Special Issue Information

Dear Colleagues,

Food insecurity is now a major problem in many countries all over the world. This situation has affected many people in many contexts, including developing countries, such as many African states, and many developed countries. Food insecurity sometimes affects the territories and rural areas located far from large cities but there are also food insecure populations integrated in urban contexts within cities. Food insecurity is inevitably linked to accessibility (costs and ease of access to healthy food) and to neighborhoods in cities and rural areas where populations are poor. Climate change can have major effects on the urban and rural environment as well as food production and can potentially reduce food production to the point where local people may not have access to enough food at reasonable costs. This situation can adopt other worrying dimensions and worsen even more.

This Special Issue addresses multiple questions: how climate change has majorly and negatively impacted food insecurity either in urban neighborhoods or in rural agricultural territories. Additionally, what are the ways to address this food insecurity created by climate change, e.g. by modifying food production methods (both crops and foodstuffs of animal origin), and how social organizations can create the conditions for ensuring healthy food is available to poor populations in cities or rural areas by involving relatively well-to-do people helping to lower the prices of food available to poor people. New initiatives are expected to emerge through the involvement of citizens' groups and groups of farmers who wish to contribute to reducing the food insecurity created by climate change and other factors such as the rise in the prices of food for poor consumers. Furthermore, this Issue will reflect on whether the implementation of new policies in the agricultural sector and the use of new techniques based on artificial intelligence can remedy this situation.

Research articles, review articles, and short communications are invited.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Climate is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Climate-smart agricultural technologies offer transformative potential for achieving Sustainable Development Goals, especially in mitigating extreme weather impacts and enhancing food security. Despite this potential, adoption rates remain limited due to various factors, with perceived complexity playing a significant role. This study conducted a systematic review and meta-analysis to assess the influence of perceived innovation complexity on adopting climate-smart technologies. Using frameworks of the Technology Acceptance Model and the Unified Theory of Acceptance and Use of Technology, we systematically reviewed 28 studies and conducted a meta-analysis of 15 studies across diverse geographic contexts. Our findings from the systematic review indicate inconsistent results on the impact of complexity on adoption due to the different items and scales used to measure the concepts of complexity across contexts, suggesting that there is a need for the development of a standardized scale to measure complexity. Results from the meta-analysis generated a summary effect size (r = 0.51, 95% CI = [0.05, 0.72], z = 6.78, p ≤ 0.0001), revealing a significant relationship between perceived complexity and adoption intent. The effect size of 0.51 indicates that higher complexity levels significantly decrease the likelihood of adoption intent for climate-smart technologies. Differences in CSA research trends across geographic regions highlight the need for tailored approaches to technology adoption that take into account the specific capabilities and constraints of each region. These findings provide valuable insights for policymakers, Extension professionals, and technology developers to design interventions to promote ease of use and enhance technology diffusion in sustainable farming practices and food security. These findings contribute to ongoing efforts to foster sustainable agricultural innovations, offering guidance to accelerate the global transition to more resilient farming systems. Full article
