“…Under these current conditions in the Peruvian Altiplano, the introduction of heattolerant and drought-resistant potato genotypes [67,68], as well as the cultivation of bitter potato varieties [69], the development of irrigated agriculture reversing the loss of traditional knowledge [47], the adoption of sustainable agricultural practices [17], the adoption of strategies for climate-resilient sustainable agriculture (CRSA) [18], and techniques to reduce crop water loss [70], are required as an essential strategy for adapting to climate change and variability, as these are issues of current global concern due to their impact on agricultural production [71].…”

Ensuring global food security and adapting to the challenges posed by climate change, particularly in rainfed agriculture, are paramount concerns. This research investigates the impacts of climate change on the yield of the potato crop variety Imilla Negra (Solanum tuberosum spp.) under the extreme climatic conditions of the Peruvian Altiplano. From the experimentation in six crop plots under a rainfed agricultural system, periodic crop growth parameter measurements were obtained from 2017 to 2018. The results showed a good performance of the AquaCrop model in the calibration and validation, successfully simulating crop growth and yield parameters. Climate projections showed precipitation decreases and temperature and evapotranspiration increases for the representative concentration pathway (RCP), RCP 4.5, and RCP 8.5 scenarios in 2023–2050. A comparison of crop yields between the base period (2006–2021) and the period 2023–2037 showed no significant changes, whereas a more considerable decrease was observed for the period 2038–2050. It is concluded that climate change generates moderate impacts on potato crop yields under the rainfed agricultural system in the Peruvian Altiplano due to the average reduction in precipitation.

“…In addition, the agricultural sector suffers more damage when farmers shift their labor from the on-farm to the off-farm sector due to climate change [7]. Farmers will be able to boost agricultural productivity [3][30] [31] and improve labor utilization by implementing adaptation strategies.…”

Climate change has hurt several sectors, but agriculture has been a tough hit. Small farmers are the people most affected by climate change because they have less access to resources and information. Their household welfare is lowered as a result, and they are unable to avoid the effects of climate change. To lessen the negative effects of climate change, farmers have to figure out how to adapt to it. This study uses a household economic model to examine the relationship between livelihood assets and strategic adaptation using the framework of systems thinking. This research has created causal loop diagrams (CLDs) based on a literature review to capture crucial variables in farmer households’ economic behavior under climate change conditions. By using these CLDs, more studies can be conducted to enhance the welfare of rice farmers through multiple policy simulations.

“…Research on natural risks mainly focuses on three aspects: first, to explore the methods of assessing agricultural risks [20,21]; second, it is to discuss the impact of climate change on agricultural production output at the macro level [22,23]; third, it is to analyze the impact of relative poverty brought about by natural risks from the perspective of rural households, impact on technology adoption [24], etc. It can be found that few studies have explored the relationship between natural risks and farmers' agricultural production trusteeship decisions [25]. In the survey, it was found that when natural risks occur, farmers will experience disputes with trustees because of production.…”

As the main service mode and management mode of socialized service, agricultural production trusteeship services (APTS) are an important way to realize the tight link between farmers and modern agricultural development, which is highly important for ensuring national food security. By constructing a utility model of farmers, this paper deduces the decision-making mechanism of farmers’ APTS from the dual mechanism of natural risk and non-agricultural employment income (NAEI) and uses the survey data of 956 farmers in the three northeastern provinces to verify the empirical results by using multivariate logit (Mlogit) and propensity score matching (PSM) methods. The research shows that natural risk hinders farmers’ choice of the APTS; NAEI has a positive impact on APST, and an increase in NAEI weakens the negative effect of natural risk on the choice of the APTS, and has an enhanced moderating effect. In addition, the scale heterogeneity analysis revealed that the impacts of natural risk and NAEI on farmers of different scales are significantly different. The NAEI adjustment effect has the greatest impact on small-scale farmers, followed by medium-scale farmers. In view of this, the government should stabilize the nonagricultural employment market and improve the nonagricultural employment opportunities of farmers. APTS organizations should transfer natural risks and improve the agricultural insurance system. According to the differences of different scales of farmers, different promotion policies are formulated, and the expansion of management and deepening services is proposed to further promote the development of APTS and consolidate the foundation of food security in China.
