How Neem Can Reduce the Use of Chemical Pesticides

Use of Chemical Pesticides
Despite their effectiveness in killing specific pests, historic incidents and unknowns related to chemical pesticides have led to public health concerns. Fears that people could be at risk if they consume food treated with chemical pesticides do have a foundation. Pesticides have been found to partially cause neurodegenerative disorders like Parkinson’s Disease, among other maladies. Chemical pesticides cannot choose which organisms they kill, which can lead to raised ecosystem contamination and toxicity. Not all chemical pesticides directly harm humans. However, evidence of those that do, along with evidence for unintended ecological damage, led to efforts to reduce the use of chemical pesticides.

Neem as an Alternative

One of the most concerning side-effects of the use of chemical pesticides is their effect on bee populations. Bees are vital to crop pollination and indirectly help create much of the food that humans eat. Pesticide use is a primary cause of the current decline in beehive populations. American and European beekeepers report this is at around 30% per year.  Bee population decline contributes to food scarcity and poverty. When food becomes more scarce, prices rise and more people go hungry. Current conditions necessitate implementing an alternative to chemical pesticides that is safe for humans, certain insects and plants.

New research points to naturally derived pesticides as possibly safer and less damaging to the environment. Currently, the most promising natural solution is neem oil. Neem oil is an organic, naturally-derived substance from the Neem tree. The tree grows primarily in tropical regions. These areas tend to be most affected by insect infestations and represent some of the poorest areas in the world.

Neem oil use is not a new phenomenon. Traditional Indian farming methods practiced for thousands of years, and even folk medicines incorporate neem usage. It is effective at reducing specific insect populations while having minimal noted negative effects on beneficial insects like bees and worms. A number of agricultural companies have begun using neem in their products, and its use is only expected to grow as its efficacy is increasingly verified.

Outbreak and Application in Africa

In early 2020, East Africa faced its worst locust outbreak in decades. Swarms devoured hundreds of thousands of acres, fostering hunger and fear in local communities. Millions of people became more food insecure and the use of chemical pesticides became less viable. The COVID-19 pandemic upset the global chemical supply chain, which seems to have inhibited governments from receiving the large quantities of pesticides needed to make an impact against the locust invasion.

In response, some farmers in Kenya began making their own neem oil to push back against locust invasions. Neem oil can weaken locusts’ reproductive ability and potentially kill them, which reduces the current and future populations. While it was too late to make a big impact against the swarms, individual farmers protected their crops. If enough farmers learn to make their own oil in the future, or if it is produced cheaply on a large scale, Kenya could have an effective, safe defense against locust invasions. Other countries in the region also afflicted by locust swarms stand to benefit from looking to Kenya as an example.

Potential for Future Practices

Chemical pesticide use is harmful to the environment and can create bad health outcomes for some people. Industrial use of neem oil instead of chemical pesticides could improve health conditions worldwide and protect ecosystems. On a smaller scale, it could protect the economic interests of poor farmers and people at risk of starvation. People may also be more accepting of the use of growable, natural pesticides over the use of chemical ones. Locally-made neem oil also mitigates environmental pollution. This puts more power into the hands of individual farmers. Though natural pesticide solutions require more research, they represent critical development in the future of agricultural pesticides.

India’s Ban on Dangerous Pesticides

India’s ban on dangerous pesticidesThe Indian Ministry of Agriculture has banned 27 pesticides that are known to be dangerous. A number of studies found that those who work closely with pesticides (such as farmers, pesticide applicators and crop-duster pilots) suffer an increased risk of a variety of diseases/illnesses relating to the neurological, behavioral, reproductive and developmental systems. These illnesses include leukemia, lung cancer and non-Hodgkin’s Lymphoma. As a direct result, 20,000 people die of pesticide poisoning annually in India. However, that does not account for the diseases that pesticide poisoning can lead to. Even those who are not directly related to the agricultural industry are exposed to dangerous pesticides through run-off that contaminates water sources, including drinking water. India’s ban on dangerous pesticides will lead to a major decrease in unnecessary health problems. Many farmers have admitted that they don’t have a proper understanding of how pesticides work or how to even use them correctly. As one farmer, Balbir Singh reported, “Some people use pesticides without understanding why hoping that their crops won’t die…We know we are killing our land and our people.” India’s ban on dangerous pesticides will eliminate this problem and ensure the safety of agricultural workers, as well as the general public.

