Confronting sustainable intensification with uncertainty and extreme values on smallholder tropical farms

Smallholder Farms and the Potential for Sustainable Intensification

The sustainable intensification of African agriculture is gaining momentum with the compelling need to increase food and agricultural production. In Southern Africa, smallholder farming systems are predominately maize-based and subject to erratic climatic conditions. Farmer crop and soil management decisions are influenced by a plethora of complex factors such as market access resource availabi...

Evaluating the Sustainable Intensification of arable farms.

Sustainable Intensification (SI) of agriculture has recently received widespread political attention, in both the UK and internationally. The concept recognises the need to simultaneously raise yields, increase input use efficiency and reduce the negative environmental impacts of farming systems to secure future food production and to sustainably use the limited resources for agriculture. The o...

Sustainable Intensification of Tropical Agro-Ecosystems: Need and Potentials

Rapid population growth, increasingly complex economies and novel industrial uses of agricultural products call for further intensification of agriculture, particularly in the tropics. How to achieve sustainable intensification of food production systems in tropical regions that are challenged by ongoing climate change, loss of natural resources and biodiversity is a matter of debate. Here we h...

Chemical Trees with Extreme Values of Zagreb Indices and Coindices

We give sharp upper bounds on the Zagreb indices and lower bounds on the Zagreb coindices of chemical trees and characterize the case of equality for each of these topological invariants.
