Worldwide, the continuous advancement of off-grid solar photovoltaic irrigation seeks to improve water access, increase food production, and reduce carbon emissions and energy costs associated with fuel usage. Consequently, this enhances human resilience to climate change and contributes to the improvement of farmers’ income. This study investigates the influence of solar energy adoption on farmers’ income, drawing insights from 1,080 growers in Pakistan. It uses the logit model and propensity score matching (PSM) to address bias. Factors influencing income, including gender, education, decision-making autonomy, farm size, extension services, cooperative associations, access to credit, risk perception, market distance, and tube well availability, are identified. Findings reveal a positive correlation between solar energy adoption and increased crop farmer income. PSM analysis validates this, emphasizing the need for government and agricultural extension interventions to enhance financial accessibility for farmers facing mobility challenges. This includes subsidies for technology adoption and knowledge dissemination about digital technology. The study advocates for an accelerated adoption of solar energy to foster agricultural development in Pakistan. In resource-poor nations like Pakistan, government subsidies are crucial to offset technology costs for citizens facing challenges in affording green energy. Addressing Pakistan’s energy crisis through promoting solar energy for irrigation can amplify farmers’ income. It is imperative to promote access to this technology, particularly for water pumping, through subsidies and readily available credit facilities, given the resource limitations and small landholdings of many farmers in Pakistan.

Urban agriculture is recognized as a worthy resource to support a growing population as well as to provide other positive effects on urban ecosystems and their citizens. In this context, community gardens are considered key topics in terms of food production and food security, in both developing and developed countries, as well as in terms of social inclusion and participation. The general aim of this study was to assess the main spatial criteria recognized and shared by stakeholders to identify suitable and inclusive areas for community gardens by testing and developing a participatory process. Because of its size, population, and urban fabric, Padua (northeast Italy) was selected as a representative and emblematic case study for mid-sized cities in Europe. The methodology was based on field surveys of key informants and spatial multicriteria decision-making analysis in the open-source geographic information system environment of QGIS. The results identified neighborhoods to be prioritized in the design of new community gardens according to three scenarios: the distance index, the social index, and the combination of the two (overall index). To conclude, this study highlighted the importance of adopting a decision-making methodology to support local policymakers and municipal agencies that are interested in implementing other community gardens in Padua. The case study and the methodology adopted could also serve as important guides for cities by providing step-by-step processes that can be directly applied.

With increasing cost and use of energy in agriculture, the traditional practice of mono-cropping of rice in upland is neither sustainable nor eco-friendly. It is necessary to identify crop diversification options with high energy efficiency, productivity, and low global warming potential (GWP). In this experiment, an inclusive system analysis was accomplished for 3 years (2016–2019) of five mono-cropping production (MCP) systems namely rice (R), finger millet (FM), black gram (BG), horse gram (HG), pigeon pea (PP), and four intercropped systems viz. R+BG, R+HG, FM+ BG, and FM + HG. The key objective was to evaluate the flow of energy, carbon balance, and GWP of these varied production systems. Puddled rice was recorded as an energy-exhaustive crop (27,803 MJ ha−1), while horse gram was noted to have the lowest energy use (26,537 MJ ha−1). The total energy output from pigeon pea (130,312 MJ ha−1) and diversified intercropped systems (142,135 MJ ha−1) was 65.3% and 80.3% higher than mono-cultured systems, respectively. Rice and rice-based intercropping production systems showed higher carbon footprints (1,264–1,392 kg CO2 eq. ha−1). Results showed that R+BG and R+HG were the most energy-efficient production systems, having higher energy ratio (5.8 and 6.0), higher carbon efficiency (7.41 and 8.24), and carbon sustainability index (6.41 and 7.24) as against 3.30, 3.61, and 2.61 observed under sole cropping production systems. On average, rice and rice-based production systems had 7.4 times higher GWP than other production systems. In productivity terms, pigeon pea and FM+HG had higher rice equivalent yields of 8.81 and 5.79 t ha−1 and benefit-cost ratios of 2.29 and 1.87, respectively. Thus, the present study suggests that pigeon pea and finger millet-based intercropping systems were the most appropriate crop diversification options for the rainfed upland agro-ecosystem of the eastern region of India.