Pros and Cons of Pesticides

India’s ban on dangerous pesticides is also expected to benefit the economy. The 27 banned pesticides have been outlawed in Europe and the U.S. That makes it more difficult for these countries to import crops from India in the past. However, now India is following the European Union’s guidelines for exporting crops. Individual farmers will be able to export more crops, promising an economic benefit to India’s ban on dangerous pesticides.

Many are worried about the possible negative effects of India’s ban on dangerous pesticides. Pesticides ensure crops will not be destroyed by insects, therefore allowing a maximum number of crops to be harvested and sold. Three-quarters of the Indian population work in agriculture, so a decrease in crop production would devastate the country.

A Positive Shift

However, in 2003, the small Indian state of Sikkim eliminated the use of all pesticides. The state became healthier overall and introduced price caps on produce to keep prices affordable for consumers. Wildlife flourished and in turn led to better farming land, promising higher crop levels. Compared to the rest of India, farmers using pesticides have destroyed farmland by depleting the soil’s nutrients. Sikkim serves as a model to the rest of India, proving that farmers do not need to worry about the ban of pesticides having a negative impact.

India’s ban on dangerous pesticides promises an improvement of the health, environment and economy of the country. With the organic food market growing by 25% per year, India’s steps towards agricultural improvements bring hope that more countries will be inspired by these positive changes.

Locusts Threatening Food Security in East Africa

Food Security in East AfricaAn apocalyptic scene—swarming locusts blanketing the sky. This is an image the world is mostly unfamiliar with. In fact, locusts are the oldest migratory pest in the world and are often associated with destruction.

A Snapshot of the Problem

There can be as many as 80 million locusts compacted into just a half square mile, and they bring with them devastating effects. In only one day, one square kilometer of these pests can destroy the agricultural produce that could sustain 35,000 people. The FAO states that during plagues, like the ones that occurred in East Africa during 2020, locusts can damage the livelihood of a staggering 1/10 of the world’s population.

Locust migration occurs in a cycle of boom and bust. This biological uncertainty makes it hard for countries to garner the funding, political will, knowledge and capacity to proactively address the threat through long-term infrastructure. However, failure to detect and control locusts proactively can result in devastating plagues. These can require millions of dollars to address and have catastrophic effects on food security, particularly in East Africa. The experience of one Somalian farmer portrays the catastrophic impact these pests have. Abdirahman Hussein Mohamoud relies on his farm to support his family. In May, he lost his entire $5,000 investment in crops to locusts. In his own words, his hard work “has all come to nothing.”

Possible Solutions

The FAO tries to combat the threat of locusts through early detection and warning with its Desert Locusts Information Service. USAID works towards strengthening the government’s capacity to address the threat of locus proactively in addition to the $19 million of US humanitarian response to reduce the size and impact of swarms. However, there is still an overwhelming lack of policies addressing locusts in East African countries. For this reason, there is a heavy reliance on pesticides for rapid response.

The use of pesticides, while incredibly effective for killing locusts, can negatively impact the health of humans and the environment. In Uganda, desert locusts are a common food source and the people often consume them immediately after the use of harsh pesticides. A number of community health advocates are raising concerns with the lack of adequate training and information on the potential impact these pesticides can have on human health. Executive Director of the Mpala Research Centre in northern Kenya, Dino Martins, warns that mass spraying can harm biodiversity as well. Martins points to the need to create more sustainable alternatives to controlling locusts such as biopesticides of pheromones.

