“…X is the production input, and λ is the weight vector Nx1 (weight value obtained from programming results, defines the linear combination of the peers of the i DMU). In the research of Molua et al [9] and Dogba et al [10], the output variable used in the DEA is cassava production (in tonnes), denoted as y. In the research of Molua et al [9], the inputs used in the production are land (farm size), labor efforts, cassava stem/cuttings, and farm tools (machete and hoes).…”

Wonogiri Regency was the area with the highest cassava production in Central Java in 2021, but the level of productivity is lower than the national productivity. The level of productivity is related to the inefficiency of inputs. The purpose of this study is to analyze the efficiency of cassava farming through the relationship between the inputs and outputs of cassava and socioeconomic factor which affects the efficiency. The basic method of the research is descriptive and quantitative, with primary data from 105 cassava farmers. Input-output analysis of the efficiency level use approach of Data Envelopment Analysis (DEA) and analysis of socioeconomic factors affecting the efficiency level with Tobit’s regression. The input-output analysis with DEA results showed that 32% of cassava farmers in Wonogiri were already technically efficient, with an average value of 0.855. Increasing productivity through efficiency can be done by reducing the use of slack inputs, especially in the seed, organic fertilizer, and urea fertilizer. The Tobit regression results showed that farmers’ experience, education, and participation in the farmers’ group positively affected cassava’s efficiency in the Wonogiri Regency. The study’s implication is to increase farmer groups’ role in providing information on the efficient use of inputs needed to increase cassava productivity.

“…Cassava production, both in terms of area under cultivation and yields has increased over the last 50 years and is mostly cultivated in the tropics (Delaquis et al, 2018; Molua et al, 2020). It is cultivated on approximately 27 million ha throughout tropical and subtropical regions in Africa and Asia, of which 1.4 million ha (5%) is from Thailand (FAOSTAT, 2021).…”

Land degradation, declining soil fertility, and erosion continue to plague agricultural production in many developing countries. In response to these farm production constraints and environmental challenges, a range of soil conservation technologies and practices have been developed and disseminated to tackle soil nutrient and fertility declines. However, evidence on the association between soil conservation, farm performance, and smallholder welfare is scarce. In this study, we examine the relationship between soil conservation, farm performance, and welfare outcomes of smallholder cassava farmers in Thailand. We use a farm household survey of 602 cassava growers and apply a doubly robust multivalued treatment effect estimator to estimate the relationship between soil conservation, farm performance, and welfare as well as the observable characteristics associated with the use of soil conservation practices. We observe a positive association between the use of soil conservation practices and cassava yields which is most likely associated with higher‐income streams. Similar insights are also observed for other welfare outcomes such as asset accumulation, including livestock which represents rural wealth to a considerable extent. The positive association between soil conservation and livestock ownership hints at some form of rural diversification. Given these insights, our analysis supports and gives credence to initiatives that promote the adoption of soil conservation as they are not only pro‐poor but also environmentally friendly with significant concerns for ecological safeguards.

“…With increasing refugees such as in the Central African Republic, environmental stress such as in Chad, inefficient policy preferences as reported for Gabon and Equatorial Guinea, the burgeoning populations in neighbouring Nigeria and The Republic of Congo, as well as the disruptions in food supplies caused by Russo‐Ukrainian war; food insecurity is reinforced. Cameroon produces a variety of annual, biennial, and perennial crops such as maize, cassava, legumes, vegetables, and fruits (Molua et al, 2020; Tabe‐Ojong et al, 2021). It is also part of the Congo Basin Forest that provides key ecosystem services, but the forest is increasingly cleared for oil palm production which constitutes an important livelihood activity for some smallholders (Tabe‐Ojong et al, 2022).…”

Food insecurity remains a persistent policy issue in many developing countries. While socio-political, epidemiological, climatic, and productivity-related factors have received attention regarding food insecurity, a rarely considered factor is the changing quality of the soil, a natural resource base that has the potential of increasing or reducing vulnerability to food insecurity. The use of organic soil amendments may be socioeconomically and environmentally advantageous. This study examines the inherent relationship between the use of organic soil amendments and food security among smallholder farming households. Using the seemingly unrelated bivariate probit model and the recursive bivariate probit (RBP) model on nationally representative household-level data from Cameroon, we find evidence that the use of organic soil amendments is positively associated with household food security. We also find the use of organic soil amendments to be associated with reduced levels of mild, moderate, and severe food insecurity. Empirical evidence is also suggestive of a positive association between crop diversification and food security. The results further show that households with larger farm sizes tend to use more organic soil amendments than households with smaller farms. Taken together, our findings confirm another pathway of improving food security with implications for the broad path toward achieving the UN Sustainable Development Goals (SDGs), particularly SDG 2 of ending hunger.
