Displaying 226 - 230 of 284Drought tolerant species dominate as rainfall and tree cover returns in the West African Sahel
After the severe droughts in the 1970s and 1980s, and subsequent debates about desertification, analyses of satellite images reveal that the West African Sahel has become greener again. In this paper we report a study on changes in tree cover and tree species composition in three village landscapes in northern Burkina Faso, based on a combination of methods: tree density change detection using aerial photos and satellite images, a tree species inventory including size class distribution analysis, and interviews with local farmers about woody vegetation changes.
A causal analysis framework for land-use change and the potential role of bioenergy policy
We propose a causal analysis framework to increase understanding of land-use change (LUC) and the reliability of LUC models. This health-sciences-inspired framework can be applied to determine probable causes of LUC in the context of bioenergy. Calculations of net greenhouse gas (GHG) emissions for LUC associated with biofuel production are critical in determining whether a fuel qualifies as a biofuel or advanced biofuel category under regional (EU), national (US, UK), and state (California) regulations.
Attitudes of a farming community towards urban growth and rural fragmentation—An Auckland case study
As the global population continues to increase, rural areas are expected to accommodate future growth at the same time as continuing to feed growing populations. This tension is greatest on those who farm land that is earmarked for future urban growth. Yet, little is known about the attitudes and values of the affected rural farming communities or farmers’ perceptions of the challenges and opportunities that population growth presents.
Towards productive landscapes: Trade-offs in tree-cover and income across a matrix of smallholder agricultural land-use systems
One of the main causes of tropical forest loss is conversion to agriculture, which is constantly increasing as a dominant land cover in the tropics. The loss of forests greatly affects biodiversity and ecosystem services. This paper assesses the economic return from increasing tree cover in agricultural landscapes in two tropical locations, West Java, Indonesia and eastern Bangladesh. Agroforestry systems are compared with subsistence seasonal food-crop-based agricultural systems.
Supplying trees in an era of environmental uncertainty: Identifying challenges faced by the forest nursery sector in Great Britain
In recent years, numerous articles have addressed management strategies aimed at assisting forests to adapt to climate change. However, these seldom take into account the practical and economic implications of implementing these strategies, notably, supply of forest plants and seed.
