<div type="abstract" xml:lang="en">
<p>There is an ongoing debate on what constitutes sustainable intensification of agriculture (
<italic>SIA</italic>
). In this paper, we propose that a paradigm for sustainable intensification can be defined and translated into an operational framework for agricultural development. We argue that this paradigm must now be defined—at all scales—in the context of rapidly rising global environmental changes in the Anthropocene, while focusing on eradicating poverty and hunger and contributing to human wellbeing. The criteria and approach we propose, for a paradigm shift towards sustainable intensification of agriculture, integrates the dual and interdependent goals of using sustainable practices to meet rising human needs while contributing to resilience and sustainability of landscapes, the biosphere, and the Earth system. Both of these, in turn, are required to sustain the future viability of agriculture. This paradigm shift aims at repositioning world agriculture from its current role as the world’s single largest driver of global environmental change, to becoming a key contributor of a global transition to a sustainable world within a safe operating space on Earth.</p>

<title>Introduction</title>
<p>A global food revolution based on a new paradigm for agricultural development is urgently required. Without this shift, we are unlikely to attain the twin objectives of feeding humanity and living within boundaries of biophysical processes that define the safe operating space of a stable and resilient Earth system (Steffen et al.
<xref ref-type="bibr" rid="CR63">2015b</xref>
). Global sustainability is increasingly understood as a prerequisite to attain human development (UN GSP
<xref ref-type="bibr" rid="CR71">2012</xref>
) at all scales, from local farming communities to cities, nations, and the world (Folke et al.
<xref ref-type="bibr" rid="CR23">2005</xref>
). The reason is that we have entered a new geological epoch, the Anthropocene, where human pressures are causing rising global environmental risks and for the first time constitute the largest driver of planetary change (Steffen et al.
<xref ref-type="bibr" rid="CR60">2007</xref>
,
<xref ref-type="bibr" rid="CR63">2015b</xref>
). Agriculture is at the heart of this challenge. It is the world’s single largest driver of global environmental change (Tilman et al.
<xref ref-type="bibr" rid="CR67">2001</xref>
; Foley et al.
<xref ref-type="bibr" rid="CR21">2005</xref>
; Godfray and Garnett
<xref ref-type="bibr" rid="CR28">2014</xref>
; Kuyper and Struik
<xref ref-type="bibr" rid="CR38">2014</xref>
) and, at the same time, is most affected by these changes (IPCC
<xref ref-type="bibr" rid="CR34">2014</xref>
). Agriculture is the key to attaining the UN Sustainable Development Goals of eradicating hunger and securing food for a growing world population of 9–10 billion by 2050, which may require an increase in global food production of between 60 and 110 % (Foley et al.
<xref ref-type="bibr" rid="CR21">2005</xref>
; IAASTD
<xref ref-type="bibr" rid="CR32">2008</xref>
; Tilman et al.
<xref ref-type="bibr" rid="CR66">2011</xref>
; Pardey et al.
<xref ref-type="bibr" rid="CR44">2014</xref>
) in a world of rising global environmental risks. Agriculture is also the direct livelihood of 2.5 billion smallholder farmers (FAO
<xref ref-type="bibr" rid="CR15">2013a</xref>
), and the resilience of these livelihoods to rising shocks and stresses is currently gravely under-addressed (FAO
<xref ref-type="bibr" rid="CR16">2013b</xref>
).</p>
<p>Together, these insights provide a strong scientific justification for a shift from our current paradigm for agriculture of focusing on productivity first and sustainability as a question of reducing environmental impacts, to a paradigm where sustainability constitutes the core strategy for agricultural development. The planetary boundary definition of a safe operating space for a stable and resilient Earth system provides an operational framework for defining what constitutes sustainable agriculture. It has been proposed (Keating et al.
<xref ref-type="bibr" rid="CR37">2014</xref>
) that the “safe operating space” exploration of food security (Beddington et al.
<xref ref-type="bibr" rid="CR3">2012</xref>
), based on these principles (Rockström et al.
<xref ref-type="bibr" rid="CR55">2009</xref>
), analytically frames the problem and describes the interconnected forces of population growth, consumption growth, environmental change, and food security.</p>
<p>The definition of a biophysical safe operating space of the Earth system, within which it has a high likelihood of remaining in a stable inter-glacial state, emerges from the advancements in Earth system science over the past decades, providing evidence of interactions, feedbacks, and thresholds among environmental processes that regulate the Earth system (Lenton et al.
