carry forward and borrowing rules
Catchment plans • Rules for • Applying water to land • Managing drainage and salinity impacts
Pricing • Water supply charges • Fixed charge to cover infrastructure and management • Variable charge to cover costs of supply • Market Value • Allocation prices reveal seasonal opportunity cost • Entitlement prices reveal value of long term economic opportunity • Environment costs • Via salinity and other policies

Over allocation • Exists because • Entitlements are defined in volumes and not as shares of available water in a pool • Plans assume that constant technology and land use change • Introduction of trading that activated previously unused water • Solutions • Buy back • Pro-rata reduction
