At the heart of the Mountain Kingdom of Lesotho lie the highlands. Sitting between 2000 and 3500 metres above sea level, they channel water into the OrangeSenqu River which winds its way from Lesotho through South Africa and Namibia, with tributaries stretching as far as Botswana. It is a key source of water for Southern Africa’s most economically active region, supporting large-scale irrigation, industrial activities, hydropower, urban demand, and small-scale rural activities. South Africa’s highly developed economy draws most of the water, with Gauteng deriving over 32% of its water directly from Lesotho. This paper is a discussion of this resource base.

The brief discusses the key messages that transpired during the Conference on Scaling held on 29─30 November 2018 at the Melia Hotel in Hanoi, hosted by CCAFS SEA, co-hosted by ACIAR and GIZ, and funded by a CCAFS Small Grant Cross-CRP Networking. The conference main points include: scaling up agricultural innovations takes place in complex systems of agricultural transformation, and sustainable scaling should build into “sustainable change at scale”.

This booklet presents a collection of previously unpublished or ongoing research and interventions related to climate-smart agriculture (CSA), with emphasis on experiences in Eastern and Southern Africa. The visual material contained herein offers researchers, development workers and policy-makers teaser insights into new tools, methodologies and data to support CSA scaling efforts. The 35 contributions in this booklet answer to five key questions that currently obstruct the efficient and effective implementation of CSA agendas.

In an effort to serve as a 'one stop shop' for climate-related information, data, and tools, the World Bank created the Climate Change Knowledge Portal (or CCKP). The Portal provides an online tool for access to comprehensive global, regional, and country data related to climate change and development.

alawi is a landlocked country in Southern Africa, with an economy driven predominantly by the agricultural sector that accounts for one third of the GDP and nearly 80 percent of employment. Agriculture is considered the engine of Malawi’s economic growth since, between 2005 and 2011, more than 80 percent of the country’s total exports were agricultural commodities, primarily tobacco, sugar and tea. Tobacco alone however, represents an average 60 percent of Malawi ́s total exports.1 The manufacturing and agricultural sectors work together in their contribution to the overall growth of the economy, which in 2013/14, registered an average GDP growth rate of 5.2 percent. In particular, the 2013 growth in manufacturing was attributed to usage of higher volumes of raw agricultural inputs and a more constant supply of fuel and other raw materials.

The topics assessed in this chapter were last assessed by the IPCC in 2007, principally in WGII AR4 Chapters 3 (Kundzewicz et al., 2007) and 4 (Fischlin et al., 2007), but also in WGII AR4 Sections 1.3.4 and 1.3.5 (Rosenzweig et al., 2007). The WGII AR4 SPM stated “Observational evidence from all continents and most oceans shows that many natural systems are being affected by regional climate changes, particularly temperature increases,” though they noted that documentation of observed changes in tropical regions and the Southern Hemisphere was sparse (Rosenzweig et al., 2007). Fischlin et al. (2007) found that 20 to 30% of the plant and animal species that had been assessed to that time were considered to be at increased risk of extinction if the global average temperature increase exceeds 2°C to 3°C above the preindustrial level with medium confidence, and that substantial changes in structure and functioning of terrestrial, marine, and other aquatic ecosystems are very likely under that degree of warming and associated atmospheric CO2 concentration. No time scale was associated with these findings. The carbon stocks in terrestrial ecosystems were considered to be at high risk from climate change and land use change. The report warned that the capacity of ecosystems to adapt naturally to the combined effect of climate change and other stressors is likely to be exceeded if greenhouse gas (GHG) emission continued at or above the then-current rate.

Changes in the hydrological cycle due to climate change can lead to diverse impacts and risks, and they are conditioned by and interact with non-climatic drivers of change and water management responses (Figure 3-1). Water is the agent that delivers many of the impacts of climate change to society, for example, to the energy, agriculture, and transport sectors. Even though water moves through the hydrological cycle, it is a locally variable resource, and vulnerabilities to water-related hazards such as floods and droughts differ between regions. Anthropogenic climate change is one of many stressors of water resources. Nonclimatic drivers such as population increase, economic development, urbanization, and land use or natural geomorphic changes also challenge the sustainability of resources by decreasing water supply or increasing demand. In this context, adaptation to climate change in the water sector can contribute to improving the availability of water.

This chapter addresses the foundations of decision making with respect to climate impact, adaptation, and vulnerability (CIAV). The Fourth Assessment Report (AR4) summarized methods for assessing CIAV (Carter et al., 2007), which we build on by surveying the broader literature relevant for decision making.
