Agrobiodiversity is a common resource, on which our future global food security rest, while simultaneously representing the means of survival for many local farmers at present. Women have been identified as the key-persons regarding knowledge and management skills to use and thereby conserve biological diversity in agriculture. The Indian Government has introduced the “Protection of Plant Varie...

Suburban, exurban, and rural development in the United States consumes nearly 1 million hectares of land per year and is a leading threat to biodiversity. In response to this threat, conservation development has been advanced as a way to combine land development and land conservation while providing functional protection for natural resources. Yet, although conservation development techniques h...

Biodiversity data are rapidly becoming available over the Internet in common formats that promote sharing and exchange. Currently, these data are somewhat problematic, primarily with regard to geographic and taxonomic accuracy, for use in ecological research, natural resources management and conservation decision-making. However, web-based georeferencing tools that utilize best practices and ga...

Human population growth and the consequent increase in use of natural resources place enormous stress on ecosystems. Road building, urbanization and agriculture are among the main human activities that break up natural areas, often with disastrous consequences for wildlife. Concern about threats to biodiversity is reflected in the continuous increase in the number and size of protected areas wo...

Nepal is small geographically, but is an important centre of agricultural biodiversity. The rich Nepalese agro-biodiversity has evolved over time and space due to extreme variations in altitude and environmental conditions. Crop production takes place between 70 to 3000 m elevation where a wide range of micro-ecological niches are found, and varied crop production systems are being practiced by...

Managing ecosystems for carbon storage may also benefit biodiversity conservation, but such a potential 'win-win' scenario has not yet been assessed for tropical agroforestry landscapes. We measured above- and below-ground carbon stocks as well as the species richness of four groups of plants and eight of animals on 14 representative plots in Sulawesi, Indonesia, ranging from natural rainforest...
