The new chief of the Environmental Protection Agency says he does not believe that carbon dioxide is a primary contributor to global warming.

Question raised in Rajya Sabha on Impact of Erratic Climate on Agricultural Production, 10/03/2017. There has been a significant fluctuation in production (as compared to trend) in important foodgrain crops grown in the country during last 10 years (between 2005-06 and 2014-15) due to erratic climatic behaviour (rainfall/droughts).

Question raised in Rajya Sabha on Adverse Effect of Chemical Fertilizers on Climate, 10/03/2017. Scientific studies have revealed that there is no harmful effect of chemical fertilisers with balanced and judicious use, rather have beneficial effect as it encourages soil carbon sequestration.

Crop management practices have a significant impact on greenhouse gas (GHG) emission rates, where methane (CH4) and nitrous oxide (N2O) emissions from rice paddy fields are in trade-off association. A field study for two consecutive years (2013 and 2014) was conducted to continuously measure CH4 and N2O emissions from rice paddies under various agricultural management schedules like water regimes (irrigated and rainfed), transplanting dates and nutritional amendments (synthetic fertilizer with N as ammonium sulphate, P and K according to recommended dose, and vermicompost).

Despite the spectacular success of the green revolution and achieving self-sufficiency in food production, there are increasing concerns on sustaining the pace of agricultural growth to feed the large population of our country. Lack of yield breakthroughs, deteriorating soil health, groundwater depletion, declining size of operational holdings and labour shortage are some of the prime reasons for slow growth of agriculture.

In Ethiopia, smallholder farmers’ commercialization and integration into the market has been one of the policy directions to ensure households’ progress out of poverty and maintain the sustainable development trajectory. A lot of progress has been made in this endeavor over the past couple of decades.

This study assessed intermediate results of an investment intended to support climate change adaptation and resilience-building among farmers’ cooperatives in Rwanda. The assessment was based on a purposive sampling survey of farmers’ perspectives conducted in sites in 10 programme intervention districts of the country’s 30 districts.

The impacts of climate change are felt by most critical systems, such as infrastructure, ecological systems, and power-plants. However, contemporary Earth System Models (ESM) are run at spatial resolutions too coarse for assessing effects this localized. Local scale projections can be obtained using statistical downscaling, a technique which uses historical climate observations to learn a low-resolution to high-resolution mapping. Depending on statistical modeling choices, downscaled projections have been shown to vary significantly terms of accuracy and reliability.

Question raised in Rajya Sabha on Uncertainties in Weather Patterns, 09/03/2017. Monsoon rainfall over India varies on different spatial and temporal scales.

Question raised in Lok Sabha on Impact of Climate Change on Water Resources, 09/03/2017. The average annual water availability of any region or country is largely dependent upon hydro-meteorological, topographical, geological etc. factors and is constant.
