Globalization Eroding Cordillera Peoples Steadfast Watch Over Environment Michael A. Bengwayan High in the mountains comfortably nestled upon the lofty heights of the Cordillera mountain ranges, tribes hold the key to information that can unlock a model of conservation. For them it is not about trees, animals, and plants; it is a way of life. It is a life that provides a playing and training ground for their children, and as they nurture the land, they are nurtured by it. It is their wealth. The indigenous Igorot (a collective name for the tribes of the Cordillera) practice the development and management of centuries-old forests, rice land, home gardens, watersheds where forest denizens and rivers and springs abound. But these are becoming a thing of the past. Like most anyone else on earth, globalization is slowly but surely creeping into the traditions of the Igorots, endangering its food security, bond with the land and resources and laying to waste what has been protected for centuries. Mining, commercial agriculture, pesticides and chemicals, destructive farming practices, logging and anything tied with cold cash are greed are laying havoc over the land. For instance, the age old tayans here, knowns as lakon in western Mountain Province as well as the muyung and pinugos — woodlots of the Ifugaos are on their way to fading out. The indigenous technology used in he tfamed Banaue rice terraces, and many more indigenous knowhow, are equally threatened. The terraces, dates back some 2,000 years ago. Conservation is not new to the Igorot families of the Philippines, especially the Ifugaos. A system of blood ties, collective responsibility, heredity, litigation, and indemnity provides the bond that keeps the people together. However, many laws have been passed that undermine the life, caretakership, and knowledge of the Igorot as a whole, through disinheriting them: first through Spanish colonization, then American, and in modern times, the Filipino government. Two thousand years ago, the Ifugao carved out, by hand, terraces creating farms from the mountain sides, until this day, a practice that has become a part of their daily lives. They do not consider themselves as owners of the land, but as caretakers. As caretakers they have a social responsibility for the muyung (woodlots) thatare above the rice terraces. If someone wants access to the resources, he or she has to ask permission; when permission is granted, the person who has benefited from the resources contributes toward the environmental balance of the muyung by clearing an area of weeds before leaving. The exchange is one of obligation and responsibility, not money for the use of this man-made landscape of alternating woodlots and rice paddies. This reciprocity is extended to other aspects of the lives of the Ifugao. In the National Schools Maintenance Week, May 2006, Ifugao parents all contributed their time and resources in the repair of their schools. Roofs were painted, footpaths fixed, ceiling boards replaced, furniture repainted, gardens were cleaned, broken windows replaced, and other damages fixed. Muyung/Pinugos Muyungs are noteworthy features of Ifugao families. Muyungs are woodlots that are privately owned by way of inheritance, although there are also communally owned muyungs. Most often, it is the youngest daughter who inherits the muyung. This practice is believed best because the older members of the family are present to help in the conservation of the muyung until the youngest is of age and can decide what she will do to manage the muyung. And so the customary laws were set by the elders a long time ago that in case the daughter does not marry, she will have a place to get her timber, fuel, and other house needs. Muyungs are seldom sold, except in dire financial need. xample of a Muyung – Indigenous Ifugao natural resource management The Ifugao families know that with the development, preservation, and management of a muyung comes water to irrigate rice fields and vegetable plots, food for the table, timber for shelter, medicine for the sick, firewood for cooking, and natural resources for customary and cultural practices. The famed Banaue rice terraces are dependent on the muyungs for irrigation. Below all muyungs are rice terraces known as kaingin or habal — swidden farms, which are temporary plots of land that are maintained by cutting back and burning off the vegetative cover. This system allows water from the muyung springs and brooks to irrigate rice fields and prevents topsoil erosion. Cutting or harvesting of the trees is done strictly on a selective basis, as widescale cutting is not allowed. The elders of families and clans are the ones who are authorized to choose and mark the trees that can be cut. Men do the cutting, but children help cut branches of fallen trees, from which they clean off the twigs to bring home as firewood. Planting is done by all family or clan members. Family members, including children, regularly weed and prune their muyungs as a part of the regular upkeep, but most of the work is done by the women. Violations of customary laws, and related regulations call for strict penalties and fines. Today, some parts of the muyungs are being turned into small areas for vegetable production because many families are in need ofcash. Many fruit tress are also being integrated to provide family income. In recent years the mining industry has threatened the local environment and the traditional ways. Exacting might over right, the mining contractors, an interfaith stance calls out: “That Creation itself will be liberated from its bondage to decay and brought into the glorious freedom of the children of God.” (Romans 8:21) [ And the earth We have spread it forth; and made in it firm mountains and caused to grow in it of every suitable thing. And We have made in it means of subsistence for you and for him for whom you are not the suppliers.] (Al Hijr 15:19–20) “(Land is) a gift from Magbabaya to a people he has put in a place in order to develop and guard Creation. As a divine gift, it could not be owned by anyone for one cannot own that which gives life.” (Dibabawon Tribe) The UNDP considers the agricultural technology of the Ifugao as a fine model that should be replicated elsewhere, and no local conservation initiative could afford to ignore it. However, just as many of the features are not apparent to the unaware observer, so too is the system of belief, that gave birth to the Ifugao conservation practices. michaelbengwayan1.jpg Michael A.

