Spatial Differentiation of Cultivated Land Use Intensification in Village Settings: A Survey of Typical Chinese Villages

The intensified use of cultivated land is essential for optimizing crop planting practices and protecting food security. This study employed a telecoupling framework to evaluate the cultivated land use intensification rates in typical Chinese villages (village cultivated land use intensifications—VCLUIs). The pressure–state–response (PSR) model organizes the VCLUI indexes including the intensity press, output state, and structural response of cultivated land use. Empirical analysis conducted in Baiquan County, China, indicating that the cultivated land use intensification levels of the whole county were low. However, the intensifications of villages influenced by physical and geographic locations and socioeconomic development levels varied significantly. This paper also found that variations in the VCLUIs were mainly dependent on new labor-driven social subsystem differences. Thus, the expanding per capita farmland scales and increasing numbers of new agricultural business entities were critical in improving the VCLUI. Overall, the theoretical framework proposed in this study was demonstrated to be effective in analyzing interactions among the natural, social, and economic subsystems of the VCLUI. The findings obtained in this study potentially have important implications for future regional food security, natural stability, and agricultural land use sustainability.

AbstractDespite their restriction, smallholder farmers have been continuing growing Eucalyptus globulus in the cultivated land in the central highland of Ethiopia. Literature has shown controversial issues against E. globulus. Therefore, the objective of the study was to investigate the compatibility of E. globulus in the smallholder farmers’ land use system. Soil samples were collected from five different land uses and analysed for selected physical and chemical properties. The socioeconomic contribution of E. globulus was collected through household surveys from 110 households. Analysis of soil showed that organic carbon (OC), total nitrogen (TN) and cation exchange capacity (CEC) were significantly higher (P<0.05) under E. globulus compared to the cultivated land. The survey results also showed that the largest proportion (58%) of households was interested in growing E. globulus because of its multiple uses. About 83% of households responded that E. globulus help them to attain food security through increasing the purchasing power of smallholder farmers to buy agricultural inputs and food. This study has substantiated the role of E. globulus in the land use system of smallholder farmers. Most of the soil fertility indicators were better under E. globulus. The present finding reveals that E. globulus degrade the soil seemingly difficult to generalise. Growing E. globulus must be promoted under appealing land use to enhance smallholder farmers’ livelihoods. Removing E. globulus from the land use system may jeopardise the food security situation of many households.

Groundwater Level Changes

The long-term overexploitation of groundwater leads to serious land subsidence and threatens the safety of Beijing-Tianjin-Hebei (BTH). In this paper, an interferometric point target analysis (IPTA) with small baseline subset InSAR (SBAS-InSAR) technique was used to derive the land subsidence in a typical BTH area from 2012 to 2018 with 126 Radarsat-2 and 184 Sentinel-1 images. The analysis reveals that the average subsidence rate reached 118 mm/year from 2012 to 2018. Eleven subsidence features were identified: Shangzhuang, Beijing Airport, Jinzhan and Heizhuanghu in Beijing, Guangyang and Shengfang in Langfang, Wangqingtuo in Tianjin, Dongguang in Cangzhou, Jingxian and Zaoqiang in Hengshui and Julu in Xingtai. Comparing the different types of land use in subsidence feature areas, the results show that when the land-use type is relatively more complex and superimposed with residential, industrial and agricultural land, the land subsidence is relatively more significant. Moreover, the land subsidence development patterns are different in the BTH areas because of the different methods adopted for their water resource development and utilization, with an imbalance in their economic development levels. Finally, we found that the subsidence changes are consistent with groundwater level changes and there is a lag period between land subsidence and groundwater level changes of approximately two months in Beijing Airport, Jinzhan, Jingxian and Zaoqiang, of three months in Shangzhuang, Heizhuanghu, Guangyang, Wangqingtuo and Dongguang and of four months in Shengfang.

The Impact

Undistorted factor markets are a perquisite for efficient allocation of resources and growth in production. In Oman by 2013, only 16% of households have reported agriculture as the main occupation and 53% have reported nonagricultural government employment as the main occupation. This situation is hypothesized to be related to the labor market; where government legislated higher remuneration in the nonagricultural government sector vis-a-vis agricultural sector, influences Omani farmers to move to nonagricultural employment, causing reduced cultivated area and farm production. The study uses operations research methods to quantify the impact of labor market policies on agricultural employment, farm gross income and land use intensity (proxy for farm production and food security). It is found that the shift of Omani labor from agriculture is influenced by higher wages in the nonagricultural sectors. The agricultural land use intensity is thereby decreased. The policy of allowing hiring of expatriate labor is beneficial in overcoming labor scarcity. However, in the long-run both farm productivity need to improve to be competitive with legislated income receivable from nonagricultural employment and ideally labor markets need to operate freely, to enhance food security and assure employment of Omani labor in agriculture.

