Farmers’ Subsistence in Indonesian Rice Farming

Along with the importance of the rice industry in the agricultural sector and rural development in Indonesia, it arguably requires the understanding of whether rice farmers have been experiencing changes in their agricultural practices. Within the existing literature, it is commonly found that most farmers in developing countries are characterized as subsistence farmers. This paper aims to explore what factors affecting the degree of farmers’ subsistence in the Indonesian rice industry. To this end, this study employed regression analysis using data from the national agricultural survey in 2014. The empirical results find that both the characteristics of farm households and rice on-farm characteristics have statistically significant effects on the farmers’ decision whether to commercialize or become subsistence. In addition, the farm gate price is also found to have a statistically significant effect, but the effect is found to be relatively small. In general, this study suggests that subsistence farming in the Indonesian rice industry is still significant though many literatures have emphasized the existence of structural change in the agricultural system in Indonesia.

Quantifying the nutritional and income loss due to crop raiding in rural African subsistence farming community in South Africa

Globally, crop damage by wildlife contributes to food insecurity through direct loss of food and income. We investigated the calories lost and potential economic impact of crop raiding to subsistence homesteads abutting the Hluhluwe Game Reserve and assessed their mitigation measures to combat crop raiding. We quantified the seasonal loss of calories (KJ/g) of four common crops: beetroot (Beta vulgaris), common bean (Phaseolus vulgaris), maize (Zea mays) and spinach (Spinacia oleracea) and determined seasonal potential income loss based on local market cost of crops. Experimental data used for this study were collected from April 2016-March 2017 and questionnaire data were collected in March 2016, using a stratified sampling approach to sample the homesteads. We selected every second homestead for the interview and restricted the survey to one respondent per homestead to avoid pseudo-replication of results. In the one year of sampling, we did not record any large mammals crop raiding, both from direct observations and camera trap footage, we also did not find a statistically significant relationship between the level of damage and distance of farms from the reserve boundary. Throughout the study, we captured a total of 96 individual rodents comprising of two species: red bush rat (Aethomys spp.; 67.7%; 51 males and 28 females) and pouched mouse (Saccostomus campestris; 32.3% (14 females and three males ) and we used the damage caused by these animals and other small animals to quantify the level of damage. We found that season, crop type, farm slope and the interaction between season and crop type were significant predictors of relative calorie loss. Again, season, crop type and the interaction between season and crop type were significant predictors of the potential income loss, with the highest income loss recorded for spinach in the dry season. In addition, significant differences were found for potential income loss for all crop types in the wet season, and for the interaction between crop types maize, spinach and the wet season, but no significant difference was found for crop type common bean and the wet season. A multinomial regression analysis revealed that crop raiding animal type, crop types raided and distance of farms from the reserve all had a significant effect on the choice of mitigation measures farmers used. Most importantly we found the highest relative calorie loss for maize during the dry season, which could impact on subsistence farmers by reducing their daily calorie intake and impact on their food security especially during the season where subsistence farming is slow. Moreover, as the most preferred mitigation measure by farmers can have opportunity costs to this community, such as the loss of school time for children. These results have important implications for food security policies and socially related policies and practices.

Structural Change and Internal Labor Migration: Evidence from the Great Depression

We analyze sectoral labor reallocation and the reversal of urbanization in the U.S. during the Great Depression. The widespread movement to farms, which serves as a form of migratory insurance during the crisis, is largely towards farms with low levels of mechanization. In contrast, the mechanized agricultural sector sheds workers, many of whom reallocate into low-productivity or subsistence farming. The crisis perverts the normal process of structural change—in which workers displaced by farm equipment are released into more productive occupations—suggesting that macroeconomic fluctuations are an important factor determining the labor market consequences of technological change.

