That Muslims should organize in the management of land - grasslands or sources of food, water, fire or energy it is clear there in the direction of the Prophet Muhammad: "The Muslims were syirkah (cooperation) in three ways pasture, water and fire" (HR . Sunan Abu Daud).
What are the consequences when we ignore these instructions - that is when we do not bersyirkah among us? Sources of livelihood are our primary form of food, water and energy managed by others and people become not self-sufficient in meeting the main of needs. When we are not self-sufficient in terms of basic needs, we are easily misled in a variety of other matters. Then the great work for people with learning syirkah in three main points as much as possible should be initiated.
In matters of energy the Muslims must start His guidance, what are the Qur'an speaks regarding the fire or energy? Qur'an talk about the source of fire from green trees (Surah 36: 80 and Surah 56: 71-72). In a matter of human beings could be the most efficient source of energy that nuclear power, which is the most clean hydro power, which is the most abundant solar energy. But when Allah SWT hinted fire from green trees, certainly a source of energy that this one has its own advantages. For example when we have firewood or wood pellets (the cutting edge the fuel) from the woody biomass then can we save, we can use at any given time, relatively unaffected by weather conditions. Unlike hydro (water) and solar energy availability and use is affected by weather conditions. Plants or green trees also absorb CO2 and release O2 for us to breathe. In addition the plant is also able to fertilize the soil, resisting erosion and of course there are many more details. Furthermore, the text below will describe a small part of the energy advantages of green trees and environmental benefits.
According to the FAO estimated one third of the world soil layer has been damaged or degraded. Though the land is an important part in supporting life on earth. We know the food chain from plants. The life human and animal from plants. Most of our food comes from the ground, although there is plants and animals that live in the sea. Especially in agriculture, the land becomes the most important factor that determines the land is an important part in supporting life on earth. Land degradation occurs due to erosion, compaction, ground cover, the use of agricultural chemicals and soil nutrient depletion, acidification, pollution and other processes caused by land management practices that are not sustainable.
FAO Director General Jose Graziano da Silva estimates that by 2050 the fertile soil in the world lived a quarter of the benchmark in 1960. As the growth of world population continues to increase with the forecast to 10 billion in 2050 and is now almost 2 billion only experiencing food shortage, of course decreasing the amount of fertile land further aggravate the condition. Instructions from the Qur’an above which the plant types Leguminoceae then attempt to restore the soil fertility is feasible. Leguminoceae plant will capture nitrogen from the air is then stored in the root nodules and into soil fertilizer. Additionally leaves are also rich in nitrogen, when falling to the soil also will become fertilizer that fertilizes the land. When the soil has been broken so need to be restored then the legumes plants is the most suitable in these conditions. This is because such plants legumes have these characteristics: cool / moisten the soil surface, root nodules for being able to fix nitrogen from the atmosphere means that is able to fertilize the soil is damaged / barren, and able to prevent erosion. Rhizobium is a type of bacteria that grow in the roots of leguminoceae plants and act bind nitrogen in nodules. According to FAO, small organisms such as bacteria and fungi in underground acts as a primary agent driving the cycle of nutrients and helps plants through improved nutrient intake, which in turn support the biodiversity on the ground as well.
Among the more than 19,000 kinds of Leguminoceae, Calliandra is one of them and has been developed in Indonesia. Planting Calliandra has two major benefits that restore soil fertility and production of wood for fuel, especially wood pellets. More about the pattern of utilization can be read at the link 5F Project ForThe World!. While in Indonesia alone there are hundreds of millions of hectares have not been utilized well, including many have become degraded land. One grateful for the favors of Allah SWT is with the prosperity of the earth.
Planting trees will clean the air by absorbing CO2 and produce O2. Imagine this in an era with a location not far from here, to breathe clean air people have to buy the air in the packaging - as we buy bottled water in a plastic bottle. It's very sad. In the area of Xinjiang, the region is already very bad air pollution in China, tens of millions of air in cans has been sold since last few years. And unfortunately only the rich people who can afford to buy the canned air. Islam teaches that the air and water are free goods that can be enjoyed by anyone. Important effort that can be done to make that free is still free, is to plant trees, so that it can improve the soil fertility by planting Leguminoceae plant group, clean the air, a source of energy and also absorb water.
