Smallholder farmers play a crucial role in global agricultural development. The digital transformation of smallholder agriculture can enhance productivity, increase farmers’ income, ensure food security, and promote sustainable rural However, existing studies often fail to analyze the holistic nature this lack systematic review relevant literature. Therefore, study aims provide comprehensive presentation current on through logical synthesis reflective summarization, thereby offering valuable academic insights practical guidance for farming. This constructs an analytical framework centered “government–technology–smallholders” using literature methodology, systematically examining main practices, challenges, future strategies agriculture. Our reveals that practices primarily focus production, e-commerce, information exchange. We identify key challenges at government, technical, levels, including inadequate policies, limited availability applications, difficulties adapting uniform technologies diverse contexts smallholders, insufficient resources endowment among farmers, significant group disparities, constraints imposed by social cultural factors. To agriculture, it is essential improve supply policy resources, attention responsiveness toward needs, refine governance policies. Additionally, we must develop user-friendly applications cater varied needs reduce access costs, literacy, foster inclusive environment development, respect integrate communities. deepens understanding provides theoretical policymakers, technology developers, It contributes development supports revitalization shared prosperity.

Can site-specific nutrient management improve the productivity and resource use efficiency of climate-resilient finger millet in calcareous soils in India?

Heliyon, Journal Year: 2024, Volume and Issue: 10(12), P. e32774 - e32774

Published: June 1, 2024

Finger millet, an important 'Nutri-Cereal' and climate-resilient crop, is cultivated as a marginal crop in calcareous soils. Calcareous soils have low organic carbon content, high pH levels, poor structure. Such situation leads to productivity of the crop. Site-specific nutrient management (SSNM), which focuses on supplying optimum nutrients when needed, can ensure production improve energy use efficiency crops. Moreover, developing appropriate SSNM technique for this could offer new insights into practices, particularly A field experiment was conducted during rainy seasons 2020 2021 soil at Dr. Rajendra Prasad Central Agricultural University, Pusa, India.

Evaluation of Low-Cost Multi-Spectral Sensors for Measuring Chlorophyll Levels Across Diverse Leaf Types

Sensors, Journal Year: 2025, Volume and Issue: 25(7), P. 2198 - 2198

Published: March 31, 2025

Chlorophyll levels are a key indicator of plant nitrogen status, which plays critical role in optimizing agricultural yields. This study evaluated the performance three low-cost multi-spectral sensors, AS7262, AS7263, and AS7265x, for non-destructive chlorophyll measurement. Measurements were taken from diverse set five leaf types, including smooth, uniform leaves (banana mango), textured (jasmine sugarcane), narrow (rice). Partial least squares regression models used to fit sensor spectra levels, using nested cross-validation ensure robust model evaluation. Sensor was assessed R2 mean absolute error (MAE) scores. The AS7265x demonstrated best on with validation scores 0.96-0.95. Its decreased other leaves, 0.75-0.85. AS7262 AS7263 while slightly less accurate, achieved reasonable ranging 0.93 0.86 smooth 0.85 0.73 leaves. All particularly show potential measurement applications. Their low cost accuracy make them suitable applications such as monitoring levels.

“Sedentarisation” of transhumant pastoralists results in privatization of resources and soil fertility decline in West Africa's cotton belt

Frontiers in Sustainable Food Systems, Journal Year: 2023, Volume and Issue: 7

Published: Feb. 13, 2023

Transhumant pastoralism is an ancient natural resource management system traditionally connecting ecosystems across north-south precipitation gradients in West Africa. As rural population grew, several governments the region have promoted their settlement, i.e., “sedentarisation” of nomadic pastoral peoples to avoid conflict over land use and access resources with local sedentary populations. Former transhumant pastoralists settled down started growing crops using manure livestock. This led dwindling traditional agreements exchanges (manure against crop residues) between agriculturalists, that resulted less nutrients flowing livestock, food main cash region: cotton. a consequence, soil fertility declined, grazing areas are overexploited, production increasingly dependent on mineral fertilizers, which produced outside region, exposing livelihood farmers volatility international (oil) markets. How do perceive effect this virtual “privatization” resources? Is cotton, agricultural export west African countries, viable option new situation? What does imply for research policy agendas support development? We explored these questions through engaging discussion farmers, herders extension agents three cotton zones Benin.
