Sri Lanka’s decision to ban imports on chemical fertilizers was not backed by scientific evidence
There is consensus in the scientific community that organic agriculture could reduce crop yield. Quoting three global meta-data analysis, Meemkem and Qaim (2018) pointed out that on average, the yield reduction in organic agricultural systems could be 19-25%, depending on the crop and agro-climatic region. To switch to 100% organic agriculture, a country must have robust scientific evidence and a meticulously planned methodology along with targeted actions. Otherwise, it will plunge into a food crisis, if food security cannot be achieved by other means.
Organic agriculture is often perceived as more sustainable than conventional farming. In terms of environmental and climate change effects, organic farming is less polluting than conventional farming when measured per unit of land but not when measured per unit of output.
Organic farming, which currently accounts for only 1% of global agricultural land, is lower yielding on average. Due to higher knowledge requirements, observed yield gaps might further increase if a larger number of farmers would switch to organic practices.
Widespread upscaling of organic agriculture would cause additional loss of natural habitats and also entail output price increases, making food less affordable for poor consumers in developing countries.
Organic farming is not the paradigm for sustainable agriculture and food security, but smart combinations of organic and conventional methods could contribute toward sustainable productivity increases in global agriculture.
Organic mania
In May, Sri Lankan President Gotabaya Rajapaksa ordered a halt to importing chemical fertilizers to turn the island nation’s agriculture sector fully organic.
By that time, the Yala cropping season (May to August) had already started and farmers were using the agro-chemicals available in the market. However, no additional agro-chemicals were to be released in the market.
The government stated that if there is any yield loss as a consequence of this decision, the affected farmers would be compensated for it. It is unclear how the government was planning to separate yield loss related to lack of agro-chemicals from yield loss due to natural causes, farmers’ attitudes, and so on.
It is apparent now that when the Sri Lankan government took this policy decision, it had neither solid scientific information nor a clear action plan. It had taken half-baked advice from some opportunists who regularly state in public that only organic and traditional agriculture is safe to the environment and human beings.
Sri Lanka has been almost entirely reliant on its own rice production since the mid-2000s. Could it not have maintained this?
Unsurprisingly, even when the Maha season officially started on October 15, the country was well short of the required quantities of organic fertilizers.
As the most critical plant nutrient for higher yields in Sri Lanka is nitrogen (N), the authorities have estimated that for this Maha season, about 0.1 million tonnes of N is required for some major crops including paddy and tea.
This is equivalent to about 15 million tonnes of compost. The country produced only around 3 million tonnes of compost by the end of August 2021.
Realising that the required quantities of organic fertilizers cannot be produced within five months, the government attempted in September to import solid organic fertilizers.
According to the Plant Protection Act, No. 35 of 1999, no organic substance that has harmful organisms can be imported into the country. Moreover, Sri Lanka Standards (SLSI 1704) require all imported solid organic fertilizer to be devoid of any micro-organism.
A tender to supply about 0.1 million tonnes of solid organic fertilizer was offered to a Chinese fertilizer company. It was later revealed that two samples provided by this company did not pass the quality standards.
This message was conveyed by the authorities to the company. However, due to reasons unknown, the first load of that solid organic fertilizer is said to have come to Sri Lankan waters and is sailing around still looking for an opportunity to reach the shores of Sri Lanka.
Meanwhile, farmers started getting angry as there were no fertilizers to start cultivation. They began to protest, demanding fertilizers to be provided in all major agricultural areas and setting aside preliminary land preparation practices. They did not want to start commercial cultivation without any assurance from the government on the availability of the required fertilizers.Then, the government was advised to purchase a liquid nano-N fertilizer from the Indian Farmer Fertilizer Corporative Limited (IFFCO), which, some said, is organic and 100% efficient.
However, according to the IFFCO website, this liquid fertilizer is actually nano-urea and hence cannot be used in organic agriculture as it is chemical in nature. Given the urgency of the situation, the government ordered 3.1 million litres of nano-urea, which has only 4% N, from IFFCO.
The first quantity was air-lifted into Sri Lanka and distributed as Nano-Raja among paddy farmers. Farmers were advised to apply 2.5 L of Nano-Raja as a foliar spray.