<xref ref-type="bibr" rid="CR41">2008</xref>
), and the conclusion that humanity has entered a new geological Epoch, the Anthropocene (Waters et al.
<xref ref-type="bibr" rid="CR73">2016</xref>
), where the world constitutes the largest driver of change on Earth.</p>
<p>Therefore, in the Anthropocene, humanity faces the imperative question of how to transform agriculture that feeds the world, contributes to eradicate poverty, and contributes to a stable planet. Given the decisive role of world agriculture on human development and on Earth system processes, we argue in this paper that sustainable agriculture is the only strategy that can deliver productivity enhancements to meet rising food needs and enable an Earth system operating within planetary boundaries.</p>
<p>There is a well-documented debate (Garnett and Godfray
<xref ref-type="bibr" rid="CR25">2012</xref>
; Kuyper and Struik
<xref ref-type="bibr" rid="CR38">2014</xref>
) on what constitutes sustainable intensification of agriculture (
<italic>SIA</italic>
) (Garnett et al.
<xref ref-type="bibr" rid="CR26">2013</xref>
; Godfray and Garnett
<xref ref-type="bibr" rid="CR28">2014</xref>
; Struik et al.
<xref ref-type="bibr" rid="CR64">2014</xref>
), its evolution (Kuyper and Struik
<xref ref-type="bibr" rid="CR38">2014</xref>
; Struik et al.
<xref ref-type="bibr" rid="CR64">2014</xref>
), and its role in addressing global food security (van Noordwijk and Brussaard
<xref ref-type="bibr" rid="CR72">2014</xref>
).</p>
<p>Here,
<italic>SIA</italic>
is largely on how to enhance agricultural productivity while reducing its environmental impacts (Conway
<xref ref-type="bibr" rid="CR9">1997</xref>
; Godfray and Garnett
<xref ref-type="bibr" rid="CR28">2014</xref>
; Kuyper and Struik
<xref ref-type="bibr" rid="CR38">2014</xref>
). The task is how to produce more food with fewer resources. Sustainable intensification, in this context, seeks to increase agricultural output while keeping the ecological footprint as small as possible. This is, in no doubt, a useful and relatively important feature of sustainable agriculture, particularly as mainstream agriculture development still concentrates on productivity and places limited focus on sustainability. It remains focused though on avenues for resource efficiency, e.g., based on assumptions that efficiency in water and fertilizer use represents the avenues towards sustainable agriculture. Particularly in agricultural development in poverty-stricken regions, this “productivity first” paradigm, while potentially reducing environmental impacts, prevails.</p>
<p>There is an urgent need to shift this around and instead use sustainable principles as the entry point for generating productivity enhancements, which fundamentally requires real progress in increasing agricultural output by capitalizing on ecological processes in agro-ecosystems (Struik et al.
<xref ref-type="bibr" rid="CR64">2014</xref>
; van Noordwijk and Brussaard
<xref ref-type="bibr" rid="CR72">2014</xref>
). This can be achieved by managing farmers’ fields, watersheds, landscapes, and regions using strategies and practices that maintain biophysical stability and uphold critical feedbacks, such as moisture feedback from forests generating downwind rainfall (Gordon et al.
<xref ref-type="bibr" rid="CR30">2008</xref>
) and carbon sinks in soils and biomass (Le Quéré et al.
