In Uganda, the agricultural sector contributes substantially to gross domestic product. Although the involvement of Ugandan women in this sector is extensive, female farmers face significant obstacles, caused by gendering that impedes their ability to expand their family business and to generate incomes. Gender refers to social or cultural categories by which women–men relationships are conceived. In this study, we aim to investigate how gendering influences the development of business relationships in the Ugandan agricultural sector. To do so, we employed a qualitative–inductive methodology to collect unique data on the rice and cassava sectors. Our findings reveal at first that, in the agricultural sector in Uganda, inter-organization business relationships (i.e., between non-family actors) are mostly developed by and between men, whereas intra-organization business relationships with family members are mostly developed by women. We learn that gendering impedes women from developing inter-organization business relationships. Impediments for female farmers include their restricted mobility, the lack of trust by men, their limited freedom in communication, household duties, and responsibilities for farming activities up until sales. Our findings also reveal that these impediments to developing inter-organization business relationships prevent female farmers from being empowered and from attainting economic benefits for the family business. In this context, the results of our study show that grouping in small-scale cooperatives offers female farmers an opportunity to overcome gender inequality and to become economically emancipated. Thanks to these cooperatives, women can develop inter-organization relationships with men and other women and gain easier access to financial resources. Small-scale cooperatives can alter gendering in the long run, in favor of more gender equality and less marginalization of women. Our study responds to calls for more research on the informal economy in developing countries and brings further understanding to the effect of gendering in the Ugandan agricultural sector. We propose a theoretical framework with eight propositions bridging gendering, business relationship development, and empowerment and economic benefits. Our framework serves as a springboard for policy implications aimed at fostering gender equality in informal sectors in developing countries.

Potatoes are an important cash crop for small-scale producers worldwide. The move away from subsistence to commercialized farming, combined with the rapid growth in demand for processed agricultural products in developing countries, implies that small-scale farmers and researchers alike must begin to respond to these market changes and consider post-harvest treatment as a critical aspect of the potato farming system. This paper presents and assesses a low cost potato-grading machine that was designed explicitly to enable small-scale potato growers to sort tubers by size for supply to commercial processors. The results of ten experiments reveal that the machine achieves an accuracy of sort similar to commercially available graders. The machine, which uses parallel conical rollers, has the capacity to grade different tuber shapes and to adjust sorting classes, making it suitable for locations with high potato diversity. Its relatively low cost suggests that an improved and adapted version of this machine might enhance market integration of small-scale potato producers not only in Peru, but in other developing countries as well.

Rice is the most economically important food crop in many developing countries and has also become a major crop in many developed countries where its consumption has increased considerably. It has become necessary to meet the demand of the world’s current population growth rate, and the least costly means for achieving this aim is to increase rice productivity, wherever possible. The main challenges encountered by rice processors in Nigeria are to find appropriate solutions for quality rice processing. Therefore this work provides basic information about the challenges of rice processing and focuses on the challenges faced by the small scale rice processors and reasons for continuous rice importation with a view to guiding decision-making to be self-sufficient in rice production, thereby making some improvement in Nigerian economy.

This article examines the social and environmental costs of living in the mineral age, wherein contemporary global livelihoods depend almost completely on the extraction of mineral resources. Owing to the logic of extractivism—the rapid and widespread removal of resources for exchange in global capitalist markets—both developed and developing countries are inextricably entangled in pursuing resource extraction as a means of sustaining current lifestyles as well as a key mechanism for promoting socioeconomic development. The past 15 years has seen a massive expansion of mineral resource extraction as many developing countries liberalized their mining sectors, allowing foreign capital and mining companies onto the lands of peasant farmers and indigenous people. This mining expansion has also facilitated the rise of artisanal and small-scale mining (ASM). Transformations in livelihoods and corporate practices as well as the environmental impacts and social conflicts wrought by mining are the central foci of this article.

A small-scale maize harvester was designed and fabricated for developing countries and is composed of a harvester header, a chain conveyor, a drive power unit and a five-wheel tricycle. Fabrication of components was made and assembling of the devices on the tricycle was done. The performance evaluation of the small-scale maize harvester was done at 15% kernels moisture content (wet basis). Three rotational speeds of the engine, 1347, 1521 and 1937 rpm were used, while the forward velocity of the harvester was kept at an average of 0.617 km.hr-1. The testing experiment revealed significant effect of physical properties of maize (p<0,05). The highest machine capacity was obtained at 0.05 ha.hr-1, while the highest driving efficiency was 97.30% and the highest picking and conveying efficiencies were 84.11% and 98.21%, respectively. However, it was observed that the machine noise level decreased with increase in engine speed. Also, the engine speed affected both picking and conveying efficiencies. The designed machine is found suitable for most smallholder farms.
