“…The Northeast Region of Brazil (NEB), characterized as a semiarid region, presents scarce rainfall and is frequently affected by long periods of drought [1,2]. The annual accumulated precipitation does not exceed 500 mm in some areas of the semiarid Northeast; in contrast, there are areas like the coastland of the NEB where the annual rainfall is more than 1500 mm [3][4][5][6].…”

This study aims to analyze the climatological classification of precipitating clouds in the Northeast of Brazil using the radar on board the Tropical Rainfall Measuring Mission (TRMM) satellite. Thus, for this research a time series of 15 years of satellite data (period 1998-2012) was analyzed in order to identify what types of clouds produce precipitation estimated by Precipitation Radar (PR) and how often these clouds occur. From the results of this work it was possible to estimate the average relative frequency of each type of cloud present in weather systems that influence the Northeast of Brazil. In general, the stratiform clouds and shallow convective clouds are the most frequent in this region, but the associated rainfall is not as abundant as precipitation caused by deep convective clouds. It is also seen that a strong signal of shallow convective clouds modulates rainfall over the coastal areas of Northeast of Brazil and adjacent ocean. In this scenario, the main objective of this study is to contribute to a better understanding of the patterns of cloud types associated with precipitation and building a climatological analysis from the classification of clouds.

“…Vegetation regeneration is a strong indicator of changes in soil conditions and an increase in soil temperature will have an adverse effect on vegetation regeneration levels (Althoff et al, 2016). Similarly, root biomass may change in response to altered environmental variables (Norby and Jackson, 2000).…”

“…Although warming affects all plant life-cycle phases, plant regeneration has been suggested to be especially sensitive ( Hedhly et al, 2009 ; Walck et al, 2011 ). Vegetation regeneration is a strong indicator of changes in soil conditions and an increase in soil temperature will have an adverse effect on vegetation regeneration levels ( Althoff et al, 2016 ). Similarly, root biomass may change in response to altered environmental variables ( Norby and Jackson, 2000 ).…”

Temperature Effects on Biomass and Regeneration of Vegetation in a Geothermal Area

et al. 2017

Understanding the effects of increasing temperature is central in explaining the effects of climate change on vegetation. Here, we investigate how warming affects vegetation regeneration and root biomass and if there is an interactive effect of warming with other environmental variables. We also examine if geothermal warming effects on vegetation regeneration and root biomass can be used in climate change experiments. Monitoring plots were arranged in a grid across the study area to cover a range of soil temperatures. The plots were cleared of vegetation and root-free ingrowth cores were installed to assess above and below-ground regeneration rates. Temperature sensors were buried in the plots for continued soil temperature monitoring. Soil moisture, pH, and soil chemistry of the plots were also recorded. Data were analyzed using least absolute shrinkage and selection operator and linear regression to identify the environmental variable with the greatest influence on vegetation regeneration and root biomass. There was lower root biomass and slower vegetation regeneration in high temperature plots. Soil temperature was positively correlated with soil moisture and negatively correlated with soil pH. Iron and sulfate were present in the soil in the highest quantities compared to other measured soil chemicals and had a strong positive relationship with soil temperature. Our findings suggest that soil temperature had a major impact on root biomass and vegetation regeneration. In geothermal fields, vegetation establishment and growth can be restricted by low soil moisture, low soil pH, and an imbalance in soil chemistry. The correlation between soil moisture, pH, chemistry, and plant regeneration was chiefly driven by soil temperature. Soil temperature was negatively correlated to the distance from the geothermal features. Apart from characterizing plant regeneration on geothermal soils, this study further demonstrates a novel approach to global warming experiments, which could be particularly useful in low heat flow geothermal systems that more realistically mimic soil warming.

“…However, there are potential problems in the harvesting of this species in flooded areas, due to climate change (Herraiz et al 2017). Climate changes can also compromise harvesting in other biomes, such as for firewood harvesting in Caatinga (Althoff et al 2016).…”

Indigenous and traditional knowledge, sustainable harvest, and the long road ahead to reach the 2020 Global Strategy for Plant Conservation objectives

et al. 2018

Global strategies under the scope of CBD are important in guiding policies and resources for the conservation of biological diversity. This paper emphasized the need to develop actions under the Global Strategy for Plant Conservation (GSPC) with measurable results up to 2020, regarding the status and perspectives related to Targets 12 and 13, focusing on the Brazilian context in order to identify gaps and actions to achieve the goals for conservation and sustainable use of plants. It should be noted that Target 12 also covers logging, not necessarily directly related to indigenous peoples and traditional communities, but may threaten their livelihoods. In Brazil, scientific knowledge about the ecological effects of the harvesting of non-timber forest products is still limited, and few studies have contributed to the establishment of legal regulations for collection and management. With regard to target 13, which concerns traditional and indigenous knowledge about plant use and the dependence of these peoples on plants, there are still a lack of integrative and effective policy initiatives. However, considering the negative political context of recent decades and exacerbated in recent years in relation to biodiversity conservation and indigenous peoples and local communities, profound changes are necessary in the Brazilian scenario, with strong support and recognition for indigenous peoples and local communities, so that any objective related to the achievement of the goals of the GSPC is minimally achieved.
