NITI Aayog in its recently report has recommended that Ministry of Agriculture to take up mission on shifting cultivation to ensure inter-ministerial convergence between different ministries. The report was titled “Mission on Shifting Cultivation: Towards a Transformational Approach”.
Key Highlights of report
Central, State government departments of forests and environment, agriculture and allied departments have divergent approaches towards shifting cultivation. This creates confusion among grass-roots level workers and jhum farmer.
It calls for policy coherence and recognising land for shifting cultivation as agricultural land where farmers practise agro-forestry for production of food rather than as forestland. It also suggests that shifting cultivation fallows must be legally perceived and categorised as ‘regenerating fallows’ and credit facilities be extended to those who practise shifting cultivation.
It also addresses issue of food and nutritional security of communities involved in jhum cultivation during transition and transformation by broadening public distribution system (PDS) to ensure widespread access to cereals and other basic food items. It also noted that between 2000 and 2010, land under shifting cultivation dropped by 70 %.
It is traditional agricultural practice that involves clearing vegetative forest cover on land and slopes of hills, drying and burning it before onset of monsoon and cropping on it thereafter. After harvest, this land is left fallow and vegetative regeneration is allowed on it till the plot becomes reusable for same purpose in cycle.
In north east India, it is called as jhum cultivation. People involved in such cultivation are called Jhumia. Shifting cultivation is considered as important mainstay of food production for considerable population in northeast India in states like Arunachal Pradesh, Nagaland, Mizoram, Meghalaya, Tripura and Manipur.
Shifting cultivation causes in long term causes problem of land degradation and threat to ecology of the region at large. Burning of forests provide temporary nutrients like potash to soil. Burning of forests results in emissions of greenhouse gases (GHGs) such as CO2, NO2. It also increases surface run off of rainwater leading to soil erosion.
The International Day for Preservation of Ozone Layer (or World Ozone Day) is observed every year on September 16 for the preservation of the Ozone Layer. This year, the theme for the Day is ‘Keep Cool and Carry On: The Montreal Protocol’. The day was designated by United Nations General Assembly (UNGA) on December 19, 1994. Its observance commemorates the date in 1987 on which Montreal Protocol was signed on substances that deplete the ozone layer. It also is intended to spread awareness of the depletion of the Ozone Layer and search for solutions to preserve it.
The Ozone layer is fragile shield of gas which protects Earth from harmful ultraviolet (UV) radiation of Sun and thus helping preserve life on the planet. It contains high concentrations of ozone (O3) in relation to other parts of the atmosphere. Stratospheric Ozone is not harmful, but its presence on land it is harmful. Substances like Chlorofluorocarbons, halons, Carbontetrachloride are responsible for ozone layer depletion.
It is an international treaty designed to protect ozone layer by phasing out production of numerous Ozone Depleting Substances (ODSs) that are responsible for ozone depletion. It was agreed on 26 August 1987 in Montreal, Canada and entered into force on 26 August 1989. It was followed by a first meeting in Helsinki, May 1989. Under it production and consumption of key ODSs like chlorofluorocarbon (CFCs), Methyl Chloroform, CTC halons and Methyl Bromide have been phased-out globally. It is legally binding on member countries. has been ratified by 197 parties making it universally ratified protocol in UN history. It is also highly successful international arrangement, as it has phased-out more than 95% of the ODS so far as per its main mandate in less than 30 years of its existence. It has helped in recovering the ozone hole in Antarctica.
Vienna Convention for Protection of the Ozone Layer
It is multilateral environmental agreement agreed upon at the 1985 Vienna Conference and entered into force in 1988. It is one of the most successful treaties of all time in terms of universality. It has been ratified by 197 states (all UN members as well as the Niue, Holy See and the Cook Islands) as well as European Union. It acted as framework for international efforts to protect fragile ozone layer. These are laid out in accompanying Montreal Protocol. However, it does not include legally binding reduction goals for the use of CFCs, the main chemical agents causing ozone depletion.