CORDILLERA ECOLOGICAL CENTER

 

The Cordillera Ecological Centre, is an Echoing Green Foundation, New York City. USA winning project. The MISSION of CEC is “To Plant Gasoline Trees to Help Offset Carbon Dioxide Emission, particularly Pittosporum resineferum Petroleum tree, and nitrogen-fixing trees (NFTs) to fight poverty and environmental decay through social change.”

To do this, it raises and trains rural communities to plant petroleum trees and NFTs as it provides appropriate information that enables common people to implement and concretize culturally acceptable, ecologically sustainable, gender sensitive, and economically viable activities that promote equitable use, management, conservation and development of natural resources. CEC focuses on reducing CO2 emission, agroecology or nature farming, reducing soil erosion and conservation and indigenous knowledge because the three are interrelated and interdependent.
WHY IS CEC RELEVANT? Climate change is upon us and global warming is worsening basically due to increasing GHG like CO2, methane and sulphur dioxide. CEC believes that education and information are tools for knowledge and can empower marginalized and disenfranchised people to directly reduce the problem and be directly dependent on local natural resources to address the climate change issues. It adheres that empowerment is essential but is not the only means to achieve meaningful reforms. It also believes that, for a development agenda to be successful, especially a conservation or agricultural program, the rights and privileges of indigenous peoples should be recognized and protected without pre-conditions under recognized international, national, local and most important, traditional laws and statutes. As most local people are affected by climate change, biodiversity conservation and agriculturally-related programs, CEC opines that indigenous knowledge and traditional resource rights are important factors that should be considered because both immensely contribute to the formation of conventional and scientific know-how and environmental justice.
WHAT IT DOES? By providing proper education, skills and training, CEC helps in CARBON DIOXIDE SEQUESTRATION, , lessen soil erosion, O2 REPLENISHMENT, bridge the poverty gap and helps ensure biodiversity conservation and food security. CEC provides skills training and technical assistance, livelihood development, technological and educational support. To achieve its MISSION, CEC has two goals: educate as well as implement skills enhancement on appropriate conservation and use of Pittosporum resineferum tree and NFTs, agroecology and sustainable farming. It also promotes culturally acceptable tree technologies that help local peoples develop, manage, use, benefit from and conserve natural resources better, and; educate, inform, stimulate policy-advocacy and arouse public interest and debate among leaders, scientists, researchers, students, development workers and policy-makers.

Community Seedbanks Create Tomorrow's Biodiversity Edens By Michael A. Bengwayan

 

Community Seedbanks Create Tomorrow's Biodiversity Edens

By Michael A. Bengwayan

Contrary to scientific perception that high-tech genebanks hold the future of flora in its vaults, tomorrow's plants for food and medicine are in jars in many obscure rural villages globally, awaiting their turn to be planted for humanity's needs.

