Linking agriculture with forestry can offer food security
The latest edition of the State of the World’s Forests (SOFO) report explores the relationship between agriculture and forestry for a food-secure future.
World leaders adopted the Sustainable Development Goals (SDGs) for the next 15 years in September 2015 to take forward the global development initiative from the Millennium Development Goals.
As part of their commitment to the SDGs, countries are committed to end hunger by 2030 by ensuring sustainable food production. Making agriculture sustainable is essential for future food production in the face of climate change.
"The 2030 Agenda for Sustainable Development, as well as the Paris Agreement on climate change, recognises that we can no longer look at food security and the management of natural resources separately," said FAO Director-General José Graziano da Silva.
Food production and the role of forests
While agriculture can feed the world’s population, it is responsible for deforestation globally. The SOFO report shows how food security can be ensured by maintaining forest cover.
According to Jonah Busch, senior research fellow at the US-based non-profit Center for Global Development, “…forests contribute toward the achievement of many Sustainable Development Goals—not just climate and biodiversity, but also food security, energy, clean water and health.”
The report says that forests support sustainable agriculture by stabilising soils and climate, regulating water flow, providing shade and shelter and providing a habitat for pollinators and natural predators of agricultural pests. When integrated judiciously into agricultural landscapes, trees can increase agricultural productivity.
“Increasing crop productivity, if paired with direct forest protection measures, can increase both agricultural production and forest cover. But without direct forest protection, increasing crop productivity can put forests at greater risk by making it more profitable to clear land for crops,” Busch added.
Ensuring food security
Forests ensure the food security of millions of people worldwide, as they are important sources of food, energy and income.
The SOFO report shows that some countries have successfully increased agricultural productivity while also halting and reversing deforestation.
Deforestation was most prevalent in the temperate climatic domain until the late nineteenth century and is now greatest in the tropical climatic domain, the report says.
Temperate countries have been decimating their forests for centuries, but these days most of their primary forests are protected. The tropics, on the other hand, are losing an area of forest the size of Portugal every year.
Talking about the relationship between agriculture and deforestation, Busch cited the example of Brazil. Since 2004, the country has reduced deforestation in the Amazon by 80 per cent while increasing soy production by 65 per cent and beef production by 21 per cent.
“They did this mainly through restrictive measures—protected areas, enforcement of forest laws, moratoria on clearing—but increased agricultural productivity played a role too. Economist Bernardo Strassburg estimates that with modest continued increases in agricultural productivity, Brazil can continue increasing agricultural production for the next 25 years without cutting more forest,” Busch told Down To Earth.
Commercial agriculture accounts for about 40 per cent of deforestation in the tropics and sub-tropics, local subsistence agriculture for 33 per cent, infrastructure for 10 per cent, urban expansion for 10 per cent and mining for 7 per cent, the SOFO report adds.
Seventy-one per cent of deforestation in South American countries in 1990–2005 was driven by increased demand for pasture, 14 per cent was driven by increased demand for commercial cropland and less than 2 per cent was the result of infrastructure and urban expansion. In Southeast Asia, oil-palm plantations and production of biofuels have replaced natural forest.
Combating climate change
As forests are “multifunctional”, they can combat climate change. The report says that reducing emissions from deforestation and forest degradation, sustainable management of forests and enhancement of forest carbon stocks will be essential to fight climate change.
“Combating climate change and ensuring food security are both extremely important. When you compare the numbers, deforestation contributes more than 10 per cent of greenhouse gas emissions annually, but it only expands the world’s agricultural land by around one-tenth of a per cent a year. This means that protecting and restoring forests is critical for stopping climate change, but the big gains in improving food security will happen elsewhere,” Busch said.
|SDGS and targets that refer explicitly to agriculture and forests
End hunger, achieve food security and improved nutrition and promote sustainable agriculture.
2.1 By 2030, end hunger and ensure access by all people, in particular the poor and people in vulnerable situations, including infants, to safe, nutritious and sufficient food all year round.
2.3 By 2030, double the agricultural productivity and incomes of small-scale food producers, in particular women, indigenous peoples, family farmers, pastoralists and fishers, including through secure and equal access to land, other productive resources and inputs, knowledge, financial services, markets and opportunities for value addition and non-farm employment
2.4 By 2030, ensure sustainable food production systems and implement resilient agricultural practices that increase productivity and production, that help maintain ecosystems, that strengthen capacity for adaptation to climate change, extreme weather, drought, flooding and other disasters and that progressively improve land and soil quality.
2.a Increase investment, including through enhanced international cooperation, in rural infrastructure, agricultural research and extension services, technology development and plant and livestock gene banks in order to enhance agricultural productive capacity in developing countries, in particular least developed countries.
2.b Correct and prevent trade restrictions and distortions in world agricultural markets, including through the parallel elimination of all forms of agricultural export subsidies and all export measures with equivalent effect, in accordance with the mandate of the Doha Development Round.
2.c Adopt measures to ensure the proper functioning of food commodity markets and their derivatives and facilitate timely access to market information, including on food reserves, in order to help limit extreme food price volatility.
Ensure availability and sustainable management of water and sanitation for all.
6.6 By 2020, protect and restore water-related ecosystems, including mountains, forests, wetlands, rivers, aquifers and lakes.
Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss.
15.1 By 2020, ensure the conservation, restoration and sustainable use of terrestrial and inland freshwater ecosystems and their services, in particular forests, wetlands, mountains and drylands, in line with obligations under international agreements.
15.2 By 2020, promote the implementation of sustainable management of all types of forests, halt deforestation, restore degraded forests and substantially increase afforestation and reforestation globally.
15.b Mobilize significant resources from all sources and at all levels to finance sustainable forest management and provide adequate incentives to developing countries to advance such management, including for conservation and reforestation.
