The recent strategic policy dialogue on the future of agriculture in the European Union focuses on sustainable development and presents a clear challenge to the research community, including soil science. Framing sustainability in the context of the UN Sustainable Development Goals (SDGs), a recent case study is reviewed in this Opinion paper showi...

Soil underpins the functioning of all terrestrial ecosystems. Sustainable soil management is crucial to preventing further degradation of the non-renewable soil resources and achieving sustainability. The soil health concept has gained popularity as a means to this end and has been integrated into the policies of many countries and supranational or...
Article
Full-text available
Current environmental regulations for agriculture in the Netherlands and England focus on the application of certain selected management measures as an empirical basis for providing subsidies. Farmers like this simple, straightforward approach. The link with sustainable development is, however, not defined and this can become problematic when proce...

When considering ecosystem services in line with relevant Sustainable Development Goals, the proposed logical sequence of the ten pedometric challenges can form a framework defining effective contributions by the soil science discipline to the sustainability challenge facing society. Defining relatively simple, but scientifically sound, indicators...

Soil physics defines soil water, air, and temperature regimes that are crucial for agricultural production, the quality of water resources, and waste management. Positioning such activities in the context of the United Nations Sustainable Development Goals (SDGs) will provide a valuable link to the international policy arena and should also include...
Article
Full-text available
The UN Sustainable Development Goals (SDGs) have a deadline of 2030 so, restricting attention to agriculture, development and implementation of management measures, aimed at reaching the goals, is urgent. Even though the current 159 very broad targets and 234 indicators for the SDGs don't mention soils, soils play a key role when addressing indicat...

Full-text available
The previous rather abstract debate about sustainable development has been focused by the introduction of the United Nations (UN) Sustainable Development Goals (SDGs) in 2015 and the related European Union (EU) Green Deal (GD) in 2019. Restricting attention to agriculture, proposed targets and indicators are, however, not specific enough to allow a...
Article
Full-text available
There is general agreement on the need for sustainable development, but the concept has remained rather vague until seventeen specific goals (SDGs) were approved by the UN Assembly in 2015, including targets and indicators. The EU followed this example by introducing their Green Deal in 2019. Soils play a very important role in realizing these goal...
Article
Full-text available
Soil classification is based on both the properties of the soil material and the pedogenetic pathways responsible for those properties. Because soil properties are linked to soil function and potential, information on soil classification has formed the basis for empirical interpretations of mapping units in terms of limitations or suitabilities for...

Pedometrics, the application of mathematical and statistical methods to the study of the distribution and genesis of soils, has broadened its scope over the past two decades. The primary focus of pedometricians has traditionally been on spatial and spatio-temporal soil inventories with numerical soil classification, geostatistical modelling of spat...

Full-text available
The general concept of sustainable development has been specified in terms of goals, targets, and indicators by the UN Sustainable Development Goals, adopted in 2015, followed by the Green Deal of the European Union in 2019. The focus on targets and indicators does, however, not address the issue as to how these goals can be achieved for land-relat...
Article
Being critical to achieving Sustainable Development Goals (SDGs) of the United Nations, strengthening understanding of the properties and processes of soil at national and regional scales is imperative. The necessity to realize SDGs by 2030 also inspires a greater sense of responsibility and care for soils. Sustainable management of soil health is...

The water-soil-waste nexus is more relevant than ever. UN Sustainable Development Goals (SDGs) covering food, water, climate and biodiversity can all significantly be served by applying wastewater and compost to soils, thereby potentially increasing food production, combating water scarcity while higher contents of soil organic matter are effective...
Article
Full-text available
Long a rather abstract concept, sustainable development has since 2015 been defined by the United Nations in terms of goals (SDGs), specified by targets and indicators.Soils play an important role in several land-related SDGs by their contribution to ecosystem services that, in turn, contribute to biomass production (SDG2), water quality (SDG6), cl...
Chapter
Full-text available
This introductory chapter explains why organic waste composting is considered as one of the best examples to demonstrate the benefits of nexus thinking. Current literature is rich with information covering various aspects of composting process. However, it mainly represents two distinct fields: waste from the management point of view and soil/agric...

The seventeen United Nations Sustainable Development Goals (SDGs) present a major challenge to soil scientists that have, so far, not been involved with defining SDG targets and indicators. Soil functioning contributes to ecosystem services (ES) that, in turn, are important to achieve land-related SDGs, including: (1) biomass production (SDG2); (2)...

Since the turn of the millennium, digital soil mapping (DSM) has revolutionized the production of fine resolution gridded soil data with associated uncertainty. However, the link to conventional soil maps has not been sufficiently explained nor are the approaches complementary and synergistic. Further training on the digital soil mapping approaches...

The Available Soil Water Capacity (AWC) is standard data in most soil databases and expresses soil water contents in the rootzone between field capacity (FC; –33 kPa) and permanent wilting point (WP; −1500 kPa). Literature suggests that increasing the content of soil organic matter (SOM) of a given soil does not significantly increase AWC and this...

Soil use and management play a key role, when maintaining or restoring soil quality, as an estimated 30% of soils in the world suffer from various forms of degradation. Several of the seventeen UN Sustainable Development Goals (SDGs), approved in 2015 by 195 governments, are land‐related, providing a stimulating challenge for soil research. Unfortu...

The soil genoform vs. soil phenoform distinction was suggested twenty years ago by Droogers and Bouma to recognize management-induced differences among pedons with the same long-term pedogenesis and included in the same soil map unit, these changes being sufficient to cause important and persistent differences in soil functions. To support the rece...

Assuming that “post-truth” and “fact-free” attitudes are only symptoms of deeper misgivings about “elite” behavior of scientists and lack of understanding of the scientific method, approaches to overcome problems should focus on improved interaction processes and on ways to better illustrate the goals of science. Regarding interaction processes, so...

Soil, through its various functions, plays a vital role in the Earth’s ecosystems and provides multiple ecosystem services to humanity. Pedotransfer functions (PTFs) are simple to complex knowledge rules that relate available soil information to soil properties and variables that are needed to parameterize soil processes. In this paper, we review t...

Dear Wenceslau. Very interesting that approach to follow the movement of nitrate and ammonia in  different cropping systems. I would expect that soil drainage, with the associated nitrification and denitrification processes, will also have significant effects. But perhaps certain crops are only grown at certain soils? I will follow the project as it unfolds. Best wishes, also for the holiday season. Johan Bouma.
