Are we biting the hand that feeds us? Knowing the Filipino farmer—their struggles and aspirations
by Lois Mauri Anne L. Liwanag
Bachelor of Science in Development Communication
Visayas State University
Waking up in the morning greeted by the inviting smell of freshly cooked rice for breakfast, drinking a bottle of cold buko juice on a warm summer afternoon, or coming home to a piping hot serving of sinigang loaded with fresh vegetables for dinner—these are only some of the many best things in life that most privileged Filipinos take for granted.
Ironically enough, the persons who worked hard for the food served on dining tables are the very ones who are unable to eat a proper meal three times a day.
Knowing the Filipino farmer
According to Asterio Saliot, the former director of the Department of Agriculture-Agricultural Training Institute (DA-ATI), the average age of a Filipino farmworker is 57, with an average level of education of grade five, working on an average of a 1.5-hectare farm.
Their job is not limited to planting vegetables or fiber. They engage in agriculture which involves cultivating field or specialty crops, handling orchards or vineyards, and raising poultry or other livestock for food, fiber, and raw materials. The crops that they mainly focus on cultivating in the country include rice, corn, coconut, sugarcane, bananas, pineapple, coffee, mangoes, tobacco, and abaca.
The said farmer receives less than half of the wage an average Filipino worker earns; they only produce one-sixth of the value of output produced by a worker in the industry. With lower wages and even much lower productivity, farmworkers make up two of every three of the country’s working poor (Habito, 2018).
Farmers in the Philippines are generally poor and marginalized, unlike the ones in nations like the United States, China, Japan, and Thailand, where they are given more credit, resources, and most especially—respect.
Struggles
Despite being in an agricultural country, Filipino farmers remain as one of the poorest sectors in the Philippines, with the highest poverty incidence in 2015 at 34.3 percent, according to the Philippine Statistics Authority (PSA). This ironic fact has been the reality of the people who feed the population and keep the economy alive.
At present, some farmers are said to believe that there is more money with education. In hopes of continuing under the agricultural sector, they send their young ones to school in order to gain more knowledge and skills. Unfortunately, the younger generations turn away from agriculture with their favor leaning towards livelihoods far from the hardship of being under the sun or soaking in dirt and mud.
On the other hand, there are also some farmers who let their children help in the field as soon as they start to learn how to lift or till. As a result, there is a multitude of Filipino farmworkers who are not aware of the illegal or harmful farming practices they do because of inadequate proper education. They perform kaingin or slash-and-burn and apply excessive inorganic pesticides and fertilizers, thinking that these are the normal things to do since they have already grown used to it or they have already been doing this ever since.
Apart from this, some of the common problems of the Filipino farmer that causes them to experience poverty, unproductivity, and marginalization are: 1) insufficient government support, 2) inequality in land distribution, 3) unfair trade practices, 4) increasing population growth, 5) natural calamities, 6) unpredictable market demand, and 7) armed conflicts specifically in Mindanao.
Aspirations
The opportunity to interview some farmers and other agricultural workers arose at the Farmers’ and Fisherfolks’ Day held last April 27, 2019, as a part of the celebration of Visayas State University’s Anniversary.
Several of them were asked one common question: Ano ang kaunlaran para sayo? [What is development for you?]
The said interview was supposedly a requirement for a project in a Development Communication course. However, it unexpectedly reflected some of the farmworkers’ vision and aspirations:
“Kaunlaran? Syempre pagsaka o pagtanim sa sariling lupa, sa Pilipinas.”
[Development? Of course farming or planting on one’s land, in the Philippines.]
“’Yung hindi na natin kailangang humingi ng pananim ng ibang bansa.”
[When we no longer have to ask for the crops of other countries.]
“Para sa’kin, maunlad na siguro kung hindi na kailangan gumamit ng fertilizer at pesticide sa pagtanim.”
[For me, it would have been better if there was no need to use fertilizer and pesticide for planting.]
“Mapagtapos (ng pag-aaral) mga anak ko at matulungan pa mga kapatid ko.”
[To make my children graduate (from school) and help my siblings more.]
Contemplating on these answers, it is quite evident that farmers desire simple yet impactful things. Amidst the countless criticisms and suggestions from politicians, academicians, and even citizens in order to improve the country’s agricultural sector and the farmers’ way of living—the answer seems so light and easy in the eyes of these hardworking people. They simply need and want a better quality of life for themselves, for their families, and if possible, for the whole nation.
