WATERSHED LAND USE ALLOCATION:
POTENTIAL MECHANISMS FOR ADDRESSING
SOCIETAL CONCERNS
Marian S. delos Angeles*
The previous chapter by Cruz (1997) outlined the conceptual
framework for watershed-based forest land-use planning and
emphasized the following objectives of watershed management, to wit:
1. streamflow regulation;
2. soil resource conservation for enhancing on-site productivity,
erosion control and infiltration capacity;
3. optimum production of goods and services;
4. poverty eradication in the uplands; and,
5. environmental stabilization (including climate change
mitigation).
This chapter follows through the process of addressing these
objectives in two parts. First, we summarize a sampling of planning
tools to provide ideas on how multiple objectives for watershed
management may be tackled. Second, we explore the mechanisms for
allocation, with due emphasis on avenues for resolving conflicts.
Finally, future directions for subsequent work are suggested.
PLANNING TOOLS FORWATERSHEDMANAGEMENT
There is no shortage of tools for examining forestland allocation for
addressing multiple objectives. Various attempts include the application
of mathematical optimization models for addressing multiple objectives
and valuation of alternative land-uses.

Among the optimization models are:1
1. goal programming for the Mt. Makiling Forest Reserve
(Balangue, 1979);
2. interactive programming for the Cagayan Valley Region (AraSo,
1985);
3. STEM algorithm application (Contreras, 1985);
4. Iogit decision model for land use allocation (Gregorio, 1990);
and
5. valuation and evaluation of management alternatives for a
mangrove forest (Janssen and Padilla, 1996).
These models vary in terms of their unit of application,
incorporation of on-site and off-site concerns, data used for valuation of
alternative uses, and explicit consideration of the concerns of various
stakeholders.
In terms of unit of analysis, the studies range from the assessment
of land classification units by Gregorio (1990), to analysis of larger
forest areas or regions by the other four studies. Since all five studies
examine multiple objectives, they address both the on-site and off-site
beneficiaries of alternative forestland uses. The first four studies
incorporate off-site considerations such as watershed protection or
keeping sediment loads within a pre-determined limit by including such
concerns among the constraints of the optimization problem.
Additionally, the more recent study by Janssen and Padilla (1996) also
includes global concerns such as biodiversity and carbon emissions.
The first four studies, having been conducted before the nineties,
required considerable inputs for developing the computer programs for
the mathematical optimization problems. In terms of data requirements,
these studies used a combination of stylized facts and information
specific to the area of application that was generated by previous
analysis.
On the other hand, the fifth study by Janssen and Padilla (1996),
having benefited from more recently available, powerful computing
services (both hardware and software) also spent resources for
generating site-specific information. Moreover, the authors, both being
economists, addressed in more detail the potential trade-offs among

efficiency, equity and environmental objectives. In the process, the
concerns of various stakeholders, including the fishpond owners,
fuelwood gatherers, public decision-makers and globally oriented
environmentalists were examined. A similar framework for examining
the political economy of land use allocation was earlier implemented by
Contreras (1985), albeit sans valuation of different goods and services.
The multiple criteria decision models that were explored by
Balangue (1979), AraSo (1985) and Janssen and Padilia (1996) applied
different weights to multiple objectives, reflecting stakeholder
preferences and degrees of importance, to some extent. The authors
unilaterally determined these weights; future applications should
include a process for generating or validating such weights by the
stakeholders concerned.
All these studies are important initial mechanisms for organizing
information in a manner that allows the various parties interested in
different watershed goods and services to assess the options for
watershed management. To resolve conflicts among various uses and
stakeholders, greater effort at valuing goods and services needs to be
exerted that would pave the way for potential allocation mechanisms to
be implemented as outlined in tile next section.
EXPLORING ALLOCATION MECHANISMS
The process for addressing multiple objectives for various
watersheds is getting more complicated by the fact that: most
watersheds either have settlers, are claimed by interested parties, or
both; different agencies and governing units oversee watersheds;
demands for various goods and services are ever increasing; and
institutional arrangements, including property rights, are neither well
defined nor stable.
To minimize the potential for conflict and explicitly address equity
concerns, planning and implementation must be participatory at various
levels. The potential mechanisms for allocation have varying degrees of
participative decision-making. Further, their implementation hinges on
where the property rights are vested and the institutional mechanisms
that are available for resolving competing uses.
The Command and Control Approach (CAC)
The Command and Control Approach characterizes the situation
where the resource manager with prime responsibility for managing a54 JOURNAL OFPHILIPPINEDEVELOPMENT
watershed allocates and regulates its use by other parties through
enforcement of detailed rules and regulations that are unilaterally
determined. The rules may range from broad strokes such as zoning, to
detailed specification of the technologies for using the resource (e.g.,
no portable saws and mini-sawmills). Regulation by rule-making is
implemented through a system of sanctions and penalties on the
violations. This system works if the resource manager is all-knowing (on
supply and demand and on environmental standards) and possesses the
resources required for effective monitoring and enforcement. It is
usually practiced under socialist planning regimes.
