Decision-Making in Agriculture: Why do Farmers Decide to Adopt a New Practice?
Current rates of environmental degradation demand changes to the way in which food is produced. Transforming agricultural production requires both the development and the adoption of new practices that facilitate high yields at least environmental cost. Many beneficial practices have already been …

Stochastic Methods for Setting Effective Aviation NOₓ Policies
… for the combined climate and air quality cost of NOₓ from aviation cruise emissions is estimated as ∼$95,000/tonne using a 2019 flight inventory. Then, cruise limits are proposed informed by the combined impact of NOₓ and CO₂ at cruise and with a similar slope to the current LTO standard. …

Social aspects of natural resource management in rural Kwazulu
Environmental degradation is widely regarded as an integral part of South Africa's homeland areas. Conventional thinking often blames so-called traditional farming practices, attitudes and values for this situation. In other words, the blame is placed with the residents of the areas and …
