Asia is Earth's largest and most populous continent. It hosts many densely populated and large cities as well as enormous barely populated regions, which all together host over half of the human population. Agriculture as a source of income is of major importance in the region. In most Asian countries, agriculture is the biggest user of water and in some regions can be responsible for to 90% of total water consumption through irrigation.
The impacts of palm oil plantations on human wellbeing depend on context and are neither uniformly negative nor positive, finds this study of villages in Indonesia. Oil palm plantations are more likely to lead to improved basic, physical and financial well-being in villages with relatively low existing forest cover and where most people make a living by producing goods for market, compared to villages with higher forest cover and where most people have subsistence-based livelihoods.
This feature in the UK’s Guardian newspaper examines the environmental implications of China’s promotion of milk consumption. Dairy consumption in China has grown from very little to around 30 kg per year within the last few decades, and government guidelines recommend that people triple their current dairy consumption.
This open access book by Prabhu Pingali, Anaka Aiyar, Mathew Abraham and Andaleeb Rahman uses a food systems lens to explore issues of food security in India and to set policy goals for 2030 and 2050.
This paper uses long-term studies from Europe and China to examine the effects on soil quality of organic matter addition, no-till practices, crop rotation and organic farming. It finds that yields are lower under no-till and organic practices, but that these practices are associated with higher soil organic matter.
According to this paper, 23% of deforestation in Indonesia between 2001 and 2016 was caused by palm oil plantations, 20% by conversion of forests to grasslands or shrublands (including conversion caused by fire), 15% by small-scale agriculture, 14% by timber plantations, and the remainder due to other causes including logging roads, mining and fish ponds.
This paper explores the influence that the Coca-Cola Company has had on obesity science and policy in China, in part through Coca-Cola’s influence on the International Life Sciences Institute (ILSI). The author notes that China’s health recommendations usually focus on physical activity instead of the dietary policies recommended by the World Health Organisation - in line with Coca-Cola’s message that all food and drinks can be part of a healthy diet, as long as there is enough exercise.
This paper performs a cost-benefit analysis for various climate-smart agriculture practices on farms in Vietnam, Nicaragua and Uganda, including switching annual to perennial crops (e.g. coconut), crop rotations, using organic fertiliser and intercropping maize and beans.
Facial recognition could be used on pig farms in China to provide individualised feeding plans. The artificial intelligence system, created by a subsidiary of Chinese e-commerce company JD, can also track a pig’s growth, physical condition and vaccinations over its lifespan.
The book “Organic Food and Farming in China: Top-down and Bottom-up Ecological Initiatives”, by Steffanie Scott, Zhenzhong Si, Theresa Schumilas and Aijuan Chen, examines the development of the organic food sector in China and its influences from both the state and grassroots actors.
The book “Farm to Fingers: The culture and politics of food in contemporary India”, edited by Kiranmayi Bhushi, explores diverse viewpoints on current food issues in India, including food security, global policies, and the impact of food bloggers.
Rice cultivation emits methane and nitrous oxide, which are both more potent greenhouse gases than carbon dioxide. Policies to reduce methane emissions from rice farming generally recommend using intermittent (as opposed to continuous) flooding. However, intermittent flooding could produce much higher nitrous oxide emissions than continuous flooding, according to a recent paper.
A recent paper assesses the carbon implications of converting Indonesian rainforests to oil palm monocultures, rubber monocultures or rubber agroforestry systems (known as “jungle rubber”). It finds that carbon losses are greatest from oil palm plantations and lowest from jungle rubber systems, in all cases being mainly from loss of aboveground carbon stocks. The paper points out that, “Thorough assessments of land-use impacts on resources such as biodiversity, nutrients, and water must complement this synthesis on C but are still not available.”
FCRN member Dr Rosemary Green of the London School of Hygiene & Tropical Medicine has published a paper that calculates the greenhouse gas (GHG) emissions and water use associated with five dietary patterns in India. As shown below, GHG emissions per capita are highest for the “rice and meat” dietary pattern (at 1.2 tonnes CO2 eq. per year) and lowest for the “wheat, rice and oils” pattern (at 0.8 tonnes CO2 eq. per year). For comparison, per capita dietary GHG emissions in the UK have been estimated at 2.6 tonnes CO2 eq. per year for high meat eaters and 1.1 tonnes CO2 eq. per year for vegans (Scarborough et al., 2014). Water use is highest for the “wheat, rice and oils” pattern and lowest for the “rice and low diversity” pattern.
A project in Ladakh, India, creates “ice stupas”, a form of artificial glacier, to complement intermittent water flow from retreating natural glaciers. Water from streams is sprayed from vertical pipes during the winter, freezing into pointed mounds, which melt slowly throughout the year, irrigating crops in the summer.
