Increasing Food Agriculture Productivity: Biochar Application or Forest Clearing for Food Estate?

Indonesia currently ranks 69th out of 113 countries in 2022 in food security and this is lower than Malaysia and Vietnam with indicator points below the global average. This condition is concerning considering that Indonesia was once self-sufficient in food before and even the price of rice in Indonesia is the most expensive in ASEAN. Efforts to maintain food productivity are indeed a challenge, let alone increasing it. Along with increasing population growth, the need for food automatically increases. The condition of declining food production and productivity is related to a number of factors including land conversion to non-agricultural land, and soil / land damage. A number of regulations have been made to stem the rate of decline in food productivity due to these two things.

Regarding land damage, repair efforts need to be made so that agricultural productivity increases. It is estimated that the area of ​​land damage that occurs is very large with a high level of severity. This requires gradual and sustainable repair efforts with various strategies including improving farming patterns and even a number of incentives. Only with these efforts can the agricultural sector as a source of food be repaired or if not, the damage to agricultural land will get worse so that repair efforts will be more difficult.

Biochar application or forest clearing for food estate ?
Biochar application will be able to repair damaged lands. In addition to being a slow-release fertilizer agent so that fertilizer use becomes efficient and does not pollute the environment, increasing soil pH, increasing soil organic carbon and increasing agricultural productivity, biochar will also help overcome the management of agricultural waste that has so far polluted the environment. The increase in agricultural productivity from the use of biochar is on average around 20%. If Indonesia's current rice production is around 31 million tons per year, then the application of biochar will increase total rice production to 37.2 million tons (an increase of 6.2 million tons). With an average rice production per hectare of 6 tons, the increase of 6.2 million tons is equivalent to increasing the area of ​​agricultural land by 1.03 million hectares. Even damaged land from post-mining can be reclaimed and rehabilitated with the application of biochar, with the land area also reaching millions of hectares. This is certainly better than clearing new forest land for food estates because of its environmental impact. 

As the human population grows, the need for food and energy will continue to increase. Indonesia's population in 2045 is estimated to reach 319 million people and the world's population in 2050 is approaching 10 billion people. The need and urgency of biochar to improve soil quality is increasing. Tens of millions of hectares of all Indonesian acidic soils, which are classified as dry land acidic soils, need to be improved with biochar. This means that the business potential reaches billions of dollars or trillions of rupiah. Meanwhile, rice imports in 2024 are targeted to reach 3.6 million tons (as a buffer), a large amount. With an annual rice requirement of around 31 million tons, the contribution of imported rice reaches more than 10%.

Biochar in addition to repairing soil damage so that it increases its fertility which ultimately increases agricultural productivity is also part of the climate solution, namely by means of carbon sequestration. Biochar applied to the soil will last hundreds or even thousands years, and does not decompose. This is another advantageous factor for biochar producers, namely getting carbon credits. The quality of biochar will determine the acquisition or price of the carbon credit, so that the raw materials of biochar and its production process are affected. The price of carbon credits is increasing so that it is increasingly attractive and also the carbon credit market continues to grow.

Damage to land or agricultural land that occurs is mostly caused by excessive use of chemical fertilizers. If the use of chemical fertilizers can be reduced in dosage or with sufficient use, there will be improvements in land quality. Even if chemical fertilizers are gradually reduced in dosage and organic fertilizers / compost are increasingly added so that in the end chemical fertilizers are not used at all, soil fertility will be optimal as well as agricultural productivity.

Of course, this requires time and continuous effort. Livestock must also be encouraged so that compost / organic fertilizer can also be produced sufficiently from the processing of livestock manure. Integrated farming with livestock is the best solution for improving agricultural land with biochar, especially increasing the efficiency of fertilization. If the above can be implemented properly, then forest clearing for food estate land can also be slowed down / held back by considering all aspects comprehensively so that it is not a short-term solution that tends to be forced, and rushed because of the regime's image efforts even at a cost of hundreds of trillions.
