In the last two centuries, our haste towards development and progress have resulted in widespread degradation of the earth’s ecosystem. Improper disposal of industrial and domestic wastes have polluted the soil, water, and air. In certain parts our atmosphere is partly blanketed with greenhouse gases which trap the deflected sun rays and prevent them to escape. Land denudation, deforestration, diminishing biodiversity, burgeoning population, and not to mention wars further add to the earth’s crisis. Global climate change is a clear example of the sum effect of man’s negative follies on the ecosystem. Equitable climate means survival for all living things and preservation of the non-living.
To face the environmental challenges on the ecosystem, organisations at various levels - internationally, nationally, communally, and individually are taking remedial measures sustainable ecosystems. Malaysia is promoting going green (biodiesel, biodiversity conservation, sustainable agriculture), renewable energy use (solar and hydro power), cutting down plastic use, and waste recycling.
Agriculture is the mainstay of this country. The practice of sustainable agriculture is viewed to be of utmost importance for economic production for the long term. It hinges on optimising the use of resources of the ecosystem - water, topography, fertility, weather, pest and diseases to match with arability of the crop(s) to be grown. The use of modern and appropriate technologies must go in tandem in all aspects of production, processing, and marketing. Agricultural pollution could be minimised by judicial use of fertiliser and pesticides for example.
In organic farming (OM) system, pesticides and chemical fertilizers are not applied in the growing of crops. If used at all it will be minimal and under unavoidable situations. This environmental friendly approach is one of the ways towards sustainable agriculture. However, it is intensive in terms of labour especially may not be suitable for large scale agriculture.
Nature farming (NF) is another approach towards sustainable agriculture. It is less intensive. The concept is to adapt crop and/or animal husbandry to the inherent characteristics of the land. It is to harness and merge the latent energies of the diverse elements in the system to productive use. Biotic factors such as root competition, plant growth habit, storied and shade effects, animals, and abiotic such as weather, soil condition, rocks that persist in sub-ecosystem are taken advantage in the interplay and relationships they may have - neutral, synergistic, symbiotic, antagonistic. The use of diverse plant species from ground cover to tall trees to beneficial use means that it is a sort of disorganised mixed farming of the wild. However, there is order in the disorder. Also, NF is perhaps an advanced form of traditional agriculture with basic scientific concepts applied.
The oil palm, the most efficient converter of the sun’s energy to edible oil is a good candidate for nature farming that shows intricacies of man-animal-plant-environment relationships and energy flow. From the start, if the area is bushy with small trees, just clear (with bulldozer) the planting row and plant the oil palm seedlings. The lining may not be accurate to our liking but good enough. Within a couple of years the young palms will overshoot the tops of the bushes. The vigorous fibrous root system can cover a wide area and would soon overwhelm the root systems of lalang and grasses around it. Within three years the lalang and other undergrowths will be overshaded by the palm fronds and die off. The small trees can be gradually cut down or pollarded. If there are buffaloes grazing in the area they will help to clear the wild grasses and vines and make walking paths. They will however munch the shoot and leaves of young palms. Being fast growers, the palms will recover with new cycle of leaves and stunting is minimal. Buffaloes will scare away snakes in the area and make it safe to work. If there are muddy pools the buffaloes would wallow in them to cool off. Their droppings add fertility to the soil that benefit the earthworms and plants. They attract leeches that suck human blood to give the ‘bekam’ effect if one gets bitten. It is a pleasant sight to see egrets land on the backs of buffaloes doing a favour looking for ticks. Monkeys and wild pigs deprived of their original habitats would pick fruits from the low bunches. Their tracks result in the area around the base of palm clear allowing easy access for harvesting. Those animals deserve a share of the harvest. Cabbage from unwanted non-bearing palms can be harvested and cooked. Fresh leaves and pellets made from the fronds provide feed to goats, sheep, and cattle.
As a plantation crop, the oil palm has been much criticised for environmental destruction by the west. They may have a point. It is the planters to be blamed. At any scale of operations, riparian reserve should be left undisturbed to allow water catchment and wild animals to live. The mega FELDA Lahad Datu oil palm scheme left nothing for orang utan haven. It has caused irreversible damage to the riverine system, biodiversity, environment, and people inhabitants of the jungle.
