Marga Green Culture

Marga Green Culture is a pioneering initiative located on a sprawling 500-hectare land in Lombok, Indonesia. This project is dedicated to growing healthy organic food without the use of any chemicals. It emphasizes sustainable and natural farming practices, ensuring that both plants and farm animals are raised in an open, free environment. By avoiding chemical fertilizers and pesticides, Marga Green Culture promotes the cultivation of pure, nutritious produce, contributing to the health and well-being of consumers and the environment alike.

Pollution from agriculture negatively affects the natural environment, with iconic problems such as algal blooms and massive fish kills. On the other hand, the rising human population has a great demand for food. This tension between sufficient food production and environmental pressure from agricultural actives asks for a different way of thinking: that of sustainable green agriculture to reach blue water in our lakes, rivers and oceans. Recent research indicates five ways that help to achieve this goal. Scientists of Wageningen University & Research and Chinese colleagues from China Agricultural University, Chinese Academy of Sciences, Southwest University and Tsinghua University published a perspective article on five ways to reach green agriculture and blue water. The focus of the perspectives is on China, where the government has a strong wish to go from non-sustainable to sustainable “green” practices where enough food is produced and waters are “blue” without pollution. The authors argue a key step in achieving green agriculture and blue water in China is to re-integrate food and animal production as was in the past within China. Five ways can simultaneously help to reach this goal.

1. Implement technologies

The first way deals with actions to implement technologies. The use of already available advanced technologies is important to close the distance between crop and livestock locations. Maryna Strokal, one of the authors, states: “Closing the physical distance between large-scale livestock farms and crop production may, however, be impractical in many Chinese regions for geographical reasons, the high cost of transport, and the social desire to locate livestock farms in the vicinity of high food demanding cities. Advanced technologies, such as manure composting, can help to bring crop and livestock production closer together without reducing their physical distance.” Technologies such as manure composting with bioreactors make manure suitable for transportation over longer distances, for example by removing odors and bacteria.

2. Social interventions

Scientific knowledge is important to combine with practical knowledge. This could be done via education. An already existing example where scientific knowledge has been successfully put into practices with farmers is through the Science and Technology Backyard concept in China. This concept implies that scientists live and work with farmers to grow crops. Farmers appreciate this and receive scientific advice on the right amounts of fertilizers and timing to apply to crops and vegetables to avoid losses of nutrients to the environment. The benefits are less environmental pollution and higher crop yields. Strokal suggests that upscaling such an example to a national level will contribute to sustainable agriculture.

3. Economic interventions

Economic incentives are needed to help farmers to apply manure on land instead of applying synthetic fertilizers. Therefore, we need to search for cost-effective solutions and reduce inequities in the market environment through regulation, taxation and subsidies. Strokal: “Recycling of manure back on land could be a promising, cost-effective strategy and an alternative of dumping into waters. This supports the wish of the national government to facilitate manure recycling.” The Chinese government puts a lot of efforts to facilitate the recycling of manure on the land.

4. Policy interventions

Policies can facilitate sustainable spatial planning by considering synergies and trade-offs between agricultural policies and environmental actions. Strokal et al state: “Such policies could facilitate the implementation of innovative technologies taking into account the social and economic interventions.” It is important to integrate the five ways in policies oriented towards green (sustainable) agriculture and clean water for our future generations. Strokal et al argue that “Scientists and stakeholders can collaborate in the reintegration process through co-operative creation of new ideas, designs or values by integrating their expertise and tools. This will help in the co-development of actionable solutions with the involvement of stakeholders (e.g., local farmers).”

5. Environmental interventions

The authors see an opportunity to combine the four ways above with ecological resilience. Strokal states: “By restoring natural environments such as lakes and rivers and by constructing new wetlands, nature can support our sustainable future.”

