    Cropping system diversification in Eastern and Southern Africa: Identifying policy options to enhance productivity and build resilience 2018

    Crop diversification is an important policy objective to promote climate change adaptation, yet the drivers and impacts of crop diversification vary considerably depending on the specific combinations of crops a farmer grows. This paper examines adoption determinants of seven different cropping systems in Malawi, Zambia and Mozambique, and the impact of their adoption on maize productivity and income volatility – using a multinomial endogenous treatment effect model. These cropping systems consist in different combinations of four categories of crops: dominate staple (maize), alternative staples, legumes, and cash-crops. The study finds that relative to maize mono-cropping systems, the vast majority of systems have either neutral or positive effects on maize productivity, and either reduce or have neutral effects on crop income volatility. In particular, cropping systems that include legumes produce better outcome in most cases than those that feature cash crops. From a policy perspective, three recurrent determinants of diversification are found. First, private sector output market access is an important driver of diversification out of maize mono-cropping. Policies crowding in private output market actors can help to promote a wide range of more diverse cropping systems. Second, proximity to public marketing board buying depots discourages the adoption of more diverse cropping systems. Therefore, reforms to these institutions must be part of any diversification strategy. Finally, in all countries and for all systems, land size is a key determinant of adopting more diverse systems. Thus, land policy is an integral element of any boarder diversification strategy.

    Sustainable Livelihoods and Climate Resilience through Climate Smart Agriculture (CSA) and Agroforestry (AF) Best Practices in the Northwestern Mountainous Region of Viet Nam - TCP/VIE/3701 2023

    The six northwestern provinces of Viet Nam Hoa Binh Son La, Dien Bien, Lai Chau, Yen Bai and Lao Cai are endowed with rich natural resources that play a crucial role in watershed management for such key river systems as the Da and Ma rivers The six provinces cover a total land area of approximately 5 64 million ha and provide a home to 4 43 million people, of whom 3 35 million are ethnic minorities The provinces are among the poorest regions of the country, with more than 80 percent of the population dependent on agriculture for its livelihood The region has 3 9 million ha of agriculture and forestry land, of which 80 percent is dedicated to forestry and 20 percent to farming In addition to the effect of population pressure on arable land, the expansion of agricultural production onto hilly and sloping land, and the prevalence of maize mono cropping have caused serious deforestation, the degradation of agro ecosystems and landscape fragmentation In addition, the region is characterized by fragile ecosystems, unstable geology and complex topography, and is highly vulnerable to climate change and natural disasters Despite this crucial situation, the introduction of important counter measures, such as tree based intercropping, remains limited Barriers to the large scale adoption of such practices in the region include widespread outdated cultivation practices, a lack of knowledge of climate smart agriculture ( and agroforestry ( practices and significant investment requirements In addition, given the prevalence of monoculture, there is little incentive for farmers, who have limited access to education and an extension system, to diversify their income The aim of the project was thus to enhance the capacities of the government and upland communities to scale up CSA/AF best practices in the Northwestern Mountainous Region of Viet Nam.

    Resilience Building in Madagascar
    FAO Programme Review 2024

    The FAO Regional Office for Africa (RAF) collaborates with several African countries in Africa, including Madagascar, to enhance resilience building efforts. In Madagascar FAO is employing an integrated approach to restore and enhance the food production as well as diversify the di¬ets of the communities. Support includes production of short-cycle vegetables, early maturing, and climate-re¬silient varieties of pulses and cereals, and small livestock (poultry and small ruminants), while increasing farmers access to agriculture inputs and sensitizing them to biolog¬ical control of plant pest and diseases. Emphasis is made to include climate-smart agriculture and nutrition sensitive agriculture, combined with sustainable water solutions. To protect and enhance livestock-based livelihoods, livestock vaccination and treatment campaigns are be¬ing scaled up. This includes awareness creation on com¬mon animal disease outbreaks and control but above all, during training sessions, the emphasis is on a prophy¬lactic approach. Furthermore, FAO Madagascar supports the Government in the fight against antimicrobial resistance (AMR). Finally, efforts are being made to rebuild herds and diversify livelihoods through restocking measures, along with en¬hanced animal health services and robust surveillance of common livestock diseases. Through solar pump irrigation systems, FAO is working with communities to build water infrastructure to in¬crease access and availability of water resource for agri¬cultural production and livestock. FAO is also providing support to the Government of Madagascar to strengthen Food Security and Nutrition information analysis and co¬ordination for improved preparedness and response. The food security, nutrition and climate information systems are being reinforced with a focus on strengthening part¬nerships with national and the Southern Africa Devel¬opment Community (SADC). , This document reflects an analysis of ongoing FAO Madagascar resilience building interventions and how they contribute towards the five capacities for resilience building, namely: Preventive: reduce existing and future risks; Anticipative: act early; Absorptive: the ability to bounce back, overwhelmingly humanitarian (emergency response); Adaptive: incremental adjustments; Transformative: make fundamental changes to the system. The five capacity areas are in most cases overlapping during specific project implementation, with the classification based on the overarching resilience capacity area.
