Uncontrolled spatiotemporal changes in large urban areas can produce several problems such as environmental pollution, diminishing valuable agricultural lands; irregular industrialization and urbanization due to number and proportion of residents continue to increase.
Although intensive managed plantations clearly increase the growth and yield of forests several papers refer to declining forest productivity. Therefore in this paper we study the impact of declining forest productivity on the land expectation value and the optimal rotation length.
Land issues, exploitation of natural resources, and Forests of Rural Communities in the periphery of Kinshasa, DRC. Peri-urban forests are under strong anthropic pressure.
Should farming and conservation policies aim broadly to separate land for nature and land for production (land sparing) or integrate production and conservation on the same land (wildlife-friendly farming)?
Soils of the world’s agroecosystems (croplands, grazing lands, rangelands) are depleted of their soil organic carbon (SOC) pool by 25–75% depending on climate, soil type, and historic management. The magnitude of loss may be 10 to 50tonsC/ha.
Agricultural productivity in both developing and developed countries will have to improve to achieve substantial increases in food production by 2050 while land and water resources become less abundant and the effects of climate change introduce much uncertainty.
Local communities often have substantial knowledge related to trends in soil quality and the associated limiting factors.
Recent studies in the literature examining impact of government seed price intervention on adoption of Bt cotton get different results depending on the specifics of the situation analyzed.
The long-term record of global Landsat data is an important resource for studying Earth's system. Given the identified gaps in Landsat data and the undetermined future status of Landsat data availability, alternatives to Landsat imagery need to be tested in an operational environment.
