Breeding crop plants with increased yield potential and improved tolerance to stressful environments is critical for global food security. Drought stress (DS) adversely affects agricultural productivity worldwide expected rise in the coming years. Therefore, it vital understand physiological, biochemical, molecular, ecological mechanisms associated DS. This review examines recent advances plant responses DS expand our understanding of DS-associated mechanisms. Suboptimal water sources affect growth yields through physical impairments, physiological disturbances, biochemical modifications, molecular adjustments. To control devastating effect plants, important its consequences, mechanisms, agronomic genetic basis sustainable production. In addition responses, we highlight several mitigation options such as omics approaches, transgenics breeding, genome editing, mechanical methods (foliar treatments, seed priming, conventional practices). Further, have also presented scope speed breeding platforms helping develop drought-smart future crops. short, recommend incorporating multi-omics, traditional strategies, cultivars achieve 'zero hunger' goal.

Diversifying crop rotation increases food production, reduces net greenhouse gas emissions and improves soil health

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Янв. 3, 2024

Abstract Global food production faces challenges in balancing the need for increased yields with environmental sustainability. This study presents a six-year field experiment North China Plain, demonstrating benefits of diversifying traditional cereal monoculture (wheat–maize) cash crops (sweet potato) and legumes (peanut soybean). The diversified rotations increase equivalent yield by up to 38%, reduce N 2 O emissions 39%, improve system’s greenhouse gas balance 88%. Furthermore, including crop stimulates soil microbial activities, increases organic carbon stocks 8%, enhances health (indexed selected physiochemical biological properties) 45%. large-scale adoption cropping systems Plain could 32% when wheat–maize follows alternative rotation farmer income 20% while benefiting environment. provides an example sustainable practices, emphasizing significance diversification long-term agricultural resilience health.

Sustainable Agro-Food Systems for Addressing Climate Change and Food Security

Agriculture, Год журнала: 2022, Номер 12(10), С. 1554 - 1554

Despite world food production keeping pace with population growth because of the Green Revolution, United Nations (UN) State Food Security and Nutrition in World 2022 Report indicates that number people affected by hunger has increased to 828 million 29.3% global insecure, 22% children under five years age stunted. Many more have low-quality, unhealthy diets micronutrient deficiencies leading obesity, diabetes, other diet-related non-communicable diseases. Additionally, current agro-food systems significantly impact environment climate, including soil water resources. Frequent natural disasters resulting from climate change, pandemics, conflicts weaken exacerbate insecurity worldwide. In this review, we outline knowledge alternative agricultural practices for achieving sustainability as well policies need be implemented an equitable distribution resources several goals UN 2030 Agenda Sustainable Development. According Intergovernmental Panel on Climate Change, animal husbandry, particularly ruminant meat dairy, accounts a significant proportion greenhouse gas (GHG) emissions land use but contributes only 18% energy. contrast, plant-based foods, perennial crops, lowest environmental impacts. Therefore, expanding cultivation perennials, herbaceous replace annual fostering climate-smart choices, implementing subsidies favoring efficient low impact, empowering women, adopting modern biotechnological digital solutions can help transform toward sustainability. There is growing evidence security adequate nutrition achieved using climate-smart, sustainable practices, while reducing negative impacts agriculture, GHG emissions.