Potential Use of Native Yeasts to Produce Bioethanol and Other Byproducts from Black Sugarcane, an Alternative to Increment the Subsistence Farming in Northern Ecuador

The high consumption of energy, mainly in the automotive sector, is supplied by fossil fuels, which, when combusted, generate polluting gases leading to the great problem of climate change. This has led society to seek alternatives. Bioethanol is a biofuel that can be obtained from the fermentation of different raw materials rich in sucrose such as sugarcane, which can be mixed with gasoline and used to reduce polluting emissions. The following investigation focused on studying the efficiency of three selected native yeasts in the fermentation of black sugarcane POJ 27-14 variety juice to produce bioethanol and other byproducts of biotechnological interest. A comparison between the size of the inoculum of three selected native yeasts (Lev6, Lev9, and Lev30) and two reference commercial controls in the fermentation process was performed. The phylogenetic classification was carried out based on the analysis of the internal transcribed spacer 1 sequence, 5.8S ribosomal RNA, and internal transcribed spacer 2. Lev6 and Lev30 were classified as Saccharomyces cerevisiae, while Lev9 was Candida intermedia, with 99% nucleotide sequence identity. The results showed that the optimal growth temperature was 30 °C with constant agitation (200 rpm) for biomass production. The Lev30 strain presented the highest yield in the production of biomass from sugarcane juice fermentation, while the Lev6 strain presented the highest yield in ethanol production. Additionally, among native yeasts, Lev6 registered the highest ethanol concentration (Q) and volumetric productivity (Qp) values of 0.61 (g/L/h) and 43.92 g/L, respectively, which were comparable with the control yeasts. The gas chromatography coupled to mass spectrometry (GC-MS) indicated the presence of ethanol in all samples (98% to 99% relative percentages) along with some therapeutic substances such as (2-aziridinylethyl) amine and tetraacetyl-d-xylonic nitrile with greater efficiency than commercial controls from the alcoholic fermentation of black sugarcane juice.

Understanding antimicrobial use in subsistence farmers in Chikwawa District Malawi, implications for public awareness campaigns

Drug resistant infections are increasing across the world and urgent action is required to preserve current classes of antibiotics. Antibiotic use practices in low-and-middle-income countries have gained international attention, especially as antibiotics are often accessed beyond the formal health system. Public awareness campaigns have gained popularity, often conceptualising antimicrobial resistance (AMR) as a problem of excess, precipitated by irrational behaviour. Insufficient attention has been paid to people’s lived experiences of accessing medicines in low-income contexts. In Chikwawa District, Malawi, a place of extreme scarcity, our study aimed to understand the care and medicine use practices of households dependent on subsistence farming. Adopting an anthropological approach, we undertook medicine interviews (100), ethnographic fieldwork (six-month period) and key informant interviews (33) with a range of participants in two villages in rural Chikwawa. The most frequently used drugs were cotrimoxazole and amoxicillin, not considered to be of critical importance to human health. Participants recognised that keeping, sharing, and buying medicines informally was not the “right thing.” However, they described using antibiotics and other medicines in these ways due to conditions of extreme precarity, the costs and limitations of seeking formal care in the public sector, and the inevitability of future illness. Our findings emphasise the need in contexts of extreme scarcity to equip policy actors with interventions to address AMR through strengthening health systems, rather than public awareness campaigns that foreground overuse and the dangers of using antibiotics beyond the formal sector.

Extent, Distribution, and Causes of Soil Acidity under Subsistence Farming System and Lime Recommendation: The Case in Wolaita, Southern Ethiopia

Soil acidity is one of the most important environmental threats to the Ethiopian highlands where the livelihood of the majority of people is reliant on agriculture. Yet, information regarding its extent, distribution, causes, and lime requirement at a scale relevant to subsistence farming systems is still lacking. This study (1) investigates the extent and spatial distribution of soil acidity, (2) identifies factors attributing to soil acidification, and (3) predicts the lime requirement for major crops. A total of 789 soil samples were collected from arable lands in the Wolaita area which is mainly characterized by poor soil fertility and soil degradation in southern Ethiopia. Results revealed that the landscape is characterized by a gentle slope followed by strongly sloppy > flat > hilly topographies. Clay is the dominant soil textural class. A soil pH map, which is generated using geospatial analysis, demonstrates that 3.3, 78.0, and 18.7% of the total area were under strongly acidic, moderately acidic, and neutral soil reactions, respectively. The exchangeable acidity (Cmol(+)/kg) varied from nil to 5.1, whereas exchangeable Al ranged from 1.4 to 19.9 Cmol(+)/kg. The soil pH has shown a significantly ( p < 0.001) negative association with clay content (r = −0.33), exchangeable Al (r = −61), exchangeable acidity (r = −0.58), and inorganic fertilizer application (r = −0.33). Increased rates of diammonium phosphate (DAP) (r2 = 0.91) and urea (r2 = 0.88) markedly elevated soil acidity. Conversely, manuring showed a significant ( p < 0.001) and positive relationship with pH (r = 0.37) in which the increasing rate of manure significantly reduced acidification (r2 = 0.98). DAP and urea applications above 75 kg/ha lowered soil pH units by 0.56 and 0.48, respectively, <25 kg/ha while at the same time farmyard manure (FYM) at 4 t/ha raised pH by 0.75 units over the unfertilized field. Residue management significantly ( p < 0.001) influenced soil pH wherein it ranged from 6.09 (complete residue removal) to 6.61 (residue incorporation). Changes in land use, cropping intensity, and socioeconomic status were also significantly attributed to soil acidification. To curb the effects of soil acidity, the lime requirement for common bean growing fields varied from zero to 6.6 t/ha, while for maize it was between zero and 4.3 t/ha. It is concluded that soil management interventions such as maintaining and incorporating crop residues, integrated use of organic and inorganic fertilizers, liming, and enhancing farmers’ awareness should be advocated to overcome soil acidification and improve soil fertility. In addition, introducing crops with traits that tolerate acidity and Al toxicity is also suggested.

