In this study, the impacts of small‐scale farmers on food security enhancement were estimated in three dimensions of food availability, food access and food utilization. In the current study, a systematic review and meta‐analysis have been performed to synthesize results from 75 original articles. It includes the pooling of data that quantitatively investigate whether or not causal links characterized in the original articles remain valid across a broader scope of the literature. The findings show that farmers who are small‐scale in natural/physical capital would lead to higher median food production and agricultural productivity, compared with small‐scale farmers in financial capital, at about 19% and 15%, respectively. Meta‐regression results indicate that small‐scale farmers in natural/physical capital have significantly positive effects on the average agricultural productivity, food income and biofortification. By contrast, farmers who are small‐scale in financial capital have negative effects on food security. The influential role of these small‐scale farmers should also be considered since food insecurity leads to socio‐economic implications. Therefore, it is recommended to cultivate higher value crops, to participate in various income‐generating activities such as fisheries and forestry, and to pay agricultural credits. The effect of the size of small‐scale farmers on global food security is very useful for policymakers to plan for a world without hunger. © 2022 Society of Chemical Industry.

“…For example, Meishan City has a relatively good ecological environment, but its level of urban development is relatively low, with low land-use efficiency. There are still many cities in China with similar low land-use efficiency [82,83]. In the urban development model, such cities should focus on improving urban land-use efficiency.…”

The global ecological decline resulting from urban development presents a significant challenge for numerous regions striving to reconcile conservation efforts with developmental needs. This study explores the relationship between ecosystem service value (ESV) and habitat quality (HQ) under various scenarios to elucidate prospective development trajectories. This study utilized the PLUS model to simulate land use patterns in the Chengdu metropolitan area across four distinct development scenarios. Furthermore, it employed the equivalent factor method and the Invest model to quantify ESV and HQ values, and investigated the coupling coordination between ESV and HQ for each city using a coupling coordination model (CCM). The findings are as follows: (1) Between 2000 and 2020, land use in the Chengdu metropolitan area primarily expanded through the development of construction land. (2) Concurrently, ESV demonstrated a fluctuating trend characterized by an initial decline succeeded by an upsurge, culminating under the Development–Ecological Balance Scenario. Likewise, HQ displayed a similar fluctuating pattern with an initial decline succeeded by an increase, reaching its zenith under the Ecological Dominance Scenario. (3) The coupling coordination between ESV and HQ exhibited variability across cities and scenarios. Ultimately, this study offers a distinctive perspective on evaluating the interplay between urban development and conservation, providing valuable insights for promoting sustainable development in other regions.

“…We use the ratio of stock industrial land area to built-up area to measure the costs of stock industrial land redevelopment. It has been documented that many local governments are currently forced to bear considerably high costs when redeveloping inefficiently used industrial land (Hu et al, 2019;Xiong et al, 2021). As we are limited by data availability, we cannot measure the total costs that local governments incur to redevelop all inefficiently used industrial land within their jurisdictions.…”
