Suitable land is an important prerequisite for crop cultivation and, given the prospect of climate change, it is essential to assess such suitability to minimize crop production risks and to ensure food security. Although a variety of methods to assess the suitability are available, a comprehensive, objective, and large-scale screening of environmental variables that influence the results—and therefore their accuracy—of these methods has rarely been explored. An approach to the selection of such variables is proposed and the criteria established for large-scale assessment of land, based on big data, for its suitability to maize (Zea mays L.) cultivation as a case study. The predicted suitability matched the past distribution of maize with an overall accuracy of 79% and a Kappa coefficient of 0.72. The land suitability for maize is likely to decrease markedly at low latitudes and even at mid latitudes. The total area suitable for maize globally and in most major maize-producing countries will decrease, the decrease being particularly steep in those regions optimally suited for maize at present. Compared with earlier research, the method proposed in the present paper is simple yet objective, comprehensive, and reliable for large-scale assessment. The findings of the study highlight the necessity of adopting relevant strategies to cope with the adverse impacts of climate change.

Aim: The current study aimed to evaluate the capacity and suitability of land for semi-arid region of Haryana in selected watersheds to identify the major limitations of crop production. Methodology: The study was carried out in Bhiwani district of Haryana in 2017 where eight typical pedons (P) representing four micro-watersheds viz., Motipura (P1 and P2), Sainiwas (P3 and P4), Jhumpa (P5 and P6), Budhsheli (P7 and P8) were studied. Results: The studied pedons were neutral to alkaline in reaction (pH 6.87-9.10), non-saline (EC 0.02-0.21 dS m-1) and low in organic carbon (OC) (0.06-0.27%). Available N, P, K and S were low (42.00-189.00 kg ha-1), low to medium (4.20-17.10 kg ha-1), low to high (62.20-326.50 kg ha-1) and low (0.40-19.20 mg kg-1) in the studied pedons, respectively. Soils were deficient in available Fe and Zn but marginal to sufficient in available Mn and Cu. Interpretation: Soils were classified as IIsf and IIItsf and S3s and N1s according to LCC and irrigation suitability, respectively. The pedons were found suitable (S1) to moderately suitable (S2) for guar (cluster bean), oilseeds (mustard), moderately suitable (S2) to marginally suitable (S3) for pearl millet, gram and forestry, and marginally suitable (S3) for cotton and wheat.

The regency of Sumba Tengah in the province of East Nusa Tenggara relies on rainfall to support its dry land agriculture hence should be supported with land suitability evaluation and cropping pattern design for a more sustainable crop production. This study aims to evaluate land suitability for food crops in Sumba Tengah and formulate the appropriate precipitation-based cropping patterns. This work was carried out from March to June 2015. Stages of research were: 1) characterizing land attributes (climate and soil) by soil analysis and desk study, 2) assessing land suitability level by comparing land attributes and crops requirements, and 3) composing feasible cropping patterns by using water balance method. Soils of Sumba Tengah varied from sandy to clayey with low to neutral pH and low to very high content of organic carbon and nitrogen. Phosphate and potassium availability was very low. Sumba Tengah was exposed to only four wet months a year with annual precipitation of less than 2000 mm. This region was highly and moderately suitable for growing paddy, maize, tubers, and legumes. It was not suitable for wheat. Some of the northern part was arable merely for one cropping season in a year, mostly from December to April, with the alternative of growing paddy or other crops. The remaining was likely to cultivate for two cropping seasons. Legumes were recommended to include in the rotation for soil conservation. Shortage of irrigation led to the unlikeliness of three cropping seasons in a year.

Management Interventions

Land Evaluation System using the modified Food and Agriculture Organization framework was carried out to assess the suitability of various important crops to Quingua soil series. Corresponding sound management interventions were then formulated over the identified production constraints. This was done to achieve a more productive and sustainable rice-based farming. The system generates a more specific land utilization type in which spatial and climatic variabilities are recognized.  The data used for land suitability evaluation was extracted from 2011-2012 cropping seasons. Analysis disclosed that Quingua series in Talavera and Sto. Domingo, Nueva Ecija, Philippines, representing irrigated and irrigation-supplemented lowlands, respectively, has high flexibility to growing various types of crops due to its favorable land attributes. Hence, crop intensification is highly recommended provided that minor limitations on soil organic matter, drainage, temperature, and seasonal flooding are offset. Multiple cropping system that involves off-season vegetable production and growing of cash or high-value crops in combination or rotation with rice dominates the farms’ landscape. This practice had generated varying levels of return on investment (ROI) from negative to more than 1000% as affected primarily by climate and farm management. Designing market-driven cropping systems under good management strategies can generate stable ROIs’ ten times higher than the production cost, hence, a more productive and profitable enterprise. Furthermore, soils of the same soil series exhibit similar characteristics or properties that require the same level of management in achieving the desired production output. Thus, information obtained from land suitability evaluation can serve as an effective tool for the government’s specific crop production program and agro-technology promotion.
