“…The two most predictable components of climate change (trends and seasonality) are susceptible to distinct forms of adaptation; the former requiring a secular shift in agricultural technology with the latter also being addressable by technologies like water storage and financial services. Specific policies introduced in Brazil to address heightened seasonal variation include sustainable water management ( 28 ) and agroforestry ( 29 ). Increases in idiosyncratic shock variance can be dealt with a smaller spatial scales via storage, transport infrastructure, and diversification, while increases in covariate shocks will undermine these local solutions, requiring larger-scale institutional solutions and at the limit require reaching into global risk pools via sovereign borrowing and international reinsurance.…”

Effective policies for adaptation to climate change require understanding how impacts are related to exposures and vulnerability, the dimensions of the climate system that will change most and where human impacts will be most draconian, and the institutions best suited to respond. Here, we propose a simple method for more credibly pairing empirical statistical damage estimates derived from recent weather and outcome observations with projected future climate changes and proposed responses. We first analyze agricultural production and loan repayment data from Brazil to understand vulnerability to historical variation in the more predictable components of temperature and rainfall (trend and seasonality) as well as to shocks (both local and over larger spatial scales). This decomposed weather variation over the past two decades explains over 50% of the yield variation in major Brazilian crops and, critically, can be constructed in the same way for future climate projections. Combining our estimates with bias-corrected downscaled climate simulations for Brazil, we find increased variation in yields and revenues (including more bad years and worse outcomes) and higher agricultural loan default at midcentury. Results in this context point to two particularly acute dimensions of vulnerability: Intensified seasonality and local idiosyncratic shocks both contribute to worsening outcomes, along with a reduced capacity for spatially correlated (“covariate”) shocks to ameliorate these effects through prices. These findings suggest that resilience strategies should focus on institutions such as water storage, financial services, and reinsurance.

“…Such barriers to gaining more profits will impact how farmers perceive and adapt to innovations, especially in the developing world. Farmers attracted to innovation tend to analyze their peer's situations after implementing a system (Martinez, Maia and Garcia, 2022). Nevertheless, farmers who experience economic profits when adopting new practices will have a better perception.…”

Farmers struggle to combat uncertain climate issues while encountering pressure on conventional farming practices that lead to carbon emissions, water and soil pollution, and other environmental harms. A growing body of literature investigated circular economy and sustainable practices to support environmental-friendly agriculture activities while providing opportunities for farmers to improve their farm income. Therefore, a study synthesizing previous literature while identifying actual policy to boost farmers’ implementation of sustainable agriculture is worthwhile. Using the Systematic Literature Review analysis, this paper aims to identify farmers’ views on climate change adaptation and mitigation, challenges in implementing circular economy and sustainable practices, and policies to support farmers’ transition toward sustainable agriculture in developed and developing countries. We found that (1) farmers’ awareness of climate change, knowledge and skills are prominent for adapting and mitigating climate change in both types of countries, (2) farmland size, risks of income loss, and training and extension services influenced farmers’ adaptation and mitigation strategies for climate change in developing countries, (3) farmers in both types of countries experienced uncertainty in economic profits and legislative issues when adopting sustainable practices, while farmers in developing countries issued significant up-front expenses to acquire technology to adopt sustainable practices, (4) financial access and incentives through policy can be valuable to develop sustainable livelihoods, especially for farm households.

Various social and political entities are now promoting sustainable industrialisation through cultural transformations in regulation via research, education, ethics, politics and governance. The increasing uncertainties around dealing with the scope of environmental challenges also emphasise the need to consider these issues as social‐ecological systems. Prior reviews on sustainable strategies and circular economies have not approached the literature from this angle. To address this gap, we carried out a systematic literature review to generate insights into the evolution of sustainable strategies for circular economy ecosystems. This review combines bibliometric techniques with content analysis to identify the main thematic groups and research trends. We also put forward a framework for circular ecosystem‐related sustainable strategies that may not only assist scholars, policymakers, organisations and stakeholders in advancing with their respective projects but also provide an agenda for future research on this field.