Expensive genebanks especially those of international research agencies under the Rome-based Consultative Group on International Agricultural Research (CGIAR) and private profit-oriented companies hold most seeds of the world.

CGIAR members include 15 members namely: International Rice Research Institute (IRRI) in the Philippines, International Potato Center (CIP) in Peru, International Maize and Wheat Improvement Center in Mexico, International Crops Research for Semi-arid Tropics (ICRISAT) in India, International Center for Tropical Agriculture (CIAT) in Colombia, Africa Rice Center in Benin, Biodiversity International in Italy, Center for International Forestry Research (CIFOR) in Indonesia, International Center for Agricultural Research in the Dry Areas (ICARDA) in Lebanon, International Food Policy Research Institute (IFPRI) in the US, International Institute of Tropical Agriculture (IITA) in Nigeria, World Agroforestry Center in Kenya, International Livestock Research Institute (ILRI) in Kenya, International Water Management Institute (IWMI) in Sri Lanka, and; International Center for Living Aquatic Resources Management, (ICLARM) in Malaysia.

The top ten giant private seed companies include Monsanto, Shell, DuPont, Syngenta, Groupe Limagrain, Bayer, Takii, Sakata, Land O Lakes, KWS AG, and DLF Trifolium.

As climate change worsens and threatens flora especially food crops of millions of people today and worse, the future, scientists are scrambling to collect and save today's seeds, many of which are nearing extinction.

Seeds in Farmers Hands

But this is easier said than done. Most farmers no longer want to share their seeds to the scientific community. Farmers' distrust and suspicion of scientists' motives remain fresh after years of biopiracy that saw thousands of traditional food varieties lost as genetically-tinkered varieties took over farms in Asia, Africa and South America.

When researchers usually from transnational companies take, use and profit from biological resources and traditional knowledge without permission, or exploit the cultures from less affluent countries or marginalised people, it is called biopiracy.

“It is not surprising,” Chief agriculturist Pandey Napradeyah of the Bharatiyah Agro- Industrial Foundation (BAIF), peoples' rural devevelopment group of scientists in India said, “for too long, local rice, other cereals, vegetables and spices were lost through the false promises of the Green Revolution, what did not disappear due to the onslaught of laboratory-bred varieties suffered fom the effects of dangerous chemicals,”he continued. The author visited the BAIF headquarters in Pune, Maharahstra.

Traditional crop biodiversity have, for centuries, been selected by farmers for the seeds' unique suitability to local growing conditions such that scientists claim they are more likely to adapt to changing climatic conditions.

The scientific community intends to put its hands on some of these, the Global Crop Diversity Trust recently approved millions of US dollars to fund the global seed collection effort.

Thousands of local and heirloom food crop varieties are in farmers' hands mostly treasured through home and community seedbanks.

Community- Based Seedbanking

Home and community-based seedbanks are community-level seed-saving initiatives that have existed in many countries around the world since farming was discovered by man. Broadly speaking, community seed banks are local, mostly informal institutions whose core function is that of collectively maintaining seeds for local use

Napradeyah elaborates, “they are usually part of farmers’ informal seed systems, in which the various stages of seed management—selection, conservation, exchange and improvement take place, the drivers underlying their establishment, evolution and sustainability vary considerably. ostly set up following a famine, drought or flood and the accompanying loss of local seed supplies”, he added.

The UN Food and Agriculture Organization’s (UNFAO) Second Report on the State of the World’s Plant Genetic Resources for Food and Agriculture acknowledges the relevance of community seedbanks, saying “ these act as platforms of community-based management of agricultural biodiversity that can ensure effective implementation of farmers’ rights through the recognition of local knowledge of agricultural biodiversity, participation in decision-making concerning its conservation, benefit sharing and the existence of a supportive policy and seed regulatory framework.”

