Towards Climate-Smart Agriculture: Strategies for Sustainable Agricultural Production, Food Security, and Greenhouse Gas Reduction

Agronomy, Journal Year: 2025, Volume and Issue: 15(3), P. 565 - 565

Published: Feb. 25, 2025

Without transformative adaptation strategies, the impact of climate change is projected to reduce global crop yields and increase food insecurity, while rising greenhouse gas (GHG) emissions further exacerbate crisis. While agriculture a major contributor through unsustainable practices, it also offers significant opportunities mitigate these adoption sustainable practices. This review examines climate-smart (CSA) as key strategy for enhancing productivity, building resilience, reducing GHG emissions, emphasizing need strategic interventions accelerate its large-scale implementation improved security. The analysis revealed that nitrogen use efficiency (NUE) has in developed countries, NUE remains at 55.47%, precision nutrient management integrated soil fertility strategies enhance productivity minimize environmental impacts. With 40% world’s agricultural land already degraded, sustainability alone insufficient, necessitating shift toward regenerative practices restore degraded water by improving health, biodiversity, increasing carbon sequestration, thus ensuring long-term resilience. CSA including agriculture, biochar application, agroforestry, improve security, emissions. However, result variability highlights site-specific optimize benefits. Integrating multiple enhances health more effectively than implementing single practice alone. Widespread faces socio-economic technological barriers, requiring supportive policies, financial incentives, capacity-building initiatives. By adopting technologies, can transition sustainability, securing systems addressing challenges.

Machine learning in nutrient management: A review

Artificial Intelligence in Agriculture, Journal Year: 2023, Volume and Issue: 9, P. 1 - 11

Published: June 20, 2023

In agriculture, precise fertilization and effective nutrient management are critical. Machine learning (ML) has recently been increasingly used to develop decision support tools for modern agricultural systems, including management, improve yields while reducing expenses environmental impact. ML based systems require huge amounts of data from different platforms handle non-linear tasks build predictive models that can productivity. This study reviews machine techniques estimating fertilizer status have developed in the last decade. A thorough investigation detection classification approaches was conducted, which served as basis a detailed assessment key challenges remain be addressed. The research findings suggest rapid improvements sensor technology provide cost-effective decision-making solutions. Future directions also recommended practical application this technology.

Spatially differentiated nitrogen supply is key in a global food–fertilizer price crisis

Nature Sustainability, Journal Year: 2023, Volume and Issue: 6(10), P. 1268 - 1278

Published: June 29, 2023

Abstract A regional geopolitical conflict and sudden massive supply disruptions have revealed vulnerabilities in our global fuel–fertilizer–food nexus. As nitrogen (N) fertilizer price spikes threaten food security, differentiated responses are required to maintain staple cereal yields across over- underfertilized agricultural systems. Through integrated management of organic inorganic N sources high- low-input production systems, we estimate potential total N-fertilizer savings 11% India, 49% Ethiopia 44% Malawi. Shifting more cost-effective, high-N (such as urea), combined with compost integration legumes, can optimize N-deficient Better targeted efficient use will benefit systems surplus N. Geospatially fertilization strategies should prioritize low-yield, locations balanced N, P, K micronutrients high-yield Nationally, governments invest extension realign subsidies enable incentivize improved at the farm level.

Status quo and challenges of rice production in sub-Saharan Africa

Plant Production Science, Journal Year: 2023, Volume and Issue: 26(3), P. 320 - 333

Published: July 3, 2023

Rice production in sub-Saharan Africa (SSA) has increaed ten-fold since 1961, whereas its consumption exceeded the and regional self-sufficiency rate is only 48% 2020. Increase rice come mainly from increased harvested area. Yield increase been limited current average yield SSA around 2 t ha−1. This paper aims to provide status quo of (i) challenges, (ii) selected achievements agronomy research by Center partners, (iii) perspectives for future on SSA. The major problems confronting include low rainfed environments, accounting 70% total Rainfed yields are strongly affected climate extremes such as water stresses, soil-related constraints, sub-optimum natural resource management crop practices smallholder farmers including poor management, suboptimal use fertilizers, herbicides, machineries. For alleviating these a wide range technologies have developed introduced over last three decades. These conservation irrigated lowland rice, site-specific nutrient practices, decision support tools growth simulation models, labor-saving technologies. We conclude that further efforts needed develop locally adapted agronomic solutions sustainable intensification, especially enhance resilience change land labor productivity sustainability cultivation
