Relationship between buffalo production, the environment and new tools of environmental management related to sustainable production systems R. Barahona-Rosales, M. F. Cerón-Muñoz, J. F. Naranjo, D. M. Bolívar
Introduction – the environmental impact of animal production All anthropogenic activities have an impact – which can be positive or negative – on the environment
Animal production is not an exception: 1. Greenhouse gas emissions (GHG - climate change) 2. Nutrient excretion (nitrogen, phosphorous) 3. Land usage 4. Energy expenditure – fossil fuel
Introduction – the environmental impact of animal production Never before there has been this amount of interest on the environment: 1. Despite lack of agreement, climate change is receiving lots of attention 2. It should be expected that agricultural activities, animal production included, take active part both in mitigating as well as adapting to climate change
Climate Smart Agriculture Agriculture and food systems must improve and ensure food security, and to do so they need to adapt to climate change and natural resource pressures, and contribute to mitigating climate change. These challenges, being interconnected, have to be addressed simultaneously. Holmgren, 2009
Climate Smart agriculture Agriculture that sustainably: ◦ increases productivity ◦ increases resilience (adaptation) ◦ reduces/removes GHGs
AND
enhances achievement of national food security and development goals Holmgren, 2009
Two Goals of Our Time 1. Achieving Food Security ◦ 1 billion hungry ◦ Food production to increase 70% by 2050 ◦ Adaptation to Climate Change critical 2. Avoiding Dangerous Climate Change ◦ ”2 degree goal” requires major emission cuts ◦ Agriculture and Land use = 30% of emissions.. ◦ ..and needs to be part of the solution
Holmgren, 2009
Mechanisms available to deal with climate changeNAMAs http://www.fao.org/inaction/micca/resources/tools /en/
Available mechanisms to deal with CC- NAMAs NAMAs A set of actions independently proposed by developing countries that lead to the reduction of GHG emissions - in a measurable, reportable and verifiable way - below the level of what would result from continuing to do things in a Business As Usual (BAU) scenario
Available mechanisms to deal with CC- NAMAs NAMAs arise from the need to close the gap between the current commitments to the Protocol and projected GHG emissions In addition, the should also help balancing the responsibilities given the high emission levels that non-Annex B countries have today González et al., 2015
Available mechanisms to deal with CC- NAMAs There are no restrictions on what project can be cataloged as NAMA Very specific projects can be classified as NAMAs as well as sectoral policies or national programs
The reduction of emissions obtained through NAMAs will not be transferred to the developed countries as a way to meet their own reduction targets González et al., 2015

Briefs words on climate change
Greenhouse gas emissions accelerate despite the reduction efforts. Most of the growth in CO2 emissions is the burning of fossil fuels

How are we today in terms of climate change? 2015 MIGHT HAVE SEEN HOTTEST SUMMER IN 4,000 YEARS – JOE SUTTON, CNN
2015 SETS A NEW RECORD FOR CATEGORY 4 AND 5 HURRICANES AND TYPHOONS - BY CHRIS DOLCEPUBLISHED OCT 22 2015 07:20 PM EDT - - WEATHER.COM
Planet Earth has definitely experienced its hottest summer since detailed records have been kept, and according to scientists, it might have been the hottest in more than 4,000 years.
A record 22 hurricanes or typhoons have reached Category 4 or 5 strength in the Northern Hemisphere this year.
The meteorological summer of June-July-August in the Northern Hemisphere saw its highest globally averaged temperature since records began in 1880, ….
The record was broken on Oct. 17 when Koppu became the nineteenth storm to reach this intensity prior to slamming into the Philippines as a super typhoon. Since then, Super Typhoon Champi, Hurricane Olaf and Hurricane Patricia added to the total.
Hurricane Joaquin on Oct. 3 when it became a Category 4 for the second time. Joaquin is the only Atlantic storm to reach Category 4 status this season. (NASA)

Our role in the face of climate change? Faced with the current situation of emissions, "nonaction" is not a defensible position - we must all participate - the task can not be in the hands of some, while others observe. Actions to mitigate and adapt to climate change should be initiated as soon as possible - any delay reduces our chances of avoiding catastrophic changes
GHG emissions in animal production systems
Main sources of GHG emission and removal in managed ecosystems (IPCC, 2007)
GHG emissions in animal production systems The livestock sector is responsible for 14.5% of total global greenhouse gas – GHG – emissions (Gerber et al., 2013) Methane (CH4)
Nitrous oxide (N2O) Carbon dioxide (CO2) www.fao.org/gleam/es/
GHG emissions in Colombian animal production systems Colombia: GHG emissions (IDEAM 2010) Agriculture 38%, 2nd sector. a) Enteric fermentation 48,5% b) Soil usage 47,5%
Global production, absolute GHG emissions and emission intensities for milk and beef
Opio et al., 2013
Animal agricultural productivity Agricultural productivity:
Worldwide – Increase, associated with improved animal feeding and breeding technologies Crops – Irrigation, fertilization, genetic improvement = Enormous increase Poultry, swine, specialized dairy = Enormous increase Beef = There is room for improvement
Global production, emissions and emission intensity for buffalo milk and meat
Opio et al., 2013
Relative contribution of different processes to GHG emission profile of buffalo milk
Opio et al., 2013
Relative contribution of different processes to GHG emission profile of buffalo meat
Opio et al., 2013
Key areas of intervention? Enteric methane emissions Manure nitrous oxide emissions
Promissing strategies to reduce enteric emissions? Among the many possibilities, these should receive a great deal of attention: 1. Forage nutritional quality, focused on reducing fiber content in the diet while ensuring adequate protein supply 2. Ensuring adequate forage availability throughout the whole year
The key should be on the sustainable intensification of animal production systems

Promising strategies to reduce manure N2O emissions? At a global scale, human activity has increased the flux of N two-fold, particularly driven by large scale fertiliser manufacturing Of the total N applied to agricultural land worldwide only 5–15% is eventually transformed into human food (Erisman et al., 2012)

Strategies to improve the efficiency of use of N • Improve N management at the farm level - replacement rate, excreta management and housing systems, mixed production systems • Improving efficiency of N use in animals - feeding, genetics • Use of excreta as fertilizers • Anaerobic digestion of excreta – Increase use of methane as fuel • Production clusters - integration, close cycles Oenema, 2006

Final thoughts Although significant, GHG emission from buffalo production systems are susceptible to reduction There are funding opportunities to allow investment towards “low carbon” buffalo production systems, benefiting both the producers and the environment