Historically, community seedbanks existed some 3,000-5,000 years ago. Biblical scholars studying the seven years of famine in Egypt during Joseph's time say “During the good years, the crops were excellent, and appear to have given more than double the harvest of a normal year. That would mean that even with Joseph's 20% tax, each farmer would have 160% of the grain from a normal year. If they sold all of their regular harvest, that still leaves 60% for them to do with as they please, including saving seeds for future planting in their homes and communities.”

This belies some in the scientific community who claim community seed banks first appeared towards the end of the 1980s, established with the support of international and national nongovernmental organizations.

Community Seed Banks by Ronnie Vernooy, Pitambar Shrestha and Bhuwon Sthapit say countries that pioneered various types of community seed banks include Bangladesh, Brazil, Ethiopia, India, Nepal, Nicaragua, the Philippines and Zimbabwe.

In the Global North, a particular type of community seed bank emerged known as a seed-savers network. Such networks were first established in Australia, Canada, the UK and the USA before spreading to other countries. Over time, the number and diversity of seed banks have grown. In Nepal, for example, there are now more than 100 self-described community seed banks whose functions range from pure conservation to commercial seed production. In Brazil, community seed banks operate in various regions of the country.

Empowered Community Seedbanks, Microcenters of Biodiversity

In Bolivia, of the 4,500 potato varieties grown in South America, 1000 to 3,290 varieties are found in Bolivian farmers' hands. The great diversity of potatoes has survived eight millenia because of the life and culture of the Andean farmers and communities that grow the crop.

Ximena Cadima of the PROINPA Foundation, a farmers' organization said the diversity of Bolivian potatoes was and still is being conserved in situ under traditional farming systems in specific geographic areas known as “microcenters of biodiversity.”

Much of the diversity has been collected and conservved ex situ by PROINPA, integrating it with in situ, combining the knowledge generated by farmers' experiments with traditional knowledge of farming communities, Cadima revealed.

It has resulted to:

--Community empowerment as local farming families are able to appreciate the value and uniqueness of their agricultural biodiversity

--Increased awareness as more sensitive social environments are being created that are open to conservation of agricultural biodiversity

--Strenghtening of farming systems as traditional farming systems reintroduce native potato varieties in farms where the varieties were lost

--Create new markets as new initiatives link farmers to markets

In the Wello region of Ethiopia, a farmer- run initiative Ethno Organic Seed Action (EOSA) ensures seed supply system enabling food security through reliable access to planting materials.

Regissa Feyeessa, EOSA president said “ our community-based seedbanks for sorghum constitutes the sorghum bread basket of Ethiopia. It is hard to imagine drought and famine devastated our regions but over time, we developed a comprehensive approach that empowered farmers.”

“Community seed banks have been the key part of this strategy, “ she beamed, recalling EOSA's experiences.

In EOSA's community seedbanks, farmers maintain collection of germplasm. Each family contributes a share of seed which is used to establish a 'revolving seed fund” that involves a broad set of crops and varieties. The fund consists of a seed and grain reserve that is dynamically linked to farmers' fields.

Families can borrow seeds from the fund plant it in theier fields and return mit with interest at thend of each cropping season.

This reliable point of access to diverse crops and varieties decreasesv the vulnerability of the entire communnity to genetic erosion, pests and diseases and the increasingly extreme weather patterns brought about by climate change, Feyeessa explained.

The community seedbanks provide areas for farmers' experimentation,farmer-scientist collaboration and other activities aimed at increasing productivity of farmers without compromising local crop diversity.

Traditional Practices Endure

In the Cordillera region of the Philippines, home seed and community seedbanking is as old as time immemorial. The most popular traditional way of saving seeds is the su-ulan rice storage. Almost all farming homes in the Cordillera have a su-ulan, a structure where rice harvest for food and planting is stored and prevented from rat, pest, fungus or mold infestation through smoke emanating from a hearth. This is usually located over the hearth in the kitchen . The traditional su-ulan does not only preserve, store and protect rice harvests but also corn, rootcrops, and legumes.

