Agricultural Land Expansion

Land use and land cover in the Dano catchment is characterized by a rapid conversion from seminatural vegetation (fallow) to agriculture (cropland). The study compares both the saturated (Ks) and the unsaturated (Kh) hydraulic conductivities under cropland and fallow in the catchment to gain insights into the effect of the current land use on soil water dynamics. Hydraulic conductivity was measured under forty-two (42) pairs of adjacent cropland-fallow plots using a Hood infiltrometer. Ks, Kh, bulk density, and soil texture were further compared using a paired two-tailed Student’s t-test (p=0.05). The results showed that both Ks and Kh are highly variable irrespective of the land use type (coefficient of variation > 100%). The results also showed that Ks was significantly higher (1.16-fold on average) under fallow compared to cropland. As for Kh, the results showed that, from −2 cm to zero tension heads (h), Kh under cropland and fallow is not significantly different; however, as the supplied tension decreases up to the saturation state, Kh under fallow becomes statistically higher compared to cropland. No significant difference was found between soil textures and bulk density under cropland and fallow meaning that the observed differences of Ks and Kh under cropland and fallow were caused by land use and not preexisting difference in texture. These results suggest an increasing risk of erosion, soil fertility reduction, and flood in the catchment because of agricultural land expansion.

PurposeLiquidity is an important aspect of market efficiency. The purpose of this paper is threefold: first, this paper aims to discuss indicators that provide information about liquidity in agricultural land markets. Second, this paper aims to reflect on determinants of market liquidity and analyze the relationship with land prices. Third, this paper aims to conduct an empirical analysis for Germany that illustrates these concepts and allows hypothesis testing.Design/methodology/approachThis study reviews liquidity dimensions and measurement in financial markets and derives indicators applicable to farmland markets. In an empirical analysis, this study exhibits the spatial and temporal variability of land market liquidity in Lower Saxony, a German federal state with the highest agricultural production value. This study uses a rich dataset that includes 72,547 sale transactions of arable land between 1990 and 2018. The research focuses on volume-based (number of transactions, volume and turnover) and time-based (trading frequency and durations) measures. A panel vector autoregression and Granger causality tests are applied to investigate the relation between land turnover and land prices.FindingsThe paper confirms the thinness of farmland markets but also reveals regional and temporal heterogeneity of land market liquidity. This study finds that the relation between market liquidity and prices is ambiguous. This study concludes that a high demand from expanding farms absorbs supply shocks regardless of the current price level in agricultural land markets.Originality/valueEven though the relevance of agricultural land markets’ thinness is widely acknowledged in the literature, this paper is one of the first attempts to measure liquidity in agricultural land markets and to explain its relationship with land prices.

This paper examines the causes of agricultural land expansion and deforestation in Tanzania. In the theoretical section, two different—and partly contradicting—sets of hypotheses are outlined. These are based on a subsistence approach, emphasising the food or income requirements of farm households, and a market approach, focussing on the relative profitability of agriculture. The statistical analysis shows that increased agricultural output prices, in particular for annual crops, is a major factor behind agricultural expansion. An increase of 1 per cent in output prices leads to about 1 per cent increase in agricultural area. Other factors such as input prices, technology and economic growth are tested and discussed, but the conclusions are less robust. The controversial role of population growth in explaining deforestation is addressed. Generally the results lend support to the market rather than the subsistence approach.

Agricultural land expansion necessity for food security in Indonesia has been faced by the fact in utilizing marginal land such as shallow peat soil in Central Kalimantan. Among problems encountered in such marginal land are pests and diseases incidence. Farmers practice in dealing with those problems is the chemical pesticides application. Unintended chemical pesticides that fall on/into the soil might have an adverse effect to soil microbes activity. This research aimed to assess the effect of pesticides on functional soil microbes population in peat soil. The research used completely randomized factorial design with two factors. First factor was 7 combinations of types (paraquat and buthylphenylmethyl carbamat (BPMC)) and dosages (50, 100, and 200% of recommended dosage) of pesticides. Second factor was 4 incubation times (1, 7, 14, and 28 days). Following the each of incubation times, the soil samples treated and analyzed for population of phosphate solubilizing microbes, cellulolytic microbes, and N2 fixing bacteria. The results show that phosphate solubilizing fungi population decrease by pesticides treatment. In contrast, pesticides significantly increased the Azospirillum population. Adverse effect to microbes population was found on the first day of incubation, however it recovered at 7 days and longer incubation times. In general, functional microbes population with paraquat application lower than BPMC application.

Agricultural Land Expansion

<p><strong>Abstrak</strong>. Data sumberdaya lahan untuk 511 kabupaten/kota sudah tersedia mencakup peta tanah, peta kesesuaian lahan, dan peta arahan komoditas pertanian, dilengkapi dengan buku paket rekomendasi pengelolaan lahan. Komoditas yang sudah dievaluasi kesesuaian lahannya mencakup padi, jagung, kedelai, bawang merah, cabe merah, tebu, pakan ternak, kakao, dan kelapa sawit. Data sumberdaya lahan tersebut  menjadi bagian penting dalam pengembangan komoditas strategis di Indonesia, terbukti dengan banyaknya permintaan data baik dari Direktorat Jenderal Teknis lingkup Kementerian Pertanian, Kementerian/Lembaga terkait, pengusaha swasta, dan para investor dalam dan luar negeri, serta perguruan tinggi. Peta tematik yang banyak diminati adalah peta kesesuaian lahan dan peta sebaran lahan potensial untuk pengembangan berbagai komoditas strategis, baik untuk intensifikasi di lahan eksisting ataupun lahan ekstensifikasi, terutama di lahan semak belukar yang belum dimanfaatkan. Permasalahan utama adalah belum tersedianya peta penggunaan lahan terkini, sehingga kemungkinan penggunaan lahannya sudah berbeda dan yang diduga potensial untuk perluasan komoditas pertanian ternyata sudah dimanfaatkan. Oleh karena itu, perlu upaya penyediaan peta status penguasaan dan penggunaan lahan terbaru, agar para pengguna data yakin bahwa lahan potensial tersebut benar tersedia di lapangan.</p><p> </p><p><strong>Abstract</strong>. Land resources data for 511 regency/cities is available consisting of soil maps, land suitability maps, and recommended agricultural commodities maps, completed with a land management recommendation package book. Commodities that have been evaluated for land suitability including rice, corn, soybeans, shallots, red chillies, sugar cane, animal feed, cocoa, and palm oil. Land resources data is important in the development of strategic commodities in Indonesia. There has been numerous data requests from the Technical Directorate General of the Ministry of Agriculture, relevant Ministries/Institutions, private entrepreneurs and domestic and foreign investors, and universities.  The most on demand thematic maps are land suitability maps and maps of potential land distribution for developing various strategic commodities both for agricultural intensification and land expansion (extensification). Unfortunately, the up to date landuse map is barely available and the precise area that is potentaly available for agricultural land expansion is hardly defined. Therefore, providing the most recent land status and landuse maps is very important to convince map users that the precise potential area for agricultural land expansion could be axactly defined.</p>