Scientists are sceptical about the efficacy of this fertilizer as there has been heavy rainfall in Sri Lanka over the last few weeks. Nonetheless, even in India, there is limited large-scale evidence on the effectiveness of this product. Not much is known about the health concerns that might arise on long-term exposure to nano-particles.
Moreover, 2.5 L of Nano-Raja provides only 100g of N when at least 50kg of N is needed for the paddy crop. The farmers will at most get an additional 5-10kg of N through locally available compost. The quality of these composts, mostly produced using municipal solid wastes, cannot be guaranteed either, as there is no quality control mechanism in place.
Crop decline
Now, even over a month after the season started, only about 25-40% of farmers have started paddy cultivation in Sri Lanka. The distributed quantities of N fertilizers have not been adequate to achieve the expected yield target of the farmers (4-6 tonnes per hectare).
Therefore, reduction in national paddy production is an inevitability. The same would be true for other crop sectors as well. Therefore, the government must do something within a very short period of time to provide sufficient quantities of N fertilizer, at least to paddy farmers and tea-growers.
Failure to do so will reduce foreign exchange earnings from tea, increase food prices, create food shortage and lead to food imports. The government will have to import food from other countries — food that is produced using agro-chemicals because of the higher price of organic food. This would be ironical as food without agro-chemicals was one of the major policy objectives of the ban on the import of agro-chemicals.
The overarching policy document of the government titled ‘Vistas of Prosperity and Splendor’ promises to provide the nation with safe food and food security. However, the ill-advised policy of banning agro-chemicals, which was based on inadequate scientific evidence and false belief, hit the Sri Lankan agriculture and plantation crop sectors like a cyclone.
With a crippling economy thanks to COVID-19, this was uncalled for. On November 24, the Sri Lankan government announced that it would partially lift the ban on chemical fertilizers and permit the private sector to import these fertilizers. However, considerable damage has already been done, with farmers claiming that their crop production has declined, food prices rising, and a food crisis looming.

The United Nations has shaped so much of global co-operation and regulation that we wouldn’t recognise our world today without the UN’s pervasive role in it. So many small details of our lives – such as postage and copyright laws – are subject to international co-operation nurtured by the UN.
In its 75th year, however, the UN is in a difficult moment as the world faces climate crisis, a global pandemic, great power competition, trade wars, economic depression and a wider breakdown in international co-operation.

Still, the UN has faced tough times before – over many decades during the Cold War, the Security Council was crippled by deep tensions between the US and the Soviet Union. The UN is not as sidelined or divided today as it was then. However, as the relationship between China and the US sours, the achievements of global co-operation are being eroded.
The way in which people speak about the UN often implies a level of coherence and bureaucratic independence that the UN rarely possesses. A failure of the UN is normally better understood as a failure of international co-operation.
We see this recently in the UN’s inability to deal with crises from the ethnic cleansing of the Rohingya Muslims in Myanmar, to civil conflict in Syria, and the failure of the Security Council to adopt a COVID-19 resolution calling for ceasefires in conflict zones and a co-operative international response to the pandemic.
The UN administration is not primarily to blame for these failures; rather, the problem is the great powers – in the case of COVID-19, China and the US – refusing to co-operate.
Where states fail to agree, the UN is powerless to act.
Marking the 75th anniversary of the official formation of the UN, when 50 founding nations signed the UN Charter on June 26, 1945, we look at some of its key triumphs and resounding failures.
Five successes
1. Peacekeeping
The United Nations was created with the goal of being a collective security organisation. The UN Charter establishes that the use of force is only lawful either in self-defence or if authorised by the UN Security Council. The Security Council’s five permanent members, being China, US, UK, Russia and France, can veto any such resolution.
The UN’s consistent role in seeking to manage conflict is one of its greatest successes.
A key component of this role is peacekeeping. The UN under its second secretary-general, the Swedish statesman Dag Hammarskjöld – who was posthumously awarded the Nobel Peace prize after he died in a suspicious plane crash – created the concept of peacekeeping. Hammarskjöld was responding to the 1956 Suez Crisis, in which the US opposed the invasion of Egypt by its allies Israel, France and the UK.
