Key Findings

  • The study examined food security in China using data from 29 provinces between 2016 and 2020
  • China's agricultural economy is not sustainable, with efficiency levels decreasing across eastern, western, and central regions
  • Strengthening agricultural infrastructure, increasing policy support for green agriculture, and diversifying agricultural production are crucial to improving food security and nutrition
Ensuring food security is crucial for global food supply, economic development, and social stability. A recent study by Fujian Police College[1] examined food security in China using data from 29 provinces between 2016 and 2020. The study aimed to measure the efficiency of hunger eradication, food security, and nutritional improvement under varying rainfall conditions. It used innovative methods such as the Meta Entropy Two-Stage Dynamic Direction Distance Function (DDF) within an exogenous Data Envelopment Analysis (DEA) model. The study found that China's agricultural economy lacks sustainability, with efficiency levels decreasing across the eastern, western, and central regions. This suggests that different regions require tailored approaches to improve food security. The research highlighted the need to strengthen agricultural infrastructure, increase policy support for green agriculture, and diversify agricultural production to enhance food security and nutrition. Earlier studies provide context for these findings. For instance, research in Pakistan has shown that climate change negatively impacts irrigation, crops, livestock, rural livelihoods, and food security[2]. This underscores the importance of sustainable agricultural practices and policies to mitigate adverse climate effects. Similarly, a study on China's agricultural subsidy policy demonstrated that subsidies can significantly increase sown areas, grain production, and farmers' incomes, thereby improving food security[3]. However, the effectiveness of these subsidies varies by region due to differences in natural conditions and economic development. The current study builds on these insights by focusing on the efficiency of food security measures under the influence of rainfall, an exogenous variable. It identified key indicators such as the number of foodborne disease patients, iodine deficiency disease patients, stunting rate, malnutrition rate, obesity rate among children under five, and newborn visit rate to assess nutritional improvements. The findings suggest that while agricultural infrastructure and policy support are crucial, regional disparities must be addressed to enhance overall food security. To improve food security, the study recommends several measures. Strengthening agricultural infrastructure can help mitigate the impacts of adverse weather conditions and improve crop yields. Increasing policy support for green agricultural production can promote sustainable farming practices, reducing the environmental impact and ensuring long-term agricultural productivity. Diversifying agricultural production can help meet the nutritional needs of the population by providing a variety of food products. The study's innovative approach provides a comprehensive framework for assessing food security and nutritional improvements. By incorporating exogenous variables like rainfall, it offers a more nuanced understanding of the challenges and opportunities in different regions. This aligns with earlier findings that emphasize the need for region-specific strategies to address food security and agricultural sustainability. In summary, the study by Fujian Police College highlights the importance of tailored approaches to improve food security in China. By focusing on regional disparities and incorporating exogenous factors like rainfall, it offers valuable insights for policymakers and stakeholders. Strengthening agricultural infrastructure, increasing policy support for green agriculture, and diversifying production are key steps to enhance food security and nutritional outcomes. These findings build on earlier research[2][3], providing a more comprehensive understanding of the complex factors influencing food security and agricultural sustainability.