In the wake of World War II, the nature of agriculture both intensified, with more product harvested per unit area, and extensified, with farms taking up a larger area. Subsequently, fewer and larger farms were able to meet the food needs of an increasing human population, constituting a dramatic shift from the numerous smaller farms of the past. Despite its efficiency, modern industrial agriculture has a number of drawbacks, including the degradation of ecosystems and the related biodiversity loss, a loss of crop diversity, numerous animal welfare concerns, and human health risks. Sustainable agriculture seeks to address these issues and prioritizes “planetary health,” the idea that the stability of the planet determines human well-being. Its basic tenets include promoting socioeconomic equity, earning profit, and maintaining ecosystem health. Because modern agriculture has played a substantial role in precipitating a mass extinction of plant and animal species on Earth, sustainable agriculture actively endeavours to protect and support biodiversity.

Crop production

Sustainable agriculture emphasizes planting diverse crops, including heirloom plants, which are often suited to a region’s particular climate. Rather than relying on a single crop in industrial monoculture, sustainable agriculture advocates the use of polyculture, in which multiple crops are grown together. Although polyculture is frequently more labour-intensive than industrial monoculture, polyculture can reduce the need for chemical pesticides and fertilizers and generally improves soil quality. Similarly, crop rotation can help preserve soil productivity and lessen the need for agricultural chemicals for fertilization and pest control. The use of nitrogen-fixing cover crops, smother crops, and green manures can help restore soils and reduce erosion. Composting crop residues and other agricultural wastes helps recycle nutrients back to the farmland.

Animal agriculture

Animal agriculture is a key area that sustainable agriculture seeks to reform. Livestock production is responsible for a large proportion of the greenhouse gases driving anthropogenic global warming. Sustainably managing manure and implementing animal feed additives can reduce the emissions of methane, a potent greenhouse gas.

Other methods of improving animal agriculture’s sustainability focus on maintaining livestock health. Intensive animal agriculture can spur health crises. For example, diseases including Nipah virus and swine flu have emerged from crowded factory farms. Avian influenza can be transmitted from wild birds to poultry farms and vice versa, and the disease has been responsible for the culling of millions of chickens and other poultry worldwide. Reducing animal crowding and increasing farm hygiene standards are sustainable agriculture measures that reduce the planetary health risks of cultivating livestock. On smaller-scale farms, animal and crop production are often combined to form interconnected systems that reduce waste.

Water pollution and conservation

Water conservation is a major facet of sustainable agriculture. Globally, about 70 percent of all available freshwater resources are used for agriculture. Methods of reducing water waste can involve improving water storage practices to prevent evaporation losses and seepage and planting drought-resistant crops or crops that are appropriate for the climate. Many agricultural areas rely on simple flooding, or surface irrigation, as the principle means of irrigation. However, flooding often inundates fields with more water than crops require, and significant amounts of water are lost to evaporation or during transportation from the water source. Some sustainable farmers seek to implement reduced-volume irrigation, which provides slow streams of water to meet the water needs of specific crops while lessening water waste. Sustainable agriculture also seeks to address the contamination of surface water and groundwater. Large-scale agriculture often produces pollutants, such as agrochemical runoff and pathogen-laden animal waste, that seep into bodies of water and damage the surrounding environment, affecting both wildlife and humans. Soil erosion also degrades water quality, and the loss of productive topsoil reduces crop yields and the total land available for agriculture. To reduce these impacts, farmers can reduce the frequency and intensity of tillage or practice no-till methods. Organic or synthetic fertilizers and pesticides should be applied only sparingly and during dry conditions to minimize runoff; the judicious use of agricultural chemicals can minimize air pollution caused by airborne drift. Some farmers use buffer plants near waterways to absorb polluting nutrients before they can leach into bodies of water.

Energy

Finally, sustainable agriculture calls for a shift from nonrenewable fossil fuels to clean and renewable modes of energy, which include solar, wind, nuclear, and hydroelectric power. Many sustainable farms rely on on-site wind turbines or solar panels to meet their electricity needs and may utilize electric vehicles for farm work. Innovations such as energy-efficient farm equipment and improved insulation of farm buildings can help reduce agricultural energy use. Fossil fuel consumption is associated with air pollution and acid rain and also releases carbon dioxide, one of the major drivers of global warming.