Farm Production Diversification and Dietary Diversity among Subsistence Farming Households: Panel Data Evidence from South Africa

Improving the production of a variety of foods by subsistence farmers has been identified as a key strategy for improving dietary diversity. However, there is limited evidence in South Africa on how one’s own production is linked to dietary diversity. This study relies on nationally representative panel data to investigate the extent to which farm production diversity is correlated with dietary diversity. The data indicated a moderate level of household dietary diversity that has been on a declining trend between 2008 and 2017. The farm households produced three food groups (meat, cereals, and vegetables), suggesting more reliance on food purchases than own production. The study found a positive relationship between own production diversification and dietary diversity and that dietary diversity varied by demographics and socio-economic characteristics of households. However, production diversity was not significantly associated with the consumption of micronutrient-rich foods such as fruits or vegetables. Higher levels of education, income per capita, food expenditure, and geographic location were some of the key drivers of dietary diversity among subsistence households. The findings suggest that encouraging subsistence farming households to produce various crop and animal species can be an effective strategy to improve dietary diversity among poor households in South Africa.

Explaining the Effect of Crop-Raiding on Food Security of Subsistence Farmers of KwaZulu Natal, South Africa

Across the globe, crop-raiding has been known to have a significant impact on subsistence farmers livelihoods in developing countries. However, the relationship between crop-raiding and food security of small-scale farmers is not well-studied. We investigated the effects of crop-raiding on homestead food security of a subsistence farming community on the edge of the Hluhluwe Game Reserve in northern KwaZulu-Natal Province, South Africa. We analyzed the relative calories lost to important food security crops (maize, common bean, spinach, and beetroot) damage by crop raiders. In addition, we conducted questionnaire surveys of resident farmers and conservationists of the Hluhluwe Game Reserve to explain the effect of crop-raiding on food security. We firstly assessed how crop loss influenced relative calorie loss as an indicator of food security by comparing relative calorie loss with two predictors of food security: homestead size and contribution of crops to the farmers' food basket. Larger homesteads were more prone to food insecurity as compared to smaller households as they experienced higher calorie loss, especially in terms of maize (Zea mays), the most important food security crop in South Africa. This was because maize contributed the highest (91–100%) to the homestead food basket of these farmers. Secondly, we assessed farmers and conservationists' perceptions and opinions on crop-raiding issues. Farmers reported maize as the crop most damaged by crop-raiding animals. Conservationists reported crop-raiding with other major problems in and around the Reserve; this showed that conservationists acknowledge the issue of crop-raiding as a problem for subsistence farming communities abutting protected areas. Both farmers and conservationists reported insects as the most damaging crop raider. Our study suggests that larger homesteads, particularly where maize contributes substantially to homestead food baskets, are more prone to food insecurity in the rural subsistence farming community that we studied. In concordance with many studies, insects were reported as the culprits by both farmers and conservationists. Small, ubiquitous animals, such as insects are reported to cause much crop damage where they occur. The findings of our study suggest that the food security of the studied farmers is threatened by crop-raiding.