The su-ulan system keeps the seeds dry thereby stymying seed respiration and transpiration and prevents moisture from settling on the seeds which usually is the cause of fungal and mold infestation. Tried, tested and proven for centuries, it is the most effective traditional and effective seed conservation so far for grains, cereals, legumes and spices in this part of the country.

This and many more indigenous biodiversity approaches of local peoples deserve attention. Surpringly, community seed banks have rarely been the subject of systematic scientific enquiry. It is time they are given a second look.

Agroforestry: Balancing Biodiversity and Land Conservation and Food Production By Dr. Michael A. Bengwayan,

Agroforestry: Balancing Biodiversity and Land Conservation and Food Production
By Dr. Michael A. Bengwayan,

A Philippine environmental group Cordillera Ecological Center (CEC) walks its talk “Fight environmental decay and poverty equally with social change”.

It believes in the midst of climate upheaval, there is a need to ensure biodiversity conservation while addressing poverty effectively with radical social change paradigms because conventional methods such as those in agriculture have proven most often than not, inappropriate.

Saying many Western-introduced farming systems are taking a toll on Earth-- habitat loss, species extinction, genetic erosion, land degradation, chemical pollution and water loss,-- CEC is advocating for a return to the native.

‘Go agroforestry”, CEC says, referring to an indigenous natural knowledge, skill and practise (INKSP).

Something ASEAN agriculturists and conservationists agree with, considering the growing global concern on human, food and property losses due to worsening storms, earthquakes, wildfires, droughts, floods and volcanic eruptions, caused by climate change.

Philippines and other Asia-Pacific developing country representatives met recently are convinced there is one way to live with climate change’s impacts--focus on agroforestry, an ancient practice as a means of increasing food supply while ensuring land and biodiversity conservation.

A New Name for an Old Practice
Agroforestry is is a new name for an old practice. Historically, cultivating trees and agricultural crops in intimate combination with one another is an ancient practice that farmers have used throughout the world. It calls for the combined sustainable use of land to produce trees, food crops and livestock simultaneously with each supplementing each other in terms of fertilization, feed and forage production, crop protection.

This farming system is friendly to the land, water and other living things. The management system dates back to the time when humans transitioned from their one-dimensional hunter-gatherer subsistence and began to include agricultural practices as a means of survival.

A key component in agroforestry is in the maintenance of soil moisture, despite respites in rainfall, to provide growth of crops for human subsistence and animal forage.

Providing guidelines on the use of the discipline is the Indonesia-based World Agroforestry Centre Southeast Asia (ICRAF-SEA) and the Asian Association of Agricultural Colleges and Universities (AAACU).

ICRAF harnesses the benefits of trees for people and the environment through science, and farmers’ knowledge and practices, to ensure food security and environmental sustainability. AAACU is an organization of Asian universities offering college and graduate degrees in agroforestry.

Ranking officials met recently to assess progress of agroforestry in the region and how this environment-sustaining land use system can further be developed to promote food production.

Agroforestry and Climate Change
In Southeast Asia, ICRAF and AAACU are working to expand agroforestry strategies as means to increase resilience to climate change, natural disasters and other shocks.

They support governments, communities, NGOs and the private sector in Cambodia, Indonesia, Lao PDR, Myanmar, Philippines, Thailand and Viet Nam, and other ASEAN member states and neighbours..

Their work promotes agroforestry techniques that reduce greenhouse-gas emissions with farmers.

It includes land-use planning for low carbon dioxide emission and multiple environmental services like landscape restoration, livelihood improvement, and ecosystem services.

Agroforestry ensures that at least 50 to 60 percent of a farmland is devoted to trees preferably a mixture of fruit-bearing, non fruit-bearing and nitrogen-fixing trees. These provides for trees ready to sequester dangerous greenhouse gasses like CO2 and replenish oxygen supply and water supply thereby help in cooling the earth.

Carbon sequestration, the process by which carbon dioxide is removed from the atmosphere and held in either a solid or liquid form. Scientifically speaking agroforestry is good because it increases carbon sequestration in the soil,

Agroforestry enhances natural climatic phenomena like oxygen cycle, nitrogen cycle, and water cycle which have now become erratic due to adverse effects of climate change.

