Biofuels – Original Thinking • Excluding the land-use change, the first generation biofuels were projected to have a GHG saving between 10 and 90%. • Biofuels have been proposed to minimise the GHG reductions and a potential way to achieve 2 °C target (Mitigation) • To restrict global temperature increase to 2 °C – By 2030, biofuels to provide 9% of total transport fuel demand (126 EJ): current level 2.7% of the world's fuels for road transport (World Energy Outlook 2009; IEA 2009)

• Area under Biofuel crops - 1% of arable land, will occupy 2.5 – 3.8% by 2030 (IEA 2006) – By 2050 , 50% reduction in CO2 emissions, biofuels to provide 26% of total transport fuel (Blue map Scenario of Energy Technology Perspective, IEA 2008)

• Will need ~7.5 – 11.4% arable land? Can this be achieved with current biofuel crops without impacting climate change? 4 With LUC whether the Biofuel crops still be environmentally friendly? 375 – 750 Mha


Biofuel Production Trend

Driven by mandates and subsidies – independence in fossil fuel imports and reducing the climate foot prints Use of traditional first generation crops (food) Big Debate in EU on capping the use of food based biofuels Many countries faltering in implementing mandates and targets Need clear-cut policies and sustainable systems

Debate : Land-use Change (LUC) & Carbon Debt

o Long carbon paybacks if forests are converted to produce biofuels with traditional first generation biofuel crops

LUC & Carbon Debt : Brazil 2020

Lapola D M et al. PNAS 2010;107:3388-3393

Projected Demand 8.0 Billion gallons (E20-25; B5)

Direct, indirect, and total LUC areas (A), carbon debt (B), and time to repay debt (C) for fulfilling Brazil’s biofuel (sugarcane 8 ethanol and soybean biodiesel) production targets for 2020.


Where does this leave us? o Need for rethinking on Biofuels that addresses current concerns: a system based approach rather than crop based!! o Position Biofuels for food security and livelihood improvements beyond solution for transport mix o Refresh national policies: based on solid science o Explore alternate models which avoids LUC and have positive carbon footprints / low carbon payback years o Develop active linkages with global initiatives especially from the UN o Learn from successful examples from across the globe and adopt for India o What are aviation industries doing?

Alternate Biofuel Models : The Future Requirements

What is it? To be Driven by Local Energy Provisions for Livelihoods, Use of Marginal Land Leading to National Mandates

 “Biofuel technologies must become more efficient in terms of net lifecycle greenhouse gas (GHG) emission reductions and be socially and environmentally sustainable.  Most first-generation biofuels, with the exception of sugarcane ethanol, will likely have a limited role in the future transport fuel mix”

CFS: HLPE 2013 Recommendations o Adapt to change to global market driven dynamics o Address the land and water implications o Comprehensive food energy policy

o Promote R&D o Develop methods and guidelines for coordinated food, biofuel bioenergy policies

Science-Based Polices Are Needed to inform sustainable bioenergy landscape design.

o “The linkage between biodiversity and ecosystem services is dependent not only on the choice of bioenergy crop but also on its location relative to other habitats. o Careful design of bioenergy landscapes has the potential to enhance multiple services in food and energy crops, leading to important synergies that have not yet informed the ongoing bioenergy debate.�

Use of Multiple Species  Mixed cropping with perennials better than monoculture o Generate higher energy yields, GHG reductions, less agrichemical pollution per hectare than first generation biofuel crops such as sugar cane ethanol or soybean biodiesel. o Give higher bioenergy yields (238% greater than monoculture yields). o Carbon negative: Net CO2 sequestration (4.4 megagram hectare–1 year–1 of CO2 in soil and roots).

Where does this lead to : India ď ś Biofuels in India and how to unlock the potential

26


Biofuels in India rethinking – refresh & recharge o The Government of India approved the National Policy on Biofuels in December 2009. o 20 percent biofuel blending (both bio-diesel and bio-ethanol) by 2017

o The Planning Commission of India had set an ambitious target covering 11.2 to 13.4 million hectares of land under Jatropha cultivation (Eucalyptus alone is grown in 8 million hectares) o The biodiesel industry in India is still in infancy o Biodiesel distribution channels are virtually non-existent as most of the biofuel produced is used either by the producing companies for self-use or by certain transport companies on a trial basis Over reliance on Jatropha, low grade waste land, no forward linkages No clearcut effort to engage smallholder farmers?

27


Unlocking the potential Feedstock costs represent 50-75% of the cost of producing biofuels

 Focus on marginal land – but explore in farm options  Value Chains not exploited  Over reliance on annual crops - Often Food Crops  Monoculture (LUC & iLUC) & Jatropha  Availability (seasonal, quality, consistency)  Agroforestry : suitable option 28


Unlocking the Potential o Agroforestry options (Bring in trees in the farm without affecting the productivity of annual crops) Potential – 25.36 million hectares o Use of marginal / underutilized land (3 million ha alone as bund) o Combine with other crops for sustainable production throughout the year, based on particular agroclimatic / ecosystem conditions o Cover the whole value chain : Landscape / System Approach • • • •

R&D Challenges Selection of Appropriate varieties (Ecosystem based) Quality planting material Short rotation crops Remunerative to small farmers 29


Agroforestry : Multiple Benefits • Less demanding in terms of inputs • Reduces erosion and improve soil properties • Animal feed and/or fertilizers as co-products • More energy per unit of land from these crop

• Brings in resilience in farming for food and nutritional security • Better micro climatic conditions for the growth of agricultural crops 30


Co-Products Enhance the Energy Value of a System

Successful Biofuel Enterprises ď ś Lessons from successful Biofuel enterprises

South-South Cooperation with Brazil  Learn from the Brazilian experience with biodiesel: o Focus on Business development with social inclusion, environmental sustainability and promotion of regional development. • More than 100,000 smallholders. • Annual average household income increased twice. o Success due to Petrobras, Brazil's state-run energy giant, created its own biofuels division in 2008 - took over from the private firms running the government's biofuels production contracts with smallholder farmers. • farmers devote no more than 20% of their arable land to growing biofuel crops o Partner with Embrapa on the development of alternate feedstocks: • Agroforestry model on Pongamia, Jatropha, Macaúba Palm and others. • Agro-ecological zoning in process.

Aviation Biofuels: Integrated Seawater Energy and Agriculture System (ISEAS)


India : Way Forward • Agroforestry Policy : Aimed at increasing the tree cover to 33% – Recommendation 10: Promoting sustainable agroforestry for renewable energy

• Biofuels : Compulsory Activity under MNREGA • Follow Brazilian Model & set up a separate Company for Bioenergy • Feed stocks : Multiple and complimentary • R&D : Short rotation and survival rates at the farmer’s field • Foster Innovation in providing multiple avenues of clean energy • Links with global private partners – specifications for biofuels and processing technologies • Provide incentives / subsidy to be competitive to Crude

Alternative : Biofuels for local energy provisions and livelihoods 39
