Practical Ways to Assess Sustainability

Agroscope has developed the foundation of a methodology for assessing the sustainability of Swiss farms. From summer 2016, a set of indicators will be tested on around ten farms. Sustainably managed farms form an important basis for healthy, fit-for-the-future food production.

The assessment of a farm’s sustainability is a vital step in its optimisation. Here, equal consideration must be given to the criteria concerning the three dimensions of environment, economy and society. Agroscope has developed appropriate indicators, and published these in May 2016 in the ‘Agroscope Science’ publication series.

These indicators are the foundation for enabling farmers, consumers and associations as well as interested actors and stakeholders from production, processing and trade to develop a comprehensive farm sustainability assessment. Particular attention is devoted by Agroscope to the social dimension. This field still lacks sufficient resilient and practical indicators that are tailor-made for Swiss farms.

Well-being concept for human well-being

Four project teams developed indicators for assessing social sustainability, with a focus on the three areas of human well-being, animal welfare, and landscape aesthetics. Here, it was shown that the Well-being Concept of the Organization for Economic Cooperation and Development (OECD) represents a good basis for depicting the various aspects of human well-being. To this end, key questions allowing the relevant topics to be described simply and concisely were developed for each sub-aspect such as e.g. work/life balance, social relationships and subjective well-being. 

Owing to the relevance of the topic for agriculture, a project team devoted itself to the calculation of temporal workload. On the basis of the ‘ART Work Budget’ software developed by Agroscope to calculate the expected working time, we derived an indicator by comparing the theoretically derived working-time input and the workforce available on the farm. 

Point system for animal welfare

A further project team noted that using a simple indicator to assess animal welfare cannot cover all of the requirements. The researchers therefore propose a point system that manages without observations or measurements on the animal itself. In this system, points are awarded to measures with an anticipated positive impact on one of the twelve animal welfare aspects taken into account in the existing Welfare®-Quality Protocol measuring instrument, e.g. freedom of movement or the absence of pain.  In order for points to be awarded, the anticipated animal welfare must go beyond the minimum stipulated in the Swiss Animal Protection Law. Follow-up projects will now aim to determine whether a correlation does in fact exist between the number of points awarded and the level of animal welfare.

Indicators for the economy and environment

Agroscope has also developed indicators for the economic and environmental dimensions; detailed information on these can be found in the relevant Agroscope publication of May 2016. The economic sustainability of a farm can be illustrated by two key figures in each of the following areas: profitability (earned income per family labour unit and total return on capital); liquidity (cashflow-turnover rate and dynamic gearing ratio), and stability (investment intensity and investment coverage). The environmental dimension of sustainability encompasses the components of resource efficiency, effects on climate, nutrients, and ecotoxicity, as well as biodiversity and soil quality. 

Practicability, utility, acceptance

Practical testing of the indicator set is carried out in close cooperation with the involved farmers. The test determines the practicability, utility and acceptance of a sustainability assessment at farm level. In addition to the refinement of the indicator set, a scientific analysis of the results is planned. The project will be concluded with an in-depth report at the end of 2019. The results obtained are meant to contribute to the implementation of a practical solution for assessing sustainability on a large number of farms. The project is financially supported by the Migros Cooperative Association (MGB). IP-Suisse is actively involved in data acquisition.

Activities

Natural toxins comprise a highly diverse group of toxic compounds produced by either animals, algae, bacteria, fungi or plants that are to a great extent not yet commonly regarded as environmental contaminants of concern for water quality. However, as studies on the occurrence, distribution and transformation processes of natural toxins in the environment are generally scarce, effective environmental risk assessment is difficult and the degree of background toxicity to aqueous ecosystems caused by natural toxins unknown.

Aquatic fate and mobility of any organic compound in the environment can be systematically and quantitatively described by distribution coefficients such as those defining octanol-water partitioning and sorption processes. Up to now, hardly any data defining those key parameters for natural toxins is available and in silico prediction tools show limited applicability for multifunctional organics as they are found within this group of chemicals. This stresses the urgent need for reliable, robust methods for high-throughput determination of physico-chemical properties as basis for profound environmental risk assessment.

Therefore, this project aims to establish HPLC-based high-throughput methods for property determination for a wide range of natural toxins. Subsequently, generated data will help to validate and calibrate prediction models for parameter estimation. The outcome of this project will also provide first indications on those phytotoxins that should be further considered and investigated as part of the complex mixture of micropollutants affecting water quality.

This project is part of the European Training Network “Natural Toxins and Drinking Water Quality - From Source to Tap” (NaToxAq) funded by the European Union’s Horizon 2020 research and innovation program. As a whole, NaToxAq aims to obtain a deep insight on natural toxins as environmental contaminants to ensure the production of clean drinking water.
