Prevenindo a Perda Pós-Colheita: uma Iniciativa da University of Illinois R.S. Gates, Ph.D., P.E. 16 de Julho de 2012

2 AGENDA Desafios futuros da segurança alimentar
Vários “aspectos” da perda pós-colheita O Instituto ADM e suas contribuições Post-Harvest Loss is a critical challenge facing our world’s food security. In this presentation, I will first review the changing nature of our food security challenges. I will present some alternative perspectives regarding the role of Post-Harvest Loss in food security. And I am pleased to provide you with an overview of our newly established ADM Institute for Post-Harvest Loss, and its initial projects.

3 Aumento da Demanda Mundial de Alimentos Estimado em 70% até 2050 (FAO; 2009)
Mudanças na Dieta em Países em Desenvolvimento Consumo Per Capita de Alimentos FAO predicts that the world food demand will increase rapidly in the following 40 years, by 70%. The increase mostly comes from developing countries. Rice, wheat, other cereals and meat consumption, which itself utilizes grains, top the list of commodities in terms of growth in per capita consumption, which further accelerates the demand from world population growth. The net effect is an estimated 70% increase in food demand by 2050.

4 Demanda Mundial da Produção Estimada a Duplicar de 2005 a 2050 (NAS, 2011)
Researchers at the University of Minnesota predict global crop demand will double from 2005 to Economic Groups C, D & E in these graphs comprise the middle range of per-capita GDP countries. They account for more than 60% of world population. The growth of their demand for calories and protein is more than 60%.

5 Demanda de Alimento em 2030 Exigirá Cerca de 200 Milhões de Hectares a Mais (McKinsey; 2011)
McKinsey predicts that the growth of food demand requires about 200 million added hectares which is about the total harvesting area in the United States and Canada.

6 Mudanças no Valor do Produto Contam uma História Interessante (McKinsey; 2011)
McKinsey Global Institute’s Resource Revolution A century-long decline in commodity prices was enjoyed up until about 2000, with notable exceptions in the 1970s. However, this has changed in the past two decades. This rapid increase of commodity price erases the decline in the past century. Not only human beings but also livestock and energy production require commodities, but we have limited resources to realize these demans without improving efficiency even further.

7 AGENDA Desafios futuros da segurança alimentar
X Desafios futuros da segurança alimentar Vários “aspectos” da perda pós-colheita O Instituto ADM e suas contribuições Next, let’s review some viewpoints and ideas regarding post-harvest loss.

8 PPC Varia por Região (FAO; 2011)
DADOS! kg per year Perda e desperdício de alimentos per capita (kg/ano) Data, and the knowledge we can derive from it, is critical. We see that food is mostly wasted in the consumption stage in developed countries, while food is mainly lost during production to retailing stages in developing countries.

9 PPC Varia por Produto (FAO; 2011)
PHL varies by commodity even in the same area, for example, processing and packaging losses are greatest for fruits and vegetables. Post-harvest handling and storage losses are greatest in Roots & Tubers, and in Oilseeds & Pulses.

10 Perdas de Grãos no Mundo (FAO, 2011)
Cereal losses in different regions and are highly variable, with consumption losses greatest in developed countries and post-harvest losses a significant component of other regions.

11 PPC Varia com Condições de Plantio (IBRD/WB; 2011)
External factors such as growing condition affect PHL as well. Consider Africa for example: Rising moisture content may result in greater pest damage and microbial degradation, increasing post-harvest loss. Sorghum losses in arid regions are significant in shelling and threshing operations. Across all regions, market storage losses are substantial.

12 PPC Varia entre Países para a Mesma Cultura Agrícola (FAO; 2002)
Even for the same crop, such as rise, PHL varies between countries. Reducing PHL of rice in China should focus on storage, while the other Asian countries should put more emphasis on milling.

13 PPC Varia Entre Estados em um Mesmo País (ADM Institute; 2012)
Extent of rain affects loss of black grams. In Madhya Pradesh, India, harvesting and drying stages losses are impacted by rainfall.

14 Uma Perspectiva Mais Específica: Arroz no Sudeste da Ásia (IRRI; 2011)
No SE da Ásia, perdas físicas variam de 15 a 25%. Perdas de qualidade variam de 10 a 30% (perda de valor) Consumption Crop For Southeast Asia, for example, the physical losses of rice are large, and the loss in value from reduced quality spans a broad range of up to 30% of the crop.

15 Redução de PPC e Aumento de Produção Têm Grande Potencial (McKinsey; 2011)
Reducing PHL should be considered to be a response to enhancing sustainability. Here we see that reducing food waste is one of the top three innovation opportunities to enhance productivity. McKinsey suggests that reducing PHL and increasing yields in both large and small scale account for 18% of opportunities in saving resource.

16 Pouca Atenção é Dedicada à PPC e à Produção (McKinsey; 2011)
However, little attention is devoted to controlling these losses. Only 4% of the publications in 2010 were addressing these issues.

17 Por Que Reduzir a Perda Pós-Colheita? Algumas Hipóteses
Estimativas sugerem que 1/3 da produção agrícola é "desperdiçado" e não chega ao consumidor Investimento necessário para reduzir PPC pode ser modesto Avanços tecnológicos podem tornar a redução mais viável e menos dispendiosa O fornecimento de água, energia, e solo arável é limitado – Redução da PPC pode atenuar a pressão em recursos escassos This slide summarizes the conceptual case for PHL reduction. There are 4 key points in addressing PHL: waste, investment, technology, resource sustainability: 1/3 of agricultural production is wasted and never reaches the consumer. Investments to reduce PHL could be modest Advances in application of technology should enhance profitable PHL reduction Our global supplies of land, water and energy are limited – reduced PHL can reduce resource pressures.

24 Medindo perdas na pré-colheita, na plataforma da colhedora, e na debulha/limpeza
UFV UIUC UFG UFMT Usando um método padrão desenvolvido pela EMBRAPA para a medição de perdas na colheita, professores e estudantes viajaram de Jataí, Goiás a Sinop, Mato Grosso (1,034 km) para conduzir medições de campo Data will be used to determine average R$ losses due to harvest losses and how that compares to income gained from double cropping of safrinha corn in the region. Training materials to help farmers and custom harvesters better operate, calibrate and maintain their combines will also be developed. Colhedora Média CM [%] Produção estimada a 13% CM [kg/ha] Perda total [sacas/ha] Perda em % da produção a 13% CM Velocidade da colhedora [km/h] S2 11.0 4296 2.47 3.5 4.0 S6 18.0 3814 0.89 1.4 5.5 S7 16.2 3421 1.26 2.2 4.2 Measurements from soybean harvest (February 2012) and corn harvest (July 2012) completed.

25 Avaliação das perdas qualitativas e quantitativas em graneleiros e caminhões ; explorando o uso de “silo bags” (silo tubular horizontal). Como podemos aumentar a eficiência em graneleiros? Como podemos minimizar as perdas durante o transporte? Some of the key questions that have been raised to date: How to improve efficiency in graneleiros? Can silo bags be used as temporary storage? What are potential methods to minimize transport losses? Silo bags podem servir como armazenagem temporária?
