Opis:
The value of terrestrial carbon sequestration in urban areas, due to lack of vegetation as a carbon sink, is rarely studied. In fact, urban areas have high carbon emission values, which must be minimised. On the other hand, the value of carbon sequestration in urban areas is very dynamic due to natural factors from the environment and non-natural factors from anthropogenic activities. The main objectives of this study are to identify the carbon dioxide sequestration in urban areas, especially in tropical climates, and to determine the dynamics of carbon sequestration in urban areas for a year. The results show that carbon sequestration in tropical urban areas has a significant value compared with urban areas in temperate climates. This condition happens because there are still green open spaces in gardens and agricultural lands. The value of carbon sequestration in this tropical urban area experiences monthly dynamics caused by rainfall variation and anthropogenic activities, such as land conversion and plant type conversion in agricultural lands.

Opis:
The aboveground net primary productivity (ANPP) of bofedales is one of the most important indicators for the provision of ecosystem services in the high Andean areas. In the case of bofedales, the evaluation of the ANPP supply capacity as a service on a spatial and temporal scale through remote sensing has been little addressed. The capacity, intra and interannual, to provide the ANPP of the high Andean wetlands was quantified at a spatial and temporal level through remote sensing. The normalized difference vegetation index (NDVI) of the MODIS sensor was used according to the Monteith model (1972), product of the incident photosynthetically active radiation, fraction of the absorbed radiation, and the efficiency of using the radiation of the calibrated vegetation with dry matter sampling in the field. Results show an ANPP prediction R 2 of 0.52 (p < 0.05), with no significant spatial difference between field samples. When applying the model, the intra-annual temporary ANPP supply capacity presents a maximum average of 160.54 kg DM·ha -1·month -1 in the rainy season (December-May) and a maximum average of 81.17 kg DM·ha -1·month in the dry season (June-October). In 2003-2020, the interannual temporary capacity presented values of 1100-1700 kg DM·ha -1·year -1. This makes it possible not to affect the sustainability of the wetlands and prevent their depletion and degradation. Understanding the ANPP supply capacity of bofedales can favour the efficient use of the resource and indirectly benefit its conservation.