The CAC system becomes problematic when there are numerous,
competing users, information on impacts is highly uncertain, the
financial resources for enforcement are not available and the
implementors are corrupt. This centralized system tends to be
expensive to implement and curtails flexibility among users. The
sources of inefficiency, e.g., high cost of achieving desired objectives,
include uniform specification of rules across both high-cost and low-
cost users, lack of incentives for technological development, and the
resources wasted on attempts to circumvent unreasonable regulations.
Examples of the CAC approach include: mandating all forest
licensees to Set up processing facilities at their areas of operation;
requiring all community-based forest operators to practice carabao-
logging, allowing all forest products gatherers to collect amounts
sufficient only for household use, and cutting bans.
The Market-based Instruments Approach (MBI)
The Market-based Instrument Approach simulates the use of
market mechanisms for inducing private user groups to act in a socially
desirable manner. Regulation through the market includes using
economic instruments to modify private behavior and simulating a
market for watershed goods and services. Examples include: using a tax
that reflects damages to penalize the erring user groups; requiring
reforestation bond that is forfeited in case of violation, and bidding out
tradable permits to use a good or service derived from a watershed,
The prime advantage of market-based instruments is flexibility of
choices among the regulated parties. This flexibility brings about lower
cost mechanisms for achieving specific objectives and faster adoption
of alternative technologies.
Market-based mechanisms also require prior information on
environmental standards and monitoring of behavioral change as well asDELOSANGELES: WATERSHEDLAND USEALLOCATION 55
environmental impacts. MBIs work best when there are markets - e.g.,
there are sufficient enough players to preclude collusive behavior.
Examples include transferable development rights (Canada), tradable
water rights (Thailand), royalties paid for exclusive access to gene pools
by pharmaceuticals (Costa Rica), carbon credits/offsets (international
firms), cost recovery for irrigation system fees, and payments for water
sourced from another state in the U.S.A.
Both the CAC and MBI schemes encourage private use,rs of
environmental and natural resources to internalize the social costs of
their actions, although the process of internalization is more flexible for
the MBIs. In practice, many schemes that are being tried out are
actually combinations of CACs and MBIs thereby taking advantage of
the positive features of both approaches. For example, the sanctions
that are formulated under rule*making regimes may be market-
determined, as in the case of damages to be paid out by a mining firm
found responsible for polluting downstream*irrigated riceland farmers.
Another example is an environmental standard that is first specified to
reflect some measure of carrying capacity upon which to base the
amount of user right to market or bid out.
• FUTURE DIRECTIONS
The optimization models that were discussed in the previous
section could actually provide the initial conditions for specific
standards and targets to be explored at the level of a watershed
management unit. Modeling allows for information on various
dimensions of watershed management to be organized in a cohesive
manner. Additionally, the optimization models that incorporate valuation
of costs and benefits and stakeholder analysis could be used to
anticipate the potential trade-offs from alternative allocation schemes
and anticipate the sources of conflict.
Transforming various bio-physical data into monetary values, as is
done through economic valuation, enables the various stakeholders to
assess both the magnitude and the incidence of impacts -- i.e. who
bears the costs, who earns the benefits, and how much. Stakeholders
are thereby enabled to actively participate in decision-making: avenues
for conflict resolution become visible, such as payments that can be
made to make everybody better off when compared to the initial
conditions.56 JOURNAL OF PHILIPPINEDEVELOPMENT
The expertise that is needed for implementing optimization models
and economic valuation is available in the country. Transdisciplinary
effort is needed to rework these tools into watershed specific analysis
that is capable of generating practicable solutions to urgent problems.
What is required is for the specialists to go several steps further in
making their tools available and co-generating information to
proactively solve pressing problems.
At best, the application of such tools should reveal the directions
for resolving long-lived, unresolved debates, such as the commercial
logging ban, cutting ban in watershed reserves, the area to be allocated
for NIPAS, and the final forest line. At the same time local, site-specific
information should be generated in a consistent manner that will allow
for analysis of potential multiple uses, preferences of user groups, and
the costs and benefits associated with various choices.
The current organizational work being conducted for community-
based forest management paves the way for the previously dis-
advantaged groups of upland settlers and indigenous peoples to
actively participate in both the planning and use allocation stages of
watershed management. Additionally, the Internal Revenue Allocation
scheme should encourage local decision-makers to eventually develop
environmental monitoring and enforcement capability as well as create
higher demand for environmental and natural resource pricing at the
local level. A critical mass of practitioners with various specializations
is needed to respond to this challenge.
At the national level, what is urgent isfor the property rights regime
to be clarified, defined, and secured. Subsequently, capability for
arbitration needs to be developed at the DENR and the other agencies
that have been designated initial stewardship of specific watersheds.DELOSANGELES: WATERSHEDLAND USEALLOCATION 57