Ensuring Sustainable Food Supply
Trees are the basic component behind agroforestry and are seen as not only source of human food but also for livestock while making croplands fertilized and rich naturally as land is saved and water is conserved.

The Creator’s magic behind this is there are trees that naturally fertilize the soil with nitrogen, the most important element in food production. Called nitrogen fixing trees (eg. Calliandra calothyrsus, Ipil-ipilg or Lucaena lucaena, Flemingia macrophylla, Sesbania sesban), root nodules of these trees contain Rhizoctonia bacteria that are able to fix nitrogen from the atmosphere into available fertilizer for food crops thereby eliminating fertilizer costs by farmers.

Trees also store water during rainy season, one tree storing as much as 150 to 200 liters per year and release the water during summer to recharge brooks, rivers and springs needed for irrigating crops.

Trees keep the greenery, and the soil moisture is also maintained for food crops. For agriculture, soil moisture is the most important, next to rain, farmer care about how much soil moisture is collected during the rain.

Today, many farming systems include trees not only to sustain food crop production but also to feed their livestock. For instance, goats are raised with mulberry and Flemingia leaves, cattle and swine with Calliandra a Lucaena, rabbits wit Prosopis joliflora. Flemingia are used in alley cropping with corn, vegetables, spices as fertilizer. More than these, the trees serve as habitat for smaller wildlife, birds and insects, ensuring natural resource management.

Indigenous Agroforestry Systems
In the Philippines, the most notable indigenous agroforestry systems are the muyung or pinugo of the Ifugaos, the tayan of the Bontocs, the lakon or batangan of the Iappais or Western Bontocs and the lapats of the Tigguians and Isnegs of the Cordillera region.

These highlight cultivated trees with rice and agricultural crops in intimate combination with one another in ancient practices that farmers have used throughout the ages born out of a need to fulfill immediate basic human needs of food, medicine, fuel, fodder, shelter, protection etc.

Cordillera farmers also establish a complex and somewhat sophisticated type of “shifting cultivation” where in clearing the forest for agricultural use, they deliberately spare certain trees which by the end of the rice growing season provide partial canopy of new foliage to prevent excessive exposure of the soil to the sun. These were an indispensable farming system here and were either planted or preserved from the original forest to provide food, medicines,construction wood and cosmetics.

In Indonesia, it has been a long time traditional practice for farmers to plant an average of two dozen species of plants on plots larger than one-tenth of an hectare. For example, a farmer would coconut (Cocus nucifera) or Pawpaw (Carica papaya) with a lower layer of bananas or Citrus, a shrub layer of coffee or cacao, annuals of different stature such as maize and finally a spreading grown cover such as squash. Such an intimate mixture of various plants, each with a different structure, imitated the layered configuration of mixed tropical forests.

In Burma, it established teak tree (Tectona grandis) plantation by using a method called “Taungya” which later became the most efficient way of planting teak. The taungya system established teak forest plantations using available unemployed or landless laborers. In return for performing forestry tasks, the laborers are allowed to cultivate the land between the rows of tree seedlings to grow fruit trees, vegetables and spices as well as rootcrops.

ICRAF, AACU Targets
Today, ICRAF and AACU member countries have agreed to aggressively implement agroforestry practices after an ASEAN top agriculturists’ meeting at the University of the Philippines at Los Banos,

They agreed, among others, that their countries:
--offer and share agricultural courses, initiate research and development projects
--undertake collective research and training of extension workers and farmer leaders
--solve tree biodiversity problems in Malaysia and initiate agroforestry models for Thailand
--train agroforestry experts for Indonesia

Much still remains to be done to develop agroforestry as a model for biodiversity conservation in the face of climate change while maintaining agricultural productivity.

And considering Asia-Pacific countries’ skyrocketing population and fast-depleting natural resources, no better time than now, is agroforestry needed with urgency.