Receiving enough funding and support from the government, legally acquiring the land originally deserved, selling hard-earned products at a just and reasonable price, and experiencing a more proper and formal education—these are only some of the many other aspirations in life that most unprivileged Filipino farmers yearn for every single day.
Ironically enough, the persons who have the capability to make these dreams a reality are the very ones who are causing the farmers’ adversity.

What does it take to be an agronomist?
By Dr. Jose L. Bacusmo, Past President,
Visayas State University
---------------------------------
What does it take to be an agronomist and what lies ahead of him or her?
Here are important figures for us to consider:
Here are important figures for us to consider:
· a) In 2017, the total
paddy rice output of the Philippines met 93% of the country's annual
requirement. The population consumed 11.7 million tons of rice. (usual shortage
of 10% and brown rice/rice bran solution).
· b) In 2016, for every 17
births per 1000 population there were 6 deaths per 1000 population. Every minute, 2.8
Filipinos are born. Every 10 or 11 minutes, we need one new classroom and down
the road each of these kids will consume 120 kg of rice per year. (why is Philippine
presidency such a contested and contentious position?)
(“ang ginoo pito ra
kaadlaw nagbuhat ug yuta pero ang tawo walay hunong himo ug bata”-Gov. RE
Lerias)
· c) All of the scenarios of
future climate change (CC) point to increase the estimates of the number of
people at risk from hunger. (ascribing everything to climate change)
This country is therefore in dire need
of professionals who study plants and work for increasing their production in
an economical and environmentally sustainable fashion. Mind you, it is not only
this country, but the whole world. Who are these professionals?
Used to be in the 1970’s and earlier,
there was not much specialization. When it was plant, agronomists took care of
it. Thus, an agronomist takes care of management: soil, pest, and other growth
and production issues in the field. I remember that there were only agronomy,
animal science, agricultural education, and home science as major fields on this
campus. (lots of fieldwork/learning by working, Agric was looked down).
Later, when Visayas Agricultural College
(VAC) became a state college (ViSCA), other specializations were introduced
such as arts and letters, ag. engineering, ag. economics, ag. chemistry, plant
protection, plant breeding, forestry, vet. medicine grew out of animal science,
ag. extension and dev. communication grew out of ag. education, food tech grew
out of home science, and horticulture grew out of agronomy and, soil science
was added to the agronomy department. Specializations are important for us to grow.
In the latter years of my term as president
of this university, we had to “handle with care” a formal divorce of agronomy
and soil science. (jurisdiction and
property distribution were quite tricky and sensitive to handle but they can’t
go back living together again).
All these specializations somehow delimit the scope of work agronomists are expected to deliver professionally. However, specialization did not and will not limit farmers’ expectations from an agronomist and other agriculture-related graduates from this university. In our national context where an agronomist most likely finds himself/herself engaging with farmers alone in the field, an agronomist is also expected to be a good soil scientist, farm economist, horticulturist, plant breeder, communicator and even good in animal production, aquaculture and forestry or NRM to name some. To farmers, an agronomist is an “agriculturist”- an embodiment of expert. (McCoy and Ormoc rice farmers, Roy and cassava growers)

What
does this tell you?
Do not limit yourself to knowing only
field crops and cultural management practices. Endeavor to know and master beyond
crop science. I recently analyzed the CHED Memorandum Order (CMO) that governs
offering of agriculture and observed that the prescribed curriculum provides
graduates the sciences needed for one to become a good agriculturist (but good
is not enough). However, the CMO doesn’t preclude us from adding additional
fundamental and major courses especially that now, some of the general education
courses have been downloaded to senior high.
I will not interfere in the plans of this
department, but I personally still subscribe to a 4-year BSA major in Agronomy curriculum
rather than the 12+3. With the growing demand for climate SMART and precision
agriculture, agriculturists need more mapping techniques, advanced soil study
techniques, and even more understanding in biotechnology and IT. (possible from
cross enrolment in the fourth year)
Furthermore, the CMO does not preclude
our agronomy professors to deliver the course in a more advanced and exciting
manner that students will endeavor to learn as much as possible in the course
and not endeavor to end their suffering as soon as possible from taking their
courses. This can only happen if professors in this department will engage in
research/driven by discovery, extension work, and actual farming. (farming
lessons on seeds and weeding)
Specialization is usually overcome by
collaboration or partnership but, it will be hard for anyone to
collaborate/partner with someone who doesn’t have anything (absolute
provision). If you don’t have anything other disciplines can offer, without your
partners/collaborators, you will be paralyzed/inutile and unable. A person is
appreciated and recognized usually when he can deliver more than what is
expected of him. (basketball experience)
So, to faculty members and students, make
BSA major in agronomy broad and exciting by learning beyond your coursework and
collaborating with other specialists. For example, it will not be bad if some
of you do research involving drones and high spectral cameras for field
observation and management delivery. It will be exciting to see our agronomy
students study how to use GPS and make or handle GIS maps as tractors are now
equipped with GPS, and future tractors will be dominated with robotics. It will
be great to see our agronomy students use plant or crop physiology study sensors,
do genetic modification in their thesis or deal with soil problems as it
affects field crops. Clearly for this to happen, there is a need for different
specializations to relax, weaken, and render more permeable the boundaries of
various specializations of agriculture in this university and allow greater
collaboration.
