a. How does in-situ promote the biodiversity conservation?
b. Greater biodiversity increases the stability of the ecosystem. Justify.
C. How does global warming cause loss of biodiversity?
d. What are some of the economic benefits of the biodiversity?
e. Explain the importance of traditional practices in biodiversity conservation?
Answers
Explanation:
a. In Situ Conservation Techniques. In situ conservation involves the maintenance of genetic variation at the location where it is encountered, either in the wild or in traditional farming systems. The three main in situ techniques may be broadly defined as genetic reserve, on-farm, and home garden conservation.
b. Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
c. Climate change can affect species in myriad ways including the expansion, contraction, and “migration” of habitat; increased incidence of disease and invasive species; changes in temperature, precipitation, and other environmental conditions; shifts in food availability;
d. Biodiversity Underpins Economic Activity
Food production relies on biodiversity for a variety of food plants, pollination, pest control, nutrient provision, genetic diversity, and disease prevention and control. Both medicinal plants and manufactured pharmaceuticals rely on biodiversity.
e. Community participation is key to sustainable management of biodiversity including mangroves, which are getting degraded due to hydrological and geomorphologic changes and the management practice of clear-felling. Fishermen use mangroves for fuelwood, house construction, thatching, grazing, fencing and fishing poles.
