In previous papers we have considered the optimal mix of biodiversity in semi-arid rangelands, focusing on the steady … trajectory of biodiversity change. There are two issues involved in the question of timing. One is the uncertainty associated …

values, carbon sequestration and biodiversity or scenic values. We solve the model qualitatively with general functions and … sequestration may have negative impacts on biodiversity-scenic values. To evaluate the practical relevance, we compare …

productivity. However, this is not the only channel for climatic change to affect agro-systems. Biodiversity is subject to climatic … fluctuations and in turn may alter land productivity too. Firstly, biodiversity is an input into agro-ecosystems. Secondly …, biodiversity supports the functioning of these systems (e.g. the balancing of the nutrient cycle). Thirdly, agro-systems also host …

This work examines the impact that economic growth can have on biodiversity and on the ecological dynamics that would … naturally emerge in the absence of human activity. The loss of biodiversity may induce policy-makers to implement defensive … exist in the absence of human intervention. This suggests that there might exist a conflict between preserving biodiversity …

But as … emission from deforestation as well as biodiversity are threatened by further and inevitable land use change. Increasing yields … adaptation to climate change, help to combat deforestation and desertification, better preserve biodiversity, and ultimately also …