<xref ref-type="bibr" rid="CR42">2015</xref>
).</p>
<p>Incorporating ecological landscape approaches that make smart use of the natural functionalities that ecosystems offer is now an important part of the development of sustainable intensification of agriculture. The aim is to design multi-functional agro-ecosystems that are both sustained
<italic>by</italic>
nature and sustainable
<italic>in</italic>
their nature (Tittonell
<xref ref-type="bibr" rid="CR68">2014</xref>
).</p>
<p>In this paper, we propose that a new paradigm for
<italic>SIA</italic>
can be quantitatively defined from scientific advancements of the Anthropocene and biosphere resilience and translated into an operational framework for agricultural development. At its foundation, the new paradigm recognizes that the biophysical boundaries of Planet Earth impose a hierarchy of criteria on the definition of sustainability: sustainability is not a relative concept or an act of balancing competing claims; it sets absolute biophysical limits. It is only within such biophysically defined boundaries, such as operating within a 1.5 °C global carbon budget or within environmental water flows for river basins, which—as far as our current scientific knowledge shows—we stand a high probability of avoiding irreversible shifts in environmental conditions. The planetary boundary analysis sets the boundary for a stable climate system at 350 ppm of CO
<sub>2</sub>
(uncertainty range of 350–450 ppm) or maximum 1 W/m
<sup>2</sup>
of climate forcing (uncertainty range 1–1.5 W/m
<sup>2</sup>
), which translates to an average global temperature rise of approximately 1.5 °C (Rogelj et al.
<xref ref-type="bibr" rid="CR57">2015</xref>
; Steffen et al.
<xref ref-type="bibr" rid="CR62">2015a</xref>
). As has been suggested, only by defining development within such technically defined criteria or boundaries, social and economic trade-offs can be assessed (Fischer et al.
<xref ref-type="bibr" rid="CR19">2007</xref>
). Recent works (Jackson et al.
<xref ref-type="bibr" rid="CR35">2012</xref>
; Tittonell
<xref ref-type="bibr" rid="CR68">2014</xref>
; van Noordwijk and Brussaard
<xref ref-type="bibr" rid="CR72">2014</xref>
) signal mechanisms and demonstrate principles that suggest that such a transformative approach to
<italic>SIA</italic>
is possible and this paper presents examples of ways forward.</p>
<p>We suggest adding a new dimension to sustainable agricultural development, namely managing natural capital for long-term productivity and social–ecological resilience at field, watershed, and regional scales, in agricultural systems that operate within planetary boundaries to safeguard Earth system.</p>
<p>Our approach builds on existing research and the current evolution of the frameworks for
<italic>SIA</italic>
giving further emphasis to land-use planning and management of natural capital in both agro-ecosystems and natural ecosystems across scales. A resilience (capacity to deal with shocks and stress) and Earth system (in the Anthropocene) focus is key to deal with a rising frequency of multiple shocks triggered by regional and global changes unprecedented in human history.</p>
<p>Furthermore, such a comprehensive sustainability paradigm, which not only minimizes environmental impacts but also uses sustainability as the strategy to raise productivity, improve livelihoods, and build resilience and Earth system stability, must meet the dramatic rise in food requirements from a world population of nearly 10 billion by 2050, which most likely will reach 11 billion by the end of the century (Gerland et al.
<xref ref-type="bibr" rid="CR27">2014</xref>
). Together, these challenges—the social dimension of meeting rapidly rising food requirements and the ecological dimension of building agricultural resilience and Earth system stability—form a social–ecological framework for sustainable intensification of world agriculture (Jackson et al.
<xref ref-type="bibr" rid="CR35">2012</xref>
).</p>
<p>The criteria and approach we propose, for a paradigm shift towards
<italic>SIA</italic>
, integrates the dual and interdependent goals of using sustainable practices to meet rising human needs while contributing to resilience and sustainability across scales. Both of these, in turn, are required to sustain the future viability of agriculture. This paradigm shift aims at repositioning world agriculture from its current role as the world’s single largest driver of global environmental change, to becoming a critical agent of a world transition to global sustainability within the biophysical safe operating space on Earth.</p>
<p>A transformation to sustainable intensification is thus justified both by necessity (to safeguard global sustainability, a precondition for long-term agricultural viability) and by opportunity (to use sustainable practices as a vehicle for a second green revolution).</p>

<title>Background</title>
<sec id="Sec2">
<title>The necessity of a transformation of sustainable intensification of agriculture</title>
<p>The case for intensification has been well articulated in the literature, both from a perspective of increased production, through high-yielding crops, increased irrigation, mechanization, and the role of chemicals that increase production levels (World Bank
<xref ref-type="bibr" rid="CR76">2007</xref>
), and from a conservation perspective, in terms of the millions of hectares of forests which otherwise would be converted into farm land, unquantifiable amount of ecosystem services saved, and of some 590 billion tons of CO
<sub>2</sub>
prevented from being released into the atmosphere (Burney et al.
