RICE IS NOT AN AQUATIC PLANT. Therefore, it doesn't need to be grown in water, but it's long been grown in water to moisturize and control aerobic weeds. Using biodegradable films, grow rice outside the water while controlling weeds and moisturising.

Our Solution Seed Film Cultivation (SFC) is the direct seeding of rice in dry soil using biodegradable film (biofilm). SFC refers to a farming method in which seeds are attached to a biofilm and the film is spread on dry farmland, covered with soil thinly and grown in rainwater. When rainwater is scarce, irrigation is aided using sprinklers and/or drip irrigation. To begin with, in order to ...

Our Solution Seed Film Cultivation (SFC) is the direct seeding of rice in dry soil using biodegradable film (biofilm). SFC refers to a farming method in which seeds are attached to a biofilm and the film is spread on dry farmland, covered with soil thinly and grown in rainwater. When rainwater is scarce, irrigation is aided using sprinklers and/or drip irrigation. To begin with, in order to back up our argument, would like to share the farming records with SFC. In 2017, the first year of China, about 7 tons/ha of paddy rice were harvested in cornfields. http://seedfilm.co.kr/en/case/2017-china/ In 2018, the second year, an average of 8 tons of paddy rice was harvested in a 6.7 ha (100 mu) wheat field/cornfield. http://seedfilm.co.kr/en/case/2018-china/ In conclusion, through the 3 years of rice farming with SFC in Chinese wheat/corn fields, it was proved that high-yield rice cultivation is possible in rainfed uplands, where irrigated rice farming was not possible. 4_ Technical composition of SFC Seed-attacher attaches rice seeds to the biofilm. And farmers spread the seed-attached biofilm on dry field, cover the film with soil thinly, and grow rice with rainwater, sprinklers, pivot irrigation, or drip irrigation. The biofilms decompose into 100% water and carbon dioxide (CO2). The raw materials consist of PLA (Polylactic acid), and PBAT (Polybutylene adipate terephthalate), both of which are pure biodegradable. As of 2020, the price of biofilm is US$600 per hectare.

Stage 4: Transition to Scale

Rice cultivation has been successful for three years in former corn/wheat fields where rice cultivation was impossible. http://seedfilm.co.kr/en/case/2018-china/ http://seedfilm.co.kr/en/case/2018-korea/ http://seedfilm.co.kr/en/case/2017-china/

Problem

Rice, a staple food for more than half of the world's population, is mostly grown in waterlogged paddy worldwide. However, in order to keep the rice paddy filled with water, a total of about 100 cm of water is added during the growing season in general, which means 10,000 tons of water per hectare. Currently, humans use at least 2 tons of water to produce 1 kg of rice. To make matters worse, when rice is grown in water, the anaerobic decomposition of organic matter produces methane (CH4) with a global warming potential of 28-36 based on the US Environmental Protection Agency. About 10 tons of CO2eq are emitted per hectare due to methane in irrigated rice fields.

Solution

West Africa's annual rice imports were 1.7 million tons in the early 1990s, but now it has grown up to 10 Mt, half of its consumption, $4.5 billion. Now, about 9 Mha of farmland produce 18 Mt of paddy rice with a yield of only 2 t/ha. If the yield could be raised from 2 to 4 t, West Africa could be self-sufficient in rice. We propose an innovative way that increases the yield up to 6 t/ha of paddy rice using biodegradable film that will be provided free of charge by Clean Development Mechanism.

Target Beneficiaries

Africa imports rice despite having 600 million hectares of uncultivated arable land mostly belonging to rainfed upland. Governments encourage in vain to grow rice here, but farmers reluctant because they suffer losses. According to Rice Almanac(2013), yield in irrigated rice paddy exceeds 5.5 tons/ha, while rainfed upland yields only 1 ton. SFC benefits farmers in rainfed upland by high yields and low labor, allowing them to be willing to expand rice areas, enabling rice self-sufficiency.

Mission and Vision

Rice resorting to continuous flood irrigation is unsustainable due to huge water use and GHG emissions. Rice must be grown outside the water. Fortunately, in Africa alone, the 600 million hectares of uncultivated rainfed upland will give us an alternative. • Mission Supporting African countries to become self-sufficient in rice using SFC with rainwater irrigation in the rainfed upland • Vision Disseminating SFC around the world to grow rice outside of water to adapt to climate change

Competitive Advantage

SFC reduces GHG emissions by about 9t CO2eq per hectare and saves water more than 50%. A) Water saving According to the recent study (bhone Nay-Htoon, 2016), on the premise that crop growing season of 120 days, the amount of water for irrigated rice farming consumed is about 10cm. This means that in the study, about 90% of the irrigation water was wasted by evaporation, underground percolation, etc. However, waste of water to some extent is inevitable. SFC can saves more than 50% water compared to irrigated rice farming. B) GHG reduction (1) Methane emitted in rice fields: 348-413 kg/ha (peischl et. al, 2012) (2) GWP of methane: 28-36 Based on 1) and 2), GHG due to methane in rice fields is 9.7-14.9 t CO2eq/ha. it is indicated as 10 tons CO2eq. (3) According to a recent study (b choi et.al, 2018), our biofilms using PLA/PBAT release about 1 tCO2eq per hectare. (4) In conclusion, SFC mitigates GHG emissions by about 9 tons CO2eq per hectare compared to irrigated rice farming.

Planned Goals and Milestones

Desertification is underway worldwide due to climate change. Coping with the challenge, The Great Green Wall Initiative is planting trees in the Sahel region. But, tree transplantation may not be able to keep up with the pace of desertification in progress. SFC can be applied to desert greening. Biodegradable film for rice farming should be decomposed within 6 months, but for desert greening, it should not decompose for more than 5 years. Acacia seeds with PLA film can make the desert forest.
