This comprehensive Future Brief from Science for Environment Policy examines the research around ‘impact investment’; those investments which are directed towards generating measurable social and/or environmental impacts, in addition to a financial return. The report focuses on investments in Europe, although it includes a case study of sustainable teak plantation in Panama.

This randomized controlled study looked at how obese Norwegian men were affected by a diet very high in the intake of total and saturated fat, as compared to one high in carbohydrates, while controlling for intake of energy, protein, and polyunsaturated fats and food types. 

This paper in Nature addresses the question of whether a warming planet leads to increased CO2 emissions through heightened activity by soil microbes. It finds that this positive feedback mechanism exists and is likely to be of great importance in the future global carbon budget.

This editorial piece in Environmental Research Letters highlights the fact that, as opposed to CO2 emissions, those of the powerful greenhouse gas methane are currently rising faster than at any point in the last twenty years. Around two-thirds of global emissions of methane are attributable to anthropogenic activities, with agriculture and related land use change identified as a main culprit.

An engineering project aims to produce food, energy and fresh water from solar power and seawater by using a new combination of already established technologies. The Sahara Forest Project is run in desert areas of Qatar, Tunisia and Jordan.

Twenty-four cross-party European parliament members, together with HSI’s Planting Fresh Ideas, wrote a letter to the European Commission President, First Vice President, and Commissioners, with policy recommendations for reducing EU consumption of animal-based foods.

The European Environment Agency has published a report on food systems approaches for the seafood industry in Europe, with the explicit aim of making ‘a first contribution to the collective endeavour of rethinking Europe's food system for sustainability goals’.

In this article co-written by FCRN member Erasmus zu Ermgassen, the authors use what they call a holistic approach (described below) to estimate the GHG emissions savings from preventing UK household food waste. In particular, they include the consideration of a potential rebound effect: the GHG emissions that result from money saved (because of reduced food waste) being spent elsewhere.

In this paper, the authors present an analysis of the nitrogen cycle in the agricultural production system of 12 world regions. From these results, they go on to suggest improvements in nitrogen use by changing the role of human diet, international trade and local production.
