Neem (Azadirachta indica A. Juss.) being an important tropical tree, traditional neem-based agroforestry (bund/boundary/scattered tree planting with field crops) systems were evaluated for their carbon sequestration (CS) potential, soil quality, pest dynamics and provisioning services in comparison with prevailing grain based system in the tropical India. Results revealed higher economic gain from soil quality services followed by CS in all the agroforestry systems among the non-marketable services, whereas higher provisioning services were obtained with crops alone. In all, total economic value was higher in boundary planting ($ 1053.94/ha/yr) followed by bund planting ($ 961.95/ha/yr) and was lower with scattered planting ($ 939.76/ha/yr). However, the provisioning services ($ 841 - 889/ha/yr) rendered by agroforestry systems were lower than those of agriculture alone ($ 904/ha/yr) but were still significant from ecological and sustainable angles.

Ecosystem services in oil palm plantations owned by smallholders in four villages in the Riau Province, Indonesia were identified and valued. Nine provisioning, three regulating and maintenance, one cultural ecosystem service, and a single ecosystem dis-service, were identified from interviews with 62 farming households. Direct and indirect market valuation methods were used to estimate the total economic value (TEV) of these services, which averaged USD 6520 ha−1 year−1 (range = USD 2970–7729 ha−1 year−1). The values of provisioning services were USD 4331 ha−1 year−1 (range = USD 2263–5489 ha−1 year−1), regulating and maintenance services were valued at USD 1880 ha−1 year−1 (range of USD 707–3110 ha−1 year−1), and cultural services were USD 309 ha−1 year−1. We conclude that identifying and valuing ecosystem services offers an opportunity to improve the environmental and economic sustainability of smallholders in oil palm landscapes in Indonesia.

Traditional Agroforestry

Land-Use Changes (LUCs) are the result of interacting environmental and socioeconomic factors. Although in southern Europe traditional agroforestry systems are an important component of the Mediterranean landscape, intensification and simplification of the rural space coupled with the increasing sensitivity to soil degradation are potentially harmful for the integrity of natural resources and biodiversity stock. The present study introduced a quantitative assessment of rural LUCs that occurred in a region devoted to agriculture and experiencing a progressively higher human impact from both urbanization and land abandonment. The assessment was carried out at the municipality scale along forty years (1970–2010) using data collected every ten years in the framework of the National Census of Agriculture. The Maximum potential Water Capacity (MWC) in the soil, taken as a proxy for agricultural soil quality, and an index of crop intensity have been introduced in the analysis as supplementary variables. A Multiway Factor Analysis (MFA) was developed to evaluate stability or dynamics in the investigated land-use classes. Results illustrate relevant changes in the rural landscape by identifying the classes “moving” towards better soils. An integrated evaluation of rural LUCs and soil resources based on long-time inventories available at an adequate spatial scale is a tool informing policies against soil degradation.

Tree planting on public lands is often hampered due to low or no security of tree tenure rights. Uncertainly over who will take advantage of tree crop will make a reluctance in the planting of trees. This study aimed to observe the tree tenure security in the traditional agroforestry systems in West Sumatra. The results showed different tree tenure security across the study area, where the collateral is determined by the degree of clarity of the rule of local institutions. This has an impact on the selection of tree species and patterns of agroforestry.

The article is devoted doctrinal issues of environmental and economic effectiveness of use land in conditions of infringement of institutional transformations. The modern approaches to the definition of content of ecological and economic effectiveness of land use are analyzed. It is established that the overwhelming majority of domestic researchers interpret this notion regarding the use of agricultural land or farm land. It is proved that such an approach is justified, taking into account the structure of the land fund of Ukraine. However, this reduces other goals of the land user and functions of the land. It is proposed to investigate the category of ecological and economic effectiveness of land use in accordance with the provisions of the ecological economics, social welfare theory, and concept of total economic value. Based on the classification of land functions, the criteria of selection material content and social form of ecological and economic effectiveness of land use are determined.

In the tropics, products and services provided by the traditional agroforestry systems (TAS) support the basic needs and promote the livelihood of millions of rural people. However, the outcomes and mitigation of TAS, in particular, the social and environmental issues are not systematically addressed. Thus, the objective of the study was to assess the economic, social and environmental outcomes of two important TAS in Bangladesh. This study reports results on prospective analyses using the Date palm and Jackfruit-based TAS practiced in the Jashore and Mymensingh districts of Bangladesh. The results revealed that the TAS enhanced farm productivity and the benefit–cost ratio of both systems were much higher than the general agricultural practices in Bangladesh. The TAS also improved resilience of rural farmers through more efficient water utilization, enhancing soil fertility, improving microclimate, controlling pests and diseases, and diversifying products. At the same time, the farmers’ problems were neglected due to the absence of farmers’ platforms, and also tradeoffs may arise; thus, the social aspects of the TAS farmers had not developed equally. Therefore, the study would recommend minimizing the tradeoffs through enhancing the conservation strategies at farmers’ levels to make the TAS more viable and sustainable land-use practices.
