Agricultural scientists at TUM created indicators and models to analyze, assess and optimize the sustainability of agricultural enterprises. The new indicator model describes farms as systems based on their material and energy flows, enabling accurate calculations of emissions, climate balance and biodiversity.
A new study using satellite images found that nearly half of the world's farmed landscapes include significant tree cover, exceeding 10% in over 1 billion hectares. This reveals a vital role of trees in agricultural production globally, providing benefits such as carbon sequestration and nutrition for people.
The region may need to import over a quarter of its rice, wheat and maize if current irrigation management is not improved or innovated. A new study warns that Asia's vast irrigation systems must be revitalized to meet the growing food demand without further straining water resources.
The new grants will study the use and impacts of nitrogen, essential to life but also causing environmental problems such as climate change. The research aims to improve data-collection methods and quantify necessary reductions in nitrous oxide emissions to reduce agricultural pollution.
A Dutch researcher developed an early warning system to monitor food consumption and predict potential shortages in rural Uganda. The system highlights the most pressing issues in a given area at a certain moment in time.
A 110-year-old sustainable farming experiment demonstrates the effectiveness of winter legumes in producing non-irrigated cotton yields, comparable to those using nitrogen fertilizer. The study's findings have implications for long-term soil organic matter and crop yield management.
Scientists estimate that globally up to 4.7 million square kilometers of abandoned lands could be used for sustainable bioenergy production, with a potential yield of nearly half the land area of the United States. The researchers found that biomass from these lands could provide energy equivalent to about 41 exajoules, which would sat...
A panel of industry representatives emphasizes the importance of biotechnology in creating sustainable industries. Key findings include the potential for biomaterials and sustainable industrial processes to reduce reliance on petrochemicals and promote environmentally sound agricultural methods.
Researchers will explore strategies for closing energy and nutrient cycles in small family dairy farms. Initial studies suggest that intensive management of manure, changing bedding methods, and increasing on-site grain production can achieve energy independence and a closed nitrogen system.
A new study reveals that longer, more complex crop rotations increase organic corn yields by 30%, while also improving soybean yields. The results show that diverse crop systems can help address production challenges in organic grain crop production.
A survey of college students revealed mixed opinions on the benefits and drawbacks of biotechnology in sustainable agriculture, with some supporting genetically modified crops and others expressing concerns over environmental and social impacts. The study suggests that educators should provide neutral exposure to both sustainable agric...
A new £7M research initiative aims to improve crop yields and alleviate poverty in developing countries. The Biotechnology and Biological Sciences Research Council is funding 12 projects to develop crops that can survive in harsh environmental conditions, reducing the impact of pests, diseases, and climate change.
The Gates Foundation has launched a $13 million program to support the careers of at least 360 African women in agricultural research. The initiative aims to address the 'leaky pipeline' of women in sub-Saharan Africa, with goals including increasing women's participation in research teams and leadership roles.
Researchers report that sustainable biomass production may be hindered by soil organic matter needs, suggesting a need for alternative crops and improved agricultural practices. The study highlights the importance of considering multiple factors beyond just soil erosion when evaluating feedstock supply.
Researchers explore potential for enhanced nutrient cycling through coupling of agricultural and bioenergy systems to improve sustainability of biomass production. The study reports that up to 78% of nitrogen fertilizer could be recovered from an integrated biological and thermochemical process.
Researchers at Iowa State University have developed a process to turn manure and corn stalks into a bio-oil that can be used as boiler fuel and potentially transportation fuel. Preliminary tests show promising results, with every kilogram of dried mixture producing .2 to .5 kilograms of bio-oil.
A recent study by Esaïe Gandonou found that reducing distance to the market has slight positive effects on grain yields and soil conservation. This is largely due to the increased use of artificial fertilizers, which require soil conservation measures.
A study published in Environmental Science & Technology found that sustainable agriculture practices increased crop yields by an average of 79% across four countries, with harvests of some crops like maize, potatoes, and beans rising by 100%. The practices also reduced pesticide use and increased carbon sequestration.
A Canadian institute has defined sustainable agriculture as a key to ensuring economic viability for farmers. The paper recommends using immigration policies to bolster rural communities and suggests levying a small tax on food to support sustainability goals.
The PLMS system provides instant feedback on alternative grazing systems' impact on farm profit, milk production, and greenhouse gas emissions. A multidisciplinary team is developing the system to balance forage needs with livestock requirements.
Virginia Tech will lead two research projects worth $17 million each, focusing on integrated pest management and sustainable agriculture in developing nations. The projects aim to reduce pesticide use, increase farm income, and promote ecologically sound practices for improved food security.
The ICBG program supports 12 groups in identifying new drugs through screening of flora and fauna while protecting biodiversity. Projects include evaluation of traditional medicine practices, discovery of safe new agents and training for host-country scientific institutions.
The study highlights the environmental and human health problems associated with industrial agriculture, such as soil degradation, water pollution, and increased antibiotic resistance. Sustainable agriculture methods offer a viable alternative, including reducing meat consumption to alleviate pressure on natural resources.
The caiman harvesting program in Venezuela, which began in 1983, has harvested over a million spectacled caimans, generating $115 million in export value. However, the program's direct link to conservation is threatened by changes to funding allocations and market instability.
A 20-year protocol developed by Dr. Charles Peters is applied to dozens of projects, combining exploitation with preservation of biodiversity and ecosystem functions. Local indigenous people in Asia, Africa, and Central/South America are empowered to manage their forests sustainably.
A new RFF issues brief highlights the potential impacts of climate change on agriculture, with estimates suggesting a modest reduction in grain production in developing countries and improvements in industrialized nations. However, the author notes that regional changes are highly uncertain due to varying climate models.
The Cornell University scientists are leading an effort to develop agricultural systems that explicitly improve human health. The new approach, known as a 'food systems' approach, aims to increase the availability of micronutrients like iron in staple crops, reducing illnesses such as heart disease and cancer.
