Die in der Nitratrichtlinie vorgegebenen Ziele für die Qualität des Grundwassers konnten bislang weder in Deutschland insgesamt noch in Rheinland-Pfalz (RP) flächendeckend erreicht werden (BMU und BMEL, 2020). In RP befanden sich 2019/2020 35 der insgesamt 117 Grundwasserkörper in schlechtem...

Biochar is a carbon-rich solid obtained from the heating of biomass in the (near) absence of oxygen in a process called pyrolysis. Its soil incorporation is increasingly discussed as a means to sequester carbon in soils and, thus, to help mitigate climate change. When deployed in agricultural...

Seit einigen Jahren wird Biokohle - ein kohlenstoffreiches Produkt aus Biomasse - als eine viel versprechende Klimaschutzoption diskutiert. Insbesondere besteht die Möglichkeit, der Atmosphäre langfristig Kohlenstoffdioxid zu entziehen, indem Biokohle in den Boden eingearbeitet wird....

Biochar is a carbon-rich solid obtained from the heating of biomass in the (near) absence of oxygen in a process called pyrolysis. Its deployment in soils is increasingly discussed as a promising means to sequester carbon in soils and, thus, to help mitigate climate change. For a wide range of...

To control pests that may damage crops during production, storage or transportation, chemical pesticides are usually used. On the one hand, the use of pesticides can help to reduce yield losses caused by pests, pathogens, and weeds and thereby help feed the world's population; on the other hand,...

This paper investigates the impacts of agricultural technical change on economic diversity of farm households in Vietnam. To develop the empirical analysis, a model is presented in which the estimated impact of agricultural technical changes on economic diversification allows for non-neutral...

Nitrogen management policies introduced in the past decades by some OECD countries have succeeded in reducing excess nitrogen use by farmers, but half of global mineral fertiliser use is still lost for crops. While about half of OECD countries have nutrient surpluses of between 25-50 kg N per...

West African farmers are among those most likely to suffer from climate change, partly due to the agro-climatic characteristics of the regional system and to their limited scope for coping with shocks. Climate change adaptation has thus been touted as a necessary path for rural poverty reduction...

A mix of public policy and market interventions in the mid-2000s led to historic reductions in deforestation in the Brazilian Amazon. The collateral impact of these forest conservation policies on agricultural production is still poorly understood, though evidence is sorely needed given the...

This paper proposed a methodological framework for the assessment of carbon stocks and the development and identification of land use, land use change and land management scenarios, whereby enhancing carbon sequestration synergistically increases biodiversity, the prevention of land degradation...
