Sustainable agriculture is a discipline that addresses current issues such as climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, and social sciences. Indeed, sustainable agriculture decipher mechanisms of processes that occur from the molecular level to the farming system to the global level at time scales ranging from seconds to centuries. For that, scientists use the system approach that involves studying components and interactions of a whole system to address scientific, economic and social issues. In that respect, sustainable agriculture is not a classical, narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. Because most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world. This book series gathers review articles that analyze current agricultural issues and knowledge, then propose alternative solutions. It will therefore help all scientists, decision-makers, professors, farmers and politicians who wish to build a safe agriculture, energy and food system for future generations.

Four major intensification systems to achieve sustainable agriculture have been identified: conventional with high input, organic, agroecological and eco-technical ‘sustainable intensive’. Those systems display advanced crop protection. Here we review the performance of those systems in the context of sub-Saharan Africa. The major points are: (1) Unlike economies of Europe and North America following World War 2, and of Asia and Latin America following the Green Revolution, sub-Saharan Africa rural economies were not transformed by conventional intensification involving cultivation of cash crops for export and over-reliance on pesticides. Genetically modified crops were used only to a limited extent at the regional level. (2) Most staple food-based cropping systems are de facto organic due to the unavailability of synthetic inputs. Organic systems are thus developing for some export cash crop sectors, with synthetic pesticides are being substituted by non-chemical pesticides. (3) Agroecological crop protec- tion focuses on biological pest regulations such as the replacement of chemical inputs, thus implying the re-design of cropping systems. (4) For crop protection, the eco-technical pathway, which is based on principles of integrated pest management and ecological intensification, is more flexible and pragmatic than the other sys- tems. In this review we compare the different systems, notably their contribution to six ecosystem services connected with crop protection issues: biomass production, pest and disease regulation, maintenance of water quality, biodiversity conserva- tion, pollination and climate change mitigation. We then identify research needs in the context of food security, urbanization, trade globalization and climate change.

Since the end of World War 2, world agriculture has been characterized by an intensification of practices, in view of meeting significantly increased crop production needs. This trend is particularly marked in Northern countries, but has also affected developing countries in the Southern Hemisphere, as further promoted by the Green Revolution concept, advocating massive use of mostly external non-renewable inputs (mineral fertilizers, chemical pesticides, fossil fuels), along with improved crop cultivars and irrigation (Pingali 2012). However, while Green Revolutions transformed rural economies of many Asian and Latin American countries during the last four decades of the twentieth century, the transfer of the same strategies to sub-Saharan Africa (SSA) had limited success (Dawson et al. 2016). 1 Crop Protection for Agricultural Intensification Systems in Sub-Saharan Africa 3 The sustainable agriculture movement started about a decade later, mainly with a view to counteracting pesticide misuse and abuse (mainly a crop protection issue). Integrated pest management (IPM) was probably the first among the several con- cepts that emerged during the second half of the last century as a pathway toward sustainable agriculture, based on the perceived need to break away from the domi- nant paradigm that gave rise to an intensive type of agriculture associated with arti- ficial conditions, biodiversity reduction and reliance on non-renewable and toxic inputs (Ratnadass and Barzman 2014). However, in sub-Saharan Africa (SSA), where family farming is dominant, pesticides are seldom used on staple food crops (but with the notable exception of cowpea and irrigated rice) but instead are reserved for high value cash crops, particularly cotton (Deguine et al. 2008), cocoa (Ayenor et al. 2004), and fruits and vegetables (Ahouangninou et al. 2011; de Bon et al. 2014). Crop pests are still a major constraint to the intensification of agricultural crop- ping systems, especially in tropical areas. In SSA, they notably restrict the adoption of improved crop cultivars that are higher yielding but generally more susceptible to biotic stresses than conventional varieties, unless pesticides are used. The recently concluded PROIntensAfrica initiative (Sourisseau et al. 2016; Windmeijer et al. 2017) identified four major pathways toward sustainable agriculture for SSA, including the high-input (or conventional) pathway, the organic pathway, the agro- ecological pathway, and the eco-technical (or sustainable intensive agriculture) pathway. With reference to the recent review by Thérond et al. (2017), the high-input/ conventional and the organic pathways respectively correspond to chemical input- based and biological input-based farming systems. On the other hand, both the agro- ecological and eco-technical/sustainable agriculture pathways roughly correspond to biodiversity-based farming systems, due to overlaps in terms of definitions, prin- ciples and practices (Wezel et al. 2015). The major difference between the latter two pathways is the mainstreaming of cultural and social perspectives in the agroeco- logical concept. The eco-technical concept lacks these perspectives, while it shares ecological intensification principles with the agroecological concept (but in a nar- rower sense, i.e. closer to that expressed by Cassman (1999) or Tittonell and Giller (2013), than by Doré et al. (2011) and Bonny (2011)), but combined with some options of the high-input/conventional concept. Based on the three category-based typology proposed by Dupré et al. (2017), the “high-input/conventional” pathway clearly falls within the “synthetic inputs” cate- gory, and the agroecological pathway within the “alternative on-farm inputs” cate- gory. On the other hand, the organic pathway falls in-between the “alternative off-farm inputs” and the “alternative on-farm inputs” categories, while the “eco- technical/sustainable agriculture” pathway cuts across all three categories, being more biased towards the “alternative on-farm inputs” category though. More specifically, all four identified pathways have well-developed crop protec- tion dimensions (Gurr et al. 2004; Zehnder et al. 2007; Deguine and Penvern 2014; Ratnadass and Barzman 2014; Deguine et al. 2017). They share several manage- ment options, including the use of chemical pesticides and genetically modified plants (with the notable exceptions of the organic pathway for both options, and of the agroecological and organic pathways for the latter). On the other hand, IPM
