Conversion of agricultural land in urban areas is most prevalent in wetlands, thus threatening food availability and loss of multifunctional land. In the last five years, the wetland area in Bogor City has dropped dramatically to 321 ha (BPS of Bogor City, 2016). Control of the rate of conversion of wetland in Bogor City is regulated by Local Regulation number 8 year 2011 concerning Bogor City Spatial Plan (RTRW Kota Bogor) 2011-2031. However, its implementation is less effective so that there is a need for economic instruments to support it. The purpose of this study is to describe the wetland conversion in Bogor City and budgetary strategies in order to control it. Spatial analysis with overlay method was used to and resulted in a land conversion pattern which was dominated by housing area of 1 137.33 ha (47.08%) and garden 254.28 ha (10.53%). The conversion pattern was used as the basis of multiple linear regression analysis of factors affecting wetland area in Bogor City during 2000-2015 which results were: production amount (significant at α 1%); building area (significant at α 5 %); realization of Bogor City Agricultural Service budget (not significant) with R2 value = 86.6%. Wetland conversion control was conducted through budget strategies which are analyzed with Analitycal Hierrachy Process (AHP) calculation, resulting as follows: (1) socialization budget; (2) budget for formulating local regulation; (3)budget sharing with the central/provincial government; (4) streamlining the role of the private; (5) budget supervision; (6)budget for (land banking); (7) incentives and disincentives for farmers.

Pepper is one of the most popular herbs from Aceh plantations. Especially pepper farmers in Aceh are now starting to pay attention to pepper to be developed with the aim of increasing income and welfare. In other words, Pepper became the most popular commodity in the world trade. Because various countries use this pepper as a spice cooking kitchen. On the other hand, due to the development of food business, the development of pharmaceutical industry, cosmetics using pepper as one of the raw materials, the increasing of world consumption, domestic consumption is increasing with the increase of pepper based food industry products. As a result of high pepper demand causes problems for Acehnese farmers in the limitations of pepper production. One of them agricultural land converted into non-agricultural such as housing, buildings and shops. So that agricultural land becomes reduced and become a problem for pepper farmers themselves in developing pepper. Other causes of problems are also caused by pests and diseases, especially wilt disease, leaf curling disease and stem rot disease. Research Objectives to determine the factors that are considered in the development of pepper, as well as to know the appropriate pepper development strategy. The research method used is case study method. Technique Data collection is used with interview approach. The results of the analysis show that the internal factors affecting pepper development are seeds, pesticide, natural resources, fertilizer and human resources. While on external factors that include government, markets,prices, competitors,pest and diseases. Based on the result of SWOT analysis, the value of IFAS (Internal Strategic Factors Analysis Summary) of 1.756 and EFAS (External Strategic Factors Analysis Summary) of 2.773 are in quadrant I, then a suitable development strategy for pepper development strategy is aggressive strategy which means the business is very possible To continue to grow, to increase growth and to achieve maximum progress, where aggressive strategy is a very favorable condition, opportunities and strength so large that business actors can take advantage of opportunities and strengths that exist maximally.

Agricultural land is a limited natural resource with increasing economic value. This study analyses land rental relationships in Slovakia, including legal rental regulations, and identifies the impact of certain factors, such as the European Union Common Agricultural Policy (CAP) payments, and geographical and economic factors on land rental prices. From the results of econometric models, it was found that certain CAP payments have an effect on rental prices, mainly the single area payment scheme (SAPS), payments for agri-environmental-climate schemes (AECS), and animal welfare, which were found to have positive effects. Other important factors found to influence rental prices are economic indicators (such as total revenue share of total costs, share of revenue from agricultural production in terms of total revenue, share of production costs as a percentage of total costs, wages, and number of employees) and geographical factors (such as region or partial production areas). However, the distance of the farm from the district city (LAU 1) and the share of farmland affected by natural constraints do not considerably affect rental prices in Slovakia. Land consolidation is a statistically significant factor according to the models; however, its impact is almost zero. Knowledge of these factors constitutes important know-how, not only for policy makers but also for the actors operating in the land rental market (e.g., landlords, tenants, experts on land valuation, and real estate agents).

Nearly every village in Central and Eastern European countries with heavily collectivized agriculture has its collective farm premises that encompass substantial parts of the village area, were built in the sixties, and now are unable to be used in former ways. The aim of the paper is to identify indicators that are relevant for spatial disparities in the utilization of agricultural premises thirty years after the fall of the Iron Curtain. The location and its area of all pre-1989 rural farm premises within two NUTS 3 regions of the Czech Republic with its current uses were identified, and differences in present uses were tested against agri-natural and socio-economic characteristics (of the municipalities where rural farm premises are located) obtained from national databases. From a global point of view, socio-economic characteristics of municipalities were found to be exceedingly more important than agri-natural—thus, changing of uses is rather dependent on socio-economic context than on geographical preconditions of agriculture. Surprisingly, agricultural use or re-use can be primarily found in municipalities not suitable for intensive agriculture located in the fodder crops and potatoes areas of agricultural production with the highest shares of permanent grassland on agricultural land. On the other hand, areas with the best preconditions for agriculture tend to re-use former farm premises for non-agricultural production.
