How can we boost agricultural output and improve rural livelihoods in the developing world (especially sub-Saharan Africa) without attendant land/forest degradation and resultant biodiversity loss?

Sub-Saharan Africa is the poorest region of the world and experiencing high rates of land degradation, desertification, forest degradation and loss. The ecology-welfare link in this part of the world is very strong and most people live outside formal institutions and markets. Declining crop yields have meant agricultural expansion and in places like the Eastern Afromontane Hotspot this means large potential for the loss of endemic species. Livelihoods here are also closely tied to annual rainfall patterns and any near term changes in these as a result of climate change may also rationalize further agricultural expansion (e.g. to areas with more stable rainfall, or as an insurance mechanism to ensure a certain level of output). Here we have a nexus of severe poverty, high biodiversity, poor agricultural productivity, climate vulnerability and potential loss of carbon stored in woodland and forest ecosystems.

In terms of livelihood risks and planning challenges, is rainfall variability more significant than climate change?

Rainfall patterns typically vary in a basin. This variability presents major risks to farmers’ livelihoods and challenges to planners to create proper structures for water storage and conveyance. With climate change, the frequency of extreme events is expected to increase and make the impacts of variability more pronounced. It is therefore important to clarify the significance of rainfall variability and suggest approaches to document and deal with the challenges involved.

Most of our food is produced from the rainfed areas. Disturbing the existing system could cause great frustrations to the growers, and possible food deficiencies in the future.

Country like India very much depend on its economy in agriculture. So the rainfall amount determine the agriculture sector growth etc.

Does global warming bring more rain or less rain, and how the rainfall pattern is changed around the globe?

water is one of the most important resources affecting people’s lives. We need to know how global warming changes the pattern of the rainfall, so the policy makers and governments can plan and implement policies that can mitigate severe problems such as drought or flooding, and infrastructure to distribute water effectively.

How to save each and every drop of rain water to raise underground water level in next decade.

Shortage of drinking water has already become a serious problem in many countries particularly third world countries, African countries, Gulf countries and many south Asian countries and even Oz. There could be “water war” in the future. Efforts to save every drop of rain water so that underground water level will rise up. Unfortunately most of the rain water drain from river to sea and to oceans which is of no use for us to drink. Therefore time has come to start not thinking but to do something so that rain water can be saved by rain water harvesting in cities, making ponds, lakes, small dams, large dams etc. wherever possible. Because WATER means life and life means Worlds Animal,Trees, Environment Resources,(WATER).

How much can cloud seeding be effective to get artificial rain? What are possible consequences on soil fertility and human health?

Silver iodide is used to spray on the clouds to obtain artificial rain. Then what about chemical compounds? These compounds may get mixed up with rain drops and while raining may get mixed up in soil and water. An experiment may give water but reduces soil fertility, as read in the paper. It is also possible that the such water may be hazardous to human health. In this case how much can cloud seeding be useful?
