Watershed

A complex idea can be conveyed with just a single still image, namely making it possible to absorb large amounts of data quickly.

MANAGEMENT And Watershed

1

“ Watershed? A watershed is a natural system whose boundary is determined on the ground by the highest points or ridgelines near or around a water body

The Philippines is facing unprecedented destruction and pollution of its natural

MILLION environment. Less than a MILLION hectares of tropical rain forests in the Philippines remain, compared to

29,999,991 29,999,990 HECTARES in 1950

At least one billion cubic meters of prime topsoil are eroded every year. 30% of the rivers have died.

There has been a tremendous loss of biodiversity on land and in

waters and thus a drastic reduction in agricultural and marine productivity.

Factors Affecting

Watersheds • Human activities such as upland agriculture, land conversions, destructive mining, and illegal logging, among others, have caused the degradation of watersheds in Southeast Asia, particularly in the Philippines.

The Role of the Philippine Government •

Republic Act 7586 otherwise known as the National Integrated Protected Areas System (NIPAS) Act of 1992 provides the legal framework for the establishment and management of protected areas in the Philippines. The Law defines protected areas as the identified portions of land and/or water set aside by reason of their unique physical and biological significance, managed to enhance biological diversity and protected against destructive human exploration.

THE THE CONSTITUTION CONSTITUTION OF OF THE THE REPUBLIC OF THE

PHILIPPINES Article 11 of the Constitution maintains that the State shall protect and advance the right of the people to a balanced and healthful ecology in accordance with the rhythm and harmony of nature.

CHALLENGES IN WATERSHED WATERSHED MANAGEMENT MANAGEMENT & & GOVERNANCE

• For one, watershed management is multi-objective. • Watersheds are composed of a conglomeration of many different ecosystems. Want big impact?

Use big image.

• Watersheds also encompass many different local government units (LGUs), settlements, and natural ecosystems, which make the decision-making process a problem.

WATERSHED WATERSHED MANAGEMENT MANAGEMENT IN IN CLIMATE CLIMATE CHANG CHANGE E Want big impact?

Use big image.

Thus, to have effective watershed management strategies, an

integrated watershed management framework must be developed. The framework needs to consider the transboundary nature of physical and human systems within a watershed, thus the legal and institutional arrangements should

go beyond the traditional geopolitical boundaries. 12

Ecological Sustainability

GUIDING PRINCIPLES FOR IMPROVED WATERSHED MANAGEMENT

•

The technologies and production processes involved in using and developing a watershed’s natural resources should not have adverse environmental effects.

Social and Cultural Sustainability •

The use and development of the watershed’s resources should be compatible with the culture and values of the people affected by it and should strengthen community identity.

GUIDING PRINCIPLES FOR IMPROVED WATERSHED MANAGEMENT

Economic Sustainability •

Resources must be used and managed in an economically efficient manner and must benefit the greatest number of people.

Institutional Sustainability •

Community-based organizations, NGOs, LGUs, and national agencies involved in watershed management planning, implementation, and monitoring should have the financial and human resources to sustain the delivery of services.