Impact of COVID-19

While locusts pose a major threat to food security in East Africa, COVID-19 has made poor communities even more vulnerable. Resources for aid are stretched thin with a high priority on coronavirus relief. Despite this, countries in East Africa have maintained the control and monitoring of desert locusts as a national priority.

However, the slowdown in the global supply chain and cross-border mobility is raising concerns about the difficulty of acquiring pesticides for controlling locusts and protecting food security in East Africa. In March, an order of pesticides from Somalia to Ethiopia was delayed due to cargo flights being cut back. This showcases the dangerous impact COVID-19 can have on controlling the epidemic of locusts. Cyril Ferrand, the FAO’s Resilience Team Leader for East Africa, states access to pesticides is the biggest challenge facing their ability to control the impact of these pests.

Governments are exempting restrictions on movement for locusts control groups, recognizing their need to continue work. The FAO has stated they have been able to continue their efforts despite restriction. For instance, they have been able to treat more than 240,000 hectares with pesticides in East Africa. FAO has also trained 740 people on how to conduct ground control operations for locusts. So far, FAO has raised half of the $300 million it expects to need for pesticides.

Sustainable Farming in India

sustainable farmingHunger and food insecurity are major issues in India; the nation is home to 15 percent of the world’s undernourished people. The United Nations’ FAO estimates that every single day, more than 195 million people in India suffer from hunger.

The nation seriously lags behind other major nations like Brazil and China when it comes to crop yield for cereal and rice, which are India’s two key crops. India’s slow and inefficient agricultural sector is the result of limited access to modern technology, inefficient systems for transporting goods and urbanization. And on top of that, 63 percent of agricultural land is dependent on rainfall, so years with low rain devastate crop production. Despite all of this, farmers in India have started movements to utilize more sustainable farming methods and practices that work to make the agricultural system more efficient in order to increase outputs and improves people’s lives.

Sustainable Farming Methods

Sustainable farming practices are used to improve agricultural output and efficiency, which means that more food is produced, less resources are used and more profits are made by farmers. Examples of sustainable farming methods include using a biodegradable mulch film instead of one made from Polyethylene. While Polyethylene films require intense labor to remove, and can affect soil quality and crop growth if done improperly, biodegradable films are naturally absorbed by microorganisms in the soil, and help maintain the quality of soil while reducing costs of labor. Farmers will also use fungicides and insecticides on their seeds in order to improve the health of their crops and enhance their productivity. In addition, due to the fact that agriculture relies so heavily on rainfall, effective sustainable water management is crucial for a successful harvest.

Along with how crops are grown, how they are stored and distributed is a crucial aspect of agriculture. An estimated up to 67 million tons of food are wasted every year in India. Perishable goods end up often rotting as a result of a lack of modern technology, pests, or weather. Sustainable initiatives like using more efficient insulation and special tarpaulins that keep fruits and vegetables at proper temperatures during transportation work to reduce the number of perishables that rot. Reducing the amount of food that rots means that there is more food available to eat, which combats food insecurity and ensure that more food items are available without even increasing crop yield. And of course, combining these efforts with initiatives to produce food more sustainably and efficiently does even more to fight food insecurity.

The Natural Farming Movement

India’s Natural Farming movement plays a massive role in promoting sustainable farming practices that improve health, create jobs, cut labor costs and improve peoples’ overall quality of life. The use of pesticides has devastated farmers across India which has led to the loss of crops, debt, illness and even death. In 2000, villagers from the village of Punukula, Andrha Pradesh, launched a grassroots movement against the use of pesticides, focusing on non-pesticide management techniques that employ natural alternatives like chili pepper and planting trap crops like castor.

Within a year of the start of the movement, farmers saw pesticide-related health issues vanish, expenses drop, and profits increase. In addition, new jobs were created as a result of the need to create repellents from natural products. Villagers reported that the movement improved their quality of life — improving their financial situations, their health and their overall happiness. More villagers began to reject the use of pesticides, and the village declared itself as pesticide-free in 2004.

