“…In addition to advancing food security, agroforestry can also enhance multiple social dimensions of the SDGs. It provides a pathway out of poverty (a major driver of hunger itself; World Bank, 2015) because the combination of increased yield, low cost, and additional tree-based farm products can significantly increase net farm income (Miller, Munoz-Mora, & Christiaensen, 2017;Reyes, Quiroz, & Msikula, 2005;Waldron, Justicia, Smith, & Sanchez, 2012). In addition, farmer movements in the developing world have expressed a lack of equity and dignity (SDGs 10, 8, and 16) in the way their livelihoods can be negatively affected by distant supply-chain actors, and so have sought greater local control of food production (e.g., ''food sovereignty''; Chappell et al, 2013;Desmarais, 2007;Whitmann, 2011), see also (Cook, Silici, Adolph, & Walker, 2015;Thorlakson & Neufeldt, 2012).…”

To achieve global food security, we need to approximately double food production over the coming decades. Conventional agriculture is the mainstream approach to achieving this target but has also caused extensive environmental and social harms. The consensus is that we now need an agriculture that can ''multi-functionally'' increase food production while simultaneously enhancing social and environmental goals, as committed to in the sustainable development goals (SDGs). Farming also needs to become more resilient to multiple insecurities including climate change, soil degradation, and market unpredictability, all of which reduce sustainability and are likely to exacerbate hunger. Here, we illustrate how agroforestry systems can increase yield while also advancing multiple SDGs, especially for the small developing-world agriculturalists central to the SDG framework. Agroforestry also increases resilience of crops and farm livelihoods, especially among the most vulnerable food producers. However, conventional yield-enhancement strategies have naturally dominated the debate on food production, hindering implementation of more multifunctional alternatives. Governments and institutions now have the opportunity to rebalance agricultural policy and investment toward such multigoal approaches. In doing so, they could achieve important improvements on multiple international commitments around the interlinked themes of food security, climate change, biodiversity conservation, and social well-being.

“…There is also potential for restoration in these areas to benefit human communities. For example, trees on farms can provide significant co-benefits to farmers by serving as additional sources of food and income [77], and by providing beneficial ecosystem services (e.g. soil microbes and pollination; [78]).…”

Effective restoration planning tools are needed to mitigate global carbon and biodiversity crises. Published spatial assessments of restoration potential are often at large scales or coarse resolutions inappropriate for local action. Using a Tanzanian case study, we introduce a systematic approach to inform landscape restoration planning, estimating spatial variation in cost-effectiveness, based on restoration method, logistics, biomass modelling and uncertainty mapping. We found potential for biomass recovery across 77.7% of a 53 000 km 2 region, but with some natural spatial discontinuity in moist forest biomass, that was previously assigned to human causes. Most areas with biomass deficit (80.5%) were restorable through passive or assisted natural regeneration. However, cumulative biomass gains from planting outweighed initially high implementation costs meaning that, where applicable, this method yielded greater long-term returns on investment. Accounting for ecological, funding and other uncertainty, the top 25% consistently cost-effective sites were within protected areas and/or moderately degraded moist forest and savanna. Agro-ecological mosaics had high biomass deficit but little cost-effective restoration potential. Socio-economic research will be needed to inform action towards environmental and human development goals in these areas. Our results highlight value in long-term landscape restoration investments and separate treatment of savannas and forests. Furthermore, they contradict previously asserted low restoration potential in East Africa, emphasizing the importance of our regional approach for identifying restoration opportunities across the tropics. This article is part of the theme issue ‘Understanding forest landscape restoration: reinforcing scientific foundations for the UN Decade on Ecosystem Restoration’.

“…A fracção, na altura correspondia a cerca de 35.000 toneladas e 1,4 kg de consumo per capita. Em muitos países africanos, a porção vendida dos produtos arbóreos tende a superar aquela que é consumida (Miller et al, 2018).…”

“…Portanto, o relativo acréscimo do 'consumo doméstico' que leva à igualdade com o volume comercializado, neste estudo, se deve ao facto de que o volume de 'consumo doméstico' inclui o volume de venda não registada pelas autoridades, principalmente para os países vizinhos como a Eswathini e África do Sul, pelas fronteiras terrestres. Na Nigéria, um equilíbrio similar, de 50% entre a venda e consumo doméstico, foi reportado em espécies arbóreas de rendimento incluindo o caju (Miller et al, 2018).…”

A adopção de subsídios na agricultura é tema de debate internacional. No entanto, na década de 1990, Moçambique optou pela política de subsídios na cadeia de produção do caju visando a recuperação da produção e da indústria. Neste estudo, objetivou-se entender como esta política impactou a produção, compreender os desafios e lições da retirada dos subsídios e liberalização do mercado de equipamentos de aplicação de pesticidas. Por amostragem, conduziram-se entrevistas estruturadas a 355 beneficiários diretos de subsídios no tratamento químico dos cajueiros. O conteúdo das entrevistas incluiu entre outros, o perfil demográfico, tipo e fonte de equipamento, ano e números de aquisições e eficiência do serviço provido. Do arquivo do IAM-IP acrescentou-se o número de beneficiários do programa e da produção comercializada da castanha. Os dados foram tratados com base em estatística descritiva, construindo gráficos de distribuição de frequências e correlações usando Excel. Os resultados indicam que a política de subsídio alcançou 14% do universo de agregados familiares de produtores de caju e impulsionou a produção comercializada de 50 mil toneladas para triplo. Gerou 9.208 empregos permanentes para homens (95%) na faixa dos 46 a 60 anos (49%) e com escolaridade heterogénea. A retirada de subsídios e liberalização de equipamentos expandiu a aquisição de máquinas minorando a sua qualidade. Portanto, num sistema de mercado liberalizado a reorientação dos subsídios deve servir para regulamentar o tipo de equipamento, melhorar a fiscalidade de qualidade, eficiência de aplicação. Esta lição pode ser extrapolada para subsídios na aquisição de pesticidas.