Seed systems are essential to bring good genetic material to farmers. Women farmers, however, have benefited less than men farmers from seed systems in low and middle income countries. We identify factors that inhibit and promote women's success in seed businesses through three case studies of women's and men's entrepreneurship across seed-related value chains and country contexts: tilapia seed production in Ghana, marketing and trading of improved maize and sorghum seeds in Kenya, and chicken seed dissemination in Tanzania. Applying a gender lens, we use key informant interviews and focus group discussions to analyze women's and men's motivations to engage in seed businesses, the challenges they confront to start and build their enterprises, and prospects for sustainability and continued success. We use quantitative data to characterize the levels of empowerment of the agripreneurs sampled. For women, the results show that the social normative context of the sector is critical. Time flexibility and profitability are important considerations for women's engagement. Furthermore, across all three country cases, family and external support are frequently key to women's participation and success in seed agripreneurship. The article discusses the importance of government bodies, NGOs, and donors in challenging the normative context around gender resource gaps, as well as provide technical packages and training to develop business acumen. Supporting change of restrictive gender norms in non-threatening ways - such as ICTs - is key.

Soybeans are an important oil and protein supply crop, but the utilization of by-products from its processing products has never been effectively resolved, while a large number of nutritional resources have been wasted and environmental pollution is serious, restricting the sustainable development of the industry. The critical problem of soybean processing by-products includes excessive levels of microorganisms, residual proteins, metal ions, and other substances. Because the screw extrusion process has potentially advantageous processing characteristics, it appears that it’s just the right solution to the above problem of soybean processing by-products. We propose that this technology may be a potentially scalable technology for the immediate processing of soybean by-products. This paper reviews the theoretical foundations in existing research, briefly discusses the technological advantages, feasibility, and potential risks of this process, and hopes that researchers may pay attention to this technique and conduct feasibility studies.

Plant-based meats (PBM) are an emerging set of food technologies that could reduce the environmental impacts of food systems by mitigating consumer demand for animal products. However, scaling up the production and consumption of plant-based meats requires overcoming multiple technological, regulatory, political, and market barriers. An evidence-based prioritization of needs and actions may help actors (e.g., investors, funders, policymakers) who wish to help scale PBM achieve desired outcomes with limited resources.What actions could most effectively help to scale up the production and/or consumption of plant-based meat in Brazil?We selected Brazil as a case study of a country with a significant animal agriculture sector and a burgeoning PBM sector. We constructed a panel of nine experts and employed the Delphi technique during two rounds of an online survey to iteratively assess the degree of consensus and disagreement around the relative priority of 14 possible actions (identified from relevant literature) that could help to scale up the production and/or consumption of PBM in Brazil. We used the Importance, Neglect, and Tractability framework.The panelists collectively concluded that the top priority action for scaling up both the production and the consumption of plant-based meat in Brazil was to reduce the price of products for consumers. For most priority actions, there was greater consensus among panelists in the second round of the survey.Our findings contribute to an improved understanding of (a) which actions may be of highest priority for investors, funders, and policymakers, (b) synergies and differences between priority actions to scale up the production versus consumption of PBM in Brazil, (c) the relative merits of focusing on scaling up PBM production versus consumption, and (d) the strengths and limitations of assessing expert opinion on alternative protein futures using the Delphi technique.