Coastal China

The rapid development of urbanization and industrialization in coastal China in the past 20 years has exerted a huge squeezing effect on agricultural land use. The phenomenon of non-grain production on cultivated land (NGP) is very common, seriously threatening the protection of high-quality arable land and national food security. In order to find out the overall situation regarding NGP on cultivated land in coastal China, this study revealed the spatial differentiation of NGP and its main driving factors by spatial autocorrelation analysis, multiple linear regression models and geographically weighted regression analysis (GWR). The results show that: (1) in 2018, the non-grain cultivated land area of 11 provinces along the coast of China was about 15.82 × 106 hm2, accounting for 33.65% of the total cultivated land area. (2) The NGP rate in 11 provinces gradually decreased from south to north, but the NGP area showed two peak centers in Guangxi province and Shandong province, then decreased gradually outwards. (3) The low economic benefit of the planting industry (per capita GDP and urban-to-rural disposable income ratio) was the most important driving force, leading to the spatial differentiation of NGP, while the number of rural laborers and land transfer areas also acted as the main driving factors for the spatial differentiation of NGP. However, the influence of each driving factor has obvious spatial heterogeneity. The non-grained area and the non-grain production rate at the municipal level were completely different from those at the provincial level, and the spatial heterogeneity was more prominent. In the future, the local government should control the disorganized spread of NGP, scientifically set the bottom line of NGP, reduce the external pressure of NGP, regulate multi-party land transfer behavior, and strengthen land-use responsibilities. This study can provide a scientific foundation for adjusting land-use planning and cultivated land protection policies in China and other developing countries.

The aim of this study is to diagnose and identify trends for agricultural land use structure in the Central and Eastern European countries. Particular attention has been paid to the spatial differentiation characterising that structure, and to the significance that diverse kinds of conditioning have had in shaping it. Analysis has extended to the basic structural elements of agricultural land that are arable land, grasslands and permanent crops, while the countries included are the East-Central Europe acceding to the EU, i.e., Estonia, Latvia, Lithuania, Poland, Czechia, Slovakia, Hungary, Romania, Croatia, Slovenia and Bulgaria. The main sources of database have been Eurostat and FAO. The region under study emerges as very much diversified in terms of structure relating to structural elements of agricultural land. However, once the Eastern Bloc fell, all the countries experienced losses in area of agricultural land, as well as declines in the amounts of land growing permanent crops. Where key crops were concerned, the share of industrial species increase at the expense of vegetables, fruits and potatoes cultivation. Key factors underpinning observed trends for land use comprised privatisation and restitution of land, demographic processes in rural areas, domestic and EU agricultural policies as well as agro-ecological conditions.

Investigating spatiotemporal dynamics and varying relationships between water table depth (WTD) and land use changes is critical for efficient groundwater management and land use planning in arid zones. The primary objective of the present study is to combine satellite and field measured data to quantitatively analyze variations in WTD and its relationship with land use change in the Ogan–Kucha River Oasis in the northwest arid zones of China, and reveal the spatial heterogeneity and variations in the abovementioned relationship at spatiotemporal scales. The spatiotemporal variations in WTD and land use change at different time intervals (1997–2007, 2007–2017, and 1997–2017) were analyzed based on geostatistical analysis methods and grid cell approaches. The relationships between land use types and changes in WTD were assessed using correlation and ordinary least square analyses. The relationships between spatiotemporal variations in WTD and land use change were explored using local level geographically weighted regression. The results indicated that influences of human activity on the variation of WTD have gradually increased, and that WTD has declined rapidly in most parts of the study area. The spatial distribution of WTD exhibited significant spatiotemporal heterogeneity, and WTD was lower in the inner parts of the oasis and shallower in the oasis-desert ecotone. The WTD decline rates in the irrigation area were much higher than those in the oasis-desert ecotone. The cultivated land area has expanded markedly, whereas the shrub covered area has shrunk rapidly. Changes in WTD were positively correlated with changes in cultivated land area, and the expansion center of cultivated land has gradually moved from upstream of the alluvial fan to downstream of the alluvial fan and to the oasis-desert ecotone. The relationships between changes in cultivated land and WTD in the ecotone were more prominent than those in the inner parts of the oasis. Therefore, agricultural land expansion and planning in the study area should be integrated based on spatiotemporal changes in the groundwater depth to maintain the stability of groundwater systems and sustainable groundwater exploitation.
