“…This result is in line with studies that show the land markets in Amazonia have high liquidity [41], both through direct sales and lease agreements for temporary conversion of pastures to croplands [42]. Similarly, Zaiatz et al [43] show that from 1986 to 2014, in the upper Teles Pires basin, deforested areas were first replaced by pasture and then by crops. Direct change from forest to crops was less frequent in this region.…”

Demand for agricultural exports in Brazil has stimulated the expansion of crop production and cattle raising, which has caused environmental impacts. In response, Brazil developed public policies such as the new Forest Code (FC) and supply chain arrangements such the Soy and the Cattle Moratoriums. This paper analyzes the effectiveness of these policies, considering the trajectories of agricultural expansion in the state of Mato Grosso in three years: 2005 (pre-moratorium and before the new FC), 2010 (post-moratorium and before the new FC) and 2017 (post-moratorium and post-new FC). Our analysis uses a detailed land use change data for both the Amazon and Cerrado biomes in Mato Grosso. In all the years considered, soybean expansion occurred in consolidated production areas and by conversion of pastures. Pasture expansion is influenced by existence of pastures nearby, by areas of secondary vegetation and deforestation. Our data and models show the effectiveness of public policies and private arrangements to reduce direct conversion from forests to crop production. However, our results also provide evidence that soybean expansion has caused indirect impacts by replacing pasture areas and causing pasture expansion elsewhere. Evidence from our work indicates that Brazil needs broader-ranging land use policies than what was done in the 2010s to be able to reach the land use goals stated in its Nationally Determined Contribution (NDC) to the Paris Agreement.

“…Plants growing along the coastal area roadside can dissipate the wind and wave power and reduce the impact of tropical storms and associated storm surges, maintain coastline stability and integrity and so on. Plants embedded within the urban fabric can play a crucial role in mitigating and preparing cities for the challenges of climate change [1]. In recent years, the population and urban development areas of the world's coastal cities have grown at a fast pace.…”

Although Karachi city is one of the world's fastest growing cities and considered one of the largest cities of the world, not much is known about its roadside trees. The roadside trees of different types of roads (e.g. Wide roads, Medium roads) in Karachi city of Sindhi, Pakistan were studied. Based on the field sample survey, tree species diversity of different types of roads were examined through different diversity indexes. Furthermore, the relationship between above ground biomass and biodiversity was studied by linear regression model. A total of 180 plots were surveyed, which were divided into three main types of roads. The most significant amount of tree biomass per unit area was found in Wide roads 4.27 kg/m 2 , followed by medium roads. The least biomass per unit area was found in the narrow roads, where trees biomass per unit area was 2.44 kg/m 2. A single or a small number of species dominate in the observed area that decline the species diversity. A nonnative species Conocarpus erectus revealed dominance which was followed by Guaiacum officinale on all types

“…The high species diversity in the region emphasizes the importance of conserving wetlands and vegetation types where they grow; many species have restricted habitats, as shown, for example, in the endemism levels. Conservation of the vegetation associated with watercourses is directly related to conservation of water resources, mainly in the Amazon region (Zaiatz et al 2018;Lopes et al 2020b). Despite this, over time, wetlands in Brazil have not received the economic, ecological and/ or social value that they deserve.…”

Southern Amazonia potentially harbors a wide diversity of aquatic macrophyte species because of its diverse wetland habitats and location in the Amazon-Cerrado transition zone, the two largest biogeographic domains in South America. We inventoried the taxonomic diversity of aquatic macrophytes in the region, including endemism, habitats, species life forms, and floristic comparisons with other Brazilian regions. We found a high number of species of aquatic macrophytes for the southern Amazon region, comparable to extensive inventories in larger areas in southern, northeastern, and northern regions of Brazil. We recorded 688 species of aquatic macrophytes in 299 genera and 95 families, of which 66 species are new records, 89 endemic, and 5 exclusive to Brazilian Amazonia. We present new records of aquatic macrophyte species, together with their degree of endemism and occurrence restricted to the region. The macrophyte species list of southern Amazonia showed 60% similarity to inventories in the Xingu basin and in northern Brazil. This high diversity of aquatic macrophytes in the Southern Amazonia, with endemic species and others with restricted ranges, emphasizes the importance of conserving wetlands and vegetation types where they grow in the region.
