Showing how emissions can be brought to zero by mid-century stay within the small remaining carbon budget for limiting global warming to 1.5°C.

This chapter assesses mitigation pathways consistent with limiting warming to 1.5°C above pre-industrial levels. In doing so, it explores the following key questions: What role do CO2 and non-CO2 emissions play? To what extent do 1.5°C pathways involve overshooting and returning below 1.5°C during the 21st century? What are the implications for transitions in energy, land use and sustainable development? How do policy frameworks affect the ability to limit warming to 1.5°C? What are the associated knowledge gaps?

The launching of Sanitary and Phytosanitary border inspection took place on the 10th of January 2019 at the Department of Agricultural Research (DAR) Maseru, Lesotho. This event was graced by the presence of the Principal Secretary (P.S) of the Ministry of Agriculture and Food Security, SADC Trade Related Facility (TRF) Coordinator, EU Representative, Lesotho Revenue Authority (LRA)-Deputy Commissioner of Customs, Lesotho National Farmers Union (LENAFU), Representatives from the private sector and other government officials.

This chapter frames the context, knowledge-base and assessment approaches used to understand the impacts of 1.5°C global warming above pre-industrial levels and related global greenhouse gas emission pathways, building on the IPCC Fifth Assessment Report (AR5), in the context of strengthening the global response to the threat of climate change, sustainable development and efforts to eradicate poverty.

Climate change is projected to have serious impacts on the agriculture of southern Africa, affecting food availability, creating local production shortfalls and resulting in rising commodity prices. This report highlights the risks to agriculture and food systems that may occur in two counties of the region, Malawi and Zambia. The analysis uses the conceptual framework of climate-related risk from the Fifth Assessment Report of the Intergovernmental Panel on Climate Change to examine the impacts that climate change is likely to have on agriculture and food security. Country-specific trends in temperature and rainfall and projected impacts are summarised from the literature. The vulnerability of the agricultural sector in each country is discussed in relation to its sensitivity to change and coping and adaptive capacity, and the risks of climate change on agriculture and small-scale farmers in the two focus countries assessed. A prioritisation process is then carried out to rank different commodities in each country, with respect to four dimensions: the importance of the commodity to the economy of the country, the national yield gap compared with the regional average, the importance of the commodity in people’s diet, and the projected impact of climate change on yield. The results of the analysis highlight three commodities that could be prioritized for agricultural development interventions: maize, potatoes and beans in Malawi, and maize, pulses and sorghum in Zambia.

This volume shares new data relating to Climate-Smart Agriculture (CSA), with emphasis on experiences in Eastern and Southern Africa. The book is a collection of research by authors from over 30 institutions, spanning the public and private sectors, with specific knowledge on agricultural development in the region discussed. The material is assembled to answer key questions on the following five topic areas: (1) Climate impacts: What are the most significant current and near future climate risks undermining smallholder livelihoods? (2) Varieties: How can climate-smart varieties be delivered quickly and cost-effectively to smallholders? (3) Farm management: What are key lessons on the contributions from soil and water management to climate risk reduction and how should interventions be prioritized?  (4) Value chains: How can climate risks to supply and value chains be reduced? and (5) Scaling up: How can most promising climate risks reduction strategies be quickly scaled up and what are critical success factors? Readers who will be interested in this book include students, policy makers, and researchers studying climate change impacts on agriculture and agricultural sustainability.

A study was conducted to determine the influence of climate variability on livestock population dynamics in Kgalagadi district. Data on NAO, ENSO and SSTs indices were regressed and correlated against regional rainfall for kgalagadi region and livestock populations. Regional rainfall data was also related to livestock population dynamics. The results suggested that NAO, ENSO and SSTs were not good predictors of regional rainfall variability and livestock population dynamics (P > 0.05). The regional rainfall was highly variable and accounted for fluctuations on cattle and goat populations (P < 0.05) but not sheep population. Goat population appeared more sensitive to rainfall variability than other livestock species. Cattle death rate was also strongly influenced by rainfall variability whereas other livestock performance indicators were not significantly accounted for by rainfall variability. The results suggest that management need to be improved to buffer impact of climate variability on livestock population.

The eastern communal conservancies are situated along the western fringe of the Kalahari basin. Under a very short rainfall gradient, the vegetation abruptly changes from microphyllous Acacia-dominated savannas to mesophyll savannas, dominated by Terminalia sericea and Combretum spp. We hypothesise that this is caused by changes in soil moisture availability brought about by changes in soil texture from loamy soils to deep sands (the ‘inverse texture effect’). For this analysis, we used vegetation and soils data derived from a recognisance survey of the natural resources of the study area. As the sites in the soil and vegetation surveys did not overlap, it was decided to use only synoptic data for the plant associations in the analysis. Non-metric multidimesional scaling ordination was utilised as ordination technique of the vegetation data and various environmental parameters, including soil texture, soil hydraulic parameters, climatic and fire regime parameters, were overlaid as biplots onto the resulting graph, as were various plant functional attributes particularly related to climatic conditions. The main environmental gradient identified within the study area is the rainfall gradient. This relatively short gradient, however, does not explain the marked change in vegetation observed within the study area. This change is attributed to the change in soil type, in particular, the soil texture and the associated soil hydraulic parameters of the soil. This gradient is closely correlated to leaf size, explaining the change from microphyll savannas to mesophyll savannas along the change from loamy to sandy soils. One of the lesser understood mechanisms for the survival of these mesophyll plants on sandy soils seems to be a deep root system, which is actively involved in water redistribution within the soil profile – by hydraulic lift, inverse hydraulic lift and stem flow.