Zero Budget Natural Farming

A similar natural farming movement is Zero Budget Natural Farming, which began as a grassroots effort led by people in the state of Karnataka. Zero Budget entails that farmers do not spend money on inputs for their crops and that they would rather use resources from nature to grow and tend to their crops instead of chemicals, thus Zero Budget Natural Farming. Using natural products instead of taking out loans to spend on chemicals allows for farmers to save money, which improves their financial stability and allows them to focus more on tending to their crops.

A key aspect of Zero Budget Natural Farming is the use of the fermented microbial culture Jeevamrutha (a mixture of water, cow urine, cow dung, flour, soil, and brown sugar) on soil. Jeevanmrutha acts as a catalyst in promoting earthworm and microorganism activity within the soil, while also providing the soil with additional nutrients. Using natural products instead of taking out loans to spend on chemicals allows for farmers to save money, providing them with more financial stability and thus improving their quality of life.

The Zero Budget Natural Farming movement actually runs training camps that receive support by the state government. These camps last five days, with eight hours of classes per day. Attendance ranges from 300 to 5000 farmers, and topics covered include philosophy, ecology, successful farming practices, and of course, Zero Budget Natural Farming methods.

A Promising Future

The people of India suffer enormously from hunger and food insecurity. India’s weak and inefficient agricultural and food storage and distribution systems, coupled with devastating years of low rain often leads Indian farmers into bad health, hunger, and poverty. However, farmers in India have started a movement towards a more efficient, sustainable, and eco-friendly farming techniques that fight against poverty and hunger. Using these sustainable techniques means that farmers have fewer costs upfront, ensuring that they are able to make higher profits and worry less about having to take loans or to pay off debts. Sustainable farming in India reduces poverty, fights hunger, and changes lives.

Can GMOs End Global Hunger?

Can GMOs End Global Hunger?
While genetically modified (GM) foods have become a hot topic in the United States, they have received enormous attention in Africa.

At the same time that the United States has begun to debate mandatory labels for GM foods, scientists, farmers, and international organizations in Africa are pressuring governments to relax restrictions on GM technology.

This disparity in opinions towards GM crops mirrors the similar disparity of interests between the developed and developing world.

Despite the U.S.’s concern that GM crops will require more pesticides which contaminate and harm the environment, international relief organizations argue that GM crops can potentially alleviate plant diseases, the effects of climate change, and other grave threats to food production that African farmers may face.

In countries like Uganda, most people are farmers living off of their own crops and thus are more vulnerable to invasive pests and weather changes than Americans who shop in supermarkets and are more distanced from their food production.

The banana provides one example of a way that GM crops can help Uganda farmers and consumers. In the past year, “bacterial wilt disease has been cutting banana yields from 30 to 50 percent in Uganda.” When one considers that Ugandans consume up to one pound of bananas each day, it’s clear that this decrease in crop output means disastrous consequences for the Ugandans’ diet.

Recently, the National Agricultural Research Organization genetically engineered a bacteria-resistant version of the banana by breeding the fruit with pepper genes. Unless the Ugandan government passes a law that allows for use of GM crops, however, the disease-resistant banana hybrid will remain in the lab, untouched.

Though GM foods do have some clear benefits, they also come with disadvantages that prevent Ugandan farmers from fully supporting the GM law. Many Ugandans practice organic farming that rejects the use of pesticides and fertilizers because they can consequently damage other organisms like bees and fish that are important national exports.

GMOs can improve developing nations’ economies and prevent chronic hunger, but they may harm the environment and cultural traditions of these community farms in the process. This conflict of interest has many Ugandan farmers—and farmers around the world who have a stake in GM crop production—on edge, as they anxiously wait to see whether the futuristic potential of GM foods will be harnessed or rejected.