UN peacekeeping missions involve the use of impartial and armed UN forces, drawn from member states, to stabilise fragile situations. “The essence of peacekeeping is the use of soldiers as a catalyst for peace rather than as the instruments of war,” said then UN Secretary-General Javier Pérez de Cuéllar, when the forces won the 1988 Nobel Peace Prize following missions in conflict zones in the Middle East, Africa, Asia, Central America and Europe.
However, peacekeeping also counts among the UN’s major failures.
2. Law of the Sea
Negotiated between 1973 and 1982, the UN Convention on the Law of the Sea (UNCLOS) set up the current international law of the seas. It defines states’ rights and creates concepts such as exclusive economic zones, as well as procedures for the settling of disputes, new arrangements for governing deep sea bed mining, and importantly, new provisions for the protection of marine resources and ocean conservation.
Mostly, countries have abided by the convention. There are various disputes that China has over the East and South China Seas which present a conflict between power and law, in that although UNCLOS creates mechanisms for resolving disputes, a powerful state isn’t necessarily going to submit to those mechanisms.
Secondly, on the conservation front, although UNCLOS is a huge step forward, it has failed to adequately protect oceans that are outside any state’s control. Ocean ecosystems have been dramatically transformed through overfishing. This is an ecological catastrophe that UNCLOS has slowed, but failed to address comprehensively.
3. Decolonisation
The idea of racial equality and of a people’s right to self-determination was discussed in the wake of World War I and rejected. After World War II, however, those principles were endorsed within the UN system, and the Trusteeship Council, which monitored the process of decolonisation, was one of the initial bodies of the UN.
Although many national independence movements only won liberation through bloody conflicts, the UN has overseen a process of decolonisation that has transformed international politics. In 1945, around one third of the world’s population lived under colonial rule. Today, there are less than 2 million people living in colonies.
When it comes to the world’s First Nations, however, the UN generally has done little to address their concerns, aside from the non-binding UN Declaration on the Rights of Indigenous Peoples of 2007.
4. Human rights
The Human Rights Declaration of 1948 for the first time set out fundamental human rights to be universally protected, recognising that the “inherent dignity and of the equal and inalienable rights of all members of the human family is the foundation of freedom, justice and peace in the world”.
Since 1948, 10 human rights treaties have been adopted – including conventions on the rights of children and migrant workers, and against torture and discrimination based on gender and race – each monitored by its own committee of independent experts.
The language of human rights has created a new framework for thinking about the relationship between the individual, the state and the international system. Although some people would prefer that political movements focus on ‘liberation’ rather than ‘rights’, the idea of human rights has made the individual person a focus of national and international attention.
5. Free trade
Depending on your politics, you might view the World Trade Organisation as a huge success, or a huge failure.
The WTO creates a near-binding system of international trade law with a clear and efficient dispute resolution process.
The majority Australian consensus is that the WTO is a success because it has been good for Australian famers especially, through its winding back of subsidies and tariffs.
However, the WTO enabled an era of globalisation which is now politically controversial.
Recently, the US has sought to disrupt the system. In addition to the trade war with China, the Trump Administration has also refused to appoint tribunal members to the WTO’s Appellate Body, so it has crippled the dispute resolution process. Of course, the Trump Administration is not the first to take issue with China’s trade strategies, which include subsidises for ‘State Owned Enterprises’ and demands that foreign firms transfer intellectual property in exchange for market access.
The existence of the UN has created a forum where nations can discuss new problems, and climate change is one of them. The Intergovernmental Panel on Climate Change (IPCC) was set up in 1988 to assess climate science and provide policymakers with assessments and options. In 1992, the UN Framework Convention on Climate Change created a permanent forum for negotiations.
However, despite an international scientific body in the IPCC, and 165 signatory nations to the climate treaty, global greenhouse gas emissions have continued to increase.