So,
what’s the future of agronomists?
Let me say that the future of this
country and this world depends on the agronomists. Agriculture is the backbone
of this country and we need to feed and clothe an ever-growing population.
Agronomists are simply crucial to pulling off the job.
However, they should not be agronomists
as usual. There is a saying that “a solution should measure up to the problem”.
The problem of food and resources in this country has become more difficult and
complex than the new breed of agronomists should be armed with complex
knowledge and skills. With appropriate knowledge and skills, an agronomist will
be potent and can go “places”. Short of this, an agronomist is doomed to be
unexciting and lame.

Refocusing Agriculture in the Philippines
Refocusing Agriculture: Excerpt from my Convocation Speech at the 45th Founding
Anniversary of Visayas State University (VSU)-Alangalang Campus, Leyte,
Philippines on 09 Sept 2016.
By V.B. Asio
Your theme “Agrivolution: refocusing farming for
food and nutrition security” is very timely and very relevant.
When I was an agriculture student in ViSCA in 1980,
the agriculture battle cry was: we need to increase crop yield by increasing
the yield per unit area and by cultivating new lands because of the rapidly increasing
population. The population of the country at the time was only 48 million. The hot
research topic was farming system, which slowly became cropping system, then
sustainable agriculture or ecological farming, and now organic agriculture. If
you examine these farming strategies, they are closely related. But the last,
which is organic agriculture, has become very narrow in scope and very
impractical in many aspects.
But where are we now?
Now more than 30 years have passed, with a
staggering country’s population of more than 100 million, we still have the
same battle cry: to increase food
production by increasing yield per unit area and by opening new lands. This
time though, there are a lot more complications. The problem of increasing food
production has become more urgent, and very problematic. Let me cite some
reasons:
1. The
gap between population increase and food production has greatly widened. Our
population has more than doubled but crop yield has not doubled despite the
availability of new high yielding varieties, fertilizers, and pesticides. For
example, the average rice yield in 1980 was 2.3 tons/ha. Now it is only 3.8
tons/ha. What is aggravating the problem is that production cost has greatly
increased, and the area of our agricultural lands has decreased.
Many of the new high yielding varieties which showed
great potential in the experimental stations have failed to show their yield
potential in the actual world-- in farmers’ fields. According to Dr. Francisco
of Philrice in an undated paper, the yield gap ranges from 2 t/ha in the wet
season, to 3.9t/ha in the dry season. This also partly explains why we cannot
find our new high yielding varieties (say, of sweetpotato) in farmers’ farms in
Leyte and Samar.
2. There
is increasing soil degradation due to destructive farming practices, resulting
in a decline in soil fertility. This is coupled with increasing incidence of
pests and diseases. The latter triggers the farmers to over-apply pesticides. In our on-going ACIAR-funded soil research,
vegetable farmers in the Visayas and some parts of Mindanao just apply any
amount of fertilizers without a scientific or logical basis. Worse, they
over-apply a cocktail of pesticides, 2-3 times a week, endangering the health
of the consumers.
3. As if
to make the matter more difficult for the next generation, the widespread soil
degradation is accompanied by the shrinking of our prime agricultural lands
because of urbanization. Urbanization is eating fast our rice lands. In many
parts of the country, you would see former productive rice lands have become
subdivisions, factory sites and shopping malls.
4. Climate
change has entered the picture. It has changed the rainfall pattern, temperature
fluctuations, and occurrence of typhoons, floods, and drought. Crops are now
subject to extreme weather conditions. In short, we are in more challenging and
exciting agriculture.
5. As a
result of the over-application of farm inputs, there is also a degradation of
the environment. Soil, water, and air pollution are very serious in many places.
6. This
has led to the rise of the organic agriculture movement. The Philippine
government has enacted the Organic Agriculture Act of 2010. But we know that
organic agriculture cannot produce the amount of food required to feed the fast-rising population of the country. Organic agriculture cannot feed our more than
100 million population.