<xref ref-type="bibr" rid="CR5">2010</xref>
). We however underline the fact that much of such intensification has taken place with production increases being the primary, if not the sole, objective, whose negative consequences were understood after-the-fact and are now well documented.</p>
<p>Convincing evidence has emerged that humanity has entered the Anthropocene, where human pressures have reached a planetary scale in terms of ecosystem and resource constraints and rising risks of environmental shocks and large-scale tipping points (Lenton et al.
<xref ref-type="bibr" rid="CR41">2008</xref>
; Rockström et al.
<xref ref-type="bibr" rid="CR56">2014</xref>
; Steffen et al.
<xref ref-type="bibr" rid="CR62">2015a</xref>
; Waters et al.
<xref ref-type="bibr" rid="CR73">2016</xref>
). A rapid world transformation to global sustainability is increasingly acknowledged as necessary to enable human development within a functioning and healthy environment.</p>
<p>Agriculture is a primary driver of global change and is the single largest contributor to the rising environmental risks of the Anthropocene (Foley et al.
<xref ref-type="bibr" rid="CR22">2011</xref>
; Steffen et al.
<xref ref-type="bibr" rid="CR61">2011</xref>
; Struik et al.
<xref ref-type="bibr" rid="CR64">2014</xref>
). It is also in the Anthropocene that the challenge of feeding humanity needs to be resolved. The number of hungry people in the world remains at approximately 900 million (FAO, Ifad and WFP.
<xref ref-type="bibr" rid="CR18">2013</xref>
). At the same time, with rising living standards of the growing middle class, diets are shifting towards more livestock products that require more land and water resources than vegetarian sources of nutrition. In order to feed the world in 2050, global food production may have to increase by 60–110 % (Pretty
<xref ref-type="bibr" rid="CR47">2008</xref>
; IAASTD
<xref ref-type="bibr" rid="CR32">2008</xref>
; Tilman et al.
<xref ref-type="bibr" rid="CR66">2011</xref>
; Ray et al.
<xref ref-type="bibr" rid="CR52">2013</xref>
; Pardey et al.
<xref ref-type="bibr" rid="CR44">2014</xref>
). The challenge is further complicated by the need not only to produce more, but also to manage the entire food supply chain much more efficiently, reducing waste which has reached unacceptable proportions (estimated at 30%) along with promoting better distribution, access, and nutrition (FAO
<xref ref-type="bibr" rid="CR12">2011a</xref>
). This requires nothing less than a planetary food revolution which, for the foreseeable future, will largely be driven by the 2.5 billion smallholders that control 500 million small farms and which provide up to 80 % of the food supply in Asia and sub-Saharan Africa (FAO
<xref ref-type="bibr" rid="CR14">2012</xref>
) while residing in some of the world’s most social–ecologically vulnerable regions.</p>
<p>Today, approximately 40 % of the world’s terrestrial surface has been transformed to agriculture (crop, fiber, biofuel, and livestock production systems) (Ramankutty et al.
<xref ref-type="bibr" rid="CR51">2008</xref>
). Appropriate land for food production, however, is a finite resource and hence further expansion could compromise development within Earth’s safe operating space (approximately 25% of anthropogenic emissions of greenhouse gases are sequestered on land, of which all occurs in terrestrial non-cultivated ecosystems). If business-as-usual prevails, the expected range of cropland expansion (123–495 Mha per annum) would overshoot the preliminary estimate of the “safe operating space” of 1640 Mha well before 2050 (UNEP
<xref ref-type="bibr" rid="CR70">2014</xref>
).</p>
<p>Sustainable intensification of agriculture, in our proposed paradigm, aims at hunger reduction through biodiversity conservation that secures ecological functions in agricultural landscapes. It will require well-informed regional and targeted solutions (Tscharntke et al.
<xref ref-type="bibr" rid="CR69">2012</xref>
) drawing upon the strengths of both land-sparing and land-sharing approaches underpinned by strategic land-use planning and allocation (Law et al.
