Agriculture, Journal Year: 2023, Volume and Issue: 13(1), P. 225 - 225

Published: Jan. 16, 2023

Although agriculture remains the dominant economic activity in many countries around world, recent years this sector has continued to be negatively impacted by climate change leading food insecurities. This is so because extreme weather conditions induced are detrimental most crops and affect expected quantity of agricultural production. there no way fully mitigate these natural phenomena, it could much better if information known earlier about future that farmers can plan accordingly. Early sharing crop production may support insecurity risk reduction. In regard, work employs data mining techniques predict (i.e., Irish potatoes Maize) harvests using yields historical for Musanze, a district Rwanda. The study applies machine learning based on communicate trends. Weather maize were gathered from various sources. collected analyzed through Random Forest, Polynomial Regression, Support Vector Regressor.

Adaptation of Agriculture to Climate Change: A Scoping Review

Climate, Journal Year: 2023, Volume and Issue: 11(10), P. 202 - 202

Published: Oct. 6, 2023

Since agricultural productivity is weather and climate-related fundamentally depends on climate stability, change poses many diverse challenges to activities. The objective of this study review adaptation strategies interventions in countries around the world proposed for implementation reduce impact development production at various spatial scales. A literature search was conducted June–August 2023 using electronic databases Google Scholar Scientific Electronic Library eLibrary.RU, seeking key words “climate”, “climate change”, “agriculture adaptation”. Sixty-five studies were identified selected review. negative impacts are expressed terms reduced crop yields area, biotic abiotic factors, economic losses, increased labor, equipment costs. Strategies actions that can be emphasized local regional levels are: varieties management, including land use innovative breeding techniques; water soil agronomic practices; farmer training knowledge transfer; national levels: financial schemes, insurance, migration, culture; meteorological services; R&D, early warning systems. Adaptation depend context, region, or country; limiting discussion options measures only one type approach—"top-down” “bottom-up”—may lead unsatisfactory solutions those areas most affected by but with few resources adapt it. Biodiversity-based, “ecologically intensive” agriculture, climate-smart agriculture low-impact strong ecological modernization aiming sustainably increase incomes while addressing interrelated food security. Some taken response may not sufficient even vulnerability change. Future research should focus explore readiness farmers society adopt new constraints they face, as well main factors affecting them, order detect maladaptation before it occurs.

Mechanistic Understanding of Leakage and Consequences and Recent Technological Advances in Improving Nitrogen Use Efficiency in Cereals

Agronomy, Journal Year: 2023, Volume and Issue: 13(2), P. 527 - 527

Published: Feb. 11, 2023

Although nitrogen (N) is the most limiting nutrient for agricultural production, its overuse associated with environmental pollution, increased concentration of greenhouse gases, and several human animal health implications. These implications are greatly affected by biochemical transformations losses N such as volatilization, leaching, runoff, denitrification. Half globally produced fertilizers used to grow three major cereals—rice, wheat, maize—and their current level recovery approximately 30–50%. The continuously increasing application fertilizers, despite lower cereals, can further intensify leftover N. To address these implications, improvement in use efficiency (NUE) adopting efficient agronomic practices modern breeding biotechnological tools developing cultivars requires immediate attention. Conventional marker-assisted selection methods be map quantitative trait loci, introgression elite germplasm leads creation better NUE.

‘Against all floods’: plant adaptation to flooding stress and combined abiotic stresses

The Plant Journal, Journal Year: 2024, Volume and Issue: 117(6), P. 1836 - 1855

Published: Jan. 13, 2024

SUMMARY Current climate change brings with it a higher frequency of environmental stresses, which occur in combination rather than individually leading to massive crop losses worldwide. In addition to, for example, drought stress (low water availability), also flooding (excessive water) can threaten the plant, causing, among others, an energy crisis due hypoxia, is responded by extensive transcriptional, metabolic and growth‐related adaptations. While signalling during relatively well understood, at least model plants, molecular mechanisms combinatorial responses, simultaneously salinity, temperature heavy metal or sequentially stress, remain elusive. This represents significant gap knowledge fact that dually stressed plants often show unique responses multiple levels not observed under single stress. this review, we (i) consider possible effects combinations from theoretical point view, (ii) summarize current state on signal transduction (iii) describe plant adaptation combined four other abiotic stresses (iv) propose components (hypoxia) based their reported dual roles stresses. way, more future emphasis may be placed deciphering adaptation, thereby potentially stimulating development tools improve resilience towards multi‐stress scenarios.