So, we are now facing a dilemma: protect the environment even if the food
production is low, or continue the environmentally damaging practices but with higher food production. This is like the choice between the ocean and the
deep blue sea.
7. The
Genetically Modified Organisms (GMO) technology hold great promise for some
crops, but are we sure that they are safe? The debate is raging in the
international scientific community. Time will tell if GMO crops are really safe
for our health and to the environment.
8. Despite
the more than 40 years of designing of agricultural implements, most of our
farmers are still practicing manual labor due to a lot of reasons. Have we
really looked into why the majority of our farmers are not using modern farm
implements until now?
9. What
threatens further our agriculture is the decreasing interest in farming among
our young generation. It seems everybody wants a happy and easy life. Interest
in agricultural science has continued to decline as reflected by the general the decline in enrollment in universities and colleges around the country
(fortunately, our enrolment in agricultural sciences at the main campus has
continued to increase in the last five years).
10. The
mainstream media are partly to blame. Just observe what kind of TV programs are
created and promoted. To cite an example, beauty contests are very popular
because of the intense media campaign. No wonder many young girls dream to be a
beauty queen instead of becoming scientists. The media have failed to create
awareness among the youth about the importance of agriculture or about science.
And of course, our government institutions too. Much of the blame should go to
them.
What should we do? How can we refocus farming or
agriculture?
The problem is so serious and so complex. It needs
the active participation of all sectors involved. As an academician, I will
just focus on the things that we can do in the academe.
1. There
is a need for retooling of those involved in teaching students agriculture.
Agricultural science now is different in many aspects from that 30 years ago.
2. We
need to revise and improve our curricula and the courses we are offering. The recent move by CHED is to change the agricultural science curriculum (i.e. BSA) by adding more entrepreneurship courses. Is this the solution to the problem in our agriculture? To me it is a big NO. It is like changing the wrong tire. If it is true that more entrepreneurship courses in our BSA curriculum will produce more agri entrepreneurs, then why is it that graduates of BS Agribusiness and other business courses have not accomplished this. On the contrary, this will greatly weaken agricultural science in the country.
3. We
need to change our strategy in promoting agriculture. If we still project
agriculture using the image of a farmer with the plow and the carabao, we will
not gain bright young students to agricultural science.
4. There
is a need for more involvement of our students in OJT in successful and
progressive farms.
5. We
need more reliable data on the effects of fertilizers on crop yield. In the
last decade, everywhere, there has been sprouting of all kinds of organic fertilizers whose efficacy has not been scientifically verified. Proponents just cite anecdotal evidence to promote their products. This has led to erosion in people's confidence in organic fertilizers.
6. We
need to change our strategy in extension. We need to educate more our farmers.
How? It is for all of us to think about.
Before I end my talk let me quote Masanobu Fukuoka,
a Japanese farmer and philosopher. He said:
“The ultimate
goal of farming is not the growing of crops, but the cultivation and perfection
of human beings.”
Thank you for your kind attention. Happy 45th
Anniversary to VSU-Alangalang!

Organic Fertilizers, Organic Plant Growth Regulator, and Organic Plant Supplement as defined in the new Philippine National Standard for Organic Fertilizer
The new Philippine National Standard (PNS) for
Organic Fertilizer was published in 2013 by the Bureau of Agriculture and
Fisheries Product Standards (BAFPS) of the Department of Agriculture (PNS/BAFPS
40:2013).
According to this new PNS, Organic Fertilizer is “any
product in solid or liquid form, of plant (except by-products from petroleum
industries) or animal origin that has undergone substantial decomposition that
can supply available nutrients to plants with a total Nitrogen (N), Phosphorus
(P) and Potassium (K) of five to seven percent (5-7%). This may be enriched by
microbial inoculants and naturally occurring minerals but no chemical or
inorganic fertilizer material has been added to the finished product to affect
the nutrient content.”
Organic Plant Growth Regulator/Promoter is “any
compound of organic origin, in liquid or solid form, which in low concentration
promotes or modifies physiological process in plants.”
Organic Plant Supplement is “any compound of
organic origin in liquid or solid form which in low concentration promotes or
modifies physiological processes in plants. Total NPK is not lower than 0.5%
and not more than 2.5% (0.5-2.5%) and may contain beneficial microorganisms,
micronutrients and plant growth regulators. These plant supplements include,
but are not limited to: FPJ (Fermented Plant Juice), FFJ (Fermented Fruit Juice),
FAA (Fish Amino Acid), FE (Fish Emulsion), Seaweed Extracts, Vermi Tea, Compost
Tea and the like.”
