Aims Climate and human impacts are changing the nitrogen (N) inputs and losses in terrestrial ecosystems. However, it is largely unknown how these two major drivers of global change will simultaneously influence the N cycle in drylands, the largest terrestrial biome on the planet. We conducted a global observational study to evaluate how aridity and human impacts, together with biotic and abiotic factors, affect key soil variables of the N cycle. Location Two hundred and twenty‐four dryland sites from all continents except Antarctica widely differing in their environmental conditions and human influence. Methods Using a standardized field survey, we measured aridity, human impacts (i.e. proxies of land uses and air pollution), key biophysical variables (i.e. soil pH and texture and total plant cover) and six important variables related to N cycling in soils: total N, organic N, ammonium, nitrate, dissolved organic:inorganic N and N mineralization rates. We used structural equation modelling to assess the direct and indirect effects of aridity, human impacts and key biophysical variables on the N cycle. Results Human impacts increased the concentration of total N, while aridity reduced it. The effects of aridity and human impacts on the N cycle were spatially disconnected, which may favour scarcity of N in the most arid areas and promote its accumulation in the least arid areas. Main conclusions We found that increasing aridity and anthropogenic pressure are spatially disconnected in drylands. This implies that while places with low aridity and high human impact accumulate N, most arid sites with the lowest human impacts lose N. Our analyses also provide evidence that both increasing aridity and human impacts may enhance the relative dominance of inorganic N in dryland soils, having a negative impact on key functions and services provided by these ecosystems.

“…Although all farming systems require managerial expertise, technical knowledge and organisational skills to varying degrees, greenhouse horticulture is particularly demanding (see Aznar‐Sánchez and Galdeano‐Gómez ). Interviewees attribute the failure over the last years to the lack of these skills of a small number of newcomers with non‐agricultural background that have entered from other sectors of the local economy affected by the crisis.…”

This article endeavours to illuminate a largely underexplored area of family farming research; that of multiple‐household arrangements at the farm level. The investigation focused on an agricultural area of south‐east Spain where family‐based farms specialising in export‐oriented horticulture have undergone profound transformations over the last decades. In‐depth interviews were undertaken with 20 informants complemented by a face‐to‐face survey of 135 farmers. A closer look at the farm–family interplay unveiled the existence of holdings jointly managed by several kindred households. These farm governance structures are associated with a greater ability to cope with the managerial complexity of this agricultural system and provide a sound basis for farm expansion, thus emerging as an important element of farm differentiation. Micro‐level information allowed us to explore, for the first time, the variable morphology of the organisational forms that were often found to lie behind different legal arrangements and their role in the intergenerational transfer process. These findings have far‐reaching implications for research, since they take us considerably beyond the picture portrayed by conventional agricultural statistics and challenge many of the traditional assumptions and categories of the existing literature on family farming.

“…Further, the proponents of the cluster theoretical framework argue that diffusion of production capabilities is not only limited to GVC participants, but there is also knowledge and skills "spillover" in a geographical area and/or localities of business operations [8,[21][22][23][24][25][26]. They argued that impact of knowledge and skills "spillover" accounts for the rise of entrepreneurship in various forms such as functional upgrading, new entrants in the existing clusters and value chains, and the start of new parallel competitive value chains.…”

This research employed an explanatory case study to compare supplier production capabilities for enhancing productivity gains between Uganda commercial forestry and sugarcane sector value chains. Key study results indicated that only 18% of the sugarcane farmers achieved the desired industry productivity output of at least 100 t/ha from their fields, with majority (82%) of the cane growers producing below expected industry productivity output. In the forestry sector, 41.3% of the farmers achieved the desired industry performance targets, with 58.7% of the growers performing below expected performance targets. The major buyers' supplier development behaviour as seen in the diffusion of knowledge, skills and appropriate technology along vertical and horizontal collaborative value chain relationships, explains this paradox. Millers in the sugarcane sector used contractors to diffuse knowledge and skills, which weakened the supplier production capabilities. In the forestry sector, with the support of development partner agencies, productivity was higher due to effective diffusion of knowledge, skills and appropriate technology to primary producers. This finding strongly points to the need to implement deliberate supplier development strategies by the development partner agencies and governments, if productivity gains are to be improved within the agri-business value chains in developing countries.
