Globalisation is a key pressure affecting the current and future use of the rangelands of Australia. While primary producers often perceive an insatiable demand for food as a guarantee of business success, declining population growth rates and high levels of productivity improvement in world food production are reducing the importance of food and fibre from the rangelands. This, combined with significant changes in consumer demands, is driving rangeland producers to meet market specifications for quality, safety, animal welfare and sustainability. Sustainability is a particular challenge with the rangelands certain to be affected by global warming and the politics and strategies required to reduce greenhouse gas emissions. Currently the rangelands produce a higher proportion of greenhouse gases compared with their contribution to the economy. However, they also provide an opportunity for carbon sequestration. While international trade liberalisation has been of advantage to the grazing industries in the rangelands, increased global awareness of the Australian rangelands, facilitated by the communications revolution, is encouraging alternative uses including tourism, existence value and other conservation and biodiversity management uses. The growing concept of multi-functionality will also impact on the rangelands as international government programmes continue to encourage non-commercial, surplus production of food. These influences are forcing major changes in the way land is used and what it produces.

Depletion of fossil fuels and global warming could drastically reduce world food production. Conserving and improving rangelands is important, because they likely will play an increased role in meeting world food needs.

In spite of the fact that food production in developing countries doubled over the last 25 years undernutrition is still widely spread. At the beginning of the eighties, according to FAO, 335 to 494 million people in developing countries suffered from serious undernutrition the difference being due to different concepts to determine undernutrition on which scientist were unable to find a consensus.) Unfortunately there is no recent comprehensive analysis of the food situation comparable to those of previous World Food Surveys but it can be taken for sure that the absolute number of undernourished has increased. According to unofficial FAO sources a figure of 870 million was estimated for 1990 (22 percent of the total population in developing countries) using the same concept that led to the figure of 494 million in 1979-81 (23 percent of the total population in developing countries) which means that most probably the number of undernourished increased at a rate slightly less than population growth.

Current social and environmental challenges have led to the rethinking of residential designs. Global warming, food insecurity, and, as a result, costly fresh produce are some of the causes of the reconsideration. Moreover, with obligatory isolation following the global COVID-19 pandemic, some are realizing the importance of nature and air quality in homes. This paper explores the potential integration of indoor living walls (ILWs) in Canadian homes for agricultural and air purification purposes. By reviewing a number of case studies, this paper investigates how the development of such walls can alter the traditional food production chain, while reducing environmental threats. The findings show that current indoor living wall practices can be transformed into a useful source of fresh food, and, to some degree, alter traditional food supply. They can also help in creating inexpensive methods of air purification.

We calculated the rates at which CO2 is being sequestered in two different forest types of Himalaya. For our comparative study we took the degraded and non-degraded sites of pine and oak forests in Kumaun Central Himalaya. The Van Panchayats (VPs) or Community Forests are managing the nondegraded forest sites for centuries, and from this research we have come to know that the sequestration of CO2 in these non-degraded forests is significantly greater than the degraded forests. The paper recommends the significance of community forests in both Uttarakhand and the world, and advocates that if we want to fight against global warming, we must encourage the community forests and that the people living in severe poverty in these forest areas who become the unsung heroes in the war against global warming, must be paid in lieu of saving their forests, which ultimately become the sink for increased CO2 worldwide. This business or ‘carbon trading' will indeed evolve as the panacea against the war against global warming. Key words: Carbon sequestration, community forests, Van Panchayats, green house gases, global warming, carbon trading.   doi: 10.3126/eco.v15i0.1946 ECOPRINT 15: 75-81, 2008
