Forests could end global hunger

One billion people worldwide depend on forests and trees for balanced diets and sustainable incomes

A new report has found that forests and forestry are essential if we are to achieve food security.

About one in nine people globally still suffer from hunger, with the majority living in Africa and Asia. According to the report, the world’s forests have great potential to improve their nutrition and ensure their livelihoods as the limits of boosting agricultural production become increasingly clear.

Forests, food and nutrition

The report, which launched in New York at a side-event of the United Nations Forum on Forests, is the most comprehensive scientific analysis to date on the relationship among forests, food and nutrition.

‘Forest foods often provide a safety net during periods of food shortages.

‘In the study, we reveal impressive examples which show how forests and trees can complement agricultural production and contribute to the income of local people, especially in the most vulnerable regions of the world.’

Released by the International Union of Forest Research Organizations (IUFRO), the world’s largest network of forest scientists, the report also underlines the need for the most vulnerable groups of society to have secure access to forest foods.

Benefits to nutrition

Tree foods are often rich in vitamins, proteins, and other nutrients and are associated with more diverse diets. For example, the iron content of dried seeds of the African locust bean and raw cashew nut are comparable with, or even higher than, that of chicken meat.

Wild meat, fish, and insects are also important forest food sources. Insects are an especially cheap, abundant source of protein, fat, vitamins and minerals. Particularly in south-east Asia, many forests and agroforests (tree-based farms) are managed by local communities specifically to enhance edible insect supply.

Ecological services

Forests are also essential for firewood and charcoal. In developing countries, 2.4 billion households use these renewable biofuels for cooking and heating. In India and Nepal, for example, even better-off rural households depend on wood fuels.

Trees offer a multitude of ecological services. For instance, they support bees and other pollinators, which are essential for crop production including on farmland. They also provide animal fodder that enables communities to produce meat and milk, and protect streams and watersheds as habitat for fish.

Helping the poor to make a living

According to the report, close to one in six people directly depend on forests for their food and income. In the Sahel region, for example, trees contribute 80% on average to household incomes, especially through shea nut production. Evidence also shows that, worldwide, the lower the level of prosperity, the higher the share of forests in household incomes.

The report documents efforts currently underway in Africa and elsewhere to develop new tree commodities to supply the poor with sustainable incomes.

For example, poor producers in Tanzania are engaged in a global effort to produce the seeds of the Allanblackia crop, which yield an edible oil with potential for the global food market.

A private-public partnership known as Novella Africa is developing a sustainable Allanblackia oil business that they believe could be worth hundreds of millions of dollars annually for local farmers.

‘What keeps people hungry is often not the lack of food, but the lack of access to that food and control over its production. We need to recognize claims over food sovereignty which give local people greater control over their food.

‘Improved tenure rights and stronger rights for women who are becoming more and more responsible for food production from agricultural and forest lands are key to ensure the success of sustainable poverty reduction efforts.’

Forests and food security

More than 60 renowned scientists from around the world collaborated on the peer-reviewed publication Forests, Trees and Landscapes for Food Security and Nutrition. A Global Assessment Report, which was coordinated by IUFRO on behalf of the Collaborative Partnership on Forests (CPF).

‘This report reminds us of the vital role of forests in building food security. It makes a convincing case for multi-functional and integrated landscape approaches and calls for community level engagement to re-imagine forestry and agriculture systems.’

Thomas Gass, Assistant Secretary-General for Policy of the UN Department of Economic and Social Affairs

Linking forests and farming

Although forests are not a panacea for global hunger, the report emphasises that they play a vital role in complementing crops produced on farms. This is especially important when the staple food supply is impaired by droughts, volatile prices, armed conflicts, or other crises.

‘Large-scale crop production is highly vulnerable to extreme weather events, which may occur more frequently under climate change. Science shows that tree-based farming can adapt far better to such calamities.

‘We know that forests already play a key role in mitigating the effects of climate change. This report makes it very clear that they also play a key role in alleviating hunger and improving nutrition.’

Christoph Wildburger, coordinator of IUFRO’s Global Forest Expert Panels (GFEP) initiative

This forest-farm link also means that the loss and degradation of forests exacerbate the problem of food insecurity. The report points out that the expansion of agricultural land accounts for 73% of forest loss worldwide.

The study comes in the lead up to the United Nations’ finalisation of the Sustainable Development Goals, designed to address, among other global challenges, poverty and hunger. The report also provides useful insight into how the UN can respond to the ‘Zero Hunger Challenge’, which aims to eliminate global hunger by 2025.
