“…Nine ecosystem service functions proposed by Xie et al (2008) were selected to calculate the total ESV in Central Asia (Table 1), which could mask the value of other key ecosystem service functions. For example, sand fixation is an important function provided by desert ecosystems in arid and semi-arid areas, which has a close relationship with ecological benefits (Li & Xu, 2019; Musa, Deming & Cunyang, 2014; Taylor et al, 2017). Hao et al (2013) found that the ESV of sand fixation in the Ulan Buh desert ecosystem was 0.68 billion US$ in 2009.…”

Acute farmland expansion and rapid urbanization in Central Asia have accelerated land use/land cover changes, which have substantial effects on ecosystem services. However, the spatiotemporal variations in ecosystem service values (ESVs) in Central Asia are not well understood. Here, based on land use products with 300-m resolution for the years 1995, 2005 and 2015 and transfer methodology, we predicted land use and land cover (LULC) for 2025 and 2035 using CA-Markov, assessed changes in ESVs in response to LULC dynamics, and explored the elasticity of the response of ESV to LULC changes. We found significant expansions of cropland (+22.10%) and urban areas (+322.40%) and shrinking of water bodies (−38.43%) and bare land (−9.42%) during 1995–2035. The combined value of ecosystem services of water bodies, cropland, and grassland accounted for over 90% of the total ESVs. Our study showed that cropland ecosystem services value increased by 93.45 billion US$ from 1995 to 2035, which was mainly caused by the expansion of cropland area. However, the area of water bodies decreased sharply during 1995–2035, causing a loss of 64.38 billion US$. Biodiversity, food production and water regulation were major ecosystem service functions, accounting for 80.52% of the total ESVs. Our results demonstrated that effective land-use policies should be made to control farmland expansion and protect water bodies, grassland and forestland for more sustainable ecosystem services.

“…identificar las variables bioclimáticas que determinan and the Sonoran Desert. The first region is the biome with the largest extension and includes 16 states of the Mexican Republic (Taylor, Davis, Abad, McClung & Moran, 2017); the second is located in the states of Puebla and Oaxaca, which contains 10 to 11.4 % of the country's flora (Dávila et al, 2002); and the third included the Baja California Peninsula. The three regions have dry and semi-dry climates and have records of the presence of the species in question (Figure 1).…”

El conocimiento de la distribución de las especies en relación con las condiciones bióticas y abióticas permite conocer las posibles respuestas de las especies a los cambios, ubicar la presencia geográfica de especies de importancia comercial. Los objetivos fueron Identificar las variables bioclimáticas que determinan la distribución de poblaciones de E. antisyphilitica y estimar la distribución potencial de la especie en las zonas áridas usando dos métodos Maxent y Bioclim. Los datos de presencia fueron del inventario nacional de E. antisyphilitica y se usaron 19 capas climáticas de Worldclim con una resolución espacial de l km2 . Se procesaron con el método de máxima entropía además los requerimientos de temperatura y precipitación se analizaron con la comparación de variables bioclimáticas, la predicción de la modelación de la distribución y la salida geográfica u Las variables de precipitación influyen más que las de temperatura sobre la distribución de E. antisyphilitica, en un intervalo de precipitación de 200 a 500 mm. La modelación y salida geográfica usando BIoclim de Diva-Gis 7.5® y Maxent® -3.4.1. Las variables de precipitación contribuyeron con el 67.7 % y las variables de temperatura aportaron 32.4%, por lo tanto, en la distribución de E. antisyphilitica, donde la precipitación es el principal factor que inflluye en la presencia de la especie seguida de las variables de temperatura. Maxent es mejor modelo que Bioclim de Diva-Gis para determinar la superficie potencial que ocupa E. antisyphilitica y permite obtener imágenes de calidad con resolución mayor, esto representa una ventaja para estimar las áreas de distribución de poblaciones de candelilla.

“…As a result, the harvest of A. lechuguilla for fiber extraction has become a managed practice that can be considered sustainable [ 4 , 11 ]. The annual production of fiber is concentrated in six states of Mexico (San Luis Potosí, Coahuila, Nuevo León, Zacatecas, Durango, and Tamaulipas) and reaches around 55.98 kg/ha [ 12 ]. However, the manual or mechanical shredding of the leaves results in material consisting of 15% fiber ( ixtle ) and 85% wasted plant residue ( guishe ), representing over 150 thousand tons of residual biomass each year [ 2 , 13 ].…”

Agave lechuguilla waste biomass (guishe) is an undervalued abundant plant material with natural active compounds such as flavonoids. Hence, the search and conservation of flavonoids through the different productive areas have to be studied to promote the use of this agro-residue for industrial purposes. In this work, we compared the proportion of total flavonoid content (TFC) among the total polyphenolics (TPC) and described the variation of specific flavonoid profiles (HPLC-UV-MS/MS) of guishe from three locations. Descriptive environmental analysis, using remote sensing, was used to understand the phytochemical variability among the productive regions. Furthermore, the effect of extractive solvent (ethanol and methanol) and storage conditions on specific flavonoid recovery were evaluated. The highest TPC (16.46 ± 1.09 GAE/g) was observed in the guishe from region 1, which also had a lower normalized difference water index (NDWI) and lower normalized difference vegetation index (NDVI). In contrast, the TFC was similar in the agro-residue from the three studied areas, suggesting that TFC is not affected by the studied environmental features. The highest TFC was found in the ethanolic extracts (6.32 ± 1.66 QE/g) compared to the methanolic extracts (3.81 ± 1.14 QE/g). Additionally, the highest diversity in flavonoids was found in the ethanolic extract of guishe from region 3, which presented an intermedia NDWI and a lower NDVI. Despite the geo-climatic induced variations of the phytochemical profiles, the results confirm that guishe is a valuable raw material in terms of its flavonoid-enriched bioactive extracts. Additionally, the bioactive flavonoids remain stable when the conditioned agro-residue was hermetically stored at room temperature in the dark for nine months. Finally, the results enabled the establishment of both agro-ecological and biotechnological implications.
