Relationship of Forest and Watershed in the delivery of sustainable water supply

Forest is a major user of water Forest and agricultural land greatly affect water quality and flow.

Conversion of forest to other land use affect water quality. Land use alter natural hydrologic cycle (Barnes et al 2009)

- Removal of trees increases flood risk which resulted from induced water discharge. Recent hydrology research shows that forest removal or clear cutting increases downstream water yields or stream flow(Calder et al 2007) tree canopies reduce groundwater and stream flow, through

interception of precipitation and evaporation and transpiration from the foliage.

2. Able to get high water quality This is achieved through minimization of soil erosion on site, reduction of sediment in water bodies (wetlands, ponds, lakes, streams, rivers) and trapping or filtering of other water pollutants in the forest litter, particularly through the following mechanisms (Calder et al 2007).3. Improve water storage capacity, soil infiltration, can also influence the timing of water delivery

Page 6: Watershed management for sustainable water supply

Should we cut trees to get more water supply?

NO! Clearing forest may increase downstream water yield, but

it is only transitory, temporary and short-lived. It may also posed additional risk like flooding. Then if

forest regrow, the same problem will occur - water scarcity.

It is therefore unsustainable approach to achieve sustainable water supply. (Hydrologic Effects of a Changing Forest Landscape 2008)

Why watershed management?Watershed Management- the process of guiding and organizing land and other resource uses in a watershed to provide desired goods and services without adversely affecting soil, water and other natural resources (DENR Memo Circular No. 2008-05).Scientific research shows that watershed management increase water quality. Sustainable Development Goals (2015- 2030)Goal 6. Ensure availability and sustainable management of water and sanitation for all

6.1 by 2030, achieve universal and equitable access to safe and affordable drinking water for all

Page 8: Watershed management for sustainable water supply

Goal 15. Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss

15.2 by 2020, promote the implementation of sustainable management of all types of forests, halt deforestation, restore degraded forests, and increase afforestation and reforestation by x% globally.

Why do we need to invest in watershed management?

“The benefits from watersheds cannot be obtained for free. Watershed management has a financial cost, which society has to bear.”

– FAO-

Watershed management policy issues and concerns

Conflicting land-uses and practices within watershed areas- threatening activities includes firewood gathering,

charcoal making, selling of non-timber and timber products (Wunder, 2005) which many of the land users practiced in CPHPL (Malabarbas and Celeste, 2016). Inappropriate land classification and disposition of

watershed areas Continued encroachment and illegal occupancy Lack of economic incentives for watershed management

and protection.

Page 15: Watershed management for sustainable water supply

Lack of social and political considerations in implementing watershed management programs (Javier, 1999)

- Conflict of interest between upland (tenured migrants) and lowland settlers (Celeste, 2010) Limited adoption and institutionalization of the watershed

as a planning unit approach (Javier, 1999) Reduction of budget allocation for watershed management Lack of general watershed management plan

Approaches for watershed management

Non market based Landcare approach -

combination of conservation farming, agroforestry and natural resource management (Mercado and Sanchez)- refers to a group of people who are concerned about land degradation problems and interested in working together

Market based incentives

- Institutional and financial arrangements for collaborative watershed management - market-based mechanisms should be developed to recover the operation costs of watershed management though PES schemes

Payment for Environmental ServicesCosta Rica – pioneer in PES scheme

- sellers are private landowners who are contracted to implement conservation activities, such as reforestation and other forest management, in exchange for cash payments from buyers such as hydroelectric companies, among others, that have conservation interests.Northwestern Oregon - a local wastewater facility is paying upstream landowners to plant shade trees along the Tualatin River. Instead of installing refrigeration systems at two treatment plants—a $35 million expense with additional annual operating costs—the water utility is investing $6 million in direct landowner incentives to achieve the same water quality goals (USDA, 2007)

Page 22: Watershed management for sustainable water supply

Colombia – the PES scheme involved farmers in the Guabas River who negotiated with

upstream landowners to adopt improved land-use practices for the maintenance of dry-season river flows.User fees are collected from downstream farmers as payments for watershed protection services provided by the upstream farmers.Maasin Watershed - Rehabilitate the major source of domestic water for Iloilo City in the Visayas Region amid growing concern over its fast degradation (Salas)Balian Watershed (Non-cash payments)- Downstream residents mobilized themselves and negotiated with the landowners for the latter to plant trees and, in return, the former would protect these private lands from illegal encroachment through regular patrol and monitoring activities

Mt. Kanlaon Natural Park/La Tondeña Distillery Draw water inside the park - It engaged the local communities in reforestation and forest rehabilitation, and trained farmers in agro-forestry as payment for the watershed protection services the farmers provide.

REECS - PES program called the Bayad Kalikasan- to help promote sustainable management of Philippine

forests and coastal resources by undertaking PES-related research, producing bulletins and other information materials on PES, and by conducting workshops other forums
