“…However, place-based research has provided evidence that challenges the appropriateness of this binary view, where specific management strategies are being favoured due to drivers other than yield optimisation. For example, in rural developing conditions, strategies such as keeping fruit trees and crop diversification contribute significantly to maintaining household nutrition, sometimes at a cost to optimising yield or income (Fanzo et al 2013;Pellegrini and Tasciotti 2014). Similarly, agro-forestry can contribute to both food and sustainability goals through simultaneous production and carbon sequestration.…”

A gap between the potential and practical realisation of adaptation exists: adaptation strategies need to be both climate-informed and locally relevant to be viable. Place-based approaches study local and contemporary dynamics of the agricultural system, whereas climate impact modelling simulates climate-crop interactions across temporal and spatial scales. Cropclimate modelling and place-based research on adaptation were strategically reviewed and analysed to identify areas of commonality, differences, and potential learning opportunities to enhance the relevance of both disciplines through interdisciplinary approaches. Cropmodelling studies have projected a 7-15% mean yield change with adaptation compared to a non-adaptation baseline (Nature Climate Change 4:1-5, 2014). Of the 17 types of adaptation strategy identified in this study as place-based adaptations occurring within Central America, only five were represented in crop-climate modelling literature, and these were as follows: fertiliser, irrigation, change in planting date, change in cultivar and area cultivated. The breath and agency of real-life adaptation compared to its representation in modelling studies is a source of error in climate impact simulations. Conversely, adaptation research that omits assessment of future climate variability and impact does not enable to provide sustainable adaptation strategies to local communities so risk maladaptation. Integrated and participatory methods can identify and reduce these sources of uncertainty, for example, stakeholder's engagement can identify locally relevant adaptation pathways. We propose a research agenda that uses methodological approaches from both the modelling and place-based approaches to work towards climate-informed locally relevant adaptation.

“…Guvele (2001) analysed how multiple crop combinations affect the income variability in Sudan using the mean-variance model. Pellegrini and Tasciotti (2014) revealed the positive effect of crop diversification on income by regression analysis. However, most studies do not pass beyond the mean and variance.…”

“…As each crop has different trends of price and yield, farmers can reduce risk by cultivating more than one crop. Crop diversity can thus be considered as one of the strategies to mitigate the risk and the uncertainties that farmers face (Heady, 1952;Bhattacharyya, 2008;Rahman, 2009;Pellegrini and Tasciotti, 2014) through the portfolio effect. The portfolio theory (Markowitz, 1952) states that the investor can minimise the risk under uncertainty and stabilise the return by investing in more than one asset.…”

Temporal fluctuations of crop price and yield can have a strong influence on farmers' revenue. Under uncertainty, farmers' crop selection on -what to cultivate and how much of their land to allocate to different crops-is of crucial importance to secure their revenue as well as related ecosystem services. Multi-crop farming can be seen as a strategy to mitigate uncertainties that farmers face. In this study, we used Singular Spectrum Analysis (SSA) to quantify the fluctuations of crop price and yield for single and multiple crop selections in South Korea. Furthermore, risk adjusted revenue of each crop selection was analysed using the Sharpe ratio. We constructed three empirical crop portfolios containing one, three and five crops. For the single crop farming, six main crops in South Korea were analysed, and household data were used to build empirical crop portfolios. Our results showed that revenue from rice farming was the most stable, whereas it fluctuated strongly for pepper. However, growing rice provided the lowest revenue and farmers who cultivate multiple crops might as much as double their revenue compared to rice farming. Diversified crop farming can be a means of enhancing revenue. The biggest part of fluctuations in portfolios with several crops was seasonal, which might be mitigated by planning in advance. The artificial stability of rice price was due to policy intervention. However, it should be noted that the rice policy has been reformed and a high protection for domestic rice farming would no longer last in the future in South Korea. These results might have practical consequences for farmers' decision making on crop selection as well as for agricultural policy.

“…The higher production diversity in the Northeast may be related to the prevalence of subsistence crops, which are important to guarantee nutritional security for low income farm households. Pellegrini and Tasciotti (2014) analyze eight developing economies emphasizing the importance of crop diversification to food security of rural families. They did find a positive correlation between the number of crops, family income, and dietary diversity.…”

The level of production diversity chosen by small household farms may not be optimal from a social perspective, due to the existence of market failures such as environmental externalities or barriers to credit. Public policies designed to stimulate more diversified crops are supposed to correct that inefficiency. Understanding the socioeconomic characteristics associated with agricultural diversification is important for a successful implementation of those policies. In this paper we investigate which are those characteristics that are mostly related with crop diversification. Unlike previous studies, which use small samples, circumvented to small geographical areas, we address these issues with a large and comprehensive dataset, with observations spread through a large geographical dimension, making it possible to analyze the role played by regions. We take a group of 4.7 million Brazilian farm households, of which a random sample is extracted and used in the estimation procedures. We then estimate a Tobit regression model using key agricultural variables and the well-known Simpson Diversification Index to measure crop diversification. The main findings are that the region where the farm is located, the on and off farm incomes, the farm's size, the access to technical assistance, the farmer's age and education all play important roles in explaining production diversity. Public policies will more likely achieve crop diversification if they take into account those characteristics.
