Haiti's Sources of N2O Emissions

✨ Key Insights

Agricultural Emissions Dominate

Haiti's N2O emissions have been predominantly driven by agriculture, which has consistently been the largest contributor over the decades. The data shows a significant increase in agricultural emissions from the mid-20th century, peaking around the 2000s. This trend aligns with the country's reliance on agriculture for economic sustenance, despite challenges such as deforestation and land degradation. Notably, the year 2000 saw a substantial spike in agricultural emissions, reflecting intensified agricultural activities.

Energy and Waste Contributions

While agriculture remains the primary source, emissions from energy and waste sectors have also shown gradual increases. The energy sector, although smaller in scale, has seen a steady rise in emissions, likely due to increased fossil fuel use for transportation and energy needs. Waste emissions have similarly grown, albeit at a slower pace, indicating challenges in waste management practices. These sectors, while not as dominant as agriculture, contribute to the overall emissions profile of Haiti.

Impact of Natural Disasters

Haiti's vulnerability to natural disasters has had a notable impact on its emissions. Events such as the 2010 earthquake and multiple hurricanes have led to deforestation and land-use changes, exacerbating emissions. The destruction of vegetation and infrastructure necessitated reconstruction efforts, which further increased emissions. These events highlight the complex interplay between natural disasters and anthropogenic emissions, underscoring the need for sustainable recovery strategies.

Background

The chart shows a national breakdown by source of the yearly nitrous oxide (N2O) emissions from human activities and processes, expressed as weight in megatonnes (Mt). Human-induced emissions are the main driver of the increasing atmospheric nitrous oxide that is warming our planet. The sources of human nitrous oxide emissions are

  • Agriculture
  • Energy
  • Industry
  • Waste
  • Other

Agriculture

Emissions related to agriculture are mainly from the use of synthetic fertilizers and manure management.


Synthetic fertilizer, used for agricultural processes, contains a lot of nitrogen. That nitrogen in the soil reacts and causes considerable N2O emissions. The use of excess fertilizer, meaning more fertilizer than the plants can use to grow, causes even higher relative emissions. Applying the right amount of fertilizer at the right time can reduce N2O emissions. There are many technical solutions to reduce emissions while keeping, or even increasing, agricultural yields.


When manure is left on the field or otherwise managed in dry processes, it emits considerable amounts of nitrous oxide. Manure can be managed by wet processes, which reduces nitrous oxide emissions but increases methane emissions. Some technical solutions focus on modifying the animal feed to reduce the nitrogen in the manure, thereby reducing nitrous oxide emissions.

Energy, Industry, Waste, and Other

All non-agricultural categories together have much lower emissions than agricultural emissions alone.


N2O emissions related to energy are almost all from the combustion of fossil fuels. For example, the combustion of fossil fuels in power plants, cars, and airplanes not only causes CO2 emissions but also emits nitrous oxide (N2O). Any advances to reducing fossil fuel dependency will thus also reduce nitrous oxide emissions.


Most industry-related emissions are from the chemical industry for producing fertilizer, nylon, and similar products. Technologies are available to reduce emissions in these processes.

Nitrous oxide emissions from waste come from, for example, wastewater treatment and landfills.

Units and Measures

N2O emissions are expressed in the total weight in megatonnes per year. 1 Megatonne is equal to 1 million tonnes.

About the Data

The last available year in all the emission datasets is 2023. N2O emissions come from the PRIMAP-Hist dataset. It is a rich dataset that combines several published sources to create a historical emissions time series for various greenhouse gases.

The Key Insights paragraph was generated using a large language model (LLM) using a structured approach to improve the accuracy. This included separating the context generation from the interpretation and narrative.
