Natural resources - Essay Example The world is faces with a challenge to guarantee the lasting utilization of natural resources at the lowest possible environmental cost while still assuring economic and social development. Natural Resources & Environment (NRE) is a broad emphasis area with major impact on the quality of our world. NRE programs strengthen the nation's capacity to address critical environmental priorities and contribute to improved air, soil, and water quality; fish and wildlife management; enhanced aquatic and other ecosystems; the sustainable use and management of forests, rangelands, watersheds, and other renewable natural resources; and a better understanding of global climate change, including its impact on the diversity of plant and animal life. These programs also demonstrate the benefits and opportunities of sustainable development, and contribute to the economic viability of agriculture and rural communities and realizing the impact of environmental policies and regulations. The sustainability of natural resources immensely depends on the use and management decisions of individual private landowners, who have a collective control over more than two-thirds of the nation's land and water resources. As agriculture is no longer the largest element in the economic base of most rural communities, natural resource wealth and income opportunities are becoming more important to farmers, ranchers, other landowners, and communities. Pressures on land and natural resource use are becoming more and more competing and conflicting.. Public demand keeps growing for natural resource products, services, and improved environmental quality. On the other hand, changing demographics and social values bring new challenges. Urbanization has serious impacts on ecosystem structure and function and they are becoming increasingly fragmented for the production of food and forest products. The goal should aim at discovering new, improved ways to use and manage natural resources and educational programs that teach best management practices will enhance environmental and economic benefits, as well as human well-being. These are critical ecological strategies are investments for our future Outline a process by which you could determine primary gross and net productivity, use data to support your process. The term "Production" implies to the creation of new organic matter. When a plant grows, new organic matter is created by the process of photosynthesis, which converts light energy into energy stored in chemical bonds within plant tissue. This energy fuels the metabolic machinery of the plant. New compounds and structures are synthesized, cells divide, and the plant grows in size. When we attempt to measure the rate at which photosynthesis occurs, or the rate at which the individual plant increases in mass, we are concerned with primary production (definition: the synthesis and storage of organic molecules during the growth and reproduction of photosynthetic organisms). * Gross Primary Production, GPP, is the total amount of CO2 that is fixed by the plant in photosynthesis. * Respiration, R, is the amount of CO2 that is lost from an organism or system from metabolic activity. Respiration can be further divided into components that reflect the source of the CO2. Rp =Respiration by Plants Rh = Respiration by Heterotrophs Rd = Respiration by
