This paper compared soil moisture and biomass growth between pasture both with and without photovoltaic solar panel arrays. While average soil moisture was similar across the fields with and without solar panels, the field with the solar panels had more variable soil moisture: directly underneath the solar panels, persistent stores of soil water were available throughout the growing season. Without solar panels, the pasture experienced water stress in the middle of summer.
US-based consulting firm Breakthrough Strategies & Solutions has created a list of recent papers, reports, conferences, media items, jobs and other resources on the topics of soil health and soil carbon sequestration.
The Global Partnership on Forest and Landscape Restoration’s report “Restoring forests and landscapes: the key to a sustainable future” presents case studies of the successful restoration of landscapes that have been affected by deforestation and land degradation.
The EU-funded CAPSELLA project, which develops digital tools for agrobiodiversity, has released an online tool to guide users through the steps of taking a “spade test” to monitor soil quality. Users can also choose to upload their results to a public database.
This book, written by the Barilla Center for Food & Nutrition and edited by Danielle Nierenberg of Food Tank, discusses how the global food system can produce sustainable, healthy food for everyone. Topics include soil degradation, water use, barriers to accessing food, corporate influence on dietary choices, and food waste.
This book, by Klaus Lorenz and Rattan Lal, discusses the present state of knowledge on soil carbon dynamics in different types of agricultural systems, including croplands, grasslands, wetlands and agroforestry systems. It also discusses bioenergy and biochar.
A recent paper by FCRN member Roger Leakey of the International Tree Foundation explores the possibility of smallholder farms in Africa using trees and indigenous crops to provide many environmental, social and economic benefits.
The electronic Rothamsted Archive provides data on agricultural experiments (starting in 1843) and weather records (since 1853). A recent paper gives an official account of the history of the archive. The archive includes results of experiments on wheat, permanent grassland, barley, woodland and rotational systems.
A report by WWF, The Rivers Trust and The Angling Trust finds that only 14% of rivers in England are classed as healthy, with damage being caused by poor farming and land management practices, for example by degraded soil being washed into watercourses and agricultural chemicals contaminating groundwater. The report sets out a strategy for managing both soil and water health, including stricter control of slurry storage, incentives for farmers to plant woodland or create wetland habitats and creating an advice service for farmers and land managers.
Land degradation caused by human activities is driving the world towards a sixth mass species extinction, makes climate change worse, has negative impacts on at least 3.2 billion people and costs the world the equivalent of 10% of annual GDP through lost biodiversity and ecosystems services, according to a report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES).
This article evaluates the “4 per 1000” initiative’s potential to increase soil organic carbon (SOC) by assessing 16 long-term soil experiments conducted by the UK based Rothamsted Research, involving 114 different soil treatments (including addition of farmyard manure (FYM), nitrogen fertilisers, pasture leys, conversion of arable land into woodland and residue incorporation) over 7–157 years.
UK farmers may be given targets to reverse soil damage and restore soil health by 2030, as part of an agricultural bill to be brought before parliament later this year.
In this paper, researchers from the Joint Research Centre of the European Commission investigate the extent to which variation in nitrous oxide (N2O) emissions may offset or enhance the mitigation effects of carbon sequestration in arable European soils. They employ a biogeochemical model with input data from ~8000 soil sampling locations to quantify CO2 and N2O flux associated with different agricultural practices aimed at carbon (C) mitigation.
Scotland’s soils contain over half of the UK’s soil carbon stock, making it important to know how to avoid soil carbon loss. The Scottish landscape is currently a net sink for carbon (mainly due to forestry). A recent report assesses current knowledge on soil carbon and land use in Scotland.
This report from the International Centre for Tropical Agriculture (CIAT) considers the relationships between land use, land degradation and sustainable development goals.
This article presents the results from a new global soil erosion model, based on a combination of remote sensing, GIS modelling and census data. It finds that accelerated soil erosion due to land use change between 2001 and 2012 is a major threat to soil and future agriculture but that previous commonly used estimates of annual global soil erosion were twice too high. In comparison with previous studies which had a mapping resolution of around 10–60 km cell size, this model with its high-resolution 250m cell size has far greater predictive power than any previous model.
