Conservation Agriculture is an ecological approach to regenerative sustainable agriculture and ecosystem management based on the practical application of context-specific and locally adapted three interlinked principles of: (i) Continuous no or minimum mechanical soil disturbance (no-till seeding/planting and weeding, and minimum soil disturbance with all other farm operations including harvesting);  (ii) permanent maintenance of soil mulch cover (crop biomass, stubble and cover crops); and (iii) diversification of cropping system (economically, environmentally and socially adapted rotations and/or sequences and/or associations involving annuals and/or perennials, including legumes and cover crops). These practices are complemented with other good agricultural production and land management practices.

Farmer knowledge is key to finding more resilient crops in climate crisis
International Center for Tropical Agriculture (CIAT) via Phys.org
In a review paper published in Frontiers in Plant Science, scientists urge the importance of combining the knowledge harbored by farmers of diverse crop varieties — which is often overlooked by scientists — with high-tech breeding done in laboratories. Authors argue that farmers' knowledge and high-tech breeding to improve crops can be effectively combined to unlock more resilient and nutritious food supplies in the face of climate threats.

Study seeks to increase adoption of soil conservation techniques
South Dakota State University via Aberdeen News
Farmers who make soil health a priority are more likely to rotate three or more crops and to graze livestock on cropland, according to a survey of producers in South Dakota, North Dakota and Nebraska. The survey examined why some agricultural producers prioritize soil health and how to encourage more producers to adopt these conservation practices, according to assistant professor Tong Wang of South Dakota State University's Ness School of Management and Economics.

New freshwater database tells water quality story for 12K lakes globally
York University via Phys.org
Although less than 1% of all water in the world is freshwater, it is what we drink and use for agriculture. In other words, it's vital to human survival. York University researchers have just created a publicly available water quality database for close to 12,000 freshwater lakes globally — almost half of the world's freshwater supply — that will help scientists monitor and manage the health of these lakes.

The world has missed key biodiversity goals — but these 8 changes could make all the difference
World Economic Forum
In 2010, the UN's Convention on Biological Diversity (CBD) set 20 targets to try and slow, then halt the loss of biodiversity. They were agreed in Aichi, Japan. A decade on, its verdict is in — and "business as usual" needs to stop.

Wildfires, logging affect fungi pine forests depend on for survival, studies show
Folio
Disturbances by humans or nature change balance of fungi in soil, potentially making it harder for seedlings to regenerate.

New digital tool provides scientific data and curated insights on conservation farming practices
CSRwire
Scientists from conservation and academic institutions have launched AgEvidence, a visualization dashboard of data from nearly 300 peer-reviewed research papers and curated expert insights derived from those studies. The research compiled in AgEvidence focuses on the environmental and agronomic impacts of cover crops, tillage management, pest management, and nutrient management practices used in growing corn and/or soybean crops in the Midwest.

The most biodiverse places on the planet: Scientists discover secret behind Earth's biodiversity hotspots
SciTechDaily
Researchers have discovered why the tropics and a handful of other areas across the globe have become the most biodiverse places on the planet. The research suggests that biodiversity hotspots — such as the Daintree Rainforest in Australia and the Cloud Forests of Ecuador — are teeming with species because they have been ecologically stable for long periods of time, allowing evolution to forge ahead undisturbed.

Global analysis of how effective and topographic catchment areas differ
University of Freiburg via ScienceDaily
Topographically sketched catchment areas are a spatial unit based on the shapes of the earth's surface. They show how human activities and climate change influence the available quantities of water. Knowledge of these units is fundamental to sustainable water management. However, due to underground connections, some catchment areas accumulate water from areas beyond their topographic boundaries, while others are effectively much smaller than their surface topography would suggest.

Successful soil and nutrient management — healthy soils are better for the environment
The Scottish Farmer
Soils are complex systems that are important in providing and sustaining the landscapes they support. However, they are built up of three main components — physical, chemical and biological and these need to function together to create and maintain this vital resource.

Warming temperatures are driving Arctic greening
NASA/Goddard Space Flight Center via ScienceDaily
As Arctic summers warm, Earth's northern landscapes are changing. Using satellite images to track global tundra ecosystems over decades, a new study found the region has become greener, as warmer air and soil temperatures lead to increased plant growth.
