Djibouti's Sources of N2O Emissions

✨ Key Insights

Agricultural Emissions Dominate

Djibouti's N2O emissions have been predominantly driven by agriculture, with a significant increase observed over the decades. From the mid-20th century, agricultural emissions have consistently been the largest contributor to the country's N2O emissions. This trend aligns with the country's efforts to develop its agricultural sector post-independence in 1977, which likely led to increased use of fertilizers and other agricultural practices contributing to N2O emissions.

Energy and Waste Contributions

While agriculture remains the primary source, emissions from energy and waste sectors have also shown notable trends. The energy sector saw a gradual increase in emissions, particularly from the 1980s onwards, coinciding with infrastructure developments like the Port of Djibouti expansion in 1985. Waste emissions, although smaller in magnitude, have steadily increased, reflecting urbanization and population growth.

Recent Efforts and Future Outlook

In recent years, Djibouti has taken steps to address its emissions through renewable energy projects and initiatives like the Green Port Initiative launched in 2022. These efforts aim to reduce reliance on fossil fuels and lower emissions from key sectors. The country's updated Climate Action Plan in 2023 underscores its commitment to sustainable development, potentially leading to a more balanced emissions profile in the future.

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.
