Governments in sub-Saharan Africa promote the expansion of irrigation to improve food security, primarily through the adoption and use of groundwater-based smallholder private irrigation. Using the case of Ethiopia, we examine farmers’ willingness to adopt smallholder private irrigation packages in response to subsidies on pump prices, loan availability and reduction in ambiguities related to borehole drilling. The results of the research highlight that subsidizing pump prices may not be the best use of public funds to expand irrigation.

This chapter highlights the key dependences, linkages and challenges of water resources management. (Many of these issues discussed are revisited and illustrated in the following chapters.) The first part introduces surface and groundwater management in the terrestrial part of the water cycle. Comprehensive presentations of key hydrological phenomena and processes, monitoring, assessment and control are followed by overviews of dependences, linkages and challenges. The manifold facets of intensive human/resource interaction and inherent threats to the resources base are exposed.

This synthesis brief draws on the experiences of the Restoring Degraded Landscapes sub-program, part of the CGIAR Research Program on Water, Land and Ecosystems (WLE). The brief captures learning from a decade (2011-2021) of research in development work with different stakeholders including farmers and governments across the world to reverse landscape degradation. It provides an overview of effective approaches, innovations and solutions that can be taken forward and scaled up to meet current and future challenges from land degradation – as well as the opportunities that may arise.

Value chain for development (VCD) has increasingly been promoted for poverty reduction; yet, there is inadequate evidence on its effectiveness. Based on a comprehensive literature review, this article offers reasons why evidence on VCD impacts on poverty reduction is uncertain. It also suggests a conceptual framework for the poor-centred value chain for sustainable development to guide a better analysis of VCD participation and poverty impacts. The framework is particularly useful for researchers involved in research for development related projects in the VCD space.

Brazil has transformed from being a net food importer, to one of the largest agricultural exporters in the world. The country is now one of the top global funders of agricultural innovation, with a special emphasis on funding R&D for sustainable agriculture. While food insecurity and environmental challenges exist in many parts of Brazil, social programs and funding in innovation have helped those in need.

Water markets are a potential approach for reallocating and improving the efficiency of water use in river basins in which water resources are under stress as a consequence of demographic and economic pressures. However, establishing water markets is not easy and to be successful a wide range of context specific criteria, relating to the legal and institutional framework as well as political and economic conditions, must be met. We applied the Water Market Readiness Assessment framework proposed by Wheeler et al.

Controlled Environment Agriculture (CEA) is the production of plants, fish, insects or animals inside structures, such as greenhouses and buildings, in controlled conditions. In a rapidly urbanizing world, CEA can contribute to sustainable development, e.g. through reduced use of land, water and inputs. There is a need for innovation in policy, technology and business practices to scale up CEA in the Global South sustainably and equitably.

Landscape Approaches have been proposed as a transferable model of multi-stakeholder governance, yet assume conditions of ideal speech, trust, and transparency that seem untransferable to authoritarian regimes. This paper argues that building Landscape Approaches under authoritarian conditions cannot be based on a governance deficit model of awaiting idealized political conditions, but instead needs to pay attention to how local social and political structures influence what is deliberated, and by whom.

Indonesia has experienced one of the world's fastest plantation expansions. Plantation growth is indeed an economic solution to meet the market's needs, but the accompanying environmental damage and social conflict are at odds with sustainability goals. Various actors with interests in land compete with the power they have. The most powerful actors have controlled land use based on their decisions. Accordingly, this paper presents empirical evidence to understand the important role of powerful actors in land-use contestation in oil palm and industrial plantation forests.