The Technical Working Group which prepared the new/revised
PNS was composed of: Dr. Leo P. Caneda, Executive Director, BAFPS (Chair) and
the following members: Dr. N.B. Inciong (Professional Regulation Commission), Dr.
E.P. Paningbatan Jr (Univ Philippines Los Banos), Dr. E.S. Paterno (UPLB), Dr. P.B.
Sanchez (UPLB), Dr. V.C. Cuevas (UPLB), Dr. G.V. Pangga (UPLB), Dr. B.M. Calub

Response of Abaca (Musa textilis Née) to shade, irrigation and fertilization
![]() |
| Abaca plants |
Abaca (Musa textilis Née), a relative of the edible banana (Musa acuminata and Musa balbisiana), is a native to the Philippines. It is grown primarily for its fibers which are utilized by the pulp, cordage and fiber craft industries. Studies have shown that the specific tensile strength of abaca fiber is comparable to or even higher than that of fiberglass (Bledzki et al., 2007;Sinon, 2008).
Dr. Marlito Bande and co-workers, in a paper to be published in the international journal Industrial Crops and Products 42:70– 77, reported on the optimum light, nutrient and water requirements of abaca to attain optimum yield. They also discussed how these parameters affect fiber recovery and fiber quality under field conditions.
They showed that abaca planted under 50% shade had significantly (p < 0.01) higher fiber yield than those planted under the other shade/light treatments (30% and 40% of full sunlight using polypropylene shade nets) since the plants pseudostem under such treatment were longer, bigger and heavier.They revealed that the combination of irrigation and fertilization further enhanced fiber yield to as much as 41% but this was not enough to offset the effects of shade on the performance of the plant which significantly (p < 0.01) increased fiber yield to as much as 165%. Shade and irrigation–fertilizer application had no significant effect on fiber fineness and tensile strength.
They concluded that 50% shade is the optimum requirement of abaca to achieve an optimum machine stripped fiber yield of 135.04± 4.31 g/plant without affecting fiber quality for industrial purposes.
The study which was conducted in Ormoc, Leyte, Philippines was funded by the German Research Foundation (DFG).

A comparison of organic and conventional farming
The Council for Agricultural Science and Technology (CAST) in the USA, assembled in 1980 a high-powered Task Force composed of 24 scientists (chaired by S.R. Aldrich) with expertise in agricultural economics, agronomy, animal science, dairy science, entomology, food science, horticulture, soil science, veterinary medicine and others to look into the similarities and differences between organic and conventional farming. The Task Force report, which remains very relevant to the current debate surrounding organic and conventional agriculture, was officially published as CAST Report No. 84 "Organic and Conventional Farming Compared" in October 1980.
Some of the interesting highlights of the report are:
1. Conventional and organic farming have much in common. They differ principally in the use of modern chemical technology. Conventional farmers use commercial inputs (fertilizers, pesticides, animal feed additives) to increase productivity while organic farmers prefer to use natural resources.
2. Both conventional and organic farmers use various mechanical, biological, and other means to control pests. Conventional farmers use synthetic pesticides but organic farmers prefer to avoid them.
3. Conventional farmers extensively use nutritional supplements in animal feeds, hormonally active substances, and drugs. These substances are generally unacceptable to organic farmers.
4. The terms "natural" and "organic" are often used interchangeably in organic farming. But in science, organic refers to carbon compounds. Many such compounds occur in nature and many are synthesized in laboratories and factories. Likewise, many inorganic or nonorganic compounds occur naturally. Hence, natural compounds are not necessarily organic, and organic compounds are not necessarily natural.
5. Urea is a natural organic waste product of human and animal metabolism. It is present in animal and human excreta and is therefore accepted as a natural and nonartificial nitrogen source in organic farming. However, the urea that is synthesized in factories which is chemically identical to the urea produced by human and animal metabolism (used as fertilizer in conventional farming), is not acceptable in organic farming. This is one of the inconsistencies in organic agriculture.
6. The urea produced by animals (present in excreta) or by factories (in commercial fertilizers) is transformed in the soil into ammonium and nitrate ions, the important forms of nitrogen taken up by plants. Both ions are inorganic, not organic. Therefore, in scientific terminology, the organically grown food produced with urea derived from animals is actually "inorganically grown."
7. The "organic foods" produced by organic farming are composed of chemicals. Most foods contain many chemicals, and most of these are organic chemicals, whether the foods are produced by conventional farming or organic farming.
