Abstract Spatiotemporally consistent data on global cropland extent is a key to tracking progress toward hunger eradication and sustainable food production1,2. Here, we present an analysis of global cropland area and change for the first two decades of the 21st century derived from satellite data time-series. We estimate 2019 cropland area to be 1,244 Mha with a corresponding total annual net primary production (NPP) of 5.5 Pg C yr-1. From 2003 to 2019, cropland area increased by 9% and crop NPP by 25%, primarily due to agricultural expansion in Africa and South America. Global cropland expansion accelerated over the past two decades, with a near doubling of the annual expansion rate, most notably in Africa. Half of the new cropland area (49%) replaced natural vegetation and tree cover, indicating a conflict with the sustainability goal of protecting terrestrial ecosystems. From 2003 to 2019 global population growth outpaced cropland area expansion, and per capita cropland area decreased by 10%. However, the per capita annual crop NPP increased by 3.5% as a result of intensified agricultural land use. The presented global high-resolution cropland map time-series supports monitoring of sustainable food production at the local, national, and international levels.

AbstractSpatiotemporally consistent data on global cropland extent is essential for tracking progress towards sustainable food production. In the present study, we present an analysis of global cropland area change for the first two decades of the twenty-first century derived from satellite data time-series. We estimate that, in 2019, the cropland area was 1,244 Mha with a corresponding total annual net primary production (NPP) of 5.5 Pg C year−1. From 2003 to 2019, cropland area increased by 9% and cropland NPP by 25%, primarily due to agricultural expansion in Africa and South America. Global cropland expansion accelerated over the past two decades, with a near doubling of the annual expansion rate, most notably in Africa. Half of the new cropland area (49%) replaced natural vegetation and tree cover, indicating a conflict with the sustainability goal of protecting terrestrial ecosystems. From 2003 to 2019, global per-capita cropland area decreased by 10% due to population growth. However, the per-capita annual cropland NPP increased by 3.5% as a result of intensified agricultural land use. The presented global, high-resolution, cropland map time-series supports monitoring of natural land appropriation at the local, national and international levels.

The World

The world is facing major problems with regard to food production. Agricultural land suffers from various conditions which make it less efficient for crop production while the rapid population growth, especially in developing countries, raises concern for sustainable food production. The Green Revolution has failed to secure sustainable food production and it is hoped that biotechnology will facilitate the transition to more sustainable agriculture. Excellent progress has been made with both Cell Biology (tissue culture) and Molecular Biology (genetic engineering).

Current food production and consumption trends are inconsistent with the Convention on Biological Diversity’s 2050 vision of living in harmony with nature. Here, we examine how, and under what conditions, the post-2020 biodiversity framework can support transformative change in food systems. Our analysis of actions proposed in four science-policy fora reveals that subsidy reform, valuation, food waste reduction, sustainability standards, life cycle assessments, sustainable diets, mainstreaming biodiversity, and strengthening governance can support more sustainable food production and consumption. By considering barriers and opportunities of implementing these actions in Peru and the United Kingdom, we derive potential targets and indicators for the post-2020 biodiversity framework. For targets to support transformation, genuine political commitment, accountability and compliance, and wider enabling conditions and actions by diverse agents are needed to shift food systems onto a sustainable path.

Single Exception

Sustainable food production in developing countries is challenging, as it requires balancing scalability with respect for local culture and traditions. Bolivia represents a particularly interesting example; with over 36 recognized indigenous groups encompassing over 70% of the country’s population in a relatively small territory, Bolivia is considered one of the most diverse countries in the world (Ferreira et al., 2019). Agriculture in Bolivia employs over 5% of the country’s population and represents over 14% of its GDP. Yet, the introduction of new agribusiness approaches has often been met with resistance by the local communities. For example, the use of transgenic seeds in Bolivia is forbidden by law, with a single exception in soybean production (Avila and Izquierdo, 2006). As result, Bolivia is at a disadvantage in relation to its neighbors in agricultural production. In addition, high costs of transport and export of produce due to the landlocked nature of the country, compounded by logistic difficulties of exporting through a third country, highlight the need of policies that facilitate a larger and more efficient food production.

Direct Distribution

There is growing interest in local organic food nowadays, prompted by concerns about health, care of the environment and excessive transportation and packaging of produce. But conventional marketing systems are not really able to cater for such demands, because they operate on too large a scale. In recent years a solution to the problem has appeared: direct links between growers and consumers, within the same local area. Some of these are growing rapidly, opening up exciting possibilities for the development of sustainable food production and marketing, and for building new links between cities and the countryside.
