Biodiverse meadows (C1)

Biodiverse rainfed meadows improvement, installation and operation

The biodiverse rainfed meadow has the following advantages in view of the expected impacts to climate change:

  • The high number of species used in this type of pasture (rich in Poaceae species, also known as grasses) guarantees greater variability, increasing the survival rate and, therefore, maintaining the ecosystem;
  • Provides a wide range of ecosystem services, such as soil conservation due to its root system;
  • In addition to climate change adaptation, these ecosystems also contribute to the mitigation of climate change, including carbon sequestration;
  • In cities, it is an important tool for reducing water consumption and acting as a valid alternative for demanding irrigation lawns, while simultaneously having high rates of CO2 and NO2 uptake in the soil;
  • It contributes to a more stable soil composition, with positive results in water retention, acting as a sponge structure.

It involves two sub-actions:

  • 2,6 ha of converted biodiverse rainfed meadow (Bela Vista)

The objective is the enrichment of rainfed pastures in Parque da Bela Vista, which are currently not rich in grasses (Poaceae).

This sub-action started during the fall of 2019, after the first rains, in order to guarantee the success of sowing and seed production.

  • 8 ha of biodiverse sown dryland meadow (Bela Vista and Alto da Ajuda)

This sub-action targets the ruderal pastures in Parque da Bela Vista and Alto da Ajuda.

This sub-action starts during the fall of 2020, after the first rains, in order to guarantee the success of sowing and seed production.

In these areas, intervention in the second year is necessary, covering a second sowing and direct fertilization.

In the case of the area at Parque da Bela Vista, the installation and sustainability of this ecosystem in high pressure areas is also tested, as it is in this area that the “Rock in Rio” event usually takes place every 2 years. 

Timeframe: start of sowing in October 2019 and is expected to end in December 2021.
