“…The increase in vegetation coverage also played an important role in the ET increase, as it has been widely reported that revegetation has caused an increase in ET in the Loess Plateau (Feng et al, ; Li et al, ). Artificial forests, which have deep root systems, consume more deep soil moisture than cultivated crops and native grasslands in the Loess Plateau (Jia et al, ; Yang et al, ). Therefore, the increase in ET over the YRB was largely due to the increases in both LAI and irrigation water use.…”

“…There are two opposite points of view on whether an increase in vegetation (particularly forests) reduces water availability (Ellison et al, ). Some studies demonstrated that soil desiccation (Jia et al, ; Jiao et al, ; Yang et al, ) and streamflow decrease (Feng et al, ; McVicar et al, ; Zhang, Yang, McVicar, & Yang, ) occurred along with an increase in vegetation. It was also found that forest recovery induced a slight increase in streamflow because of its positive effect on both soil flow and base flow, which compensated for the reduction in surface runoff (Wang et al, ).…”

“…It was also found that forest recovery induced a slight increase in streamflow because of its positive effect on both soil flow and base flow, which compensated for the reduction in surface runoff (Wang et al, ). On the other hand, current studies have mostly focused on the effects of afforestation on runoff/streamflow (Li et al, ; McVicar et al, ; Wang et al, ) and soil moisture (Jia et al, ; Yang et al, ). However, quantitative attribution of changes in terrestrial water storage (TWS), which includes all forms of water stored above and beneath Earth's land surfaces, is essential for assessing the effects of afforestation on water availability.…”

Afforestation‐induced changes in water resources have attracted worldwide attention. However, a clear picture of quantitative attribution of terrestrial water storage (TWS) variation from hydroclimatic and anthropogenic factors is still lacking. In this study, a quantitative analysis of TWS variation was conducted in the Yellow River basin of China under the Grain for Green project with consideration of irrigation. The results showed that the TWS has decreased (increased) more and more quickly (slowly) in the Loess Plateau (headwater region). The TWS increase corresponded to increased runoff and soil moisture in the headwaters, and the TWS depletion corresponded to decreased runoff and groundwater in the Loess Plateau and downstream regions. Regarding the TWS change (TWSC), it exhibited a negative trend across the basin. The increase in evapotranspiration (ET) dominated the basin‐averaged TWSC reduction, while the increase in ET was highly related to the increases in vegetation cover and irrigation water use. For spatial TWSC variations, the value of precipitation minus ET could account for most changes in TWSC, except for those in the headwater region and a region near the internally drained area. The increased vegetation coverage, which can affect multiple hydrological processes, played an important role in these two excluded regions. Importantly, the irrigation‐induced TWSC was considerable and varied with different irrigation water sources (i.e., surface water and groundwater). Overall, the impacts of afforestation and irrigation on TWS are sufficiently important. The research in this study can provide guidance for the water resource management during revegetation efforts.

“…The population increased slowly too, suggesting that the implemented policies were succeeding in resolving regional sustainability issues, and that urban expansion had leveled off. However, in these arid areas, changes in land use or land cover can affect soil moisture, leading to fluctuations in groundwater tables [35,36]. Although the effect on soil water of land use changes brought on by afforestation have yet to be investigated within the Shiyang River Basin, many studies in other similar regions (e.g., Nosetto et al [37]; Cao et al [38]; Cao and Zhang [39]; Peng et al [40]) have suggested that afforestation can worsen water resource shortages.…”

Accounting for one quarter of China's land area, the endorheic Shiyang River basin is a vast semi-arid to arid region in China's northwest. Exploring the impact of changes in land use on this arid area's carbon budget under global warming is a key component to global climate change research. Variation in the region's soil carbon storage due to land use changes occurring between 1973 and 2012 was estimated. The results show that land use change has a significant impact on the soil carbon budget, with soil carbon storage having decreased by 3.89 Tg between 1973 and 2012. Grassland stored the greatest amount of soil carbon (114.34 Mg ha −1 ), whereas considerably lower carbon storage occurred in woodland (58.53 Mg ha −1 ), cropland (26.75 Mg ha −1 ) and unused land (13.47 Mg ha −1 ). Grasslands transformed into cropland, and woodlands degraded into grassland have substantially reduced soil carbon storage, suggesting that measures should be adopted to reverse this trend to improve soil productivity.

“…A θ é uma variável responsável pelo controle da troca de água e de energia entre a superfície terrestre e a atmosfera (JIA et al, 2017). Do ponto de vista hidrológico e ecológico, ela condiciona os processos de escoamento superficial, infiltração, armazenamento, drenagem e transpiração das plantas (ZHANG; SHAO, 2013;CHEN et al, 2014;HE et al, 2017).…”

RESUMOA umidade do solo é uma variável de grande importância para o manejo de água em cultivos agrícolas. O uso recente de irrigação em áreas de palma forrageira induz a necessidade de mensuração da umidade do solo para auxílio da tomada de decisão de quando e quanto irrigar. Logo, a estabilidade temporal e a variabilidade espacial da umidade do solo em um argissolo vermelho amarelo cultivado com palma forrageira foram avaliadas neste estudo. A pesquisa foi conduzida em Serra Talhada, PE, em um cultivo de palma forrageira com dimensões de 76 x 32 m e declividade diagonal de 0,6%, onde medidas da umidade no perfil do solo foram efetuadas em 60 posições (pontos amostrais equidistantes em 7 m), a cada 0,10 m, em seis camadas, até a profundidade de 0,60 m e em intervalos de três dias durante 41 dias. Estatística descritiva, diferença relativa da posição, matriz de correlação de Spearman e geoestatística foram aplicadas. A umidade ao longo do perfil do solo demonstrou dispersão mediana (10-20%), mesmo depois da realização de irrigação ou ocorrência de eventos de chuva. A técnica da diferença relativa da posição mostrou que a dispersão espacial da umidade do solo dependeu da camada. A matriz de correlação de Spearman detectou estabilidade temporal da umidade em todas as camadas analisadas, porém mais intensa nas maiores profundidades. A geoestatística revelou dependência entre a umidade do solo cultivado com palma e a cota da posição de medição, e estreita relação aos pontos com maior estabilidade temporal.Palavras-chave: geoestatística, irrigação, Opuntia stricta (Haw.)
