Introduced by Senator JOSEPH VICTOR G. EJERCITO 
AN ACT TO PROMOTE THE PROTECTION, CONSERVATION AND REHABILITATION OF 
WATERSHEDS SUPPORTING THE NATIONAL IRRIGATION SYSTEMS (NIS) TO 
GUARANTEE CONTINUING SUPPLY OF WATER FOR AGRICULTURAL PRODUCTION 
AND TO INCREASE THE PRODUCTIVITY OF FARMERS TO SUSTAIN FOOD SELF-
SUFFICIENCY AND PROVIDING THE FUNDING THEREOF, 
EXPLANATORY NOTE 
WATER is essential to life and aJlliving things. It is undisputable that without water, 
there can be no life. To plants, water is critical for growth and good production. 
Insufficiency in water can lead to low yield, which could affect the food availability and 
sufficiency. 
The Philippines is an agricultural country with abundant river systems that can 
supply the water needs ofthe farming community, but the agricultural sector has suffered a 
continuous and immeasurable loss as drought is abundantly experienced throughout the 
country, and the devastation caused by flash floods and rising levels of waters due to 
excessive surface run off, which could no longer be contained by the river systems. What is 
worst is its recurrence every year without let up. The changing weather pattern is being 
attributed to global warming and climate change, which are simplest answer being given 
every time there is havoc brought about by el Nino and the increasing volume of rainfall. 
While it may be true that these circumstances are effects of global warming, there 
are also other man made actions that are contributory to the devastations. Man's 
insensitivity to his environment, the uncontroJled use of our forests and watersheds 
resources and the indiscriminate use of land resources that should have been reserved for 
forest use only were some of the other distinct numbers of contributory causes. 
"Deforestation and the large scale transformation of the original 
vegetation of the country's forest to non-forestry purposes, coupled with 
inappropriate land use practices, have in effect disrupted the 
hydrological conditions of watersheds. These have brought about to 
some extent, flash floods and prolonged drought Other adverse 
consequences are accelerated soil erosion, siltation of water bodies and 
reservoirs, and poor water quality. Sedimentation has likewise reduced 
the storage capacity of the country's major reservoirs. These situations 
caused considerable reduction in the productivit;y afforests, agricultural 
lands and fisheries and decreased returns from major investments in 
domestic, hydroelectric power generation and irrigation systems. "1 
No less than the Philippine Medium Term Development Plan (MTDP 2004-2010) 
indicates that major watersheds of the country are in a state of severe degradation which 
, Occasional Paper prepared by FMB-Watershed Division 


" 
resulted in reduction of capacity to supply water for irrigation, industrial and domestic uses 
and vital ecological services. 
Right now, watersheds provide the socio-economic base to a growing population 
through the utilization of watershed resources, which for many years has not been 
controlled, or necessary safeguards were not put in place. 
The continuing migration of the lowlanders for the uplands, which accounted to an 
estimate of 25 million Filipinos out of the 100 million of the entire country's populations or 
roughly 25%, and the encroachment in watershed forest reserves remained unabated. 
Having no viable economic opportunities in the lowland, these settlers became dependent 
on forest resources. To illustrate, the "kaingin" or the slash-and-burn method was resorted 
to by the migrant dwellers to be able to plant and increase the area of their tillage. The 
demand for agricultural land or the conversion of forestlands to non-forest use increased 
tremendously thereby exerting so much pressure on the watersheds forest reserves areas. 
Another contributory factor to the degradation of watershed forest reserves is the 
uncontrolled utilization of forest resources through mining and other similar mineral 
resource exploitation. 
Currently, the Philippines has 143 Watersheds supporting 165 National Irrigation 
Systems with a total area of 4.318.172 million hectares more or less, The water that comes 
from these watersheds areas and flows to the River Systems provides irrigation water to 
rice lands and other agricultural lands planted of different crops. There are only about 
483,820 hectares, more or less, being serviced by the 143 River Watersheds, but based on 
the NIA data, 868.509 hectares of agricultural land are being irrigated and roughly 368,000 
hectares of these have existing facilities but need restoration and rehabilitation. 
To date, the Philippines' area harvested with rice is very small compared with major 
rice producing countries in Asia. This is the major reason why we import rice. Although we 
say that we are an agricultural country, we do not have large land resource to produce our 
total rice requirement. The Philippines have 4.35 million hectares devoted to rice 
production in 2010 while 3.5 million hectares are irrigated and 1.35 million hectares are 
not irrigated nor irrigation facilities have been put in place to allow water to reach these 
rice fields.2 Nevertheless, instead of increasing the number of hectares that can access 
water to ensure bountiful rice harvest, there is now a continuous reduction in non-irrigated 
land, due to unabated conversion of irrigated and non-irrigated lands and the fact that 
there were not enough water flowing in the irrigation canals that feeds the rice fields. 
Another thing is the consistent irritation between the hydro-electric concessionaires and 
the National Irrigation Administration on how much volume of water can be allocated for 
irrigation purposes. People can live without electricity but they cannot possibly survive 
without food and water. 
The Philippine environment plays a very crucial role in supporting the country's 
sustainability and economic progress. And for these reasons, as an issue, which highly 
affects public interest, it is the obligation of the state, to secure and ensure that the 
environment is neither destroyed nor its beneficial effects be spoiled as well as, to protect 
and preserve the natural resources, to reap more benefits whilst negating the effects 
inevitably dealt to by nature. 
2 Philippine Rice Industry: Facts and Figures 


The former status of watersheds in the Philippines was characterized by abundant 
rainforest, which reached an estimated 17 million hectares in 1934.3 In 1969, after the 
completion of the first nationwide forest inventory, the forest cover had declined to 10.4 
million hectares. The second National Forest Inventory, which was done in 1988 revealed 
that forest cover further decreased to 6.461 million hectares. It is such a great loss that our 
forests cover declined vastly in span of almost half a century. In 2003, the country's forest 
cover was pegged at 7.168 million hectare4 or an increase of about 707 thousand hectare, 
which is mainly due to the much publicized reforestation program being initiated by the 
government and the public sector 
Out of the estimated 30 million hectares land area of the Philippines, 15,805,325 
hectares were classified as forestland and 14.194,675 million hectares were declared 
alienable and disposable and was subjected to private ownership. Of the 15,805,325 
hectares classified as forestland, only 3,270.146 million hectares were declared as 
Established Forest Reserves. Out of this, 1.561,128 million hectares has been proclaimed as 
watershed forest reserves. There are 143 proclaimed watershed forest reserves scattered 
all over the country, which cannot be touched by logging or mining.s 
It is for this reason that this bill is crafted to ensure the protection, conservation and 
rehabilitation of the watersheds supporting the national irrigation systems, thru an 
enactment of a law that will protect, preserve and rehabilitate these watersheds so we can 
be assured that these areas cannot be touched by man's insensitivity to nature and his 
environment.