<xref ref-type="bibr" rid="CR40">2015</xref>
) across local, regional, and basin scales. Fischer et al. (
<xref ref-type="bibr" rid="CR20">2008</xref>
) conclude that land sparing is readily compatible with optimization methods that attempt to allocate land uses in the most efficient way, while sustainable agro-ecological systems emphasize heterogeneity, resilience, and ecological interactions between farmed and unfarmed areas. Both social and biophysical factors influence which approach is feasible or appropriate in a given landscape. Our approach in this paper seeks to draw upon the strengths of each approach, although the focus of this paper is on transforming agricultural systems into sustainable agro-ecological systems. As mentioned above, however, conservation measures including protected area habitats, areas co-managed with local communities, and indigenous reserves are all potentially viable sustainable intensification strategies (Phalan et al.
<xref ref-type="bibr" rid="CR45">2011</xref>
; Garnett et al.
<xref ref-type="bibr" rid="CR26">2013</xref>
).</p>
<p>Our current agricultural inputs are also a challenge. Agriculture is the single largest user of freshwater in the world, with 70 % of the totally withdrawn water of almost 6000 km
<sup>3</sup>
 year
<sup>−1</sup>
being diverted for agriculture (Kabat
<xref ref-type="bibr" rid="CR36">2013</xref>
), which has resulted in approximately 25 % of the world’s major river basins no longer reaching the ocean (Comprehensive Assessment of Water Management in Agriculture
<xref ref-type="bibr" rid="CR8">2007</xref>
). Agriculture is the world’s largest contributor to altering the global nitrogen and phosphorus cycles (Carpenter
<xref ref-type="bibr" rid="CR6">2005</xref>
). Anthropogenic uptake of N from the atmosphere (for industrial and intentional biological fixation of N) today exceeds the natural global uptake of N for biomass growth (Galloway and Cowling
<xref ref-type="bibr" rid="CR24">2002</xref>
; Gruber and Galloway
<xref ref-type="bibr" rid="CR31">2008</xref>
) and currently at approximately 150 Tg N year
<sup>−1</sup>
the global uptake far exceeds the boundary value of 62–82 Tg N year
<sup>−1</sup>
(Steffen et al.
<xref ref-type="bibr" rid="CR62">2015a</xref>
).</p>
<p>Although the focus of this paper is on sustainability as the strategy for productive agriculture, it is recognized that a case for sustainable intensification must also tackle the challenge of improving the health and livelihoods of the 2.5 billion smallholder farmers who are the primary stewards of our natural resources. As highlighted in the Global Nutrition Report (IFPRI
<xref ref-type="bibr" rid="CR33">2015</xref>
), improving nutrition status reduces disease burdens, increases income, improves life expectancies, and provides a host of additional socioeconomic benefits to families and communities. These benefits are essential drivers of sustainable development. A key strategy is investing in food that is healthy for people and planet, where nutritional food, low in refined sugars, fats, and meat, can help combat malnourishment and obesity and reduce emissions of greenhouse gases and resource footprints (Tilman and Clark
<xref ref-type="bibr" rid="CR65">2014</xref>
; IFPRI

World agriculture must now meet social needs and fulfill sustainability criteria that enables food and all other agricultural ecosystem services (i.e., climate stabilization, flood control, support of mental health, nutrition, etc.) to be generated within a safe operating space of a stable and resilient Earth system, which in turn can be defined from Earth system science applying the planetary boundary framework (Table

<p>Recognizing the central role agriculture plays in determining and regulating Earth’s resilience, and the sustainability criteria for agriculture (outlined in Table 
<xref rid="Tab1" ref-type="table">1</xref>
), there is a strong case for adopting sustainable intensification of agriculture as the strategy to meet twin objectives for people and the planet. The “human goal,” adopted by the UN Sustainable Development Goals (SDGs) in 2015, is to eradicate hunger and poverty by 2030 (which will require >50 % increase in food production). The global sustainability goal (as defined by Table 
<xref rid="Tab1" ref-type="table">1</xref>

) and can only be translated as the UN SDGs setting out to feed humanity this within a safe operating space of a stable and resilient Earth system. Together, these integrated goals will require a doubly green revolution (Conway
