Understanding the dynamics of food production is critical to improving food security. This is particularly important in regions that rely on subsistence agriculture with little adaptive capacity to climate change. Sorghum plays an important role in food security in some of the poorest parts of the world. This article reviews the literature to identify and examine the major factors affecting sorghum production in three major production regions. Factors were not categorized ex ante but rather determined from the review. Ten major factors were identified as having notable impacts on sorghum production: climate change, population growth/economic development, non-food demand, agricultural inputs, demand for other crops, agricultural resources scarcity, biodiversity, cultural influence, price and armed conflict. This synthesis revealed that (1) multiple factors simultaneously affect sorghum production; (2) the effect of each factor is greatly influenced by the magnitude and certainty of one or more other factors; and, (3) factors differ in relevance and degree with regard to geography. Generally, improved agricultural inputs, population growth/economic development and climate change have substantial influence on sorghum production. However, local dynamics likely go beyond these broad trends and more exhaustive, locally-focused studies are needed for actionable planning purposes.

Although the transition to industrial agriculture in the 20th century resulted in increased agricultural productivity and efficiency, the attainment of global food security continues to be elusive. Current and anticipated impacts of climate change on the agricultural sector are likely to exacerbate the incidence of food insecurity. In recent years, climate-smart agriculture has gained recognition as a mechanism that has the potential to contribute to the attainment of food security and also enhance climate change mitigation and adaptation. However, several conceptual and implementation shortfalls have limited the widespread adoption of this innovative agricultural system at the landscape scale. This manuscript argues for the use of ecosystem management as an overarching framework for the conceptualization and implementation of climate-smart agriculture. The manuscript focuses on clarifying the foundational assumptions and management goals, as well as the knowledge and institutional requirements of climate-smart agriculture using the principles of ecosystem management. Potential challenges that may be faced by the application of an ecosystem management approach to climate-smart agriculture are also discussed. Furthermore, the manuscript calls for a heightened focus on social equity in the transition toward an ecosystem-based approach to climate-smart agriculture. The US farm bill is used as an illustrative case study along with other examples drawn mostly from sub-Saharan Africa.

The growing realization of the inadequacies of the conventional approach to climate change adaptation has generated interest in sustainable forms of adaptation that could promote long-term ecosystem health and social equity. In this regard, the concept of ecosystem-based adaptation has been receiving attention as an integrative framework for maintaining healthy ecosystems, with the aim of building the resilience and reducing the vulnerability of social–ecological systems to climate change impacts. However, there is currently an inadequate understanding of the institutional requirements for the transition towards ecosystem-based adaptation. A promising institutional mechanism for addressing these governance challenges is adaptive governance, a governance mechanism that relies on flexible, multi-level institutions to connect actors across multiple scales in managing conflicting values and uncertainties in ecosystem-based management processes. This paper discusses four roles of adaptive governance in the transition of water resource systems towards ecosystem-based adaptation: (1) creating awareness about climate change through social learning and the integration of diverse sources of knowledge; (2) generating interest for policy change through the provision of economic and non-economic incentives; (3) creating opportunities for change through the promotion of vertical and horizontal interactions among actors; and (4) building capacities for change through enhanced access to relevant institutions and resources.

Since the late 1980s, the idea of sustainable development has been gaining widespread recognition as a guiding framework for policies on development and the environment. However, the concept of sustainable development has received a number of criticisms, including its over-emphasis on meeting human needs through economic growth, as well as its failure to recognize dynamic human–environment interactions. In response to these shortfalls, the concepts of resilience and adaptive governance have emerged as alternative perspectives for pursuing sustainable development. Resilience in social-ecological systems emphasizes the capacity of coupled human–environment systems to deal with change, while continuing to develop. Adaptive governance relies on diverse and nested institutional mechanisms for connecting actors across multiple scales to manage conflicts and uncertainties in ecosystem management processes. However, the ethical dimensions of resilience and adaptive governance have not received enough attention. A promising ethical perspective for guiding policies on human–environment interactions is the philosophy of deep ecology, which highlights the need for recognition of the intrinsic values of all living things, as well as the nurturing of ecological and cultural diversity. In this paper, I argue that an integration of the principles of deep ecology and adaptive governance provides a complementary set of ethical principles and institutional attributes that offers better prospects for pursuing sustainable development in the era of the Anthropocene. The implications of this integrative agenda include: the adoption of a holistic conception of dynamic human–environment interactions; the recognition of diverse knowledge systems through an anti-reductionist approach to knowledge; the promotion of long term sustainability through respect for ecological and cultural diversity; and embracing decentralization and local autonomy. I further illustrate this integrative agenda using the management of protected areas as a case study.