Fibroblasts are important components of animal tissues such as muscle and skin, as they are the major producers of various matrix proteins. Matrix proteins such as collagen play an important role in meat products by providing unique nutrition, texture, and flavor. Cultured meat is an innovative meat alternative produced by culturing animal cells, but currently, relatively few studies have been conducted using fibroblasts as seed cells for cultured meat manufacturing. In this work, we first developed an innovative digestion-friction method for isolating fibroblasts from porcine skin efficiently and cost-effectively. After optimizing the enzymatic digestion and physical friction conditions, 2.39 ± 0.28 × 105 fibroblasts were obtained from 1 cm2 of porcine skin tissue, which was about 9 times higher than the conventional tissue explant method. In addition, we identified an edible bio-ink composed of gelatin and chitosan that has good printing properties and supports fibroblast adhesion and growth. Furthermore, we fabricated fibroblast-based cultured meat by 3D printing with an initial cell density of 1.0 × 107 mL−1 and evaluated its texture and nutritional properties. This work provides valuable insights and references for introducing fibroblasts into the production of cultured meat that is more comparable to structured animal meat.

Microalgae are emerging as a sustainable source of bioproducts, including food, animal feed, nutraceuticals, and biofuels. This review emphasizes the need to carefully select suitable species and highlights the importance of strain optimization to enhance the feasibility of developing algae as a sustainable resource for food and biomaterial production. It discusses microalgal bioprospecting methods, different types of cultivation systems, microalgal biomass yields, and cultivation using wastewater. The paper highlights advances in artificial intelligence that can optimize algal productivity and overcome the limitations faced in current microalgal industries. Additionally, the potential of UV mutagenesis combined with high-throughput screening is examined as a strategy for generating improved strains without introducing foreign genetic material. The necessity of a multifaceted optimization approach for enhanced productivity is acknowledged. This review provides an overview of recent developments crucial for the commercial success of microalgal production.

This study was conducted to understand the variation in the nutrient contents of different types of millets by collecting data from published scientific journals and collating it by variety. The data is analyzed as a whole and as a subset, where it is clearly categorized into a released variety or genotype/accession. Calcium level was consistently high in finger millet and teff regardless of varieties at 331.29 ± 10 mg/100 g and 183.41 ± 29 mg/100 g, respectively. Iron content was highest for finger millet at 12.21 ± 13.69 mg/100 g followed by teff at 11.09 ± 8.35 mg/100 g. Pearl millet contained the highest zinc content of 8.73 ± 11.55 mg/100 g. Protein content was highest in job’s tears at 12.66 g/100 g followed by proso millet at 12.42 ± 1.99 g/100 g and barnyard millet with 12.05 ± 1.77 g/100 g. Some millets showed consistently low or consistently high levels of specific nutrients, while others had such wide variation that they could not be characterized as high or low for that particular nutrient. There is a huge variation in the nutrient content of each type of millet regardless of the released variety or genotype. In the interest of improving dietary nutrients, there is a need to have nutrition programs and product development based on selected high nutrient varieties of the millet, which requires attention from researchers and government and changes in research, policy, and awareness among the public and private sectors.

Digital agricultural marketing platforms have emerged as one of the key tools for facilitating farmers’ access to markets. While previous studies have predominantly focused on examining factors influencing adoption of these platforms, there remains a gap in understanding factors that determine the proportion of a farmer’s produce marketed through the platforms. This knowledge is crucial for effective scaling up of digital marketing platforms. Consequently, this research aimed to evaluate the extent of commercialization of potato farming through Digital Agricultural Marketing Platforms (DAMPs), with a specific focus on the M-shamba platform in Kenya. To achieve this objective, data was collected in 2022 from a sample of 375 potato farmers from Nakuru County. The data was analyzed with Stata using probit and Tobit models through the conditional mixed process. The findings revealed that total farm income, price per kilogram of output, access to credit, size of the farm dedicated to potato cultivation, and age of the household head influenced the use of M-shamba platform. Further, the extent of commercialization through M-shamba was significantly determined by total livestock units, marketing decision-maker, having potato farming as primary enterprise, farm income, access to credit, membership to agricultural groups, and age of the household head. In light of these findings, the study recommends targeted support and training programs for older farmers to enhance their proficiency in utilizing DAMPs. Moreover, policies and initiatives aimed at increasing farm income should be implemented to assist farmers with limited incomes. Farmers in groups should be encouraged to participate in collective digital marketing efforts.