<xref ref-type="bibr" rid="CR9">1997</xref>
) within ambitious and absolute targets for sustainability: in principle (1) net zero emissions of greenhouse gases, (2) very low or zero expansion of agriculture into remaining natural ecosystems, while restoring others providing vital ecosystem services, (3) zero loss of biodiversity, (4) drastic reduction in excessive use of N and P (recycling nutrient flows), and (5) major improvement in water productivity and safeguarding of environmental water flows. These will require, among others, conducive legal and institutional frameworks, incentives, rights, infrastructure, and support services that farmers will need for implementation.</p>
<p>From these social–ecological criteria emerges a clear definition of sustainable intensification: adopting practices along the entire value chain of the global food system that meet rising needs for nutritious and healthy food through practices that build social–ecological resilience and enhance natural capital within the safe operating space of the Earth system.</p>

<italic>SIA</italic>
requires safeguarding not only local (on-farm) productivity through sustainable practices, but also ecological functions across scales, from watershed, to basin, region, and Earth system scales, to avoid, e.g., loss of rainfall during future growing seasons. It furthermore requires building the capacity to deal with rising frequency and amplitude of shocks and stresses as a result of global changes (e.g., droughts and floods exacerbated by climate change; disease outbreaks promoted by globalization).</p>
<p>For example, with rising risks of water shocks at the local scale—droughts, floods, and dry spells, it is increasingly important to manage water across scales—from local farm fields to watersheds and river basins. Spatial planning strategies are required to safeguard multi-functional landscapes, with a diverse set of ecosystems that are able to dampen the effects of storm-floods and maximize sub-surface flows of water rather than erosive surface runoff. Wetlands, meandering rivers, forests, and landscape mosaics are important natural capital assets that build resilience. Moreover, watershed and river basin management is required to safeguard rainfall. In many parts of the world, a large portion of rainfall (often >50 %) is convective, originating from local scale to meso-scale vapor flows, in particular from upwind evaporating forests contributing moisture flows that generate rainfall downwind. This so-called moisture feedback is common to the Sahel region where moisture from the West African rainforests in the south provides rainfall on the semi-arid savannah in the north. These examples demonstrate the importance of managing water at the watershed and regional scale in order to secure rainfall and therefore future food production at the local scale. This landscape approach needs to be nurtured and facilitated by a social–ecological framework for policy design and on-ground implementation (IAASTD

The sources of sustainable practices range across all areas of agricultural development, in soil tillage systems, water resource management, crop and nutrient management, livestock practices, integrated landscape management, pest management, and management of ecosystem services are already evident and what is required is a scaling up.

<p>The Comprehensive Assessment of Water Management in Agriculture (
<xref ref-type="bibr" rid="CR8">2007</xref>
) showed that there is a large untapped potential in upgrading rainfed agriculture in savannah regions (covering 40 % of the Earth’s surface) by enhancing rainwater harvesting. As an example, in semi-arid areas of Niger and Burkina Faso, small-scale farmers use planting pits to harvest rain water and rehabilitate degraded land for the cultivation of millet and sorghum. In Burkina Faso alone, these practices have helped rehabilitate up to 300 000 hectares of land and produce an additional 80 000 tons of food per year (Reij et al.
<xref ref-type="bibr" rid="CR53">2009</xref>
). In addition, in southern Niger, farmers are innovatively regenerating and multiplying valuable trees on their lands, and this has improved about 5 million hectares while producing more than 500 000 additional tons of food per year resulting in improved food security for about 3 million people. Other ecosystem benefits registered included reduced wind speed and evaporation (Reij et al.