Under the Paris Agreement, even if every country meets its greenhouse gas emission targets we are still on track for ‘dangerous warming’. Yet, no major country is even on track to meet its targets; while emissions will probably decline this year as a result of COVID-19, atmospheric concentrations of greenhouse gases will still increase.
This illustrates a core conundrum of the UN in that it opens the possibility of global cooperation, but is unable to constrain states from pursuing their narrowly conceived self-interests. Deep co-operation remains challenging.
Five failures of the UN
1. Peacekeeping
During the Bosnian War, Dutch peacekeeping forces stationed in the town of Srebrenica, declared a ‘safe area’ by the UN in 1993, failed in 1995 to stop the massacre of more than 8000 Muslim men and boys by Bosnian Serb forces. This is one of the most widely discussed examples of the failures of international peacekeeping operations.
On the massacre’s 10th anniversary, then UN Secretary General Kofi Annan wrote that the UN had “made serious errors of judgement, rooted in a philosophy of impartiality”, contributing to a mass murder that would “haunt our history forever”.
If you look at some of the other infamous failures of peacekeeping missions – in places such as Rwanda, Somalia and Angola – it is the limited powers given to peacekeeping operations that have resulted in those failures.
2. The invasion of Iraq
The invasion of Iraq by the US in 2003, which was unlawful and without Security Council authorisation, reflects the fact that the UN is has very limited capacity to constrain the actions of great powers.
The Security Council designers created the veto power so that any of the five permanent members could reject a Council resolution, so in that way it is programmed to fail when a great power really wants to do something that the international community generally condemns.
In the case of the Iraq invasion, the US didn’t veto a resolution, but rather sought authorisation that it did not get. The UN, if you go by the idea of collective security, should have responded by defending Iraq against this unlawful use of force.
The invasion proved a humanitarian disaster with the loss of more than 400,000 lives, and many believe that it led to the emergence of the terrorist Islamic State.
3. Refugee crises
The UN brokered the 1951 Refugee Convention to address the plight of people displaced in Europe due to World War II; years later, the 1967 Protocol removed time and geographical restrictions so that the Convention can now apply universally (although many countries in Asia have refused to sign it, owing in part to its Eurocentric origins).
Despite these treaties, and the work of the UN High Commission for Refugees, there is somewhere between 30 and 40 million refugees, many of them, such as many Palestinians, living for decades outside their homelands. This is in addition to more than 40 million people displaced within their own countries.
While for a long time refugee numbers were reducing, in recent years, particularly driven by the Syrian conflict, there have been increases in the number of people being displaced.
During the COVID-19 crisis, boatloads of Rohingya refugees were turned away by port after port. This tragedy has echoes of pre-World War II when ships of Jewish refugees fleeing Nazi Germany were refused entry by multiple countries.
And as a catastrophe of a different kind looms, there is no international framework in place for responding to people who will be displaced by rising seas and other effects of climate change.
4. Conflicts without end
Across the world, there is a shopping list of unresolved civil conflicts and disputed territories.
Palestine and Kashmir are two of the longest-running failures of the UN to resolve disputed lands. More recent, ongoing conflicts include the civil wars in Syria and Yemen.
The common denominator of unresolved conflicts is either division among the great powers, or a lack of international interest due to the geopolitical stakes not being sufficiently high. For instance, the inaction during the Rwandan civil war in the 1990s was not due to a division among great powers, but rather a lack of political will to engage.
In Syria, by contrast, Russia and the US have opposing interests and back opposing sides: Russia backs the government of the Syrian dictator Bashar al-Assad, whereas the US does not.
5. Acting like it’s 1945
The UN is increasingly out of step with the reality of geopolitics today.
The permanent members of the Security Council reflect the division of power internationally at the end of World War II. The continuing exclusion of Germany, Japan, and rising powers such as India and Indonesia, reflects the failure to reflect the changing balance of power.
Also, bodies such as the IMF and the World Bank, which are part of the UN system, continue to be dominated by the West. In response, China has created potential rival institutions such as the Asian Infrastructure Investment Bank.
Western domination of UN institutions undermines their credibility. However, a more fundamental problem is that institutions designed in 1945 are a poor fit with the systemic global challenges – of which climate change is foremost – that we face today.
