India's heritage of natural habitats and wild species is under growing threat from its biomass-dependent rural peoples and its consumeristic urban economy. As the mainstay of its wildlife conservation effort, then, India's wildlife reserves continue to face a range of extractive uses.

The authors analyzed the dynamics of greenhouse gas (GHG) emissions from household fuel use in sub-Saharan Africa from 2000 to 2050. The scenarios included a business-as-usual (BAU) scenario, in which fuel consumption and tree-harvesting practices change little except through population growth and urbanization, and large-scale shifts to charcoal- and petroleum-based fossil fuels.

The rice-wheat annual double cropping system occupies an estimated 0.5 million hectares in Nepal where it provides food for about 23 million people. Current production levels of both rice and wheat are far below their reported potential with N-deficiency being the major production constraint.

According to IEA’s factsheet, Renewables in global energy supply, the wind energy sector has grown at more than 52 per cent per annum since 1971, and solar power by 32 per cent per annum.

At Renewables 2004 "an international action plan will be on the agenda, including actions and commitments by governments, international organisations and stakeholders,' says the conference

Starting before industrialised Germany and the UK, India has perhaps promoted renewables the longest though a dedicated establishment. The country's Ministry of Non-conventional Energy Sources (MNES) is one of its kind in the world. India has the fifth largest installed wind capacity in the world at 2400 MW. In 2003 alone, India added 615 MW of wind energy. By March 2003, it had 484 MW of installed biomass power/zcogeneration, 53 MW from biomass gasifiers and 2.5 MW of solar PVs. Installed capacity for all renewables by March 2004 was more than 4,600 MW.

The International Conference for Renewable Energies is to be held in Bonn, Germany. But here is a sector dwarfed by fossil fuels, and although governments can proactively root for renewables, and some have, the options given to developing countries are qu
