Aim of study: A two-year experiment (2021-2022) was conducted to assess the response of a local maize hybrid BL-43 to different water regimes (full irrigation, deficit irrigation and rainfed) at two distinguished pedo-climatic locations (Aleksandrovac and Butmir) in Bosnia and Herzegovina (BiH). Area of study: The field experiment was located in Aleksandrovac (near Banja Luka) and Butmir (near Sarajevo) in BiH. Material and methods: A randomized block design was adopted at both experimental locations with three replicates. An Excel-based irrigation tool was used to manage crop water requirements and irrigation scheduling. Main results: Crop response to water was affected by site-specific agronomic management, the duration of phenological stages and their interconnection with precipitation events. At both locations, the effect of the water inputs on grain yield was statistically significant confirming the beneficial impact of irrigation. The effect of water stress on yield was particularly pronounced at Aleksandrovac, which was under water and temperature stresses during flowering time. During both seasons and for all water regimes, the total average grain yield was greater at Butmir than at Aleksandrovac for 38% and 27%, respectively. Research highlights: This is the first experimental study conducted in BiH on the effect of irrigation on maize grain production under different pedoclimatic conditions. The study emphasizes the need for knowledge regarding the impacts that climate change is having on the productivity of one of the region's most important crops.

Bosnia and Herzegovina (BiH) accumulates challenges in the areas of research and innovation (R&I), agricultural water management (AWM) and their intersection. In the decade 2012–2022, the BiH gross domestic product per capita in current US$ increased by 6.2% annually. However, improvements are slowly arriving in R&I and AWM. In this period, relevant challenges to AWM have materialized, such as climate change effects or the need to implement an interconnected vision of ecosystem services. In the R&I arena, the societal demand for knowledge goods remains low, while the reforms of higher education and R&I funding systems have become urgent. This paper set out to elaborate a realistic and feasible policy roadmap to consolidate R&I in AWM in BiH. The methodology included an assessment of policies and sector performance, the analysis of stakeholder perceptions, the development of strategic directions and the design of a strategy. Desk research and stakeholder consultations (33 interviews, six workshops, 179 persons in total) were used to take stock of the current situation and expectations for the future. Stakeholders were divided into knowledge supply and knowledge demand, with five and six subcategories, respectively. Relations were established among the key enabling factors, the needs and the capacities of the involved stakeholders. The TOWS (Threats, Opportunities, Weaknesses and Strengths) matrix permitted to identify policy strategies. A Weaknesses – Opportunities, conservative or mini-maxi strategy was selected, owing to the relevance of system weaknesses (such as low investments, poor return of R&I to society or low R&I for AWM adaptation) and opportunities (such as the Green Agenda for the Western Balkans, Smart Specialization or regional partnerships). The policy roadmap was structured along three policy goals: strengthen R&I, strengthen AWM and identify / fund local R&I priorities for AWM. Policy goals included policy instruments promoting eco-efficient use of resources and sustainable development of rural areas.

The increased need for smart management of agricultural resources resulted in the preparation and implementation of H2020 project SMARTWATER. This publication aims to present the main outcomes of SMARTWATER in three years of implementation (2021-2023), to encourage relevant target groups to participate in the action in 2024 and to promote smart management of agricultural resources. During project implementation different results were obtained. SMARTWATER team will continue with different twinning activities in 2024 aiming to promote smart agriculture practices, increase the competencies of scientists and young researchers and disseminate the project outcomes.

This study evaluated the eco-efficiency of rainfed and irrigated maize production in Bosnia and Herzegovina. Environmental impact assessments were performed through energy analysis, carbon footprint, and water scarcity footprint analysis. For economic analysis, gross and net returns and benefit–cost ratios were calculated. Eco-efficiency was measured by the ratio between the net return and environmental criteria. The findings indicate that transition from rainfed to irrigated maize cultivation per unit of land results in a 53.7% higher yield and gross value of production, but also a 69.8% increase in energy input, a 22% rise in greenhouse gas emissions, and a 3.6fold increase in the water scarcity footprint. While a positive link exists in irrigated maize between higher yield and lower carbon footprint per unit of product, rainfed systems outperform in energy efficiency, productivity, profitability, water scarcity footprint, and overall eco-efficiency. Both systems rely heavily on nonrenewable energy sources, with fertilization (energy and carbon footprint), mechanization (carbon footprint), and irrigation (water scarcity) as the main contributors to the negative environmental impacts. The implementation of optimization strategies for these inputs is of paramount importance to reduce environmental impacts and promote sustainability in maize farming in Bosnia and Herzegovina.

The essential resources for the survival of the living world are air, water and land. By its essence land is the only non-renewable natural resource, with a potentially rapid rate of degradation and a very slow process of formation and regeneration. Water and land are resources, characterized by climate, so climate variability inevitably affects the processes in the land and its use, whose testimonies today we could find through the fossil lands. Processes affecting the lands are intensified in the last few decades around the world, such as erosion, water logging, drought, fire, loss of organic matter and the like, are associated with climate change and are visible on the territory of Republika Srpska. The basic task of humans today is to use the land rationally and to preserve it for new generations. On the basis of available measured data and climate models in the future, the following conclusions came out: land use would not be significantly impaired, nor would crop production be endangered; favorable climatic conditions would continue to prevail for the production of corn, wheat, and potatoes, with increased year-on-year variations by the end of the century; due to earlier sowing, water logging would be pronounced; regular maintenance of existing drainage systems should be fully in function, and new ones to be built in geopardize places; for the new, highly intensive orchard establishments and vegetable production, irrigation system should be designed and built; comprehensive solutions of existing erosion processes and prevention of occurrence of new ones should be envisaged, because in future climatic conditions, dry periods of higher intensity might occur, followed by strong rainstorms could cause permanent soil loss due to dried vegetation prone to erosion; considering that the soils of Republika Srpska are very poor in humus, i.e. organic carbon, it is necessary to apply agrotechnical measures to increase the intake of organic matter. Intentional burning of crop residues must be severely punished. Continuous monitoring of soil fertility on georeferenced locations is indispensable (pH, macroelements (NPK), content of organic matter, water-physical properties of soil) for better data comparison and observation of the direction of impact, whether positive or negative, in order to plan and take timely adaptation measures, ensuring proper and sustainable land use and climate change mitigation.
