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...
Conserving biodiversity and ecosystem function through limited development: an empirical evaluation.
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...
natural resources protection not only depends on technology but also on local institutions and organizations. using local organizations like islamic rural councils (ircs) is an alternative to make a proper sustainable organizational framework for managing natural resources as they have the effective role in enhancing rural participation. hence, many countries seek to exhort and use the local pa...
notion of biodiversity and form a concrete definition by which conservationists can define what exactly it is that they value and wish to preserve. A review of biodiversity definitions will accompany a growing and exhaustive list of components which make up the sort of phenomena which create biological variation, resulting ultimately in an inclusive list of biodiversity components and the manne...
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...
nowadays, air pollution is a global problem that has had significant growth by technology development, population growth andindustrial development. industrial development brought natural resources deterioration, more manufacturing products, and more environmental pollutants. if pollutant won’t be controlled, human-being and wildlife will face the critical risks. significant release and critical...
