This article report is a condensed version of “The On-Site and Downstream Costs of Soil Erosion,” PIDS Technical Report 87-04 of the Upland Resource Policy Program. It estimates the economic costs arising from indiscriminate exploitation of the uplands. It also offers a practical methodology...

This paper presents an effort toward a better understanding of the potential impact of climate variability and change on the hydrology and water resources in the Philippines. Impacts of extreme events such as droughts are discussed. A preliminary study on the variability of inflow in relation to...

This article is prepared for the Upland Policy Conference on March 14, 1988. It discusses the degree of soil erosion in various watersheds based on classified descriptive parameters. It also proposes land use planning and allocation scheme.

Dealing with various topics such as watershed classification, computer simulation and modeling and computer application in watershed research, this paper assembles and summarizes technologies that are currently being used or have potential for application in the Philippines. This is in the hope...

Watershed conservation has always been the people’s cry. However, efforts in the past have not been enough to demonstrate this. This paper attempts to shed light on the importance of soil and water conservation measures popularly applied and adopted in the Philippine upland watershed setting....

Do the most promising policies to promote sustainable upland farming originate at the local or national level? Will coordination of local and national efforts produce better outcomes? This paper uses an optimization-simulation model of the Manupali watershed in the Philippines to investigate...

Well-defined property rights recognize the ownership of material and abstract things. The low enforcement of property rights for a certain resource may lead to its abuse. Hence, its application on watershed needs to be understood. This paper attempts to show the dualistic system of considering...

The valuation of resources found in the watershed area is important in assessing the impacts of changes in the watershed. While the change will have positive impacts which are short-term in nature, there are long-term environmental damages associated with economic benefits. This paper gives a...

This paper discusses the key issues and concerns regarding sustainable Philippine watershed management. Emphasis is made on the various requisites of a sustainable management with a focus on the critical roles of land use planning.

This paper summarizes a sampling of planning tools to provide ideas on how multiple objectives for watershed management may be tackled. It also explores the mechanisms for allocation with due emphasis on avenues for resolving conflicts. Future directions for subsequent work are suggested.