ALNUS AGROFORESTRY

Alnus Tree-Based Agroforestry Saves Land, Food, Biodiversity

By Michael A. Bengwayan

Alnus japonica or Japanese alder tree, when used as agroforest dominant tree saves soil, food crops and biodiversity.

Alnus is a non leguminous nitrogen fixing tree species. a deciduous or semi-deciduous tree with a straight trunk, up to 30 m in height and 60 cm (rarely to 2 m) in diameter; twigs ribbed,

glabrescent; bark dark grey, often with yellowish patches and slightly raised lenticels. Leaves are alternate, elliptical, ovate to oblong, yellow-brown scales; petiole strong.

It is native to northeast Asia—Taiwan, Japan, Korea, Russia, and China.

Studies suggest the stems, bark and leaves have antioxidant, hepatoprotective, cytotoxic, anticancer, antiatherosclerotic, antiviral, anti-trypanosomal, antiproliferative, pro-apoptotic properties.

Alder Gets to the Philippines

Alnus japonica was introduced in the Philippines during the Second World War particularly in Baguio City by the Japanese.

Alder is now common on higher altitude. The climatic conditions of the Cordillera favors the tree. it grows well in full light but will also tolerate shade. At lower altitudes, it occurs in moist sites, such as near rivers, but it will colonize in rocky sites exposed by landslides or land abandoned after cultivation. It occurs naturally in both pure and mixed stands and is common in streambeds, near streams, in ravines and in drier forests. It is found naturally in moist, cool,

subtropical monsoon climates with a dry season of 4-8 months; it also grows in humid, cool or subtropical mountain areas in tropical zones with high rainfall.

.

Alnus prefers moist and well-draied soils, including loam and loamy sand gravel, sand and clay. It does not require high soil fertility but prefers permeable soils. Grows well on soils with high water content but not on waterlogged soils.

Restoring Poor Lands

Alnus restores soil fertiliity through nitrogen fixation that takes place through a symbiotic relationship between Alnus with nitrogen-fixing actinomycetes of the genus Frankia and is therefore able to improve degraded lands .

Symbiotic Frankia are located in specialised structures, or nodules, along the root system of the host plants. The root nodules are analogous to those induced by Rhizobium in legumes, and they provide an environment, where Frankia can grow and prosper, while providing the host-plant with fixed nitrogen.

Unlike the Rhizobium-legume symbiosis, where most of the host plants belong to a single large family, Frankia can form root nodules in symbiosis with actinorhizal plants distributed among eight families consisting of over 200 species of angiosperms.

The value of alder tree was recognized by the tribal farmers long back and more than 80 yrs old trees can be seen in the area.

Agricultural crops, together with alder trees forms a very remunerative agro-forestry system and the ability of the tree to develop and retain soil fertility has been fully utilized by the tribal

farmers of of the Cordilleras.

Soil conservation

Soil erosion due to high rainfall and hilly topography is very high in most of the Cordillera provinces. There is great need to check the rate of soil erosion. In this regard, the deep root system of alnus gives some stability to slopes that tend to slip and erode. Its seeds have been broadcast to stabilize landslides area effectively used to reforest abandoned kaingin land areas.

Because it grows as a pioneer in degraded habitats with low fertility soils, alnus can also be planted to improve the stability of slopes liable to erosion and landslides, and for forest reclamation.

Considerable quantities of nutrients are recycled through the litter of Alnus sp. Leaf and twig litter of Alnus may produce 3-6 t/ha litter annually, containing N 3.4-3.7 gm, P 0.08-0.1 gm, K 0.6-0.7 gm and Ca 0.2 gm per 100 gm dry matter.

Intercropping

Cordi farmers can grow paddy rice in Alder based agroforestry system. The high rate of regrowth of Alder helps in supplying

good quantity of biomass for nutrient enrichment the soil. It is a good crop for intercropping. In some of horticulture crops coffee, , this is grown as shade crop. On terraced slopes, the species is commonly pollarded for poles and inter planted with crops like maize, beans, chili and pumpkin.

