Until now, the international community has made tireless efforts to get public attention and political action on issues of desertification, land degradation and drought (DLDD) with limited success.
To assess sustainability of rural management in the Changjiang River basin, human behavioral (food consumption, lifestyle pattern, and human waste disposal) impact on nitrogen flow was quantitatively evaluated. A survey of day-to-day activities was conducted in two representative counties: Taoyuan and Taihe.
In European mountain areas, shrub encroachment resulting from farmland abandonment is most often managed by mechanical operations such as roller chopping or controlled burning, which have proved to be ineffective and unsustainable. Recent agroecological findings highlight the potential impact of grazing on long-term shrub dynamics.
The implicit hydrologic dimensions of international efforts to mitigate climate change, specifically potential impacts of the Clean Development Mechanism-Afforestation/Reforestation (CDM-AR) provisions of the Kyoto Protocol (KP) on global, regional and local water cycles, are examined.
Although Indonesia has no shortage of land area that lost its forest cover before 1990 and has become the global leader in land-use based greenhouse gas emissions, the widespread expectation that the afforestation/reforestation approach to Clean Development Mechanisms (A/R CDM) could lead to sustainable development benefits has not so far materialized.
Smallholders in many tropical highlands cause serious environmental damage. The Cameron Highlands of Malaysia offer an excellent opportunity for studying how farmers interact with environment, changing markets, infrastructure development, indigenous peoples, and tourism, and how these shape innovation.
Tropical countries face special specific problems in implementing sustainable forest management (SFM). In many countries, questions are raised on whether tropical forests should be publicly, commonly or privately owned and managed in order to enhance sustainability.
In European mountain areas, shrub encroachment resulting from farmland abandonment is most often managed by mechanical operations such as roller chopping or controlled burning, which have proved to be ineffective and unsustainable. Recent agroecological findings highlight the potential impact of grazing on long-term shrub dynamics.
Market mechanisms for forest environmental services are increasingly used for promoting environmental conservation, and their impacts on development are of considerable interest. In Costa Rica a national scheme of Payment for Environmental Services (PSA) rewards landowners for the services provided by different forest land-uses.
Water cycle, land management, and environmental sustainability are intimately linked. Sustainable land and water management practices are vital for sustaining agricultural productivity and regional development.
The promise of the Clean Development Mechanism (CDM) to deliver its dual objectives is currently under public scrutiny. In land-use, land-use change and forestry (LULUCF) activities through afforestation and reforestation projects, known as A/R CDM, the deliverables that demonstrate sustainable development remain unclear.
Expanding human population and economic growth have led to large-scale conversion of natural habitat to human-dominated landscapes with consequent large-scale declines in biodiversity. Conserving biodiversity, while at the same time meeting expanding human needs, is an issue of utmost importance.