An ICRISAT-led activity is promoting integrated watershed management in the Yewol watershed in the Amhara Regional State, Ethiopia. By strengthening local capacity, facilitating collective action, using research to identify niches for integration of technologies at farm and landscape scales, and introducing system compatible technologies, the project has led to improved productivity, crop diversification, improved downstream water availability, and strengthened livelihoods for an estimated 15 000 beneficiaries (Evaluation of WLE

<title>Challenges for science</title>
<p>Adopting a livelihood-centered paradigm for sustainable intensification within planetary boundaries is a major challenge for research and development that will require new approaches to how research for development is formulated, managed, and executed.</p>
<p>Pursuing
<italic>SIA</italic>
will entail approaches that integrate social and natural sciences, in solution-oriented knowledge generation that couples academic and practical knowledge through co-design and co-development of research. The implementation of
<italic>SIA</italic>
will require an understanding of the political economy in which food is traded and prices are determined and the business economy along the value chain from field to consumer. A major reason why farmers persist in growing water-intensive crops even in water-scarce regions is that State support for prices and procurement is limited to such crops and is not available for more ecologically appropriate crops such as pulses and millets. The result has been the emergence, for example of the “Punjab Water Syndrome,” where falling water tables combine dangerously with waterlogging in other parts of the state in India (Kulkarni and Shah
<xref ref-type="bibr" rid="CR39">2013</xref>
). However, the aforementioned could be addressed through innovative incentive-based approaches that result in distinct behavior changes (see Box
<xref rid="Tab3" ref-type="table">2</xref>
).</p>
<p>A lasting paradigm shift will require the ability to place research into policy and enable large-scale change. Influencing policy requires an understanding of the power dynamics and political systems that both enable and undermine the shift to
<italic>SIA</italic>
, associated improvements in livelihoods, and protection of the environment. Institutional trust will need to be built among the many stakeholders in the food system, all of whom will be required to make compromises. While
<italic>SIA</italic>
needs to be central to the way we produce food in the future, it also needs to be integrated within a nexus of strategies aimed at achieving food system sustainability, in the broadest sense of the phrase (Godfray and Garnett
<xref ref-type="bibr" rid="CR28">2014</xref>
).</p>
</sec>
<sec id="Sec7">
<title>Grand experiments for transformation, co-design, and learning</title>
<p>It should be recognized that
<italic>SIA</italic>
is a new, evolving concept, and its meaning and objectives subject to debate and contest. Sustainable intensification is only part of what is needed to improve food system viability and sustainability and is not synonymous with food security. Both sustainability and food security have multiple social, ethical, and environmental dimensions. Achieving a sustainable, health-enhancing food system for all will require more than just changes in agricultural production, essential though these are. Equally radical agendas will need to be pursued to reduce resource-intensive consumption and waste and to improve governance, e.g., on trade, incentives and equity. Much hope has been generated by India’s 12th Five Year Plan, which adopts a paradigm shift in water resource management, exactly along the lines proposed in this paper (Shah
<xref ref-type="bibr" rid="CR59">2013</xref>
). A promising development is the emphasis in the strategic plan of the CGIAR until 2030 (CGIAR
<xref ref-type="bibr" rid="CR7">2015</xref>
), which places reduced poverty, improved food and nutrition security for health, and improved natural resources and ecosystem services, as its three highest level system outcomes. As the CGIAR played a pivotal role in the 1st Green Revolution, this creates the potential framework for a 2nd Green Revolution based on
<italic>SIA</italic>
principles.</p>
<p>Similarly, FAO pursues a strategic transformation, which endorses an ecosystem approach in agricultural management for sustainable crop production intensification, provides associated policy advice, and envisages a vision of sustainable food and agriculture that merges access by all to nutritious food with ecosystem-focused natural resources management (FAO
<xref ref-type="bibr" rid="CR13">2011b</xref>
,
<xref ref-type="bibr" rid="CR17">2014</xref>
).</p>
<p>The shift outlined in this article demands a new framework for research and development. Major productivity enhancements are required, and the strategy is through sustainable intensification of agricultural practices for livelihoods that build farm, community, and biosphere resilience. New research and development is required to advance fresh integrated whole-of-systems approaches for sustainable intensification, which can inspire and influence all domains involved in agricultural development, from economics to biotechnology.</p>
<p>We believe one strategy forward is the investment in spatially concentrated major “grand experiments” where knowledge from different domains, ranging from irrigated to rainfed agriculture, ecology and agronomy, equity to business development, work together to pilot sustainable intensification at scale (e.g., in a region or basin), to pool experience, explore synergies and trade-offs, testing the hypothesis that sustainable intensification can deliver food, livelihoods, and resilience, while contributing to development within Earth’s safe operating space. These would be large R&D investments. They would deviate from the normal business-as-usual approaches of discipline by discipline, sector-by-sector, scale-by-scale approaches to agricultural development. They would be system-integrating and innovative ventures, and thus challenging but, as argued in this paper, necessary. Evidence strongly suggests that sustainable transformations of agricultural systems are direly and urgently required to meet World and Earth needs.</p>