Other Benefits

The foliage is of low to moderate value as fodder for ruminants. It has a low calorific value of 18,230 kJ/kg. It dries easily, burns well and is an important source of firewood and charcoal. In the Philippines, kraft pulping of wood of Alnus sp gives a pulp yield of 47.6%, and bleaching improves the brightness to 76%. It is suitable for the manufacture of high-quality paper.

The Real Earth-Keepers.....

The Real Earth-Keepers.....

...By Michael A. Bengwayan....



Some ten years ago, my last child Fran taking up Biology said “I have need of skeletized leaves for my molecular biology class”, Having that in mind, I trudged to the garden and poured over the leaves carpeting the ground. carefully brushing aside the brown and yellow litter, iI saw several leaves without their tissues, their venation magically left, beautifully carved out from what used to be chlorophyll-packed and organized epidermis, lignin, mesophyll and vascular tissues.



I texted Frances back that the nature’s gifts were just there waiting. but I didn’t see her enter the garden gate that day. or the following day. it was her sister Abigail, having heard of the same need uttered, who went to choose several deveined beauties.



I had no feeling of urgency to help…it was a simple thing to do…but which gives a boundless joy of discovery. I looked at my compost pile, wondering, knowing and aware of what caused the venation. I am quite adept about it, having taught the knowledge to countless farmers many years.



The venation is caused by century bugs…to be more precise, woodlice or woodlouses. These are nature’s primary decomposers. we have three common woodlice stamping the Cordillera forests and soils in the Philippines; first we have the sowbug, by far the most common woodlouse underneath the wood. It has a smooth texture and has a wide flat oval like shape. when disturbed it tends to freeze before moving off. this sowbug is usually brown to black in colour and is spotted with yellow or white.



Then you have the second most common woodbug, the common rough woodlouse . The most obvious difference with this woodlouse is the textured surface and colouration. This species is a dark flat-gray with a bumpy, tubercle covered back. Looking a little closer you’ll notice that it has three distinct lobes at the front of the head instead of two that you’d find on the sowbug.



And most likely that you’ll discover is the common pill-bug. you can separate the pill-bug from the sowbugs and woodlice by the fact that it curls up into a perfect ball when threatened. The colouration is somewhat similar to the sowbug in that it is slate gray with some mottled yellow markings. however, when unrolled it has a smoother, rounded look to it and lacks the prominent tails that make it different from the sowbug.



I have thousands, perhaps millions of these bugs in my garden. they’re friends. our friends, farmers’ friends, life’s friends. So I patiently on Sunday scraped-off humus to show to my eight year old grandson Seth Chadlos .I wanted him to see and even understand that those crawling bugs fleeing for their lives when touched, are harmless friends.



It was a quality time spent with him.



We looked under pieces of wood and stones on the ground. We discovered all sorts of bugs and watched them scurry from the newly exposed surface for the safety and moisture of the dark underside of the wood and other debris. It was quite fascinating to watch these crowds of “bugs” hurrying for cover. a few rolled up into balls in an attempt to protect themselves. since they’re mostly detritus eaters, feeding on dead leaves and decaying material (and sometimes each other) means that they’re not really harming garden plants. they’re definitely very cool creatures.



Bugs… Chadlos was not minding them a bit, he appeared awe-struck, poking at them with a stick. grayish marvel monsters, raking up dead leaves and spitting on their meal to soften it with chemistry. little-noticed mass of grounded beauty, whether created by science or God. most likely by God to be explained by science.



Will these be obliterated too by man’s stupid notions? Most likely. I wanted to stay longer in the garden to get some answers. but squinting at the last woodlouse scurrying for dear life from Chadlos’ threatening stick, I knew our time in the garden was up. I promised myself a run. It was becoming hot, a perfect time to break a sweat.



Hoisting Chadlos with my left arm as he struggled and bawled for more time to scrutinize the bugs, I closed the garden gate. We will visit the century bugs some other day again. for me to seek my own answers.



And to let Chadlos seek his.
